Application of multilevel inverters for higher power purposes in industries has become more popular. This is partly because of high-quality output waveform of multilevel inverters in comparison with two level inverter. In this paper, initially a new topology for sub multilevel inverter is proposed and then series connection of the sub multilevel inverters is proposed as a generalized multilevel inverter. The proposed multilevel inverter uses reduced number of switching devices. The validity of the proposed multilevel inverter is verified with computer simulations using matlab, simulink.Keywords

Land use change modelling are the tools to support timely and effective monitoring of natural resources through spatio-temporal land use/land cover (LULC) change detection which can help decision makers for optimum resources planning and utilisation for sustainable rural development. Number of models and approaches have been developed in recent past to analyse land use/land cover change considering different type of data/variables at different levels of complexity and resolution. Such different methods/ models have their own limitations, advantages and suitability in a particular condition. There is no agreement among research community about suitability and effectiveness of a particular method. Present study aims to present a comparative study of popularly used LULC change detection models and techniques. Different models and techniques are compared in terms of level of complexity, considered explanatory variables, spatial extent, temporal dynamism,predictability and level of spatial interaction. For each category, a thorough review of models and approaches is presented which helps in understanding the operational concepts and utility of models/ approaches.Keywords

The present study was carried out to develop im-proved crop yield estimates for rice and wheat crops through the Empirical Best Linear Unbiased Predic-tion (EBLUP) procedure via the Fay–Herriot area level model at sub-district level in Hisar district. Village-wise crop cutting data and auxiliary remote sensing data (satellite imaginaries) derived from the MODIS Vegetation Indices (MOD13Q1) version 6 were used for model construction. It is noteworthy that the coef-ficient of variation of the developed EBLUP estimates was below 10% for almost all sub-districts. The study revealed a significant enhancement in the efficiency of the yield estimator in comparison to the direct estima-tor, which recommended that with the use of remote sensing data together with crop cutting experiment data, crop yield estimates can be obtained on a small-er scale than the district using existing crop cutting experiments in the district.Keywords
