Optimal allocation of multi-type FACTS Controllers by using hybrid PSO for Total Transfer Capability Enhancement
Authors: Chansareewittaya Suppakarn , Jirapong Peerapol 
Published: April 2020

In this paper, the new hybrid particle swarm optimization (hybrid-PSO) based on particle swarm optimization (PSO), evolutionary programming (EP), and tabu search (TS) is developed. Hybrid-PSO is proposed to determine the optimal allocation of multi-type flexible AC transmission system (FACTS) controllers for simultaneously maximizing the power transfer capability of power transactions between generators and loads in power systems without violating system constraints. The particular optimal allocation includes optimal types, locations, and parameter settings. Four types of FACTS controllers consist of thyristor-controlled series capacitor (TCSC), thyristor-controlled phase shifter (TCPS), static var compensator (SVC), and unified power flow controller (UPFC). Power transfer capability determinations are calculated based on optimal power flow (OPF) technique. Test results on IEEE RTS 24-bus system, IEEE 30-bus system and, IEEE 118-bus system indicate that optimally placed OPF with FACTS controllers by the hybrid-PSO could enhance the higher power transfer capability more than those from EP and conventional PSO.

Published: April 2020

The paper presents a new control strategy and design for auxiliary energy source (AES) used in battery hybrid electric vehicle (BHEV) based on the acceleration power. The control strategy takes actual speed and acceleration of the vehicle and system losses into account for regulating the energy and power supply to the propulsion load. The design of AES and its dynamic control design are demonstrated. Cascade control is availed in this work in order to control the terminal voltage and current of supercapacitors (SCs). The benefits of AES in which recapture of regenerative braking energy are examined by the numerical simulation and verified by a small scale experiment. The comparison of energy consumption and DC bus voltage regulation between pure battery and battery with supercapacitors (BSCs) propulsion system declares the theoretical results and confirms the benefits of the proposed method.
Impact of high WPPs penetration on the Vietnam Power System
Authors: Nguyet Nguyen Hanh Thi , Vittal Vijay 
Published: April 2020

Wind power installed capacity is expected to reach 1,000 MW and 6,200 MW in the Vietnam Power System (VPS) in 2020 and 2030, respectively. But detailed dynamic analysis of the wind power plants’ (WPPs) integration into the VPS is still scarce. In this paper, first, the impact of WPPs’ integration on the dynamic voltage performance and the wind turbine generator (WTG) low-voltage-ride-through (LVRT) requirement in the VPS for the year 2020 is studied. Then, case studies on the VPS for the year 2020 with different levels of wind penetration and different values of WTG’s maximum allowable voltage sag are studied. Simulation results show that the 2020 VPS can lose as much as 1,000 MW (100%) of WPP’s generated power following a severe contingency if the WTG’s LVRT capability is not considered. In some scenarios, the loss of WPPs’ generated power can cascade into a power system islanding situation which in turn could cause massive load shedding (15%) in the load-rich subsystem and result in wide variations of the electrical parameters of generators near the islanding boundary.
Studying Peripheral Vascular Pulse Wave Velocity Using Bio-impedance Plethysmography and Regression Analysis
Authors: Huang Ji-Jer , Huang Yang-Min , See Aaron Raymond 
Published: April 2020

In this study, a simple bioimpedance plethysmography method was employed to measure the pulse wave velocity (PWV) from the radial artery in the wrist to the middle finger of a patient. Subsequently, electrocardiography was combined with a bioimpedance method to calculate the PWV from ECG and pulse waves to the middle finger. Experiments were conducted by employing cuffs that temporarily block blood flow to produce observable changes in the PWV. Statistical results indicated that temporary blockage of blood flow did not influence the PWV of typical healthy people. Moreover, multiple regression analysis was used to establish an equation for estimating two types of PWV and their relevance with other physiological parameters. Multiple regression analysis indicated that the abdomen circle and height are independent predictors of the PWV from the radial artery in the wrist to the middle finger (wfPWV) (r = 0.893). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) are independent predictors of the PWV from the EGC T wave to the middle finger (tfPWV) (r = 0.898). Correlation analysis showed the wfPWV is significantly associated with tfPWV (r = 0.770, p < 0.01).
An Efficient Search Algorithm for Multi-hop Network Localization in a Sparse Unit Disk Graph Model
Authors: Kaewprapha Phisan , Tansarn Thaewa , Puttarak Nattakan 
Published: April 2020

We consider a network localization problem by modeling this as a unit disk graph where nodes are randomly placed with uniform distribution in an area.The connectivity between nodes is defined when the distances fall within a unit range. Under a condition that certain nodes know their locations (anchor nodes), this paper proposes a heuristic approach to find a realization for the rest of the network by applying a tree search algorithm in a depth- first search manner. Our contribution is to put together a priori information and constraints such as graph properties in order to speed up the search. An evaluation function is formed and used to prune down the search space. This evaluation function is used to select the order of the unknown nodes to iterate. This paper also extends the idea further by accommodating a variety of other properties of graphs into the evaluation function. The results show that node degrees, node distances and shortest paths to anchor nodes drastically reduce the number of iterations required for realizing a feasible localization instance both in noise-free and noisy environments. Finally, some preliminary complexity analysis is also given.

Authors: Mufungulwa George , Tsutsui Hiroshi , Miyanaga Yoshikazu , Abe Shin-ichi 
Published: April 2020

In any real environment, noises degrade the performance of Automatic Speech Recognition (ASR) systems. Additionally, in the case of similar pronunciations, it is not easy to realize a high accuracy of recognition. From this point of view, our work envisions an enhanced algorithm processing a speech modulation spectrum, such as Running Spectrum Analysis (RSA). It was also adequately applied to observed speech data. In the envisioned method, a modulation spectrum filtering (MSF) method directly modified the observed cepstral modulation spectrum by a Fourier transform of the cepstral time frequency. The method and experiments carried out for various passbands had favorable results that showed an improvement of about 1-4 % in recognition accuracycompared to conventional methods.
Pattern Based Motion Estimation using Zero Motion Pre-judgement and Quantum behaved Particle Swarm Optimization
Authors: Patnaik Yogananda , Patra Dipti 
Published: April 2020

Motion estimation is a fundamental and resource hungry operation in most of the video coding applications. The most popular method used in any video coding application is block matching motion estimation (BMME). This conventional fast motion estimation algorithm adopts a monotonic error surface for faster computation. However, these search techniques may trap at local minima resulting in erroneous motion estimation. To overcome this issue, various evolutionary swarm intelligence based algorithms were proposed. In this paper, a pattern based motion estimation using zero motion prejudgment and Quantum behaved Particle Swarm Optimization (QPSO) algorithms is proposed, referred to as the Pattern Based Motion Estimation (PBME) algorithm. The notion of QPSO improves the diversity in the search space, which enhances the search efficiency and helps in reduction of the computational burden. At the same time, QPSO needs fewer parameters to control. Therefore, the proposed algorithm enhances the estimation accuracy. An initial search pattern (Hexagonal Based Search) was used which speeds the convergence rate of the algorithm. From the simulation results, it was found that the proposed method outperformed the existing fast block matching (BMA) algorithms of the search point reduction by 40–75%
Similarity Score Estimation and Gaps Trimming of Multiple Sequence Alignment for Phylogenetic Tree Analysis
Authors: Damkliang Kasikrit , Tandayya Pichaya , Sangket Unisa , Pasomsub Ekawat 
Published: April 2020

Phylogenetic tree analysis is a process for finding the highest possible revolution tree history of an interested organism. The important step of the process is multiple sequences alignment (MSA) which is operated using any MSA tool that produces a result in blocks of the Phylip format. Bioinformaticians have to manually determine and trim gaps of the MSA blocks using relevant tools of a software package in the off-line mode. The data blocks need to be manually cut-and-pasted between these tools. This working steps tend to be error-prone and time consuming. In addition, improper algorithm selection for tree inferring without applying an MSA similarity score tends to generate the phylogenetic tree with low accuracy and also take much more time. In this work, we present a new practical approach for the phylogenetic tree analysis applying our enhancement for the similarity score estimation and gaps trimming of the MSA blocks. We propose \textit{in-silico} algorithms for automating the concerned similarity score estimation and gaps trimming, and deploy them as web services. We demonstrate the web services utilized by composing them into an integrated stateful WSDL workflow. Our case study datasets are a complete coding sequences (CDS) and sets of complete genome of Dengue Viruses - 2, fetched from the NCBI RefSeq nucleotide database. Our proposed algorithms have correctly returned results, verified and satisfied by our bioinformaticians. Our distributions, user manuals and endpoints of the web services, and the open source programs are available at https://bioservices.sci.psu.ac.th.

This paper proposed the new algorithm intended to solve a specific real-world problem, the symmetric travelling salesman problem. The proposed algorithm is based on the concept of the galaxy based search algorithm (GbSA) and embedded the new ideas called the clockwise search process and the cluster crossover operation. In the first step, the nearest neighbor algorithm introduces to generate the initial population. Then, the tabu list local search is employed to search for the new solution in surrounding areas of the initial population in the second step. The clockwise search process and the cluster crossover operation are employed to create more diversity of the new solution. Then, the final step, the hill climbing local search is utilized to increase the local search capabilities. The experiments with the standard benchmark test sets show that the proposed algorithm can be found the best average percentage deviation from the lower bound.

Authors: Tsarenko I. V. 
Published: April 2020

Article is devoted to a search for an optimal format of blended distance learning. The questioning of distance learning students of Sukhoi State Technical University of Gomel was used as a main research method. One discipline from the academic learning program was studied using e-learning technology (on-line classes) whereas (while) others disciplines were studied using traditional classroom face-to-face learning technique. Thus, students using blended distance learning have opportunity to compare and estimate efficiency together with advantages of both educative techniques. On-line classes were held in the period between sessions using BigBlueButton program.It was found that student majority estimate blended distance learning as most efficiency learning technique; half of questioning students consider that the quality of face-to-face and on-line learning is equal. The main advantages and disadvantages of e-learning were analyzed. Highest student attendance of on-line classes between sessions in comparison with face-to-face classes during session time was found. Optimal amount of disciplines for on-line learning to organize blended distance learning were established. Best regime, time and intensity for on-line classes were determined. Results of these investigations may be useful to organize optimal format of blended distance learning as well as to choose subjects for on-line learning and to create comfortable schedule of distance classes.

Assessment of Critical Convection and Associated Rotation States in Models of Sun-like Stars Including a Stable Layer
Authors: Takehiro Shin-ichi , Brun Allan Sacha , Yamada Michio 
Published: April 2020

Abstract
Recent numerical simulations of rotating stellar convection have suggested the possible existence of retrograde (slow equator, fast poles) or so-called antisolar differential rotation states in slowly rotating stars possessing a large Rossby number. We aim to understand whether such rotational states exist from the onset of convective instability or are the outcome of complex nonlinear interactions in the turbulent convective envelope. To this end, we have made a systematic linear analysis of the critical state of convection in a series of 15 numerical simulations published in Brun et al. We have assessed their degree of supercriticality and most-unstable mode properties, and computed the second-order mean zonal flow response. We find that none of the linear critical cases show a retrograde state at the onset of convection even when their nonlinear counterparts do. We also find that the presence of a stably stratified layer coupled to the convectively unstable upper layer leads to interesting gravity-wave excitation and angular momentum transport. We conclude that retrograde states of differential rotation are probably the outcome of complex mode–mode interactions in the turbulent convection layer and are, as a consequence, likely to exist in real stars.

Les « architextes » encodés dans les logiciels et plateformes industriels ont engagé une mainmise sur la forme du texte. À l’heure actuelle, les grandes entreprises interviennent de plus en plus dans l’écriture des contenus textuels – nouvelle mainmise qui se matérialise dans les processus d’auto-complétion et d’écriture prédictive du « computexte ». Certaines tactiques élaborées par la littérature numérique d’avant-garde ont anticipé cette mainmise sous une forme dystopique : elles ont culminé dans des textes que seules les machines peuvent lire. Des expérimentations récentes sur les réseaux sociaux inversent les paradigmes des avant-gardes historiques. Émergent des crypto-langages qui déjouent de l’intérieur les processus d’exploitation de la langue par la machine tout en rétablissant la communication avec le sujet humain.
