Abstract:- Now days, Ad-hoc network play an important role in our daily lives because of their extensive capability of uses in various fields. Mobile Ad-hoc Networks (MANETs) are very popular network with large number of users and due to development of large scale ad-hoc network; scalability has been one of the issue we need to concentrate.A wide variety of industrial processes involve the transfer of heat energy. Throughout any industrial facility, heat must be added, removed, or moved from one process stream to another and it has become a major task for industrial necessity. Heat transfer performance of liquids is limited by their low thermo-physical properties compared with those of solids. The primary reason behind adding solid particles less type of fluid is called a Nano fluid. Dispersing solid metallic or non-metallic materials in a base fluid (liquid), such as water, ethylene glycol or glycerol, has become an interesting topic.

Authors:- M.Tech. Scholar Subhash Chandra Sah, Asst. Prof. Suresh Kumar Badholiya, Prof. Rohit Choudhary
Abstract:- The results revealed that the nano fluid (Ag/HEG) with highest concentration of volume 4% has the highest friction factor at all Reynolds numbers. This solution provides promising ways for engineers to develop highly compact heat exchangers and automobile radiators. When adding nano particles to the base fluid, such as water, the potential enhancement of car engine cooling rates could entail more engine heat being removed or a reduction in size of the cooling system. Smaller cooling systems would lead to smaller and lighter radiators, which would benefit almost every aspect of car performance and increase fuel economy.

Authors:- M.Tech. Scholar Kamlesh Amrute, Prof. Brijendra Kumar Yadav
Abstract:- The steam condenser is one of the important components in a power plant which significantly affect the power generation and performance of unit in terms of heat rate. Deterioration in thermal performance of condenser not only affects the power generation but also thermal performance of unit as a whole. The parameters that are responsible for condenser thermal performance are cooling water (CW) mass flow rate, temperature, heat transfer area, velocity, tube fouling, partially filled water box and air leakage.CW flow rate and condenser pressure changes according to the variation in unit load. The CW temperature at condenser inlet varies according to change in annual temperature cycle of the intake system. During operating condition, the condenser performance is subject to change with variation in exhaust steam and CW parameters. The operating conditions of steam surface condenser are of the great influence on the power generation and the turbine cycle heat rate. At the same time, the operating conditions of the CW system determine the operating condition of the condenser.

A Review on CFD Analysis of Effects of Convergence and Divergence Angles on the Performance of a Nozzle
Authors:- M.Tech. Scholar Vishwajeet Yadav, Prof. Pawan Kumar Tiwari
Abstract:- The convergent – divergent nozzle is the most common type used in rocketry and it works by converting pressure energy from the fuel flow and heat energy from the combustion of fuel into kinetic energy in the form of high exhaust velocity. In the converging section of a rocket nozzle, the exhaust is travelling at relatively low speed (sub-sonic) and it becomes sonic at throat. The compressible exhaust increases until it reaches the exit and it is supersonic in the divergent section. Size and shape of a rocket nozzle is also very important. the converging section starts at the combustion chamber is usually shaped in a way to make sure that flow is not disrupted in any way i.e., the convergence is not too steep and has no harsh edges. Therefore in this paper a review will be done based on research work conducted by scholars.

Abstract:- Now-a-days, the natural fibers and fillers from renewable natural resources offer the potential to act as a reinforcing material for polymer composites alternative to the use of glass, carbon and other man-made fibers. Among various natural fibers and fillers like banana, wheat straw, rice husk, wood powder, sisal, jute, hemp etc. are the most widely used natural fibers and fillers due to its advantages like easy availability, low density, low production cost and satisfactory mechanical properties. For a composite material, its mechanical, physical, wear and water absorption behaviour depends on many factors such as fiber content, orientation, types, length etc. Attempts have been made in this research work to study the effect of different natural fillers loading on the physical, mechanical, wear and water absorption behaviour of glass fiber/natural fillers reinforced polyester based hybrid composites. A hybrid composite is a combination of two or more different types of fibre in which one type of fibre balance the deficiency of another fibre or filler. Composites of various compositions with four different fillers loading (5 wt%, 10wt% and 15wt%) and glass fiber loading is constant (20 wt%) with constant matrix material (polyester resin) are fabricated using simple hand lay-up technique. Different natural fillers which used in present research work are chopped banana, rice husk, wheat straw, and wood powder fillers. It has been observed that there is a significant effect of filler loading on the performance of glass fiber/natural fillers reinforced polyester based hybrid composites. TOPSIS a multi-criteria decision making approach is also used to select the best alternative from a set of alternatives.

Authors:- M.Tech. Scholar M.Bharathi, Asst. Prof. Ms. K. Monica, Asst. Prof. Mr. Degala. Dhana Sekhar
Abstract:-This paper introduces a less power and powerful area shift register utilising pulsed latches. The range and power loss are decreased by interchanging flip-flops by pulsed latches. This technique determines the timing problem among pulsed latches by the advantage of many non-extension limited pulsed clock signals instead of the usual single pulsed clock signal. The shift register (SR) applies a little number of the pulsed clock signals by classifying the latches to many sub-shifter registers and applying additional volatile storage latches. A 128-bit shift register (SR) applying pulsed latches was invented utilising a 65nm CMOS method with VDD = 1.0V. The advanced shift register reserved area and power related to the standard shift register with flip flops.

Abstract:- In this paper we present a blind low recurrence watermarking plan on dark level pictures, which depends on DCT change and spread spectrum interchanges strategy. We process the DCT of non covering 8×8 squares of the host picture; at that point utilizing the DC coefficients of each square we develop a low-goals estimate picture. We apply square put together DCT with respect to this estimation picture, at that point a pseudo irregular clamor arrangement is included into its high frequencies. For recognition, we extricate the estimation picture from the watermarked picture, at that point a similar pseudo arbitrary commotion grouping is created, and its connection is processed with high frequencies of the watermarked guess picture. In our technique, higher strength is gotten due to implanting the watermark in low recurrence. What’s more, higher intangibility is picked up by dispersing the watermark’s bit in various squares. We assessed the power of the proposed system against numerous basic assaults, for example, JPEG compression, added substance Gaussian commotion and middle channel. Contrasted and related works, our strategy end up being profoundly safe in instances of compression and added substance commotion, while protecting high PSNR for the watermarked pictures.

Authors:- Mostafa Abdelshafy Ramadan, Mohamed Hemida Abd-Alla, Usama M. Abdul-Raouf
Abstract:- Bioelectricity production from wastewater beside treatment is the main goal offered by microbial fuel cells (MFCs) technology. This study was demonstrated to evaluating the electricity generated by the double-chamber air-cathodic MFC while reducing pollutants from sugar industry wastewater (SIW). A simple double-chamber MFC was configured with Nafion 117 membrane, and operated without adding any chemical mediators. SIW used as an electron donor and was fed in batch-mode into the MFC for three consecutive operational cycles. While the maximum MFC output voltage in open circuit (OCV) mode was 890 mV after 24 operational days, the closed circuit voltage (CCV) was 340 mV when 550 ohm as external load was applied. From the polarization curve, the maximum power density of 160.16 mW/m2 as power output was observed at a current density of 320.9 mA/m2. The efficiency of the MFC was measured based on columbic efficiency (CE) and chemical oxygen demand (COD) removal rate. While the CE was 46%, the COD removal efficiency reached 85.4%. The anodic biofilm was observed through scanning electron microscopy (SEM). The current study results indicated that SIW microbial communities in the anodic biofilm have the ability to produce bioelectricity using MFC in parallel with the SIW substrate treatment.
