The eye-tracking experiment is designed to calculate the average time ranking of the specific parts of the bionic shape that the subjects are looking at. Key bionic shape is explored through the experiment and then applied to a desk lamp bionic design. During the design case, FAHP (Fuzzy Analytic Hierachy Process) and SD (Semantic Differential) method are firstly used to identify consumer emotional perception model toward desk lamp before product design. Through investigating different desk lamp design elements and consumer views, the form design factors on the desk lamp product are reflected and all design schemes are sequenced after caculation. Desk lamp form bionic design method is combined the key bionic shape extracted from eye-tracking experiment and priority of desk lamp design schemes. This study provides an objective and rational method to product form bionic design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bionic%20design%3B%20Form%3B%20Eye%20tracking%3B%20FAHP%3B%20Desk%20lamp" title="Bionic design; Form; Eye tracking; FAHP; Desk lamp">Bionic design; Form; Eye tracking; FAHP; Desk lamp</a> </p> <a href="https://publications.waset.org/abstracts/100951/product-form-bionic-design-based-on-eye-tracking-data-a-case-study-of-desk-lamp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100951.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">226</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">14521</span> Application of Generalized Taguchi and Design of Experiment Methodology for Rebar Production at an Integrated Steel Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20B.%20V.%20S.%20P.%20Sastry">S.

NIMROD software was used to build up the matrix of experiments and to analyze the results. The software has the advantages of being easy to use and consists of a forced way, with some choices about the number and range of variation of the parameters, and the desired polynomial shape. The first design of experiments performed concern the drying with constant input characteristics of the hot air in the dryer and a second design of experiments in which the drying chamber is coupled with a solar collector. The first design of experiments allows us to study the influence of various parameters and get the studied answers in a polynomial form. The correspondence between the polynomial thus determined, and the model results were good. The results of the polynomials of the second design of experiments and those of the model are worse than the results in the case of drying with constant input conditions. This is due to the strong link between all the input parameters, especially, the surface of the sensor and the drying chamber, and the mass of the product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20drying" title="solar drying">solar drying</a>, <a href="https://publications.waset.org/abstracts/search?q=experiment%20design%20method" title=" experiment design method"> experiment design method</a>, <a href="https://publications.waset.org/abstracts/search?q=NIMROD" title=" NIMROD"> NIMROD</a>, <a href="https://publications.waset.org/abstracts/search?q=mint%20leaves" title=" mint leaves"> mint leaves</a> </p> <a href="https://publications.waset.org/abstracts/20272/dimensioning-of-a-solar-dryer-with-application-of-an-experiment-design-method-for-drying-food-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20272.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">503</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">14519</span> Parametric Screening and Design Refinement of Ceiling Fan Blades</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shamraiz%20Ahmad">Shamraiz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Riaz%20Ahmad"> Riaz Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Maqsood"> Adnan Maqsood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper describes the application of 2k-design of experiment in order to screen the geometric parameters and experimental refinement of ceiling fan blades. The ratio of the air delivery to the power consumed is commonly known as service value (SV) in ceiling fan designer’s community. Service value was considered as the response for 56 inch ceiling fan and four geometric parameters (bend position at root, bend position at tip, bent angle at root and bent angle at tip) of blade were analyzed. With two levels, the 4-design parameters along with their eleven interactions were studied and design of experiment was employed for experimental arrangement. Blade manufacturing and testing were done in a medium scale enterprise. The objective was achieved and service value of ceiling fan was increased by 10.4 % without increasing the cost of production and manufacturing system. Experiments were designed and results were analyzed using Minitab® 16 software package. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parametric%20screening" title="parametric screening">parametric screening</a>, <a href="https://publications.waset.org/abstracts/search?q=2k-design%20of%20experiment" title=" 2k-design of experiment"> 2k-design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=ceiling%20fan" title=" ceiling fan"> ceiling fan</a>, <a href="https://publications.waset.org/abstracts/search?q=service%20value" title=" service value"> service value</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20improvement" title=" performance improvement "> performance improvement </a> </p> <a href="https://publications.waset.org/abstracts/11017/parametric-screening-and-design-refinement-of-ceiling-fan-blades" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11017.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">564</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">14518</span> Early Phase Design Study of a Sliding Door with Multibody Simulations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erkan%20Talay">Erkan Talay</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Yigit%20Yagci"> Mustafa Yigit Yagci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the systems like sliding door, designers should predict not only strength but also dynamic behavior of the system and this prediction usually becomes more critical if design has radical changes refer to previous designs. Also, sometimes physical tests could cost more than expected, especially for rail geometry changes, since this geometry affects design of the body. The aim of the study is to observe and understand the dynamics of the sliding door in virtual environment. For this, multibody dynamic model of the sliding door was built and then affects of various parameters like rail geometry, roller diameters, or center of mass detected.

This study takes Taipei Station as the research base and aims to apply the use of Internet of things (IoT) application for underground evacuation mobility design. The first experiment identified passengers' evacuation behaviors and spatial cognition in underground spaces by wayfinding tasks and thinking aloud, then defined the design conditions of User Interface (UI) and proposed the UI design.  The second experiment evaluated the UI design based on passengers' evacuation behaviors by wayfinding tasks and think aloud again as same as the first experiment. The first experiment found that the design conditions that the subjects were most concerned about were "map" and hoping to learn the relative position of themselves with other landmarks by the map and watch the overall route. "Position" needs to be accurately labeled to determine the location in underground space. Each step of the escape instructions should be presented clearly in "navigation bar." The "message bar" should be informed of the next or final target exit. In the second experiment with the UI design, we found that the "spatial map" distinguishing between walking and non-walking areas with shades of color is useful. The addition of 2.5D maps of the UI design increased the user's perception of space. Amending the color of the corner diagram in the "escape route" also reduces the confusion between the symbol and other diagrams. The larger volume of toilets and elevators can be a judgment of users' relative location in "Hardware facilities." Fire extinguisher icon should be highlighted. "Fire point tips" of the UI design indicated fire with a graphical fireball can convey precise information to the escaped person. "Fire point tips" of the UI design indicated fire with a graphical fireball can convey precise information to the escaped person. However, "Compass and return to present location" are less used in underground space. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evacuation%20behaviors" title="evacuation behaviors">evacuation behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=IoT%20application" title=" IoT application"> IoT application</a>, <a href="https://publications.waset.org/abstracts/search?q=map%20UI%20design" title=" map UI design"> map UI design</a>, <a href="https://publications.waset.org/abstracts/search?q=underground%20station" title=" underground station"> underground station</a> </p> <a href="https://publications.waset.org/abstracts/98069/map-ui-design-of-iot-application-based-on-passenger-evacuation-behaviors-in-underground-station" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98069.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">207</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">14514</span> Optimal Design of Submersible Permanent Magnet Linear Synchronous Motor Based Design of Experiment and Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Zhang">Xiao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wensheng%20Xiao"> Wensheng Xiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Junguo%20Cui"> Junguo Cui</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongmin%20Wang"> Hongmin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Submersible permanent magnet linear synchronous motors (SPMLSMs) are electromagnetic devices, which can directly drive plunger pump to obtain the crude oil. Those motors have been gradually applied in oil fields due to high thrust force density and high efficiency. Since the force performance closely depends on the concrete structural parameters, the seven different structural parameters are investigated in detail. This paper presents an optimum design of an SPMLSM to minimize the detent force and maximize the thrust by using design of experiment (DOE) and genetic algorithm (GA). The three significant structural parameters (air-gap length, slot width, pole-arc coefficient) are separately screened using 27 1/16 fractional factorial design (FFD) to investigate the significant effect of seven parameters used in this research on the force performance. Response surface methodology (RSM) is well adapted to make analytical model of thrust and detent force with constraints of corresponding significant parameters and enable objective function to be easily created, respectively. GA is performed as a searching tool to search for the Pareto-optimal solutions. By finite element analysis, the proposed PMLSM shows merits in improving thrust and reducing the detent force dramatically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20performance" title=" force performance"> force performance</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment%20%28DOE%29" title=" design of experiment (DOE)"> design of experiment (DOE)</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm%20%28GA%29" title=" genetic algorithm (GA)"> genetic algorithm (GA)</a> </p> <a href="https://publications.waset.org/abstracts/72951/optimal-design-of-submersible-permanent-magnet-linear-synchronous-motor-based-design-of-experiment-and-genetic-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72951.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">290</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">14513</span> The Engineering Design of the Temple of Dendera in the City of Qena, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shady%20Ahmed%20Emara">Shady Ahmed Emara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introductory statement: The temple is characterized by a unique engineering design. This study aimed to explain the means that were used to reach this design. Background of the Study: Temple of Dandara consists of 24 columns with a height of 18m and a diameter of 2m. This paper is about the engineering method for constructing these huge columns. Two experiments were conducted at the temple. The first experiment used AutoCAD to compare the similarity of the columns in terms of dimensions. The second experiment used a laser rangefinder to measure the extent of the match between the heights between the columns. The Major Findings of the Study: (1) The method of constructing the columns was through several divided layers. It is divided into two halves and built opposite each other to maintain the integrity of the columns. (2) The match between the heights of the columns, which reached the error rate between one column and another, is only 1 mm. Concluding Statement: Both experiences will be explained through 2D and 3D. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ancient" title="ancient">ancient</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture" title=" architecture"> architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=building" title=" building"> building</a> </p> <a href="https://publications.waset.org/abstracts/155684/the-engineering-design-of-the-temple-of-dendera-in-the-city-of-qena-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155684.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">103</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">14512</span> Enhancement in Digester Efficiency and Numerical Analysis for Optimal Design Parameters of Biogas Plant Using Design of Experiment Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajneesh">Rajneesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Singh"> Priyanka Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomass resources have been one of the main energy sources for mankind since the dawn of civilization. There is a vast scope to convert these energy sources into biogas which is a clean, low carbon technology for efficient management and conversion of fermentable organic wastes into a cheap and versatile fuel and bio/organic manure. Thus, in order to enhance the performance of anaerobic digester, an optimizing analysis of resultant parameters (organic dry matter (oDM) content, methane percentage, and biogas yield) has been done for a plug flow anaerobic digester having mesophilic conditions (20-40°C) with the wet fermentation process. Based on the analysis, correlations for oDM, methane percentage, and biogas yield are derived using multiple regression analysis. A statistical model is developed to correlate the operating variables using the design of experiment approach by selecting central composite design (CCD) of a response surface methodology. Results shown in the paper indicates that as the operating temperature increases the efficiency of digester gets improved provided that the pH and hydraulic retention time (HRT) remains constant. Working in an optimized range of carbon-nitrogen ratio for the plug flow digester, the output parameters show a positive change with the variation of dry matter content (DM). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biogas" title="biogas">biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=digester%20efficiency" title=" digester efficiency"> digester efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=plug%20flow%20digester" title=" plug flow digester"> plug flow digester</a> </p> <a href="https://publications.waset.org/abstracts/46205/enhancement-in-digester-efficiency-and-numerical-analysis-for-optimal-design-parameters-of-biogas-plant-using-design-of-experiment-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46205.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">14511</span> Experimental Analysis of the Plate-on-Tube Evaporator on a Domestic Refrigerator’s Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mert%20Tosun">Mert Tosun</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%C4%9Fba%20Tosun"> Tuğba Tosun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evaporator is the utmost important component in the refrigeration system, since it enables the refrigerant to draw heat from the desired environment, i.e. the refrigerated space. Studies are being conducted on this component which generally affects the performance of the system, where energy efficient products are important. This study was designed to enhance the effectiveness of the evaporator in the refrigeration cycle of a domestic refrigerator by adjusting the capillary tube length, refrigerant amount, and the evaporator pipe diameter to reduce energy consumption. The experiments were conducted under identical thermal and ambient conditions. Experiment data were analysed using the Design of Experiment (DOE) technique which is a six-sigma method to determine effects of parameters. As a result, it has been determined that the most important parameters affecting the evaporator performance among the selected parameters are found to be the refrigerant amount and pipe diameter. It has been determined that the minimum energy consumption is 6-mm pipe diameter and 16-g refrigerant. It has also been noted that the overall consumption of the experiment sample decreased by 16.6% with respect to the reference system, which has 7-mm pipe diameter and 18-g refrigerant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title="heat exchanger">heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=refrigerator" title=" refrigerator"> refrigerator</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption" title=" energy consumption"> energy consumption</a> </p> <a href="https://publications.waset.org/abstracts/105362/experimental-analysis-of-the-plate-on-tube-evaporator-on-a-domestic-refrigerators-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105362.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">153</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">14510</span> Comparison between FEM Simulation and Experiment of Temperature Rise in Power Transformer Inner Steel Plate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Byung%20hyun%20Bae">Byung hyun Bae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In power transformer, leakage magnetic flux generate temperature rise of inner steel plate.

The goal of the team's activities was to experiment with ways of fusing the two most common contemporary ways of referring to green installations, that is, either in a pure artistic or in an ecological manner, and creating a living, dynamic, interactive installation capable of both receiving and interpreting external factors, such as natural and human stimuli, that would not only determine some of the mechanism's presets. By consequent, a complex experiment made up of various research and project stages was elaborated in order to transform an idea into an actual interactive green installation within months thanks to the interaction, teamwork, and design processes undertaken throughout the academic years by both university lecturers and some of our students. The outcomes would lead to the development of a dynamic artwork called "Modgrew" as well as the introduction of experiment-based learning at the Timisoara Faculty of Architecture and Urban Planning, as well as at the Faculty of Electrical and Power Engineering, for the green wall automation issues. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20design" title="green design">green design</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20walls" title=" living walls"> living walls</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20structure" title=" modular structure"> modular structure</a>, <a href="https://publications.waset.org/abstracts/search?q=interactive%20proof%20of%20concept" title=" interactive proof of concept"> interactive proof of concept</a> </p> <a href="https://publications.waset.org/abstracts/166969/modular-responsive-and-interactive-green-walls-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166969.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">76</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">14508</span> Callus Induction of Segmented Corm Explant of Gladiolus cv.

In order to obtain callus from segmented corm which was obtained from in vitro culture, callus formation media were MS media supplemented with 4 levels of hormones such as 1.0 mg l-1 NAA + 0.5 mg l-1 BAP, 0.5 mg l-1 NAA + 0.25 mg l-1 BAP, 1.0 mg l-1 2, 4-D + 0.5 mg l-1 BAP, and 0.5 mg l-1 2, 4-D + 0.25 mg l-1 BAP. The results showed that the most weight of callus (2.28 g) was produced in MS callus formation media which were supplemented with 1.0 mg l-1 NAA + 0.5 mg l-1 BAP.

In second experiment for regeneration of callus, a factorial experiment in the form of randomized complete design with 12 treatments and 3 replications and each replication with six jars was carried out. The treatments consisted of callus culture media in 4 levels and regeneration culture media in 3 levels [control (no PGRs), MS with 0.2 mg l-1 BAP + 0.1 mg l-1 Kin + 0.01 mg l-1 NAA, and MS with 0.2 mg l-1 BAP + 0.05 mg l-1 Kin + 0.01 mg l-1 NAA].

However, the experiment instrumentation usually is expensive, and hence, each test implies a incremented in design cost. The aim of this work is to select and implement a low-cost static pressure data acquisition system for a NACA 2412 airfoil in an open cycle wind tunnel. This work compares wind tunnel experiment with Computational Fluid Dynamics (CFD) simulation and parametric analysis. The experiment was evaluated at Reynolds of 1.65 <em>e<sup>5</sup></em>, with increasing angles from -5° to 15°. The comparison between the approaches show good enough accuracy, between the experiment and CFD, additional parametric analysis results differ widely from the other methods, which complies with the lack of accuracy of the lateral approach due its simplicity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20tunnel" title="wind tunnel">wind tunnel</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20cost%20instrumentation" title=" low cost instrumentation"> low cost instrumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20testing" title=" experimental testing"> experimental testing</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20simulation" title=" CFD simulation"> CFD simulation</a> </p> <a href="https://publications.waset.org/abstracts/88363/implementation-of-a-low-cost-instrumentation-for-an-open-cycle-wind-tunnel-to-evaluate-pressure-coefficient" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88363.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">180</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">14505</span> Design and Optimization for a Compliant Gripper with Force Regulation Mechanism</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nhat%20Linh%20Ho">Nhat Linh Ho</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanh-Phong%20Dao"> Thanh-Phong Dao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shyh-Chour%20Huang"> Shyh-Chour Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hieu%20Giang%20Le"> Hieu Giang Le</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a design and optimization for a compliant gripper. The gripper is constructed based on the concept of compliant mechanism with flexure hinge. A passive force regulation mechanism is presented to control the grasping force a micro-sized object instead of using a sensor force. The force regulation mechanism is designed using the planar springs. The gripper is expected to obtain a large range of displacement to handle various sized objects. First of all, the statics and dynamics of the gripper are investigated by using the finite element analysis in ANSYS software. And then, the design parameters of the gripper are optimized via Taguchi method. An orthogonal array <em>L<sub>9</sub></em> is used to establish an experimental matrix. Subsequently, the signal to noise ratio is analyzed to find the optimal solution. Finally, the response surface methodology is employed to model the relationship between the design parameters and the output displacement of the gripper. The design of experiment method is then used to analyze the sensitivity so as to determine the effect of each parameter on the displacement. The results showed that the compliant gripper can move with a large displacement of 213.51 mm and the force regulation mechanism is expected to be used for high precision positioning systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexure%20hinge" title="flexure hinge">flexure hinge</a>, <a href="https://publications.waset.org/abstracts/search?q=compliant%20mechanism" title=" compliant mechanism"> compliant mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=compliant%20gripper" title=" compliant gripper"> compliant gripper</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20regulation%20mechanism" title=" force regulation mechanism"> force regulation mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a> </p> <a href="https://publications.waset.org/abstracts/61596/design-and-optimization-for-a-compliant-gripper-with-force-regulation-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61596.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">14504</span> Optimization of Dissolution of Chevreul’s Salt in Ammonium Chloride Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Sert%C3%A7elik">Mustafa Sertçelik</a>, <a href="https://publications.waset.org/abstracts/search?q=Hacali%20Necefo%C4%9Flu"> Hacali Necefoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Turan%20%C3%87alban"> Turan Çalban</a>, <a href="https://publications.waset.org/abstracts/search?q=Soner%20Ku%C5%9Flu"> Soner Kuşlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, Chevreul’s salt was dissolved in ammonium chloride solutions.

To study this, bead on plate welding is done by submerged arc welding on the sample plate of heavy duty mild steel of designation IS 2062 grade B, fitted on the special fixture ensuring the plate temperature at zero degree Celsius. Sixteen numbers of such samples are welded by varying the most influencing parameters viz. travel speed, voltage, wire feed rate and electrode stick-out at four different levels. Taguchi’s design of experiment is applied by selecting Taguchi's L16 orthogonal array to restrict the number of experimental runs. Cross sectioned samples are polished and etched to view the weldment. Finally, different zone of the weldment is observed by optical microscope. From the type of microstructure of weldment it is concluded that submerged arc welding is feasible at zero degree Celsius on mild steel plate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Submerged%20Arc%20Welding" title="Submerged Arc Welding">Submerged Arc Welding</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20degree%20Celsius" title=" zero degree Celsius"> zero degree Celsius</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%E2%80%99s%20design%20of%20experiment" title=" Taguchi’s design of experiment"> Taguchi’s design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure%20of%20weldment" title=" microstructure of weldment"> microstructure of weldment</a> </p> <a href="https://publications.waset.org/abstracts/20873/study-of-microstructure-of-weldment-obtained-by-submerged-arc-welding-saw-on-is-2062-grade-b-mild-steel-plate-at-zero-degree-celsius" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20873.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">440</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">14502</span> Experimental Investigation for the Overtopping Wave Force of the Vertical Breakwater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Song%20Gui">Jin Song Gui</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Li"> Han Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Jin%20Zhang"> Rui Jin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Heng%20Jiang%20Cai"> Heng Jiang Cai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is a large deviation between the measured wave power at the vertical breast wall and the calculated one according to current specification in the case of overtopping. In order to investigate the reasons for the deviation, the wave forces of vertical breast wall under overtopping conditions have been measured through physical model experiment and compared with the calculated results. The effect of water depth, period and the wave height on the wave forces of the vertical breast wall have been also investigated. The distribution of wave pressure under different wave actions was tested based on the force sensor which is installed in the vertical breakwater. By comparing and analyzing the measured values and norms calculated values, the applicability of the existing norms recommended method were discussed and a reference for the design of vertical breakwater was provided. Experiment results show that with the decrease of the water depth, the gap is growing between the actual wave forces and the specification values, and there are no obvious regulations between these two values with the variation of period while wave force greatly reduces with the overtopping reducing. The amount of water depth and wave overtopping has a significant impact on the wave force of overtopping section while the period has no obvious influence on the wave force. Finally, some favorable recommendations for the overtopping wave force design of the vertical breakwater according to the model experiment results are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=overtopping%20wave" title="overtopping wave">overtopping wave</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20model%20experiment" title=" physical model experiment"> physical model experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20breakwater" title=" vertical breakwater"> vertical breakwater</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20forces" title=" wave forces"> wave forces</a> </p> <a href="https://publications.waset.org/abstracts/47386/experimental-investigation-for-the-overtopping-wave-force-of-the-vertical-breakwater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47386.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">303</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">14501</span> Fengqiao: An Ongoing Experiment with 'UrbanMemory' Theory in an Ancient Town and ItsDesign Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yibei%20Ye">Yibei Ye</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Xu"> Lei Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhenyu%20Cao"> Zhenyu Cao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ancient town is a unique carrier of urban culture, maintaining the core culture of a region and continuing the urban context. Fengqiao, a nearly 2000-year-old town was on the brink of dilapidation in the past few decades. The town faced such problems as poor construction quality, environmental degeneration, inadequate open space, cultural characteristics and industry vitality. Therefore, the research upholds the principle of ‘organic renewal’ and puts forward three practical updated strategies which are ‘Repair Old as Ever,' ‘Activate Function’ and ‘Fill in with The New’. Also as a participant in updating the design, the author aims to ‘keep the memory of the history and see the development of the present’ as the goal of updating the design and regards the process of town renewal as the experimental venue for realizing this purpose. The research will sum up innovations on the designing process and the engineering progress in the past two years, and find out the innovation experiment and the effect of its implementation on the methodological level of the organic renewal design in Fengqiao ancient town. From here, we can also enjoy the very characteristic development trend presented by China in the design practice of the organic renewal in the ancient town. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=characteristic%20town" title="characteristic town">characteristic town</a>, <a href="https://publications.waset.org/abstracts/search?q=Fengqiao" title=" Fengqiao"> Fengqiao</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20renewal" title=" organic renewal"> organic renewal</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20memory" title=" urban memory"> urban memory</a> </p> <a href="https://publications.waset.org/abstracts/84753/fengqiao-an-ongoing-experiment-with-urbanmemory-theory-in-an-ancient-town-and-itsdesign-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84753.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">159</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">14500</span> Direct Design of Steel Bridge Using Nonlinear Inelastic Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boo-Sung%20Koh">Boo-Sung Koh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung-Eock%20Kim"> Seung-Eock Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a direct design using a nonlinear inelastic analysis is suggested.

FLP has been widely studied in various limited spaces and workflows. For example, cafeterias with many types of equipment for troops cause chaotic processes when dining. OBJECTIVE: This article tried to optimize the layout of troops’ cafeteria and to improve the overall efficiency of the dining process. METHODS: First, the original cafeteria layout design scheme was analyzed from an ergonomic perspective and two new design schemes were generated. Next, three facility layout models were designed, and further simulation was applied to compare the total time and density of troops between each scheme. Last, an experiment of the dining process with video observation and analysis verified the simulation results. RESULTS: In a simulation, the dining time under the second new layout is shortened by 2.25% and 1.89% (p<0.0001, p=0.0001) compared with the other two layouts, while troops-flow density and interference both greatly reduced in the two new layouts. In the experiment, process completing time and the number of interference reduced as well, which verified corresponding simulation results. CONCLUSIONS: Our two new layout schemes are tested to be optimal by a series of simulation and space experiments. In future research, similar approaches could be applied when taking layout-design algorithm calculation into consideration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=layout%20optimization" title="layout optimization">layout optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=dining%20efficiency" title=" dining efficiency"> dining efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=troops%E2%80%99%20cafeteria" title=" troops’ cafeteria"> troops’ cafeteria</a>, <a href="https://publications.waset.org/abstracts/search?q=anylogic%20simulation" title=" anylogic simulation"> anylogic simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20experiment" title=" field experiment"> field experiment</a> </p> <a href="https://publications.waset.org/abstracts/143500/research-on-the-optimization-of-the-facility-layout-of-efficient-cafeterias-for-troops" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143500.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">143</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">14497</span> Virtual Chemistry Laboratory as Pre-Lab Experiences: Stimulating Student's Prediction Skill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yenni%20Kurniawati">Yenni Kurniawati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Students Prediction Skill in chemistry experiments is an important skill for pre-service chemistry students to stimulate students reflective thinking at each stage of many chemistry experiments, qualitatively and quantitatively. A Virtual Chemistry Laboratory was designed to give students opportunities and times to practicing many kinds of chemistry experiments repeatedly, everywhere and anytime, before they do a real experiment. The Virtual Chemistry Laboratory content was constructed using the Model of Educational Reconstruction and developed to enhance students ability to predicted the experiment results and analyzed the cause of error, calculating the accuracy and precision with carefully in using chemicals. This research showed students changing in making a decision and extremely beware with accuracy, but still had a low concern in precision. It enhancing students level of reflective thinking skill related to their prediction skill 1 until 2 stage in average. Most of them could predict the characteristics of the product in experiment, and even the result will going to be an error. In addition, they take experiments more seriously and curiously about the experiment results.

A refrigerator designed to work with R134a was used for this experiment, the capillary for this experiment was not varied at anytime during the experiment. 40, 60, 80g, charge of R600a were tested against 100 g of R134a under the designed capillary length of the refrigerator, and the performance using R600a was evaluated and compared with its performance when R134a was used. The results obtained showed that the design temperature and pull-down time set by International Standard Organisation (ISO) for small refrigerator was achieved using both 80g of R600a and 100g of R134a but R134a has earlier pulled down time than using R600a. The average coefficient of performance (COP) obtained using R600a is 17.7% higher than that of R134a while the average power consumption is 42.5 % lower than R134a, which shows that R600a can be used as replacement for R134a in domestic refrigerator without necessarily need to modified the capillary. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=domestic%20refrigerator" title="domestic refrigerator">domestic refrigerator</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental" title=" experimental"> experimental</a>, <a href="https://publications.waset.org/abstracts/search?q=R600a" title=" R600a"> R600a</a>, <a href="https://publications.waset.org/abstracts/search?q=R134a" title=" R134a"> R134a</a> </p> <a href="https://publications.waset.org/abstracts/26285/experimental-investigation-of-r600a-as-a-retrofit-for-r134a-in-a-household-refrigerator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26285.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">520</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">14494</span> Modeling and Optimization of Algae Oil Extraction Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20F.%20Ejim">I.

The effects of extraction solvent concentration, extraction time and temperature on the yield and quality of oil were studied using Response Surface Methodology (RSM). Experimental Design: Optimization of algae oil extraction using Box-Behnken design was used to generate 17 experimental runs in a three-factor-three-level design where oil yield, specific gravity, acid value and saponification value were evaluated as the response. Result: In this result, a minimum oil yield of 17% and maximum of 44% was realized. The optimum values for yield, specific gravity, acid value and saponification value from the overlay plot were 40.79%, 0.8788, 0.5056 mg KOH/g and 180.78 mg KOH/g respectively with desirability of 0.801. The maximum point prediction was yield 40.79% at solvent concentration 66.68 n-hexane, temperature of 40.0°C and extraction time of 4 hrs. Analysis of Variance (ANOVA) results showed that the linear and quadratic coefficient were all significant at p<0.05. The experiment was validated and results obtained were with the predicted values. Conclusion: Algae oil extraction was successfully optimized using RSM and its quality indicated it is suitable for many industrial uses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algae%20oil" title="algae oil">algae oil</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=Box-Bohnken" title=" Box-Bohnken"> Box-Bohnken</a>, <a href="https://publications.waset.org/abstracts/search?q=extraction" title=" extraction"> extraction</a> </p> <a href="https://publications.waset.org/abstracts/5831/modeling-and-optimization-of-algae-oil-extraction-using-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5831.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">338</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">14493</span> Motor Controller Implementation Using Model Based Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cau%20Tran">Cau Tran</a>, <a href="https://publications.waset.org/abstracts/search?q=Tu%20Nguyen"> Tu Nguyen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tien%20Pham"> Tien Pham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Model-based design (MBD) is a mathematical and visual technique for addressing design issues in the fields of communications, signal processing, and complicated control systems. It is utilized in several automotive, aerospace, industrial, and motion control applications. Virtual models are at the center of the software development process with model based design. A method used in the creation of embedded software is model-based design. In this study, the LAT motor is modeled in a simulation environment, and the LAT motor control is designed with a cascade structure, a speed and current control loop, and a controller that is used in the next part. A PID structure serves as this controller. Based on techniques and motor parameters that match the design goals, the PID controller is created for the model using traditional design principles. The MBD approach will be used to build embedded software for motor control. The paper will be divided into three distinct sections. The first section will introduce the design process and the benefits and drawbacks of the MBD technique. The design of control software for LAT motors will be the main topic of the next section. The experiment's results are the subject of the last section. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=model%20based%20design"
