The tie force (TF) method is one of the main design approaches for progressive collapse. As the TF method is a simplified method, further investigations on the reliability of the method is necessary. This study aims to develop an improved TF method to design the cross wall structures for progressive collapse. To this end, the pullout behavior of strands in grout was firstly analyzed; and then, by considering the tie force-slip relationship in the friction stage together with the catenary action mechanism, a comprehensive analytical method was developed. The reliability of this approach is verified by the experimental results of concrete block pullout tests and full scale floor-to-floor joints tests undertaken by Portland Cement Association (PCA). Discrepancies in the tie force between the analytical results and codified specifications have suggested the deficiency of TF method, hence an improved model based on the analytical results has been proposed to address this concern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20wall" title="cross wall">cross wall</a>, <a href="https://publications.waset.org/abstracts/search?q=progressive%20collapse" title=" progressive collapse"> progressive collapse</a>, <a href="https://publications.waset.org/abstracts/search?q=ties%20force%20method" title=" ties force method"> ties force method</a>, <a href="https://publications.waset.org/abstracts/search?q=catenary" title=" catenary"> catenary</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical" title=" analytical"> analytical</a> </p> <a href="https://publications.waset.org/abstracts/1653/an-improved-tie-force-method-for-progressive-collapse-resistance-design-of-precast-concrete-cross-wall-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1653.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20702</span> Capitalizing on Differential Network Ties: Unpacking Individual Creativity from Social Capital Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanyuan%20Wang">Yuanyuan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Hui"> Chun Hui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Drawing on social capital theory, this article discusses how individuals may utilize network ties to come up with creativity. Social capital theory elaborates how network ties enhances individual creativity from three dimensions: structural access, and relational and cognitive mechanisms. We categorize network ties into strong and weak in terms of tie strength. With less structural constraints, weak ties allow diverse and heterogeneous knowledge to prosper, further facilitating individuals to build up connections among diverse even distant ideas. On the other hand, strong ties with the relational mechanism of cooperation and trust may benefit the accumulation of psychological capital, ultimately to motivate and sustain creativity. We suggest that differential ties play different roles for individual creativity: Weak ties deliver informational benefit directly rifling individual creativity from informational resource aspect; strong ties offer solidarity benefits to reinforce psychological capital, which further inspires individual creativity engagement from a psychological viewpoint. Social capital embedded in network ties influence individuals’ informational acquisition, motivation, as well as cognitive ability to be creative. Besides, we also consider the moderating effects constraining the relatedness between network ties and creativity, such as knowledge articulability. We hypothesize that when the extent of knowledge articulability is low, that is, with low knowledge codifiability, and high dependency and ambiguity, weak ties previous serving as knowledge reservoir will not become ineffective on individual creativity. Two-wave survey will be employed in Mainland China to empirically test mentioned propositions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20ties" title="network ties">network ties</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20capital" title=" social capital"> social capital</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20capital" title=" psychological capital"> psychological capital</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20articulability" title=" knowledge articulability"> knowledge articulability</a>, <a href="https://publications.waset.org/abstracts/search?q=individual%20creativity" title=" individual creativity"> individual creativity</a> </p> <a href="https://publications.waset.org/abstracts/26207/capitalizing-on-differential-network-ties-unpacking-individual-creativity-from-social-capital-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26207.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">404</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">20701</span> Assessing India’s Foreign Policy Towards Afghanistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saifurahman%20Fayiz">Saifurahman Fayiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Afghanistan and India have close technical, political, economic, and diplomatic bilateral ties.

The aim of this paper is to empirically prove the effect of social ties (strong and weak tie) as social capital construct on households’ migration decision in the case of developing country (Indonesia). The methodology incorporated indicators of observe variables (four demographic attributes data: income, occupation, education, and family members) and indicators of latent variables (ties to neighbors, ties to community and sense of place) provided by responses to survey questions to aid in estimating the model. Using structural equation model that we employed in Mplus program, the result of our study shows that ties to community positively have a significant impact to the decision of respondents (migrate or not). Besides, education as observed variable directly influences the migration decisions. It seems that higher level of education have impact on migration decision.

The FAT method, also called RIFF method (Filtered Windowed Inverse Resolution), allows to identify the force distribution from local vibration field. In order to only identify the external force applied on a structure, it is necessary to quantify the fluid-structure coupling, especially in naval application, where the fluid is heavy. This method can be decomposed in two parts, the first one consists in identifying the fluid-structure coupling and the second one to introduced it in the FAT method to reconstruct the external force.

To measure the tensile force of PSC girder, several NDT methods were studied. However, conventional NDT method cannot be applied to the real-size PSC girder because the PS tendons could not be approached. To measure the tensile force of real-size PSC girder, this study proposed embedded EM sensor based tensile force estimation method. The embedded EM sensor could be installed inside of PSC girder as a sheath joint before the concrete casting. After curing process, the PS tendons were installed, and the tensile force was induced step by step using hydraulic jacking machine. The B-H loop was measured using embedded EM sensor at each tensile force steps and to compare with actual tensile force, the load cell was installed at each end of girder. The magnetization energy loss, that is the closed area of B-H loop, was decreased according to the increase of tensile force with regular pattern. Thus, the tensile force could be estimated by the tracking the change of magnetization energy loss of PS tendons. Through the experimental result, the proposed method can be used to estimate the tensile force of the in-situ real-size PSC girder bridge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tensile%20force%20estimation" title="tensile force estimation">tensile force estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20EM%20sensor" title=" embedded EM sensor"> embedded EM sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetization%20energy%20loss" title=" magnetization energy loss"> magnetization energy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=PSC%20girder" title=" PSC girder"> PSC girder</a> </p> <a href="https://publications.waset.org/abstracts/57237/tensile-force-estimation-for-real-size-pre-stressed-concrete-girder-using-embedded-elasto-magnetic-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57237.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">20696</span> Pressure-Detecting Method for Estimating Levitation Gap Height of Swirl Gripper</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaige%20Shi">Kaige Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20Jiang"> Chao Jiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Li"> Xin Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The swirl gripper is an electrically activated noncontact handling device that uses swirling airflow to generate a lifting force. This force can be used to pick up a workpiece placed underneath the swirl gripper without any contact. It is applicable, for example, in the semiconductor wafer production line, where contact must be avoided during the handling and moving of a workpiece to minimize damage. When a workpiece levitates underneath a swirl gripper, the gap height between them is crucial for safe handling. Therefore, in this paper, we propose a method to estimate the levitation gap height by detecting pressure at two points. The method is based on theoretical model of the swirl gripper, and has been experimentally verified. Furthermore, the force between the gripper and the workpiece can also be estimated using the detected pressure. As a result, the nonlinear relationship between the force and gap height can be linearized by adjusting the rotating speed of the fan in the swirl gripper according to the estimated force and gap height. The linearized relationship is expected to enhance handling stability of the workpiece. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swirl%20gripper" title="swirl gripper">swirl gripper</a>, <a href="https://publications.waset.org/abstracts/search?q=noncontact%20handling" title=" noncontact handling"> noncontact handling</a>, <a href="https://publications.waset.org/abstracts/search?q=levitation" title=" levitation"> levitation</a>, <a href="https://publications.waset.org/abstracts/search?q=gap%20height%20estimation" title=" gap height estimation"> gap height estimation</a> </p> <a href="https://publications.waset.org/abstracts/109800/pressure-detecting-method-for-estimating-levitation-gap-height-of-swirl-gripper" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109800.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">133</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">20695</span> Research on Axial End Flux Leakage and Detent Force of Transverse Flux PM Linear Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20R.%20Li">W.

The present research work aims to develop a mechanistic cutting force model and to study the mechanistic constants used in the force model in case of turning operation. The proposed model can be used for the reliable and accurate estimation of the cutting forces establishing relationship of various force components (cutting force and feed force) with uncut chip thickness. The accurate estimation of cutting force is required to improve thin-walled part accuracy by controlling the tool-work piece deflection induced surface errors and tool-work piece vibration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=turning" title="turning">turning</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20forces" title=" cutting forces"> cutting forces</a>, <a href="https://publications.waset.org/abstracts/search?q=cutting%20constants" title=" cutting constants"> cutting constants</a>, <a href="https://publications.waset.org/abstracts/search?q=uncut%20chip%20thickness" title=" uncut chip thickness"> uncut chip thickness</a> </p> <a href="https://publications.waset.org/abstracts/30832/a-method-to-determine-cutting-force-coefficients-in-turning-using-mechanistic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30832.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">522</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">20693</span> An Optimal Control Model to Determine Body Forces of Stokes Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuanhao%20Gao">Yuanhao Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Pin%20Lin"> Pin Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Kees%20Weijer"> Kees Weijer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we will determine the external body force distribution with analysis of stokes fluid motion using mathematical modelling and numerical approaching. The body force distribution is regarded as the unknown variable and could be determined by the idea of optimal control theory. The Stokes flow motion and its velocity are generated by given forces in a unit square domain. A regularized objective functional is built to match the numerical result of flow velocity with the generated velocity data. So that the force distribution could be determined by minimizing the value of objective functional, which is also the difference between the numerical and experimental velocity. Then after utilizing the Lagrange multiplier method, some partial differential equations are formulated consisting the optimal control system to solve.

Using the constant down force by AFM and SDFE theory and following the experimental cutting path planning, the cutting depth and width of each pass of Y shape nanochannel can be predicted by simulation. The paper plans the path for cutting the burr at the edge of Y shape nanochannel. Then, it carries out cutting the burr along the Y nanochannel edge by using a smaller down force.

The gripper is constructed based on the concept of compliant mechanism with flexure hinge. A passive force regulation mechanism is presented to control the grasping force a micro-sized object instead of using a sensor force. The force regulation mechanism is designed using the planar springs. The gripper is expected to obtain a large range of displacement to handle various sized objects. First of all, the statics and dynamics of the gripper are investigated by using the finite element analysis in ANSYS software. And then, the design parameters of the gripper are optimized via Taguchi method. An orthogonal array <em>L<sub>9</sub></em> is used to establish an experimental matrix. Subsequently, the signal to noise ratio is analyzed to find the optimal solution. Finally, the response surface methodology is employed to model the relationship between the design parameters and the output displacement of the gripper. The design of experiment method is then used to analyze the sensitivity so as to determine the effect of each parameter on the displacement. The results showed that the compliant gripper can move with a large displacement of 213.51 mm and the force regulation mechanism is expected to be used for high precision positioning systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexure%20hinge" title="flexure hinge">flexure hinge</a>, <a href="https://publications.waset.org/abstracts/search?q=compliant%20mechanism" title=" compliant mechanism"> compliant mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=compliant%20gripper" title=" compliant gripper"> compliant gripper</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20regulation%20mechanism" title=" force regulation mechanism"> force regulation mechanism</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a> </p> <a href="https://publications.waset.org/abstracts/61596/design-and-optimization-for-a-compliant-gripper-with-force-regulation-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61596.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">331</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20689</span> Effect of Coriolis Force on Magnetoconvection in an Anisotropic Porous Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20F.%20M.%20Mokhtar">N.

Although this phenomenon may have positive implications for individual careers and destination organizations, the consequences for the source organizations losing workers are less clear. The aim of this paper is thus to develop a comprehensive typology of possible inter-organizational employee mobility determinants. Since the most common classification differentiates between mobility determinants at different levels (i.e., economic, organizational, and individual), this paper focuses on building a comprehensive multi-level typology of inter-organizational mobility determinants across diverse sectors and industries. By using a structured literature review approach and bibliometric analysis, the paper reveals both intricate relationships between different mobility determinants and the complexity of inter-organizational networks and social ties. The latter appears as both a mobility determinant (at the organizational and individual level) and a mobility effect. Indeed, inter-organizational employee mobility leads to the formation of networks between source and destination organizations. These networks are practically based on the social ties between mobile employees and their colleagues and, in this way, they close the "inter-organizational employee mobility - inter-organizational network/ties" circle. The paper contributes to the career development literature by uncovering hitherto underexplored diverse determinants of intra- and inter-sectoral mobility as well as the conflicting results of the existing studies on some factors (e.g., inter-organizational networks and/or social ties) that appear both as a mobility determinant and a mobility effect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter-organizational%20mobility" title="inter-organizational mobility">inter-organizational mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20ties" title=" social ties"> social ties</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-organizational%20network" title=" inter-organizational network"> inter-organizational network</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20transfer" title=" knowledge transfer"> knowledge transfer</a> </p> <a href="https://publications.waset.org/abstracts/150860/systematic-literature-review-and-bibliometric-analysis-of-interorganizational-employee-mobility-determinants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150860.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">115</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">20687</span> Non-Linear Control in Positioning of PMLSM by Estimates of the Load Force by MRAS Method </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maamar%20Yahiaoui">Maamar Yahiaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrrahmene%20Kechich"> Abdelrrahmene Kechich</a>, <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Elkhallile%20Bousserhene"> Ismail Elkhallile Bousserhene</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article presents a study in simulation by means of MATLAB/Simulink software of the nonlinear control in positioning of a linear synchronous machine with the esteemed force of load, to have effective control in the estimator in all tests the wished trajectory follows and the disturbance of load start.

Unfortunately, user comfort was not always a priority design criterion throughout their development. To further improve this technology, exoskeletons should operate and deliver assistance without causing discomfort to the user. For this, improvements are necessary from an ergonomic point of view. The device’s control method is important when endeavoring to enhance user comfort. Exoskeleton or rehabilitation device controllers use methods of control called interaction controls (admittance and impedance controls). This paper proposes an extended version of an admittance controller to enhance user comfort. The control method used consists of adding an inner loop that is controlled by a proportional-integral-derivative (PID) controller. This allows the interaction force to be kept as close as possible to the desired force trajectory. The force-tracking admittance controller modifies the actuation force of the system in order to follow both the desired motion trajectory and the desired relative force between the user and the exoskeleton. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mobility%20assistive%20device" title="mobility assistive device">mobility assistive device</a>, <a href="https://publications.waset.org/abstracts/search?q=exoskeleton" title=" exoskeleton"> exoskeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=force-tracking%20admittance%20controller" title=" force-tracking admittance controller"> force-tracking admittance controller</a>, <a href="https://publications.waset.org/abstracts/search?q=user%20comfort" title=" user comfort"> user comfort</a> </p> <a href="https://publications.waset.org/abstracts/133918/enhancing-human-mobility-exoskeleton-comfort-using-admittance-controller" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133918.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20685</span> Key Technologies and Evolution Strategies for Computing Force Bearer Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhaojunfeng">Zhaojunfeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Driven by the national policy of "East Data and Western Calculation", the computing first network will attract a new wave of development.

The effect of turbulence on the slope stability of an earthen levee strengthened by high performance turf reinforcement mat (HPTRM) is investigated in this study for combined storm surge and wave overtopping conditions. The results show that turbulence has strong influence on the slope stability during the combined storm surge and wave overtopping conditions. Among the surge height, peak wave force and turbulent force. The turbulent force has the ability to stabilize the earthen levee at the large wave force the turbulent force has strongest effect on the FS. The surge storm acts as an independent force on the slope stability of the earthen levee. It just adds to the effects of the turbulent force and wave force on the slope stability of HPTRM strengthened levee. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=slope%20stability" title="slope stability">slope stability</a>, <a href="https://publications.waset.org/abstracts/search?q=strength%20reduction%20method" title=" strength reduction method"> strength reduction method</a>, <a href="https://publications.waset.org/abstracts/search?q=HPTRM" title=" HPTRM"> HPTRM</a>, <a href="https://publications.waset.org/abstracts/search?q=levee" title=" levee"> levee</a>, <a href="https://publications.waset.org/abstracts/search?q=overtopping" title=" overtopping "> overtopping </a> </p> <a href="https://publications.waset.org/abstracts/17649/slope-stability-of-an-earthen-levee-strengthened-by-hptrm-under-turbulent-overtopping-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17649.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">364</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">20683</span> A Machining Method of Cross-Shape Nano Channel and Experiments for Silicon Substrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zone-Ching%20Lin">Zone-Ching Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao-Yuan%20Jheng"> Hao-Yuan Jheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zih-Wun%20Jhang"> Zih-Wun Jhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper innovatively proposes using the concept of specific down force energy (SDFE) and AFM machine to establish a machining method of cross-shape nanochannel on single-crystal silicon substrate. As for machining a cross-shape nanochannel by AFM machine, the paper develop a method of machining cross-shape nanochannel groove at a fixed down force by using SDFE theory and combining the planned cutting path of cross-shape nanochannel up to 5th machining layer it finally achieves a cross-shape nanochannel at a cutting depth of around 20nm. Since there may be standing burr at the machined cross-shape nanochannel edge, the paper uses a smaller down force to cut the edge of the cross-shape nanochannel in order to lower the height of standing burr and converge the height of standing burr at the edge to below 0.54nm as set by the paper. Finally, the paper conducts experiments of machining cross-shape nanochannel groove on single-crystal silicon by AFM probe, and compares the simulation and experimental results.

The displacement information of degrees of freedom with Brownian motions at a given temperature in space emerges as an entropic force between species. Here, we use this concept of entropy to understand the underlying physics behind the formation of attractive and repulsive forces by imagining that space is filled with free Brownian degrees of freedom. We incorporate the radius of bodies and the distance between them into entropic force relation systematically. Using this modified gravitational entropic force, we derive the attractive entropic force between bodies without considering their spin. We further hypothesize a possible mechanism for the formation of the repulsive force between two bodies. We visually elaborate that the repulsive entropic force will be manifested through the rotation of degrees of freedom around the spinning particles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entropy" title="entropy">entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=information" title=" information"> information</a>, <a href="https://publications.waset.org/abstracts/search?q=force" title=" force"> force</a>, <a href="https://publications.waset.org/abstracts/search?q=Brownian%20Motions" title=" Brownian Motions"> Brownian Motions</a> </p> <a href="https://publications.waset.org/abstracts/150175/a-deep-explanation-for-the-formation-of-force-as-a-foundational-law-of-physics-by-incorporating-unknown-degrees-of-freedom-into-space" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150175.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">76</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20681</span> Soret-Driven Convection in a Binary Fluid with Coriolis Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20H.%20Z.%20Abidin">N.

It is implicitly indicative of the mental image of a physical environment in which the residents enjoy strong social ties. Sense of community, a crucial factor in improving quality of life and social welfare, leads to life satisfaction in a residential community. Despite the important functions of such a notion, few empirical studies, to the best of the authors' knowledge, have been so far carried out in Iran to investigate the effective factors in sharpening the sense of community in residential communities. This survey research examined sense of community in 360 above 20-year old residents of three residential communities in Tehran, Iran using cluster sampling and questionnaire. The study yielded the result that variables of local social ties, social control and trust, sense of security, length of residence, use of public spaces, and mixed land use have a significant relationship with sense of community. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20community" title="sense of community">sense of community</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20social%20ties" title=" local social ties"> local social ties</a>, <a href="https://publications.waset.org/abstracts/search?q=sense%20of%20security" title=" sense of security"> sense of security</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20space" title=" public space"> public space</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20community" title=" residential community"> residential community</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran" title=" Tehran"> Tehran</a> </p> <a href="https://publications.waset.org/abstracts/128887/factors-affecting-sense-of-community-in-residential-communities-case-study-residential-communities-in-tehran-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128887.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">188</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">20679</span> Evaluation of Joint Contact Forces and Muscle Forces in the Subjects with Non-Specific Low Back Pain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Taghi%20Karimi">Mohammad Taghi Karimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Hasan%20Zahraee"> Maryam Hasan Zahraee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Low back pain (LBP) is a common health and socioeconomic problem, especially the chronic one. The joint contact force is an important parameter during walking which increases the incidence of injury and degenerative joint disease. To our best knowledge, there are not enough evidences in literature on the muscular forces and joint contact forces in subjects with low back pain. Purpose: The main hypothesis associated with this research was that joint contact force of L4/L5 of non-specific chronic low back pain subjects was the same as that of normal. Therefore, the aim of this study was to determine the joint contact force difference between non-specific chronic low back pain and normal subjects. Method: This was an experimental-comparative study. 20 normal subjects and 20 non-specific chronic low back pain patients were recruited in this study. Qualysis motion analysis system and a Kistler force plate were used to collect the motions and the force applied on the leg, respectively. OpenSimm software used to determine joint contact force and muscle forces in this study. Some parameters such as force applied on the legs (pelvis), kinematic of hip and pelvic, peaks of muscles, force of trunk musculature and joint contact force of L5/S1 were used for further analysis. Differences between mean values of all data were measured using two-sample t-test among the subjects. Results: The force produced by Semitendinosus, Biceps Femoris, and Adductor muscles were significantly different between low back pain and normal subjects. Moreover, the mean value of breaking component of the force of the knee joint increased significantly in low back pain subjects, besides a significant decrease in mean value of the vertical component of joint reaction force compared to the normal ones. Conclusions: The forces produced by the trunk and pelvic muscles, and joint contact forces differ significantly between low back pain and normal subjects. It seems that those with non-specific chronic low back pain use trunk muscles more than normal subjects to stabilize the pelvic during walking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20contact%20force" title=" joint contact force"> joint contact force</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic" title=" kinetic"> kinetic</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20force" title=" muscle force"> muscle force</a> </p> <a href="https://publications.waset.org/abstracts/88748/evaluation-of-joint-contact-forces-and-muscle-forces-in-the-subjects-with-non-specific-low-back-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88748.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">238</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">20678</span> Numerical Modeling to Validate Theoretical Models of Toppling Failure in Rock Slopes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hooman%20Dabirmanesh">Hooman Dabirmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Attila%20M.%20Zsaki"> Attila M.

In these equilibrium methods, internal forces exerted between columns are not clearly defined, and to the authors’ best knowledge, there is no consensus in literature with respect to the results of analysis. A discrete element method-based numerical model was developed and applied to simulate the behavior of rock layers subjected to toppling failure. Based on this calibrated numerical model, a study of the location and distribution of internal forces that result in equilibrium was carried out. The sum of side forces was applied at a point on a block which properly represents the force to determine the inter-column force distribution. In terms of the side force distribution coefficient, the result was compared to those obtained from laboratory centrifuge tests. The results of the simulation show the suitable criteria to select the correct position for the internal exerted force between rock layers. In addition, the numerical method demonstrates how a theoretical method could be reliable by considering the interaction between the rock layers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20bond" title="contact bond">contact bond</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20element" title=" discrete element"> discrete element</a>, <a href="https://publications.waset.org/abstracts/search?q=force%20distribution" title=" force distribution"> force distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=limit%20equilibrium" title=" limit equilibrium"> limit equilibrium</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20stress" title=" tensile stress"> tensile stress</a> </p> <a href="https://publications.waset.org/abstracts/92611/numerical-modeling-to-validate-theoretical-models-of-toppling-failure-in-rock-slopes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92611.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20677</span> Bending Tests for the Axial Load Identifications in Space Structures with Unknown Boundary Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Bonopera">M.

The non-destructive method requires the knowledge of the beam-column flexural rigidity only. Flexural displacements are measured at five cross sections along the beam-column subjected to an additional vertical load at the mid-span. Unlike analogous dynamic methods, any set of experimental data may be used in the identification procedure. The method is verified by means of many numerical and experimental tests on beam-columns having unknown boundary conditions and different slenderness belonging to three different space prototypes in small-scale. Excellent estimates of the tensile and compressive forces are obtained for the elements with higher slenderness and when the greatest possible distance between sensors is adopted. Moreover, the application of larger values of the vertical load and very accurate displacement measurements are required. The method could be an efficacious technique in-situ, considering that safety inspections will become increasingly important in the near future, especially because of the improvement of the material properties that allowed designing space structures composed of beam-columns with higher slenderness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=force%20identification" title="force identification">force identification</a>, <a href="https://publications.waset.org/abstracts/search?q=in-situ%20test" title=" in-situ test"> in-situ test</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20structure" title=" space structure"> space structure</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20test" title=" static test"> static test</a> </p> <a href="https://publications.waset.org/abstracts/50354/bending-tests-for-the-axial-load-identifications-in-space-structures-with-unknown-boundary-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50354.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">20676</span> Direct Displacement-Based Design Procedure for Performance-Based Seismic Design of Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haleh%20Hamidpour">Haleh Hamidpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since the seismic damageability of structures is controlled by the inelastic deformation capacities of structural elements, seismic design of structure based on force analogy methods is not appropriate. In recent year, the basic approach of design codes have been changed from force-based approach to displacement-based. In this regard, a Direct Displacement-Based Design (DDBD) and a Performance-Based Plastic Design (PBPD) method are proposed. In this study, the efficiency of these two methods on seismic performance of structures is evaluated through a sample 12-story reinforced concrete moment frame. The building is designed separately based on the DDBD and the PBPD methods. Once again the structure is designed by the traditional force analogy method according to the FEMA P695 regulation. Different design method results in different structural elements. Seismic performance of these three structures is evaluated through nonlinear static and nonlinear dynamic analysis. The results show that the displacement-based design methods accommodate the intended performance objectives better than the traditional force analogy method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20performance-based%20design" title="direct performance-based design">direct performance-based design</a>, <a href="https://publications.waset.org/abstracts/search?q=ductility%20demands" title=" ductility demands"> ductility demands</a>, <a href="https://publications.waset.org/abstracts/search?q=inelastic%20seismic%20performance" title=" inelastic seismic performance"> inelastic seismic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20mechanism" title=" yield mechanism"> yield mechanism</a> </p> <a href="https://publications.waset.org/abstracts/51079/direct-displacement-based-design-procedure-for-performance-based-seismic-design-of-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51079.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">333</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">20675</span> Estimating the Technological Deviation Impact on the Value of the Output Parameter of the Induction Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marinka%20K.%20Baghdasaryan">Marinka K.

By the method of experiment planning, the expression of a polynomial for the electromotive force which can be used to estimate the adequacy of mathematical models to be used at the investigation and design of induction converters is obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20converter" title="induction converter">induction converter</a>, <a href="https://publications.waset.org/abstracts/search?q=electromotive%20force" title=" electromotive force"> electromotive force</a>, <a href="https://publications.waset.org/abstracts/search?q=expectation" title=" expectation"> expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=technological%20spread" title=" technological spread"> technological spread</a>, <a href="https://publications.waset.org/abstracts/search?q=deviation" title=" deviation"> deviation</a>, <a href="https://publications.waset.org/abstracts/search?q=planning%20an%20experiment" title=" planning an experiment"> planning an experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=polynomial" title=" polynomial"> polynomial</a>, <a href="https://publications.waset.org/abstracts/search?q=confidence%20level" title=" confidence level"> confidence level</a> </p> <a href="https://publications.waset.org/abstracts/18946/estimating-the-technological-deviation-impact-on-the-value-of-the-output-parameter-of-the-induction-converter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20674</span> Trajectory Tracking of a Redundant Hybrid Manipulator Using a Switching Control Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atilla%20Bayram">Atilla Bayram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the trajectory tracking control of a spatial redundant hybrid manipulator. This manipulator consists of two parallel manipulators which are a variable geometry truss (VGT) module. In fact, each VGT module with 3-degress of freedom (DOF) is a planar parallel manipulator and their operational planes of these VGT modules are arranged to be orthogonal to each other. Also, the manipulator contains a twist motion part attached to the top of the second VGT module to supply the missing orientation of the endeffector. These three modules constitute totally 7-DOF hybrid (parallel-parallel) redundant spatial manipulator. The forward kinematics equations of this manipulator are obtained, then, according to these equations, the inverse kinematics is solved based on an optimization with the joint limit avoidance. The dynamic equations are formed by using virtual work method. In order to test the performance of the redundant manipulator and the controllers presented, two different desired trajectories are followed by using the computed force control method and a switching control method. The switching control method is combined with the computed force control method and genetic algorithm. In the switching control method, the genetic algorithm is only used for fine tuning in the compensation of the trajectory tracking errors. <p class="card-text"><strong>Keywords:</strong> <a
