Media: Intensifying the quandaries of Dalit Woman
No full textMedia a fast tracking police van has taken out an excellent step to uplift the social condition of Dalit Woman. Besides broadcasting and penning words on their social and economical condition it has also become a satellite to telecast the physical assault for which they are exploited and drawn out from their community. This paper will come across each and every aspect of media intensifying the problems of dalit woman throughout ages giving an exclusive account of media and its sources in building out a historic change in their life. Instances of everyday discrimination are quite ubiquitous, but they are frequently documented with focus and in- depth coverage in India‘s as well as in other countries‘ mainstream news media. Media has started uploading videos illustrating contributions of the grass-roots level activists and also wrapping various issues concerning the Dalits, Adivasis, Bahuians, Muslims and other minorities etc. As a source, it is only media giving a chance to speak. It has provided an excellent platform to render violence against dalit woman as the outcome of severely imbalanced social, economic and political power equations and widespread exploitation and discrimination in terms of power relations to men in a patriarchal society, as also against their communities based on caste. This paper scrutinizes how media has made these women an instrument through which the social system replicates itself and systemic inequality is maintained. Violence against Dalit women is systematically utilized to deny their opportunities, choices and freedoms at multiple levels, undermining not only Dalit women‘s dignity and self-respect, but also their right to development
Modeling of SEPIC Fed PMBLDC Motor for Torque Ripple Minimization
No full textBLDC Motor suffers from commutation torque ripple, which mainly depends on stator winding impedance, speed and transient line current in the conduction interval. This paper describes a novel circuit topology and a dc input link voltage control strategy to keep incoming and outgoing phase currents changing at the same rate during commutation interval. A SEPIC (single-ended primary inductor converter) and a switch selection circuit are employed in the front of the inverter. The desired commutation voltage is obtained by the SEPIC converter. The input dc link voltage control strategy is carried out by the switch selection circuit to separate two procedures, adjusting the SEPIC converter and regulating speed. The commutation torque ripple is analyzed, and introduced the way to obtain the desired dc link voltage in detail. Finally, simulation and experimental results show that, compared with conventional and the proposed method can obtain the desired voltage is obtained and minimize commutation torque ripple more efficiently
MIMO-TDCS Channel Capacity Enhancement Using Coupling Compensation and Butler Matrix
No full textMIMO-TDCS is a highly promising technique among all capacity enhancement techniques in MIMO system that are existing today. It has considerably magnified channel capacity as compared to the other techniques. But when the coupling between adjacent closely spaced elements of antennae at receiver or transmitter side is considered, capacity decreases. Thus, corresponding compensation is done at transmitter or receiver or at both sides and an improvised method of coupling compensation technique with MIMO-TDCS is born. It provides better channel capacities than pure MIMO-TDCS. When Butler matrix-TDCS combination is introduced, capacity improvements not as good as in former case are obtained. Here, angle domain processing is preferred over conventional array domain processing technique. Lastly, the existing microwave beamforming network technique of Nolen matrix is compared to the above developed techniques and Nolen matrix technique is found to be least efficient
Bridgeless PFC Cuk Derived Converter Fed BLDC Motor with PID and Fuzzy Logic Controller
No full textA bridgeless single phase ac-dc rectifier based Cuk derived converter topology fed BLDC motor is proposed to improvepower factor at the AC mains near to the unity with low THD for PFC applications. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as classical Cuk topology. The partial elimination of diodes in DBR in the bridgeless topology results in lower conduction losses as compared with conventional Cuk converter. The proposed method is simulated in MATLAB/Simulink with PID and fuzzy logic controller for precise speed control. Simulation results are presented along with the theoretical analysis.

Securities Management and Compliances – An Umbrella Mechanism to Ensure Better Corporate Governance in Securities Market
No full textThe Indian economy has consciously shifted from a controlled one to a market driven one. In the process, several developments have unfolded. Indian corporates need to assimilate these developments in order to survive and flourish amidst global competition. They can aspire to reach their goals with success if they pursue the right means. Good governance is the means to that end. Corporate governance extends far beyond the confines of corporate law. The quality, quantity and frequency of financial disclosures, the extent of exercise of fiduciary responsibilities and duties by the boards towards shareholders and stakeholders, accountability and transparency in corporate functioning for maximizing shareholders, wealth are the progressive elements and indeed the underlying spirit of corporate governance. Corporate governance today is a strategic necessity where focus is on quality of governance. Capital and investments from international investors are available to corporates demonstrating good governance practices and thus helping them both in procuring capital at competitive rates and also in employing and retaining the intellectual capital
Fuzzy Based Energy Management Algorithm For Plug In Hybrid Electric Vehicles
No full textThis paper proposes an intelligent workplace parking station for plug-in hybrid electric vehicles (PHEVs) charging. The system consists of smart power charging controller, a 100-kW photovoltaic (PV) panel, DC bus and an utility grid. Stochastic models of the power that is demanded by PHEVs in the parking station and the output power of the PV Panel are presented. In order to limit the impact of the PHEVs’ charging on the utility ac grid, a fuzzy logic power-flow controller was designed. Fuzzy logic controller will predict the charging priority level of PHEVs depending on their power requirements. The charging rates depend on the predicted PV output power, the power demand by the PHEVs and energy price from the utility grid. The developed system can significantly limit the impact of PHEVs on the utility grid and reduce the charging cost. The system architecture and the developed PHEV smart charging algorithm are described. Moreover, a comparison between the impact of the charging process of the PHEVs on the grid with and without the developed smart charging technique is presented and analyzed
