It can be observed by the growth of the local pet industry. But the essentials of lifestyle of the urban people which is restricted by time and work might not allow the owner to take care of the pet properly. So this article will be about how to develop the prototype of pet care monitoring with Arduino Microcontroller. This prototype can be used to monitor the pet and its environment around the pet such as temperature (both pet’s temperature and outside temperature), humidity, food’s quantity, air’s quality and also be able to reduce the stress of the pet. This prototype can report the result back to the owner via online-channel such as website etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pet%20care" title="pet care">pet care</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino%20Microcontroller" title=" Arduino Microcontroller"> Arduino Microcontroller</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype" title=" prototype"> prototype</a> </p> <a href="https://publications.waset.org/abstracts/12578/pet-care-monitoring-with-arduino" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12578.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">358</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">621</span> Educatronic Prototype for Learning Geometry, Based on a Multitouch Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vicario%20Marina">Vicario Marina</a>, <a href="https://publications.waset.org/abstracts/search?q=Bustos%20Freddy"> Bustos Freddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Olivares%20Jes%C3%BAs"> Olivares Jesús</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B3mez%20Pilar"> Gómez Pilar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a didactic model and a tool as educational resources to support the learning of geometry; they focus on topics difficult to understand.

Initially, the transmitter and receiver circuits were programmed in Arduino so that the data would travel by light pulses in the aforementioned code. To obtain the results of the underwater communication, two scenarios were chosen (fish tank and swimming pool), where the power value of the received signal was calculated from its peak-to-peak voltage using the Oscilloscope equipment (ESPOCH). Finally, it was concluded that the maximum communication range of this prototype is 12m underwater, and it was observed that the power decreases as the distance increases. However, this prototype still needs to improve communication so that the information is not distorted or lost when there is movement and dispersion of the water. It is hoped that it will form the basis for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=prototype" title="prototype">prototype</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater" title=" underwater"> underwater</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a>, <a href="https://publications.waset.org/abstracts/search?q=power" title=" power"> power</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage" title=" voltage"> voltage</a>, <a href="https://publications.waset.org/abstracts/search?q=distance" title=" distance"> distance</a> </p> <a href="https://publications.waset.org/abstracts/171122/transmission-of-ascii-code-messages-using-a-high-power-50mw-underwater-laser-communication-prototype-in-two-controlled-scenarios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171122.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">89</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">618</span> The Development of the Prototype of Bamboo Shading Device </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuanwan%20Tuaycharoen">Nuanwan Tuaycharoen</a>, <a href="https://publications.waset.org/abstracts/search?q=Wanarat%20Konisranukul"> Wanarat Konisranukul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main aim of this research was to investigate the prototype of bamboo shading device. There were two objectives of this study. The first objective was to investigate the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle and fungi. The second aim of this study was to develop a prototype of bamboo shading device. The study of the effect of non-chemical treatments on damage of bamboo shading device by powder-post beetle in laboratory showed that, among seven treatments tested, wood vinegar treatment can protect powder-post beetle better than the original method up to 92.91%. It was also found that wood vinegar treatment can show the best performance in fungi protection and work better than the original method up to 40%. The second experiment was carried out by constructing four bamboo shading devices and installing them on a building for 28 days. All aspects of shading device were investigated in terms of their beauty, durability, and ease of construction and assembly. The final prototype was developed from the lessons drawn from these tested options. In conclusion this study showed the effectiveness of some natural preservatives against insect and fungi damage. It also illustrated the characteristics of the prototype of bamboo shading device that can constructed by rural workers within one week. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo" title="bamboo">bamboo</a>, <a href="https://publications.waset.org/abstracts/search?q=shading%20device" title=" shading device"> shading device</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conservation" title=" energy conservation"> energy conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20material" title=" alternative material"> alternative material</a> </p> <a href="https://publications.waset.org/abstracts/26400/the-development-of-the-prototype-of-bamboo-shading-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26400.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">378</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">617</span> Experimental Study on Drying Parameters of Freeze Drying Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Osman%20Sui%C3%A7mez">Ali Osman Suiçmez</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Deniz"> Emrah Deniz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, control experiments were made on a freeze drying system of which were built a prototype.

The aim is to examine several principles and guidelines in obtaining evidence from observing how users interact with the targeted product and interviewing them to acquire deep insights of their needs. With the help of Quality Function Deployment (QFD), the identified needs of the users while interacting with the product were ranked using the normalised weighting approach. Furthermore, a low fidelity prototype of the alarm clock is developed with a view of addressing the identified needs of the users. Finally, the low fidelity prototype design was evaluated with two design prototypes already existing in the market through a study involving 30 participants.

The activities that describe the behavior of the most of activities in multi-storey buildings are scheduled using the developed approach. The prototype combines three methods to attain the optimized planning. The methods include Critical Path Method (CPM), Gantt and Line of Balance (LOB). The developed prototype; POTER is used to schedule repetitive and non-repetitive activities with respect to all constraints that can be automatically generated using a generic database. The prototype uses the method of genetic algorithms for optimizing the planning process. As a result, this approach enables contracting organizations to evaluate various planning solutions that are calculated, tested and classified by POTER to attain an optimal time-cost equilibrium according to their own criteria of time or coast. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planning%20scheduling" title="planning scheduling">planning scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithms" title=" genetic algorithms"> genetic algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=repetitive%20activity" title=" repetitive activity"> repetitive activity</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title=" construction management"> construction management</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20duration" title=" project duration"> project duration</a> </p> <a href="https://publications.waset.org/abstracts/42082/scheduling-of-repetitive-activities-for-height-rise-buildings-optimisation-by-genetic-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42082.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">308</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">613</span> Developing Ergonomic Prototype Testing Method for Manual Material Handling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Nugroho%20Doyo%20Yekti">Yusuf Nugroho Doyo Yekti</a>, <a href="https://publications.waset.org/abstracts/search?q=Budi%20Praptono"> Budi Praptono</a>, <a href="https://publications.waset.org/abstracts/search?q=Fransiskus%20Tatas%20Dwi%20Atmaji"> Fransiskus Tatas Dwi Atmaji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no ergonomic prototype testing method for manual material handling yet.

The methods used in the tests are Rapid Entire Body Assessment (REBA), Recommended Weight Limit (RWL), and Cardiovascular Load (%CVL) other than usability test and questionnaire. The proposed testing methods cover comprehensive ergonomic aspects, i.e. physical aspect, mental aspect, emotional aspects of human. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ergonomic" title="ergonomic">ergonomic</a>, <a href="https://publications.waset.org/abstracts/search?q=manual%20material%20handling" title=" manual material handling"> manual material handling</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype%20testing" title=" prototype testing"> prototype testing</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a> </p> <a href="https://publications.waset.org/abstracts/35664/developing-ergonomic-prototype-testing-method-for-manual-material-handling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35664.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">517</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">612</span> Assessment of the Remains in Historic Urban Area Based on Spatial Prototype: Case Study on Jingmen City, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guangtong%20Xu">Guangtong Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi%20He"> Yi He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Like most historic and cultural cities in China, the historic urban area of Jingmen city is facing a typical spatial problem of fragmentation and fuzzification. This study focuses on exploring a method for evaluating the existing values of historic urban area based on spatial prototype, a concept introduced into urban morphology from 'Archetype' in architectural typology. As the spatial elements and built-up relationship of historic city, spatial prototype has habitual structural characteristics and formal modulus. It is the inherent logic and order rules behind the scattered historic environment, providing a clue to understand the spatial characteristics and a basis for guiding the construction and conservation in historic urban areas. Three criteria, the resolution of historical elements, the completeness of historical structure and the renewal potential of associated land, were selected to construct the integrated assessment system. These three dimensions are linked to the spatial prototype and its constituent elements, as well as the transformation relationship in ancient and present day. The results showed that historic urban areas have changed from a holistic city to different existing types dominated by their historic structure elements. It is necessary to improve the pertinence of planning strategies and develop diversified management measures in the conservation scope of historic urban area. Moreover, a constructive-conservation strategy should be put forward to enhance the integrity of historic urban area based on the trace of spatial prototype and evaluation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructive%20conservation" title="constructive conservation">constructive conservation</a>, <a href="https://publications.waset.org/abstracts/search?q=existing%20value" title=" existing value"> existing value</a>, <a href="https://publications.waset.org/abstracts/search?q=historic%20urban%20area" title=" historic urban area"> historic urban area</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20prototype" title=" spatial prototype"> spatial prototype</a> </p> <a href="https://publications.waset.org/abstracts/104240/assessment-of-the-remains-in-historic-urban-area-based-on-spatial-prototype-case-study-on-jingmen-city-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104240.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">169</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">611</span> Prototype for Measuring Blue Light Protection in Sunglasses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20D.%20Loureiro">A.

Ventura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exposure to high-energy blue light has been strongly linked to the development of some eye diseases, such as age-related macular degeneration. Over the past few years, people have become more and more concerned about eye damage from blue light and how it can be prevented. We developed a prototype that allows users to self-check the blue light protection of their sunglasses and determines if the protection is adequate. Weighting functions approximating those defined in ISO 12312-1 were used to measure the luminous transmittance and blue light transmittance of sunglasses. The blue light transmittance value must be less than 1.2 times the luminous transmittance to be considered adequate. The prototype consists of a Golden Dragon Ultra White LED from OSRAM and a TCS3472 photodetector from AMS TAOS. Together, they provide four transmittance values weighted with different functions. These four transmittance values were then linearly combined to produce transmittance values with weighting functions close to those defined in ISO 12312-1 for luminous transmittance and for blue light transmittance. To evaluate our prototype, we used a VARIAN Cary 5000 spectrophotometer, a gold standard in the field, to measure the luminous transmittance and the blue light transmittance of 60 sunglasses lenses. (and Bland-Altman analysis was performed) Bland-Altman analysis was performed and showed non-significant bias and narrow 95% limits of agreement within predefined tolerances for both luminous transmittance and blue light transmittance. The results show that the prototype is a viable means of providing blue light protection information to the general public and a quick and easy way for industry and retailers to test their products. In addition, our prototype plays an important role in educating the public about a feature to look for in sunglasses before purchasing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blue%20light" title="blue light">blue light</a>, <a href="https://publications.waset.org/abstracts/search?q=sunglasses" title=" sunglasses"> sunglasses</a>, <a href="https://publications.waset.org/abstracts/search?q=eye%20protective%20devices" title=" eye protective devices"> eye protective devices</a>, <a href="https://publications.waset.org/abstracts/search?q=transmittance%20measurement" title=" transmittance measurement"> transmittance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=standards" title=" standards"> standards</a>, <a href="https://publications.waset.org/abstracts/search?q=ISO%2012312-1" title=" ISO 12312-1"> ISO 12312-1</a> </p> <a href="https://publications.waset.org/abstracts/163500/prototype-for-measuring-blue-light-protection-in-sunglasses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163500.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">164</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">610</span> Analysis and Comparison of Prototypes of an Ergometric Step in a Multidisciplinary Design Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20B.%20Ricardo%20De%20Oliveira">M.

Furthermore, prototyping consists in an important stage in product development and results in better team communication, decision making, testing and problem solving through feedback. Although there are several methods of prototyping suggested by recent studies for designers to choose from, some methods present different advantages, such as cost and time reduction, performance and fidelity, which should be taken in account during a product development project. In this multidisciplinary study, involving areas of physiotherapy, engineering and computer science (hardware and software), we compared four developed prototypes of an ergometric step: a virtual prototype, a 3D printed prototype, a bricolage prototype and a prototype manufactured by a third-party company. These prototypes were evaluated in a comparative-qualitative approach for their contribution to the concept’s maturation of the product, the different prototyping methods used and the advantages and disadvantages of each one based on the product’s design specifications (performance, safety, materials, cost, maintenance, usability, ergonomics and portability). Our results indicated that despite prototypes show overall advantages, all of them have limitations, thus being crucial to have different methods of testing and interacting with the product. Additionally, virtual and 3D printed prototypes were essential at early stages of the project due to their low-cost and high-fidelity representation of the product, while the prototype manufactured by a third-party company and bricolage prototype introduced functional tests in real scenarios, allowing more detailed evaluations. This study also resulted in a patent for an ergometric step. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Product%20Design" title="Product Design">Product Design</a>, <a href="https://publications.waset.org/abstracts/search?q=Product%20Development" title=" Product Development"> Product Development</a>, <a href="https://publications.waset.org/abstracts/search?q=Prototypes" title=" Prototypes"> Prototypes</a>, <a href="https://publications.waset.org/abstracts/search?q=Step" title=" Step"> Step</a> </p> <a href="https://publications.waset.org/abstracts/124019/analysis-and-comparison-of-prototypes-of-an-ergometric-step-in-a-multidisciplinary-design-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124019.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">117</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">609</span> Development of Anterior Lumbar Interbody Fusion (ALIF) Peek Cage Based on the Korean Lumbar Anatomical Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20Soo%20Chon">Chang Soo Chon</a>, <a href="https://publications.waset.org/abstracts/search?q=Cheol%20Woong%20Ko"> Cheol Woong Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Sung%20Kim"> Han Sung Kim </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to develop an anterior lumbar interbody fusion (ALIF) PEEK cage suitable for Korean people.

A team of Purdue University School of Aviation and Transportation Technology (SATT) faculty and students have partnered to investigate the characteristics of 3D printed recycled carbon fiber. A prototype of a 3D printed recycled carbon fiber part was provided by an industry partner and different sections of the prototype were used to create specimens. A furnace was utilized in order to remove the polymer from the specimens and the specimen’s fiber content and fiber length was calculated from the remaining fibers. A differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) test was also conducted on the 3D printed recycled carbon fiber prototype in order to determine the prototype’s degree of cure at different locations.

The present work was planned to develop a low-cost, feasible prototype, CyanoClean, for the growth of a cyanobacterial consortium for the removal of arsenic (As) from water. The cyanobacterial consortium consisting of Oscillatoria, Phormidiumand Gloeotrichiawas used, and the conditions for optimal growth of the consortium were standardized. A pH of 7.6, initial cyanobacterial biomass of 10 g/L, and arsenite [As(III)] and arsenate [As(V)] concentration of 400 μΜand 600 μM, respectively, were found to be suitable. The CyanoClean prototype was designed with acrylic sheet and had arrangements for optimal cyanobacterial growth in natural sunlight and also in artificial light. The As removal experiments in concentration- and duration-dependent manner demonstrated removal of up to 39-69% and 9-33% As respectively from As(III) and As(V)-contaminated water. In field testing of CyanoClean, natural As-contaminated groundwater was used, and As reduction was monitored when a flow rate of 3 L/h was maintained. In a field experiment, As concentration in groundwater was found to reduce from 102.43 μg L⁻¹ to <10 μg L⁻¹ after 6 h in natural sunlight. However, in shaded conditions under artificial light, the same result was achieved after 9 h.

Every dam has a water conveyance system, such as a spillway, providing the safe discharge of catastrophic floods when necessary. Spillway design has historically been investigated in laboratory research owing to the absence of suitable full-scale flow monitoring equipment and safety problems. Prototype measurements of aerated flows are urgently needed to quantify projected scale effects and provide missing validation data for design guidelines and numerical simulations. In this work, an image-based investigation of free-surface flows on a tiered spillway was undertaken at the laboratory (fixed camera installation) and prototype size (drone video) (drone footage) (drone footage). The drone videos were generated using data from citizen science. Analyses permitted the measurement of the free-surface aeration inception point, air-water surface velocities, fluctuations, and residual energy at the chute's downstream end from a remote site. The prototype observations offered full-scale proof of concept, while laboratory results were efficiently confirmed against invasive phase-detection probe data. This paper stresses the efficacy of image-based analyses at prototype spillways. It highlights how citizen science data may enable academics better understand real-world air-water flow dynamics and offers a framework for a small collection of long-missing prototype data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title="remote sensing">remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=aerated%20flows" title=" aerated flows"> aerated flows</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20dams" title=" large dams"> large dams</a>, <a href="https://publications.waset.org/abstracts/search?q=proof%20of%20concept" title=" proof of concept"> proof of concept</a>, <a href="https://publications.waset.org/abstracts/search?q=dam%20spillways" title=" dam spillways"> dam spillways</a>, <a href="https://publications.waset.org/abstracts/search?q=air-water%20flows" title=" air-water flows"> air-water flows</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype%20operation" title=" prototype operation"> prototype operation</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=inception%20point" title=" inception point"> inception point</a>, <a href="https://publications.waset.org/abstracts/search?q=optical%20flow" title=" optical flow"> optical flow</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence" title=" turbulence"> turbulence</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20energy" title=" residual energy"> residual energy</a> </p> <a href="https://publications.waset.org/abstracts/166373/remote-sensing-of-aerated-flows-at-large-dams-proof-of-concept" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166373.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">92</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">601</span> Development of Star Tracker for Satellite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Yelubayev">S.

Klaten Regency, located on the slopes of Mount Merapi along the Woro River in Kemalang District, has potential Class C excavation materials such as sand and stone. Data from the Klaten Regency Transportation Department indicates that ODOL violations account for 72%, while non-violating vehicles make up only 28%. ODOL involves modifying factory-standard vehicles beyond the limits specified in the Type Test Registration Certificate (SRUT) to save costs and travel time. This study aims to develop a prototype ‘Sabrang’ monitoring system based on Arduino Mega to control and monitor ODOL freight transportation in the mining of Class C excavation materials in Klaten Regency. The prototype is designed to automatically measure the dimensions and weight of objects using a microcontroller. The data analysis techniques used in this study include the Normality Test and Paired T-Test, comparing sensor measurement results on scaled objects. The study results indicate differences in measurement validation under room temperature and ambient temperature conditions. Measurements at room temperature showed that the majority of H0 was accepted, meaning there was no significant difference in measurements when the prototype tool was used. Conversely, measurements at ambient temperature showed that the majority of H0 was rejected, indicating a significant difference in measurements when the prototype tool was used. In conclusion, the ‘Sabrang’ monitoring system prototype is effective for controlling ODOL, although measurement results are influenced by temperature conditions. This study is expected to assist in the monitoring and control of ODOL, thereby enhancing traffic safety and road infrastructure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=over%20dimension%20over%20loading" title="over dimension over loading">over dimension over loading</a>, <a href="https://publications.waset.org/abstracts/search?q=prototype" title=" prototype"> prototype</a>, <a href="https://publications.waset.org/abstracts/search?q=microcontroller" title=" microcontroller"> microcontroller</a>, <a href="https://publications.waset.org/abstracts/search?q=Arduino" title=" Arduino"> Arduino</a>, <a href="https://publications.waset.org/abstracts/search?q=normality%20test" title=" normality test"> normality test</a>, <a href="https://publications.waset.org/abstracts/search?q=paired%20t-test" title=" paired t-test"> paired t-test</a> </p> <a href="https://publications.waset.org/abstracts/188384/prototype-of-over-dimension-over-loading-odol-freight-transportation-monitoring-system-based-on-arduino-mega-sabrang-a-case-study-in-klaten-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/188384.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">34</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">599</span> Poli4SDG: An Application for Environmental Crises Management and Gender Support</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Angelica%20S.%20Valeriani">Angelica S.

Sustainable Development Goals (SDGs), promoted by United Nations, aim to front issues related to climate change, among others. In particular, the project CROWD4SDG focuses on a bunch of SDGs since it promotes environmental activities and climate-related issues. In this context, we developed a prototype of an application, under advanced development considering web design, that focuses on SDG 13 (SDG on climate action) by providing users with useful instruments to face environmental crises and climate-related disasters. Our prototype is thought and structured for both web and mobile development. The main goal of the application, POLI4SDG, is to help users to get through emergency services. To this extent, an organized overview and classification prove to be very effective and helpful to people in need. A careful analysis of data related to environmental crises prompted us to integrate the user contribution, i.e., exploiting a core principle of Citizen Science, into the realization of a public catalog, available for consulting and organized according to typology and specific features. In addition, gender equality and opportunity features are considered in the prototype in order to allow women, often the most vulnerable category, to have direct support. The overall description of the application functionalities is detailed. Moreover, the implementation features and properties of the prototype are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crowdsourcing" title="crowdsourcing">crowdsourcing</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=SDG" title=" SDG"> SDG</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</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=gender%20equality" title=" gender equality"> gender equality</a> </p> <a href="https://publications.waset.org/abstracts/154178/poli4sdg-an-application-for-environmental-crises-management-and-gender-support" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154178.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">598</span> Developing a Comprehensive Model for the Prevention of Tension Neck Syndrome: A Focus on Musculoskeletal Disorder Prevention Strategies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Behnaz%20Sohani">Behnaz Sohani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ifeoluwa%20Joshua%20Adigun"> Ifeoluwa Joshua Adigun</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Rahmani"> Amir Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Goher"> Khaled Goher</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper provides initial results on the eﬃcacy of the designed ergonomic-oriented neck support to mitigate and alleviate tension neck syndrome musculoskeletal disorder.

The method of placement of the maturity sensors determines their number required for a certain frame of a monolithic building. Previous studies weakly describe this aspect, giving only logical assumptions. This paper proposes a cheap prototype of an embedded wireless sensor for monitoring concrete structures, as well as an alternative strategy for placing sensors based on the transitional boundaries of the temperature distribution of concrete curing, which were determined by building a heat map of the temperature distribution, where unknown values are calculated by the method of inverse distance weighing. The developed prototype can simultaneously measure temperature and relative humidity over a smartphone-controlled time interval. It implements a maturity method to assess the in-situ strength of concrete, which is considered an alternative to the traditional shock impulse and compression testing method used in Kazakhstan. The prototype was tested in laboratory and field conditions. The tests were aimed at studying the effect of internal and external temperature and relative humidity on concrete's strength gain. Based on an experimentally poured concrete slab with randomly integrated maturity sensors, it was determined that the transition boundaries form elliptical forms. Temperature distribution over the largest diameter of the ellipses was plotted, resulting in correct and inverted parabolas. As a result, the distance between the closest opposite crossing points of the parabolas is accepted as the maximum permissible step for setting the maturity sensors. The proposed placement strategy can be applied to sensors that measure various continuous phenomena such as relative humidity. Prototype testing has also revealed Bluetooth inconvenience due to weak signal and inability to access multiple prototypes simultaneously. For this reason, further prototype upgrades are planned in future work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20map" title="heat map">heat map</a>, <a href="https://publications.waset.org/abstracts/search?q=placement%20strategy" title=" placement strategy"> placement strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%20and%20relative%20humidity" title=" temperature and relative humidity"> temperature and relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20embedded%20sensor" title=" wireless embedded sensor"> wireless embedded sensor</a> </p> <a href="https://publications.waset.org/abstracts/129345/development-of-the-maturity-sensor-prototype-and-method-of-its-placement-in-the-structure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129345.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">177</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">596</span> Design and Manufacture of an Autonomous Agricultural Robot for Pesticide Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Caner%20Koc">Caner Koc</a>, <a href="https://publications.waset.org/abstracts/search?q=Dilara%20Gerdan%20Koc"> Dilara Gerdan Koc</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Saka"> Emrah Saka</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20Ibrahim%20Karagol"> H.

In this study, an electric, electrostatically charged, autonomous agricultural robot was developed, modeled, and prototyped and manufactured. It allows for sensitive pesticide applications with variable levels, has controllable spray nozzles, and uses camera distance sensors to detect and spray into tree canopies. The created prototype was produced with flexibility in mind. Two stages of prototype manufacture were completed. The initial stage involved designing and producing the flexible primary body of the autonomous vehicle. Detachable hanger assemblies are employed so that the main body robot can perform a variety of agricultural tasks. The design of the spraying devices and their fitting to the autonomous vehicle was completed as the second stage of the prototype. The built prototype spraying robot's itinerary was planned using the free, open-source program Mission Planner. PX4, telemetry, and RTK GPS are used to maneuver the autonomous car along the designated path. To avoid potential obstructions, the robot uses ultrasonic and lidar sensors. The developed autonomous vehicle's energy needs are intended to be met entirely by electric batteries. In the event that the batteries run out of power, the sockets are set up to be recharged both by using the generator and the main power source through the specifically constructed panel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autonomous%20agricultural%20robot" title="autonomous agricultural robot">autonomous agricultural robot</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide" title=" pesticide"> pesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20farming" title=" smart farming"> smart farming</a>, <a href="https://publications.waset.org/abstracts/search?q=spraying" title=" spraying"> spraying</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20rate%20application" title=" variable rate application"> variable rate application</a> </p> <a href="https://publications.waset.org/abstracts/165713/design-and-manufacture-of-an-autonomous-agricultural-robot-for-pesticide-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165713.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">84</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">595</span> A Four Free Element Radiofrequency Coil with High B₁ Homogeneity for Magnetic Resonance Imaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Al-Snaie">Khalid Al-Snaie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the design and the testing of a symmetrical radiofrequency prototype coil with high B₁ magnetic field homogeneity are presented.

Electrical modeling of the probe, including all couplings, is used to ensure these requirements. Results of comparison tests, in free space and in a spectro-imager, between a standard Helmholtz pair and the presented prototype coil are introduced.

It is able to achieve 5.8% FWHM energy resolution at 662keV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ce%3AGAGG" title="Ce:GAGG">Ce:GAGG</a>, <a href="https://publications.waset.org/abstracts/search?q=gamma-ray" title=" gamma-ray"> gamma-ray</a>, <a href="https://publications.waset.org/abstracts/search?q=radio%20frequency" title=" radio frequency"> radio frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon%20photomultiplier" title=" silicon photomultiplier"> silicon photomultiplier</a> </p> <a href="https://publications.waset.org/abstracts/66154/design-of-a-remote-radiation-sensing-module-based-on-portable-gamma-spectrometer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66154.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">332</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">593</span> Critical Approach to Define the Architectural Structure of a Health Prototype in a Rural Area of Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Domenico%20Chizzoniti">Domenico Chizzoniti</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Moscatelli"> Monica Moscatelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Letizia%20Cattani"> Letizia Cattani</a>, <a href="https://publications.waset.org/abstracts/search?q=Luca%20Preis"> Luca Preis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A primary healthcare facility in developing countries should be a multifunctional space able to respond to different requirements: Flexibility, modularity, aggregation and reversibility. These basic features could be better satisfied if applied to an architectural artifact that complies with the typological, figurative and constructive aspects of the context in which it is located. Therefore, the purpose of this paper is to identify a procedure that can define the figurative aspects of the architectural structure of the health prototype for the marginal areas of developing countries through a critical approach. The application context is the rural areas of the Northeast of Bahia in Brazil. The prototype should be located in the rural district of Quingoma, in the municipality of Lauro de Freitas, a particular place where there is still a cultural fusion of black and indigenous populations. Based on the historical analysis of settlement strategies and architectural structures in spaces of public interest or collective use, this paper aims to provide a procedure able to identify the categories and rules underlying typological and figurative aspects, in order to detect significant and generalizable elements, as well as materials and constructive techniques typically adopted in the rural areas of Brazil. The object of this work is therefore not only the recovery of certain constructive approaches but also the development of a procedure that integrates the requirements of the primary healthcare prototype with its surrounding economic, social, cultural, settlement and figurative conditions. <p class="card-text"><strong>Keywords:</strong> <a
