</p> <p class="card-text"><strong>Abstract:</strong></p> This article describes a set of innovating student recruitment strategies in a 1st cycle course of Civil Engineering, in particular the Civil Engineering Degree from the School of Engineering - Polytechnic of Porto (ISEP-PP). The strategies described were two-fold, targeting, for one, the increment on the number of admissions for the degree’s first year and two, promoting the re-entry of students who, for whatever reason, interrupted their studies. For the first objective, teacher-student binomials were set, whilst for the second, personalized contacts and assistance were provided. The main initiatives were promoted by the team of degree directors and were upheld with the participation and in consonance with the School’s external relations office. These initiatives were put forward as an attempt to minimize the impact of a national and international crisis on the AEC industry when the sustainability of the course was at risk. The implementation of these strategies was assessed on basis of a statistical analysis of the data collected from official sources and by surveys promoted. The results showed that the re-entry boost of former students, attending classes scattered on the three curricular years, secured registrations on some Curricular Units (UC’s) which more than doubled their numbers. Accompanied by a still incipient but regained interest on Civil Engineering it was possible in the short span of three years to reset the number of new students from less than 10 to the currently maximum allowed of 75, and so invert the tendency of an abrupt decline on the total number of students enrolled on the degree. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=civil%20engineering" title="civil engineering">civil engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20indicators" title=" performance indicators"> performance indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=strategies" title=" strategies"> strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=student%20recruitment" title=" student recruitment"> student recruitment</a> </p> <a href="https://publications.waset.org/abstracts/80716/strategies-for-student-recruitment-in-civil-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80716.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">213</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">120</span> Application of Computational Fluid Dynamics in the Analysis of Water Flow in Rice Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcio%20Mesquita">Marcio Mesquita</a>, <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Henrique%20Morato%20de%20Moraes"> Diogo Henrique Morato de Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Henrique%20Fonseca%20Elias%20de%20Oliveira"> Henrique Fonseca Elias de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Rilner%20Alves%20Flores"> Rilner Alves Flores</a>, <a href="https://publications.waset.org/abstracts/search?q=Mateus%20Rodrigues%20Ferreira"> Mateus Rodrigues Ferreira</a>, <a href="https://publications.waset.org/abstracts/search?q=Dalva%20Graciano%20Ribeiro"> Dalva Graciano Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to analyze the movement of water in irrigated and non-irrigated rice (Oryza sativa L.) leaves, from the xylem to the stomata, through numerical simulations. Through three-dimensional modeling, it was possible to determine how the spacing of parenchyma cells and the permeability of these cells influence the apoplastic flow and the opening of the stomata. The thickness of the cuticle and the number of vascular bundles are greater in plants subjected to water stress, indicating an adaptive response of plants to environments with water deficit. In addition, numerical simulations revealed that the opening of the stomata, the permeability of the parenchyma cells and the cell spacing have significant impacts on the energy loss and the speed of water movement. It was observed that a more open stoma facilitates water flow, decreasing the resistance and energy required for transport, while higher levels of permeability reduce energy loss, indicating that a more permeable tissue allows for more efficient water transport. Furthermore, it was possible to note that stomatal aperture, parenchyma permeability and cell spacing are crucial factors in the efficient water management of plants, especially under water stress conditions. These insights are essential for the development of more effective agricultural management strategies and for the breeding of plant varieties that are more resistant to adverse growing conditions. Computed fluid dynamics has allowed us to overcome the limitations of conventional techniques by providing a means to visualize and understand the complex hydrodynamic processes within the vascular system of plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title="numerical modeling">numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20anatomy" title=" vascular anatomy"> vascular anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular%20hydrodynamics" title=" vascular hydrodynamics"> vascular hydrodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=xylem" title=" xylem"> xylem</a>, <a href="https://publications.waset.org/abstracts/search?q=Oryza%20sativa%20L." title=" Oryza sativa L."> Oryza sativa L.</a> </p> <a href="https://publications.waset.org/abstracts/192197/application-of-computational-fluid-dynamics-in-the-analysis-of-water-flow-in-rice-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192197.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">17</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">119</span> Particle Swarm Optimization and Quantum Particle Swarm Optimization to Multidimensional Function Approximation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Silva">Diogo Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Fadul%20Rodor"> Fadul Rodor</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Moraes"> Carlos Moraes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work compares the results of multidimensional function approximation using two algorithms: the classical Particle Swarm Optimization (PSO) and the Quantum Particle Swarm Optimization (QPSO).

NMS isn’t a serious game, and not all the science in the game is presented with scientific evidence. To find how players felt about the scientific content in the game and how they perceive the chemistry in it, a survey was sent to NMS’s players, from which were collected answers from 124 respondents from 23 countries. Chemophobia is still a phenomenon when chemistry or chemicals are a subject of discussion, but 68,9% of our respondents showed a positive attitude towards the presence of chemistry in NMS, with 57% stating that playing the video game motivated them to know more about science. 8% of the players stated that NMS often prompted conversations about the science in the video game between them and teachers, parents, or friends. These results give us ideas on how an entertainment game can potentially help scientists, educators, and science communicators reach a growing, evolving, vibrant, diverse, and demanding audience. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digital%20games" title="digital games">digital games</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20communication" title=" science communication"> science communication</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</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=No%20Man%E2%80%99s%20Sky" title=" No Man’s Sky"> No Man’s Sky</a> </p> <a href="https://publications.waset.org/abstracts/156533/the-chemistry-in-the-video-game-no-mans-sky" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156533.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">110</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">117</span> Rank of Semigroup: Generating Sets and Cases Revealing Limitations of the Concept of Independence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zsolt%20Lipcsey">Zsolt Lipcsey</a>, <a href="https://publications.waset.org/abstracts/search?q=Sampson%20Marshal%20Imeh"> Sampson Marshal Imeh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> We investigate a certain characterisation for rank of a semigroup by Howie and Ribeiro (1999), to ascertain the relevance of the concept of independence.

For that, the inOrdinatio method was adopted, which defines the form of selection and classification of articles. The search was carried out in databases, which resulted in a total of 619 documents that were cataloged and classified with the support of the Mendeley software. The theoretical scope intended here is to identify how performance in police organizations has been studied. After deepening the analysis and focusing on management, it was possible to classify the articles into three levels: individual, organizational, and institutional. However, to our best knowledge, no studies were found that addressed the performance relationship between the levels, which can be seen as a suggestion for further research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=police%20management" title="police management">police management</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-level" title=" multi-level"> multi-level</a> </p> <a href="https://publications.waset.org/abstracts/153739/performance-in-police-organizations-approaches-from-the-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153739.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">108</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">112</span> Automation of Kitchen Chemical in the Textile Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luiz%20da%20Silva%20Neto">José Luiz da Silva Neto</a>, <a href="https://publications.waset.org/abstracts/search?q=Renato%20Sipelli%20Silva"> Renato Sipelli Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%89rick%20Arag%C3%A3o%20Ribeiro"> Érick Aragão Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The automation of industrial processes plays a vital role in industries today, becoming an integral and important part of the industrial process and modern production.

Europe has been addressing these problems, namely through the Green Deal, with the use of batteries in mobility and energy fields. However, these require the use of critical raw materials, like lithium, which demand is estimated to grow 60 times in the next 30 years. Thus, it is fundamental to promote a circular economy with lithium recovery from secondary resources. These are nowadays key topics, which will be even more relevant in the future, so a new way to approach them is needed and must be encouraged. Therefore, one of our main goals is to analyse two methods of lithium retrieval from secondary sources, bioleaching, and electrodialysis, and assess them regarding their sustainability. The latest results show good efficiency of removal with both methods, even though there are some matrix interferences. Hence, further investment and research are needed in order to make this process sustainable and our society more circular. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium" title="lithium">lithium</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20mining" title=" sustainable mining"> sustainable mining</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20license%20to%20operate" title=" social license to operate"> social license to operate</a>, <a href="https://publications.waset.org/abstracts/search?q=bioleaching" title=" bioleaching"> bioleaching</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a> </p> <a href="https://publications.waset.org/abstracts/147171/assessing-lithium-recovery-from-secondary-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">108</span> Synchrony between Genetic Repressilators in Sister Cells in Different Temperatures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jerome%20G.%20Chandraseelan">Jerome G.

We found that both the mean and the variability of the degree of synchrony between the fluorescence signals from sister cells are affected by temperature. Also, while most pairs of sister cells were found to be highly synchronous in each condition, the number of asynchronous pairs increased with increasing temperature, which was found to be due to disruptions in the oscillations. Finally we provide evidence that these disruptions tend to affect multiple generations as opposed to individual cells. These findings provide insight in how to design more robust synthetic circuits and in how cell division can affect their dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=repressilator" title="repressilator">repressilator</a>, <a href="https://publications.waset.org/abstracts/search?q=robustness" title=" robustness"> robustness</a>, <a href="https://publications.waset.org/abstracts/search?q=synchrony" title=" synchrony"> synchrony</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20biology" title=" synthetic biology"> synthetic biology</a> </p> <a href="https://publications.waset.org/abstracts/24590/synchrony-between-genetic-repressilators-in-sister-cells-in-different-temperatures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24590.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">483</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">107</span> Educational Robotics with Easy Implementation and Low Cost</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maria%20R.%20A.%20R.%20Moreira">Maria R.

One of the main reasons for application of the developed educational kits is its low cost, allowing its applicability to a greater number of educational institutions. The technology will add to education dissemination of knowledge by means of experiments in such a way that the pedagogical robotics promotes understanding, practice, solution and criticism about classroom challenges.

Human landscape-shaping inadvertently alters other species’ habitats –most often decimating them, but sometimes improving them–, the outcomes of which always resonate back upon human inhabitation and land use. Despite the overall tendency of biotic homogenization resulting from modern deforestation processes, there are always winners, i.e., species that gain competitive advantages enabling them to thrive in the novel ecosystems. Here it is examined one such case of deforestation-boosted species, namely leafcutter ants, which wrought havoc in the rural landscapes of nineteenth-century Brazil by defoliating a wide range of crops. By combining Historical GIS analysis and qualitative interpretation, it is shown how agricultural deforestation might have changed the ant species' biogeographies, and how in turn these changes – construed as 'infestation' – stimulated social innovations and rearrangements such as technical ingenuity, legal-administrative practices, and even local electoral arenas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deforestation" title="deforestation">deforestation</a>, <a href="https://publications.waset.org/abstracts/search?q=leafcutter%20ants" title=" leafcutter ants"> leafcutter ants</a>, <a href="https://publications.waset.org/abstracts/search?q=nineteenth-century%20Brazil" title=" nineteenth-century Brazil"> nineteenth-century Brazil</a>, <a href="https://publications.waset.org/abstracts/search?q=socio-ecological%20change" title=" socio-ecological change"> socio-ecological change</a> </p> <a href="https://publications.waset.org/abstracts/108762/creatures-of-the-clearing-forests-people-and-ants-in-imperial-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108762.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">104</span> Economic Analysis of Domestic Combined Heat and Power System in the UK</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thamo%20Sutharssan">Thamo Sutharssan</a>, <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Montalvao"> Diogo Montalvao</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Chung%20Wang"> Wen-Chung Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Chen"> Yong Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Claudia%20Pisac"> Claudia Pisac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A combined heat and power (CHP) system is an efficient and clean way to generate power (electricity). Heat produced by the CHP system can be used for water and space heating. The CHP system which uses hydrogen as fuel produces zero carbon emission. Its’ efficiency can reach more than 80% whereas that of a traditional power station can only reach up to 50% because much of the thermal energy is wasted. The other advantages of CHP systems include that they can decentralize energy generation, improve energy security and sustainability, and significantly reduce the energy cost to the users. This paper presents the economic benefits of using a CHP system in the domestic environment. For this analysis, natural gas is considered as potential fuel as the hydrogen fuel cell based CHP systems are rarely used. UK government incentives for CHP systems are also considered as the added benefit. Results show that CHP requires a significant initial investment in return it can reduce the annual energy bill significantly. Results show that an investment may be paid back in 7 years. After the back period, CHP can run for about 3 years as most of the CHP manufacturers provide 10-year warranty. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=combined%20heat%20and%20power" title="combined heat and power">combined heat and power</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title=" clean energy"> clean energy</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20fuel%20cell" title=" hydrogen fuel cell"> hydrogen fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20analysis%20of%20CHP" title=" economic analysis of CHP"> economic analysis of CHP</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20emission" title=" zero emission"> zero emission</a> </p> <a href="https://publications.waset.org/abstracts/42782/economic-analysis-of-domestic-combined-heat-and-power-system-in-the-uk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42782.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">385</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">103</span> A Bilingual Didactic Sequence about Biological Control to Develop the Scientific Literacy on High School Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9%20Melo%20Franco%20Lorena%20De%20Barros">André Melo Franco Lorena De Barros</a>, <a href="https://publications.waset.org/abstracts/search?q=Elida%20Geralda%20Campos"> Elida Geralda Campos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The bilingual education has just started in Brazils public schools. This paper is a didactic sequence of biology bilingual lessons about biologic control in the Brazilian Savana. This sequence has been applied in the first year of a bilingual education program in the only public English and Portuguese bilingual high school in Brazil. The aim of this work is to develop and apply a didactic sequence capable of developing the scientific literacy through the bilingual education associated with Problem Based Learning. This didactic sequence was applied in a class of 30 students. It was divided in three lessons. In the first lesson the students were divided in groups and received a fiction Letter from a mayor explaining the problem and asking students for help. The organic soy plantation of the mayor’s is been attacked by caterpillars. The students read the text then raised hypothesis of how they could solve the problem. In the second lesson the students searched online to verify if theirs hypothesis were correct and to find answers for the question proposed. In the third lesson the groups got together and discussed about their results and wrote a final essay with the answers for the problem proposed. The tools used to acquire information about the didactic sequence were: researcher’s diary, survey, interview and essay developed by the students. Most of the initial hypothesis couldn’t answer the problem properly. By the second lesson most of the students could answer properly. During the third lesson all the groups figured out suitable answers. The forms of biological control, birds habits and transgenic were deeply studied by the students. This methodology was successful for developing the scientific literacy with most of the students and also concluded that the quality of learning is directly associated with the effort of each student during the process.

Thus, there is a need of models for assessing the quality of airport services. Because of this, the main objective of this work is to propose a model for the evaluation of quality attributes in airport services. To this end, we used the method composed by literature review and interview. Structured a working method composed by 5 steps, which resulted in a model to evaluate the quality of airport services, consisting of 8 dimensions and 45 attributes. Was used as base for model definition the process mapping of boarding and landing processes of passengers and luggage. As a contribution of this work is the integration of management process with structuring models to assess the quality of services in airport environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quality%20airport%20services" title="quality airport services">quality airport services</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20for%20identification%20of%20attributes%20quality" title=" model for identification of attributes quality"> model for identification of attributes quality</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20transport" title=" air transport"> air transport</a>, <a href="https://publications.waset.org/abstracts/search?q=passenger" title=" passenger"> passenger</a> </p> <a href="https://publications.waset.org/abstracts/24893/model-for-assessment-of-quality-airport-services" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24893.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">535</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">101</span> Spectroscopic Study of a Eu-Complex Containing Hybrid Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20A.%20R.%20Oliveira">Y.

A detailed analysis of the emission spectra revealed that the EuTTA phase still remains in the hybrid phase. Sparkle Model calculations of the EuTTA ground state geometry have been performed and satisfactorily compared to the X-ray structure. The observed weaker crystal field strength of the phase generated by the incorporation is promptly interpreted through the existing EXAFS results of the EuTTA-hyb structure. Satisfactory predictions of the CFP, of the 7F1 level splitting and of the Ωλ in all cases were obtained by using the charge factors and polarizabilities as degrees of freedom of non-parametric models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crystal%20field%20parameters" title="crystal field parameters">crystal field parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=europium%20complexes" title=" europium complexes"> europium complexes</a>, <a href="https://publications.waset.org/abstracts/search?q=Judd-Ofelt%20intensity%20parameters" title=" Judd-Ofelt intensity parameters"> Judd-Ofelt intensity parameters</a> </p> <a href="https://publications.waset.org/abstracts/13357/spectroscopic-study-of-a-eu-complex-containing-hybrid-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13357.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">100</span> Extension-Torsion-Inflation Coupling in Compressible Magnetoelastomeric Tubes with Helical Magnetic Anisotropy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Darius%20Diogo%20Barreto">Darius Diogo Barreto</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajeet%20Kumar"> Ajeet Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Sushma%20Santapuri"> Sushma Santapuri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We present an axisymmetric variational formulation for coupled extension-torsion-inflation deformation in magnetoelastomeric thin tubes when both azimuthal and axial magnetic fields are applied. The tube's material is assumed to have a preferred magnetization direction which imparts helical magnetic anisotropy to the tube. We have also derived the expressions of the first derivative of free energy per unit tube's undeformed length with respect to various imposed strain parameters. On applying the thin tube limit, the two nonlinear ordinary differential equations to obtain the in-plane radial displacement and radial component of the Lagrangian magnetic field get converted into a set of three simple algebraic equations. This allows us to obtain simple analytical expressions in terms of the applied magnetic field, magnetization direction, and magnetoelastic constants, which tell us how these parameters can be tuned to generate positive/negative Poisson's effect in such tubes. We consider both torsionally constrained and torsionally relaxed stretching of the tube. The study can be useful in designing magnetoelastic tubular actuators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20magnetoelasticity" title="nonlinear magnetoelasticity">nonlinear magnetoelasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=extension-torsion%20coupling" title=" extension-torsion coupling"> extension-torsion coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20Poisson%27s%20effect" title=" negative Poisson's effect"> negative Poisson's effect</a>, <a href="https://publications.waset.org/abstracts/search?q=helical%20anisotropy" title=" helical anisotropy"> helical anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20tube" title=" thin tube"> thin tube</a> </p> <a href="https://publications.waset.org/abstracts/115693/extension-torsion-inflation-coupling-in-compressible-magnetoelastomeric-tubes-with-helical-magnetic-anisotropy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115693.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">120</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">99</span> Models Development of Graphical Human Interface Using Fuzzy Logic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%89rick%20Arag%C3%A3o%20Ribeiro">Érick Aragão Ribeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Andr%C3%A9%20Pereira%20Th%C3%A9"> George André Pereira Thé</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Marques%20Soares"> José Marques Soares</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Graphical Human Interface, also known as supervision software, are increasingly present in industrial processes supported by Supervisory Control and Data Acquisition (SCADA) systems and so it is evident the need for qualified developers.

In the context of macroscopic poroelastoplasticity, the hydromechanical coupling between the skeleton deformation and the fluid pressure is addressed by means of two constitutive equations. The first state equation relates the stress to skeleton strain and pore pressure, while the second state equation relates the Lagrangian porosity change to skeleton volume strain and pore pressure. A specific algorithm for local plastic integration using a tangent operator is devised. A modified Cam-clay type yield surface with associated plastic flow rule is adopted to account for both contractive and dilative behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title="finite element method">finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=poromechanics" title=" poromechanics"> poromechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=poroplasticity" title=" poroplasticity"> poroplasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20analysis" title=" reservoir analysis"> reservoir analysis</a> </p> <a href="https://publications.waset.org/abstracts/65748/a-parallel-poromechanics-finite-element-method-fem-model-for-reservoir-analyses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65748.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">391</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">95</span> Symbolic Partial Differential Equations Analysis Using Mathematica</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davit%20Shahnazaryan">Davit Shahnazaryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Diogo%20Gomes"> Diogo Gomes</a>, <a href="https://publications.waset.org/abstracts/search?q=Mher%20%20Safaryan"> Mher Safaryan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many symbolic computations and manipulations required in the analysis of partial differential equations (PDE) or systems of PDEs are tedious and error-prone. These computations arise when determining conservation laws, entropies or integral identities, which are essential tools for the study of PDEs. Here, we discuss a new Mathematica package for the symbolic analysis of PDEs that automate multiple tasks, saving time and effort. Methodologies: During the research, we have used concepts of linear algebra and partial differential equations. We have been working on creating algorithms based on theoretical mathematics to find results mentioned below. Major Findings: Our package provides the following functionalities; finding symmetry group of different PDE systems, generation of polynomials invariant with respect to different symmetry groups; simplification of integral quantities by integration by parts and null Lagrangian cleaning, computing general forms of expressions by integration by parts; finding equivalent forms of an integral expression that are simpler or more symmetric form; determining necessary and sufficient conditions on the coefficients for the positivity of a given symbolic expression. Conclusion: Using this package, we can simplify integral identities, find conserved and dissipated quantities of time-dependent PDE or system of PDEs. Some examples in the theory of mean-field games and semiconductor equations are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20differential%20equations" title="partial differential equations">partial differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=symbolic%20computation" title=" symbolic computation"> symbolic computation</a>, <a href="https://publications.waset.org/abstracts/search?q=conserved%20and%20dissipated%20quantities" title=" conserved and dissipated quantities"> conserved and dissipated quantities</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematica" title=" mathematica"> mathematica</a> </p> <a href="https://publications.waset.org/abstracts/95037/symbolic-partial-differential-equations-analysis-using-mathematica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95037.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">163</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">94</span> Incorporation of Foundry Sand in Asphalt Pavement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20P.%20Nascimento">L.

Thus, with the techno-scientific growth and in the perspective of sustainability, it is observed that waste has the potential to replace significant percentages of materials considered “virgin”. An example is the replacement of crushed aggregates with foundry sand. In this work, a mix design study of two asphalt mixes, a base mix (AC 20) and a surface mix (AC14) was carried out to evaluate the maximum amount of foundry sand residue that could be used. Water sensitivity tests were performed to evaluate the mechanical behavior of these mixtures. For the superficial mixture with foundry sand (AC14FS), the maximum of sand used was 5%, with satisfactory results of sensitivity to water. In the base mixture with sand (AC20FS), the maximum of sand used was 12%, which had less satisfactory results. However, from an environmental point of view, the re-incorporation of this residue in the pavement is beneficial because it prevents it from being deposited in landfills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foundry%20sand" title="foundry sand">foundry sand</a>, <a href="https://publications.waset.org/abstracts/search?q=hot%20mix%20asphalt" title=" hot mix asphalt"> hot mix asphalt</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20waste" title=" industrial waste"> industrial waste</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20valorization" title=" waste valorization"> waste valorization</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/152830/incorporation-of-foundry-sand-in-asphalt-pavement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152830.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">111</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">93</span> Investigation of Polymer Composite for High Dose Dosimetry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Esther%20Lorrayne%20%20M.%20Pereira">Esther Lorrayne M.

FTIR spectrometry has that the absorbance intensities at 1715 cm⁻¹ and 1730 cm⁻¹ can be used for high dosimetry purposes for gamma doses ranging from 500 to 2750 kGy. In this range, it is possible to observe a linear relationship between Abs & Dose. Fading of signal was evaluated for one month and reproducibility in 2000 kGy dose. Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX) was used for evaluated the dispersion ZrO₂ and MWCNT in the matrix of the PVDF. <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=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20dose%20dosimetry" title=" high dose dosimetry"> high dose dosimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=PVDF%2FZrO%E2%82%82%2FMWCNT" title=" PVDF/ZrO₂/MWCNT"> PVDF/ZrO₂/MWCNT</a> </p> <a href="https://publications.waset.org/abstracts/65263/investigation-of-polymer-composite-for-high-dose-dosimetry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65263.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">288</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">92</span> Determinant Elements for Useful Life in Airports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marcelo%20M%C3%BCller%20Beuren">Marcelo Müller Beuren</a>, <a href="https://publications.waset.org/abstracts/search?q=Jos%C3%A9%20Luis%20Duarte%20Ribeiro"> José Luis Duarte Ribeiro</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies point that Brazilian large airports are not managing their assets efficiently. Therefore, organizations seek improvements to raise their asset’s productivity. Hence, identification of assets useful life in airports becomes an important subject, since its accuracy leads to better maintenance plans and technological substitution, contribution to airport services management. However, current useful life prediction models do not converge in terms of determinant elements used, as they are particular to the studied situation. For that reason, the main objective of this paper is to identify the determinant elements for a useful life of major assets in airports. With that purpose, a case study was held in the key airport of the south of Brazil trough historical data analysis and specialist interview. This paper concluded that most of the assets useful life are determined by technical elements, maintenance cost, and operational costs, while few presented influence of technological obsolescence. As a highlight, it was possible to identify the determinant elements to be considered by a model which objective is to identify the useful life of airport’s major assets. <p
