change in their discovery process. Computational models can be used to accelerate experimental steps and control the high cost of experiments. Methods: In this work, to better understand the interaction of anti-cancer drug and the nanocarrier with the cell membrane, we have done molecular dynamics simulation using NAMD. We have chosen paclitaxel for the drug molecule and dipalmitoylphosphatidylcholine (DPPC) as a natural phospholipid nanocarrier. Results: Next, center of mass (COM) between molecules and the van der Waals interaction energy close to the cell membrane has been analyzed. Furthermore, the simulation results of the paclitaxel interaction with the cell membrane and the interaction of DPPC as a nanocarrier loaded by the drug with the cell membrane have been compared. Discussion: Analysis by molecular dynamics (MD) showed that not only the energy between the nanocarrier and the cell membrane is low, but also the center of mass amount decreases in the nanocarrier and the cell membrane system during the interaction; therefore they show significantly better interaction in comparison to the individual drug with the cell membrane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-cancer%20drug" title="anti-cancer drug">anti-cancer drug</a>, <a href="https://publications.waset.org/abstracts/search?q=center%20of%20mass" title=" center of mass"> center of mass</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20energy" title=" interaction energy"> interaction energy</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarrier" title=" nanocarrier"> nanocarrier</a> </p> <a href="https://publications.waset.org/abstracts/73338/understanding-nanocarrier-efficacy-in-drug-delivery-systems-using-molecular-dynamics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73338.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">299</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">5451</span> Molecular Dynamics Studies of Main Factors Affecting Mass Transport Phenomena on Cathode of Polymer Electrolyte Membrane Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingjing%20Huang">Jingjing Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nengwei%20Li"> Nengwei Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Guanghua%20Wei"> Guanghua Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiabin%20You"> Jiabin You</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20Wang"> Chao Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Junliang%20Zhang"> Junliang Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, molecular dynamics (MD) simulation is applied to analyze the mass transport process in the cathode of proton exchange membrane fuel cell (PEMFC), of which all types of molecules situated in the cathode is considered. a reasonable and effective MD simulation process is provided, and models were built and compared using both Materials Studio and LAMMPS. The mass transport is one of the key issues in the study of proton exchange membrane fuel cells (PEMFCs). In this report, molecular dynamics (MD) simulation is applied to analyze the influence of Nafion ionomer distribution and Pt nano-particle size on mass transport process in the cathode. It is indicated by the diffusion coefficients calculation that a larger quantity of Nafion, as well as a higher equivalent weight (EW) value, will hinder the transport of oxygen. In addition, medium-sized Pt nano-particles (1.5~2nm) are more advantageous in terms of proton transport compared with other particle sizes (0.94~2.55nm) when the center-to-center distance between two Pt nano-particles is around 5 nm. Then mass transport channels are found to be formed between the hydrophobic backbone and the hydrophilic side chains of Nafion ionomer according to the radial distribution function (RDF) curves. And the morphology of these channels affected by the Pt size is believed to influence the transport of hydronium ions and, consequently the performance of PEMFC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cathode%20catalytic%20layer" title="cathode catalytic layer">cathode catalytic layer</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20transport" title=" mass transport"> mass transport</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20fuel%20cell" title=" proton exchange membrane fuel cell"> proton exchange membrane fuel cell</a> </p> <a href="https://publications.waset.org/abstracts/160053/molecular-dynamics-studies-of-main-factors-affecting-mass-transport-phenomena-on-cathode-of-polymer-electrolyte-membrane-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160053.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">243</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">5450</span> Composite 'C' Springs for Anti-Seismic Building Suspension: Positioning 'Virtual Center of Pendulation above Gravity Center'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Max%20Sardou">Max Sardou</a>, <a href="https://publications.waset.org/abstracts/search?q=Patricia%20Sardou"> Patricia Sardou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Now that weight saving is mandatory, to author best knowledge composite springs, that we have invented, are best choice for automotive suspensions, against steel. So, we have created a Joint Ventures called S.ARA, in order to mass produce composite coils springs. Start of Production of composite coils springs was in 2014 for AUDI. As we have demonstrated, on the road, that composite springs are not a sweet dream. The present paper describes all the benefits of ‘C’ springs and ‘S’ springs for high performance vehicles suspension, for rocket stage separation, and for satellite injection into orbit. Developing rocket stage separation, we have developed for CNES (Centre National d’Etudes Spatiales) the following concept. If we call ‘line of action’ a line going from one end of a spring to the other. Our concept is to use for instance two springs inclined. In such a way that their line of action cross together and create at this crossing point a virtual center well above the springs. This virtual center, is pulling from above the top stage and is offering a guidance, perfectly stable and straight. About buildings, our solution is to transfer this rocket technology, creating a ‘virtual center’ of pendulation positioned above the building center of gravity. This is achieved by using tilted composite springs benches oriented in such a way that their line of action converges creating the ‘virtual center’. Thanks to the ‘virtual center’ position, the building behaves as a pendulum, hanged from above. When earthquake happen then the building will oscillate around its ‘virtual center’ and will go back safely to equilibrium after the tremor. ‘C’ springs, offering anti-rust, anti-settlement, fail-safe suspension, plus virtual center solution is the must for long-lasting, perfect protection of buildings against earthquakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20center%20of%20tilt" title="virtual center of tilt">virtual center of tilt</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20springs" title=" composite springs"> composite springs</a>, <a href="https://publications.waset.org/abstracts/search?q=fail%20safe%20springs" title=" fail safe springs"> fail safe springs</a>, <a href="https://publications.waset.org/abstracts/search?q=antiseismic%20suspention" title=" antiseismic suspention"> antiseismic suspention</a> </p> <a href="https://publications.waset.org/abstracts/92742/composite-c-springs-for-anti-seismic-building-suspension-positioning-virtual-center-of-pendulation-above-gravity-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92742.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">244</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">5449</span> Vibration of Gamma Graphyne with an Attached Mass</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Win-Jin%20Chang">Win-Jin Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Haw-Long%20Lee"> Haw-Long Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Ching%20Yang"> Yu-Ching Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Atomic finite element simulation is applied to investigate the vibration frequency of a single-layer gamma graphyne with an attached mass for the CCCC, SSSS, CFCF, SFSF boundary conditions using the commercial code ANSYS. The fundamental frequencies of the graphyne sheet are compared with the results of the previous study. The results of the comparison are very good in all considered cases. The attached mass causes a shift in the resonant frequency of the graphyne. The frequencies of the single-layer gamma graphyne with an attached mass for different boundary conditions are obtained, and the order based on the boundary condition is CCCC >SSSS > CFCF> SFSF. The highest frequency shift is obtained when the attached mass is located at the center of the graphyne sheet.

Leaning a bicycle driving is long time process and goes through building knowledge base for parameter decision making while balancing robots. In order to create this machine learning phase with embedded system the proposed system is designed. The system proposed aims to construct a bicycle automaton, power-driven by an electric motor, which could balance by itself and move along a specific path. This path could be wavy with bumps and varying widths. The key aim was to construct a cycle which self-balances itself by controlling its handle. In order to take a turn, the mass was transferred to the center. In order to maintain the stability, the bicycle bot automatically turned the handle and a turn. Some problems were faced by the team which were Speed, Steering mechanism through mass- distribution (leaning), Center of mass location and gyroscopic effect of its wheel. The idea proposed have potential applications in automation of transportation system and is most efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gyroscope-flywheel" title="gyroscope-flywheel">gyroscope-flywheel</a>, <a href="https://publications.waset.org/abstracts/search?q=accelerometer" title=" accelerometer"> accelerometer</a>, <a href="https://publications.waset.org/abstracts/search?q=servomotor-controller" title=" servomotor-controller"> servomotor-controller</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20stability%20concept" title=" self stability concept"> self stability concept</a> </p> <a href="https://publications.waset.org/abstracts/25084/design-of-self-balancing-bicycle-using-object-state-detection-in-co-ordinate-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25084.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">278</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">5447</span> Experimental Investigation of Natural Frequency and Forced Vibration of Euler-Bernoulli Beam under Displacement of Concentrated Mass and Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aref%20Aasi">Aref Aasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadegh%20Mehdi%20Aghaei"> Sadegh Mehdi Aghaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Balaji%20Panchapakesan"> Balaji Panchapakesan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work aims to evaluate the free and forced vibration of a beam with two end joints subjected to a concentrated moving mass and a load using the Euler-Bernoulli method. The natural frequency is calculated for different locations of the concentrated mass and load on the beam. The analytical results are verified by the experimental data. The variations of natural frequency as a function of the location of the mass, the effect of the forced frequency on the vibrational amplitude, and the displacement amplitude versus time are investigated. It is discovered that as the concentrated mass moves toward the center of the beam, the natural frequency of the beam and the relative error between experimental and analytical data decreases. There is a close resemblance between analytical data and experimental observations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Euler-Bernoulli%20beam" title="Euler-Bernoulli beam">Euler-Bernoulli beam</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title=" natural frequency"> natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20vibration" title=" forced vibration"> forced vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20setup" title=" experimental setup"> experimental setup</a> </p> <a href="https://publications.waset.org/abstracts/144338/experimental-investigation-of-natural-frequency-and-forced-vibration-of-euler-bernoulli-beam-under-displacement-of-concentrated-mass-and-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144338.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">274</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">5446</span> Study of Gait Stability Evaluation Technique Based on Linear Inverted Pendulum Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kang%20Sungjae">Kang Sungjae</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research proposes a gait stability evaluation technique based on the linear inverted pendulum model and moving support foot Zero Moment Point. With this, an improvement towards the gait analysis of the orthosis walk is validated. The application of Lagrangian mechanics approximation to the solutions of the dynamics equations for the linear inverted pendulum does not only simplify the solution, but it provides a smooth Zero Moment Point for the double feet support phase. The Zero Moment Point gait analysis techniques mentioned above validates reference trajectories for the center of mass of the gait orthosis, the timing of the steps and landing position references for the swing feet. The stability evaluation technique are tested with a 6 DOF powered gait orthosis.

This paper describes the full scale measurement to explain the tuned mass damper effects of stationary people on structural damping of footbridge with center span length of 33 m. A human body can be represented by a lumped system consisting of masses, springs, and dashpots. Complex eigenvalue calculation is also conducted by using ISO5982:1981 human model (two degree of freedom system). Based on experimental and analytical results for the footbridge with the stationary people in the standing position, it is demonstrated that stationary people behave as a tuned mass damper and that ISO5982:1981 human model can explain the structural damping characteristics measured in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20interaction" title="dynamic interaction">dynamic interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=footbridge" title=" footbridge"> footbridge</a>, <a href="https://publications.waset.org/abstracts/search?q=stationary%20people" title=" stationary people"> stationary people</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20damping" title=" structural damping"> structural damping</a> </p> <a href="https://publications.waset.org/abstracts/47682/tuned-mass-damper-effects-of-stationary-people-on-structural-damping-of-footbridge-due-to-dynamic-interaction-in-vertical-motion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47682.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">274</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">5442</span> Fault Tree Analysis (FTA) of CNC Turning Center</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20B.%20Patil">R.

However, as the breakdown of a single CNC turning center may result in the production of an entire plant being halted. For this reason, operations and preventive maintenance have to be minimized to ensure availability of the system. Indeed, improving the availability of the CNC turning center as a whole, objectively leads to a substantial reduction in production loss, operating, maintenance and support cost. In this paper, fault tree analysis (FTA) method is used for reliability analysis of CNC turning center. The major faults associated with the system and the causes for the faults are presented graphically. Boolean algebra is used for evaluating fault tree (FT) diagram and for deriving governing reliability model for CNC turning center. Failure data over a period of six years has been collected and used for evaluating the model. Qualitative and quantitative analysis is also carried out to identify critical sub-systems and components of CNC turning center. It is found that, at the end of the warranty period (one year), the reliability of the CNC turning center as a whole is around 0.61628. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20tree%20analysis%20%28FTA%29" title="fault tree analysis (FTA)">fault tree analysis (FTA)</a>, <a href="https://publications.waset.org/abstracts/search?q=reliability%20analysis" title=" reliability analysis"> reliability analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20assessment" title=" risk assessment"> risk assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=hazard%20analysis" title=" hazard analysis"> hazard analysis</a> </p> <a href="https://publications.waset.org/abstracts/41777/fault-tree-analysis-fta-of-cnc-turning-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41777.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">414</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">5441</span> Crater Pattern on the Moon and Origin of the Moon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xuguang%20Leng">Xuguang Leng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The crater pattern on the Moon indicates the Moon was captured by Earth in the more recent years, disproves the theory that the Moon was born as a satellite to the Earth. The Moon was tidal locked since it became the satellite of the Earth. Moon’s near side is shielded by Earth from asteroid/comet collisions, with the center of the near side most protected. Yet the crater pattern on the Moon is fairly random, with no distinguishable empty spot/strip, no distinguishable difference near side vs. far side. Were the Moon born as Earth’s satellite, there would be a clear crater free spot, or strip should the tial lock shifts over time, on the near side; and far more craters on the far side. The nonexistence of even a vague crater free spot on the near side of the Moon indicates the capture was a more recent event. Given Earth’s much larger mass and sphere size over the Moon, Earth should have collided with asteroids and comets in much higher frequency, resulting in significant mass gain over the lifespan. Earth’s larger mass and magnetic field are better at retaining water and gas from solar wind’s stripping effect, thus accelerating the mass gain. A dwarf planet Moon can be pulled closer and closer to the Earth over time as Earth’s gravity grows stronger, eventually being captured as a satellite. Given enough time, it is possible Earth’s mass would be large enough to cause the Moon to collide with Earth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moon" title="moon">moon</a>, <a href="https://publications.waset.org/abstracts/search?q=origin" title=" origin"> origin</a>, <a href="https://publications.waset.org/abstracts/search?q=crater" title=" crater"> crater</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern" title=" pattern"> pattern</a> </p> <a href="https://publications.waset.org/abstracts/149225/crater-pattern-on-the-moon-and-origin-of-the-moon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149225.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5440</span> The Reach of Shopping Center Layout Form on Subway Based on Kernel Density Estimate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen%20Liu">Wen Liu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the rapid progress of modern cities, the railway construction must be developing quickly in China.

The behaviour of a building during an earthquake depends on several factors such as stiffness, adequate lateral strength, ductility, and configurations. The experience from the performance of buildings during past earthquakes has shown that the buildings with regular geometry, uniformly distributed mass and stiffness in plan as well as in elevation suffer much less damage compared to irregular configurations. The three centers namely- centre of mass, centre of strength, centre of stiffness are the torsional parameters which contribute to the strength of the building in case of an earthquake. Inertial forces and resistive forces in a structural system act through the center of mass and center of rigidity respectively which together oppose the forces that are produced during seismic excitation. So these centers of a structural system should be positioned where the structural system is the strongest so that the effects produced due to the earthquake may have a minimal effect on the structure. In this paper, the effects of variation of strength eccentricity and stiffness eccentricity in reducing the torsional responses of the asymmetrical buildings by using pushover analysis are studied. The maximum reduction of base torsion was observed in the case of minimum strength eccentricity, and the least reduction was observed in the case of minimum stiffness eccentricity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=strength%20eccentricity" title="strength eccentricity">strength eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness%20eccentricity" title=" stiffness eccentricity"> stiffness eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=asymmetric%20structure" title=" asymmetric structure"> asymmetric structure</a>, <a href="https://publications.waset.org/abstracts/search?q=base%20torsion" title=" base torsion"> base torsion</a>, <a href="https://publications.waset.org/abstracts/search?q=push%20over%20analysis" title=" push over analysis"> push over analysis</a> </p> <a href="https://publications.waset.org/abstracts/63017/effects-of-variation-of-centers-in-the-torsional-analysis-of-asymmetrical-buildings-by-performing-non-linear-static-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63017.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">294</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">5438</span> Positive Politeness in Writing Centre Consultations with an Emphasis on Praise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Avasha%20Rambiritch">Avasha Rambiritch</a>, <a href="https://publications.waset.org/abstracts/search?q=Adelia%20Carstens"> Adelia Carstens</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In especially the context of a writing center, learning takes place during, and as part of, the conversations between the writing center tutor and the student. This interaction or dialogue is an integral part of writing center research and is the focus of this largely qualitative study, employing a politeness lens. While there is some research on positive politeness strategies employed by writing center tutors, there is very little research on specifically praising as a positive politeness strategy. This study attempts to fill this gap by analyzing a corpus of 10 video-recorded consultations to determine how tutors in a writing center utilize the positive politeness strategy of praise. Findings indicate that while tutors exploit a range of politeness strategies, praise is used more often than any other strategy. The research indicates that praise as a politeness strategy is utilized significantly more when commenting on higher-order concerns, as in line with the writing center literature. The benefits of this study include insights into how such analyses can be used to better prepare and equip the tutors (usually postgraduate students appointed as part-time tutors in the writing center) for the work they do on a daily basis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=writing%20center" title="writing center">writing center</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20writing" title=" academic writing"> academic writing</a>, <a href="https://publications.waset.org/abstracts/search?q=positive%20politeness" title=" positive politeness"> positive politeness</a>, <a href="https://publications.waset.org/abstracts/search?q=tutor" title=" tutor"> tutor</a> </p> <a href="https://publications.waset.org/abstracts/135646/positive-politeness-in-writing-centre-consultations-with-an-emphasis-on-praise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135646.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">215</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">5437</span> Schrödinger Equation with Position-Dependent Mass: Staggered Mass Distributions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20J.%20Pe%C3%B1a">J.

This work focused on two important interaction parameters between molecules in terms of center of mass (COM) and van der Waals interaction energy. Furthermore, we compared the simulation results of the PTX interaction with the cell membrane and the interaction of DPPC as a nanocarrier loaded by the drug with the cell membrane. The molecular dynamic analysis resulted in low energy between the nanocarrier and the cell membrane as well as significant decrease of COM amount in the nanocarrier and the cell membrane system during the interaction. Thus, the drug vehicle showed notably better interaction with the cell membrane in compared to free drug interaction with the cell membrane. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-cancer%20drug" title="anti-cancer drug">anti-cancer drug</a>, <a href="https://publications.waset.org/abstracts/search?q=center%20of%20mass" title=" center of mass"> center of mass</a>, <a href="https://publications.waset.org/abstracts/search?q=interaction%20energy" title=" interaction energy"> interaction energy</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics%20simulation" title=" molecular dynamics simulation"> molecular dynamics simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocarrier" title=" nanocarrier"> nanocarrier</a> </p> <a href="https://publications.waset.org/abstracts/73548/assessment-of-drug-delivery-systems-from-molecular-dynamic-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73548.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">5435</span> Adjustment of the Whole-Body Center of Mass during Trunk-Flexed Walking across Uneven Ground</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soran%20Aminiaghdam">Soran Aminiaghdam</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Rode"> Christian Rode</a>, <a href="https://publications.waset.org/abstracts/search?q=Reinhard%20Blickhan"> Reinhard Blickhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Astrid%20Zech"> Astrid Zech</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite considerable studies on the impact of imposed trunk posture on human walking, less is known about such locomotion while negotiating changes in ground level. The aim of this study was to investigate the behavior of the VBCOM in response to a two-fold expected perturbation, namely alterations in body posture and in ground level. To this end, the kinematic data and ground reaction forces of twelve able participants were collected. We analyzed the vertical position of the body center of mass (VBCOM) from the ground determined by the body segmental analysis method relative to the laboratory coordinate system at touchdown and toe-off instants during walking across uneven ground — characterized by perturbation contact (a 10-cm visible drop) and pre- and post-perturbation contacts — in comparison to unperturbed level contact while maintaining three postures (regular erect, ~30° and ~50° of trunk flexion from the vertical). The VBCOM was normalized to the distance between the greater trochanter marker and the lateral malleoli marker at the instant of TD. Moreover, we calculated the backward rotation during step-down as the difference of the maximum of the trunk angle in the pre-perturbation contact and the minimal trunk angle in the perturbation contact. Two-way repeated measures ANOVAs revealed contact-specific effects of posture on the VBCOM at touchdown (F = 5.96, p = 0.00). As indicated by the analysis of simple main effects, during unperturbed level and pre-perturbation contacts, no between-posture differences for the VBCOM at touchdown were found. In the perturbation contact, trunk-flexed gaits showed a significant increase of VBCOM as compared to the pre-perturbation contact. In the post-perturbation contact, the VBCOM demonstrated a significant decrease in all gait postures relative to the preceding corresponding contacts with no between-posture differences. Main effects of posture revealed that the VBCOM at toe-off significantly decreased in trunk-flexed gaits relative to the regular erect gait. For the main effect of contact, the VBCOM at toe-off demonstrated changes across perturbation and post-perturbation contacts as compared to the unperturbed level contact. Furthermore, participants exhibited a backward trunk rotation during step-down possibly to control the angular momentum of their whole body. A more pronounced backward trunk rotation (2- to 3-fold compared with level contacts) in trunk-flexed walking contributed to the observed elevated VBCOM during the step-down which may have facilitated drop negotiation. These results may shed light on the interaction between posture and locomotion in able gait, and specifically on the behavior of the body center of mass during perturbed locomotion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=center%20of%20mass" title="center of mass">center of mass</a>, <a href="https://publications.waset.org/abstracts/search?q=perturbation" title=" perturbation"> perturbation</a>, <a href="https://publications.waset.org/abstracts/search?q=posture" title=" posture"> posture</a>, <a href="https://publications.waset.org/abstracts/search?q=uneven%20ground" title=" uneven ground"> uneven ground</a>, <a href="https://publications.waset.org/abstracts/search?q=walking" title=" walking"> walking</a> </p> <a href="https://publications.waset.org/abstracts/86029/adjustment-of-the-whole-body-center-of-mass-during-trunk-flexed-walking-across-uneven-ground" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86029.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">181</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">5434</span> The Role of Public Education in Increasing Public Awareness through Mass Media with Emphasis on Newspapers and TV: Coping with Possible Earthquake in Tehran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Naser%20Charkhsaz">Naser Charkhsaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Sadat%20Mousavi"> Ashraf Sadat Mousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Navvab%20Shamspour"> Navvab Shamspour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to evaluate the role of state education in increasing public awareness through mass media (with emphasis on newspapers and TV) coping with possible earthquake in Tehran.

The results showed that warnings related to the Tehran earthquake affected people in the pre<span dir="RTL">-</span>contemplation stage, while public education through mass media did not promote public awareness about prevention, preparedness and rehabilitation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=media" title="media">media</a>, <a href="https://publications.waset.org/abstracts/search?q=disaster" title=" disaster"> disaster</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=Iranian%20Red%20Crescent%20society" title=" Iranian Red Crescent society"> Iranian Red Crescent society</a> </p> <a href="https://publications.waset.org/abstracts/52975/the-role-of-public-education-in-increasing-public-awareness-through-mass-media-with-emphasis-on-newspapers-and-tv-coping-with-possible-earthquake-in-tehran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52975.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">318</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">5433</span> Research on Hangzhou Commercial Center System Based on Point of Interest Data</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chen%20Wang">Chen Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiuxiao%20Chen"> Qiuxiao Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the advent of the information age and the era of big data, urban planning research is no longer satisfied with the analysis and application of traditional data. Because of the limitations of traditional urban commercial center system research, big data provides new opportunities for urban research. Therefore, based on the quantitative evaluation method of big data, the commercial center system of the main city of Hangzhou is analyzed and evaluated, and the scale and hierarchical structure characteristics of the urban commercial center system are studied. In order to make up for the shortcomings of the existing POI extraction method, it proposes a POI extraction method based on adaptive adjustment of search window, which can accurately and efficiently extract the POI data of commercial business in the main city of Hangzhou. Through the visualization and nuclear density analysis of the extracted Point of Interest (POI) data, the current situation of the commercial center system in the main city of Hangzhou is evaluated. Then it compares with the commercial center system structure of 'Hangzhou City Master Plan (2001-2020)', analyzes the problems existing in the planned urban commercial center system, and provides corresponding suggestions and optimization strategy for the optimization of the planning of Hangzhou commercial center system. Then get the following conclusions: The status quo of the commercial center system in the main city of Hangzhou presents a first-level main center, a two-level main center, three third-level sub-centers, and multiple community-level business centers. Generally speaking, the construction of the main center in the commercial center system is basically up to standard, and there is still a big gap in the construction of the sub-center and the regional-level commercial center, further construction is needed. Therefore, it proposes an optimized hierarchical functional system, organizes commercial centers in an orderly manner; strengthens the central radiation to drive surrounding areas; implements the construction guidance of the center, effectively promotes the development of group formation and further improves the commercial center system structure of the main city of Hangzhou. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20center%20system" title="business center system">business center system</a>, <a href="https://publications.waset.org/abstracts/search?q=business%20format" title=" business format"> business format</a>, <a href="https://publications.waset.org/abstracts/search?q=main%20city%20of%20Hangzhou" title=" main city of Hangzhou"> main city of Hangzhou</a>, <a href="https://publications.waset.org/abstracts/search?q=POI%20extraction%20method" title=" POI extraction method "> POI extraction method </a> </p> <a href="https://publications.waset.org/abstracts/103080/research-on-hangzhou-commercial-center-system-based-on-point-of-interest-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103080.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">5432</span> The Association Between Different Body Mass Index Levels And Midterm Surgical Revascularization Outcomes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Masoud%20Kabir">Farzad Masoud Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Bagheri"> Jamshid Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Khosro%20Barkhordari"> Khosro Barkhordari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This historical cohort study included 17,751 patients patients who underwent isolated CABG at our center between 2007 and 2016.

These are communication exchanges that are packed with psychological, cultural and social dimensions that affect the specific experience of the parties. The increasing development of information and communication technology over the past decades brought about important advantages and corresponding disadvantages in the process of communicational transactions in call center industry. It has been established that the technology is so powerful that it strongly affects, among others, call center business. In the present study, the author explores the interplay between the technology being utilized by the industry and the cultural orientations of both the call center agents and their customers in the process of communication exchanges. Specifically, the paper seeks to (1) describe the interplay between culture and technology in inbound call center industry as it affects the communication exchange of the agents and customers; (2) understand the nature and the dynamics of the call center industry as regards the cultural dimensions of Hofstede; and (3) come up with a simple study where the cross-cultural aspect of the call center industry could be highlighted and could provide necessary knowledge to the stakeholders. Cognizant of the complexity of the topic, the researchers employed Hofstede's cultural dimensions. Likewise, another theory that was used in this study is the Computer Mediated Communication Theory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=call%20center%20industry" title="call center industry">call center industry</a>, <a href="https://publications.waset.org/abstracts/search?q=culture" title=" culture"> culture</a>, <a href="https://publications.waset.org/abstracts/search?q=Hofstede" title=" Hofstede"> Hofstede</a>, <a href="https://publications.waset.org/abstracts/search?q=CMT" title=" CMT"> CMT</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/47252/the-interplay-between-technology-and-culture-in-inbound-call-center-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47252.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">352</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">5430</span> Temperature Distribution Enhancement in a Conical Diffuser Fitted with Helical Screw-Tape with and without Center-Rod</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehan%20Sabah%20Shukri">Ehan Sabah Shukri</a>, <a href="https://publications.waset.org/abstracts/search?q=Wirachman%20Wisnoe"> Wirachman Wisnoe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Temperature distribution investigation in a conical diffuser fitted with helical screw-tape with and without center-rod is studied numerically.

Here, we consider systems in which a square object is submerged in a channel of fluid and moves parallel to the wall. The corresponding added mass at a given distance from the wall d and for the object size s (which is the side of square object) is calculated via lattice Blotzmann simulation . By changing d and s separately, their effect on the added mass is studied systematically. The simulation results reveal that for the systems in which d > 4s, the distance does not influence the added mass any more. The added mass increases when the object approaches the wall and reaches its maximum value as it moves on the wall (d -- > 0). In this case, the added mass is about 73% larger than which of the case d=4s. In addition, it is observed that the added mass increases by increasing of the object size s and vice versa. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lattice%20Boltzmann%20simulation" title="Lattice Boltzmann simulation ">Lattice Boltzmann simulation </a>, <a href="https://publications.waset.org/abstracts/search?q=added%20mass" title=" added mass"> added mass</a>, <a href="https://publications.waset.org/abstracts/search?q=square" title=" square"> square</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20size" title=" variable size"> variable size</a> </p> <a href="https://publications.waset.org/abstracts/22399/calculation-of-the-added-mass-of-a-submerged-object-with-variable-sizes-at-different-distances-from-the-wall-via-lattice-boltzmann-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22399.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">476</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">5428</span> Solution of Logistics Center Selection Problem Using the Axiomatic Design Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fulya%20Zaral%C4%B1">Fulya Zaralı</a>, <a href="https://publications.waset.org/abstracts/search?q=Harun%20Resit%20Yazgan"> Harun Resit Yazgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Logistics centers represent areas that all national and international logistics and activities related to logistics can be implemented by the various businesses.

The coupling between them is in terms of spacetime forming the universe and things. The birth of things is based on exchange energy between the white and black sides. That is, the transition from the white side to the black side is called wave-matter, where it has a speed faster than light with positive gravity. The transition from the black to the white side has a speed faster than light with negative gravity called a wave-particle. In the part where the speed is equal to light, the particle rest mass is formed. Things can appear to take shape here. Thus, the gravity is zero because it is the center. The gravitational force belongs to the Earth itself because it is in a position that is twisted towards the white hole. Therefore, it is negative. The coupling of black-white holes occurs directly on both sides. The mass is formed at the saturation and will create universes and other things. Therefore, it can be hundreds of thousands of universes on both sides of the B and white holes before reaching the saturation point of multi-universes. This work will use the DJV circuit that the research team made as an entangled or two-level system circuit that has been experimentally demonstrated. Therefore, this principle has the possibility for interpretation. This work explains the emergence of multiple universes and can be applied as a practical guideline for searching for universes in the future. Moreover, the results indicate that the DJV circuit can create the elementary particles according to Feynman's diagram with rest mass conditions, which will be discussed for fission and fusion applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-universes" title="multi-universes">multi-universes</a>, <a href="https://publications.waset.org/abstracts/search?q=feynman%20diagram" title=" feynman diagram"> feynman diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=fission" title=" fission"> fission</a>, <a href="https://publications.waset.org/abstracts/search?q=fusion" title=" fusion"> fusion</a> </p> <a href="https://publications.waset.org/abstracts/176368/multi-universe-existence-based-on-quantum-relativity-using-djv-circuit-experiment-interpretation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176368.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">63</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">5426</span> Electromagnetic Tuned Mass Damper Approach for Regenerative Suspension</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Kopylov">S.

Given the existence of interstellar dust and bright stars, it is nearly impossible to observe its position, about 24,000 light-years away. Due to this uncertainty, humans have often speculated what could exist at a vantage point upon which the entire galaxy spirals and revolves, with wild theories ranging from the presence of dark matter to black holes and wormholes. Data up till now on the same is very limited, and conclusions are to the best of the author's knowledge, as the only method to view the galactic center is through x-ray and infrared imaging, which counter the problems mentioned earlier. This paper examines, first, the existence of a galactic center, then the methods to identify what it might contain, and lastly, possible conclusions along with implications of the findings. Several secondary sources, along with a python tool to analyze x-ray readings were used to identify the true nature of what lies in the center of the galaxy, whether it be a void due to the existence of dark energy or a black hole. Using this roughly 4-part examination, as a result of this study, a plausible definition of the galactic center was formulated, keeping in mind the rather wild theories, data and different ideas proposed by researchers. This paper aims to dissect the theory of a galactic center and identify its nature to help understand what it shows about galaxies and our universe. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=milky%20way" title="milky way">milky way</a>, <a href="https://publications.waset.org/abstracts/search?q=galaxy" title=" galaxy"> galaxy</a>, <a href="https://publications.waset.org/abstracts/search?q=dark%20energy" title=" dark energy"> dark energy</a>, <a href="https://publications.waset.org/abstracts/search?q=stars" title=" stars"> stars</a> </p> <a href="https://publications.waset.org/abstracts/148027/centre-of-the-milky-way-galaxy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148027.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">126</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">5424</span> Investigation of Airship Motion Sensitivity to Geometric Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Han%20Ding">Han Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Xiaoliang"> Wang Xiaoliang</a>, <a href="https://publications.waset.org/abstracts/search?q=Duan%20Dengping"> Duan Dengping</a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the process of airship design, the layout and the geometric shape of the hull and fins are crucial to the motion characteristics of the airship.
