Various economic indicators such as GDP, exchange rates, interest rates, and unemployment have a substantial impact on the stock market. Time series models are the traditional methods used to predict stock market changes. In this paper, a machine learning method, Bayesian Additive Regression Tree (BART) is used in predicting stock market indexes based on multiple economic indicators. BART can be used to model heterogeneous treatment effects, and thereby works well when models are misspecified. It also has the capability to handle non-linear main effects and multi-way interactions without much input from financial analysts. In this research, BART is proposed to provide a reliable prediction on day-to-day stock market activities. By comparing the analysis results from BART and with time series method, BART can perform well and has better prediction capability than the traditional methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BART" title="BART">BART</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian" title=" Bayesian"> Bayesian</a>, <a href="https://publications.waset.org/abstracts/search?q=predict" title=" predict"> predict</a>, <a href="https://publications.waset.org/abstracts/search?q=stock" title=" stock"> stock</a> </p> <a href="https://publications.waset.org/abstracts/124504/forecasting-stock-indexes-using-bayesian-additive-regression-tree" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124504.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> BART Matching Method: Using Bayesian Additive Regression Tree for Data Matching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gianna%20Zou">Gianna Zou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Propensity score matching (PSM), introduced by Paul R. Rosenbaum and Donald Rubin in 1983, is a popular statistical matching technique which tries to estimate the treatment effects by taking into account covariates that could impact the efficacy of study medication in clinical trials. PSM can be used to reduce the bias due to confounding variables. However, PSM assumes that the response values are normally distributed. In some cases, this assumption may not be held. In this paper, a machine learning method - Bayesian Additive Regression Tree (BART), is used as a more robust method of matching. BART can work well when models are misspecified since it can be used to model heterogeneous treatment effects. Moreover, it has the capability to handle non-linear main effects and multiway interactions. In this research, a BART Matching Method (BMM) is proposed to provide a more reliable matching method over PSM. By comparing the analysis results from PSM and BMM, BMM can perform well and has better prediction capability when the response values are not normally distributed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BART" title="BART">BART</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayesian" title=" Bayesian"> Bayesian</a>, <a href="https://publications.waset.org/abstracts/search?q=matching" title=" matching"> matching</a>, <a href="https://publications.waset.org/abstracts/search?q=regression" title=" regression"> regression</a> </p> <a href="https://publications.waset.org/abstracts/149989/bart-matching-method-using-bayesian-additive-regression-tree-for-data-matching" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149989.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">147</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Use Cases Analysis of Free Space Optical Communication System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kassem%20Saab">Kassem Saab</a>, <a href="https://publications.waset.org/abstracts/search?q=Fritzen%20Bart"> Fritzen Bart</a>, <a href="https://publications.waset.org/abstracts/search?q=Yves-Marie%20Seveque"> Yves-Marie Seveque</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The deployment of Free Space Optical Communications (FSOC) systems requires the development of robust and reliable Optical Ground Stations (OGS) that can be easily installed and operated.

Understanding the relationship between risk-related personality metrics as well as laboratory risk behavior and real-life savings behavior can help facilitate the development of effective asset building programs, which are vital for mitigating financial vulnerability and income inequality. As such, this study explored the relationship between personality metrics, laboratory behavior in a risky decision-making task and real-life asset building (savings) behaviors among individuals with low-SES from Miami, Florida (FL). Study participants (12 male, 15 female) included racially and ethnically diverse adults (mean age 41.22 ± 12.65 years), with incomplete higher education (18% had High School Diploma, 30% Associates, and 52% Some College), and low annual income (mean $13,872 ± $8020.43). Participants completed eight self-report surveys and played a widely used risky decision-making paradigm called the Balloon Analogue Risk Task (BART). Specifically, participants played three runs of BART (20 trials in each run; total 60 trials). In addition, asset building behavior data was collected for 24 participants who opened and used savings accounts and completed a 6-month savings program that involved monthly matches, and a final reward for completing the savings program without any interim withdrawals. Each participant’s total savings at the end of this program was the main asset building indicator considered. In addition, a new effective use of average pump bet (EUAPB) indicator was developed to characterize each participant’s ability to place winning bets. This indicator takes the ratio of each participant’s total BART earnings to average pump bet (APB) in all 60 trials. Our findings indicated that EUAPB explained more than a third of the variation in total savings among participants. Moreover, participants who managed to obtain BART earnings of at least 30 cents out of their APB, also tended to exhibit better asset building (savings) behavior. In particular, using this criterion to separate participants into high and low EUAPB groups, the nine participants with high EUAPB (mean BART earnings of 35.64 cents per APB) ended up with higher mean total savings ($255.11), while the 15 participants with low EUAPB (mean BART earnings of 22.50 cents per APB) obtained lower mean total savings ($40.01). All mean differences are statistically significant (2-tailed p  .0001) indicating that the relation between higher EUAPB and higher total savings is robust. Overall, these findings can help refine asset building interventions implemented by policy makers and practitioners interested in reducing financial vulnerability among low-SES population. Specifically, by helping identify individuals who are likely to readily take advantage of savings opportunities (such as matched savings programs) and avoiding the stipulation of unnecessary and expensive financial coaching programs to these individuals. This study was funded by J.P. Morgan Chase (JPMC) and carried out by scientists from Florida International University (FIU) in partnership with Catalyst Miami. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balloon%20analogue%20risk%20task%20%28BART%29" title="balloon analogue risk task (BART)">balloon analogue risk task (BART)</a>, <a href="https://publications.waset.org/abstracts/search?q=matched%20savings%20programs" title=" matched savings programs"> matched savings programs</a>, <a href="https://publications.waset.org/abstracts/search?q=asset%20building%20capability" title=" asset building capability"> asset building capability</a>, <a href="https://publications.waset.org/abstracts/search?q=low-SES%20participants" title=" low-SES participants"> low-SES participants</a> </p> <a href="https://publications.waset.org/abstracts/125031/balloon-analogue-risk-task-bart-performance-indicators-help-predict-outcomes-of-matched-savings-program" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125031.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Evaluating Accessibility to Bangkok Mass Transit System: Case Study of Saphan Taksin Bangkok Mass Transit System Station</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rungpansa%20Noichan">Rungpansa Noichan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Julian%20Dewancker"> Bart Julian Dewancker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Thailand facing the transportation issue because of the rapid economic development. The big issue is the traffic jam, especially in Bangkok. However, recently years Bangkok has operated urban mass transit system for solved transportation problem. The Bangkok Mass Transit System (BTS) skytrain is being operated by the BTS Company Limited under the Bangkok Metropolitan Administration. The passenger satisfaction is a major cause for concern due to the commercial nature. The focus of this paper is to evaluate the passenger satisfaction at the mass transit node by questionnaires survey. The survey was to find out the passenger attitudes. The result shows several important factors that influence the passenger choice of using the BTS as a public transportation mode and the passenger’s opinion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20transportation" title="urban transportation">urban transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20satisfaction" title=" user satisfaction"> user satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility" title=" accessibility"> accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20mass%20transit" title=" Bangkok mass transit"> Bangkok mass transit</a> </p> <a href="https://publications.waset.org/abstracts/71342/evaluating-accessibility-to-bangkok-mass-transit-system-case-study-of-saphan-taksin-bangkok-mass-transit-system-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71342.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Optimization of Energy Consumption with Various Design Parameters on Office Buildings in Chinese Severe Cold Zone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuang%20Guo">Yuang Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Dewancker%20Bart"> Dewancker Bart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The primary energy consumption of buildings throughout China was approximately 814 million tons of coal equivalents in 2014, which accounts for 19.12% of China's total primary energy consumption.

There are growing numbers of industrial building in which promoting heritage conservation maybe a helpful tool for a sustainable city in social, urban restructuring, environmental and economic component. This paper identifies the key attributes of conservation and regeneration industrial building from the literature, were discussed by reviewing its development at home and abroad. The authors have investigated 93 industrial buildings, which were used as industrial building before and reused into buildings with another function afterward. The data to be discussed below were mainly collected from various publications but also from available internet sources. This study focuses on green transformation, historical culture heritage, transformation techniques, and urban regeneration based on the empirical researches on the historical industrial building and site. Moreover, we focus on social, urban environment and sustainable development. The implications of the study provide suggestions for future improvements in the conservation and regeneration of historical industrial building, and inspire new ways of use, so the building becomes flexible and can consequently be adaptable to changes in order to survive time. Therefore, the building does not take into account only its future impact in the environment and society. Instead, it focuses on its entire life cycle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20building" title="industrial building">industrial building</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20conservation" title=" heritage conservation"> heritage conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20transformation" title=" green transformation"> green transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a> </p> <a href="https://publications.waset.org/abstracts/59288/study-on-conservation-and-regeneration-of-the-industrial-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Evaluating Accessibility to Bangkok Mass Transit System: Case Study of Saphan Taksin BTS Station </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rungpansa%20Noichan">Rungpansa Noichan</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Julien%20Dewancker"> Bart Julien Dewancker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Access to the mass transit system, including rapid elevated and underground transport has become an outstanding issue for many cities. The mass transit access development should focus on behavioral responses of the different passenger groups. Moreover, it should consider about the appearance of intent-oriented action related accessibility that was explored from user’s satisfaction and attitudes related to services quality. This study aims to evaluate mass transit accessibility from passenger’s satisfaction, therefore, understanding the passenger’s attitudes about mass transit accessibility. The study area of this research is Bangkok Mass Transit system (BTS Skytrain) at Saphan Taksin station. 200 passengers at Saphan Taksin station were asked to rate the questionnaires survey that considers accessibility aspects of convenience, safety, feeder connectivity, and other dimensions. The survey was to find out the passenger attitudes and satisfaction for access to the BTS station, and the result shows several factors that influence the passenger choice of using the BTS as a public transportation mode and passenger’s opinion that needs to concern for the development mass transit system and accessibility performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20transportation" title="urban transportation">urban transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20satisfaction" title=" user satisfaction"> user satisfaction</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility" title=" accessibility"> accessibility</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20mass%20transit" title=" Bangkok mass transit"> Bangkok mass transit</a> </p> <a href="https://publications.waset.org/abstracts/94546/evaluating-accessibility-to-bangkok-mass-transit-system-case-study-of-saphan-taksin-bts-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94546.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">268</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> Comparison the Energy Consumption with Sustainability in Campus: Case Study of Four American Universities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bifeng%20Zhu">Bifeng Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhekai%20Wang"> Zhekai Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaoyang%20Sun"> Chaoyang Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Dewancker"> Bart Dewancker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Under the tide of promoting sustainable development in the world, American universities that have been committed to sustainable practice and innovation, not only have its sustainable campus construction been in the forefront of the world, but also have developed STARS (The Sustainability Tracking, Assessment & Rating System), which is widely used in the world and highly recognized. At the same time, in the process of global sustainable campus construction, energy problem is often regarded as one of the most important sustainable aspects, even equivalent to the sustainability of campus. Therefore, the relationship between campus energy and sustainability is worth discussing. In this study, four American universities with the highest level evaluated by STARS are selected as examples to compare and analyze the campus energy consumption and the use of new energy, GHG emissions and the overall sustainability of the campus, in order to explore the relationship between campus energy and sustainable construction. It is found that the advantages of sustainable campus construction in the United States are mainly focused on the "software" of management, education, activities, etc. Although different energy-saving measures have been taken in campus energy, the construction results are quite different. Moreover, as an important aspect of sustainable campus, energy can not fully represent the sustainability of campus, but because of the various measures it takes, it can greatly promote the sustainable construction of the whole campus. These measures and construction experiences are worthy of summary and promotion, and have positive reference significance for other universities even communities around the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20campus" title="sustainable campus">sustainable campus</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=STARS%20assessment" title=" STARS assessment"> STARS assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a> </p> <a href="https://publications.waset.org/abstracts/119859/comparison-the-energy-consumption-with-sustainability-in-campus-case-study-of-four-american-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119859.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> From Script to Film: The Fading Voice of the Screenwriter </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ana%20Sofia%20Torres%20Pereira">Ana Sofia Torres Pereira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On January 15th 2015, Peter Bart, editor in chief of Variety Magazine, published an article in the aforementioned magazine posing the following question “Are screenwriters becoming obsolete in Hollywood?” Is Hollywood loosing its interest in well plotted, well written scripts crafted by professionals? That screenwriters have been undervalued, forgotten and left behind since the begging of film, is a well-known fact, but ate they now at the brink of extinction? If fiction films are about people, stories, so, simply put, all about the script, what does it mean to say that the screenwriter is becoming obsolete? What will be the consequences of the possible death of the screenwriter for the cinema world? All of these questions lead us to an ultimate one: What is the true importance of a screenwriter? What can a screenwriter do that a director, for instance, can’t? How should a script be written and read in order not to become obsolete? And what about those countries, like Portugal, for example, in which the figure of the screenwriter is yet to be heard and known? How can screenwriters find their voice in a world driven by the tyrannical voice of the Director? In a demanding cinema world where the Director is considered the author of a film, it’s important to know where we can find the voice of the screenwriter, the true language of the screenplay and the importance this voice and specific language might have for the future of story telling and of film. In a paper that admittedly poses more questions than answers, I will try to unveil the importance a screenplay might have in Hollywood, in Portugal and in the cinema and communication world in general. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cinema" title="cinema">cinema</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=director" title=" director"> director</a>, <a href="https://publications.waset.org/abstracts/search?q=language" title=" language"> language</a>, <a href="https://publications.waset.org/abstracts/search?q=screenplay" title=" screenplay"> screenplay</a>, <a href="https://publications.waset.org/abstracts/search?q=screenwriting" title=" screenwriting"> screenwriting</a>, <a href="https://publications.waset.org/abstracts/search?q=story" title=" story"> story</a> </p> <a href="https://publications.waset.org/abstracts/29999/from-script-to-film-the-fading-voice-of-the-screenwriter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29999.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> The Critical Velocity and Heat of Smoke Outflow in Z-shaped Passage Fires Under Weak Stack Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zekun%20Li">Zekun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Merci"> Bart Merci</a>, <a href="https://publications.waset.org/abstracts/search?q=Miaocheng%20Weng"> Miaocheng Weng</a>, <a href="https://publications.waset.org/abstracts/search?q=Fang%20Liu"> Fang Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Z-shaped passage, widely used in metro entrance/exit passageways, inclined mining laneways, and other applications, features steep slopes and a combination of horizontal and inclined sections. These characteristics lead to notable differences in airflow patterns and temperature distributions compared to conventional confined passages. In fires occurring within Z-shaped passages under natural ventilation with a weak stack effect, the induced airflow may be insufficient to fully confined smoke downstream of the fire source. This can cause smoke back-layering upstream, with the possibility of smoke escaping from the lower entrance located upstream of the fire. Consequently, not all the heat from the fire source contributes to the stack effect. This study combines theoretical analysis and fire simulations to examine the influence of various heat release rates (HRR), passage structures, and fire source locations on the induced airflow velocity driven by the stack effect. An empirical equation is proposed to quantify the strength of the stack effect under different conditions. Additionally, predictive models have been developed to determine the critical induced airflow and to estimate the heat of smoke escaping from the lower entrance of the passage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stack%20effect" title="stack effect">stack effect</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20velocity" title=" critical velocity"> critical velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20outflow" title=" heat outflow"> heat outflow</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/193173/the-critical-velocity-and-heat-of-smoke-outflow-in-z-shaped-passage-fires-under-weak-stack-effect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193173.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">8</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> A System Dynamics Approach to Technological Learning Impact for Cost Estimation of Solar Photovoltaics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rong%20Wang">Rong Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Hasanefendic"> Sandra Hasanefendic</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20von%20Hauff"> Elizabeth von Hauff</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Bossink"> Bart Bossink</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Technological learning and learning curve models have been continuously used to estimate the photovoltaics (PV) cost development over time for the climate mitigation targets. They can integrate a number of technological learning sources which influence the learning process. Yet the accuracy and realistic predictions for cost estimations of PV development are still difficult to achieve. This paper develops four hypothetical-alternative learning curve models by proposing different combinations of technological learning sources, including both local and global technology experience and the knowledge stock. This paper specifically focuses on the non-linear relationship between the costs and technological learning source and their dynamic interaction and uses the system dynamics approach to predict a more accurate PV cost estimation for future development. As the case study, the data from China is gathered and drawn to illustrate that the learning curve model that incorporates both the global and local experience is more accurate and realistic than the other three models for PV cost estimation. Further, absorbing and integrating the global experience into the local industry has a positive impact on PV cost reduction. Although the learning curve model incorporating knowledge stock is not realistic for current PV cost deployment in China, it still plays an effective positive role in future PV cost reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title="photovoltaic">photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics" title=" system dynamics"> system dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20learning" title=" technological learning"> technological learning</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20curve" title=" learning curve"> learning curve</a> </p> <a href="https://publications.waset.org/abstracts/168940/a-system-dynamics-approach-to-technological-learning-impact-for-cost-estimation-of-solar-photovoltaics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168940.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">96</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">16</span> Entrepreneurial Support Ecosystem: Role of Research Institutes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayna%20Yusubova">Ayna Yusubova</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Clarysse"> Bart Clarysse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores role of research institutes in creation of support ecosystem for new technology-based ventures. Previous literature introduced research institutes as part of business and knowledge ecosystem, very few studies are available that consider a research institute as an ecosystem that support high-tech startups at every stage of development. Based on a resource-based view and a stage-based model of high-tech startups growth, this study aims to analyze how a research institute builds a startup support ecosystem by attracting different stakeholders in order to help startups to overcome resource. This paper is based on an in-depth case study of public research institute that focus on development of entrepreneurial ecosystem in a developed region. Analysis shows that the idea generation stage of high-tech startups that related to the invention and development of product or technology for commercialization is associated with a lack of critical knowledge resources. Second, at growth phase that related to market entrance, high-tech startups face challenges associated with the development of their business network. Accordingly, the study shows the support ecosystem that research institute creates helps high-tech startups overcome resource gaps in order to achieve a successful transition from one phase of growth to the next. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20technology-based%20firms" title="new technology-based firms">new technology-based firms</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystems" title=" ecosystems"> ecosystems</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20incubators" title=" business incubators"> business incubators</a>, <a href="https://publications.waset.org/abstracts/search?q=research%20instutes" title=" research instutes"> research instutes</a> </p> <a href="https://publications.waset.org/abstracts/49103/entrepreneurial-support-ecosystem-role-of-research-institutes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49103.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">15</span> Treatment of Healthcare Wastewater Using The Peroxi-Photoelectrocoagulation Process: Predictive Models for Chemical Oxygen Demand, Color Removal, and Electrical Energy Consumption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Fekadu%20A.">Samuel Fekadu A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Esayas%20Alemayehu%20B."> Esayas Alemayehu B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bultum%20Oljira%20D."> Bultum Oljira D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Seid%20Tiku%20D."> Seid Tiku D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Dessalegn%20Dadi%20D."> Dessalegn Dadi D.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Van%20Der%20Bruggen%20A."> Bart Van Der Bruggen A.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The peroxi-photoelectrocoagulation process was evaluated for the removal of chemical oxygen demand (COD) and color from healthcare wastewater. A 2-level full factorial design with center points was created to investigate the effect of the process parameters, i.e., initial COD, H₂O₂, pH, reaction time and current density. Furthermore, the total energy consumption and average current efficiency in the system were evaluated. Predictive models for % COD, % color removal and energy consumption were obtained. The initial COD and pH were found to be the most significant variables in the reduction of COD and color in peroxi-photoelectrocoagulation process. Hydrogen peroxide only has a significant effect on the treated wastewater when combined with other input variables in the process like pH, reaction time and current density. In the peroxi-photoelectrocoagulation process, current density appears not as a single effect but rather as an interaction effect with H₂O₂ in reducing COD and color. Lower energy expenditure was observed at higher initial COD, shorter reaction time and lower current density. The average current efficiency was found as low as 13 % and as high as 777 %. Overall, the study showed that hybrid electrochemical oxidation can be applied effectively and efficiently for the removal of pollutants from healthcare wastewater. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20oxidation" title="electrochemical oxidation">electrochemical oxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=UV" title=" UV"> UV</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20pollutants%20removals" title=" healthcare pollutants removals"> healthcare pollutants removals</a>, <a href="https://publications.waset.org/abstracts/search?q=factorial%20design" title=" factorial design"> factorial design</a> </p> <a href="https://publications.waset.org/abstracts/162986/treatment-of-healthcare-wastewater-using-the-peroxi-photoelectrocoagulation-process-predictive-models-for-chemical-oxygen-demand-color-removal-and-electrical-energy-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162986.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">14</span> MAGE-A3 and PRAME Gene Expression and EGFR Mutation Status in Non-Small-Cell Lung Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20Checiches">Renata Checiches</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Coche"> Thierry Coche</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20F.%20Delahaye"> Nicolas F.

EGFR, KRAS and BRAF mutation status was determined in a subset to investigate associations with MAGE A3 and PRAME expression. Methods: We conducted a single-centre, uncontrolled, retrospective study of 1260 tissue-bank samples from stage IA-III resected NSCLC. The prognostic value of antigen expression (qRT-PCR) was determined by hazard-ratio and Kaplan-Meier curves. Results: Thirty-seven percent (314/844) of tumours expressed MAGE-A3, 66% (723/1092) expressed PRAME and 31% (239/839) expressed both. Respective frequencies in squamous-cell tumours and adenocarcinomas were 43%/30% for MAGE A3 and 80%/44% for PRAME. No correlation with stage, tumour size or patient age was found. Overall, no prognostic value was identified for either antigen. A trend to poorer overall survival was associated with MAGE-A3 in stage IIIB and with PRAME in stage IB. EGFR and KRAS mutations were found in 10.1% (28/311) and 33.8% (97/311) of tumours, respectively. EGFR (but not KRAS) mutation status was negatively associated with PRAME expression. Conclusion: No clear prognostic value for either PRAME or MAGE A3 was observed in the overall population, although some observed trends may warrant further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MAGE%20A3" title="MAGE A3">MAGE A3</a>, <a href="https://publications.waset.org/abstracts/search?q=PRAME" title=" PRAME"> PRAME</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer-testis%20gene" title=" cancer-testis gene"> cancer-testis gene</a>, <a href="https://publications.waset.org/abstracts/search?q=NSCLC" title=" NSCLC"> NSCLC</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a>, <a href="https://publications.waset.org/abstracts/search?q=EGFR" title=" EGFR"> EGFR</a> </p> <a href="https://publications.waset.org/abstracts/54549/mage-a3-and-prame-gene-expression-and-egfr-mutation-status-in-non-small-cell-lung-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54549.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">382</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">13</span> The Hydrotrope-Mediated, Low-Temperature, Aqueous Dissolution of Maize Starch</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jeroen%20Vinkx">Jeroen Vinkx</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20A.%20Delcour"> Jan A.

A high-temperature autoclaving process is necessary, followed by cooling the solution below its boiling point. The cooled solution is inherently unstable over time. Gelation and retrogradation processes, along with aggregation-induced by undissolved starch remnants, result in starch precipitation. We recently observed the spontaneous gelatinization of native maize starch (MS) in aqueous sodium salicylate (NaSal) solutions at room temperature. A hydrotropic mode of solubilization is hypothesized. Differential scanning calorimetry (DSC) and polarized optical microscopy (POM) of starch dispersions in NaSal solution were used to demonstrate the room temperature gelatinization of MS at different concentrations of MS and NaSal. The DSC gelatinization peak shifts to lower temperatures, and the gelatinization enthalpy decreases with increasing NaSal concentration. POM images confirm the same trend through the disappearance of the ‘Maltese cross’ interference pattern of starch granules. The minimal NaSal concentration to induce complete room temperature dissolution of MS was found to be around 15-20 wt%. The MS content of the dispersion has little influence on the amount of NaSal needed to dissolve it. The effect of the NaSal solution on the MS molecular weight was checked with HPSEC. It is speculated that, because of its amphiphilic character, NaSal enhances the solubility of MS in water by association with the more hydrophobic MS moieties, much like urea, which has also been used to enhance starch dissolution in alkaline aqueous media. As such small molecules do not tend to form micelles in water, they are called hydrotropes rather than surfactants. A minimal hydrotrope concentration (MHC) is necessary for the hydrotropes to structure themselves in water, resulting in a higher solubility of MS. This is the case for the system MS/NaSal/H₂O. Further investigations into the putative hydrotropic dissolution mechanism are necessary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydrotrope" title="hydrotrope">hydrotrope</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolution" title=" dissolution"> dissolution</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20starch" title=" maize starch"> maize starch</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20salicylate" title=" sodium salicylate"> sodium salicylate</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatinization" title=" gelatinization"> gelatinization</a> </p> <a href="https://publications.waset.org/abstracts/137467/the-hydrotrope-mediated-low-temperature-aqueous-dissolution-of-maize-starch" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137467.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> The Three-Dimensional Kinematics of the Sprint Start in Young Elite Sprinters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ilbeigi">Saeed Ilbeigi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Van%20Gheluwe"> Bart Van Gheluwe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to identify the three-dimensional kinematics of the sprint start during the start phase of the sprint. The purpose of this study was to identify the three-dimensional kinematics of the sprint start during the start phase of the sprint. Moreover, the effect of anthropometrical factors such as skeletal muscle mass, thigh girth, and calf girth also were considered on the kinematics of the sprint start. Among all young sprinters involved in the national Belgium league, sixty sprinters (boys: 14.7 ± 1.8 years and girls: 14.8±1.5 years) were randomly selected. The kinematics data of the sprint start were collected with a Vicon® 620 motion analysis system equipped with 12 infrared cameras running at 250 Hz and running the Vicon Data Station software. For statistical analysis, T-tests and ANOVA׳s with Scheffé post hoc test were used and the significant level was set as p≤0.05. The results showed that the angular positions of the lower joints of the young sprinters in the set position were comparable with adult figures from literature, however, with a greater range of joint extension. The most significant difference between boys and girls was found in the set position, where the boys presented a more dorsiflexed ankle. No further gender effect was observed during the leaving the blocks and contact phase. The sprinters with a higher age, skeletal muscle mass, thigh girth, and calf girth displayed a better angular position of the lower joints (e.g. ankle, knee, hip) in the set position, a more optimal angular position for the foot and knee for absorbing impact forces at foot contact and finally a higher range of flexion/extension motion to produce force and power when leaving the blocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometry" title="anthropometry">anthropometry</a>, <a href="https://publications.waset.org/abstracts/search?q=kinematics" title=" kinematics"> kinematics</a>, <a href="https://publications.waset.org/abstracts/search?q=sprint%20start" title=" sprint start"> sprint start</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20elite%20sprinters" title=" young elite sprinters"> young elite sprinters</a> </p> <a href="https://publications.waset.org/abstracts/72635/the-three-dimensional-kinematics-of-the-sprint-start-in-young-elite-sprinters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> AquaCrop Model Simulation for Water Productivity of Teff (Eragrostic tef): A Case Study in the Central Rift Valley of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yenesew%20Mengiste%20Yihun">Yenesew Mengiste Yihun</a>, <a href="https://publications.waset.org/abstracts/search?q=Abraham%20Mehari%20Haile"> Abraham Mehari Haile</a>, <a href="https://publications.waset.org/abstracts/search?q=Teklu%20Erkossa"> Teklu Erkossa</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Schultz"> Bart Schultz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Teff (Eragrostic tef) is a staple food in Ethiopia. The local and international demand for the crop is ever increasing pushing the current price five times compared with that in 2006. To meet this escalating demand increasing production including using irrigation is imperative. Optimum application of irrigation water, especially in semi-arid areas is profoundly important. AquaCrop model application in irrigation water scheduling and simulation of water productivity helps both irrigation planners and agricultural water managers. This paper presents simulation and evaluation of AquaCrop model in optimizing the yield and biomass response to variation in timing and rate of irrigation water application. Canopy expansion, canopy senescence and harvest index are the key physiological processes sensitive to water stress. For full irrigation water application treatment there was a strong relationship between the measured and simulated canopy and biomass with r2 and d values of 0.87 and 0.96 for canopy and 0.97 and 0.74 for biomass, respectively. However, the model under estimated the simulated yield and biomass for higher water stress level. For treatment receiving full irrigation the harvest index value obtained were 29%. The harvest index value shows generally a decreasing trend under water stress condition. AquaCrop model calibration and validation using the dry season field experiments of 2010/2011 and 2011/2012 shows that AquaCrop adequately simulated the yield response to different irrigation water scenarios. We conclude that the AquaCrop model can be used in irrigation water scheduling and optimizing water productivity of Teff grown under water scarce semi-arid conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AquaCrop" title="AquaCrop">AquaCrop</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20smart%20agriculture" title=" climate smart agriculture"> climate smart agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=teff" title=" teff"> teff</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20security" title=" water security"> water security</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20stress%20regions" title=" water stress regions"> water stress regions</a> </p> <a href="https://publications.waset.org/abstracts/39238/aquacrop-model-simulation-for-water-productivity-of-teff-eragrostic-tef-a-case-study-in-the-central-rift-valley-of-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39238.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">406</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> A Sociological Investigation on the Population and Public Spaces of Nguyen Cong Tru, a Soviet-Style Collective Housing Complex in Hanoi in Regards to Its New Community-Focused Architectural Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Duy%20Nguyen%20Do">Duy Nguyen Do</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Julien%20Dewancker"> Bart Julien Dewancker</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many Soviet-style collective housing complexes (also known as KTT) were built since the 1960s in Hanoi to support the post-war population growth. Those low-rise buildings have created well-knitted, robust communities, so much to the point that in most complexes, all families in one housing block would know each other, occasionally interact and provide supports in need. To understand how the community of collective housing complexes have developed and maintained in order to adapt their advantages into modern housing designs, the study is executed on the site of Nguyen Cong Tru KTT. This is one of the oldest KTT in Hanoi, completed in 1954. The complex also has an unique characteristic that is closely related to its community: the symbiotic relationship with Hom – a flea market that has been co-developing with Nguyen Cong Tru KTT since its beginning. The research consists of three phases: the first phase is a sociological investigation with Nguyen Cong Tru KTT’s current residents and a site survey on the complex’s economic and architectural characteristics. In the second phase, the collected data is analyzed to find out people’s opinions with the KTT’s concerning their satisfaction with the current housing status, floor plan organization, community, the relationship between the KTT’s dedicated public spaces with the flea market and their usage. Simultaneously, the master plan and gathered information regarding current architectural characteristics of the complex are also inspected. On the third phase, the analyses’ results will provide information regarding the issues, positive trends and significant historical features of the complex’s architecture in order to generate suitable proposals for the redesigning project of Nguyen Cong Tru KTT, a design focused on vitalizing modern apartments’ communities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20community" title="collective house community">collective house community</a>, <a href="https://publications.waset.org/abstracts/search?q=collective%20house%20public%20space" title=" collective house public space"> collective house public space</a>, <a href="https://publications.waset.org/abstracts/search?q=community-focused" title=" community-focused"> community-focused</a>, <a href="https://publications.waset.org/abstracts/search?q=redesigning%20Nguyen%20Cong%20Tru%20KTT" title=" redesigning Nguyen Cong Tru KTT"> redesigning Nguyen Cong Tru KTT</a>, <a href="https://publications.waset.org/abstracts/search?q=sociological%20investigation" title=" sociological investigation "> sociological investigation </a> </p> <a href="https://publications.waset.org/abstracts/68487/a-sociological-investigation-on-the-population-and-public-spaces-of-nguyen-cong-tru-a-soviet-style-collective-housing-complex-in-hanoi-in-regards-to-its-new-community-focused-architectural-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68487.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">363</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Economic Analysis of Rainwater Harvesting Systems for Dairy Cattle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Cecilia%20Muhirirwe">Sandra Cecilia Muhirirwe</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Van%20Der%20Bruggen"> Bart Van Der Bruggen</a>, <a href="https://publications.waset.org/abstracts/search?q=Violet%20Kisakye"> Violet Kisakye</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Economic analysis of Rainwater harvesting (RWH) systems is vital in search of a cost-effective solution to water unreliability, especially in low-income countries. There is little literature focusing on the financial aspects of RWH for dairy farmers. The main purpose was to assess the economic viability of rainwater harvesting for diary framers in the Rwenzori region. The study focused on the use of rainwater harvesting systems from the rooftop and collection in above surface tanks. Daily rainfall time series for 12 years was obtained across nine gauging stations. The daily water balance equation was used for optimal sizing of the tank. Economic analysis of the investment was carried out based on the life cycle costs and the accruing benefits for the period of 15 years. Roof areas were varied from 75m2 as the minimum required area to 500m2 while maintaining the same number of cattle and keeping the daily water demand constant. The results show that the required rainwater tank sizes are very large and may be impractical to install due to the strongly varying terrain and the initial cost of investment. In all districts, there is a significant reduction of the volume of the required tank with an increasing collection area. The results further show that increasing the collection area has a minor effect on reducing the required tank size. Generally, for all rainfall areas, the reliability increases with an increase in the roof area. The results indicate that 100% reliability can only be realized with very large collection areas that are impractical to install. The estimated benefits outweigh the cost of investment. The Present Net Value shows that the investment is economically viable and investment with a short payback of a maximum of 3 years for all the time series in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dairy%20cattle" title="dairy cattle">dairy cattle</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=rainwater%20harvesting" title=" rainwater harvesting"> rainwater harvesting</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20analysis" title=" economic analysis"> economic analysis</a> </p> <a href="https://publications.waset.org/abstracts/138714/economic-analysis-of-rainwater-harvesting-systems-for-dairy-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138714.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">204</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> The Importance of a Coating and Architecture of the Surface Metal on the Survival of Uncemented Total Knee Arthroplasty</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raymond%20Puijk">Raymond Puijk</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Rassir"> Rachid Rassir</a>, <a href="https://publications.waset.org/abstracts/search?q=Inger%20N.%20Sierevelt"> Inger N.

This study explores the variety of MSS-coating combinations and compares their mid-long-term survivorships with cemented TKAs, by using data from the Dutch Arthroplasty Register. Methods: A total of 235,500 cemented and 11,132 uncemented primary TKAs with a median follow-up of 5.1 years were included. MSS-coating combinations were (1) Porous-uncoated (n=8986), (2) Beaded-hydroxyapatite (HA)(n=1093), (3) Matte-uncoated (n=846), (4) Matte-Titanium-nitride (TiN) (n=207). Five- and 10-year revision-free survival for all-cause revisions, and aseptic loosening of the tibial component, were calculated and compared by using Kaplan-Meier, Log-rank tests, and multivariable Cox proportional hazard regression analyses. Results: Ten-year survival rates with all-cause revisions as an endpoint, were 94.2% for cement, and 94.7%, 96.3%, 92.1%, and 79.0% for porous-uncoated, beaded-HA, matte-uncoated, and Matte-TiN, respectively (p<0.01). Rates for aseptic loosening were 98.8% for cemented, and 98.7%, 99.8%, 97.2%, and 94.9% for the uncemented, respectively (p<0.01).The beaded-HA implants were half the risk for an all-cause revision compared to cemented implants (p<0.01). Matte-uncoated and matte-TiN implants were at more risk of an all-cause revision than cemented implants (p=0.01, p<0.01). Proportions of revisions for aseptic loosening were comparable among most groups. Conclusion: Based on Dutch registry data, four main MSS-coating combinations among uncemented TKAs were found. survivorships for all-cause revisions and aseptic release differed widely between groups. Beaded-HA and porous-uncoated implants had the best survival rates among the uncemented TKAs and were non-inferior to the cemented TKAs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=total%20knee%20arthroplasty" title="total knee arthroplasty">total knee arthroplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=cement" title=" cement"> cement</a>, <a href="https://publications.waset.org/abstracts/search?q=uncemented" title=" uncemented"> uncemented</a>, <a href="https://publications.waset.org/abstracts/search?q=cementless%3B" title=" cementless;"> cementless;</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20surface%20structure" title=" metal surface structure"> metal surface structure</a>, <a href="https://publications.waset.org/abstracts/search?q=coating" title=" coating"> coating</a> </p> <a href="https://publications.waset.org/abstracts/156589/the-importance-of-a-coating-and-architecture-of-the-surface-metal-on-the-survival-of-uncemented-total-knee-arthroplasty" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156589.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">152</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Off-Body Sub-GHz Wireless Channel Characterization for Dairy Cows in Barns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Said%20Benaissa">Said Benaissa</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Plets"> David Plets</a>, <a href="https://publications.waset.org/abstracts/search?q=Emmeric%20Tanghe"> Emmeric Tanghe</a>, <a href="https://publications.waset.org/abstracts/search?q=Jens%20Trogh"> Jens Trogh</a>, <a href="https://publications.waset.org/abstracts/search?q=Luc%20Martens"> Luc Martens</a>, <a href="https://publications.waset.org/abstracts/search?q=Leen%20Vandaele"> Leen Vandaele</a>, <a href="https://publications.waset.org/abstracts/search?q=Annelies%20Van%20Nuffel"> Annelies Van Nuffel</a>, <a href="https://publications.waset.org/abstracts/search?q=Frank%20A.%20M.%20Tuyttens"> Frank A.

In large sized farms, traditional methods based on direct observation or analysis of video recordings become labour-intensive and time-consuming. Thus, automatic monitoring systems using sensors have become increasingly important to continuously and accurately track the health status of dairy cows. Wireless sensor networks (WSNs) and internet-of-things (IoT) can be effectively used in health tracking of dairy cows to facilitate herd management and enhance the cow welfare. Since on-cow measuring devices are energy-constrained, a proper characterization of the off-body wireless channel between the on-cow sensor nodes and the back-end base station is required for a power-optimized deployment of these networks in barns. The aim of this study was to characterize the off-body wireless channel in indoor (barns) environment at 868 MHz using LoRa nodes. LoRa is an emerging wireless technology mainly targeted at WSNs and IoT networks. Both large scale fading (i.e., path loss) and temporal fading were investigated. The obtained path loss values as a function of the transmitter-receiver separation were well fitted by a lognormal path loss model. The path loss showed an additional increase of 4 dB when the wireless node was actually worn by the cow. The temporal fading due to movement of other cows was well described by Rician distributions with a K-factor of 8.5 dB. Based on this characterization, network planning and energy consumption optimization of the on-body wireless nodes could be performed, which enables the deployment of reliable dairy cow monitoring systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=channel" title="channel">channel</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20modelling" title=" channel modelling"> channel modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20monitoring" title=" cow monitoring"> cow monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=dairy%20cows" title=" dairy cows"> dairy cows</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20monitoring" title=" health monitoring"> health monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT" title=" IoT"> IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=LoRa" title=" LoRa"> LoRa</a>, <a href="https://publications.waset.org/abstracts/search?q=off-body%20propagation" title=" off-body propagation"> off-body propagation</a>, <a href="https://publications.waset.org/abstracts/search?q=PLF" title=" PLF"> PLF</a>, <a href="https://publications.waset.org/abstracts/search?q=propagation" title=" propagation"> propagation</a> </p> <a href="https://publications.waset.org/abstracts/72679/off-body-sub-ghz-wireless-channel-characterization-for-dairy-cows-in-barns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">318</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> The Competitiveness of Small and Medium Sized Enterprises: Digital Transformation of Business Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chante%20Van%20Tonder">Chante Van Tonder</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Bossink"> Bart Bossink</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Schachtebeck"> Chris Schachtebeck</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecile%20Nieuwenhuizen"> Cecile Nieuwenhuizen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Small and Medium-Sized Enterprises (SMEs) play a key role in national economies around the world, being contributors to economic and social well-being. Due to this, the success, growth and competitiveness of SMEs are critical. However, there are many factors that undermine this, such as resource constraints, poor information communication infrastructure (ICT), skills shortages and poor management. The Fourth Industrial Revolution offers new tools and opportunities such as digital transformation and business model innovation (BMI) to the SME sector to enhance its competitiveness. Adopting and leveraging digital technologies such as cloud, mobile technologies, big data and analytics can significantly improve business efficiencies, value proposition and customer experiences. Digital transformation can contribute to the growth and competitiveness of SMEs. However, SMEs are lagging behind in the participation of digital transformation. Extant research lacks conceptual and empirical research on how digital transformation drives BMI and the impact it has on the growth and competitiveness of SMEs. The purpose of the study is, therefore, to close this gap by developing and empirically validating a conceptual model to determine if SMEs are achieving BMI through digital transformation and how this is impacting the growth, competitiveness and overall business performance. An empirical study is being conducted on 300 SMEs, consisting of 150 South-African and 150 Dutch SMEs, to achieve this purpose. Structural equation modeling is used, since it is a multivariate statistical analysis technique that is used to analyse structural relationships and is a suitable research method to test the hypotheses in the model. Empirical research is needed to gather more insight into how and if SMEs are digitally transformed and how BMI can be driven through digital transformation. The findings of this study can be used by SME business owners, managers and employees at all levels. The findings will indicate if digital transformation can indeed impact the growth, competitiveness and overall performance of an SME, reiterating the importance and potential benefits of adopting digital technologies. In addition, the findings will also exhibit how BMI can be achieved in light of digital transformation. This study contributes to the body of knowledge in a highly relevant and important topic in management studies by analysing the impact of digital transformation on BMI on a large number of SMEs that are distinctly different in economic and cultural factors <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20models" title="business models">business models</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20model%20innovation" title=" business model innovation"> business model innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=digital%20transformation" title=" digital transformation"> digital transformation</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a> </p> <a href="https://publications.waset.org/abstracts/139156/the-competitiveness-of-small-and-medium-sized-enterprises-digital-transformation-of-business-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139156.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">240</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Large-Scale Experimental and Numerical Studies on the Temperature Response of Main Cables and Suspenders in Bridge Fires</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shaokun%20Ge">Shaokun Ge</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20Merci"> Bart Merci</a>, <a href="https://publications.waset.org/abstracts/search?q=Fubao%20Zhou"> Fubao Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Gao%20Liu"> Gao Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ya%20Ni"> Ya Ni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates the thermal response of main cables and suspenders in suspension bridges subjected to vehicle fires, integrating large-scale gasoline pool fire experiments with numerical simulations. Focusing on a suspension bridge in China, the research examines the impact of wind speed, pool size, and lane position on flame dynamics and temperature distribution along the cables. The results indicate that higher wind speeds and larger pool sizes markedly increase the mass burning rate, causing flame deflection and non-uniform temperature distribution along the cables. Under a wind speed of 1.56 m/s, maximum temperatures reached approximately 960 ℃ near the base in emergency lane fires and 909 ℃ at 1.6 m height for slow lane fires, underscoring the heightened thermal risk from emergency lane fires. The study recommends a zoning strategy for cable fire protection, suggesting a 0-12.8 m protection zone with a target temperature of 1000 ℃ and a 12.8-20.8 m zone with a target temperature of 700 ℃, both with a 90-minute fire resistance. This approach, based on precise temperature distribution data from experimental and simulation results, provides a vital reference for the fire protection design of suspension bridge cables. Understanding cable temperature response during vehicle fires is crucial for developing fire protection systems, as it dictates necessary structural protection, fire resistance duration, and maximum temperatures for mitigation. Challenges of controlling environmental wind in large-scale fire tests are also addressed, along with a call for further research on fire behavior mechanisms and structural temperature response in cable-supported bridges under varying wind conditions. Conclusively, the proposed zoning strategy enhances the theoretical understanding of near-field temperature response in bridge fires, contributing significantly to the field by supporting the design of passive fire protection systems for bridge cables, safeguarding their integrity under extreme fire conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bridge%20fire" title="bridge fire">bridge fire</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20response" title=" temperature response"> temperature response</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale%20experiment" title=" large-scale experiment"> large-scale experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulations" title=" numerical simulations"> numerical simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20protection" title=" fire protection"> fire protection</a> </p> <a href="https://publications.waset.org/abstracts/193172/large-scale-experimental-and-numerical-studies-on-the-temperature-response-of-main-cables-and-suspenders-in-bridge-fires" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193172.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Ethical, Legal and Societal Aspects of Unmanned Aircraft in Defence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Henning%20Lahmann">Henning Lahmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Benjamyn%20I.%20Scott"> Benjamyn I.

Despite the vast opportunities that defence AI-technology presents, there are also a variety of ethical, legal, and societal concerns. To ensure the successful use of AI technology by the military, ethical, legal, and societal aspects (ELSA) need to be considered, and their concerns continuously addressed at all levels. This includes ELSA considerations during the design, manufacturing and maintenance of AI-based systems, as well as its utilisation via appropriate military doctrine and training. This raises the question how defence organisations can remain strategically competitive and at the edge of military innovation, while respecting the values of its citizens. This paper will explain the set-up and share preliminary results of a 4-year research project commissioned by the National Research Council in the Netherlands on the ethical, legal, and societal aspects of AI in defence. The project plans to develop a future-proof, independent, and consultative ecosystem for the responsible use of AI in the defence domain. In order to achieve this, the lab shall devise a context-dependent methodology that focuses on the ‘analysis’, ‘design’ and ‘evaluation’ of ELSA of AI-based applications within the military context, which include inter alia unmanned aircraft. This is bolstered as the Lab also recognises and complements the existing methods in regards to human-machine teaming, explainable algorithms, and value-sensitive design. Such methods will be modified for the military context and applied to pertinent case-studies. These case-studies include, among others, the application of autonomous robots (incl. semi- autonomous) and AI-based methods against cognitive warfare. As the perception of the application of AI in the military context, by both society and defence personnel, is important, the Lab will study how these perceptions evolve and vary in different contexts. Furthermore, the Lab will monitor – as they may influence people’s perception – developments in the global technological, military and societal spheres. Although the emphasis of the research project is on different forms of AI in defence, it focuses on several case studies. One of these case studies is on unmanned aircraft, which will also be the focus of the paper. Hence, ethical, legal, and societal aspects of unmanned aircraft in the defence domain will be discussed in detail, including but not limited to privacy issues. Typical other issues concern security (for people, objects, data or other aircraft), privacy (sensitive data, hindrance, annoyance, data collection, function creep), chilling effects, PlayStation mentality, and PTSD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20weapon%20systems" title="autonomous weapon systems">autonomous weapon systems</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aircraft" title=" unmanned aircraft"> unmanned aircraft</a>, <a href="https://publications.waset.org/abstracts/search?q=human-machine%20teaming" title=" human-machine teaming"> human-machine teaming</a>, <a href="https://publications.waset.org/abstracts/search?q=meaningful%20human%20control" title=" meaningful human control"> meaningful human control</a>, <a href="https://publications.waset.org/abstracts/search?q=value-sensitive%20design" title=" value-sensitive design"> value-sensitive design</a> </p> <a href="https://publications.waset.org/abstracts/151541/ethical-legal-and-societal-aspects-of-unmanned-aircraft-in-defence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151541.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Accuracy of Fitbit Charge 4 for Measuring Heart Rate in Parkinson’s Patients During Intense Exercise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Colonna">Giulia Colonna</a>, <a href="https://publications.waset.org/abstracts/search?q=Jocelyn%20Hoye"> Jocelyn Hoye</a>, <a href="https://publications.waset.org/abstracts/search?q=Bart%20de%20Laat"> Bart de Laat</a>, <a href="https://publications.waset.org/abstracts/search?q=Gelsina%20Stanley"> Gelsina Stanley</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Key"> Jose Key</a>, <a href="https://publications.waset.org/abstracts/search?q=Alaaddin%20Ibrahimy"> Alaaddin Ibrahimy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sule%20Tinaz"> Sule Tinaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Evan%20D.%20Morris"> Evan D. Morris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parkinson’s disease (PD) is the second most common neurodegenerative disease and affects approximately 1% of the world’s population. Increasing evidence suggests that aerobic physical exercise can be beneficial in mitigating both motor and non-motor symptoms of the disease. In a recent pilot study of the role of exercise on PD, we sought to confirm exercise intensity by monitoring heart rate (HR). For this purpose, we asked participants to wear a chest strap heart rate monitor (Polar Electro Oy, Kempele). The device sometimes proved uncomfortable. Looking forward to larger clinical trials, it would be convenient to employ a more comfortable and user friendly device. The Fitbit Charge 4 (Fitbit Inc) is a potentially comfortable, user-friendly solution since it is a wrist-worn heart rate monitor. Polar H10 has been used in large trials, and for our purposes, we treated it as the gold standard for the beat-to-beat period (R-R interval) assessment. In previous literature, it has been shown that Fitbit Charge 4 has comparable accuracy to Polar H10 in healthy subjects. It has yet to be determined if the Fitbit is as accurate as the Polar H10 in subjects with PD or in clinical populations, generally. Goal: To compare the Fitbit Charge 4 to the Polar H10 for monitoring HR in PD subjects engaging in an intensive exercise program. Methods: A total of 596 exercise sessions from 11 subjects (6 males) were collected simultaneously by both devices. Subjects with early-stage PD (Hoehn & Yahr <=2) were enrolled in a 6 months exercise training program designed for PD patients. Subjects participated in 3 one-hour exercise sessions per week. They wore both Fitbit and Polar H10 during each session. Sessions included rest, warm-up, intensive exercise, and cool-down periods. We calculated the bias in the HR via Fitbit under rest (5min) and intensive exercise (20min) by comparing the mean HR during each of the periods to the respective means measured by the Polar (HRFitbit – HRPolar). We also measured the sensitivity and specificity of Fitbit for detecting HRs that exceed the threshold for intensive exercise, defined as 70% of an individual’s theoretical maximum HR. Different types of correlation between the two devices were investigated. Results: The mean bias was 1.68 bpm at rest and 6.29 bpm during high intensity exercise, with an overestimation by Fitbit in both conditions. The mean bias of Fitbit across both rest and intensive exercise periods was 3.98 bpm. The sensitivity of the device in identifying high intensity exercise sessions was 97.14 %. The correlation between the two devices was non-linear, suggesting a saturation tendency of Fitbit to saturate at high values of HR. Conclusion: The performance of Fitbit Charge 4 is comparable to Polar H10 for assessing exercise intensity in a cohort of PD subjects. The device should be considered a reasonable replacement for the more cumbersome chest strap technology in future similar studies of clinical populations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fitbit" title="fitbit">fitbit</a>, <a href="https://publications.waset.org/abstracts/search?q=heart%20rate%20measurements" title=" heart rate measurements"> heart rate measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=parkinson%E2%80%99s%20disease" title=" parkinson’s disease"> parkinson’s disease</a>, <a href="https://publications.waset.org/abstracts/search?q=wrist-wearable%20devices" title=" wrist-wearable devices"> wrist-wearable devices</a> </p> <a href="https://publications.waset.org/abstracts/165333/accuracy-of-fitbit-charge-4-for-measuring-heart-rate-in-parkinsons-patients-during-intense-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165333.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">109</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> The Impact of Improved Grain Storage Technology on Marketing Behaviour and Livelihoods of Maize Farmers: A Randomized Controlled Trial in Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Betelhem%20M.%20Negede">Betelhem M.

Therefore, they need to use on-farm storage technologies to bridge the lean season and benefit from price arbitrage. Maize stored using traditional storage bags offer no protection from insects and molds, leading to high storage losses. In Ethiopia access to and use of modern storage technologies are still limited, restraining farmers to benefit from local maize price fluctuations. We used a randomized controlled trial among 871 maize farmers to evaluate the impacts of Purdue Improved Crop Storage (PICS) bags, also known as hermetic bags, on storage losses, and especially on behavioral changes with respect to consumption, marketing, and income among maize farmers in Ethiopia. This study builds upon the limited previous experimental research that has tried to understand farmers’ grain storage and post-harvest losses and identify mechanisms behind the persistence of these challenges. Our main hypothesis is that access to PICS bags allows farmers to increase production, storage and maize income. Also delay the length of maize storage, reduce maize post-harvest losses and improve their food security. Our results show that even though farmers received only three PICS bags that represent 10percent of their total maize stored, they delay their length of maize storage for sales by two weeks. However, we find no treatment effect on maize income, suggesting that the arbitrage of two weeks is too small. Also, we do not find any reduction in storage losses due to farmers’ reaction by selling early and by using cheap and readily available but potentially harmful storage chemicals. Looking at the heterogeneity treatment effects between the treatment variable and highland and lowland villages, we find a decrease in the percentage of maize stored by 4 percent in the highland villages. This confirms that location specific factors, such as agro-ecology and proximity to markets are important factors that influence whether and how much of the harvest a farmer stores. These findings highlight the benefits of hermetic storage bags, by allowing farmers to make inter-temporal arbitrage and by reducing potential health risks from storage chemicals. The main policy recommendation that emanates from our study is that postharvest losses reduction throughout the whole value chain is an important pathway to food and income security in Sub-Saharan Africa (SSA). However, future storage loss interventions with hermetic storage technologies should take into account the agro-ecology of the study area and quantify storage losses beyond farmers self-reported losses, such as the count and weigh method. Finally, studies on hermetic storage technologies indicate positive impacts on post-harvest losses and in improving food security, but the adoption and use of these technologies is currently still low in SSA. Therefore, future works on the scaling up of hermetic bags, should consider reasons why farmers only use PICS bags to store grains for consumption, which is usually related to a safety-first approach or due to lack of incentives (higher price from maize not treated with chemicals), and no grain quality check. <p class="card-text"><strong>Keywords:</strong> <a
