In contrast to traditional microfluidic devices with low Reynolds number, inertial microfluidics works in the intermediate Re number range which brings about several intriguing inertial effects on particle separation/focusing to meet the throughput requirement in the real-world. Geometric modifications to make channels become irregular shapes can leverage fluid inertia to create complex secondary flow for adjusting the particle equilibrium positions and thus enhance the separation resolution and throughput. Although inertial microfluidics has been extensively studied by experiments, our current understanding of its mechanisms is poor, making it extremely difficult to build rational-design guidelines for the particle focusing locations, especially for irregularly shaped microfluidic channels. Inertial particle microfluidics in irregularly shaped channels were investigated in our group. There are several fundamental issues that require us to address. One of them is about the balance between the inertial lift forces and the secondary drag forces. Also, it is critical to quantitatively describe the dependence of the life forces on particle-particle interactions in irregularly shaped channels, such as a rectangular one. To provide physical insights into the inertial microfluidics in channels of irregular shapes, in this work the immersed boundary-lattice Boltzmann method (IB-LBM) was introduced and validated to explore the transport characteristics and the underlying mechanisms of an inertial focusing single particle in a rectangular microchannel. The transport dynamics of a finitesized particle were investigated over wide ranges of Reynolds number (20 < Re < 500) and particle size. The results show that the inner equilibrium positions are more difficult to occur in the rectangular channel, which can be explained by the secondary flow caused by the presence of a finite-sized particle. Furthermore, force decoupling analysis was utilized to study the effect of each type of lift force on the inertia migration, and a theoretical model for the lateral lift force of a finite-sized particle in the rectangular channel was established. Such theoretical model can be used to provide theoretical guidance for the design and operation of inertial microfluidics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inertial%20microfluidics" title="inertial microfluidics">inertial microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20focuse" title=" particle focuse"> particle focuse</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20force" title=" life force"> life force</a>, <a href="https://publications.waset.org/abstracts/search?q=IB-LBM" title=" IB-LBM"> IB-LBM</a> </p> <a href="https://publications.waset.org/abstracts/163749/analysis-of-lift-force-in-hydrodynamic-transport-of-a-finite-sized-particle-in-inertial-microfluidics-with-a-rectangular-microchannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163749.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">71</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">3151</span> Fabrication of Highly-Ordered Interconnected Porous Polymeric Particles and Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Alroaithi">Mohammad Alroaithi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Porous polymeric materials have attracted a great attention due to their distinctive porous structure within a polymer matrix. They are characterised by the presence of external pores on the surface as well as inner interconnected windows. Conventional techniques to produce porous polymeric materials encounters major challenge in controlling the properties of the resultant structures including morphology, pores, cavities size, and porosity. Herein, we present a facile and versatile microfluidics technique for the fabrication of uniform porous polymeric structures with highly ordered and well-defined interconnected windows. The shapes of the porous structures can either be a microparticles or foam. Both shapes used microfluidics platform to first produce monodisperse emulsion. The uniform emulsions, were then consolidated into porous structures through UV photopolymerisation. The morphology, pores, cavities size, and porosity of the structures can be precisely manipulated by the flowrate. The proposed strategy might provide a key advantage for fabrication of uniform porous materials over many existing technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer" title="polymer">polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20particles" title=" porous particles"> porous particles</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20structures" title=" porous structures"> porous structures</a> </p> <a href="https://publications.waset.org/abstracts/84709/fabrication-of-highly-ordered-interconnected-porous-polymeric-particles-and-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84709.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">186</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">3150</span> A Case Study of Open Source Development Practices within a Large Company Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alma%20Orucevic-Alagic">Alma Orucevic-Alagic</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20H%C3%B6st"> Martin Höst</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open source communities have demonstrated that complex and enterprise grade software can be produced, supported, and maintained by self-organizing groups of developers using primarily electronic form of communication. Due to the inherent nature of open source development, a specific set of open source software development practices has evolved. While there is an ongoing research on the topic of applicability of open source development practices within a company setting, still little is known about their benefits and challenges. The objective of this research is to understand if and to what degree open source development practices observed within a mature open source community are aligned with development practices within a large software and hardware company setting. For the purpose of this case study a set of open source development practices that are present in a mature open source community has been identified. Then, development practices of a large, international, hardware and software company based in Sweden were assessed and compared to the identified open source community practices. It is shown that there are many similarities between a mature open source community and a large company setting in regard to software development practices. We also identify practices that exist in open source communities and that are not standard within a company setting, but whose implementation can result in an improved software development efficiency within the company setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development%20practices" title="development practices">development practices</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software" title=" open source software"> open source software</a>, <a href="https://publications.waset.org/abstracts/search?q=innersource" title=" innersource"> innersource</a>, <a href="https://publications.waset.org/abstracts/search?q=closed%20open%20source" title=" closed open source"> closed open source</a> </p> <a href="https://publications.waset.org/abstracts/13154/a-case-study-of-open-source-development-practices-within-a-large-company-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13154.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">558</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">3149</span> Author Self-Archiving in Open Access Institutional Repositories for Awareness Creation in Universities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwame%20Kodua-Ntim">Kwame Kodua-Ntim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study explored the authors self-archiving to create awareness of open-access institutional repositories in universities. The qualitative approach of the study was informed by the interpretive paradigm as well as the case research design. The target population for the study was all twelve (12) open-access institutional repositories managers and administrators purposively selected from the five (5) universities in Ghana. The universities were chosen since they were the only ones listed in the Directory of Open Access Repositories. Interviews were conducted using a semi-structured interview guide and data were analyzed using thematic analysis. The study revealed that academics had some information about self-archiving in open-access institutional repositories and university libraries with open-access institutional repositories were using DSpace software. Managers and administrators of open-access institutional repositories mediated content uploaded and believed that author self-archiving could improve awareness of open-access institutional repositories. The study recommended that universities should fully implement the author’s self-archiving protocol, and academics should be trained to be able to upload research works onto open-access institutional repositories. Furthermore, the university and university library should provide rigorous policies on author self-archiving and incentives for author self-archiving in the open access institutional repositories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=author" title="author">author</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20repositories" title=" institutional repositories"> institutional repositories</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access" title=" open access"> open access</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20archive" title=" open archive"> open archive</a>, <a href="https://publications.waset.org/abstracts/search?q=self-archiving" title=" self-archiving"> self-archiving</a> </p> <a href="https://publications.waset.org/abstracts/161785/author-self-archiving-in-open-access-institutional-repositories-for-awareness-creation-in-universities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161785.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">87</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">3148</span> A Fluid-Walled Microfluidic Device for Cell Migration Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cyril%20Deroy">Cyril Deroy</a>, <a href="https://publications.waset.org/abstracts/search?q=Agata%20Rumianek"> Agata Rumianek</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20R.%20Greaves"> David R.

Walsh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various microfluidic platforms have been developed in the past couple of decades offering experimental methods for the study of cell migration; however, their implementation in the laboratory has remained limited. Some reasons cited for the lack of uptake include the technical complexity of the devices, high failure rate associated with gas-bubbles, biocompatibility concerns with the use of polydimethylsiloxane (PDMS) and equipment/time/expertise requirements for operation and manufacture. As sample handling remains challenging due to the closed format of microfluidic devices, open microfluidic systems have been developed offering versatility and simplicity of use. Rather than confining fluids by solid walls, samples can be accessed directly over the open platform, by removing at least one of the solid boundaries, such as the cover. In this paper, a method for the fabrication of open fluid-walled microfluidic circuits for cell migration studies is introduced, where only materials commonly used by the life-science community are required; tissue culture dishes and cell media. The simplicity of the method, and ability to retrieve cells of interest are two key features of the method. Both passive and active flow-devices can be created in this way. To demonstrate the versatility of the method a cell migration assay is performed, which requires fabricating circuits for establishing chemical gradients, loading cells and incubating, creating chemical gradients, real time imaging of cell migration and finally retrieval of cells. The open architecture has high fidelity as it eliminates air bubble related failures and enables the precise control of gradients. The ability to fabricate custom microfluidic designs in minutes should make this method suitable for use in a wide range of cell migration studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemotaxis" title="chemotaxis">chemotaxis</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20walls" title=" fluid walls"> fluid walls</a>, <a href="https://publications.waset.org/abstracts/search?q=gradient%20generation" title=" gradient generation"> gradient generation</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20microfluidics" title=" open microfluidics"> open microfluidics</a> </p> <a href="https://publications.waset.org/abstracts/100370/a-fluid-walled-microfluidic-device-for-cell-migration-studies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100370.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">149</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">3147</span> Sheathless, Viscoelastic Circulating Tumor Cell Separation Using Closed-Loop Microfluidics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyunjung%20Lim">Hyunjung Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeonghun%20Nam"> Jeonghun Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyuk%20Choi"> Hyuk Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-throughput separation is an essential technique for cancer research and diagnosis. Here, we propose a viscoelastic microfluidic device for sheathless, high-throughput isolation of circulating tumor cells (CTCs) from white blood cells. Here, we demonstrate a viscoelastic method for separation and concentration of CTCs using closed-loop microfluidics. Our device is a rectangular straight channel with a low aspect ratio. Also, to achieve high-efficiency, high-throughput processing, we used a polymer solution with low viscosity. At the inlet, CTCs and white blood cells (WBCs) were randomly injected into the microchannel. Due to the viscoelasticity-induced lateral migration to the equilibrium positions, large CTCs could be collected from the side outlet while small WBCs were removed at the center outlet. By recirculating the collected CTCs from the side outlet back to the sample reservoir, continuous separation and concentration of CTCs could be achieved with high separation efficiency (~ 99%). We believe that our device has the potential to be applied in resource-limited clinical settings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circulating%20tumor%20cell" title="circulating tumor cell">circulating tumor cell</a>, <a href="https://publications.waset.org/abstracts/search?q=closed-loop%20microfluidics" title=" closed-loop microfluidics"> closed-loop microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=concentration" title=" concentration"> concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=separation" title=" separation"> separation</a>, <a href="https://publications.waset.org/abstracts/search?q=viscoelastic%20fluid" title=" viscoelastic fluid"> viscoelastic fluid</a> </p> <a href="https://publications.waset.org/abstracts/90891/sheathless-viscoelastic-circulating-tumor-cell-separation-using-closed-loop-microfluidics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90891.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">153</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">3146</span> Development of Colorimetric Based Microfluidic Platform for Quantification of Fluid Contaminants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sangeeta%20Palekar">Sangeeta Palekar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahima%20Rana"> Mahima Rana</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayu%20Kalambe"> Jayu Kalambe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a microfluidic-based platform for the quantification of contaminants in the water is proposed. The proposed system uses microfluidic channels with an embedded environment for contaminants detection in water. Microfluidics-based platforms present an evident stage of innovation for fluid analysis, with different applications advancing minimal efforts and simplicity of fabrication. Polydimethylsiloxane (PDMS)-based microfluidics channel is fabricated using a soft lithography technique. Vertical and horizontal connections for fluid dispensing with the microfluidic channel are explored. The principle of colorimetry, which incorporates the use of Griess reagent for the detection of nitrite, has been adopted. Nitrite has high water solubility and water retention, due to which it has a greater potential to stay in groundwater, endangering aquatic life along with human health, hence taken as a case study in this work. The developed platform also compares the detection methodology, containing photodetectors for measuring absorbance and image sensors for measuring color change for quantification of contaminants like nitrite in water. The utilization of image processing techniques offers the advantage of operational flexibility, as the same system can be used to identify other contaminants present in water by introducing minor software changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorimetric" title="colorimetric">colorimetric</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20contaminants" title=" fluid contaminants"> fluid contaminants</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrite%20detection" title=" nitrite detection"> nitrite detection</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a> </p> <a href="https://publications.waset.org/abstracts/141028/development-of-colorimetric-based-microfluidic-platform-for-quantification-of-fluid-contaminants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141028.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">198</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">3145</span> Impact of Schools' Open and Semi-Open Spaces on Student's Studying Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chaithanya%20Pothuganti">Chaithanya Pothuganti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open and semi-open spaces in educational buildings like corridors, mid landings, seating spaces, lobby, courtyards are traditionally have been the places of social communion and interaction which helps in promoting the knowledge, performance, activeness, and motivation in students.

The core objective of this paper is to find the level of impact on student learning behavior and to identify the suitable proportions and configuration of spaces that shape the schools. In order to achieve this, different types of open spaces in schools and their impact on student’s performance in various existing models are analysed using case studies to draw some design principles. The study is limited to indoor open spaces like corridors, break out spaces and courtyards. The expected outcome of the paper is to suggest better design considerations for the development of semi-open and open spaces which functions as an element for informal learnings. Its focus is to provide further thinking on designing and development of open spaces in educational buildings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=configuration%20of%20spaces%20and%20proportions" title="configuration of spaces and proportions">configuration of spaces and proportions</a>, <a href="https://publications.waset.org/abstracts/search?q=informal%20learning" title=" informal learning"> informal learning</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20spaces" title=" open spaces"> open spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=schools" title=" schools"> schools</a>, <a href="https://publications.waset.org/abstracts/search?q=student%E2%80%99s%20behavior" title=" student’s behavior"> student’s behavior</a> </p> <a href="https://publications.waset.org/abstracts/82053/impact-of-schools-open-and-semi-open-spaces-on-students-studying-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82053.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">309</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">3144</span> Open Minds but Closed Access: Why Are There so Few Gold Open Access LIS Journals And Why Are so Many Librarians Unwilling to Unlock Their Scholarship?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Baker">Sarah Baker</a>, <a href="https://publications.waset.org/abstracts/search?q=Jayati%20Chaudhuri"> Jayati Chaudhuri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Librarians have embraced the open access movement in all disciplines but their own. They are strong advocates on college campuses and curate institutional repositories, yet there are surprisingly few open access LIS journals. Presenters evaluated the open access availability of library and information science literature. After analyzing the top 100 library science journals (the top 50 journals from Scimago and JCR) and finding very few gold open access journals, they then investigated the availability of open access articles from the top 10 closed access journals. Presenters would like to generate a conversation on what type of proactive approach librarians can take to increase open access to literature within our discipline. Librarians like their colleagues in other disciplines are not motivated to submit their articles to their institutional repositories. Presenters have found a similar reluctance from their fellow colleagues regarding open access initiatives on campus. Presenters will describe Open Access Week activities as part of a campus-wide initiative and share some faculty comments, concerns, and misconceptions that came up as a part of this dialog. Presenters will discuss their personal experiences providing access to faculty publications through the California State University Los Angeles institutional repository. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=faculty%20scholarship" title="faculty scholarship">faculty scholarship</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20repositories" title=" institutional repositories"> institutional repositories</a>, <a href="https://publications.waset.org/abstracts/search?q=library%20and%20information%20science%20journals" title=" library and information science journals"> library and information science journals</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20access" title=" open access"> open access</a> </p> <a href="https://publications.waset.org/abstracts/26157/open-minds-but-closed-access-why-are-there-so-few-gold-open-access-lis-journals-and-why-are-so-many-librarians-unwilling-to-unlock-their-scholarship" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26157.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">331</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">3143</span> Open educational Resources' Metadata: Towards the First Star to Quality of Open Educational Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Audrey%20Romero-Pelaez">Audrey Romero-Pelaez</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Carlos%20Morocho-Yunga"> Juan Carlos Morocho-Yunga</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing amount of open educational resources (OER) published on the web for consumption in teaching and learning environments also generates a growing need to ensure the quality of these resources. The low level of OER discovery is one of the most significant drawbacks when faced with its reuse, and as a consequence, high-quality educational resources can go unnoticed. Metadata enables the discovery of resources on the web. The purpose of this study is to lay the foundations for open educational resources to achieve their first quality star within the Quality4OER Framework.

While open-source software development is becoming more important, the software development processes are often not as structured as corporate software development processes. Papers show that communities, creating open-source software, often lack structure and documentation. However, most recent studies about this topic are often ten or more years old. Therefore, this research has been conducted to determine if the lack of structure and documentation in requirement engineering is currently still the situation in these communities. Three open-source products have been chosen as subjects for conducting this research. The data for this research was gathered based on interviews, observations, and analyses of feature proposals and issue tracking tools. In this paper, we present a comparison and an analysis of the different methods used for requirements documentation to understand the current practices of requirements documentation in open source software development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20study" title="case study">case study</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software" title=" open source software"> open source software</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software%20development" title=" open source software development"> open source software development</a>, <a href="https://publications.waset.org/abstracts/search?q=requirement%20elicitation" title=" requirement elicitation"> requirement elicitation</a>, <a href="https://publications.waset.org/abstracts/search?q=requirement%20engineering" title=" requirement engineering"> requirement engineering</a> </p> <a href="https://publications.waset.org/abstracts/143917/requirement-engineering-within-open-source-software-development-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143917.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">103</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">3141</span> Open Consent And Artificial Intelligence For Health Research in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amy%20Gooden">Amy Gooden</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various modes of consent have been utilized in health research, but open consent has not been explored in South Africa’s AI research context.

Many governments pursued many anti-corruption reforms and have created a system of checks and balances. Three types of corruption are faced by citizens; administrative corruption, collusion and extortion. Accountability is one of the benchmarks for building transparent government. The public sector is required to report the results of the programs that have been implemented so that the citizen can judge whether the institution has been working such as economical, efficient and effective. Open Data is offering solutions for the implementation of good governance in organizations who want to be more transparent. In addition, Open Data can create transparency and accountability to the community. The objective of this paper is to build a framework of open data for accountability to combating corruption. This paper will investigate the relationship between open data, and accountability as part of anti-corruption initiatives. This research will investigate the impact of open data implementation on public organization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20data" title="open data">open data</a>, <a href="https://publications.waset.org/abstracts/search?q=accountability" title=" accountability"> accountability</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-corruption" title=" anti-corruption"> anti-corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=framework" title=" framework"> framework</a> </p> <a href="https://publications.waset.org/abstracts/62083/towards-a-framework-for-using-open-data-for-accountability-a-case-study-of-a-program-to-reduce-corruption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62083.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">336</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">3139</span> Open Innovation Strategy (OIS) Paradigm and an OIS Capabilities Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anastasis%20D.%20Petrou">Anastasis D.

Yet, a number of stumbling blocks in the form of closed innovation principles weaved into the fabric of a traditional business model stand in the way of the new paradigm’s momentum to increase value in various business contexts. The paper argues that businesses considering an engagement with the open innovation paradigm would need to take steps to improve their multiplicative, absorptive and relational capabilities, respectively. The needed improvements would amount to a business model evolutionary transformation and eventually bring about a paradigm overhaul in business. The transformation is worth staging over time to ensure that open innovation is developed across interconnected and partnered areas of strategic importance.

Education levels of poly house farmers are high compared to open field farmers, where 57.14% poly house farmers are high school educated, whereas 35% open field farmers are illiterates. Majority farmers use nursery of 35 days and grow in <0.5 acre poly house in summer and rabi and < 1 acre in open field during kharif. Awareness on pesticide related issues is varying among poly house and open field farmers with some commonality, where 28.57% poly house farmers know about recommended pesticides while only 10% open field farmers are aware of this issue. However, in general, all farmers contact pesticide dealer for recommendations, poly house farmers prefer to contact scientists (35.71%) and open field farmers prefer to contact agricultural officers (33.33). Most farmers are unaware about pesticide classification and toxicity symbols on packing. Farmers are aware about endosulfan ban, but only 21.42% poly house and 11.66% open field farmers know about ban of monocrotofos on vegetables. Very few farmers know about pesticide residues and related issues, but know washing helps to reduce contamination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=open%20field" title="open field">open field</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide%20usage" title=" pesticide usage"> pesticide usage</a>, <a href="https://publications.waset.org/abstracts/search?q=polyhouses" title=" polyhouses"> polyhouses</a>, <a href="https://publications.waset.org/abstracts/search?q=residues%20survey" title=" residues survey"> residues survey</a> </p> <a href="https://publications.waset.org/abstracts/21476/studies-on-pesticide-usage-pattern-and-farmers-knowledge-on-pesticide-usage-and-technologies-in-open-field-and-poly-house-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21476.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">468</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">3137</span> The Impact of Public Open Space System on Housing Price in Chicago</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Si%20Chen">Si Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Le%20Zhang"> Le Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xian%20He"> Xian He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research explored the influences of public open space system on housing price through hedonic models, in order to support better open space plans and economic policies. We have three initial hypotheses: 1) public open space system has an overall positive influence on surrounding housing prices. 2) Different public open space types have different levels of influence on motivating surrounding housing prices. 3) Walking and driving accessibilities from property to public open spaces have different statistical relation with housing prices. Cook County, Illinois, was chosen to be a study area since data availability, sufficient open space types, and long-term open space preservation strategies. We considered the housing attributes, driving and walking accessibility scores from houses to nearby public open spaces, and driving accessibility scores to hospitals as influential features and used real housing sales price in 2010 as a dependent variable in the built hedonic model. Through ordinary least squares (OLS) regression analysis, General Moran’s I analysis and geographically weighted regression analysis, we observed the statistical relations between public open spaces and housing sale prices in the three built hedonic models and confirmed all three hypotheses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hedonic%20model" title="hedonic model">hedonic model</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20open%20space" title=" public open space"> public open space</a>, <a href="https://publications.waset.org/abstracts/search?q=housing%20sale%20price" title=" housing sale price"> housing sale price</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20analysis" title=" regression analysis"> regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=accessibility%20score" title=" accessibility score"> accessibility score</a> </p> <a href="https://publications.waset.org/abstracts/114572/the-impact-of-public-open-space-system-on-housing-price-in-chicago" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114572.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">133</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">3136</span> Rigorous Literature Review: Open Science Policy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20T.%20Svahn">E.

It also presents what policy needs are persistent to enable safe and effective dissemination of scientific knowledge. This information may be of interest to open science and science policy makers globally, especially in the view of recent adoption of supranational open science policies such as Plan S. Evaluation of open science policy landscape is in pressing need of assessment regarding its impact on the research community and society at wide as no previous literature review has been conducted on the topic. This study is a rigorous literature review based on constructivist grounded theory method on the full body of scientific open science policy publications. Selection of these articles has been conducted in 2019 and 2020 in major global knowledge databases. Through the analysis of these articles, two key themes emerged that are seen to shape the relationship between science and society. 1st is that of the policy enabling open science in a safe and effective way, and 2nd is that of the outcome of the science policy may have on the research community and the wider society. These findings accentuate that open science policies can have a major impact on not only research process and availability of knowledge but also on society itself. As an outcome of this study, a theoretical framework is constructed, and the need for further study on open science policy itself on a higher level becomes apparent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructivist%20grounded%20theory" title="constructivist grounded theory">constructivist grounded theory</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20science%20policy" title=" open science policy"> open science policy</a>, <a href="https://publications.waset.org/abstracts/search?q=rigorous%20literature%20review" title=" rigorous literature review"> rigorous literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20policy" title=" science policy"> science policy</a> </p> <a href="https://publications.waset.org/abstracts/126920/rigorous-literature-review-open-science-policy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126920.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">167</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">3135</span> Study of the Landslide and Stability of Open Pit Quarry: Case of Open Pite Quarry of Chouf Amar M'sila, Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saadoun%20Abd%20Errazak">Saadoun Abd Errazak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafssaoui%20Abdallah"> Hafssaoui Abdallah</a>, <a href="https://publications.waset.org/abstracts/search?q=Fredj%20Mohamed"> Fredj Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mining operations open induce risks of instability that can cause landslides and collapse at the bleachers slope. These risks may occur both during and after the operation phase. The magnitude of these risks depends on the mechanical and physical characteristics of the rock mass, the geometrical dimensions of ore bodies, their spatial arrangement, and the state of the operated area. If security and technology measures are not taken into account for this purpose, the environment will be affected. The main objective of this work is to assess these risks by analytical and numerical methods.

With a specific focus on the Action Plan DPN6 and DPN9, ex-landfill redevelopment needs and provision of open space are detailed to identify their potential and constraints in the development of sustainable cities. As a result, this paper found a link between the needs of urban ex-landfill redevelopment and approach to provide adequate urban open space. Through the proposal of the development of public park at urban ex-landfill sites, the needs of ex-landfill redevelopment and the adequacy of urban open space provision is being 'united' and translated as an approach to create a sustainable urban development in Malaysia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ex-landfill%20redevelopment" title="ex-landfill redevelopment">ex-landfill redevelopment</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20spaces" title=" open spaces"> open spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=National%20Urban%20Policy" title=" National Urban Policy"> National Urban Policy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20urban%20development" title=" sustainable urban development"> sustainable urban development</a> </p> <a href="https://publications.waset.org/abstracts/9326/translating-ex-landfill-development-needs-and-adequacy-of-open-space-provision-in-malaysian-urban-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9326.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">455</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">3133</span> Combined Influence of Charge Carrier Density and Temperature on Open-Circuit Voltage in Bulk Heterojunction Organic Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Douglas%20Yeboah">Douglas Yeboah</a>, <a href="https://publications.waset.org/abstracts/search?q=Monishka%20Narayan"> Monishka Narayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Jai%20Singh"> Jai Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the key parameters in determining the power conversion efficiency (PCE) of organic solar cells (OSCs) is the open-circuit voltage, however, it is still not well understood. In order to examine the performance of OSCs, it is necessary to understand the losses associated with the open-circuit voltage and how best it can be improved. Here, an analytical expression for the open-circuit voltage of bulk heterojunction (BHJ) OSCs is derived from the charge carrier densities without considering the drift-diffusion current. The open-circuit voltage thus obtained is dependent on the donor-acceptor band gap, the energy difference between the highest occupied molecular orbital (HOMO) and the hole quasi-Fermi level of the donor material, temperature, the carrier density (electrons), the generation rate of free charge carriers and the bimolecular recombination coefficient. It is found that open-circuit voltage increases when the carrier density increases and when the temperature decreases. The calculated results are discussed in view of experimental results and agree with them reasonably well. Overall, this work proposes an alternative pathway for improving the open-circuit voltage in BHJ OSCs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charge%20carrier%20density" title="charge carrier density">charge carrier density</a>, <a href="https://publications.waset.org/abstracts/search?q=open-circuit%20voltage" title=" open-circuit voltage"> open-circuit voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solar%20cells" title=" organic solar cells"> organic solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/68927/combined-influence-of-charge-carrier-density-and-temperature-on-open-circuit-voltage-in-bulk-heterojunction-organic-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68927.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">373</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">3132</span> The Potential of Public Open Space to Promote Sustainable Transportation and Reduce Dependence on Cars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farnoosh%20Faal">Farnoosh Faal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The excessive reliance on private cars has led to a range of problems, such as traffic congestion, air pollution, and carbon emissions, which have significant impacts on public health and the environment. Public open spaces have the potential to promote sustainable transportation and reduce dependence on cars by providing alternative mobility options, including walking, cycling, and public transit. This paper examines the existing research on the relationship between public open spaces and sustainable transportation. It discusses the key design principles and planning strategies that can enhance the accessibility and safety of public open spaces, particularly for pedestrians and cyclists. The paper also explores the role of public open spaces in promoting active mobility and reducing car use in urban and suburban contexts. Finally, the paper highlights the policy and institutional barriers that hinder the integration of public open spaces with sustainable transportation systems and suggests some potential solutions to overcome these barriers. Overall, the paper argues that public open spaces have immense potential to facilitate sustainable transportation and reduce car dependence, and therefore, it is important to prioritize the development and maintenance of public open spaces as a key component of sustainable urban and regional planning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20open%20space" title="public open space">public open space</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20transportation" title=" sustainable transportation"> sustainable transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=active%20mobility" title=" active mobility"> active mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20dependence" title=" car dependence"> car dependence</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20and%20regional%20planning" title=" urban and regional planning"> urban and regional planning</a>, <a href="https://publications.waset.org/abstracts/search?q=traffic%20congestion" title=" traffic congestion"> traffic congestion</a> </p> <a href="https://publications.waset.org/abstracts/163451/the-potential-of-public-open-space-to-promote-sustainable-transportation-and-reduce-dependence-on-cars" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163451.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">3131</span> Development of Open Source Geospatial Certification Model Based on Geospatial Technology Competency Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanzeel%20Ur%20Rehman%20Khan">Tanzeel Ur Rehman Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Franz%20Josef%20Behr"> Franz Josef Behr</a>, <a href="https://publications.waset.org/abstracts/search?q=Phillip%20Davis"> Phillip Davis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open source geospatial certifications are needed in geospatial technology education and industry sector. In parallel with proprietary software, free and open source software solutions become important in geospatial technology research and play an important role for the growth of the geospatial industry. ESRI, GISCI (GIS Certification Institute), ASPRS (American Society of Photogrammetry and remote sensing), and Meta spatial are offering certifications on proprietary and open source software. These are portfolio and competency based certifications depending on GIS Body of Knowledge (Bok). The analysis of these certification approaches might lead to the discovery of some gaps in them and will open a new way to develop certifications related to the geospatial open source (OS). This new certification will investigate the different geospatial competencies according to open source tools that help to identify geospatial professionals and strengthen the geospatial academic content. The goal of this research is to introduce a geospatial certification model based on geospatial technology competency model (GTCM).The developed certification will not only incorporate the importance of geospatial education and production of the geospatial competency-based workforce in universities and companies (private or public) as well as describe open source solutions with tools and technology. Job analysis, market analysis, survey analysis of this certification opens a new horizon for business as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geospatial%20certification" title="geospatial certification">geospatial certification</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source" title=" open source"> open source</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20technology%20competency%20model" title=" geospatial technology competency model"> geospatial technology competency model</a>, <a href="https://publications.waset.org/abstracts/search?q=geoscience" title=" geoscience"> geoscience</a> </p> <a href="https://publications.waset.org/abstracts/33486/development-of-open-source-geospatial-certification-model-based-on-geospatial-technology-competency-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33486.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">566</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">3130</span> Design of Open Framework Based Smart ESS Profile for PV-ESS and UPS-ESS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Young-Su%20Ryu">Young-Su Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Won-Gi%20Jeon"> Won-Gi Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Byoung-Chul%20Song"> Byoung-Chul Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hong%20Park"> Jae-Hong Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Ki-Won%20Kwon"> Ki-Won Kwon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, an open framework based smart energy storage system (ESS) profile for photovoltaic (PV)-ESS and uninterruptible power supply (UPS)-ESS is proposed and designed.

This study assessed the challenges of academic quality in the open and distance learning (ODL) education in Nigeria using Distance Learning Institute (DLI), University of Lagos and National Open University of Nigeria as a case. In carrying out the study, a descriptive survey research design was employed. A researcher-designed and validated questionnaire was used to elicit responses that translated to the quantitative data for this study. The sample comprised 665 students of the Distance Learning Institute (DLI), and National Open University of Nigeria (NOUN), carefully selected through the method of simple random sampling. Data collected from the study were analyzed using Chi-Square (X2) at 0.05 Level of significance. The results of the analysis revealed that; the use of ICT tools is a factor in ensuring quality in the Open and Distance Learning (ODL) operations; the quality of the materials made available to ODL students will determine the quality of education that will be received by the students; and the time scheduled for students for self-study, online lecturing/interaction and face to face study and the quality of education in Open and Distance Learning Institutions has a lot of impact on the quality of education the students receive.

A total of 300 household adult samples are randomly selected to study both quantitatively and qualitatively the vulnerability of malaria. On the basis of the response, the problem uncommon with groups was identified as the outdoor routine, particularly open defecation, with which the samples needed to be stratified into two major groups; users of toilets 21 and those who practice open defecation 279. Open defecation, as the habit-based vulnerability, is measured with the Pearson correlation coefficient to estimate the relationship between malaria and open defecation. It is also verified from the literature that plant fluids provide mosquitoes not only with energy but also with nutrition, to the extent that they can develop fertile eggs. In the endemic areas, the bushy Presopis Juliflora, which naturally serves as a feeding and resting spot for mosquitoes, serves as a cover to practice open defecation as well. Eventually, those who get resort to Presopis for open defecation have a higher chance of getting exposed to mosquito bites and being infected with malaria. The study concludes that the combination of bushy Prosopis Juliflora and open defecation leaves the place perpetually vulnerable to malaria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malaria" title="Malaria">Malaria</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20defecation" title=" open defecation"> open defecation</a>, <a href="https://publications.waset.org/abstracts/search?q=endemic" title=" endemic"> endemic</a>, <a href="https://publications.waset.org/abstracts/search?q=presopis%20juliflora" title=" presopis juliflora"> presopis juliflora</a> </p> <a href="https://publications.waset.org/abstracts/157104/malaria-and-environmental-sanitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157104.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">100</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">3127</span> Evaluation of Japanese Kyoto Park in Terms of User Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ruhug%C3%BCl%20%C3%96zge%20Gemici">Ruhugül Özge Gemici</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The need for open space, which is an important problem especially since the 19th century, has become more important in today's conditions.

In this work, we propose a simplified Bulk acoustophoretic system that can be used for size dependent particle sorting. A Finite Element Method (FEM) based analytical model has been developed to study the dependence of particle sizes on channel parameters, and the sorting efficiency in a given fluid medium. Based on the results, the microfluidic system has been designed to take into account all the variables involved with the underlying physics, and has been fabricated using an additive manufacturing technique employing a commercial 3D printer, to generate a simple, cost-effective system that can be used for size sensitive particle sorting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20microfluidic%20chip" title=" 3D microfluidic chip"> 3D microfluidic chip</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustophoresis" title=" acoustophoresis"> acoustophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20separation" title=" cell separation"> cell separation</a>, <a href="https://publications.waset.org/abstracts/search?q=MEMS%20%28Microelectromechanical%20Systems%29" title=" MEMS (Microelectromechanical Systems)"> MEMS (Microelectromechanical Systems)</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidics" title=" microfluidics"> microfluidics</a> </p> <a href="https://publications.waset.org/abstracts/83336/a-simplified-fabrication-friendly-acoustophoretic-model-for-size-sensitive-particle-sorting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83336.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">171</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">3124</span> Experimental Study of Discharge with Sharp-Crested Weirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Keramaris">E.

For this reason a series of laboratory experiments were performed in an open channel with a sharp-crested weir. The maximum head expected over the weir, the total upstream water height and the downstream water height of the impact in the constant bed of the open channel were measured. The discharge was measured using a tank put right after the open channel. In addition, the discharge and the upstream velocity were also calculated using already known equations. The main finding is that the relative error percentage for the majority of the experimental measurements is ± 4%, meaning that the calculation of the discharge with a sharp-crested weir gives very good results compared to the numerical results from known equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sharp-crested%20weir"
