Comparative study of renewable energy based stills and electric heater coupled stills for water purification
Water scarcity is the major problem that calls for the development and economy of the country. One of the best and most inexpensive methods to solve those problems were by solar distillation method. The productivity of the still depends upon many parameters. Expect water temperature other parameters cannot be altered. In this work sensible heat storage material; latent heat storage material was used along with biomass boiler and electric heaters to increase the water temperature in the still. An external glass cooling method was used to reduce the losses and increases the condensation rate in the still. Naturally available biomass such as wood was tried in this work as biomass fuel. Experiments are carried out by coupling various still designs such as the pyramid, multi-basin and single basin design with the biomass boiler and elecrtic heater. The single basin still was operated in the solar mode for comparison. Payback periods are calculated for various stills, the payback periods for biomass augmented stills are low when compared to solar stills and stills coupled with the heater. The multi-basin still with electric heater produces more yield than other shapes of design. The percentage of productivity for single basin still was 59% more than single basin solar still,66% more than pyramid still and 72% more in multi-basin still.

Design, development and experimental studies of downdraft gasifier
Fossil fuels are the major source of energy but the quantities of these are limited and use of these causes greenhouse effect by net addition of CO2 to earth atmosphere and also there is an issue of scarcity of fossil fuels (i.e. Petrol, LPG, and CNG) in the world. Especially in developing country like India, fossil fuel price is also very high. So, current objective is to find a substitute for a fossil fuel. Before the existence of fossil fuel, biomass was the only source of energy which was understood by mankind and utilized as a fuel. Gasification of biomass allows overcoming these issues. Energy extraction from biomass with considering environmental aspect is a challenge. Gasification is thermochemical process which converts biomass into synthesis gas (“syngas”). Syngas mainly comprises of Hydrogen (H2) and Carbon Monoxide (CO), which has the capability to further burnout and releases energy. Syngas can be used for power production, heating application, and liquid fuel production. There are several reactors available for gasification process; present study is focused on downdraft gasifier reactors. It is focused on the production of syngas and effect of various parameters like equivalence ratio, the moisture content of biomass wood used on a composition of syngas. Therefore, the intention is to produce a substitute gaseous fuel syngas from biomass by using fixed bed downdraft gasifier.

SDR-based portable satellite tracking device
SDR (Software Defined Radio) Based Portable Satellite Tracking Device(PSTD). It is a research-based project based on satellite tracking and thereby creating a network of satellite ground stations which is purely focused on observing and tracking of satellite signals. The deployed ground stations can either create a global network and can automatically schedule and accomplish a target satellite. The obtained data is hosted on a web server. When completed it becomes India’s first active SDR Based Portable Satellite Tracking Device which provide the data to SATNOG community. The SDR Based Portable Satellite Tracking Device client area (which has a raspberry pi or Linux pc) and signal reception region which consist of commercial rotator or satellite DIY rotator which is used for controlling antennae rotation. The signal reception region consists of SDR region and signal amplification unit. The antennae may be stationary/omnidirectional and directional. The main advantages are it focuses on receiving LEO satellite signals, US’s NOAA, the hardware, and software are open sources, SDR enabled RF front end for maximum flexibility, data from the deploying ground station are uploaded on cloud for easy access, web support for observation scheduling on ground station with LOS with the target.

Simulation and implementation of FPGA based image processing algorithm
Image preprocessing system is growing towards high speed, high-resolution, high integration, and high-reliability. Image processing systems are widely applied in military and commercial areas. Subsequently, In the military fields the detection of objects based on image processing technology has become a major research topic its interference immunity and noncontact and concealment objects detection New technology has been enhanced in the world due to the increase in new image processing technology. In the commercial sector, it is widely used in machine vision and industrial detection systems. In general, there are 3 types of image processing systems to implement digital image processing algorithms and each system's main chips are ASIC (Application specific integrated circuit), DSP (Digital Signal Process Chip) and FPGA (Field Programmable Gate Array. In this article, we have designed an FPGA-based image processing system. This system can digitize the data stream from the camera and then digitize it, converting digital signals to analog signals. In recent years, microelectronic technology and large scale integrated circuit manufacturing technology development, specifically FPGA, provide new ideas and methods to improve the performance of the image processing system hence it has more advantages compared to ASIC and it has a great demand in the market. Due to large-amount data and fast-processing speed-required for low-level speed image preprocessing, FPGA based image processing system is well-used in image preprocessing. Results show that FPGA-based image processing is suitable for image preprocessing. System simulation is performed using Xilinx ISE design Suite 14.1. The system is implemented using the Xilinx Spartan-6 XC6SLX45 FPGA with Verilog Hardware Description Language.

Analysis on effect of ball burnishing processes of EN24 Steel
In the quality assurance of machine components, the so-called finishing and super finishing processes have important roles. During recent years, the post-machining cold forming methods such as burnishing, shot peening and others have occupied a very important place in the industry. Burnishing, which is one of the effective methods used to improve the surface layer properties, is essentially a cold forming process in which the raised micro-irregularities on the surface layer are plastically moved and pressed into the microcavities. The process is carried out with a highly polished ball or roller type tool which is traversed by force over a rotating workpiece. Machines normally used for burnishing operation can be drill presses, lathes, boring machines, and automatic bar or chucking machines. The process of burnishing can be done on parts which are turned, bored, reamed or ground. Any ductile or malleable material with hardness less than 40 HRC can be successfully burnished. Although diamond burnishing machines are available for finishing material harder than 40 HR. the burnishing process is used to improve the shape of components besides producing a good surface finish. Quite the opposite, the burnishing tool will not correct deviations from roundness or Straightness to any degree. In this work, an attempt is made to compare the results of ball burnishing (in abrasive paste conditions). The parameters taken into consideration are burnishing speed, burnishing feed, burnishing force, ball material and number of passes. Mathematical models have been developed in terms of surface roughness and surface hardness for ball burnishing process.
