The proposed machine is capable of operating as a direct drive double fed wind generator (DDDF, D3F) because it requires no gearbox and only a reduced-size converter. A wind turbine drive built around a D3F generator is cheaper to manufacture, requires less maintenance, and has a higher energy yield than its conventional counterparts. The single tooth wound generator of a D3F turbine has superb volume utilization and lower stator I2R losses due to its extremely short-end windings. Both stator and rotor of a D3F generator can be manufactured in segments, which simplifies its assembly and transportation to the site, and makes production cheaper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20drive" title="direct drive">direct drive</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20fed%20generator" title=" double fed generator"> double fed generator</a>, <a href="https://publications.waset.org/abstracts/search?q=gearbox" title=" gearbox"> gearbox</a>, <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20generators" title=" permanent magnet generators"> permanent magnet generators</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20tooth%20winding" title=" single tooth winding"> single tooth winding</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20power" title=" wind power"> wind power</a> </p> <a href="https://publications.waset.org/abstracts/152197/direct-drive-double-fed-wind-generator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152197.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">190</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">4043</span> Thermal Assessment of Outer Rotor Direct Drive Gearless Small-Scale Wind Turbines </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Yasa">Yusuf Yasa</a>, <a href="https://publications.waset.org/abstracts/search?q=Erkan%20Mese"> Erkan Mese</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the thermal issue of permanent magnet synchronous generator which is frequently used in direct drive gearless small-scale wind turbine applications.

Each type of the machines provides distinguishable geometrical features such as narrow width with a large diameter for the AFPM-type machine and wide width with a certain diameter for the RFPM-type machine. When the AFPM-type machine is applied, an increase of electric power production through a multi-stage arrangement in axial direction is easily achieved. On the other hand, the RFPM-type machine can be applied by using its geometric feature of wide width. In this study, a hybrid two-stage direct-drive generator for 6.2MW class wind turbine was proposed, in which the two-stage AFPM-type machine for 5 MW was composed of two models arranged in axial direction with a hollow shape topology of the rotor with annular disc, the stator and the main shaft mounted on coupled slew bearings. In addition, the RFPM-type machine for 1.2MW was installed at the empty space of the rotor. Analytic results obtained from an electro-magnetic and structural interaction analysis showed that the structural weight of the proposed hybrid two-stage direct-drive generator can be achieved as 155tonf in a condition satisfying the requirements of structural behaviors such as allowable air-gap clearance and strength. Therefore, it was sure that the 6.2MW hybrid two-stage direct-drive generator is competitive than conventional generators.

Kouzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to have stable and high performance of direct torque and flux control (DTFC) of double star induction motor drive (DSIM), proper on-line adaptation of the stator resistance is very important. This is inevitably due to the variation of the stator resistance during operating conditions, which introduces error in estimated flux position and the magnitude of the stator flux. Error in the estimated stator flux deteriorates the performance of the DTFC drive. Also, the effect of error in estimation is very important especially at low speed. Due to this, our aim is to overcome the sensitivity of the DTFC to the stator resistance variation by proposing on-line fuzzy estimation stator resistance. The fuzzy estimation method is based on an on-line stator resistance correction through the variations of the stator current estimation error and its variations. The fuzzy logic controller gives the future stator resistance increment at the output. The main advantage of the suggested algorithm control is to avoid the drive instability that may occur in certain situations and ensure the tracking of the actual stator resistance. The validity of the technique and the improvement of the whole system performance are proved by the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=direct%20torque%20control" title="direct torque control">direct torque control</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20stator%20induction%20motor" title=" dual stator induction motor"> dual stator induction motor</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuzzy%20Logic%20estimation" title=" Fuzzy Logic estimation"> Fuzzy Logic estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=stator%20resistance%20adaptation" title=" stator resistance adaptation"> stator resistance adaptation</a> </p> <a href="https://publications.waset.org/abstracts/48798/high-performance-of-direct-torque-and-flux-control-of-a-double-stator-induction-motor-drive-with-a-fuzzy-stator-resistance-estimator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48798.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4039</span> Improvement of Direct Torque and Flux Control of Dual Stator Induction Motor Drive Using Intelligent Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kouzi%20Katia">Kouzi Katia</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a Direct Torque Control (DTC) algorithm of dual Stator Induction Motor (DSIM) drive using two approach intelligent techniques: Artificial Neural Network (ANN) approach replaces the switching table selector block of conventional DTC and Mamdani Fuzzy Logic controller (FLC) is used for stator resistance estimation.

The result indicated: the differential drive assisted steering algorithm could provide enough steering drive-assisted under low speed and improve the steering portability. Along with the increase of the speed, the provided steering drive-assisted decreased. With the control algorithm, the steering stiffness of the steering system increased along with the increase of the speed, which ensures the driver’s road feeling. The control algorithm of differential drive assisted steering could avoid the understeer under low speed effectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=differential%20assisted%20steering" title="differential assisted steering">differential assisted steering</a>, <a href="https://publications.waset.org/abstracts/search?q=control%20strategy" title=" control strategy"> control strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20drive%20electric%20vehicle" title=" distributed drive electric vehicle"> distributed drive electric vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=driving%2Fbraking%20torque" title=" driving/braking torque"> driving/braking torque</a> </p> <a href="https://publications.waset.org/abstracts/11277/research-on-control-strategy-of-differential-drive-assisted-steering-of-distributed-drive-electric-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11277.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">478</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">4035</span> Direct Torque Control of Induction Motor Employing Differential Evolution Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Vamsee%20Kiran">T.

According to LLMDE theory, language learning can be understood as a means of engaging one or more of four self-fulfillment drives: the drive to expand one’s horizons (perspective drive); the drive to make a success of oneself (status drive); the drive to engage in interaction with others (communication drive); and the drive to obtain intellectual and affective stimulation (entertainment drive). While many theories of learner psychology focus on conscious agency, LLMDE theory addresses the role of the unconscious. In addition, supplementary thematic analysis of the data revealed the role of context in mediating drive engagement. Unexpected memorable events, for example, play a key role in instigating and, indirectly, in regulating learning, as do institutional and cultural contexts. Given the apparent importance of such factors beyond the immediate control of the learner, and given the pervasive role of habit and drives, it is argued that the concept of motivation merits theoretical reappraisal. Rather than an underlying force determining language learning success or failure, it can be understood to emerge sporadically in consciousness to promote behavioral change, or to protect habitual behavior from disruption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drives" title="drives">drives</a>, <a href="https://publications.waset.org/abstracts/search?q=grounded%20theory" title=" grounded theory"> grounded theory</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=significant%20events" title=" significant events"> significant events</a> </p> <a href="https://publications.waset.org/abstracts/138583/language-learning-drives-and-context-a-grounded-theory-of-learning-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138583.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4033</span> Modeling and System Identification of a Variable Excited Linear Direct Drive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heiko%20Wei%C3%9F">Heiko Weiß</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20Meister"> Andreas Meister</a>, <a href="https://publications.waset.org/abstracts/search?q=Christoph%20Ament"> Christoph Ament</a>, <a href="https://publications.waset.org/abstracts/search?q=Nils%20Dreifke"> Nils Dreifke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Linear actuators are deployed in a wide range of applications. This paper presents the modeling and system identification of a variable excited linear direct drive (LDD). The LDD is designed based on linear hybrid stepper technology exhibiting the characteristic tooth structure of mover and stator. A three-phase topology provides the thrust force caused by alternating strengthening and weakening of the flux of the legs. To achieve best possible synchronous operation, the phases are commutated sinusoidal. Despite the fact that these LDDs provide high dynamics and drive forces, noise emission limits their operation in calm workspaces. To overcome this drawback an additional excitation of the magnetic circuit is introduced to LDD using additional enabling coils instead of permanent magnets. The new degree of freedom can be used to reduce force variations and related noise by varying the excitation flux that is usually generated by permanent magnets. Hence, an identified simulation model is necessary to analyze the effects of this modification. Especially the force variations must be modeled well in order to reduce them sufficiently. The model can be divided into three parts: the current dynamics, the mechanics and the force functions. These subsystems are described with differential equations or nonlinear analytic functions, respectively. Ordinary nonlinear differential equations are derived and transformed into state space representation. Experiments have been carried out on a test rig to identify the system parameters of the complete model. Static and dynamic simulation based optimizations are utilized for identification. The results are verified in time and frequency domain. Finally, the identified model provides a basis for later design of control strategies to reduce existing force variations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=force%20variations" title="force variations">force variations</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20direct%20drive" title=" linear direct drive"> linear direct drive</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling%20and%20system%20identification" title=" modeling and system identification"> modeling and system identification</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20excitation%20flux" title=" variable excitation flux"> variable excitation flux</a> </p> <a href="https://publications.waset.org/abstracts/58717/modeling-and-system-identification-of-a-variable-excited-linear-direct-drive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58717.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">370</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">4032</span> Developing a Regulator for Improving the Operation Modes of the Electrical Drive Motor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baghdasaryan%20Marinka">Baghdasaryan Marinka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The operation modes of the synchronous motors used in the production processes are greatly conditioned by the accidentally changing technological and power indices.  As a result, the electrical drive synchronous motor may appear in irregular operation regimes. Although there are numerous works devoted to the development of the regulator for the synchronous motor operation modes, their application for the motors working in the irregular modes is not expedient. In this work, to estimate the issues concerning the stability of the synchronous electrical drive system, the transfer functions of the electrical drive synchronous motors operating in the synchronous and induction modes have been obtained.  For that purpose, a model for investigating the frequency characteristics has been developed in the LabView environment. Frequency characteristics for assessing the transient process of the electrical drive system, operating in the synchronous and induction modes have been obtained, and based on their assessment, a regulator for improving the operation modes of the motor has been proposed. The proposed regulator can be successfully used to prevent the irregular modes of the electrical drive synchronous motor, as well as to estimate the operation state of the drive motor of the mechanism with a changing load. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrical%20drive%20system" title="electrical drive system">electrical drive system</a>, <a href="https://publications.waset.org/abstracts/search?q=synchronous%20motor" title=" synchronous motor"> synchronous motor</a>, <a href="https://publications.waset.org/abstracts/search?q=regulator" title=" regulator"> regulator</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=transition%20process" title=" transition process"> transition process</a> </p> <a href="https://publications.waset.org/abstracts/105307/developing-a-regulator-for-improving-the-operation-modes-of-the-electrical-drive-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105307.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">4031</span> Direct Torque Control of Induction Motor Employing Teaching Learning Based Optimization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anam%20Gopi">Anam Gopi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The undesired torque and flux ripple may occur in conventional direct torque control (DTC) induction motor drive.

The results of this study indicate that if the weight is the main concern, a shaft made of Carbon/Epoxy can be a good option, and if the cost is a more important parameter, a hybrid shaft made of aluminum and Carbon/Epoxy can be considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bending%20natural%20frequency" title="Bending natural frequency">Bending natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=Composite%20drive%20shaft" title=" Composite drive shaft"> Composite drive shaft</a>, <a href="https://publications.waset.org/abstracts/search?q=Peak%20torque" title=" Peak torque"> Peak torque</a>, <a href="https://publications.waset.org/abstracts/search?q=Torsional%20buckling" title=" Torsional buckling"> Torsional buckling</a> </p> <a href="https://publications.waset.org/abstracts/96457/design-and-analysis-of-a-laminated-composite-automotive-drive-shaft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96457.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">232</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4024</span> Computational Fluid Dynamics Simulations of Thermal and Flow Fields inside a Desktop Personal Computer Cabin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Salehi">Mohammad Salehi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Erfan%20Doraki"> Mohammad Erfan Doraki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, airflow analysis inside a desktop computer case is performed by simulating computational fluid dynamics. The purpose is to investigate the cooling process of the central processing unit (CPU) with thermal capacities of 80 and 130 watts. The airflow inside the computer enclosure, selected from the microATX model, consists of the main components of heat production such as CPU, hard disk drive, CD drive, floppy drive, memory card and power supply unit; According to the amount of thermal power produced by the CPU with 80 and 130 watts of power, two different geometries have been used for a direct and radial heat sink. First, the independence of the computational mesh and the validation of the solution were performed, and after ensuring the correctness of the numerical solution, the results of the solution were analyzed. The simulation results showed that changes in CPU temperature and other components linearly increased with increasing CPU heat output. Also, the ambient air temperature has a significant effect on the maximum processor temperature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=CPU%20cooling" title=" CPU cooling"> CPU cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20case%20simulation" title=" computer case simulation"> computer case simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20sink" title=" heat sink"> heat sink</a> </p> <a href="https://publications.waset.org/abstracts/134116/computational-fluid-dynamics-simulations-of-thermal-and-flow-fields-inside-a-desktop-personal-computer-cabin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134116.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">122</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">4023</span> Fatigue Life Estimation Using N-Code for Drive Shaft of Passenger Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae%20An%20Kim">Tae An Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyo%20Lim%20Kang"> Hyo Lim Kang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Won%20Han"> Hye Won Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Ho%20Han"> Seung Ho Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The drive shaft of passenger vehicle has its own function such as transmitting the engine torque from the gearbox and differential gears to the wheels. It must also compensate for all variations in angle or length resulting from manoeuvring and deflection for perfect synchronization between joints. Torsional fatigue failures occur frequently at the connection parts of the spline joints in the end of the drive shaft. In this study, the fatigue life of a drive shaft of passenger vehicle was estimated by using the finite element analysis. A commercial software of n-Code was applied under twisting load conditions, i.e. 0~134kgf•m and 0~188kgf•m, in which the shear strain range-fatigue life relationship considering Signed Shear method, Smith-Watson-Topper equation, Neuber-Hoffman Seeger method, size sensitivity factor and surface roughness effect was taken into account. The estimated fatigue life was verified by a twisting load test of the real drive shaft in a test rig.

An increase in the number of idle pulleys results in the increase of frictional power. Further, components like idler and belt tensioner are also needed to run the belt drive which adds to the frictional power. The aspiration of this paper is to minimize the friction power by introducing a new system that could combine all the accessories in one shaft within a single casing. This is conceptualized to minimize the friction power, service and maintenance cost, space and also time. The validation of this work can be executed through a simpler drive transmitting power from the crank shaft. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20drive" title="single drive">single drive</a>, <a href="https://publications.waset.org/abstracts/search?q=idler%20pulley" title=" idler pulley"> idler pulley</a>, <a href="https://publications.waset.org/abstracts/search?q=belt%20tensioner" title=" belt tensioner"> belt tensioner</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20power" title=" friction power"> friction power</a>, <a href="https://publications.waset.org/abstracts/search?q=casing" title=" casing"> casing</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20and%20cost" title=" space and cost"> space and cost</a> </p> <a href="https://publications.waset.org/abstracts/9477/development-of-a-single-drive-for-the-accessories-components-in-ic-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9477.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">4020</span> Soft Exoskeleton Elastomer Pre-Tension Drive Control System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Andrey%20Yatsun">Andrey Yatsun</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrei%20Malchikov"> Andrei Malchikov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exoskeletons are used to support and compensate for the load on the human musculoskeletal system. Elastomers are an important component of exoskeletons, providing additional support and compensating for the load. The algorithm of the active elastomer tension system provides the required auxiliary force depending on the angle of rotation and the tilt speed of the operator's torso. Feedback for the drive is provided by a force sensor integrated into the attachment of the exoskeleton vest. The use of direct force measurement ensures the required accuracy in all settings of the man-machine system. Non-adjustable elastic elements make it difficult to move without load, tilt forward and walk. A strategy for the organization of the auxiliary forces management system is proposed based on the allocation of 4 operating modes of the human-machine system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20exoskeleton" title="soft exoskeleton">soft exoskeleton</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-tension%20elastomer" title=" pre-tension elastomer"> pre-tension elastomer</a>, <a href="https://publications.waset.org/abstracts/search?q=human-machine%20interaction" title=" human-machine interaction"> human-machine interaction</a> </p> <a href="https://publications.waset.org/abstracts/183948/soft-exoskeleton-elastomer-pre-tension-drive-control-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183948.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">66</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">4019</span> Backstepping Sliding Mode Control </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Othmane%20Boughazi">Othmane Boughazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelmadjid%20Boumedienne"> Abdelmadjid Boumedienne</a>, <a href="https://publications.waset.org/abstracts/search?q=Hachemi%20Glaoui"> Hachemi Glaoui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work treats the modeling and simulation of non-linear system behavior of an induction motor using backstepping sliding mode control.

Moreover, if we look at the road structure, it is almost impossible to stop at a point and text. With the introduction of TEXT STOPs, drivers will be able to stop different stops for a maximum of 1 and a half-minute in order to reply or write a message. They can be introduced at a distance of 10 minutes of driving on the average speed of the road, so the drivers can look forward to a stop and can reply to a text when needed.

Various gene drive mechanisms, derived from global laboratory experiments, aim to strategically manage and prevent the spread of targeted diseases. One prominent strategy involves population replacement, wherein genetically modified mosquitoes are introduced to replace the existing local wild population. To enhance our understanding and aid in the design of effective release strategies, we employ a comprehensive mathematical model. The utilized approach employs agent-based modeling, enabling the consideration of individual mosquito attributes and flexibility in parameter manipulation. Through the integration of an agent-based model and a meta-population spatial approach, the dynamics of gene drive mosquito spreading in a released site are simulated. The model's outcomes offer valuable insights into future population dynamics, providing guidance for the development of informed release strategies.

Foreign direct investment plays an important role in globalization. It is dramatically increasing in the age of globalization. It has played an important role for economic growth in this global process. It can provide new markets and marketing channels, cheaper production facilities, access to new technology, products to a firm. FDI has come to play a major role in the internationalization of business. FDI has become even more important than trade. Growing liberalization of the national regulatory framework governing investment in enterprises and changes in capital markets profound changes have occurred in the size, scope and methods of FDI. New information technology systems, decline in global communication costs have made management of foreign investments far easier than in the past. FDI provide opportunities to host countries to enhance their economic development and opens new opportunities to home countries to optimize their earnings by employing their ideal resources. Smaller and weaker economies can drive out much local competition. For small and medium sized companies, FDI represents an opportunity to become more actively involved in international business activities. In the past decade, foreign direct investment has expanded its role by change in trade policy, investment policy, tariff liberalization, easing of restrictions on foreign investment and acquisition in many nations, and the deregulation and privatization of many industries. In present competitive scenario, FDI has become a prominent external source of finance for developing countries. <p class="card-text"><strong>Keywords:</strong> <a
