air transport in Brazil. Total passengers embarked and disembarked were used as a proxy for air transport activity and gross domestic product (GDP) as a proxy for economic development. The test spanned the period from 2000 to 2015 for domestic passenger traffic and from 1995 to 2015 for international traffic. The results confirm the hypothesis that there is cointegration between passenger traffic series and economic development, showing a bi-directional Granger causal relationship between domestic traffic and economic development and unidirectional influence by economic growth on international passenger air transport demand. Variance decomposition of the series showed that domestic air transport was far more important than international transport to promoting economic development in Brazil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20passenger%20transport" title="air passenger transport">air passenger transport</a>, <a href="https://publications.waset.org/abstracts/search?q=cointegration" title=" cointegration"> cointegration</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a>, <a href="https://publications.waset.org/abstracts/search?q=GDP" title=" GDP"> GDP</a>, <a href="https://publications.waset.org/abstracts/search?q=Granger%20causality" title=" Granger causality"> Granger causality</a> </p> <a href="https://publications.waset.org/abstracts/92415/economic-growth-relations-to-domestic-and-international-air-passenger-transport-in-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92415.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">233</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">141</span> Urinalysis by Surface-Enhanced Raman Spectroscopy on Gold Nanoparticles for Different Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20C.%20Pacheco-Londo%C3%B1o">Leonardo C.

In this case, Au-NPs were used for Surface-Enhanced Raman Spectroscopy (SERS) in different diseases' diagnostics, such as Lupus Nephritis (LN), hypertension (H), preeclampsia (PC), and others. This methodology is proposed for the diagnosis of each disease. First, good signals of the different metabolites by SERS were obtained through a mixture of urine samples and Au-NPs. Second, PLS-DA models based on SERS spectra to discriminate each disease were able to differentiate between sick and healthy patients with different diseases. Finally, the sensibility and specificity for the different models were determined in the order of 0.9. On the other hand, a second methodology was developed using machine learning models from all data of the different diseases, and, as a result, a discriminant spectral map of the diseases was generated. These studies were possible thanks to joint research between two university research centers and two health sector entities, and the patient samples were treated with ethical rigor and their consent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SERS" title="SERS">SERS</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman" title=" Raman"> Raman</a>, <a href="https://publications.waset.org/abstracts/search?q=PLS-DA" title=" PLS-DA"> PLS-DA</a>, <a href="https://publications.waset.org/abstracts/search?q=diseases" title=" diseases"> diseases</a> </p> <a href="https://publications.waset.org/abstracts/160183/urinalysis-by-surface-enhanced-raman-spectroscopy-on-gold-nanoparticles-for-different-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160183.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">141</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">140</span> Development of Restricted Formula SAE Intake Manifold Using 1D and Flow Simulations Based on Track Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahil%20Kapahi">Sahil Kapahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Formula SAE competition is characterized by typical track layouts having slaloms, tight corners and short straights, which favor a particular range of engine speed for a given set of gear ratios. Therefore, it is imperative that the power-train is optimized for the corresponding engine rpm band. This paper describes the process of designing, simulating and validating an air intake manifold for an inline four cylinder four-stroke internal combustion gasoline engine based on analysis of required vehicle performance. The requirements for the design of subject intake were set considering the rules of FSAE competitions and analysis of engine performance patterns for typical competition scenarios, carried out using OPTIMUMLAP software. Manifold geometry was optimized using results of air flow simulations performed on ANSYS CFX, and subsequent effect of this geometry on the engine was modeled using 1D simulation on Ricardo WAVE. A design was developed to meet the targeted performance standards in terms of engine torque output and volumetric efficiency. Finally, the intake manifold was manufactured and assembled onto the vehicle, and the engine output of the vehicle with the designed intake was studied using a dynamometer. The results of the dynamometer testing were then validated against predicted values derived from the Ricardo WAVE modeling and benefits to performance of the vehicle were established. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=1%20D%20Simulation" title="1 D Simulation">1 D Simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20flow%20simulation" title=" air flow simulation"> air flow simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=ANSYS%20CFX" title=" ANSYS CFX"> ANSYS CFX</a>, <a href="https://publications.waset.org/abstracts/search?q=four-stroke%20engine" title=" four-stroke engine"> four-stroke engine</a>, <a href="https://publications.waset.org/abstracts/search?q=OPTIMUM%20LAP" title=" OPTIMUM LAP"> OPTIMUM LAP</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20WAVE" title=" Ricardo WAVE"> Ricardo WAVE</a> </p> <a href="https://publications.waset.org/abstracts/75416/development-of-restricted-formula-sae-intake-manifold-using-1d-and-flow-simulations-based-on-track-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75416.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">246</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">139</span> Surface-Enhanced Raman Spectroscopy on Gold Nanoparticles in the Kidney Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20C.%20Pacheco-Londo%C3%B1o">Leonardo C.

In the present study, Au-NPs were employed as substrates for Surface-Enhanced Raman Spectroscopy (SERS) aimed at diagnosing kidney diseases arising from Lupus Nephritis (LN), preeclampsia (PC), and Hypertension (H). Discrimination models were developed for distinguishing patients with and without kidney diseases based on the SERS signals from urine samples by partial least squares-discriminant analysis (PLS-DA). A comparative study of the Raman signals across the three conditions was conducted, leading to the identification of potential metabolite signals. Model performance was assessed through cross-validation and external validation, determining parameters like sensitivity and specificity. Additionally, a secondary analysis was performed using machine learning (ML) models, wherein different ML algorithms were evaluated for their efficiency. Models’ validation was carried out using cross-validation and external validation, and other parameters were determined, such as sensitivity and specificity; the models showed average values of 0.9 for both parameters. Additionally, it is not possible to highlight this collaborative effort involved two university research centers and two healthcare institutions, ensuring ethical treatment and informed consent of patient samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SERS" title="SERS">SERS</a>, <a href="https://publications.waset.org/abstracts/search?q=Raman" title=" Raman"> Raman</a>, <a href="https://publications.waset.org/abstracts/search?q=PLS-DA" title=" PLS-DA"> PLS-DA</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20diseases" title=" kidney diseases"> kidney diseases</a> </p> <a href="https://publications.waset.org/abstracts/174893/surface-enhanced-raman-spectroscopy-on-gold-nanoparticles-in-the-kidney-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174893.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">45</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">138</span> Flow Performance of Hybrid Cement Based Mortars</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Z.%20Abdollahnejad">Z.

Some wastes deserve further studies by the scientific community not only because they are generated in high amount but also because they have a low reuse rate.

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">133</span> Contagion and Stock Interdependence in the BRIC+M Block</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Bucio%20Pacheco">Christian Bucio Pacheco</a>, <a href="https://publications.waset.org/abstracts/search?q=Miriam%20Magnolia%20Sosa%20Castro"> Miriam Magnolia Sosa Castro</a>, <a href="https://publications.waset.org/abstracts/search?q=Mar%C3%ADa%20Alejandra%20Cabello%20Rosales"> María Alejandra Cabello Rosales</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to analyze the contagion effect among the stock markets of the BRIC+M block (Brazil, Russia, India, China plus Mexico).

The act of designing a space dedicated to elderly people goes beyond the concept of well-being and reaches to a point of evaluating and changing the way which society sees this part of the population as well as how it can build a relationship with energy efficiency. In this context, the care facilities for elderly have an extremely important role to provide this infrastructure to the population. A common issue is that, for many times, these facilities face financial issues, and the full operation of the establishment can be impacted. The intention of this work is to develop a project in which the energy efficiency measures can be lived daily and that the residents of the institution can participate actively, directly, or indirectly in the construction of this relationship. The use of energy efficiency strategies should become a natural process when thinking about buildings as it is an essential step to provide increased well-being, climate change mitigation, and cost reduction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title="energy efficiency">energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20comfort" title=" environmental comfort"> environmental comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=long-term%20care%20facility" title=" long-term care facility"> long-term care facility</a>, <a href="https://publications.waset.org/abstracts/search?q=well-being" title=" well-being"> well-being</a> </p> <a href="https://publications.waset.org/abstracts/181637/long-term-care-facility-for-the-elderly-and-its-relationship-with-energy-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181637.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">57</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">127</span> The Regulation on Human Exposure to Electromagnetic Fields for Brazilian Power System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hugo%20Manoel%20Olivera%20Da%20Silva">Hugo Manoel Olivera Da Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Silva%20Th%C3%A9%20Pontes"> Ricardo Silva Thé Pontes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, is presented an analysis of the Brazilian regulation on human exposure to electromagnetic fields, which provides limits to electric fields, magnetic and electromagnetic fields.

Real Time Early Response Systems (RTERSs) incorporate real time information as feedback data for closing control loop and for generating real time situation assessment. A review of the state of the art works that fit the concept of RTERS is presented, and it is found that they are mainly focused on manmade disasters. At the same time, in response phase of natural disaster management many works are involved in creating early warning systems, but just few efforts have been put on deciding what to do once an alarm is activated. In this context a RTERS arises as a useful tool for supporting people in their decision making process during natural disasters after an event is detected, and also as an innovative context for applying well-known automation technologies and automatic control concepts and tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disaster%20management" title="disaster management">disaster management</a>, <a href="https://publications.waset.org/abstracts/search?q=emergency%20response%20system" title=" emergency response system"> emergency response system</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20disasters" title=" natural disasters"> natural disasters</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time" title=" real time"> real time</a> </p> <a href="https://publications.waset.org/abstracts/26120/design-of-real-time-early-response-systems-for-natural-disaster-management-based-on-automation-and-control-technologies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26120.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">444</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">125</span> Preparation on Sentimental Analysis on Social Media Comments with Bidirectional Long Short-Term Memory Gated Recurrent Unit and Model Glove in Portuguese</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Alfredo%20Mendoza">Leonardo Alfredo Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Cristian%20Munoz"> Cristian Munoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Marco%20Aurelio%20Pacheco"> Marco Aurelio Pacheco</a>, <a href="https://publications.waset.org/abstracts/search?q=Manoela%20Kohler"> Manoela Kohler</a>, <a href="https://publications.waset.org/abstracts/search?q=Evelyn%20%20Batista"> Evelyn Batista</a>, <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20Moura"> Rodrigo Moura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural Language Processing (NLP) techniques are increasingly more powerful to be able to interpret the feelings and reactions of a person to a product or service.

The analyzed samples came from the subgrade layer of a highway that connects the cities of Muniches and Yurimaguas in Loreto, Peru. The material in this area usually has properties such as low support index, medium to high plasticity, and other characteristics that make it considered a ‘problematic’ soil due to factors such as climate, humidity, and geographical location. In addition, PET fibers are obtained from the decomposition of plastic bottles that are polluting agents with a high production rate in our country; in that sense, their use in a construction process represents a considerable reduction in environmental impact. Moreover, to perform a precise analysis of the behavior of this soil mixed with PET, tests such as the hydrometer test, Proctor and CBR with 15%, 10%, 5%, 4%, 3%, and 1% of PET with respect to the mass of the sample of natural soil were carried out. The results show that when a low percentage of PET is used, the support index increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact" title="environmental impact">environmental impact</a>, <a href="https://publications.waset.org/abstracts/search?q=geotechnics" title=" geotechnics"> geotechnics</a>, <a href="https://publications.waset.org/abstracts/search?q=PET" title=" PET"> PET</a>, <a href="https://publications.waset.org/abstracts/search?q=silty%20clay%20soil" title=" silty clay soil"> silty clay soil</a> </p> <a href="https://publications.waset.org/abstracts/139463/bearing-capacity-improvement-in-a-silty-clay-soil-with-crushed-polyethylene-terephthalate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139463.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">237</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">123</span> Wireless Sensor Networks for Water Quality Monitoring: Prototype Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cesar%20Eduardo%20Hern%C3%A1ndez%20Curiel">Cesar Eduardo Hernández Curiel</a>, <a href="https://publications.waset.org/abstracts/search?q=Victor%20Hugo%20Ben%C3%ADtez%20Baltazar"> Victor Hugo Benítez Baltazar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jes%C3%BAs%20Horacio%20Pacheco%20Ram%C3%ADrez"> Jesús Horacio Pacheco Ramírez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is devoted to present the advances in the design of a prototype that is able to supervise the complex behavior of water quality parameters such as pH and temperature, via a real-time monitoring system. The current water quality tests that are performed in government water quality institutions in Mexico are carried out in problematic locations and they require taking manual samples. The water samples are then taken to the institution laboratory for examination. In order to automate this process, a water quality monitoring system based on wireless sensor networks is proposed. The system consists of a sensor node which contains one pH sensor, one temperature sensor, a microcontroller, and a ZigBee radio, and a base station composed by a ZigBee radio and a PC. The progress in this investigation shows the development of a water quality monitoring system. Due to recent events that affected water quality in Mexico, the main motivation of this study is to address water quality monitoring systems, so in the near future, a more robust, affordable, and reliable system can be deployed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pH%20measurement" title="pH measurement">pH measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20monitoring" title=" water quality monitoring"> water quality monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title=" wireless sensor networks"> wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=ZigBee" title=" ZigBee"> ZigBee</a> </p> <a href="https://publications.waset.org/abstracts/43281/wireless-sensor-networks-for-water-quality-monitoring-prototype-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43281.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">404</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">122</span> The Design of the Questionnaire of Attitudes in Physics Teaching</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Merlo">Ricardo Merlo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Attitude is a hypothetical construct that can be significantly measured to know the favorable or unfavorable predisposition that students have towards the teaching of sciences such as Physics.

Then, in this work, a methodology of attitude questionnaire construction process was proposed that allowed the teacher to design and validate the measurement instrument for different subjects of Physics at the university level developed in the classroom according to the weight considered to the affective, knowledge, and behavioural dimensions.

Since the majority of the existent infrastructures are Portland cement concrete based this means that concrete infrastructure rehabilitation is a hot issue to be dealt with. Geopolymers are novel inorganic binders with high potential to replace Portland cement based ones. So far very few studies in the geopolymer field have addressed the rehabilitation of deteriorated concrete structures. This paper discloses results of an investigation concerning the development geopolymeric repair mortars. The mortars are based on Tunisian natural clay plus calcium hydroxide, sodium silicate and sodium hydroxide. Results show that the geopolymeric mortar has a high compressive strength and a lower unrestrained shrinkage performance as long as partial replacement by metakaolin is carried out. The results also show that Tunisian calcined clay based mortars have hydration products with typical geopolymeric phases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geopolymeric%20mortars" title="geopolymeric mortars">geopolymeric mortars</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure%20repair" title=" infrastructure repair"> infrastructure repair</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a> </p> <a href="https://publications.waset.org/abstracts/38503/mechanical-performance-of-geopolymeric-mortars-based-on-natural-clay-fly-ash-and-metakaolin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38503.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">329</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> An Architectural Model of Multi-Agent Systems for Student Evaluation in Collaborative Game Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monica%20Hoeldtke%20Pietruchinski">Monica Hoeldtke Pietruchinski</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Ricardo%20Pimentel"> Andrey Ricardo Pimentel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The teaching of computer programming for beginners has been presented to the community as a not simple or trivial task.

Within this framework, a test with 30 items was designed and administered to 800 volunteer first-year university students of natural and exact sciences. Based on a randomized pilot test, it was validated with Cronbach's Alpha coefficient. Subsequently, the descriptive statistics of the sample used allowed us to observe the preponderance of the dimensions that constitute the attitude construct.

To evaluate the quality of this proposed model, experiments were performed by the use of two sets containing new relations, being one generated automatically and the other manually mapped by the domain expert. The applied evaluation metrics were precision, recall, f-score, and confidence interval. The results obtained demonstrate that the applied method in the field of Oil Production and Extraction (E&P) is effective, which suggests that it can be used to improve the quality of terminological mappings.

Among the several risk factors for septic arthritis, such as age, rheumatoid arthritis, recent surgery, or skin infection, diabetes mellitus can sometimes be the main risk factor. Staphylococcus aureus is the most common pathogen isolated in septic arthritis; however, it is uncommon in monomicrobial necrotizing fasciitis. Objectives: A case report of concomitant septic arthritis and necrotizing fasciitis in a patient with undiagnosed diabetes based on clinical history. Study Design & Methods: We report a case of a 58-year-old Portuguese previously healthy man who presented to the emergency department with fever and left knee swelling and pain for two days. The blood work revealed ketonemia of 6.7 mmol/L and glycemia of 496 mg/dL. The vital signs were significant for a temperature of 38.5 ºC and 123 bpm of heart rate. The left knee had edema and inflammatory signs. Computed tomography of the left knee showed diffuse edema of the subcutaneous cellular tissue and soft tissue air bubbles. A diagnosis of septic arthritis and necrotising fasciitis was made. He was taken to the operating room for surgical debridement. The samples collected intraoperatively were sent for microbiological analysis, revealing infection by multi-sensitive Staphylococcus aureus. Given this result, the empiric flucloxacillin (500 mg IV) and clindamycin (1000 mg IV) were maintained for 3 weeks. On the seventh day of hospitalization, there was a significant improvement in subcutaneous and musculoskeletal tissues. After two weeks of hospitalization, there was no purulent content and partial closure of the wounds was possible. After 3 weeks, he was switched to oral antibiotics (flucloxacillin 500 mg). A week later, a urinary infection by Pseudomonas aeruginosa was diagnosed and ciprofloxacin 500 mg was administered for 7 days without complications. After 30 days of hospital admission, the patient was discharged home and recovered. Results: The final diagnosis of concomitant septic arthritis and necrotizing fasciitis was made based on the imaging findings, surgical exploration and microbiological tests results. Conclusions: Early antibiotic administration and surgical debridement are key in the management of septic arthritis and necrotizing fasciitis. Furthermore, risk factors control (euglycemic blood glucose levels) must always be taken into account given the crucial role in the patient's recovery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=septic%20arthritis" title="septic arthritis">septic arthritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Necrotizing%20fasciitis" title=" Necrotizing fasciitis"> Necrotizing fasciitis</a>, <a href="https://publications.waset.org/abstracts/search?q=diabetes" title=" diabetes"> diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=Staphylococcus%20Aureus" title=" Staphylococcus Aureus"> Staphylococcus Aureus</a> </p> <a href="https://publications.waset.org/abstracts/158831/staphylococcus-aureus-septic-arthritis-and-necrotizing-fasciitis-in-a-patient-with-undiagnosed-diabetes-mellitus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158831.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">315</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">115</span> Low-Cost VoIP University Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20Henrique%20Rodrigues%20de%20Oliveira">Carlos Henrique Rodrigues de Oliveira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Carlos%20Costa%20Fonseca"> Luis Carlos Costa Fonseca</a>, <a href="https://publications.waset.org/abstracts/search?q=Caio%20de%20Castro%20Torres"> Caio de Castro Torres</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gusm%C3%A3o%20Pereira"> Daniel Gusmão Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Ricardo%20Souza%20Ripardo"> Luiz Ricardo Souza Ripardo</a>, <a href="https://publications.waset.org/abstracts/search?q=Magno%20Castro%20Moraes"> Magno Castro Moraes</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Paula%20Ferreira%20Costa"> Ana Paula Ferreira Costa</a>, <a href="https://publications.waset.org/abstracts/search?q=Luiz%20Carlos%20Chaves%20Lima%20Junior"> Luiz Carlos Chaves Lima Junior</a>, <a href="https://publications.waset.org/abstracts/search?q=Aurelianny%20Almeida%20da%20Cunha"> Aurelianny Almeida da Cunha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> VoIP University is a communication solution based on the IP protocol.

A financial analysis revealed that annual spending on telephone bills decreased by more than 97 %. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=VoIP%20eTec" title="VoIP eTec">VoIP eTec</a>, <a href="https://publications.waset.org/abstracts/search?q=VoIP%20UEMA" title=" VoIP UEMA"> VoIP UEMA</a>, <a href="https://publications.waset.org/abstracts/search?q=VoIP%20University" title=" VoIP University"> VoIP University</a>, <a href="https://publications.waset.org/abstracts/search?q=VoIP%20Valen" title=" VoIP Valen"> VoIP Valen</a> </p> <a href="https://publications.waset.org/abstracts/182442/low-cost-voip-university-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182442.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">114</span> A Step Towards Automating the Synthesis of a Scene Script</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Americo%20Pereira">Americo Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Carvalho"> Ricardo Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Carvalho"> Pedro Carvalho</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Corte-Real"> Luis Corte-Real</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Generating 3D content is a task mostly done by hand. It requires specific knowledge not only on how to use the tools for the task but also on the fundamentals of a 3D environment. In this work, we show that automatic generation of content can be achieved, from a scene script, by leveraging existing tools so that non-experts can easily engage in a 3D content generation without requiring vast amounts of time in exploring and learning how to use specific tools. This proposal carries several benefits, including flexible scene synthesis with different levels of detail. Our preliminary results show that the automatically generated content is comparable to the content generated by users with low experience in 3D modeling while vastly reducing the amount of time required for the generation and adds support to implement flexible scenarios for visual scene visualization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20virtualization" title="3D virtualization">3D virtualization</a>, <a href="https://publications.waset.org/abstracts/search?q=multimedia" title=" multimedia"> multimedia</a>, <a href="https://publications.waset.org/abstracts/search?q=scene%20script" title=" scene script"> scene script</a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/136994/a-step-towards-automating-the-synthesis-of-a-scene-script" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136994.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">266</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">113</span> Determination of the Gain in Learning the Free-Fall Motion of Bodies by Applying the Resource of Previous Concepts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ricardo%20Merlo">Ricardo Merlo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we analyzed the different didactic proposals for teaching about the free fall motion of bodies available online. An important aspect was the interpretation of the direction and sense of the acceleration of gravity and of the falling velocity of a body, which is why we found different applications of the Cartesian reference system used and also different graphical presentations of the velocity as a function of time and of the distance traveled vertically by the body in the period of time that it was dropped from a height h0. In this framework, a survey of previous concepts was applied to a voluntary group of first-year university students of an Engineering degree before and after the development of the class of the subject in question. Then, Hake's index (0.52) was determined, which resulted in an average learning gain from the meaningful use of the reference system and the respective graphs of v=ƒ (t) and h=ƒ (t). <p
