Computer science (CS) is defined in wikipedia as a branch of human knowledge “relating to computation, ranging from abstract analysis of algorithms and formal grammars, to subjects like programming languages, software, and computer hardware” (Computer Science, 2005). Computer science emerged as a distinct field in the 1940s and 1950s with the development of the first electronic digital computers. To limit computer science to just computer use or its knowledge bodies, however, is reductive; CS is embedded in a complex, unquantifiable cultural context, including socio-economic and gendering practice. Computer hardware and software are designed to complement and supplement human activity and processes such as warfare, industrial applications, information management, including education, the Internet, a knowledge commons, and most recently biotechnology. Although CS is typically considered neutral and scientific, its episteme and practice is androcentric or male centered, often to the exclusion of females (Herbst, 2002). Female attributes have not typically been associated with computer science or computers. Although there is general agreement that women are as intellectually capable as men in CS, the fact remains that women today do not have equal participation in CS majors, CS engineering, programming, software design, Web site construction, or computer repair. (Jepson & Perl, 2002). In the technetronic 21st century, when computers are becoming standard for education and in symbolic analytic jobs, women’s enrollment in CS has declined, and many women do not feel confident using computers for more than e-mail transmissions, e-commerce, and social interaction in forums or newsgroups. Women who do not have knowledge or confidence in their abilities to work in CS not only have unrealized potentials in CS but also are left out of employment activities. Reasons for gendering in CS are complex and debated. Socialization, overt and tacit discrimination, and epistemological plurality are three dominant explanations. CS industries, educators, cognitive scientists, parents, and women professionals in CS are some of the groups currently working to attain gender equity in CS.

Power electronics play a fundamental role for electric transportation, renewable energy conversion and many other industrial applications. They have the ability to help achieve high efficiency and performance in power systems. However, traditional inverters such as voltage source and current source inverters present some limitations. Consequently, many research efforts have been focused on developing new power electronics converters suitable for many applications. Compared with the conventional two-stage inverter, Z-source inverter (ZSI) is a single-stage converter with lower design cost and high efficiency. It is a power electronics circuit of which the function is to convert DC input voltage to a symmetrical AC output voltage of desired magnitude and frequency. Recently, ZSIs have been widely used as a replacement for conventional two-stage inverters in the distributed generation systems. Several modifications have been carried out on ZSI to improve its performance and efficiency. This paper reviews the-state-of-art impedance source inverter main topologies and points out their applications for multisource electric vehicles. A concise review of main existing topologies is presented. The basic structural differences, advantages and limitations of each topology are illustrated. From this state-of-the-art review of impedance source inverters, the embedded quasi-Z-source inverter presents one of the promising architectures which can be used in multisource electric vehicles, with better performance and reliability. The utilization of this new topology will open the door to several development axes, with great impact on electric vehicles (EVs).

Statistical Process

Functional data appear in a multitude of industrial applications and processes. However, in many cases at present, such data continue to be studied from the conventional standpoint based on Statistical Process Control (SPC), losing the capacity of analyzing different aspects over the time. In this study is presented a Statistical Control Process based on functional data analysis to identify outliers or special causes of variability of harmonics appearing in power systems which can negatively impact on quality of electricity supply. The results obtained from the functional approach are compared with those obtained with conventional Statistical Process Control that has been done firstly.

Harmonic Study

Power system harmonics may cause several problems, such as malfunctions of electrical equipment, premature equipment failures and plant shutdowns. Accordingly, mitigation of these harmonics is considered an important target especially for industrial applications where any short downtime period may lead to great economic losses. Harmonic analysis studies are necessary to analyze the current and voltage harmonic levels and check if these levels comply with the contractual or international standard limits. If the studies reveal that the preset limits are exceeded, then a suitable harmonic mitigation technique should be installed. Harmonic analysis studies in the industrial electrical systems are discussed in many references. However, a comprehensive procedure for the steps required to perform a harmonic study is rarely found in the literature even though it is strongly needed for design engineers. This paper provides a comprehensive procedure for the steps required to perform a harmonic study in the form of a flowchart, based on industrial research and experience. Hence, this paper may be considered as a helpful guide for design engineers and consultants of the industrial sector.

Efficient Power

The 21st century world is more dependent on electrical power than ever. This dependency will increase manifold in the near future with more systems being computerized and a plethora of new electronic devices emerging for household, commercial and industrial applications. In such a scenario, availability of secure, reliable and efficient power is crucial for sustaining current development and economic growth trends. India is struggling to meet electric power demands of the fast expanding economy. In this situation, “smart grid” is the only solution, as it provides an open platform for electricity market and power transactions and offers high quality service and optimizes resource allocation. Simply stating smart grid refers to the application of information technology to power systems. Due to the complexity of such systems, the possibilities have yet to be clearly defined. Undertaking smart grid research in India is necessary for safe and stabilization of national power grid, optimization of national energy structure etc. This paper explores the definition, characteristics of smart grid and the gap between today’s grid and smart grid and its milestones are analyzed. Also the necessity of smart grid and enormous challenges which Indian power enterprises are facing is analyzed through which the inspiration of developing smart grid in India can be gained. Finally some of the ongoing smart grid activities in India and the barriers to implement the smart grid are discussed. The power system development as the world’s new trend of change, smart grid will lead the Indians to restore confidence, revive industry and promote sound and fast economic growth.
