Abstract:  Data deduplication is one of important data compression techniques for eliminating duplicate copies of repeating data, and has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the confidentiality of sensitive data while supporting deduplication, the convergent encryption technique has been proposed to encrypt the data before outsourcing. To better protect data security, this paper makes the first attempt to formally address the problem of authorized data deduplication. Different from traditional deduplication systems, the differential privileges of users are further considered in duplicate check besides the data itself.We also present several new deduplication constructions supporting authorized duplicate check in hybrid cloud architecture. Security analysis demonstrates that our scheme is secure in terms of the definitions specified in the proposed security model. As a proof of concept, we implement a prototype of our proposed authorized duplicate check scheme and conduct testbed experiments using our prototype. We show that our proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.

Abstract: Chlorophyll and Nitrogen are related to each other. Estimating one will give content of other. Many techniques are invented to estimate these two. Remote sensing, hyperspectral data, multi spectral imaging data, vegetation indices, light absorbance technique are some of the estimation techniques. Some tools also used say, RapidEye, QuickBird, MODIS sensor, SPAD meter, CCM 200 meter. These techniques are divided in two categories- Non destructive and Destructive. However, Image processing technique is proving to be effective among all these; which come under non destructive method. In this paper, some of these techniques are reviewed.

Keywords: Estimation techniques, Non-destructive, Image processing.

Abstract: The increasing risk of global warming by greenhouse gasses requires further development of renewable energy sources. Sharp escalation in prices and fast depletion of conventional energy sources leads to search for an alternative energy. Microbial fuel cell technology is a new type of renewable and sustainable technology for electricity generation.  It recovers energy from materials that are difficult to dispose of such as sugar waste water, municipal waste water, dairy waste water and paper industry waste water. Biological hydrogen production processes are found to be more environment friendly and less energy intensive.

Microbial fuel cells are electrochemical device used for converting chemical energy contained in organic matter into electricity by means of catalytic (metabolic) activity of living microorganisms. It is an alternative method to reduce cost of treatment and generate electricity. Microbial source uses dairy waste water as a substrate for the production of electricity. Microbial fuel cells have an advantage over other electricity production methods because of their high efficiency. Some experimentation was carried out by using waste water from various sources and urine as microbial fuel cell feed. Using Proton exchange membrane as electrolyte open circuit voltage of 0.46V with waste water and 0.42V using urine waste was observed.

Keywords:  Renewable energy, Microbial fuel cell, electricity generation, electrolyte, waste water, urine.

Abstract: SS316L stainless steels have been widely used in highly corrosive environments for power generation, chemical, fertilizer, marine, food, oil and gas industries and petrochemical reactors. These materials are well known for their good corrosion resistance and mechanical properties like strength etc. However, because of its low hardness and wear resistance their applications are greatly limited .The Austenitic steel has an Austenitic structure is stable at ambient temperature and characterized by the presence of chromium and nickel and low carbon content Austenitic steels are used in various aggressive environments and at high and low temperatures. The most common heat treatment for all types of austenitic steel is solution annealing. Research is going on over years to reduce the wear either in the form of using a new wear resistant material or by improving the wear resistance of the existing material by addition of any wear resistant alloying element etc. In this paper an study has been made to review few of the methods of improve the properties like wear, corrosion and hardness on austenitic stainless steel SS316L.

Keyword: SS316L, Wear, corrosion, hardness.

Abstract: This paper represents the analysis of 6 stage Dickson charge pump. The aim is to compare the current, efficiency, voltage of Dickson charge pump using either diodes or MOSFET’s as diodes. This paper presents the suitable criteria for properly sizing the capacitors according to clock signals, which allows the charge pump performance to be optimized. A six-stage Dickson charge pump was designed to produce a 7.36 V output from a 1.2V supply, using 250 kHz, two-phase non-overlapping clock signal driving the charge pump.

Keywords: high voltage DC output; DC-DC converter; charge pump; single clock charge pump; Dickson charge pump.

Abstract: In this paper we are discussing about the Wind Tunnel and its types. The Wind Tunnel Testing Machine is used in Aerodynamic research to study the effects of Air moving past to the solid objects. This paper we discuss the Design, Construction and Testing process open circuit low speed wind tunnel. The Design of wind tunnel is very important to proper working and accuracy of result. The construction process is depending on Design parameters and quality of material. In the testing we use the pitot tube, manometer and solid object (airfoil). Solid object is representing the original shape of the object. The testing chamber is main part of wind tunnel. We calculate the velocity of fluid and drag & lift forces. It is use to experimental analysis of object. Experiment conducted after build to find drag coefficient of a shape. An impression of fluid field flow around a shape is using air. 

Keywords: Open Circuit Wind Tunnel, Single Testing Section, Wind Tunnel Design, Industrial Design, airfoil analysis.
