In this Paper, high resolution methods, such as Multiple Signal Classification (MUSIC), Root MUSIC and Estima-tion of Signal Parameter via Rotational Invariance Technique (ESPRIT) are discussed that model the data as the output of a linear system driven by white noise, and then attempt to estimate the parameters of that linear system. The comparison of the amplitude, power (squared amplitude) and frequency estimation error, based on Matlab simulations is carried out in order to analyse the performance of MUSIC, RootMUSIC, ESPRIT methods in estimat-ing amplitude, power (squared amplitude) and frequency estimation of synthetic power signal both in clean and noisy conditions. Simulation results are presented on signal using mean square error (MSE) as the evaluation criterion. The variation of amplitude, power (squared amplitude) and frequency estimation are compared with respect to data sequence length and Signal to noise ratio (SNR) and their influences on MSE that demonstrate the performance of the high resolution methods are provided. Also the influences of different estimation methods on MSE are compared.

Vapour pressure is the most encouraging innovation for meeting all the cooling and refrigeration needs around the entire world. It is a develop innovation yet its ecological effects remain a worldwide issue. VC's refrigerants, for example, hydrochloroflurocarbons (HCFC) and hydroflurocarbons (HFC) are a noteworthy wellspring of nursery discharges, and a dangerous atmospheric deviation potential (GWP) of these toxins is high 1000 times than CO2. So there is a critical need to build up an option high proficient cooling innovation that is moderate for the commercialization and environment inviting as well. Thermo-elastic cooling framework is among one of the option advances, and have exhibited promising execution potential on the material level. We exhibit that thermo-elasticcooling; a sort of cooling system which depends on the inert warmth of reversible marten-sitic change can have a coefficient of execution up-to 11, with a specifically measured ∆T up-to 17K. The execution of thermo-elastic cooling cycle utilizing Ni-Ti (Nitinol) composite was assessed based upon an adaptable model created in this study. It was found that the general framework COP was 1.53 for a standard case considering both driving engine and pump control utilizations, while COP ran from 5.2 to 7.7 when assessed with future enhancements. This new idea of separating cooling by pressing a strong state shape memory compound has pulled in individuals' consideration since it is an exceptional and new idea and does not depend upon fluorinated liquids. Thermo-elastic cooling framework has shown its potential for cooling in view of its better idle warmth than other focused advancements. The idea of thermo-elastic cooling framework is a feasible and ecological neighbourly cooling choice yet it is still in an early innovative work arrange. With the more research endeavours and upgrades to be carried out in future, this fresh out of the plastic new cooling innovation could be utilized as a part of our homes and workplaces.

The quantification of evaporation losses is essentially carried out for systematic planning and management of irrigation system for draught prone area. Direct and indirect methods are popularly adopted for measurement of evaporation. In case of minor irrigation projects, it is challenging and unaffordable to setup, operate and maintain meteorological monitoring systems. Forecasting tools will be helpful in such minor irrigation projects. A fuzzy computing technique will be one of the significant tools to forecast the evaporative losses. In the present paper a fuzzy approach for forecasting evaporation losses of Makani Reservoir, Osmanabad (MS); India has been carried out. The parameters; temperature, wind speed, and humidity are considered. Linguistic variables are utilized to define input variables and output ranges. An evaporation loss is forecasted by taking into consideration a database for the year 2004 to 2014. A rule base system is adopted for greater precision. The validation is carried out for the next successive years.

Solar energy is received from sun can be converted into useful energy in the form of heat energy. One of the most efficient method water is heated using solar flat plate collector. This heated water can be used for domestic as well as industrial applications. The efficiency of collector depends with many parameters such as area of the collector, number of glass cover, wind velocity and overall top heat loss coefficient. To reduce top loss heat transfer coeffi-cient and improve heat transfer the conventional solar flat plate collector has modified with double glazing ar-rangements. The modified solar collector has installed at a latitude angle of 12 degree facing towards north-south directions. The experiments were carried out in thermosyphon principle from 10:00 to 16:00 hrs. The results show that over all top loss heat transfer coefficient has marginally reduced and collector efficiency 68% obtained. The flow pattern also studied using CFD analysis
