Rajiv Gandhi Institute of Technology, named after the late Prime Minister Sri. Rajiv Gandhi, run by the Government of Kerala, started functioning in 1991. Government started this institution with a view of making it a center for post graduation and research studies. The college is affiliated to the Mahatma Gandhi University Kottayam, Kerala.

This paper describes the fabrication and testing of aluminum alloy MMCs reinforced with fused silica particles cast in sand moulds containing metallic and nonmetallic chills. Fused silica particles of size 50-100 μm were dispersed (3-12 wt.%) into the matrix. The resulting composites cast were tested for their microstructure, strength, hardness, and wear behavior. Microstructural studies indicate good bonding along with uniform distribution of the dispersoid. Strength, hardness and wear resistance increase up to 9 wt.% additions of dispersoid and copper chill was found to be the best because of its high volumetric heat capacity. © 2011 Elsevier Ltd.

Energy is considered a prime agent in the generation of wealth and a significant factor in economic development. Energy is also essential for improving the quality of life. Development of conventional forms of energy for meeting the growing energy needs of society at a reasonable cost is the responsibility of the Government. Limited fossil resources and environmental problems associated with them have emphasized the need for new sustainable energy supply options that use renewable energies. Development and promotion of non-conventional/alternate/new and renewable sources of energy such as solar, wind and bio-energy, etc., are also getting sustained attention. Alternative energy news source has long asserted that there are fortunes to be made from smart investments in renewable energy. Solar power is one of the hottest areas in energy investment right now, but there is much debate about the future of solar technology and solar energy markets. This report examines various ways in which solar power is precisely such an opportunity. © 2010 Elsevier Ltd. All rights reserved. Source

The present paper deals with the dispersion relation preserving (DRP) analysis of the Robert-Asselin type filters coupled with leapfrog time integration method for time dependent non-dispersive and dispersive model systems. As, leapfrog time advancement method is widely used in the numerical modeling of atmosphere and ocean dynamics, despite the fact that in addition to physical mode it also admits a spurious mode. This is the major disadvantage of leapfrog time integration scheme in discrete computing. To suppress the spurious mode associated with leapfrog time integration method, Robert-Asselin type filters are extensively used in the literature. Here, the dispersion analysis is based on the spectral analysis by considering filtered/unfiltered leapfrog time integration method along with spatial discretization schemes. Spatial discretization is performed using second order centered difference and optimized compact schemes. Furthermore, to assess the efficacy of these methods one dimensional convection equation is used as a model equation for the non-dispersive case, while linearized rotating shallow water equations (LRSWE), as a model test problem for the dispersive case. © 2016 Elsevier Ltd.

The growth potential of any state is linked with infrastructure and electricity infrastructure is the most important parameter for economic growth. Maharashtra, a prominent state in India consumes 12 per cent of India's electricity. Maharashtra's power sector is facing the electricity deficit and shortage since early 2005. On the other hand, industrial and service sectors are rising in the state. The present paper discusses electricity situational analysis of the state. Electricity demand analysis has been presented and comparison of state electricity demand vis-à-vis Mumbai's demand (state capital) has been carried out for two years. Variation for monthly average demand for two years and load shedding have also been analyzed. Power supply situation analysis and analysis of major power suppliers have been carried out. The State Load Distribution Center data is used to depict the load variation for a typical day. Interventions needed to sustainably meet the growing demands are also discussed. © 2012 Elsevier Ltd.

This paper presents a multilevel inverter topology suitable for the generation of dodecagonal space vectors instead of hexagonal space vectors as in the case of conventional schemes. This feature eliminates all the $6n harmonics from the phase voltages and currents in the entire modulation range with an increase in the linear modulation range. The topology is realized by flying capacitor-based three-level inverters feeding from two ends of an open-end winding induction motor with asymmetric dc links. The flying capacitor voltages are tightly controlled throughout the modulation range using redundant switching states for any load power factor. A simple and fast carrier-based space-vector pulsewidth modulation (PWM) scheme is also proposed for the topology which utilizes only the sampled amplitudes of the reference wave for the PWM timing computation. © 1986-2012 IEEE.
