For the dynamic train movement with four modes of operation, including accelerating mode, constant speed or cruising mode, coasting mode, and braking mode are considered in this study. The acceleration rate, the deceleration rate, and the starting coasting point are taken into account the optimal train speed profile during coasting mode with considering the energy saving and acceptable travel time comparison to the based case with no coasting operation. In this study, the mathematical method as a Quadratic Search Method (QDS) is conducted to carry out the optimization problem. A single train of MRT services between two stations with a distance of 2 km and a maximum speed of 80 km/h is taken to be the case study. Regarding the coasting mode operation, the results show that the longer distance of costing mode, the less energy consumption in cruising mode and the less braking energy. On the other hand, the shorter distance of coasting mode, the more energy consumption in cruising mode and the more braking energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title="energy saving">energy saving</a>, <a href="https://publications.waset.org/abstracts/search?q=coasting%20mode" title=" coasting mode"> coasting mode</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20rapid%20transit" title=" mass rapid transit"> mass rapid transit</a>, <a href="https://publications.waset.org/abstracts/search?q=quadratic%20search%20method" title=" quadratic search method"> quadratic search method</a> </p> <a href="https://publications.waset.org/abstracts/122572/energy-saving-study-of-mass-rapid-transit-by-optimal-train-coasting-operation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122572.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">311</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">4734</span> Theory of Gyrotron Amplifier in a Vane-Loaded Waveguide with Inner Dielectric Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reyhaneh%20Hashemi">Reyhaneh Hashemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahrooz%20Saviz"> Shahrooz Saviz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In his study, we have survey the theory of gyrotron amplifier in a vane-loaded waveguide with inner dielectric material.

From numerical analysis of this dispersion relation, it is shown that the stability behavior of the fast-wave mode is dependent of the dielectric constant. With a small axial momentum spreed, a super bandwidth is shown to be attainable by a mixed mode operation. Also, with the utilization from the numeric analysis of relation dispersion.

The armature winding consists of several independent multiphase windings that have different rating rotate speed and power. Compared to conventional motor, the novel motor structure has more operation mode and fault tolerance mode, which makes it adapt to high-reliability requirement situation such as electric vehicle, aircraft and ship. Performance of novel motor structure varies with winding match. In order to find optimum control strategy, motor torque character, efficiency performance and fault tolerance ability under different operation mode are analyzed in this paper, and torque distribution strategy for efficiency optimization is proposed. Simulation analyze is taken and the result shows that proposed structure has the same efficiency on heavy load and higher efficiency on light load operation points, which expands high efficiency area of motor and cruise range of vehicle.

How to generate economic value based on the environmental capacity is not only an economic decision but also a political decision to make. Boshan took the full use of “Ecology” and transformed it as an inexhaustible green resource to benefit people, reflecting the sustainable value of new agriculture development mode. The Strawberry Harvest Festival and Blueberry Harvest Festival hosted approximately 96,000 and 54,000 leisure tourists respectively in 2014. For the Kiwi Harvest Festival in August 2014, in average, it attracted about 4600 tourists per day, which generated daily kiwi sales of 50,000 lbs and 3 million RMB (About 476,000 USD) of daily revenue. The purpose of this study is to elaborate the modes of agritourism development, by analyzing the cases in rural area of Boshan, China. Interviews with the local government officers were applied to discover operation mode of agritourism operation. The financial data was used to demonstrate the strength of government policy and improvement of the income of rural people. The result indicated that there are mainly three types of modes: the Intensive Mode, the Model Mode and the Mixed Mode, supported by case study respectively. With the boom of tourism, the development of agritourism in Boshan relies on the agriculture encouraging policy of China and the effort of local government; meanwhile, large scale of cultivation and the product differentiation are the crucial elements for the success of rural agritourism projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=agritourism" title=" agritourism"> agritourism</a>, <a href="https://publications.waset.org/abstracts/search?q=economy" title=" economy"> economy</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20area%20development" title=" rural area development"> rural area development</a> </p> <a href="https://publications.waset.org/abstracts/41424/agritourism-development-mode-study-in-rural-area-of-boshan-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41424.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">316</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">4729</span> Mechanical Tension Control of Winding Systems for Paper Webs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Glaoui%20Hachemi">Glaoui Hachemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a scheme based on multi-input multi output Fuzzy Sliding Mode control (MIMO-FSMC) for linear speed regulation of winding system is proposed. Once the uncoupled model of the winding system was obtained, a smooth control function with a threshold was selected to indicate how far away the case was from the sliding surface. nevertheless, this control function depends closely on the higher bound of the uncertainties, which generates overlap. So, this size has to be chosen with broad care to obtain high performances. Usually, the upper bound of uncertainties is difficult to know before motor operation, so, a Fuzzy Sliding Mode controller is investigated to resolve this problem, a simple Fuzzy inference mechanism is used to decrease the chattering phenomenon by simple adjustments. A simulation study is achieved and that the indicate fuzzy sliding mode controllers have great potential for use as an alternative to the conventional sliding mode control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Winding%20system" title="Winding system">Winding system</a>, <a href="https://publications.waset.org/abstracts/search?q=induction%20machine" title=" induction machine"> induction machine</a>, <a href="https://publications.waset.org/abstracts/search?q=Mechanical%20%20tension" title=" Mechanical tension"> Mechanical tension</a>, <a href="https://publications.waset.org/abstracts/search?q=Proportional-integral%20%28PI%29" title=" Proportional-integral (PI)"> Proportional-integral (PI)</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control" title=" sliding mode control"> sliding mode control</a>, <a href="https://publications.waset.org/abstracts/search?q=Fuzzy%20%20logic" title=" Fuzzy logic"> Fuzzy logic</a> </p> <a href="https://publications.waset.org/abstracts/160448/mechanical-tension-control-of-winding-systems-for-paper-webs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160448.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">102</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">4728</span> Modeling the Moment of Resistance Generated by an Ore-Grinding Mill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marinka%20Baghdasaryan">Marinka Baghdasaryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tigran%20Mnoyan"> Tigran Mnoyan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The pertinence of modeling the moment of resistance generated by the ore-grinding mill is substantiated.

Recently, main control valve (MCV) which is composed of several independent metering valve (IMV) has been introduced for better energy efficiency of the hydraulic system so that fuel efficiency of the excavator can be improved. Excavator with IMV has 5 operating modes depending on the quantity of regeneration flow. In this system, the hydraulic pump is controlled to supply demanded flow which is needed to operate each mode. Because the regenerated flow supply energy to actuators, the hydraulic pump consumes less energy to make same motion than one that does not regenerate flow. The horse power control is applied to the hydraulic pump of excavator for maintaining engine start under a heavy load and this control makes the flow of hydraulic pump reduced. When excavator is in complex operation such as loading or unloading soil, the hydraulic pump discharges small quantity of working fluid in high pressure. At this operation, the engine of excavator does not run at optimal operating line (OOL). The engine needs to be operated on OOL to improve fuel efficiency and by controlling hydraulic pump the engine can drive on OOL. By continuous mode changing of IMV, the hydraulic pump is controlled to make engine runs on OOL. The simulation result of this study shows that fuel efficiency of excavator with IMV can be improved by considering engine OOL and continuous mode changing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=continuous%20mode%20changing" title="continuous mode changing">continuous mode changing</a>, <a href="https://publications.waset.org/abstracts/search?q=engine%20fuel%20consumption" title=" engine fuel consumption"> engine fuel consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=excavator" title=" excavator"> excavator</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20efficiency" title=" fuel efficiency"> fuel efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=IMV" title=" IMV"> IMV</a> </p> <a href="https://publications.waset.org/abstracts/89388/energy-efficiency-improvement-of-excavator-with-independent-metering-valve-by-continuous-mode-changing-considering-engine-fuel-consumption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/89388.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">389</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">4726</span> Fuzzy Logic Based Sliding Mode Controller for a New Soft Switching Boost Converter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azam%20Salimi">Azam Salimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Delshad"> Majid Delshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a modified design of a sliding mode controller based on fuzzy logic for a New ZVThigh step up DC-DC Converter .

However, the zero-bandgap feature of the graphene limits its nonlinear optical applications, e.g., saturable absorption for these applications require strong light-matter interaction. Nevertheless, the excellent optoelectronic properties, such as broad tunable bandgap energy and high carrier mobility of Group 10 transition metal dichalcogenides 2D materials, e.g., PtS2 introduce new degree of freedoms in the optoelectronic applications. This work reports our recent research findings regarding the saturable absorption property of PtS2 layered 2D material and its possibility to be used as saturable absorber (SA) for ultrafast mode locking fiber laser. The demonstration of mode locking operation by using the fabricated PtS2 as SA will be discussed. The PtS2/PVA SA used in this experiment is made up of some few layered PtS2 nanosheets fabricated via a simple ultrasonic liquid exfoliation. The operational wavelength located at ~1 micron is demonstrated from Yb-doped mode locking fiber laser ring cavity by using the PtS2 SA. The fabricated PtS2 saturable absorber offers strong nonlinear properties, and it is capable of producing regular mode locking laser pulses with pulse to pulse duration matched with the round-trip cavity time. The results confirm successful mode locking operation achieved by the fabricated PtS2 material. This work opens some new opportunities for these PtS2 materials for the ultrafast laser generation.

The degradation of the cell voltage was 0.015V after such 2500 hrs operation. The degradation rate was therefore calculated to be 6uV / hr.

We propose a semi-parametric approach to estimate the mode of an unknown continuous multivariate density function. Our approach is based on a weighted average of a parametric density estimate using the Box-Cox transform and a non-parametric kernel density estimate. Our semi-parametric mode estimate improves both the parametric- and non-parametric- mode estimates. Specifically, our mode estimate solves the non-consistency problem of parametric mode estimates (at large sample sizes) and reduces the variability of non-parametric mode estimates (at small sample sizes). The performance of our method at practical sample sizes is demonstrated by simulation examples and two real examples from the fields of climatology and image recognition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Box-Cox%20transform" title="Box-Cox transform">Box-Cox transform</a>, <a href="https://publications.waset.org/abstracts/search?q=density%20estimation" title=" density estimation"> density estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20seeking" title=" mode seeking"> mode seeking</a>, <a href="https://publications.waset.org/abstracts/search?q=semiparametric%20method" title=" semiparametric method"> semiparametric method</a> </p> <a href="https://publications.waset.org/abstracts/53756/a-semiparametric-approach-to-estimate-the-mode-of-continuous-multivariate-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53756.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">289</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">4720</span> An Algorithm for Estimating the Stable Operation Conditions of the Synchronous Motor of the Ore Mill Electric Drive</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Baghdasaryan">M.

This natural governor action means that the governor responds with changing megawatt output to disturbances in system frequency. More and more, power system managers are demanding that governors operate with constant megawatt output. One way of doing this is to introduce a second set point in the control structure called a power set point. The control structure investigated and analyzed in this paper is unique in the way that it utilizes a power reference set point in addition to the conventional frequency reference set point. An optimum set of temporary droop parameters derived based on the turbine-generator inertia constant and the penstock water start time for stable islanded operation are shown to be also equally applicable for a satisfactory rate of generator loading during its grid connected mode. A theoretical development shows why this is the case. The performance of the control structure has been investigated and established based on the simulation study made in MATLAB/Simulink as well as through testing the real time controller performance on a 15 MW Kaplan Turbine and generator. Recordings have been made using the labVIEW data acquisition platform. The hydro-turbine governor control structure and its performance investigated in this paper thus eliminates the need to have a separate set of temporary droop parameters, one valid for islanded mode and the other for interconnected operations mode. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=frequency%20set%20point" title="frequency set point">frequency set point</a>, <a href="https://publications.waset.org/abstracts/search?q=hydro%20governor" title=" hydro governor"> hydro governor</a>, <a href="https://publications.waset.org/abstracts/search?q=interconnected%20operation" title=" interconnected operation"> interconnected operation</a>, <a href="https://publications.waset.org/abstracts/search?q=isolated%20operation" title=" isolated operation"> isolated operation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20set%20point" title=" power set point"> power set point</a> </p> <a href="https://publications.waset.org/abstracts/8883/dual-set-point-governor-control-structure-with-common-optimum-temporary-droop-settings-for-both-islanded-and-grid-connected-modes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8883.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">4715</span> Inverse Saturable Absorption in Non-linear Amplifying Loop Mirror Mode-Locked Fiber Laser</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haobin%20Zheng">Haobin Zheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang%20Zhang"> Xiang Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong%20Shen"> Yong Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hongxin%20Zou"> Hongxin Zou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The research focuses on mode-locked fiber lasers with a non-linear amplifying loop mirror (NALM). Although these lasers have shown potential, they still have limitations in terms of low repetition rate. The self-starting of mode-locking in NALM is influenced by the cross-phase modulation (XPM) effect, which has not been thoroughly studied. The aim of this study is two-fold. First, to overcome the difficulties associated with increasing the repetition rate in mode-locked fiber lasers with NALM. Second, to analyze the influence of XPM on self-starting of mode-locking. The power distributions of two counterpropagating beams in the NALM and the differential non-linear phase shift (NPS) accumulations are calculated. The analysis is conducted from the perspective of NPS accumulation. The differential NPSs for continuous wave (CW) light and pulses in the fiber loop are compared to understand the inverse saturable absorption (ISA) mechanism during pulse formation in NALM. The study reveals a difference in differential NPSs between CW light and pulses in the fiber loop in NALM. This difference leads to an ISA mechanism, which has not been extensively studied in artificial saturable absorbers. The ISA in NALM provides an explanation for experimentally observed phenomena, such as active mode-locking initiation through tapping the fiber or fine-tuning light polarization. These findings have important implications for optimizing the design of NALM and reducing the self-starting threshold of high-repetition-rate mode-locked fiber lasers. This study contributes to the theoretical understanding of NALM mode-locked fiber lasers by exploring the ISA mechanism and its impact on self-starting of mode-locking. The research fills a gap in the existing knowledge regarding the XPM effect in NALM and its role in pulse formation. This study provides insights into the ISA mechanism in NALM mode-locked fiber lasers and its role in selfstarting of mode-locking. The findings contribute to the optimization of NALM design and the reduction of self-starting threshold, which are essential for achieving high-repetition-rate operation in fiber lasers. Further research in this area can lead to advancements in the field of mode-locked fiber lasers with NALM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inverse%20saturable%20absorption" title="inverse saturable absorption">inverse saturable absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=NALM" title=" NALM"> NALM</a>, <a href="https://publications.waset.org/abstracts/search?q=mode-locking" title=" mode-locking"> mode-locking</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20phase%20shift" title=" non-linear phase shift"> non-linear phase shift</a> </p> <a href="https://publications.waset.org/abstracts/173606/inverse-saturable-absorption-in-non-linear-amplifying-loop-mirror-mode-locked-fiber-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173606.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">104</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">4714</span> Comparison of Interactive Performance of Clicking Tasks Using Cursor Control Devices under Different Feedback Modes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jinshou%20Shi">Jinshou Shi</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaozhou%20Zhou"> Xiaozhou Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Yingwei%20Zhou"> Yingwei Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuoyang%20Zhou"> Tuoyang Zhou</a>, <a href="https://publications.waset.org/abstracts/search?q=Ning%20Li"> Ning Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi%20Zhang"> Chi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhanshuo%20Zhang"> Zhanshuo Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziang%20Chen"> Ziang Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to select the optimal interaction method for common computer click tasks, the click experiment test adopts the ISO 9241-9 task paradigm, using four common operations: mouse, trackball, touch, and eye control under visual feedback, auditory feedback, and no feedback. Through data analysis of various parameters of movement time, throughput, and accuracy, it is found that the movement time of touch-control is the shortest, the operation accuracy and throughput are higher than others, and the overall operation performance is the best. In addition, the motion time of the click operation with auditory feedback is significantly lower than the other two feedback methods in each operation mode experiment. In terms of the size of the click target, it is found that when the target is too small (less than 14px), the click performance of all aspects is reduced, so it is proposed that the design of the interface button should not be less than 28px.

Low specific Chlorophyll-a content of algae was a strong indicator of light induced stress on algal cells. It was concluded that long term operation of photo bioreactors in the continuous illumination mode was infeasible under the range of incident light intensities examined and provision of a dark period after each light period was necessary for algal cells to recover from light-induced stress. Long term operation of photo bioreactors in the intermittent illumination mode was however possible at light intensities of 0.24 and 2.52 W L-1. Further, the incident light intensity in the photo bioreactors was found to decline exponentially with increase in algal concentration in the reactor due to algal ‘self-shading’. This may be an important determinant for photo bioreactor performance at higher algal concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Algae" title="Algae">Algae</a>, <a href="https://publications.waset.org/abstracts/search?q=algal%20growth" title=" algal growth"> algal growth</a>, <a href="https://publications.waset.org/abstracts/search?q=photo%20bioreactor" title=" photo bioreactor"> photo bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=photo-inhibition" title=" photo-inhibition"> photo-inhibition</a>, <a href="https://publications.waset.org/abstracts/search?q=%E2%80%98self-shading%E2%80%99" title=" ‘self-shading’"> ‘self-shading’</a> </p> <a href="https://publications.waset.org/abstracts/1521/impact-of-light-intensity-illumation-strategy-and-self-shading-on-sustainable-algal-growth-in-photo-bioreactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1521.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">328</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">4712</span> A Study on the Optimal Placement and Control Scheme for Multi Terminal HVDC in Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chur%20Hee%20Lee">Chur Hee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ju%20Sik%20Kwak"> Ju Sik Kwak</a>, <a href="https://publications.waset.org/abstracts/search?q=Seung%20Wan%20Kim"> Seung Wan Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals about economics and control of optimal placement of multi-terminal HVDC in Korea.

Identification of trip mode distribution will allow transportation authorities to adopt appropriate strategies to reduce travel time, traffic and air pollution. The majority of existing trip mode inference models operate based on human selected features and traditional machine learning algorithms. However, human selected features are sensitive to changes in traffic and environmental conditions and susceptible to personal biases, which can make them inefficient. One way to overcome these problems is to use neural networks capable of extracting high-level features from raw input. In this study, the convolutional neural network (CNN) architecture is used to predict the trip mode distribution based on raw GPS trajectory data. The key innovation of this paper is the design of the layout of the input layer of CNN as well as normalization operation, in a way that is not only compatible with the CNN architecture but can also represent the fundamental features of motion including speed, acceleration, jerk, and Bearing rate. The highest prediction accuracy achieved with the proposed configuration for the convolutional neural network with batch normalization is 85.26%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predicting" title="predicting">predicting</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=neural%20network" title=" neural network"> neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20trip" title=" urban trip"> urban trip</a> </p> <a href="https://publications.waset.org/abstracts/123355/an-improved-convolution-deep-learning-model-for-predicting-trip-mode-scheduling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123355.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">142</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">4710</span> The Magnetized Quantum Breathing in Cylindrical Dusty Plasma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Abdikian">A.

By using linear quantum hydrodynamic model, not only the quantum dispersion relation of rotation mode but also void structure has been derived in the presence of an external magnetic field. Although the phase velocity of the magnetized quantum breathing mode is greater than that of unmagnetized quantum breathing mode, attenuation of the magnetized quantum breathing mode along radial distance seems to be slower than that of unmagnetized quantum breathing mode. Clearly, drawing the quantum breathing mode in the presence and absence of a magnetic field, we found that the magnetic field alters the distribution of dust particles and changes the radial and azimuthal velocities around the axis. Because the magnetic field rotates the dust particles and collects them, it could compensate the void structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=the%20linear%20quantum%20hydrodynamic%20model" title="the linear quantum hydrodynamic model">the linear quantum hydrodynamic model</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20magnetized%20quantum%20breathing%20mode" title=" the magnetized quantum breathing mode"> the magnetized quantum breathing mode</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20quantum%20dispersion%20relation%20of%20rotation%20mode" title=" the quantum dispersion relation of rotation mode"> the quantum dispersion relation of rotation mode</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20structure" title=" void structure"> void structure</a> </p> <a href="https://publications.waset.org/abstracts/69938/the-magnetized-quantum-breathing-in-cylindrical-dusty-plasma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69938.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">306</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">4709</span> Working Mode and Key Technology of Thermal Vacuum Test Software for Spacecraft Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Lei">Zhang Lei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhan%20Haiyang"> Zhan Haiyang</a>, <a href="https://publications.waset.org/abstracts/search?q=Gu%20Miao"> Gu Miao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A universal software platform is developed for improving the defects in the practical one.

Indoor environment is very much dependent on the parameters such as temperature, relative humidity and air velocity. But these parameters differ according to the operational modes of the dwellings which include free running, cooling, heating and mixed. Free running mode means no active cooling and heating is used to maintain thermal comfort inside the dwellings. Cooling and heating modes are the active cooling and heating devices being operational. Mixed modes include the combined form of free running, cooling and heating. This review paper analyzes parameters related to the indoor environment, such as temperature, relative humidity, and air velocity, based on the operation modes of the dwellings, and examines how these parameters vary across different operation modes of the dwellings. A systematic search was done in the Scopus database using relevant keywords. A two-phase screening process was used: initial title/abstract review and full-text assessment. Irrelevant articles other than journal paper or in a language other than English were excluded, and relevant articles were analyzed in detail. Data of temperature, relative humidity and air velocity were analyzed in relation to operational modes the dwellings. In FR mode, air temperature, relative humidity and air velocity were in the range of 7.5 - 32.5°C, 20 - 78 % and 0 - 0.89 m/s. In the combined CL, HT and mixed mode, air temperature, relative humidity and air velocity ranged between 1.5 - 31.7°C, 35 - 79 % and 0 - 0.55 m/s. The results indicate that relative humidity and air velocity have a wider range in FR mode compared to the combined CL, HT and mixed modes. However, the air temperature in FR mode has a narrower range than in the combined CL, HT and mixed modes. The temperature range in the combined CL, HT and mixed modes suggest the need for CL and HT devices, which are activated when necessary to maintain comfort, thus demanding more energy. The wide range of relative humidity and air velocity in FR mode imply that occupants may experience drafts or excessive humidity, leading to discomfort and higher energy use as they compensate for these variations. Therefore, incorporating hybrid systems or passive design strategies in dwelling can enhance comfort, reduce energy demand, and promote sustainable, energy-efficient living. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dwellings" title="dwellings">dwellings</a>, <a href="https://publications.waset.org/abstracts/search?q=modes" title=" modes"> modes</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20environment" title=" indoor environment"> indoor environment</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20humidity" title=" relative humidity"> relative humidity</a>, <a href="https://publications.waset.org/abstracts/search?q=air%20velocity" title=" air velocity"> air velocity</a> </p> <a href="https://publications.waset.org/abstracts/198237/a-systematic-review-of-the-indoor-environment-in-dwellings-based-on-modes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/198237.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">13</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">4706</span> A Reconfigurable Microstrip Patch Antenna with Polyphase Filter for Polarization Diversity and Cross Polarization Filtering Operation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lakhdar%20Zaid">Lakhdar Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Albane%20Sangiovanni"> Albane Sangiovanni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A reconfigurable microstrip patch antenna with polyphase filter for polarization diversity and cross polarization filtering operation is presented in this paper. In our approach, a polyphase filter is used to obtain the four 90° phase shift outputs to feed a square microstrip patch antenna. The antenna can be switched between four states of polarization in transmission as well as in receiving mode. Switches are interconnected with the polyphase filter network to produce left-hand circular polarization, right-hand circular polarization, horizontal linear polarization, and vertical linear polarization. Additional advantage of using polyphase filter is its filtering capability for cross polarization filtering in right-hand circular polarization and left-hand circular polarization operation. The theoretical and simulated results demonstrated that polyphase filter is a good candidate to drive microstrip patch antenna to accomplish polarization diversity and cross polarization filtering operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20antenna" title="active antenna">active antenna</a>, <a
