The model has been instrumental in identifying some of the common errors in the construction process through the spatial arrangement. The continuous use of the BIM model in the construction industry has resulted in various radical changes such as virtual prototyping. Construction virtual prototyping is a highly advanced technology that incorporates a BIM model with realistic graphical simulations, and facilitates the simulation of the project before a product is built in the factory. The paper presents virtual prototyping in the construction industry by examining its application, challenges and benefits to a construction project. Methodology approach: A case study was conducted for this study in four major construction projects, which incorporate virtual construction prototyping in several stages of the construction project. Furthermore, there was the administration of interviews with the project manager and engineer and the planning manager. Findings: Data collected from the methodological approach shows a positive response for virtual construction prototyping in construction, especially concerning communication and visualization. Furthermore, the use of virtual prototyping has increased collaboration and efficiency between construction experts handling a project. During the planning stage, virtual prototyping has increased accuracy, reduced planning time, and reduced the amount of rework during the implementation stage. Irrespective of virtual prototyping being a new concept in the construction industry, the findings outline that the approach will benefit the management of construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20operations" title="construction operations">construction operations</a>, <a href="https://publications.waset.org/abstracts/search?q=construction%20planning" title=" construction planning"> construction planning</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20simulation" title=" process simulation"> process simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20prototyping" title=" virtual prototyping"> virtual prototyping</a> </p> <a href="https://publications.waset.org/abstracts/143753/bim-model-and-virtual-prototyping-in-construction-management" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143753.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">231</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> Application of Rapid Prototyping to Create Additive Prototype Using Computer System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meftah%20O.%20Bashir">Meftah O.

The rapid prototyping process greatly reduces the time and cost necessary to bring a new product to market. The prototypes made by these systems are used in a range of industrial application including design evaluation, verification, testing, and as patterns for casting processes. These processes employ a variety of materials and mechanisms to build up the layers to build the part. The present work was to build a FDM prototyping machine that could control the X-Y motion and material deposition, to generate two-dimensional and three-dimensional complex shapes. This study focused on the deposition of wax material. This work was to find out the properties of the wax materials used in this work in order to enable better control of the FDM process. This study will look at the integration of a computer controlled electro-mechanical system with the traditional FDM additive prototyping process. The characteristics of the wax were also analysed in order to optimize the model production process. These included wax phase change temperature, wax viscosity and wax droplet shape during processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title="rapid prototyping">rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=wax" title=" wax"> wax</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20processes" title=" manufacturing processes"> manufacturing processes</a>, <a href="https://publications.waset.org/abstracts/search?q=shape" title=" shape "> shape </a> </p> <a href="https://publications.waset.org/abstracts/25158/application-of-rapid-prototyping-to-create-additive-prototype-using-computer-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25158.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">464</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> Preliminary Conceptions of 3D Prototyping Model to Experimental Investigation in Hypersonic Shock Tunnels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thiago%20Victor%20Cordeiro%20Marcos">Thiago Victor Cordeiro Marcos</a>, <a href="https://publications.waset.org/abstracts/search?q=Joao%20Felipe%20de%20Araujo%20Martos"> Joao Felipe de Araujo Martos</a>, <a href="https://publications.waset.org/abstracts/search?q=Ronaldo%20de%20Lima%20Cardoso"> Ronaldo de Lima Cardoso</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Romanelli%20Pinto"> David Romanelli Pinto</a>, <a href="https://publications.waset.org/abstracts/search?q=Paulo%20Gilberto%20de%20Paula%20Toro"> Paulo Gilberto de Paula Toro</a>, <a href="https://publications.waset.org/abstracts/search?q=Israel%20da%20Silveira%20Rego"> Israel da Silveira Rego</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonio%20Carlos%20de%20Oliveira"> Antonio Carlos de Oliveira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Currently, the use of 3D rapid prototyping, also known as 3D printing, has been investigated by some universities around the world as an innovative technique, fast, flexible and cheap for a direct plastic models manufacturing that are lighter and with complex geometries to be tested for hypersonic shock tunnel. Initially, the purpose is integrated prototyped parts with metal models that actually are manufactured through of the conventional machining and hereafter replace them with completely prototyped models. The mechanical design models to be tested in hypersonic shock tunnel are based on conventional manufacturing processes, therefore are limited forms and standard geometries. The use of 3D rapid prototyping offers a range of options that enables geometries innovation and ways to be used for the design new models. The conception and project of a prototyped model for hypersonic shock tunnel should be rethought and adapted when comparing the conventional manufacturing processes, in order to fully exploit the creativity and flexibility that are allowed by the 3D prototyping process. The objective of this paper is to compare the conception and project of a 3D rapid prototyping model and a conventional machining model, while showing the advantages and disadvantages of each process and the benefits that 3D prototyping can bring to the manufacture of models to be tested in hypersonic shock tunnel. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20prototyping" title=" 3D prototyping"> 3D prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20research" title=" experimental research"> experimental research</a>, <a href="https://publications.waset.org/abstracts/search?q=hypersonic%20shock%20tunnel" title=" hypersonic shock tunnel"> hypersonic shock tunnel</a> </p> <a href="https://publications.waset.org/abstracts/59503/preliminary-conceptions-of-3d-prototyping-model-to-experimental-investigation-in-hypersonic-shock-tunnels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59503.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">469</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> Investigate the Effects of Geometrical Structure and Layer Orientation on Strength of 3D-FDM Rapid Prototyped Samples</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.D.%20Sarhan">Ahmed A.D.

The samples will be fabricated by a FDM rapid prototyping machine in different layer orientations with variations in internal geometrical structure. The 0° orientation where layers were deposited along the length of the samples displayed superior strength and impact resistance over all the other orientations.

Instead, imagine a fashion designer in the future who produces that initial fashion drawing in a three-dimensional space and won’t leave that environment until the product is done, communicating his/her ideas with the entire development team in true to life 3D. Three-dimensional (3D) technology - while well established in many other industrial sectors like automotive, aerospace, architecture and industrial design, has only just started to open up a whole range of new opportunities for apparel designers. The paper will discuss the process of 3D simulation technology enhanced by high quality visualization of data and its capability to ensure a massive competitiveness in the market. Secondly, it will underline the most frequent problems & challenges that occur in the process chain when various partners in the production of textiles and apparel are working together. Finally, it will offer a perspective of how the Virtual Prototyping Technology will make the global textile and apparel industry change to a level where designs will be visualized on a computer and various scenarios modeled without even having to produce a physical prototype. This state-of-the-art 3D technology has been described as transformative and“disruptive”comparing to the process of the way apparel companies develop their fashion products today. It provides the benefit of virtual sampling not only for quick testing of design ideas, but also reducing process steps and having more visibility.A so called“digital asset” that can be used for other purposes such as merchandising or marketing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20visualization" title="3D visualization">3D visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=apparel" title=" apparel"> apparel</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20prototyping" title=" virtual prototyping"> virtual prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=prototyping%20technology" title=" prototyping technology"> prototyping technology</a> </p> <a href="https://publications.waset.org/abstracts/25714/can-3d-virtual-prototyping-conquers-the-apparel-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25714.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">591</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">97</span> Virtual Prototyping of LED Chip Scale Packaging Using Computational Fluid Dynamic and Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20C.%20Law">R.

It will continue to stay bright in future. As such, there is tremendous pressure to stay competitive in the market by optimizing products to next level of performance and reliability with the shortest time to market. This changes the conventional way of product design and development to virtual prototyping by means of Computer Aided Engineering (CAE). It comprises of the deployment of Finite Element Method (FEM) and Computational Fluid Dynamic (CFD). FEM accelerates the investigation for early detection of failures such as crack, improve the thermal performance of system and enhance solder joint reliability. CFD helps to simulate the flow pattern of molding material as a function of different temperature, molding parameters settings to evaluate failures like voids and displacement. This paper will briefly discuss the procedures and applications of FEM in thermal stress, solder joint reliability and CFD of compression molding in LED CSP. Integration of virtual prototyping in product development had greatly reduced the time to market. Many successful achievements with minimized number of evaluation iterations required in the scope of material, process setting, and package architecture variant have been materialized with this approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LED" title="LED">LED</a>, <a href="https://publications.waset.org/abstracts/search?q=chip%20scale%20packaging%20%28CSP%29" title=" chip scale packaging (CSP)"> chip scale packaging (CSP)</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamic%20%28CFD%29" title=" computational fluid dynamic (CFD)"> computational fluid dynamic (CFD)</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20prototyping" title=" virtual prototyping "> virtual prototyping </a> </p> <a href="https://publications.waset.org/abstracts/74429/virtual-prototyping-of-led-chip-scale-packaging-using-computational-fluid-dynamic-and-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74429.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">287</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">96</span> Influence of Drying Method in Parts of Alumina Obtained for Rapid Prototyping and Uniaxial Dry Pressing </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20O.%20Muniz">N.

Many in vitro and in vivo studies have revealed the significance of the porous structure of the biomaterials on the promotion of bone ingrowth. The use of Rapid Prototyping in the manufacture of ceramics in the biomedical area has increased in recent years and few studies are conducted on obtaining alumina pieces. The aim of this work was the study of alumina pieces obtained by 3D printing and uniaxial dry pressing (DP) in order to evaluate porosity achieved by this two different techniques. Also, the influence of the powder drying process was determined. The row alumina powders were drying by freeze drying and oven. Apparent porosity, apparent density, retraction after thermal treatment were evaluated. The porosity values obtained by DP, regardless of method of drying powders, were much lower than those obtained by RP as expected. And for the prototyped samples, the method of powder drying significantly influenced porosities, reached 48% for drying oven versus 65% for freeze-drying. Therefore, the method of 3D printing, using different powder drying, allows a better control over the porosity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title="rapid prototyping">rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=freeze-drying" title=" freeze-drying"> freeze-drying</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a>, <a href="https://publications.waset.org/abstracts/search?q=alumina" title=" alumina"> alumina</a> </p> <a href="https://publications.waset.org/abstracts/17560/influence-of-drying-method-in-parts-of-alumina-obtained-for-rapid-prototyping-and-uniaxial-dry-pressing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17560.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">471</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> Prototyping the Problem Oriented Medical Record for Connected Health Based on TypeGraphQL</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabah%20Mohammed">Sabah Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinan%20Fiaidhi"> Jinan Fiaidhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Darien%20Sawyer"> Darien Sawyer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Data integration of health through connected services can save lives in the event of a medical emergency or provide efficient and effective interventions for the benefit of the patients through the integration of bedside and bench side clinical research. Such integration will support all wind of change in healthcare by being predictive, pre-emptive, personalized, problem-oriented and participatory. Prototyping a healthcare system that enables data integration has been a big challenge for healthcare for a long time. However, an innovative solution started to emerge by focusing on problem lists where everything can connect the problem list forming a growing graph. This notion was introduced by Dr. Lawrence Weed in early 70’s, but the enabling technologies weren’t mature enough to provide a successful implementation prototype. In this article, we are describing our efforts in prototyping Dr. Lawrence Weed's problem-oriented medical record (POMR) and his patient case schema (SOAP) to shape a prototype for connected health. For this, we are using the TypeGraphQL API and our enterprise-based QL4POMR to describe a Web-Based gateway for healthcare services connectivity. Our prototype has reported success in connecting to the HL7 FHIR medical record and the OpenTarget biomedical repositories. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=connected%20health" title="connected health">connected health</a>, <a href="https://publications.waset.org/abstracts/search?q=problem-oriented%20healthcare%20record" title=" problem-oriented healthcare record"> problem-oriented healthcare record</a>, <a href="https://publications.waset.org/abstracts/search?q=SOAP" title=" SOAP"> SOAP</a>, <a href="https://publications.waset.org/abstracts/search?q=QL4POMR" title=" QL4POMR"> QL4POMR</a>, <a href="https://publications.waset.org/abstracts/search?q=typegraphQL" title=" typegraphQL"> typegraphQL</a> </p> <a href="https://publications.waset.org/abstracts/155525/prototyping-the-problem-oriented-medical-record-for-connected-health-based-on-typegraphql" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155525.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">97</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> PLA Plastic as Biodegradable Material for 3D Printers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juraj%20Beniak">Juraj Beniak</a>, <a href="https://publications.waset.org/abstracts/search?q=%C4%BDubom%C3%ADr%20%C5%A0oo%C5%A1"> Ľubomír Šooš</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Kri%C5%BEan"> Peter Križan</a>, <a href="https://publications.waset.org/abstracts/search?q=Milo%C5%A1%20Mat%C3%BA%C5%A1"> Miloš Matúš</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Within Rapid Prototyping technologies are used many types of materials. Many of them are recyclable but there are still as plastic like, so practically they do not degrade in the landfill. Polylactic acid (PLA) is one of the special plastic materials which are biodegradable and also available for 3D printing within Fused Deposition Modelling (FDM) technology. The question is, if the mechanical properties of produced models are comparable to similar technical plastic materials which are usual for prototype production. Presented paper shows the experiments results for tensile strength measurements for specimens prepared with different 3D printer settings and model orientation. Paper contains also the comparison of tensile strength values with values measured on specimens produced by conventional technologies as injection moulding. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3D%20printing" title="3D printing">3D printing</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20plastic" title=" biodegradable plastic"> biodegradable plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=fused%20deposition%20modeling" title=" fused deposition modeling"> fused deposition modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=PLA%20plastic" title=" PLA plastic"> PLA plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title=" rapid prototyping"> rapid prototyping</a> </p> <a href="https://publications.waset.org/abstracts/37301/pla-plastic-as-biodegradable-material-for-3d-printers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37301.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">416</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> Fast Prototyping of Precise, Flexible, Multiplexed, Printed Electrochemical Enzyme-Linked Immunosorbent Assay System for Point-of-Care Biomarker Quantification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahrasadat%20Hosseini">Zahrasadat Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Yuan"> Jie Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Point-of-care (POC) diagnostic devices based on lab-on-a-chip (LOC) technology have the potential to revolutionize medical diagnostics.

The technique efficiently assesses and analyses the mechanical and thermal capabilities of fresh fruit packing boxes prior to making production investments. Comprehensive structural, aerodynamic, and thermodynamic data from designs were collected and evaluated in comparison to real-world packaging needs. Physical prototypes of potential designs were created and evaluated afterward. The virtual prototype is created with computer-aided graphics, computational structural dynamics, and computational fluid dynamics technologies. The virtual prototyping quickly generated data on carton compression strength, airflow resistance, produce cooling rate, spatiotemporal temperature, and product quality map in the cold chain within a few hours. Six distinct designs were analysed. All the various carton designs showed similar effectiveness in preserving the quality of the goods. The innovative packaging box design is more compact, resulting in a higher freight density of 1720 kg more fruit per reefer compared to the commercial counterpart. The precooling process was improved, resulting in a 17% increase in throughput and a 30% reduction in power usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=postharvest" title="postharvest">postharvest</a>, <a href="https://publications.waset.org/abstracts/search?q=container%20logistics" title=" container logistics"> container logistics</a>, <a href="https://publications.waset.org/abstracts/search?q=space%2Fvolume%20usage" title=" space/volume usage"> space/volume usage</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20method" title=" computational method"> computational method</a>, <a href="https://publications.waset.org/abstracts/search?q=packaging%20technology" title=" packaging technology"> packaging technology</a> </p> <a href="https://publications.waset.org/abstracts/183359/virtual-prototyping-of-ventilated-corrugated-fibreboard-carton-of-fresh-fruit-for-improved-containerized-transportation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183359.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">59</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">90</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">89</span> Investigating the Viability of Small-Scale Rapid Alloy Prototyping of Interstitial Free Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Talal%20S.%20Abdullah">Talal S.

Lavery</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The defining property of Interstitial Free (IF) steels is formability, comprehensively measured using the Lankford coefficient (r-value) on uniaxial tensile test data. The contributing factors supporting this feature are grain size, orientation, and elemental additions. The processes that effectively modulate these factors are the casting procedure, hot rolling, and heat treatment. An existing methodology is well-practised in the steel Industry; however, large-scale production and experimentation consume significant proportions of time, money, and material. Introducing small-scale rapid alloy prototyping (RAP) as an alternative process would considerably reduce the drawbacks relative to standard practices. The aim is to finetune the existing fundamental procedures implemented in the industrial plant to adapt to the RAP route. IF material is remelted in the 80-gram coil induction melting (CIM) glovebox. To birth small grains, maximum deformation must be induced onto the cast material during the hot rolling process. The rolled strip must then satisfy the polycrystalline behaviour of the bulk material by displaying a resemblance in microstructure, hardness, and formability to that of the literature and actual plant steel. A successful outcome of this work is that small-scale RAP can achieve target compositions with similar microstructures and statistically consistent mechanical properties which complements and accelerates the development of novel steel grades. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20alloy%20prototyping" title="rapid alloy prototyping">rapid alloy prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20anisotropy" title=" plastic anisotropy"> plastic anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=interstitial%20free" title=" interstitial free"> interstitial free</a>, <a href="https://publications.waset.org/abstracts/search?q=miniaturised%20tensile%20testing" title=" miniaturised tensile testing"> miniaturised tensile testing</a>, <a href="https://publications.waset.org/abstracts/search?q=formability" title=" formability"> formability</a> </p> <a href="https://publications.waset.org/abstracts/158343/investigating-the-viability-of-small-scale-rapid-alloy-prototyping-of-interstitial-free-steels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158343.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">114</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">88</span> Portable Hands-Free Process Assistant for Gas Turbine Maintenance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elisabeth%20Brandenburg">Elisabeth Brandenburg</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Woll"> Robert Woll</a>, <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Stark"> Rainer Stark</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents how smart glasses and voice commands can be used for improving the maintenance process of industrial gas turbines.

The convergence of mobile technology is driving new business opportunities, innovations in healthcare service delivery and the promise of a better life tomorrow for different populations with various healthcare needs. One of the most important phases for the combination of health care and mobile applications is to elicit requirements correctly. In this paper, four articles from different research directions with four topics on healthcare were detailed analyzed and summarized. We identified the underlying problems in guidance to develop mobile applications to provide healthcare service for Older adults, Women in menopause, Patients undergoing covid. These case studies cover several elicitation methods: survey, prototyping, focus group interview and questionnaire. And the effectiveness of these methods was analyzed along with the advantages and limitations of these methods, which is beneficial to adapt the elicitation methods for future software development process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=healthcare" title="healthcare">healthcare</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20requirement%20elicitation" title=" software requirement elicitation"> software requirement elicitation</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20applications" title=" mobile applications"> mobile applications</a>, <a href="https://publications.waset.org/abstracts/search?q=prototyping" title=" prototyping"> prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=focus%20group%20interview" title=" focus group interview"> focus group interview</a> </p> <a href="https://publications.waset.org/abstracts/155466/methods-used-to-perform-requirements-elicitation-for-healthcare-software-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155466.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">148</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">86</span> Expert Review on Conceptual Design Model of Assistive Courseware for Low Vision (AC4LV) Learners</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurulnadwan%20Aziz">Nurulnadwan Aziz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ariffin%20Abdul%20Mutalib"> Ariffin Abdul Mutalib</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Mahfuzah%20Sarif"> Siti Mahfuzah Sarif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper reports an ongoing project regarding the development of Conceptual Design Model of Assistive Courseware for Low Vision (AC4LV) learners.

However, integrating AI with cloud computing poses challenges as these fields are often disjointed, and many advancements remain difficult to access, obscured in complex documentation or scattered across research reports. For this reason, we share experiences from prototype projects combining these technologies.

A key challenge associated with this technology is that RP parts often feature undesirable levels of surface roughness for certain applications. To combat this phenomenon, an experimental technique called Design of Experiments (DOE) can be employed during the growth procedure to statistically analyze which RP growth parameters are most influential to part surface roughness. Utilizing DOE to identify such factors is important because it is a technique that can be used to optimize a manufacturing process, which saves time, money, and increases product quality. In this study, a four-factor/two level DOE experiment was performed to investigate the effect of temperature, layer thickness, infill percentage, and infill speed on the surface roughness of RP prototypes. Samples were grown using the sixteen different possible growth combinations associated with a four-factor/two level study, and then the surface roughness data was gathered for each set of factors. After applying DOE statistical analysis to these data, it was determined that layer thickness played the most significant role in the prototype surface roughness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title="rapid prototyping">rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiments" title=" design of experiments"> design of experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=factors%20and%20levels" title=" factors and levels"> factors and levels</a> </p> <a href="https://publications.waset.org/abstracts/45741/effects-of-process-parameter-variation-on-the-surface-roughness-of-rapid-prototyped-samples-using-design-of-experiments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45741.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">262</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">83</span> A Comparative Study on the Dimensional Error of 3D CAD Model and SLS RP Model for Reconstruction of Cranial Defect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Siva%20Rama%20Krishna">L.

There are several RP process like Stereolithography (SLA), Solid Ground Curing (SGC), Selective Laser Sintering (SLS), Fused Deposition Modelling (FDM), 3D Printing (3DP) among them SLS and FDM RP processes are used to fabricate pattern of custom cranial implant. RP technology is useful in engineering and biomedical application. This is helpful in engineering for product design, tooling and manufacture etc. RP biomedical applications are design and development of medical devices, instruments, prosthetics and implantation; it is also helpful in planning complex surgical operation. The traditional approach limits the full appreciation of various bony structure movements and therefore the custom implants produced are difficult to measure the anatomy of parts and analyse the changes in facial appearances accurately. Cranioplasty surgery is a surgical correction of a defect in cranial bone by implanting a metal or plastic replacement to restore the missing part. This paper aims to do a comparative study on the dimensional error of CAD and SLS RP Models for reconstruction of cranial defect by comparing the virtual CAD with the physical RP model of a cranial defect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title="rapid prototyping">rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20sintering" title=" selective laser sintering"> selective laser sintering</a>, <a href="https://publications.waset.org/abstracts/search?q=cranial%20defect" title=" cranial defect"> cranial defect</a>, <a href="https://publications.waset.org/abstracts/search?q=dimensional%20error" title=" dimensional error"> dimensional error</a> </p> <a href="https://publications.waset.org/abstracts/3068/a-comparative-study-on-the-dimensional-error-of-3d-cad-model-and-sls-rp-model-for-reconstruction-of-cranial-defect" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3068.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">82</span> Effect of Varying Scaffold Architecture and Porosity of Calcium Alkali Orthophosphate Based-Scaffolds for Bone Tissue Engineering </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20Adel">D.

First, the mechanical and physical properties of the scaffolds (porosity, compressive strength, and solubility) was assessed and second their potential to facilitate homogenous colonization with osteogenic cells and extracellular bone matrix formation throughout the porous scaffold architecture. To this end murine and rat calavarie osteoblastic cells were dynamically seeded on both scaffold types under perfusion with concentrations of 3 million cells. The amount of cells and extracellular matrix as well as osteogenic marker expression was evaluated using hard tissue histology, immunohistochemistry, and histomorphometric analysis. Total porosities of both scaffolds were 86.9 % and 50% for SSM and RP respectively, Compressive strength values were 0.46 ± 0.2 MPa for SSM and 6.6± 0.8 MPa for RP. Regarding the cellular behavior, RP scaffolds displayed a higher cell and matrix percentage of 24.45%. Immunoscoring yielded strong osteocalcin expression of cells and matrix in RP scaffolds and a moderate expression in SSM scaffolds. 3D printed RP scaffolds displayed superior mechanical and biological properties compared to SSM. 3D printed scaffolds represent excellent candidates for bone tissue engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calcium%20alkali%20orthophosphate" title="calcium alkali orthophosphate">calcium alkali orthophosphate</a>, <a href="https://publications.waset.org/abstracts/search?q=extracellular%20matrix%20mineralization" title=" extracellular matrix mineralization"> extracellular matrix mineralization</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoblast%20differentiation" title=" osteoblast differentiation"> osteoblast differentiation</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title=" rapid prototyping"> rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffold" title=" scaffold"> scaffold</a> </p> <a href="https://publications.waset.org/abstracts/46386/effect-of-varying-scaffold-architecture-and-porosity-of-calcium-alkali-orthophosphate-based-scaffolds-for-bone-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46386.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">81</span> Influence of Internal Topologies on Components Produced by Selective Laser Melting: Numerical Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Mal%C3%A7a">C.

Aspects such as reducing the weight of components, associated with the low volume of material required and the almost non-existent material waste, speed and flexibility of production and, primarily, a high mechanical strength combined with high structural performance, are competitive advantages in any industrial sector, from automotive, molds, aviation, aerospace, construction, pharmaceuticals, medicine and more recently in human tissue engineering. Such features, properties and functionalities are attained in metal components produced using the additive technique of Rapid Prototyping from metal powders commonly known as Selective Laser Melting (SLM), with optimized internal topologies and varying densities. In order to produce components with high strength and high structural and functional performance, regardless of the type of application, three different internal topologies were developed and analyzed using numerical computational tools. The developed topologies were numerically submitted to mechanical compression and four point bending testing. Finite Element Analysis results demonstrate how different internal topologies can contribute to improve mechanical properties, even with a high degree of porosity relatively to fully dense components. Results are very promising not only from the point of view of mechanical resistance, but especially through the achievement of considerable variation in density without loss of structural and functional high performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20topologies" title=" internal topologies"> internal topologies</a>, <a href="https://publications.waset.org/abstracts/search?q=porosity" title=" porosity"> porosity</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title=" rapid prototyping"> rapid prototyping</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a> </p> <a href="https://publications.waset.org/abstracts/17892/influence-of-internal-topologies-on-components-produced-by-selective-laser-melting-numerical-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">80</span> Integration of Big Data to Predict Transportation for Smart Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun-Young%20Jang">Sun-Young Jang</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Ah%20Kim"> Sung-Ah Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongyoun%20Shin"> Dongyoun Shin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Intelligent transportation system is essential to build smarter cities. Machine learning based transportation prediction could be highly promising approach by delivering invisible aspect visible. In this context, this research aims to make a prototype model that predicts transportation network by using big data and machine learning technology. In detail, among urban transportation systems this research chooses bus system.  The research problem that existing headway model cannot response dynamic transportation conditions. Thus, bus delay problem is often occurred. To overcome this problem, a prediction model is presented to fine patterns of bus delay by using a machine learning implementing the following data sets; traffics, weathers, and bus statues. This research presents a flexible headway model to predict bus delay and analyze the result. The prototyping model is composed by real-time data of buses. The data are gathered through public data portals and real time Application Program Interface (API) by the government. These data are fundamental resources to organize interval pattern models of bus operations as traffic environment factors (road speeds, station conditions, weathers, and bus information of operating in real-time). The prototyping model is designed by the machine learning tool (RapidMiner Studio) and conducted tests for bus delays prediction. This research presents experiments to increase prediction accuracy for bus headway by analyzing the urban big data. The big data analysis is important to predict the future and to find correlations by processing huge amount of data. Therefore, based on the analysis method, this research represents an effective use of the machine learning and urban big data to understand urban dynamics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20city" title=" smart city"> smart city</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20cost" title=" social cost"> social cost</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation%20network" title=" transportation network"> transportation network</a> </p> <a href="https://publications.waset.org/abstracts/76004/integration-of-big-data-to-predict-transportation-for-smart-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76004.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">260</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">79</span> Development of a Novel Ankle-Foot Orthotic Using a User Centered Approach for Improved Satisfaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahlad%20Neti">Ahlad Neti</a>, <a href="https://publications.waset.org/abstracts/search?q=Elisa%20Arch"> Elisa Arch</a>, <a href="https://publications.waset.org/abstracts/search?q=Martha%20Hall"> Martha Hall</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Studies have shown that individuals who use Ankle-Foot-Orthoses (AFOs) have a high level of dissatisfaction regarding their current AFOs. Studies point to the focus on technical design with little attention given to the user perspective as a source of AFO designs that leave users dissatisfied. To design a new AFO that satisfies users and thereby improves their quality of life, the reasons for their dissatisfaction and their wants and needs for an improved AFO design must be identified. There has been little research into the user perspective on AFO use and desired improvements, so the relationship between AFO design and satisfaction in daily use must be assessed to develop appropriate metrics and constraints prior to designing a novel AFO. To assess the user perspective on AFO design, structured interviews were conducted with 7 individuals (average age of 64.29±8.81 years) who use AFOs. All interviews were transcribed and coded to identify common themes using Grounded Theory Method in NVivo 12. Qualitative analysis of these results identified sources of user dissatisfaction such as heaviness, bulk, and uncomfortable material and overall needs and wants for an AFO. Beyond the user perspective, certain objective factors must be considered in the construction of metrics and constraints to ensure that the AFO fulfills its medical purpose. These more objective metrics are rooted in a common medical device market and technical standards. Given the large body of research concerning these standards, these objective metrics and constraints were derived through a literature review. Through these two methods, a comprehensive list of metrics and constraints accounting for both the user perspective on AFO design and the AFO’s medical purpose was compiled. These metrics and constraints will establish the framework for designing a new AFO that carries out its medical purpose while also improving the user experience. The metrics can be categorized into several overarching areas for AFO improvement. Categories of user perspective related metrics include comfort, discreteness, aesthetics, ease of use, and compatibility with clothing. Categories of medical purpose related metrics include biomechanical functionality, durability, and affordability. These metrics were used to guide an iterative prototyping process. Six concepts were ideated and compared using system-level analysis. From these six concepts, two concepts – the piano wire model and the segmented model – were selected to move forward into prototyping. Evaluation of non-functional prototypes of the piano wire and segmented models determined that the piano wire model better fulfilled the metrics by offering increased stability, longer durability, fewer points for failure, and a strong enough core component to allow a sock to cover over the AFO while maintaining the overall structure. As such, the piano wire AFO has moved forward into the functional prototyping phase, and healthy subject testing is being designed and recruited to conduct design validation and verification. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ankle-foot%20orthotic" title="ankle-foot orthotic">ankle-foot orthotic</a>, <a href="https://publications.waset.org/abstracts/search?q=assistive%20technology" title=" assistive technology"> assistive technology</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20centered%20design" title=" human centered design"> human centered design</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20devices" title=" medical devices"> medical devices</a> </p> <a href="https://publications.waset.org/abstracts/131581/development-of-a-novel-ankle-foot-orthotic-using-a-user-centered-approach-for-improved-satisfaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131581.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">78</span> User-Centered Design in the Development of Patient Decision Aids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ariane%20Plaisance">Ariane Plaisance</a>, <a href="https://publications.waset.org/abstracts/search?q=Holly%20O.%20Witteman"> Holly O.

Without such discussions, interventions that prolong life at the cost of decreasing its quality may be used without appropriate guidance from patients. We employed user-centered design to adapt an existing decision aid (DA) about CPR to create a novel wiki-based DA adapted to the context of a single ICU and tailored to individual patient’s risk factors. During Phase 1, we conducted three weeks of ethnography of the decision-making context in our ICU to identify clinician and patient needs for a decision aid. During this time, we observed five dyads of intensivists and patients discussing their wishes concerning life-sustaining interventions. We also conducted semi-structured interviews with the attending intensivists in this ICU. During Phase 2, we conducted three rounds of rapid prototyping involving 15 patients and 11 other allied health professionals. We recorded discussions between intensivists and patients and used a standardized observation grid to collect patients’ comments and sociodemographic data. We applied content analysis to field notes, verbatim transcripts and the completed observation grids. Each round of observations and rapid prototyping iteratively informed the design of the next prototype. We also used the programming architecture of a wiki platform to embed the GO-FAR prediction rule programming code that we linked to a risk graphics software to better illustrate outcome risks calculated. During Phase I, we identified the need to add a section in our DA concerning invasive mechanical ventilation in addition to CPR because both life-sustaining interventions were often discussed together by physicians. During Phase II, we produced a context-adapted decision aid about CPR and mechanical ventilation that includes a values clarification section, questions about the patient’s functional autonomy prior to admission to the ICU and the functional decline that they would judge acceptable upon hospital discharge, risks and benefits of CPR and invasive mechanical ventilation, population-level statistics about CPR, a synthesis section to help patients come to a final decision and an online calculator based on the GO-FAR prediction rule. Even though the three rounds of rapid prototyping led to simplifying the information in our DA, 60% (n= 3/5) of the patients involved in the last cycle still did not understand the purpose of the DA. We also identified gaps in the discussion and documentation of patients’ preferences concerning life-sustaining interventions (e.g.,. CPR, invasive mechanical ventilation). The final version of our DA and our online wiki-based GO-FAR risk calculator using the IconArray.com risk graphics software are available online at www.wikidecision.org and are ready to be adapted to other contexts. Our results inform producers of decision aids on the use of wikis and user-centered design to develop DAs that are better adapted to users’ needs. Further work is needed on the creation of a video version of our DA.

As laboratory setup contains transformer with thyristor controlled tap changer, a wider scope of setup capabilities is presented. Information about used communication interface, data maintenance, and storage solution as well as used Simulink real-time features is presented. List and description of all measurements are provided. Potential of laboratory setup modifications is evaluated. For purposes of Rapid Control Prototyping, a dedicated environment was used Simulink RealTime. Therefore, load model Functional Unit Controller is based on a PC computer with I/O cards and Simulink RealTime software. Simulink RealTime was used to create real-time applications directly from Simulink models. In the next step, applications were loaded on a target computer connected to physical devices that provided opportunity to perform Hardware in the Loop (HIL) tests, as well as the mentioned Rapid Control Prototyping process. With Simulink RealTime, Simulink models were extended with I/O cards driver blocks that made automatic generation of real-time applications and performing interactive or automated runs on a dedicated target computer equipped with a real-time kernel, multicore CPU, and I/O cards possible. Results of performed laboratory tests are presented. Different load configurations are described and experimental results are presented. This includes simulation of under frequency load shedding, frequency and voltage dependent characteristics of groups of load units, time characteristics of group of different load units in a chosen area and arbitrary active and reactive power regulation basing on defined schedule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MATLAB" title="MATLAB">MATLAB</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20converter" title=" power converter"> power converter</a>, <a href="https://publications.waset.org/abstracts/search?q=Simulink%20Real-Time" title=" Simulink Real-Time"> Simulink Real-Time</a>, <a href="https://publications.waset.org/abstracts/search?q=thyristor-controlled%20tap%20changer" title=" thyristor-controlled tap changer"> thyristor-controlled tap changer</a> </p> <a href="https://publications.waset.org/abstracts/50924/150-kva-multifunction-laboratory-test-unit-based-on-power-frequency-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50924.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">323</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">76</span> GynApp: A Mobile Application for the Organization and Control of Gynecological Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Betzabet%20Garc%C3%ADa-Mendoza">Betzabet García-Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Roc%C3%ADo%20Abascal-Mena"> Rocío Abascal-Mena</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Breast and cervical cancer are among the leading causes of death of women in Mexico. The mortality rate for these diseases is alarming, even though there have been many campaigns for making people self-aware of the importance of conducting gynecological studies for a timely prevention and detection, these have not been enough. This paper presents a mobile application for organizing and controlling gynecological studies in order to help and boost women to take care of their bodies and health.

The old techniques are time consuming and ultimately destructive to the tissues under the examination. In recent few decades, thanks to the boost of technology, non-destructive visualization techniques, such as X-ray computed tomography (CT), magnetic resonance imaging (MRI), selective plane illumination microscopy (SPIM), and optical projection tomography (OPT), have come to the forefront. Among these techniques, CT is excellent for mineralized tissues such as bone or dentine. In addition, CT it is faster than other aforementioned techniques and the sample remains intact. In this article, applications, advantages, and limitations of micro-CT is discussed, in addition to some information about micro-CT of soft tissue. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Micro-CT" title="Micro-CT">Micro-CT</a>, <a href="https://publications.waset.org/abstracts/search?q=hard%20tissue" title=" hard tissue"> hard tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=bone" title=" bone"> bone</a>, <a href="https://publications.waset.org/abstracts/search?q=attenuation%20coefficient" title=" attenuation coefficient"> attenuation coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20prototyping" title=" rapid prototyping"> rapid prototyping</a> </p> <a href="https://publications.waset.org/abstracts/128393/micro-ct-imaging-of-hard-tissues" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128393.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">142</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">73</span> Design Aspects of 3D Printing for Fashion and Textiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chi-Chung%20Marven%20Chick">Chi-Chung Marven Chick</a>, <a href="https://publications.waset.org/abstracts/search?q=Chu-Po%20Ho"> Chu-Po Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Sau-Chuen%20Joe%20Au"> Sau-Chuen Joe Au</a>, <a href="https://publications.waset.org/abstracts/search?q=Wing-Fai%20Sidney%20Wong"> Wing-Fai Sidney Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Wai%20Kan"> Chi-Wai Kan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 3D printing is now drawing attention to manufacturing process. In fashion and textile industry, many 3D printing applications had been developed for prototyping or even final product production because of its great flexibility in production. However, when compared with conventional manufacturing processes for fashion and textiles, the design aspects and requirements may not be same for using 3D printing process. Therefore, in this paper, we will compare the design aspects between conventional manufacturing processes and 3D printing processes. Also, the material requirements related to the design in 3D printing for fashion and textiles will be reviewed and discussed. This review paper may demonstrate a possible way to develop 3D printing method(s) for fashion and textiles. <p class="card-text"><strong>Keywords:</strong> <a
