The design of the handle is based on ergonomic principles and tries to avoid awkward postures for surgeons. The handle combines the so-called power-grip and accurate-grip in order to provide strength and accuracy in the performance of surgery. The handle is tested using both objective and subjective approaches. The objective approach uses motion capture techniques to obtain the angles of forearm, arm, wrist and hand. The muscular effort is obtained with electromyography electrodes. On the other hand, a subjective survey has been carried out using questionnaires. Results confirm that the handle is preferred by the majority of the surgeons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laparoscopic%20surgery" title="laparoscopic surgery">laparoscopic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=ergonomics" title=" ergonomics"> ergonomics</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20design" title=" mechanical design"> mechanical design</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a> </p> <a href="https://publications.waset.org/abstracts/41496/an-ergonomic-handle-design-for-instruments-in-laparoscopic-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41496.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">502</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">46</span> Estimation of the Curve Number and Runoff Height Using the Arc CN-Runoff Tool in Sartang Ramon Watershed in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.Jowkar.%20M.Samiee">L.Jowkar.

In this study, the ArcCN-Runoff rain-runoff modeling tool was used to estimate the spatial variability of the rainfall-runoff relationship in Sartang Ramon in Jiroft watershed. In this study, the runoff was estimated from 6-hour rainfall. The results showed that based on hydrological soil group map, soils with hydrological groups A, B, C, and D covered 1, 2, 55, and 41% of the basin, respectively. Given that the majority of the area has a slope above 60 percent and results of soil hydrologic groups, one can conclude that Sartang Ramon Basin has a relatively high potential for producing runoff. The average runoff height for a 6-hour rainfall with a 2-year return period is 26.6 mm. The volume of runoff from the 2-year return period was calculated as the runoff height of each polygon multiplied by the area of the polygon, which is 137913486 m³ for the whole basin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arc%20CN-Run%20off" title="Arc CN-Run off">Arc CN-Run off</a>, <a href="https://publications.waset.org/abstracts/search?q=rain-runoff" title=" rain-runoff"> rain-runoff</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20period" title=" return period"> return period</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed" title=" watershed"> watershed</a> </p> <a href="https://publications.waset.org/abstracts/121495/estimation-of-the-curve-number-and-runoff-height-using-the-arc-cn-runoff-tool-in-sartang-ramon-watershed-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121495.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">127</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">45</span> Comparative Analysis between Corn and Ramon (Brosimum alicastrum) Starches to Be Used as Sustainable Bio-Based Plastics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20R.%20R%C3%ADos-Soberanis">C.

Finding new uses for agricultural commodities is also an important area of research. Therefore, it is crucial to get new sources of natural materials that can be used in different applications. Ramon tree (Brosimum alicastrum) is a tropical plant that grows freely in Yucatan countryside. This paper focuses on the seeds recollection, processing and starch extraction and characterization in order to find out about its suitability as biomaterial. Results demonstrated that it has a high content of qualities to be used not only as comestible but also as an important component in polymeric blends. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title="biomaterials">biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization%20techniques" title=" characterization techniques"> characterization techniques</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20resource" title=" natural resource"> natural resource</a>, <a href="https://publications.waset.org/abstracts/search?q=starch" title=" starch"> starch</a> </p> <a href="https://publications.waset.org/abstracts/42740/comparative-analysis-between-corn-and-ramon-brosimum-alicastrum-starches-to-be-used-as-sustainable-bio-based-plastics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42740.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">325</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">44</span> Physiological Action of Anthraquinone-Containing Preparations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dmitry%20Yu.%20Korulkin">Dmitry Yu.

Recent studies have confirmed the addition of natural resins extracted from the bark of trees, of which Brosium alicastrum (Ramon) has been the most evaluated, besides being one of the most abundant species in the vicinity of the archaeological sites, like that Manilkara Zapota (Chicozapote). Therefore, the objective is to determine if these resins are capable of being employed in archaeological restoration. This study shows the results of the chemical composition and physical-mechanical behavior of mortar mixtures eight made with commercial lime and off by hand, calcium sand, resins added with Brosium alicastrum (Ramon) and Manilkara zapota (Chicozapote), where determined and quantified properties and chemical composition of the resins by X-Ray Fluorescence (XRF), the pH of the material was determined, indicating that both resins are acidic (3.78 and 4.02), and the addition rate maximum was obtained from resins in water by means of ultrasonic baths pulses, being in the case of 10% Manilkara zapota, because it contains up to 40% rubber and for 40% alicastrum Brosium contain less rubber. Through quantitative methodology, the compressive strength 96 specimens of 5 cm x 5 cm x 5 cm of mortar binding, 72 with partial substitution of water mixed with natural resins in proportions 5 to 10% in the case was evaluated of Manilkara Zapota, for Brosium alicastrum 20 and 40%, and 12 artificial resin and 12 without additive (mortars witnesses). 24 specimens likewise glued brick with mortar, for testing shear adhesion was found where, then the microstructure more conducive additions was determined by SEM analysis were prepared sweep. The test results indicate that the addition Manilkara zapota resin in the proportion of 10% 1.5% increase in compressive strength and 1% with respect to adhesion, compared to the control without addition mortar; In the case of Brosium alicastrum results show that compressive strengths and adhesion were insignificant compared to those made with registered by Manilkara zapota mixtures. Mortars containing the natural resins have improvements in physical properties and increase the mechanical strength and adhesion, compared to those who do not, in addition to the components are chemically compatible, therefore have considered that can be employed in Archaeological restoration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lime" title="lime">lime</a>, <a href="https://publications.waset.org/abstracts/search?q=mortar" title=" mortar"> mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20resins" title=" natural resins"> natural resins</a>, <a href="https://publications.waset.org/abstracts/search?q=Manilkara%20zapota%20mixtures" title=" Manilkara zapota mixtures"> Manilkara zapota mixtures</a>, <a href="https://publications.waset.org/abstracts/search?q=Brosium%20alicastrum" title=" Brosium alicastrum"> Brosium alicastrum</a> </p> <a href="https://publications.waset.org/abstracts/29341/study-of-chemical-and-physical-mechanical-properties-lime-mortar-with-addition-of-natural-resins" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29341.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">371</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">41</span> Supply Chain Optimization for Silica Sand in a Glass Manufacturing Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Erasmo%20Verdin%20Rodriguez">Ramon Erasmo Verdin Rodriguez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many has been the ways that historically the managers and gurus has been trying to get closer to the perfect supply chain, but since this topic is so vast and very complex the bigger the companies are, the duty has not been certainly easy.

After a very quick passage thru the supply chain, this document is going to focus on the way that raw materials flow thru the system, so after that, an analysis and research can take place to improve the logistics. Thru Operations Research techniques, it will be analyzed the current scheme of distribution and inventories of raw materials at a glass company’s plants, so after a mathematical conceptualization process, the supply chain could be optimized with the purpose of reducing the uncertainty of supply and obtaining an economic benefit at the very end of this research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inventory%20management" title="inventory management">inventory management</a>, <a href="https://publications.waset.org/abstracts/search?q=operations%20research" title=" operations research"> operations research</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=supply%20chain" title=" supply chain"> supply chain</a> </p> <a href="https://publications.waset.org/abstracts/43207/supply-chain-optimization-for-silica-sand-in-a-glass-manufacturing-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43207.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">326</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">40</span> Using Multi-Arm Bandits to Optimize Game Play Metrics and Effective Game Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kenny%20Raharjo">Kenny Raharjo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Lawrence"> Ramon Lawrence</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Game designers have the challenging task of building games that engage players to spend their time and money on the game. There are an infinite number of game variations and design choices, and it is hard to systematically determine game design choices that will have positive experiences for players. In this work, we demonstrate how multi-arm bandits can be used to automatically explore game design variations to achieve improved player metrics. The advantage of multi-arm bandits is that they allow for continuous experimentation and variation, intrinsically converge to the best solution, and require no special infrastructure to use beyond allowing minor game variations to be deployed to users for evaluation. A user study confirms that applying multi-arm bandits was successful in determining the preferred game variation with highest play time metrics and can be a useful technique in a game designer's toolkit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=game%20design" title="game design">game design</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-arm%20bandit" title=" multi-arm bandit"> multi-arm bandit</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20exploration%20and%20data%20mining" title=" design exploration and data mining"> design exploration and data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=player%20metric%20optimization%20and%20analytics" title=" player metric optimization and analytics"> player metric optimization and analytics</a> </p> <a href="https://publications.waset.org/abstracts/56494/using-multi-arm-bandits-to-optimize-game-play-metrics-and-effective-game-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56494.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">510</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">39</span> Outstanding Lubricant Using Fluorographene as an Extreme Pressure Additive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Hernandez-Martinez">Adriana Hernandez-Martinez</a>, <a href="https://publications.waset.org/abstracts/search?q=Edgar%20D.%20Ramon-Raygoza"> Edgar D.

Likewise, fluorographene has also been gaining renown due to its excellent chemical and physical properties which have been mostly applied in the electronics industry. Nevertheless, its tribological properties haven’t been analyzed thoroughly. In this paper, fluorographene was examined as an extreme pressure additive and the nano lubricant made with a cutting fluid and fluorographene in the range of 0.01-0.5% wt, which proved to withstand 53.78% more pounds than the conventional product and 7.12% more than the nano lubricant with graphene in a range between 0.01-0.5% wt. Said extreme pressure test was carried out with a Pin and Vee Block Tribometer following an ASTM D3233A test. The fluorographene used has a low C/F ratio, which reflects a greater presence of atomic fluorine and its low oxygen percentage, supports the substitution of oxygen-containing groups by fluorine. XPS Spectra shows high atomic fluorine content of 56.12%, and SEM analysis details the formation of long and clear crystalline structures, in the fluorographene used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extreme%20pressure%20additive" title="extreme pressure additive">extreme pressure additive</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorographene" title=" fluorographene"> fluorographene</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofluids" title=" nanofluids"> nanofluids</a>, <a href="https://publications.waset.org/abstracts/search?q=nanolubricant" title=" nanolubricant"> nanolubricant</a> </p> <a href="https://publications.waset.org/abstracts/105687/outstanding-lubricant-using-fluorographene-as-an-extreme-pressure-additive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105687.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">124</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">38</span> Surface Integrity Improvement for Selective Laser Melting (SLM) Additive Manufacturing of C300 Parts Using Ball Burnishing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adrian%20Travieso%20Disotuar">Adrian Travieso Disotuar</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20Antonio%20Travieso%20Rodriguez"> J.

Besides, micro tensile tests were carried out in situ on Scanning Electron Microscopy to elucidate the post-treatment effects on damaging mechanisms. Experiments show that vibration-assisted ball burnishing significantly enhances mechanical properties compared to the non-vibration-assisted method.

Term frequency, along with metacognition and implicit corrective feedback, has often been identified as powerful variables in the learning of vocabulary in a foreign language. This study analyses the learning of L2 mobile operating system terminology by a group of students and uses the data collected by the video game The Conference Interpreter to identify the predictive strength of term frequency (times a term is shown), positive metacognition (times a right answer is provided), and negative metacognition (times a term is shown as wrong) regarding L2 vocabulary learning and perceived learning outcomes. The regression analysis shows that the factor ‘positive metacognition’ is a positive predictor of both dependent variables, whereas the other factors seem to have no statistical effect on any of them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20game-based%20learning" title="digital game-based learning">digital game-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=feedback" title=" feedback"> feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=metacognition" title=" metacognition"> metacognition</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=video%20games" title=" video games"> video games</a> </p> <a href="https://publications.waset.org/abstracts/99358/analysing-the-variables-that-affect-digital-game-based-l2-vocabulary-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99358.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">156</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">34</span> The Emotional Education in the Development of Intercultural Competences</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Montserrrat%20Dopico%20Gonzalez">Montserrrat Dopico Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Lopez%20Facal"> Ramon Lopez Facal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of a critical, open and plural citizenship constitutes one of the main challenges of the school institution in the present multicultural societies. Didactics in Social Sciences has conducted important contributions to the development of active methodologies to promote the development of the intercultural competencies of the student body. Research in intercultural education has demonstrated the efficiency of the cooperative learning techniques to improve the intercultural relations in the classroom. Our study proposes to check the effect that, concerning the development of intercultural competencies of the student body, the emotional education can have in the context of the use of active methodologies such as the learning by projects and the cooperative learning. To that purpose, a programme of intervention based on activities focussed on controversial issues related to cultural diversity has been implemented in several secondary schools. Through a methodology which combines intercultural competence scales with interviews and also with the analysis of the school body’s productions, the persistence of stereotypes against immigration and the efficacy of the introduction of emotional education elements in the development of intercultural competencies have both been observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20methodologies" title="active methodologies">active methodologies</a>, <a href="https://publications.waset.org/abstracts/search?q=didactics%20in%20social%20sciences" title=" didactics in social sciences"> didactics in social sciences</a>, <a href="https://publications.waset.org/abstracts/search?q=intercultural%20competences" title=" intercultural competences"> intercultural competences</a>, <a href="https://publications.waset.org/abstracts/search?q=intercultural%20education" title=" intercultural education"> intercultural education</a> </p> <a href="https://publications.waset.org/abstracts/98488/the-emotional-education-in-the-development-of-intercultural-competences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98488.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">154</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">33</span> Strategic Management Model for High Performance Sports Centers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jose%20Ramon%20Sanabria%20Navarro">Jose Ramon Sanabria Navarro</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahilina%20Silveira%20Perez"> Yahilina Silveira Perez</a>, <a href="https://publications.waset.org/abstracts/search?q=Valentin%20Molina%20Moreno"> Valentin Molina Moreno</a>, <a href="https://publications.waset.org/abstracts/search?q=Digna%20Dionisia%20Perez%20Bravo"> Digna Dionisia Perez Bravo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The general objective of this research is to conceive a model of strategic direction for Latin American high-performance sports centers for the improvement of their results.

This paper shows the results obtained during the hardware and software development of a Brain Computer Interface (BCI) capable of recognizing the human emotions through the association of the brain electrical activity patterns. The hardware involves the sensing stage and analogical-digital conversion. The interface software involves algorithms for pre-processing of the signal in time and frequency analysis and the classification of patterns associated with the electrical brain activity. The methods used for the analysis and classification of the signal have been tested separately, by using a database that is accessible to the public, besides to a comparison among classifiers in order to know the best performing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=affective%20computing" title="affective computing">affective computing</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=brain" title=" brain"> brain</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20interaction" title=" intelligent interaction"> intelligent interaction</a> </p> <a href="https://publications.waset.org/abstracts/27725/brain-computer-interface-implementation-for-affective-computing-sensing-classifiers-comparison" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27725.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">388</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">31</span> Providing Emotional Support to Children under Long-Term Health Treatments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ram%C3%B3n%20Cruzat">Ramón Cruzat</a>, <a href="https://publications.waset.org/abstracts/search?q=Sergio%20F.%20Ochoa"> Sergio F.

Such a situation also affects the evolution and effectiveness of their treatments. In many cases, the solution to this problem involves extra challenges, since many patients need to rest quietly (or remain in bed) to their being contagious. Considering the weak health condition in which usually are these kinds, keeping them motivated and quiet represents an important challenge for nurses and caregivers. This article presents a mobile ubiquitous game called MagicRace, which allows hospitalized kinds to interact socially with one another without putting to risk their sensitive health conditions. The game does not require a communication infrastructure at the hospital, but instead, it uses a mobile ad hoc network composed of the handheld devices used by the kids to play. The usability and performance of this application was tested in two different sessions. The preliminary results show that users experienced positive feelings from this experience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ubiquitous%20game" title="ubiquitous game">ubiquitous game</a>, <a href="https://publications.waset.org/abstracts/search?q=children%27s%20emotional%20support" title=" children's emotional support"> children's emotional support</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20isolation" title=" social isolation"> social isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20collaborative%20interactions" title=" mobile collaborative interactions"> mobile collaborative interactions</a> </p> <a href="https://publications.waset.org/abstracts/2537/providing-emotional-support-to-children-under-long-term-health-treatments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2537.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">430</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> Naturally Occurring Chemicals in Biopesticides' Resistance Control through Molecular Topology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riccardo%20Zanni">Riccardo Zanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Galvez-Llompart"> Maria Galvez-Llompart</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Garcia-Domenech"> Ramon Garcia-Domenech</a>, <a href="https://publications.waset.org/abstracts/search?q=Jorge%20Galvez"> Jorge Galvez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biopesticides, such as naturally occurring chemicals, pheromones, fungi, bacteria and insect predators are often a winning choice in crop protection because of their environmental friendly profile. They are considered to have lower toxicity than traditional pesticides. After almost a century of pesticides use, resistances to traditional insecticides are wide spread, while those to bioinsecticides have raised less attention, and resistance management is frequently neglected. This seems to be a crucial mistake since resistances have already occurred for many marketed biopesticides. With an eye to the future, we present here a selection of new natural occurring chemicals as potential bioinsecticides. The molecules were selected using a consolidated mathematical paradigm called molecular topology. Several QSAR equations were depicted and subsequently applied for the virtual screening of hundred thousands molecules of natural origin, which resulted in the selection of new potential bioinsecticides. The most innovative aspect of this work does not only reside in the importance of the identification of new molecules overcoming biopesticides’ resistances, but on the possibility to promote shared knowledge in the field of green chemistry through this unique in silico discipline named molecular topology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title="green chemistry">green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=QSAR" title=" QSAR"> QSAR</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20topology" title=" molecular topology"> molecular topology</a>, <a href="https://publications.waset.org/abstracts/search?q=biopesticide" title=" biopesticide"> biopesticide</a> </p> <a href="https://publications.waset.org/abstracts/60275/naturally-occurring-chemicals-in-biopesticides-resistance-control-through-molecular-topology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60275.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">314</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> A Biometric Template Security Approach to Fingerprints Based on Polynomial Transformations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Santana">Ramon Santana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of biometric identifiers in the field of information security, access control to resources, authentication in ATMs and banking among others, are of great concern because of the safety of biometric data. In the general architecture of a biometric system have been detected eight vulnerabilities, six of them allow obtaining minutiae template in plain text. The main consequence of obtaining minutia templates is the loss of biometric identifier for life. To mitigate these vulnerabilities several models to protect minutiae templates have been proposed. Several vulnerabilities in the cryptographic security of these models allow to obtain biometric data in plain text. In order to increase the cryptographic security and ease of reversibility, a minutiae templates protection model is proposed. The model aims to make the cryptographic protection and facilitate the reversibility of data using two levels of security. The first level of security is the data transformation level. In this level generates invariant data to rotation and translation, further transformation is irreversible. The second level of security is the evaluation level, where the encryption key is generated and data is evaluated using a defined evaluation function. The model is aimed at mitigating known vulnerabilities of the proposed models, basing its security on the impossibility of the polynomial reconstruction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fingerprint" title="fingerprint">fingerprint</a>, <a href="https://publications.waset.org/abstracts/search?q=template%20protection" title=" template protection"> template protection</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-cryptography" title=" bio-cryptography"> bio-cryptography</a>, <a href="https://publications.waset.org/abstracts/search?q=minutiae%20protection" title=" minutiae protection"> minutiae protection</a> </p> <a href="https://publications.waset.org/abstracts/95139/a-biometric-template-security-approach-to-fingerprints-based-on-polynomial-transformations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95139.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">170</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">28</span> Budgeting Procedures and Fiscal Stance of OECD Countries in the Wake of Global Economic Crisis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yulia%20Kasperskaya">Yulia Kasperskaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Xifr%C3%A9"> Ramon Xifré</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Budgetary procedures are considered to be important for countries’ fiscal performance. The objective of this paper is to analyze this relationship for the OECD countries in the wake of global economic crisis taking into consideration countries’ fiscal conditions and institutional arrangements. We test whether groups of countries that are fiscally different after the crisis differ in their use of budgetary procedures including performance budgeting, transparency mechanisms and medium-term expenditure framework. For this purpose, we classify OECD countries in two groups according to the variations, in debt to GDP ratio between 2008 and 2014. We then analyze the intensity of use of budget procedures taking into account countries’ economic conditions during the crisis. Our first finding is that there is no monotonic relationship between the intensity of use of these three budgetary procedures and enhanced fiscal performance. Countries showing similar fiscal performance scored differently in terms of on budgetary procedures. We, therefore, review the budgetary frameworks and trajectories of several countries that are fiscally sound. From this qualitative analysis, we derive a set of factors that may enhance the efficiency of budgetary procedures. This suggests that a given budgetary procedure may have different effects in different countries depending on their economic and administrative settings. Our results are thus in line with those studies that reject one-size-fits-all approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=budget%20procedures" title="budget procedures">budget procedures</a>, <a href="https://publications.waset.org/abstracts/search?q=fiscal%20performance" title=" fiscal performance"> fiscal performance</a>, <a href="https://publications.waset.org/abstracts/search?q=OECD" title=" OECD"> OECD</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20budgeting" title=" performance budgeting"> performance budgeting</a> </p> <a href="https://publications.waset.org/abstracts/53504/budgeting-procedures-and-fiscal-stance-of-oecd-countries-in-the-wake-of-global-economic-crisis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53504.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">239</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> A Lean Manufacturing Profile of Practices in the Metallurgical Industry: A Methodology for Multivariate Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Jonathan%20D.%20Morales">M.

Through the analysis of qualitative and quantitative variables it was possible to establish how these manufacturers develop production practices that ensure their competitiveness and productivity in the market. In this study, a random sample of metallurgic and wrought iron companies was applied, following which a quantitative focus and analysis was used to formulate a qualitative methodology for measuring the level of lean manufacturing procedures in the industry. A qualitative evaluation was also carried out through a multivariate analysis using the Numerical Taxonomy System (NTSYS) program which should allow for the determination of Lean Manufacturing profiles. Through the results it was possible to observe how the companies in the sector are doing with respect to Lean Manufacturing Practices, as well as identify the level of management that these companies practice with respect to this topic. In addition, it was possible to ascertain that there is no one dominant profile in the sector when it comes to Lean Manufacturing. It was established that the companies in the metallurgic and wrought iron industry show low levels of Lean Manufacturing implementation. Each one carries out diverse actions that are insufficient to consolidate a sectoral strategy for developing a competitive advantage which enables them to tie together a production strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=production%20line%20management" title="production line management">production line management</a>, <a href="https://publications.waset.org/abstracts/search?q=metallurgic%20industry" title=" metallurgic industry"> metallurgic industry</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a> </p> <a href="https://publications.waset.org/abstracts/14484/a-lean-manufacturing-profile-of-practices-in-the-metallurgical-industry-a-methodology-for-multivariate-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14484.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">459</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> Educational Experiences in Engineering in the COVID Era and Their Comparative Analysis, Spain, March to June 2020</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borja%20Bordel">Borja Bordel</a>, <a href="https://publications.waset.org/abstracts/search?q=Ram%C3%B3n%20Alcarria"> Ramón Alcarria</a>, <a href="https://publications.waset.org/abstracts/search?q=Marina%20P%C3%A9rez"> Marina Pérez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In March 2020, in Spain, a sanitary and unexpected crisis caused by COVID-19 was declared. All of a sudden, all degrees, classes and evaluation tests and projects had to be transformed into online activities. However, the chaotic situation generated by a complex operation like that, executed without any well-established procedure, led to very different experiences and, finally, results. In this paper, we are describing three experiences in two different Universities in Madrid. On the one hand, the Technical University of Madrid, a public university with little experience in online education. On the other hand, Alfonso X el Sabio University, a private university with more than five years of experience in online teaching. All analyzed subjects were related to computer engineering. Professors and students answered a survey and personal interviews were also carried out. Besides, the professors’ workload and the students’ academic results were also compared. From the comparative analysis of all these experiences, we are extracting the most successful strategies, methodologies, and activities. The recommendations in this paper will be useful for courses during the next months when the sanitary situation is still affecting an educational organization. While, at the same time, they will be considered as input for the upcoming digitalization process of higher education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20experience" title="educational experience">educational experience</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20education" title=" online education"> online education</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education%20digitalization" title=" higher education digitalization"> higher education digitalization</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID" title=" COVID"> COVID</a>, <a href="https://publications.waset.org/abstracts/search?q=Spain" title=" Spain"> Spain</a> </p> <a href="https://publications.waset.org/abstracts/140867/educational-experiences-in-engineering-in-the-covid-era-and-their-comparative-analysis-spain-march-to-june-2020" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140867.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">140</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">25</span> A Simulation-Optimization Approach to Control Production, Subcontracting and Maintenance Decisions for a Deteriorating Production System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H%C3%A9ctor%20Rivera-G%C3%B3mez">Héctor Rivera-Gómez</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Selene%20Hern%C3%A1ndez-Gress"> Eva Selene Hernández-Gress</a>, <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Monta%C3%B1o-Arango"> Oscar Montaño-Arango</a>, <a href="https://publications.waset.org/abstracts/search?q=Jose%20Ramon%20Corona-Armenta"> Jose Ramon Corona-Armenta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research studies the joint production, maintenance and subcontracting control policy for an unreliable deteriorating manufacturing system. Production activities are controlled by a derivation of the Hedging Point Policy, and given that the system is subject to deterioration, it reduces progressively its capacity to satisfy product demand. Multiple deterioration effects are considered, reflected mainly in the quality of the parts produced and the reliability of the machine. Subcontracting is available as support to satisfy product demand; also overhaul maintenance can be conducted to reduce the effects of deterioration. The main objective of the research is to determine simultaneously the production, maintenance and subcontracting rate which minimize the total incurred cost. A stochastic dynamic programming model is developed and solved through a simulation-based approach composed of statistical analysis and optimization with the response surface methodology. The obtained results highlight the strong interactions between production, deterioration and quality which justify the development of an integrated model. A numerical example and a sensitivity analysis are presented to validate our results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=subcontracting" title="subcontracting">subcontracting</a>, <a href="https://publications.waset.org/abstracts/search?q=optimal%20control" title=" optimal control"> optimal control</a>, <a href="https://publications.waset.org/abstracts/search?q=deterioration" title=" deterioration"> deterioration</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20planning" title=" production planning"> production planning</a> </p> <a href="https://publications.waset.org/abstracts/31365/a-simulation-optimization-approach-to-control-production-subcontracting-and-maintenance-decisions-for-a-deteriorating-production-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31365.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">579</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">24</span> Hunting Ban, Unfortunate Decisions for the Bear Population in Romania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandru%20Gridan">Alexandru Gridan</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgeta%20Ionescu"> Georgeta Ionescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ovidiu%20%20Ionescu"> Ovidiu Ionescu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramon%20Jurj"> Ramon Jurj</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Sirbu"> George Sirbu</a>, <a href="https://publications.waset.org/abstracts/search?q=Mihai%20Fedorca"> Mihai Fedorca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Brown Bear population size in Romania is approximately 7300-7600 individuals, which is projected to be 3000 individuals over the ecological carrying capacity. The Habitats Directive imposed certain protection rules on European Union (EU) Member States with Brown Bear populations. These however allow countries like Sweden, Croatia, Slovakia, Estonia to hunting as management tool, harvesting up to 10% of the surplus bear population annually. From the point Romania joined the EU to 2016, active conservation management has contributed to maintaining the highest and most genetically diverse Brown Bear population in Europe. Importantly, there has been good coexistence between people and bears and low levels of human-bear conflict. After social pressure and campaigning by some non-governmental organisations citing issues over monitoring, the environment minister decided in September 2016 to stop the use of hunting as a management tool for bears. Against this background, this paper provides a set of recommendations to resolve the current conflict in Romania. These include the need for collaborative decision-making to reduce conflicts between stakeholders and mechanisms to reduce current human-bear conflicts, which have increased by 50 percent in the past year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bear" title="bear">bear</a>, <a href="https://publications.waset.org/abstracts/search?q=bear%20population" title=" bear population"> bear population</a>, <a href="https://publications.waset.org/abstracts/search?q=bear%20management" title=" bear management"> bear management</a>, <a href="https://publications.waset.org/abstracts/search?q=wildlife%20conflict" title=" wildlife conflict"> wildlife conflict</a> </p> <a href="https://publications.waset.org/abstracts/80782/hunting-ban-unfortunate-decisions-for-the-bear-population-in-romania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80782.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">182</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">23</span> CEO Narcissism and Gender Diversity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emma%20Garcia-Meca">Emma Garcia-Meca</a>, <a href="https://publications.waset.org/abstracts/search?q=Jennifer%20Martinez-Ferrero"> Jennifer Martinez-Ferrero</a>, <a href="https://publications.waset.org/abstracts/search?q=Camino%20Ramon%20Llorens"> Camino Ramon Llorens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides insights into how narcissistic Chief Executive Officers (CEOs) influence the presence of women in top management teams (TMT). We also study whether a CEO's power and gender and the gender diversity of the firm's board moderate the relationship between CEO narcissism and TMT gender diversity. Our results reveal that narcissistic CEOs are less likely to support women in TMTs, confirming that CEO personality traits influence team structure. Further results suggest that this aversion increases as the CEO's power grows when female representation on boards decreases and when the CEO is a woman. This paper integrates theories that use the social psychology and upper echelon theories, offering a greater understanding of how CEO personality traits influence the structure of firms. We also contribute to the knowledge about how different governance characteristics can moderate the influence of narcissistic CEOs on women in TMTs, highlighting the relevance of governance traits that increase the effect of narcissism. The results demonstrate different female behavior toward promoting TMT gender equality depending on the specific position of women in the firm's hierarchy and their psychological attributes. We find that women directors support social identity values, and narcissistic female CEOs act like queen bees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20diversity" title="gender diversity">gender diversity</a>, <a href="https://publications.waset.org/abstracts/search?q=board" title=" board"> board</a>, <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title=" corporate governance"> corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20CEO" title=" female CEO"> female CEO</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a> </p> <a href="https://publications.waset.org/abstracts/153753/ceo-narcissism-and-gender-diversity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153753.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">118</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">22</span> Experimental Study for the Development of a Wireless Communication System in a Solar Central Tower Facility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Victor%20H.%20Benitez">Victor H.

Solar power tower technology is a good example of this type of system, which consists of several mobile mirrors, called heliostats, which reflect the sun's radiation to the same point, located on top of a tower at the center of heliostat field, for collection or transformation into another type of energy. The so-called Hermosillo’s Solar Platform (Plataforma Solar de Hermosillo, PSH, in Spanish) is a facility constituted with several heliostats, its aim and scope is for research purposes. In this paper, the implementation of a wireless communication system based on intelligent nodes is proposed in order to allow the communication and control of the heliostats in PSH. Intelligent nodes transmit information from one point to another, and can perform other actions that allow them to adapt to the conditions and limitations of a field of heliostats, thus achieving effective communication system. After deployment of the nodes in the heliostats, tests were conducted to measure the effectiveness of the communication, and determine the feasibility of using the proposed technologies. The test results were always positive, exceeding expectations held for its operation in the field of heliostats. Therefore, it was possible to validate the efficiency of the wireless communication system to be implemented in PSH, allowing communication and control of the heliostats. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heliostat" title="heliostat">heliostat</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligent%20node" title=" intelligent node"> intelligent node</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20communication" title=" wireless communication"> wireless communication</a> </p> <a href="https://publications.waset.org/abstracts/37803/experimental-study-for-the-development-of-a-wireless-communication-system-in-a-solar-central-tower-facility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37803.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">408</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> Machine Learning for Classifying Risks of Death and Length of Stay of Patients in Intensive Unit Care Beds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Itamir%20de%20Morais%20Barroca%20Filho">Itamir de Morais Barroca Filho</a>, <a href="https://publications.waset.org/abstracts/search?q=Cephas%20A.%20S.%20Barreto"> Cephas A.

These ICTs are also known as e-health and comprise technologies such as electronic record systems, telemedicine systems, and personalized devices for diagnosis. The focus of e-health is to improve the quality of health information, strengthen national health systems, and ensure accessible, high-quality health care for all. All the data gathered by these technologies make it possible to help clinical staff with automated decisions using machine learning. In this context, we collected patient data, such as heart rate, oxygen saturation (SpO2), blood pressure, respiration, and others. With this data, we were able to develop machine learning models for patients’ risk of death and estimate the length of stay in ICU beds. Thus, this paper presents the methodology for applying machine learning techniques to develop these models. As a result, although we implemented these models on an IoT healthcare platform, helping clinical staff in healthcare in an ICU, it is essential to create a robust clinical validation process and monitoring of the proposed models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ICT" title="ICT">ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=e-health" title=" e-health"> e-health</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=ICU" title=" ICU"> ICU</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare" title=" healthcare"> healthcare</a> </p> <a href="https://publications.waset.org/abstracts/163535/machine-learning-for-classifying-risks-of-death-and-length-of-stay-of-patients-in-intensive-unit-care-beds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163535.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">20</span> Characterization of Heterotrimeric G Protein α Subunit in Tomato</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thi%20Thao%20Ninh">Thi Thao Ninh</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuri%20Trusov"> Yuri Trusov</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Ram%C3%B3n%20Botella"> José Ramón Botella</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterotrimeric G proteins, comprised of three subunits, α, β and γ, are involved in signal transduction pathways that mediate a vast number of processes across the eukaryotic kingdom. 23 Gα subunits are present in humans whereas most plant genomes encode for only one canonical Gα. The disparity observed between Arabidopsis, rice, and maize Gα-deficient mutant phenotypes suggest that Gα functions have diversified between eudicots and monocots during evolution. Alternatively, since the only Gα mutations available in dicots have been produced in Arabidopsis, the possibility exists that this species might be an exception to the rule. In order to test this hypothesis, we studied the G protein α subunit (TGA1) in tomato. Four tga1 knockout lines were generated in tomato cultivar Moneymaker using CRISPR/Cas9. The tga1 mutants exhibit a number of auxin-related phenotypes including changes in leaf shape, reduced plant height, fruit size and number of seeds per fruit. In addition, tga1 mutants have increased sensitivity to abscisic acid during seed germination, reduced sensitivity to exogenous auxin during adventitious root formation from cotyledons and excised hypocotyl explants. Our results suggest that Gα mutant phenotypes in tomato are very similar to those observed in monocots, i.e. rice and maize, and cast doubts about the validity of using Arabidopsis as a model system for plant G protein studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxin-related%20phenotypes" title="auxin-related phenotypes">auxin-related phenotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=CRISPR%2FCas9" title=" CRISPR/Cas9"> CRISPR/Cas9</a>, <a href="https://publications.waset.org/abstracts/search?q=G%20protein%20%CE%B1%20subunit" title=" G protein α subunit"> G protein α subunit</a>, <a href="https://publications.waset.org/abstracts/search?q=heterotrimeric%20G%20proteins" title=" heterotrimeric G proteins"> heterotrimeric G proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a> </p> <a href="https://publications.waset.org/abstracts/110538/characterization-of-heterotrimeric-g-protein-a-subunit-in-tomato" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110538.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">136</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> Utilization of Manila Clam Shells (Venerupis Philippinarum) and Raffia Palm Fiber (Raphia Farinifera) as an Additive in Producing Concrete Roof Tiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sofina%20Faith%20C.%20Navarro">Sofina Faith C.

The study focuses on the production of sustainable roof tiles that address the waste disposal challenges associated with Manila clam shells and mitigate the environmental impact of conventional roof tile materials. Various concentrations of roof tiles are developed, incorporating different proportions of powdered clam shell that contains calcium carbonate and shredded raffia palm fiber. Subsequently, the roof tiles are cast using standard methods and transported to the University of the Philippines Institute of Civil Engineering (UP-ICE) for flexural strength testing. In conclusion, the research aimed to assess the flexural durability of concrete roof tiles with varying concentrations of Raffia Palm Fiber and Manila Clam Shells additives. The findings indicate notable differences in maximum load capacities among the specimens, with C3.1 emerging as the concentration with the highest load-bearing capacity at 313.59729 N. This concentration, with a flexural strength of 2.15214, is identified as the most durable option, with a slightly heavier weight of 1.10 kg. On the other hand, C2.2, with a flexural strength of 0.366 and a weight of 0.80 kg, is highlighted for its impressive durability performance while maintaining a lighter composition. Therefore, for the production of concrete roof tile, C3.1 is recommended for optimal durability, while C2.2 is suggested as a preferable option considering both durability and lightweight characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=raffia%20palm%20fiber" title="raffia palm fiber">raffia palm fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweightness" title=" lightweightness"> lightweightness</a>, <a href="https://publications.waset.org/abstracts/search?q=Manila%20Clam%20Shells" title=" Manila Clam Shells"> Manila Clam Shells</a> </p> <a href="https://publications.waset.org/abstracts/183114/utilization-of-manila-clam-shells-venerupis-philippinarum-and-raffia-palm-fiber-raphia-farinifera-as-an-additive-in-producing-concrete-roof-tiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183114.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">61</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> Utilization of Manila Clam Shells (Venerupis Philippinarum) and Raffia Palm Fiber (Raphia Farinifera) as an Additive in Producing Concrete Roof Tiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alfonzo%20Ramon%20Burguete">Alfonzo Ramon Burguete</a>, <a href="https://publications.waset.org/abstracts/search?q=Rica%20Gatus"> Rica Gatus</a>, <a href="https://publications.waset.org/abstracts/search?q=Sofina%20Faith%20Navarro"> Sofina Faith Navarro</a>, <a href="https://publications.waset.org/abstracts/search?q=Luke%20Subala"> Luke Subala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Roof tiles, as integral components of buildings, play a crucial role in protecting structures from many things.
