International Journal of Emerging Electric Power Systems Design of HVDC and SVC Coordinate Damping Controller Based on Wide Area Signal

HVDC and FACTS devices have been widely applied in power system for their excellent and flexible control ability. Their contributions to the damping of system oscillations are of great importance for achieving satisfactory system performance. However, previous experience has shown that there may be negative interactions among FACTS devices whose supplementary controllers are designed separately. This may deteriorate system performance and even make system unstable. The interactions of HVDC and SVC during system oscillation were analyzed in this paper. The coordinate supplementary damping controller for HVDC and SVC were then designed based on projective control principle. The criterion of synthetic residue is adopted in choosing the proper input wide area signals. Eigenvalue analysis and time domain simulations were performed on a two-area system and the results demonstrated the effectiveness of the proposed controller.
IPO Intra Industry Effects on Peer Firm's Earnings, Composition and Stock Returns

The present study is conducted to see how an IPO event affects the existing firm's performance within the same industry. For this purpose, 88 IPO firms were examined from Pakistan Stock Exchange (PSX) from 1998-2016. IPO is examined from three major perspectives IPO proceeds, initial returns and time Lag between IPO listing date and IPO subscription. The study uses Buy and Hold Abnormal Returns (BHAR) and Cumulative Abnormal Returns (CAR) to calculate competitor's abnormal returns. To calculate the operating performance of competitors, the Wilcoxon significance test was applied. IPO intra-industry effects are significant in the long run, whereas insignificant results are shown in the short run. In addition, IPO proceeds and abnormal returns are significant but negatively related to competitors' stock returns (long term). Moreover, Herfindahl Hirschman Index (HHI) finds IPO improves competitiveness in the industry environment. This present study is an important one from an emerging economy perspective.

A review of research on the distribution, ecology, behaviour, and conservation of the Slender Loris Loris lydekkerianus (Mammalia: Primates: Lorisidae) in India

The Slender Loris in India includes two subspecies, the Mysore Slender Loris and the Malabar Slender Loris, with unidentified populations at overlapping ranges of the subspecies. Prior to 1996, the knowledge on Indian lorises was mostly limited to laboratory studies, or some anecdotes from the wild. Since late 1990, several intensive field studies have been carried out which informed about the status, ecology, behaviour, conservation issues, and management of the Slender Loris in India. Here, we review all these studies, discuss the major findings and identify directions for future research.

Numerical Study on Proton Exchange Membrane Fuel Cell with 2mm×2mm and 25cm2 Serpentine Flow Channel

As fossil fuels are becoming less reliable and more costly, the Proton Exchange Membrane Fuel Cell (PEMFC) is emerging as the primary candidate to replace the stationary and transport applications. In this study numerical simulation on PEMFC is done by commercially available Computational Fluid Dynamics (CFD) software. A three-dimensional, model of a single PEM Fuel cell with serpentine flow field design has been used for the study. The numerical model is 3-D steady, incompressible, single phase and isothermal includes the governing of mass, momentum, energy, and species along with electrochemical equations. All of these equations are simultaneously solved in order to get current flux density and H2, O2 and H2O fractions along the flow field design.
Relational Positioning Method for 2D and 3D Ad Hoc Sensor Networks in Industry 4.0

Industry 4.0, or smart factory, refers to the fourth industrial revolution, as a result of which it is expected that massive sensor deployment, high device connectivity, automation, and real-time data acquisition support improve industrial processes. Sensor fault detection and operator tracking allow adequate performance of the sensor network supporting Industry 4.0, and sensor localization has become crucial to enable sensor fault detection. Hence, the development of new localization methods is necessary for environments where GPS localization technology is unfeasible. Furthermore, position location information (PLI) is a crucial requirement for the deployment of multiple services and applications in wireless ad hoc and sensor networks supporting Industry 4.0. Three-dimensional (3D) scenarios are considered to extend the applicability of PLI-based services. However, PLI acquisition presents several challenges within any 3D ad hoc sensor network paradigm. For instance, conventional triangulation algorithms are often no longer applicable due to the lack of direct land-fixed references and the inclusion of a third-dimension coordinate. In this paper, a PL relational searching algorithm suitable for 2D and 3D ad hoc environments was formulated in terms of a discretized searching space and a vertex weight assignment process according to distance relationships from anchor nodes to the node to be located on a feasibility space. The applicability of the proposed algorithm was examined through analytic formulation and simulation processes. Results show small distance errors (less than 1 m) are achievable for some scenarios.
Challenges in managing complex chronic middle ear disease: MERF experience

Background: Chronic otitis media is one of the commonest conditions managed in otolaryngology practice. In developing countries such as India, advanced disease presentation is often seen mostly owing to lack of awareness of the disease and its potential complications, long distance between the patient’s home and the treatment centre, causing delay in treatment. Surgical management is the mainstay of treatment of chronic otitis media.Methods: The aim of this study was to retrospectively analyze the patients with complex chronic middle ear disease, who underwent tympanomastoid surgery. Forty-seven patients (4.9%) out of a total of 968 patients with chronic otitis media presented with complex advanced disease and challenging intra-operative situations at our tertiary referral centre between January 2016 to December 2020. The extent of disease, associated complications, challenges in surgical management, and the eventual outcomes were studied in detail.Results: Among these forty-seven patients, there were 24 males and 23 females. Of the 47 patients, 8 were children (17%). Extensive cholesteatoma causing facial palsy, labyrinthine fistula, dural involvement, internal auditory meatus involvement, extensive granulations extending into the inner ear through the oval or round window, extensive tympanosclerosis was noted in these patients. All patients underwent surgical management, and achieved satisfactory outcomes.Conclusions: Advanced chronic otitis media has the potential to pose various challenges during tympanomastoid surgery. Appropriate planning for surgery aiming at complete disease clearance, meticulous after-care and long-term surveillance result in favorable outcomes.
Study on Energy Saving by Means and Potentiality of Hybrid Wheel Loader with Energy Materials

Based on the characteristics of high fluctuation and periodicity of output power during working process of wheel loader, hybrid drive technology can provide a solution for fuel saving and fuel reduction of wheel loader through power adjustment function and energy recycle feature. Aiming at power output motion of wheel loader duty cycle, 7 means for hybrid wheel loader to save fuel have been proposed; contribution to save fuel and easiness to realize the goal under current technical conditions of each means has also been assessed. It is considered that there are two categories of wheel loader energy saving technology: one is to increase fuel utilization rate, and the other is improve transmission efficiency of torque converter. However, realizing one of these two aspects can not save fuel ideally; improvement in both aspects will bring satisfactory energy materials saving effects.
Instructional Leadership and Role of Module Leaders

Leadership plays an important role in an educational establishment as they help to manage the day-to-day activities. Instructional leadership has always played a distinct role in higher education as the role of instructional leadership was always to influence on effective teaching and learning processes. The purpose of this research is intended to identify the role of instructional leadership, including the relationship between instructional leadership and the role of module leaders in higher education using their own institution as a case study. The author conducted a small scale semistructured interview where two programme leaders were selected from the School of Business and Health and Social Care and were approached directly by sending formal email and also over the phone and asked if they were willing to participate. Research findings suggest that instructional leadership enables the programme/module leaders to establish a shared belief around the learning and can improve the learner’s achievement.
Total-dose radiation hardness assurance

Total-dose radiation hardness assurance is reviewed for MOS and bipolar devices and integrated circuits (ICs), with an emphasis on issues addressed by recent revisions to military and commercial standard test methods. Hardness assurance typically depends upon sample tests of a subgroup of devices or circuits to determine whether the full group meets its performance and functionality requirements to a desired confidence level. The dose rates of many standard test methods match neither the very high dose rates of some military environments nor the very low dose rates of most space environments. So, one must ensure that hardness assurance test plans address device response in the radiation environment of interest. An increasing emphasis has been placed over the last few decades on standardized test procedures to qualify devices for use in the natural space radiation environment. Challenging issues for defining test methods for space environments are nMOS transistor threshold-voltage rebound and enhanced low-dose-rate sensitivity for linear bipolar devices and ICs. Effects of preirradiation elevated temperature stress on MOS radiation response are also a significant concern. Trends are identified for future radiation hardness tests on advanced microelectronics technologies.
Analysis and minimization of ripple components of input current and voltage of PWM inverters

Analysis and minimization of the ripple components of the input current and voltage of three-phase voltage-source PWM inverters are presented in this paper. The analytical expressions for the RMS values of the input current and voltage ripples as a function of the shape of the PWM reference signal are derived. It is found that the reference signal which produces a minimum ripple in the input voltage varies as a function of the load power factor. It is also found that the RMS value of the inverter input current ripple does not depend on the shape of the reference signal. In respect of the inverter input current and voltage ripples, the addition of harmonics other than the third into the sinusoidal reference is neither useful nor necessary. Experimental results are included to verify the derived expressions.

Characteristics and Success Factors of Rural Community Leadership in Malaysia: A Focus Group Analysis

INTRODUCTION Today’s society is continuously confronted with demanding a leader develop strategies for achieving structured goals (Podsakoff et al., 2018). A leader is a person who controls or commands a group, organisation, or country. Leadership is the art of influencing and directing people to their obedience, confidence, and loyal cooperation in achieving common objectives (Gandolfi & ABSTRACT The leadership aspects of rural leaders in Malaysia are still unclear, and a consensus of the characteristics of credible rural community leaders has not been achieved. In addition, there is still a lack of specific and in-depth research on community leadership in rural areas in Malaysia. Therefore, a study was conducted to deepen understanding of leadership, specifically in the rural community leadership characteristics and success factors. The current study used a qualitative approach via a focus group discussion method involving 15 informants from the Village Development and Security Committee (JPKK) to gain indepth information. The major themes that emerged from findings include inborn leadership, leadership quality, leadership characteristics, leadership motivation, and leadership training, referred to as leaders’ success factors. The current study hopes that the government can provide focused and comprehensive leadership training programs to ensure leaders perform their duties effectively and efficiently.
Theoretical and experimental validation of a generalized Wheeler cap method

Although Wheeler's method has been reported as being one of the most accurate for the measurement of the radiation efficiency of antennas, its limitations are also known: it assumes that the antenna can be modelled as a RLC circuit; the losses resistance must appear in series with the radiation resistance; no cavity resonances can be present within the bandwidth to be measured. To overcome these limitations, an improved method, that treats the antenna as a two-port network, is thoroughly investigated here by electromagnetic simulation. After the method is validated, two cylindrical cavities, meant to be used in the measurement of the radiation efficiency of small printed antennas, are designed, fabricated and tested. Two different aspects of the cavities are investigated: the presence of cavity resonances and the cavity quality factor. (6 pages)
Markov characterization of digital fading mobile VHF channels

We apply techniques for the modeling of error sequences on digital communication channels to results of experiments undertaken on mobile VHF channels. The experiments were carried out using four different modulation schemes at some of the different standardized signaling rates. The modulation schemes used were: FSK @ 300 baud, DPSK @ 1200 baud, QPSK @ 1200 baud, and 8-ary PSK @ 1600 baud, and in each case, subcarrier modulation was used. The experiments were undertaken for urban as well as freeway environments. Fritchman-partitioned Markov chain models were derived throughout, and from the models, block error probability distributions were derived. These block error probability distributions or P(m,n) give the probability that a block of n bits will contain exactly m errors. We present P(/spl ges/m,n) for 7-, 15-, 31-, 63-, 127-, and 255-b blocks, for the above-mentioned modulation schemes, in the mobile VHF environments mentioned. P(/spl ges/m,n) denotes the probability that at least m errors will occur in a block of n bits. Furthermore, the P(/spl ges/m,n) information presented here, should give some indication of the performance to be expected from block error-correcting schemes. >
Formation and Computation of Relationship in Complex Social Networks

Social networks provide customs with a platform for interaction and information sharing. In real social activities, whether individuals or businesses, have to rely on some relations to live, work or engage in commercial activities. The formation of relationship between different actor clusters based on the same actor in real social networks is described in the paper. The relationships and their types as well as relationship attributes in real complex social networks are analyzed in details. An index called Qinshudu to represent the degree of closeness between two actors in real complex social networks is proposed and its computation model based on relationship types and attributes etc. are given. Case study shows that Qinshudu is a very reasonable and effective way for the use of complex social networks.
Dynamic aberration correction for an optical see-through head-mounted display

The object of this paper is to present the experimental validation of aberration compensation into a novel design for seethrough head-mounted displays. The proximity of the user's head generates high geometrical constraints. To compensate for the resulting aberrations, we use both dynamic sequential image creation and dynamic adapted aberration compensation. The see-through head-mounted display is composed of a holographic mirror serving as a combiner and a phase modulation spatial light modulator which insures the dynamic phase correction. The first step of the work has consisted in the realization of the holographic combiner and the characterization of the phase modulation by the light modulator. An experimental analysis of the aberrations of the image beam has been conducted. Next, the implementation of the theoretical corrective phase function into the spatial light modulator has been realized. Finally, the experimental demonstration of the expected aberration compensation has been achieved.
Method for electrical detection of bond wire lift-off for power semiconductors

A novel approach is presented for detecting bond wire lift-off in power semiconductor devices while they are in operation. The aim is to improve the reliability of power electronic systems. The method comprises a specific bond assembly and an integrated subcircuit as part of the gate driver, and serves to detect bond wire lift-off in parallel switched power devices, a typical end-of-life phenomenon encountered in modules, which results in loss of contact and therefore of controllability. The former is detected and the system is prevented from going abruptly into failure mode, so that the destruction of devices is safely avoided.
Intermodulation distortion in pseudomorphic HEMTs and an extension of the classical theory

Pseudomorphic high electron-mobility transistors (pHEMTs) offer superior RF and microwave performance and, in particular, exhibit exceptional intermodulation distortion characteristics that are not adequately modeled by the classical theory. Intermodulation products are typically 8-10 dB below classical expectations, and can be as much as 12 dB lower. An extension of the classical theory is presented, which allows for a better understanding of this phenomenon in terms of the device transconductance characteristic. Experimental data is included to provide quantitative verification based on both device and amplifier results. pHEMT-based devices have the potential to satisfy the spectral performance requirements of today's wireless systems with improved dc-to-RF efficiencies.
A Project-based Undergraduate Aerospace Sequence, with Embedded Computational Intelligence

century students must be adept with systems and software. Given pressure to maintain four-year degree programs, many Universities have restricted their initiatives to technical electives and fostered the development of extra-curricular student teams; at best programs have introduced one new software or project-based course while maintaining legacy requirements nearly as they were decades ago. This paper examines a series of courses, currently electives, that if adopted into the required curriculum can offer Aerospace students exposure in each undergraduate year to progressively more advanced computing theory/practice in the context of motivational project- based activities. We focus on a series of project activities in use at the University of Michigan aimed at giving students a "fundamental" understanding of the Aerospace system and its software we hope will ultimately approach the level of understanding students have traditionally gained in mathematical and physics-based concepts.
