AC Servo motors have applications in precise positioning like ROBOT, high speed performance & many more. For controlling AC servo motor most of the drive is equipped with traditional controller which may be of PI or PID type. Therefore the tuning of PI parameter used in this drive is very necessary. However, during some operating conditions, this controller may not givesatisfied perforcemance...
While most of the literature on Black men prescribe to a deficit model that focuses on academic failures and poverty, this work focuses on the positive by profiling Black men who have successfully entered information technology (IT) majors. Here we reveal various capitals, their accumulation, and their effects using Bourdieu's framework to inductively uncover that Black men succeed in IT careers by...
The proliferations of social media in enterprises have opened up new opportunities, but at the same time it has also raised new work and workplace related concerns and challenges, such as increased job stress, lack of clear personal and professional boundaries, role conflict, and information misuse. These challenges associated with the new ways of work, if unresolved, could adversely affect the organizations...
Interferometry is well established technique for measuring particle velocity in shock wave physics experiments, where velocity information is encoded as the phase of a periodically varying intensity pattern. Conventional phase stepping technique by using a pair of quadrature signals cannot resolve rapid velocity changes and sub-fringe phenomena accurately in most of the velocimetry data. In this report...
Considerable research has been conducted in the area of Communities of Practice (CoP) over the past two decades. This concept, introduced and popularized Brown and Duguid (1991), has been applied in practice and has formed the basis of numerous scholarly articles. This paper takes a small step towards reviewing the extant literature on CoPs, focusing only on empirical papers. We use the following...
Voltage sag is one of the major power quality problem which results in a failure or a mis-operation of end use equipments. Sensitive industrial loads and Utility distribution networks all suffer from various types of outages and service interruptions which can cost significant financial loss per incident. The aim therefore, is to recommend measures that can improve voltage sag. In this paper a method...
This paper describes conventional and advanced methods for the control of D-STATCOM. The mathematical model of conventional double loop control, Direct-Output-Voltage (DOV) control, Decoupled DOV, Fuzzy-PI and Decoupled Fuzzy-PI based control is studied. The control scheme for the above approaches is implemented using Matlab Simulink platform. The dynamic response of the models are presented and compared.

Information technology (IT) consulting is a job where performance is multidimensional and difficult to measure objectively, and where organizational cultures are often “up or out.” Thus, a consultant will typically be judged by (implicit) comparison to an observer's mental picture of a “top performer.” Three linked studies conducted at a large IT consulting firm examine the nature and implications...
