However, the weak point is most often the fiber/matrix interface, which can reduce the durability of the composite material. To solve this problem, it is essential to control the interphase and improve our understanding of the adhesion mechanism at the fibre/matrix interface. The interphase properties depend on the nature of the sizing applied on the surface of the glass fibers during their manufacture in order to protect them, facilitate their handling, and ensure fibre/matrix adhesion. The sizing composition, and in particular the nature of the coupling agent and the film-former affects the mechanical properties and the durability of composites. The aim of our study is, therefore, to develop and study composite materials with simplified sizing systems in order to understand how the main constituents modify the mechanical properties and the durability of composites from the nanometric to the macroscopic scale. Two model systems were elaborated: an epoxy matrix reinforced with simplified-sized glass fibres and an epoxy coating applied on glass substrates treated with the same sizings as fibres. For the sizing composition, two configurations were chosen. The first configuration possesses a chemical reactivity to link the glass and the matrix, and the second sizing contains non-reactive agents. The chemistry of the sized glass substrates and fibers was analyzed by FT-IR and XPS spectroscopies. The surface morphology was characterized by SEM and AFM microscopies. The observation of the surface samples reveals the presence of sizings which morphology depends on their chemistry. The evaluation of adhesion of coated substrates and composite materials show good interfacial properties for the reactive configuration. However, the non-reactive configuration exhibits an adhesive rupture at the interface of glass/epoxy for both systems. The interfaces and interphases between the matrix and the substrates are characterized at different scales. Correlations are made between the initial properties of the sizings and the mechanical performances of the model composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesion" title="adhesion">adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=interphase" title=" interphase"> interphase</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20composite" title=" materials composite"> materials composite</a>, <a href="https://publications.waset.org/abstracts/search?q=simplified%20sizing%20systems" title=" simplified sizing systems"> simplified sizing systems</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20properties" title=" surface properties"> surface properties</a> </p> <a href="https://publications.waset.org/abstracts/135193/modulation-of-the-interphase-in-a-glass-epoxy-system-influence-of-the-sizing-chemistry-on-adhesion-and-interfacial-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1208</span> Micromechanical Determination of the Mechanical Properties of Carbon Nanotube-Polymer Composites with a Functionally Graded Interphase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahidullah%20Tac">Vahidullah Tac</a>, <a href="https://publications.waset.org/abstracts/search?q=Ercan%20Gurses"> Ercan Gurses</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There have been numerous attempts at modelling carbon nanotube – polymer composites micromechanically in recent years, albeit to limited success. One of the major setbacks of the models used in the scientific community is the lack of regard to the different phases present in a nanocomposite. We employ a multi-phase micromechanical model that allows functionally grading certain phases to determine the mechanical properties of nanocomposites. The model has four distinct phases; the nanotube, the interface between the nanotube and polymer, the interphase, and the bulk matrix. Among the four phases, the interphase is functionally graded such that its moduli gradually decrease from some predetermined values to those of the bulk polymer. We find that the interface plays little role in stiffening/softening of the polymer per se , but instead, it is responsible for load transfer between the polymer and the carbon nanotube. Our results indicate that the carbon nanotube, as well as the interphase, have significant roles in stiffening the composite. The results are then compared to experimental findings and the interphase is tuned accordingly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title="carbon nanotube">carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=interphase" title=" interphase"> interphase</a>, <a href="https://publications.waset.org/abstracts/search?q=micromechanical%20modeling" title=" micromechanical modeling"> micromechanical modeling</a> </p> <a href="https://publications.waset.org/abstracts/93783/micromechanical-determination-of-the-mechanical-properties-of-carbon-nanotube-polymer-composites-with-a-functionally-graded-interphase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93783.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">166</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">1207</span> The Smart Record and Replay Mechanism for Android</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kuei-Chun%20Liu">Kuei-Chun Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Yu%20Lai"> Yu-Yu Lai</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching-Hong%20Wu"> Ching-Hong Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hsiao-Han%20Huang"> Hsiao-Han Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The number of Android applications (Apps) has increased rapidly in recent years. In order to get better programmatic control over Apps, we designed a record-and-replay mechanism to record Android input events and accessibility service events then make shortcuts. The shortcut is useful for complicated routine works and to Android beginners. We also generated graphical user interface (GUI) API by these shortcuts. GUI API helps developers make integrated Apps which can control other third-party Apps even if the official API is not offered by their providers. We demonstrated the usage of GUI API with two integrated Apps: Universal Bank App and Universal Communication App. Universal Bank App integrates three accounts from different banks and Universal Communication App integrates Line with WhatsApp. Both of them show the advantage of extendable GUI API. Furthermore, using our mechanism, shortcuts could replay almost all of the Top-100 Apps on Google Play correctly. In sum, the approach we present can help both Android developers and general users. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphical%20user%20interface" title="graphical user interface">graphical user interface</a>, <a href="https://publications.waset.org/abstracts/search?q=GUI%20API" title=" GUI API"> GUI API</a>, <a href="https://publications.waset.org/abstracts/search?q=record-and-replay" title=" record-and-replay"> record-and-replay</a>, <a href="https://publications.waset.org/abstracts/search?q=third-party%20apps" title=" third-party apps"> third-party apps</a> </p> <a href="https://publications.waset.org/abstracts/44813/the-smart-record-and-replay-mechanism-for-android" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44813.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">408</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1206</span> Modeling Reflection and Transmission of Elastodiffussive Wave Sata Semiconductor Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amit%20Sharma">Amit Sharma</a>, <a href="https://publications.waset.org/abstracts/search?q=J.%20N.%20Sharma"> J.

The amplitude ratios (reflection and transmission coefficients) of reflected and transmitted waves to that of incident wave varying with the incident angles have been examined for the case of quasi-longitudinal wave. The special cases of normal and grazing incidence have also been derived with the help of Gauss elimination method. The mathematical model consisting of governing partial differential equations of motion and charge carriers diffusion of n-type semiconductors and elastic solid has been solved both analytically and numerically in the study. The numerical computations of reflection and transmission coefficients has been carried out by using MATLAB programming software for silicon (Si) semiconductor and copper elastic solid. The computer simulated results have been plotted graphically for Si semiconductors. The study may be useful in semiconductors, geology, and seismology in addition to surface acoustic wave (SAW) devices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=quasilongitudinal" title="quasilongitudinal">quasilongitudinal</a>, <a href="https://publications.waset.org/abstracts/search?q=reflection%20and%20transmission" title=" reflection and transmission"> reflection and transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=semiconductors" title=" semiconductors"> semiconductors</a>, <a href="https://publications.waset.org/abstracts/search?q=acoustics" title=" acoustics"> acoustics</a> </p> <a href="https://publications.waset.org/abstracts/3008/modeling-reflection-and-transmission-of-elastodiffussive-wave-sata-semiconductor-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">391</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1205</span> Application of Electrochemical Impedance Spectroscopy to Monitor the Steel/Soil Interface During Cathodic Protection of Steel in Simulated Soil Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mandlenkosi%20George%20Robert%20Mahlobo">Mandlenkosi George Robert Mahlobo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tumelo%20Seadira"> Tumelo Seadira</a>, <a href="https://publications.waset.org/abstracts/search?q=Major%20Melusi%20Mabuza"> Major Melusi Mabuza</a>, <a href="https://publications.waset.org/abstracts/search?q=Peter%20Apata%20Olubambi"> Peter Apata Olubambi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cathodic protection (CP) has been widely considered a suitable technique for mitigating corrosion of buried metal structures. Plenty of efforts have been made in developing techniques, in particular non-destructive techniques, for monitoring and quantifying the effectiveness of CP to ensure the sustainability and performance of buried steel structures. The aim of this study was to investigate the evolution of the electrochemical processes at the steel/soil interface during the application of CP on steel in simulated soil. Carbon steel was subjected to electrochemical tests with NS4 solution used as simulated soil conditions for 4 days before applying CP for a further 11 days. A previously modified non-destructive voltammetry technique was applied before and after the application of CP to measure the corrosion rate. Electrochemical impedance spectroscopy (EIS), in combination with mathematical modeling through equivalent electric circuits, was applied to determine the electrochemical behavior at the steel/soil interface. The measured corrosion rate was found to have decreased from 410 µm/yr to 8 µm/yr between days 5 and 14 because of the applied CP. Equivalent electrical circuits were successfully constructed and used to adequately model the EIS results. The modeling of the obtained EIS results revealed the formation of corrosion products via a mixed activation-diffusion mechanism during the first 4 days, while the activation mechanism prevailed in the presence of CP, resulting in a protective film. The x-ray diffraction analysis confirmed the presence of corrosion products and the predominant protective film corresponding to the calcareous deposit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20steel" title="carbon steel">carbon steel</a>, <a href="https://publications.waset.org/abstracts/search?q=cathodic%20protection" title=" cathodic protection"> cathodic protection</a>, <a href="https://publications.waset.org/abstracts/search?q=NS4%20solution" title=" NS4 solution"> NS4 solution</a>, <a href="https://publications.waset.org/abstracts/search?q=voltammetry" title=" voltammetry"> voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=EIS" title=" EIS"> EIS</a> </p> <a href="https://publications.waset.org/abstracts/182962/application-of-electrochemical-impedance-spectroscopy-to-monitor-the-steelsoil-interface-during-cathodic-protection-of-steel-in-simulated-soil-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182962.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">64</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">1204</span> Laser-TIG Welding-Brazing for Dissimilar Metals between Aluminum Alloy and Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiangfang%20Xu">Xiangfang Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bintao%20Wu"> Bintao Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yugang%20Miao"> Yugang Miao</a>, <a href="https://publications.waset.org/abstracts/search?q=Duanfeng%20Han"> Duanfeng Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Experiments were conducted on 5A06 aluminum alloy and Q235 steel using the laser-TIG hybrid heat source welding-brazing method to realize the reliable connection of Al/Fe dissimilar metals and the welding characteristics were analyzed. It was found that the joints with uniform seam and high tensile strength could be obtained using such a method, while the welding process demanded special welding parameters. Spectrum measurements showed that the Al and Fe atoms diffused more thoroughly at the brazing interface and formed a 3μm-thick intermetallic compound layer at the Al/Fe joints brazed connection interface. Shearing tests indicated that the shearing strength of the Al/Fe welding-brazed joint was 165MPa.

A meshless particle method, smooth particle hydrodynamics (SPH) has great advantages in dealing with complex interface and multiphase coupling problems. This study presents an improved soil‒water coupled model to simulate LGIW problems based on an open source code DualSPHysics (v4.0). Aiming to solve the low efficiency problem in modeling real large-scale LGIW problems, graphics processing unit (GPU) acceleration technology is implemented into this code. An experimental example, subaerial landslide-generated water waves, is simulated to demonstrate the accuracy of this model. Then, the Huangtian LGIW, a real large-scale LGIW problem is modeled to reproduce the entire disaster chain, including landslide dynamics, fluid‒solid interaction, and surge wave generation. The convergence analysis shows that a particle distance of 5.0 m can provide a converged landslide deposit and surge wave for this example. Numerical simulation results are in good agreement with the limited field survey data. The application example of the Huangtian LGIW provides a typical reference for large-scale LGIW assessments, which can provide reliable information on landslide dynamics, interface coupling behavior, and surge wave characteristics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%E2%80%92water%20coupling" title="soil‒water coupling">soil‒water coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=landslide-generated%20impulse%20wave" title=" landslide-generated impulse wave"> landslide-generated impulse wave</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale" title=" large-scale"> large-scale</a>, <a href="https://publications.waset.org/abstracts/search?q=SPH" title=" SPH"> SPH</a> </p> <a href="https://publications.waset.org/abstracts/179371/numerical-simulation-of-large-scale-landslide-generated-impulse-waves-with-a-soilwater-coupling-smooth-particle-hydrodynamics-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179371.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">64</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">1202</span> Preparation and Study of Pluronic F127 Monolayers at Air-Water Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neha%20Kanodia">Neha Kanodia</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Kamil"> M.

Pluronic F127 is a triblock copolymer of poly (ethyleneoxide) (PEO groups)– poly (propylene oxide) (PO groups)–poly(ethylene oxide) (PEO groups). Surface pressure versus mean molecular area isotherms is studied. The isotherm of the mono layer showed the characteristics of a pancake-to-brush transition upon compression of the mono layer. The effect of adding surfactant (SDS) to polymer and the effect of increasing loading on polymer was also studied. The effect of repeated compression and expansion cycle (or hysteresis curve) is investigated to know about stability of the film formed. Static elasticity of mono layer gives information about molecular arrangement, phase structure and phase transition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface-pressure" title="surface-pressure">surface-pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20molecular%20area%20isotherms" title=" mean molecular area isotherms"> mean molecular area isotherms</a>, <a href="https://publications.waset.org/abstracts/search?q=hysteresis" title=" hysteresis"> hysteresis</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20elasticity" title=" static elasticity"> static elasticity</a> </p> <a href="https://publications.waset.org/abstracts/19248/preparation-and-study-of-pluronic-f127-monolayers-at-air-water-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19248.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">449</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">1201</span> Plasma Spraying of 316 Stainless Steel on Aluminum and Investigation of Coat/Substrate Interface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Abachi">P.

Since the layer adhesion of the coating influences the mechanical integrity of the coat/substrate interface during the service time, it should be examined accurately. At the present work, the tensile bonding strength of the 316 stainless steel plasma sprayed coating on aluminum substrate was determined by using tensile adhesion test, TAT, specimen. The interfacial fracture toughness was specified using four-point bend specimen containing a saw notch and modified chevron-notched short-bar (SB) specimen. The coating microstructure and fractured specimen surface were examined by using scanning electron- and optical-microscopy. The investigation of coated surface after tensile adhesion test indicates that the failure mechanism is mostly cohesive and rarely adhesive type. The calculated value of critical strain energy release rate proposes relatively good interface status. It seems that four<strong>-</strong>point bending test offers a potentially more sensitive means for evaluation of mechanical integrity of coating/substrate interfaces than is possible with the tensile test. The fracture toughness value reported for the modified chevron-notched short-bar specimen testing cannot be taken as absolute value because its calculation is based on the minimum stress intensity coefficient value which has been suggested for the fracture toughness determination of homogeneous parts in the ASTM E1304-97 standard.  <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bonding%20strength" title="bonding strength">bonding strength</a>, <a href="https://publications.waset.org/abstracts/search?q=four-point%20bend%20test" title=" four-point bend test"> four-point bend test</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20fracture%20toughness" title=" interfacial fracture toughness"> interfacial fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20chevron-notched%20short-bar%20specimen" title=" modified chevron-notched short-bar specimen"> modified chevron-notched short-bar specimen</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20sprayed%20coating" title=" plasma sprayed coating"> plasma sprayed coating</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20adhesion%20test" title=" tensile adhesion test"> tensile adhesion test</a> </p> <a href="https://publications.waset.org/abstracts/46136/plasma-spraying-of-316-stainless-steel-on-aluminum-and-investigation-of-coatsubstrate-interface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46136.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">1200</span> Modeling Electrical Properties of Hetero-Junction-Graphene/Pentacene and Gold/Pentacene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20K.%20Lamba">V.

Further, we studied the effect of ripples/bends in pentacene using NEGF-DFT approach. Current transport across the pentacene/graphene interface is found to be remarkably different from transport across pentacene/Gold interfaces. We found that current across these interfaces could be accurately modeled by a combination of thermionic and Poole–Frenkel emission. Further, the degree of bend or degrees of the curve formed during ripple formation strongly change the optimized geometric structures, charge distributions, energy bands, and DOS. The misorientation and hybridization of carbon orbitals are associated with a variation in bond lengths and carrier densities, and are the causes of the dramatic changes in the electronic structure during ripple formation. The electrical conductivity decreases with increase in curvature during ripple formation or due to bending of pentacene molecule and a decrease in conductivity is directly proportional to the increase in curvature angle and given by quadratic relation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hetero-junction" title="hetero-junction">hetero-junction</a>, <a href="https://publications.waset.org/abstracts/search?q=grapheme" title=" grapheme"> grapheme</a>, <a href="https://publications.waset.org/abstracts/search?q=NEGF-DFT" title=" NEGF-DFT"> NEGF-DFT</a>, <a href="https://publications.waset.org/abstracts/search?q=pentacene" title=" pentacene"> pentacene</a>, <a href="https://publications.waset.org/abstracts/search?q=gold%2Fpentacene" title=" gold/pentacene"> gold/pentacene</a> </p> <a href="https://publications.waset.org/abstracts/56132/modeling-electrical-properties-of-hetero-junction-graphenepentacene-and-goldpentacene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56132.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">232</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">1199</span> Research of Amplitude-Frequency Characteristics of Nonlinear Oscillations of the Interface of Two-Layered Liquid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Win%20Ko%20Ko">Win Ko Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20N.%20Temnov"> A.

Using two basic asymmetric harmonics excited in two mutually perpendicular planes, ordinary differential equations of nonlinear oscillations of the interface of a two-layer liquid are investigated. In this paper, hydrodynamic coefficients of linear and nonlinear problems in integral relations were determined. As a result, the instability regions of forced oscillations of a two-layered liquid in a cylindrical tank occurring in the plane of action of the disturbing force are constructed, as well as the dynamic instability regions of the parametric resonance for different ratios of densities of the upper and lower liquids depending on the amplitudes of liquids from the excitations frequencies. Steady-state regimes of fluid motion were found in the regions of dynamic instability of the initial oscillation form. The Bubnov-Galerkin method is used to construct instability regions for approximate solution of nonlinear differential equations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20oscillations" title="nonlinear oscillations">nonlinear oscillations</a>, <a href="https://publications.waset.org/abstracts/search?q=two-layered%20liquid" title=" two-layered liquid"> two-layered liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=instability%20region" title=" instability region"> instability region</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic%20coefficients" title=" hydrodynamic coefficients"> hydrodynamic coefficients</a>, <a href="https://publications.waset.org/abstracts/search?q=resonance%20frequency" title=" resonance frequency"> resonance frequency</a> </p> <a href="https://publications.waset.org/abstracts/115967/research-of-amplitude-frequency-characteristics-of-nonlinear-oscillations-of-the-interface-of-two-layered-liquid" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115967.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">219</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">1198</span> Inertial Motion Capture System for Biomechanical Analysis in Rehabilitation and Sports</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mario%20Sandro%20F.%20Rocha">Mario Sandro F.

The inertial measuring units (IMUs), composed by accelerometers, gyroscopes, and magnetometers, are able to measure spatial orientations and calculate displacements with sufficient precision for applications in biomechanical analysis of movement. Furthermore, this type of system is relatively affordable and has the advantages of portability and independence from external references. In this work, we present the last version of our inertial motion capture system, based on the foregoing technology, with a unity interface designed for rehabilitation and sports. In our hardware architecture, only one serial port is required. First, the board client must be connected to the computer by a USB cable. Next, an available serial port is configured and opened to establish the communication between the client and the application, and then the client starts scanning for the active MOCAP_S servers around. The servers play the role of the inertial measuring units that capture the movements of the body and send the data to the client, which in turn create a package composed by the ID of the server, the current timestamp, and the motion capture data defined in the client pre-configuration of the capture session. In the current version, we can measure the game rotation vector (grv) and linear acceleration (lacc), and we also have a step detector that can be abled or disabled. The grv data are processed and directly linked to the bones of the 3D model, and, along with the data of lacc and step detector, they are also used to perform the calculations of displacements and other variables shown on the graphical user interface. Our user interface was designed to calculate and present variables that are important for rehabilitation and sports, such as cadence, speed, total gait cycle, gait cycle length, obliquity and rotation, and center of gravity displacement. Our goal is to present a low-cost portable and wearable system with a friendly interface for application in biomechanics and sports, which also performs as a product of high precision and low consumption of energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title="biomechanics">biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=inertial%20sensors" title=" inertial sensors"> inertial sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=motion%20capture" title=" motion capture"> motion capture</a>, <a href="https://publications.waset.org/abstracts/search?q=rehabilitation" title=" rehabilitation"> rehabilitation</a> </p> <a href="https://publications.waset.org/abstracts/112465/inertial-motion-capture-system-for-biomechanical-analysis-in-rehabilitation-and-sports" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112465.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">140</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">1197</span> Formation of Chemical Compound Layer at the Interface of Initial Substances A and B with Dominance of Diffusion of the A Atoms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pavlo%20Selyshchev">Pavlo Selyshchev</a>, <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Akintunde"> Samuel Akintunde</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A theoretical approach to consider formation of chemical compound layer at the interface between initial substances A and B due to the interfacial interaction and diffusion is developed. It is considered situation when speed of interfacial interaction is large enough and diffusion of A-atoms through AB-layer is much more then diffusion of B-atoms. Atoms from A-layer diffuse toward B-atoms and form AB-atoms on the surface of B-layer. B-atoms are assumed to be immobile. The growth kinetics of the AB-layer is described by two differential equations with non-linear coupling, producing a good fit to the experimental data. It is shown that growth of the thickness of the AB-layer determines by dependence of chemical reaction rate on reactants concentration. In special case the thickness of the AB-layer can grow linearly or parabolically depending on that which of processes (interaction or the diffusion) controls the growth. The thickness of AB-layer as function of time is obtained. The moment of time (transition point) at which the linear growth are changed by parabolic is found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20formation" title="phase formation">phase formation</a>, <a href="https://publications.waset.org/abstracts/search?q=binary%20systems" title=" binary systems"> binary systems</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20reaction" title=" interfacial reaction"> interfacial reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=diffusion" title=" diffusion"> diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=compound%20layers" title=" compound layers"> compound layers</a>, <a href="https://publications.waset.org/abstracts/search?q=growth%20kinetics" title=" growth kinetics"> growth kinetics</a> </p> <a href="https://publications.waset.org/abstracts/10901/formation-of-chemical-compound-layer-at-the-interface-of-initial-substances-a-and-b-with-dominance-of-diffusion-of-the-a-atoms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10901.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">571</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">1196</span> Scaling Analysis of the Contact Line and Capillary Interaction Induced by a Floating Tilted Cylinder</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=ShiQing%20Gao">ShiQing Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=XingYi%20Zhang"> XingYi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=YouHe%20Zhou"> YouHe Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When a floating tilted cylinder pierces a fluid interface, the fulfilment of constant-contact-angle condition along the cylinder results in shift, stretch and distortion of the contact line, thus leading to a capillary interaction. We perform an investigation of the scaling dependence of tilt angle, contact angle, and cylinder radius on the contact line profile and the corresponding capillary interaction by numerical simulation and experiment. Characterized by three characteristic parameters respectively, the dependences for each deformation mode are systematically analyzed. Both the experiment and simulation reveals an invariant structure that is independent of contact angle and radius to characterize the stretch of the contact line for every tilted case. Based on this observation, we then propose a general capillary force scaling law to incredibly grasp all the simulated results, by simply approximating the contact line profile as tilted ellipse. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas-liquid%2Fliquid-fluid%20interface" title="gas-liquid/liquid-fluid interface">gas-liquid/liquid-fluid interface</a>, <a href="https://publications.waset.org/abstracts/search?q=colloidal%20particle" title=" colloidal particle"> colloidal particle</a>, <a href="https://publications.waset.org/abstracts/search?q=contact%20line%20shape" title=" contact line shape"> contact line shape</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20interaction" title=" capillary interaction"> capillary interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20evolver%20%28SE%29" title=" surface evolver (SE)"> surface evolver (SE)</a> </p> <a href="https://publications.waset.org/abstracts/53570/scaling-analysis-of-the-contact-line-and-capillary-interaction-induced-by-a-floating-tilted-cylinder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53570.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">282</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">1195</span> An Investigation on Interface Shear Resistance of Twinwall Units for Tank Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaylina%20Rana">Jaylina Rana</a>, <a href="https://publications.waset.org/abstracts/search?q=Chanakya%20Arya"> Chanakya Arya</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Stehle"> John Stehle</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hybrid precast twinwall concrete units, mainly used in basement, core and crosswall construction, are now being adopted in water retaining tank structures. Their use offers many advantages compared with conventional in-situ concrete alternatives, however, the design could be optimised further via a deeper understanding of the unique load transfer mechanisms in the system. In the tank application, twinwall units, which consist of two precast concrete biscuits connected by steel lattices and in-situ concrete core, are subject to bending. Uncertainties about the degree of composite action between the precast biscuits and hence flexural performance of the units necessitated laboratory tests to investigate the interface shear resistance. Testing was also required to assess both the leakage performance and buildability of a variety of joint details.

It is a visual gesture language that makes use of either one hand or both hands, arms, face, body to convey meanings and thoughts. SL automation system is an effective way which provides an interface to communicate with normal people using a computer. In this paper, an avatar based dictionary has been proposed for text to Indian Sign Language (ISL) generation system. This research work will also depict a literature review on SL corpus available for various SL s over the years. For ISL generation system, a written form of SL is required and there are certain techniques available for writing the SL. The system uses Hamburg sign language Notation System (HamNoSys) and Signing Gesture Mark-up Language (SiGML) for ISL generation. It is developed in PHP using Web Graphics Library (WebGL) technology for 3D avatar animation. A multilingual ISL dictionary is developed using HamNoSys for both English and Hindi Language. This dictionary will be used as a database to associate signs with words or phrases of a spoken language. It provides an interface for admin panel to manage the dictionary, i.e., modification, addition, or deletion of a word. Through this interface, HamNoSys can be developed and stored in a database and these notations can be converted into its corresponding SiGML file manually. The system takes natural language input sentence in English and Hindi language and generate 3D sign animation using an avatar. SL generation systems have potential applications in many domains such as healthcare sector, media, educational institutes, commercial sectors, transportation services etc. This research work will help the researchers to understand various techniques used for writing SL and generation of Sign Language systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avatar" title="avatar">avatar</a>, <a href="https://publications.waset.org/abstracts/search?q=dictionary" title=" dictionary"> dictionary</a>, <a href="https://publications.waset.org/abstracts/search?q=HamNoSys" title=" HamNoSys"> HamNoSys</a>, <a href="https://publications.waset.org/abstracts/search?q=hearing%20impaired" title=" hearing impaired"> hearing impaired</a>, <a href="https://publications.waset.org/abstracts/search?q=Indian%20sign%20language%20%28ISL%29" title=" Indian sign language (ISL)"> Indian sign language (ISL)</a>, <a href="https://publications.waset.org/abstracts/search?q=sign%20language" title=" sign language"> sign language</a> </p> <a href="https://publications.waset.org/abstracts/88342/online-multilingual-dictionary-using-hamburg-notation-for-avatar-based-indian-sign-language-generation-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88342.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">230</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">1192</span> Polyhedral Oligomeric Silsesquioxane in Poly Lactic Acid and Poly Butylene Adipate-Co-Terephthalate Blend</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elahe%20Moradi">Elahe Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hoseinali%20A.%20Khonakdar"> Hoseinali A.

Specifically, we enhanced the compatibility between two immiscible polymers, namely poly (lactic acid) (PLA) and poly (butylene adipate-co-terephthalate) (PBAT). Our strategy involved the use of polyhedral oligomeric silsesquioxanes (POSS) nanoparticles, equipped with an epoxy functional group (Epoxy-POSS), to accomplish this objective with solution casting method. The incorporation of 1% nanoparticles into the PLA blend resulted in a decrease in its cold crystallization temperature. Furthermore, these nanoparticles possess the requisite capability to enhance molecular mobility, facilitated by the induction of a lubrication effect. The emergence of a PLA-CO-POSS-CO-PBAT structure at the interface between PLA and PBAT led to a significant amplification of the interactions at the interface of the matrix and the dispersed phase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compatibilization" title="compatibilization">compatibilization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20behavior" title=" thermal behavior"> thermal behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=structure-properties" title=" structure-properties"> structure-properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=PLA" title=" PLA"> PLA</a>, <a href="https://publications.waset.org/abstracts/search?q=PBAT" title=" PBAT"> PBAT</a> </p> <a href="https://publications.waset.org/abstracts/179141/polyhedral-oligomeric-silsesquioxane-in-poly-lactic-acid-and-poly-butylene-adipate-co-terephthalate-blend" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179141.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">53</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">1191</span> A Combined CFD Simulation of Plateau Borders including Films and Transitional Areas of Liquid Foams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolhamid%20Anazadehsayed">Abdolhamid Anazadehsayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Naser"> Jamal Naser</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An integrated computational fluid dynamics model is developed for a combined simulation of Plateau borders, films, and transitional areas between the film and the Plateau borders to reduce the simplifications and shortcomings of available models for foam drainage in micro-scale. Additionally, the counter-flow related to the Marangoni effect in the transitional area is investigated. The results of this combined model show the contribution of the films, the exterior Plateau borders, and Marangoni flow in the drainage process more accurately since the inter-influence of foam's elements is included in this study. The exterior Plateau borders flow rate can be four times larger than the interior ones. The exterior bubbles can be more prominent in the drainage process in cases where the number of the exterior Plateau borders increases due to the geometry of container. The ratio of the Marangoni counter-flow to the Plateau border flow increases drastically with an increase in the mobility of air-liquid interface. However, the exterior bubbles follow the same trend with much less intensity since typically, the flow is less dependent on the interface of air-liquid in the exterior bubbles. Moreover, the Marangoni counter-flow in a near-wall transition area is less important than an internal one. The influence of air-liquid interface mobility on the average velocity of interior foams is attained with more accuracy with more realistic boundary condition. Then it has been compared with other numerical and analytical results. The contribution of films in the drainage is significant for the mobile foams as the velocity of flow in the film has the same order of magnitude as the velocity in the Plateau border. Nevertheless, for foams with rigid interfaces, film's contribution in foam drainage is insignificant, particularly for the films near the wall of the container. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foam" title="foam">foam</a>, <a href="https://publications.waset.org/abstracts/search?q=plateau%20border" title=" plateau border"> plateau border</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=Marangoni" title=" Marangoni"> Marangoni</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=bubble" title=" bubble"> bubble</a> </p> <a href="https://publications.waset.org/abstracts/64152/a-combined-cfd-simulation-of-plateau-borders-including-films-and-transitional-areas-of-liquid-foams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64152.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">345</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">1190</span> The Effects of Urbanization on Peri-Urban Livelihood in Ghana: A Case of Kumasi Peri-Urban Communities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Kwaku%20Oppong">Charles Kwaku Oppong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research linked urban expansion resulting from urbanization with changing morphology processes happening in peri-urban communities. Two villages of Kumasi City peri-urban were used as a case study. Appropriate analytical framework and methodology (literature review and empirical evidence) were employed to ensure that all pertinent issues of peri-urban interface are brought to light. It was discovered from the study that since peri-urban livelihood is linked with assets base; it has been found that stock of asset, as well as transformation processes, were major factors in the shaping of livelihoods strategies. For that reason, success or failure of household livelihoods was seen to relate to the kind of livelihood strategy employed. With efforts to mitigate for livelihoods failure due to peri-urban development, households' recourse to remittances, land disposal, and other means as an alternative livelihood approach.

The concentration change of oxygenated hemoglobin and de-oxygenated hemoglobin during particular cognitive activity is the basis for this neuro-imaging modality. Two wavelengths of near-infrared light can be used with modified Beer-Lambert law to explain the indirect status of neuronal activity inside brain. The temporal resolution of fNIRS is very good for real-time brain computer-interface applications. The portability, low cost and an acceptable temporal resolution of fNIRS put it on a better position in neuro-imaging modalities. In this study, an optimization model for impulse response function has been used to estimate/predict initial dip using fNIRS data. In addition, the activity strength parameter related to motor based cognitive task has been analyzed. We found an initial dip that remains around 200-300 millisecond and better localize neural activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fNIRS" title="fNIRS">fNIRS</a>, <a href="https://publications.waset.org/abstracts/search?q=brain-computer%20interface" title=" brain-computer interface"> brain-computer interface</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20algorithm" title=" optimization algorithm"> optimization algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptive%20signal%20processing" title=" adaptive signal processing"> adaptive signal processing</a> </p> <a href="https://publications.waset.org/abstracts/84942/initial-dip-an-early-indicator-of-neural-activity-in-functional-near-infrared-spectroscopy-waveform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84942.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">1188</span> RS Based SCADA System for Longer Distance Powered Devices</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harkishen%20Singh">Harkishen Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gavin%20Mangeni"> Gavin Mangeni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This project aims at building an efficient and automatic power monitoring SCADA system, which is capable of monitoring the electrical parameters of high voltage powered devices in real time for example RMS voltage and current, frequency, energy consumed, power factor etc. The system uses RS-485 serial communication interface to transfer data over longer distances.

Model tests were conducted to obtain the failure mode of the wall, and shear tests on two-layers and five-layers of soil bags were designed to investigate the mechanical characteristics of the interface of soil bags. The test results show that the slip surface in the soil bags-constructed retaining wall is ladder-like due to the inter-layer insertion of soil bags, and the wall above the ladder-like surface undergoes a rigid body translation. The insertion strengthens the shear strength of two-layer staggered-stacked soil bags. Meanwhile, it affects the shape of the slip surface of the five-layer staggered-stacked soil bags.

Commonly the steel body is produced by machining, thermal spraying a bonding layer and hardfacing of Ni-based matrix reinforced with fused eutectic tungsten carbide (WC/W2C). The matrix body bit is manufactured by infiltrating tungsten carbide particles, with a Copper binary or ternary alloy. By erosion-corrosion mechanisms, the PDC drill bits matrix undergoes severe damage, occurring particularly around the PDC inserts and near injection nozzles. In this study, we investigated the possibility to repair the damaged matrix regions by hardfacing technic. Ni-based hardfacing alloy reinforced with fused eutectic tungsten carbide is deposited on infiltrated WC-W-Ni substrate by oxyacetylene welding (OAW). The microstructure at the hardfacing / matrix interface is characterized by SEM- EDS, XRD and micro hardness Hv0.1. The hardfacing conditions greatly affect the dilution phenomenon and the distribution of carbides at the interface, without formation of transition zone. During OAW welding deposition, interdiffusion of atoms occurs: Cu and Sn diffuse from infiltrated matrix substrate into hardfacing and simultaneously Cr and Si alloy elements from hardfacing diffuse towards the substrate. The dilution zone consists of a nickel-rich phase with a heterogeneous distribution of eutectic spherical (Ni-based hardfacing alloy) and irregular (matrix) WC/W2C carbides and a secondary phase rich in Cr-W-Si. Hardfacing conditions cause the dissolution of banding around both spherical and irregular carbides. The micro-hardness of interface is signiﬁcantly improved by the presence of secondary phase in the inter-dendritic structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dilution" title="dilution">dilution</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolution" title=" dissolution"> dissolution</a>, <a href="https://publications.waset.org/abstracts/search?q=hardfacing" title=" hardfacing"> hardfacing</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltrated%20matrix" title=" infiltrated matrix"> infiltrated matrix</a>, <a href="https://publications.waset.org/abstracts/search?q=PDC%20drill%20bits" title=" PDC drill bits"> PDC drill bits</a> </p> <a href="https://publications.waset.org/abstracts/49707/ni-based-hardfacing-alloy-reinforced-with-fused-eutectic-tungsten-carbide-deposited-on-infiltrated-wc-w-ni-substrate-by-oxyacetylene-welding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49707.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">341</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">1185</span> Background Check System for Turkish IT Companies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arzu%20Baloglu">Arzu Baloglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ugur%20Kaplancali"> Ugur Kaplancali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on Background Check Systems and Pre-Employment Screening.

The database of the site will contain all the information about the employees and employers which are registered in the system so the employers can make a search based on their searching criteria to find the suitable employee for the job. The web site also has a comments and points system. The current employer can make comments to his/her employees and can also give them points. The comments will be shown on employee’s profile, so; when an employer searches for an employee he/she can check the points and comments of the employee to see whether he or she is capable of the job or not. The employers can also follow some employees if they desire. This paper has been designed and implemented with using ASP.NET, C# and JavaScript. The outputs have a user friendly interface.

However, the design of educational material user interfaces for mobile devices is beset by many unresolved research issues such as those arising from emphasising the information concepts then mapping this information to appropriate media (modelling information then mapping media effectively). This report describes a multimedia user interface design method for mobile learning. The method covers specification of user requirements and information architecture, media selection to represent the information content, design for directing attention to important information, and interaction design to enhance user engagement based on Human-Computer Interaction design strategies (HCI). The method will be evaluated by three different case studies to prove the method is suitable for application to different areas / applications, these are; an application to teach about major computer networking concepts, an application to deliver a history-based topic; (after these case studies have been completed, the method will be revised to remove deficiencies and then used to develop a third case study), an application to teach mathematical principles. At this point, the method will again be revised into its final format. A usability evaluation will be carried out to measure the usefulness and effectiveness of the method. The investigation will combine qualitative and quantitative methods, including interviews and questionnaires for data collection and three case studies for validating the MDMLM method. The researcher has successfully produced the method at this point which is now under validation and testing procedures. From this point forward in the report, the researcher will refer to the method using the MDMLM abbreviation which means Multimedia Design Mobile Learning Method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human-computer%20interaction" title="human-computer interaction">human-computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20design" title=" interface design"> interface design</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20learning" title=" mobile learning"> mobile learning</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a> </p> <a href="https://publications.waset.org/abstracts/58612/a-method-for-multimedia-user-interface-design-for-mobile-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58612.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">246</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1183</span> An Innovative Green Cooling Approach Using Peltier Chip in Milling Operation for Surface Roughness Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Anayet%20U.%20Patwari">Md.

During any machining operation, high temperatures are generated at the tool-chip interface impairing surface quality and dimensional accuracy of products. Cutting fluids are generally applied during machining to reduce temperature at the tool-chip interface. However, usages of cutting fluids give rise to problems such as waste disposal, pollution, high cost, and human health hazard. Researchers, now-a-days, are opting towards dry machining and other cooling techniques to minimize use of coolants during machining while keeping surface roughness of products within desirable limits. In this paper, a concept of using peltier cooling effects during aluminium milling operation has been presented and adopted with an aim to improve surface roughness of the machined surface. Experimental evidence shows that peltier cooling effect provides better surface roughness of the machined surface compared to dry machining. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium" title="aluminium">aluminium</a>, <a href="https://publications.waset.org/abstracts/search?q=milling%20operation" title=" milling operation"> milling operation</a>, <a href="https://publications.waset.org/abstracts/search?q=peltier%20cooling%20effect" title=" peltier cooling effect"> peltier cooling effect</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a> </p> <a href="https://publications.waset.org/abstracts/67712/an-innovative-green-cooling-approach-using-peltier-chip-in-milling-operation-for-surface-roughness-improvement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67712.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">337</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">1182</span> Simulation of Binary Nitride Inclusions Effect on Tensile Properties of Steel </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Dalirbod">Ali Dalirbod</a>, <a href="https://publications.waset.org/abstracts/search?q=Peyman%20Ahmadian"> Peyman Ahmadian </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inclusions are unavoidable part of all steels. Non-metallic inclusions have significant effects on mechanical properties of steel. The effects of inclusion on stress concentration around the matrix/inclusion have been extensively studied. The results relating to single inclusion behavior, describe properly the behavior of stress but not the elongation drop. The raised stress in inclusion/matrix results in crack initiation. The influence of binary inclusions on stress concentration around matrix is a major aim of this work which is representative of the simple pattern distribution of non-metallic inclusions. Stress concentration around inclusions in this case depends on parameters like distance between two inclusions (d), angle between centrally linking line of two inclusions, load axis (φ), and rotational angle of inclusion (θ). FEM analysis was applied to investigate the highest and lowest ductility versus varying parameters above. The simulation results show that there is a critical distance between two cubic inclusions in which bigger than the threshold, the stress, and strain field in matrix/inclusions interface converts into individual fields around each inclusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitride%20inclusion" title="nitride inclusion">nitride inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20properties" title=" tensile properties"> tensile properties</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion-matrix%20interface" title=" inclusion-matrix interface"> inclusion-matrix interface</a> </p> <a href="https://publications.waset.org/abstracts/33985/simulation-of-binary-nitride-inclusions-effect-on-tensile-properties-of-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33985.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">317</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">1181</span> Project Paulina: A Human-Machine Interface for Individuals with Limited Mobility and Conclusions from Research and Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radoslaw%20Nagay">Radoslaw Nagay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Paulina Project aims to address the challenges faced by immobilized individuals, such as those with multiple sclerosis, muscle dystrophy, or spinal cord injuries, by developing a flexible hardware and software solution. This paper presents the research and development efforts of our team, which commenced in 2019 and is now in its final stage. Recognizing the diverse needs and limitations of individuals with limited mobility, we conducted in-depth testing with a group of 30 participants. The insights gained from these tests led to the complete redesign of the system. Our presentation covers the initial project ideas, observations from in-situ tests, and the newly developed system that is currently under construction. Moreover, in response to the financial constraints faced by many disabled individuals, we propose an affordable business model for the future commercialization of our invention. Through the Paulina Project, we strive to empower immobilized individuals, providing them with greater independence and improved quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UI" title="UI">UI</a>, <a href="https://publications.waset.org/abstracts/search?q=human-machine%20interface" title=" human-machine interface"> human-machine interface</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20inclusion" title=" social inclusion"> social inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20sclerosis" title=" multiple sclerosis"> multiple sclerosis</a>, <a href="https://publications.waset.org/abstracts/search?q=muscular%20dystrophy" title=" muscular dystrophy"> muscular dystrophy</a>, <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20injury" title=" spinal cord injury"> spinal cord injury</a>, <a href="https://publications.waset.org/abstracts/search?q=quadriplegic" title=" quadriplegic"> quadriplegic</a> </p> <a href="https://publications.waset.org/abstracts/168449/project-paulina-a-human-machine-interface-for-individuals-with-limited-mobility-and-conclusions-from-research-and-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168449.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">70</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">1180</span> Design Evaluation Tool for Small Wind Turbine Systems Based on the Simple Load Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihane%20Bouabid">Jihane Bouabid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The urgency to transition towards sustainable energy sources has revealed itself imperative. Today, in the 21st Century, the intellectual society have imposed technological advancements and improvements, and anticipates expeditious outcomes as an integral component of its relentless pursuit of an elevated standard of living. As a part of empowering human development, driving economic growth and meeting social needs, the access to energy services has become a necessity. As a part of these improvements, we are introducing the project "Mywindturbine" - an interactive web user interface for design and analysis in the field of wind energy, with a particular adherence to the IEC (International Electrotechnical Commission) standard 61400-2 "Wind turbines – Part 2: Design requirements for small wind turbines". Wind turbines play a pivotal role in Morocco's renewable energy strategy, leveraging the nation's abundant wind resources. The IEC 61400-2 standard ensures the safety and design integrity of small wind turbines deployed in Morocco, providing guidelines for performance and safety protocols. The conformity with this standard ensures turbine reliability, facilitates standards alignment, and accelerates the integration of wind energy into Morocco's energy landscape. The aim of the GUI (Graphical User Interface) for engineers and professionals from the field of wind energy systems who would like to design a small wind turbine system following the safety requirements of the international standards IEC 61400-2. The interface provides an easy way to analyze the structure of the turbine machine under normal and extreme load conditions based on the specific inputs provided by the user. The platform introduces an overview to sustainability and renewable energy, with a focus on wind turbines. It features a cross-examination of the input parameters provided from the user for the SLM (Simple Load Model) of small wind turbines, and results in an analysis according to the IEC 61400-2 standard. The analysis of the simple load model encompasses calculations for fatigue loads on blades and rotor shaft, yaw error load on blades, etc. for the small wind turbine performance. Through its structured framework and adherence to the IEC standard, "Mywindturbine" aims to empower professionals, engineers, and intellectuals with the knowledge and tools necessary to contribute towards a sustainable energy future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20wind%20turbine" title="small wind turbine">small
