The results from these experiments compared with standard ITUR-P empirical models and to reflect the dependence of vegetation attenuation on the input parameters under observation.	Download
2	Numerical Modelling for Investigations of Lip Shock Relating to Fluid Flow over a Backward Facing Rounded Step by Using Hybrid RANS-LES Dr. Nirmal Kumar Kund Abstract - A 2D numerical model is established to study the supersonic turbulent fluid flow over the backward facing rounded step by introducing the hybrid RANS-LES turbulence model, also otherwise termed as the Spalart-Allmaras turbulence model, which includes a viscosity-like working variable. In addition, the model comprises more significant challenges like production, diffusion and destruction terms apart from the very usual issues pertaining to the current investigations. The numerical simulations are conducted with the stated turbulence model with the inflow free stream Mach number of 2.5 accompanied by the free stream pressure and velocity of 15350 N/m2 and 651.9 m/s2, respectively. The simulation predictions with the hybrid RANS-LES model provides reasonably superior and accurate results all over the whole flow region including the wall vicinity region as well, therefore, the said model is used throughout the entire studies. The simulation predictions reveal that the gradual expansion takes place over the rounded step which leads to the delay in viscous layer separation. Certainly, it causes the formation of relatively shorter shear layer along with the fairly shorter recirculation region, approaching towards the dead air region of the bottom wall. In addition, it is quite apparent from the present research that the non-appearance of lip shock over the rounded step. In other words, it is realized that there is termination of lip shock owing to the use of rounded step in place of sharp edge step.	Download
3	Experimental Investigation on Concrete Using Copper Slag as Fine Aggregate with Bacterial Admixture R.Deby Linsha, P.Kaviyarasi, M.Anbalagan Abstract - "With increasing scarcity of river sand and natural aggregates across the country, construction sector is under tremendous pressure to explore alternative to these basic construction material to meeting growing demand of infrastructure demands,"In states like Kerala, Maharashtra and Gujarat, sand mining in rivers has already been banned owing to its disastrous impact on ecology. Therefore, slag has a big potential of being developed as a suitable alternative material to these resources. At present, across the world around 33 ton of slag is generated while in India three copper producers, Birla Copper and Hindustan Copper produce around 6-6.5 tones of slag at different sites.During the smelting operation, iron is removed as iron silicate, which is known commonly known as copper slag (Ferro sand).As per scientific estimate, for every ton of copper metal produced, around 1.8-2.2 tones of slag is generated. In this project tests on concrete is carried out by varying proportions of copper slag and bacteria. The test results show desirable properties such as increase in strength of concrete.	Download
4	Experimental Investigation of Pervious Concrete for Rigid Pavement K. S. Binitha, M. Priyadharshini, M. Ragul Abstract - The project aims at making and studying the different properties of pervious concrete using locally available admixtures in Chennai. Pervious concrete (or) no fineness concrete is a combination of cement and aggregate where the usage of sand is neglected. This type of concrete costs much less than normal concrete. Pervious concrete can be used in Parking areas, Side Pavements, Pedestrian path etc., where load distribution is generally low. Pervious concrete is very much important for future application on pavements for development of water conservation and to reduce water logging. An admixture known as Nano silica is used in our project to increase the strength of the concrete. This pervious concrete allows water to percolate and also this protects streams and lakes and allows local vegetation to thrive. Pervious concrete can be used as pavements or pathway in high rise apartments to increase the ground water and also it can be used in the sides of highway pavements to save run-off water. It gives high strength and permeability when no fines are used. The grade chosen for the investigation is M25.This paper attempt is made to develop the mix design for pervious concrete. The specimen results comparison for conventional concrete and pervious concrete. The graphs are plotted and it shows the variation of results.	Download

Anbalagan Abstract - This paper presents the results of an experimental study conducted to examine the effect of fibre reinforcement on M60 Grade of concrete using ultrasonic pulse velocity and rebound hammer techniques. In this study a total of 32 cubes of size 150x150x150mm were cast and tested using ultrasonic pulse velocity and rebound hammer. The study parameter was the total fibre volume fraction. Variation of pulse velocity and rebound numbers were studied for fibre contents varying from 0% to 1.5%. The fibres had an aspect ratio of 60. It has been found that the compressive strength of concrete increases by about 15-20% for a fibre content of 1%. The UPV measurement and compressive strength tests were carried out at the concrete age of 7, 14 and 28 days. It has been found that the compressive strength of SFRC increases up to 15.31% when compared with the virgin specimen. This increased strength leads to a more ductile concrete.	Download

26	PAPR Reduction in OFDM Systems Using A Piecewise Linear Companding Transform on Cyclic Shift PTS T Suneel Kumar, G. Sreenivasulu Abstract - Orthogonal frequency division multiplexing (OFDM) signals have high peak-to-Average power ratio (PAPR). PAPR is a major drawback in the application of OFDM communication. High PAPR, which causes distortion when OFDM signal passes through a nonlinear high power amplifier and reduce system efficiency. We have various methods for the reduction of PAPR, Among various methods Partial Transmit Sequence (PTS) is best method. A cyclic shifted sequences (CSS) scheme is evolved from the PTS scheme to improve the PAPR reduction performance. In the CSS scheme challenging one is the shift value (SV) set should be carefully selected because those are closely related to the PAPR reduction performance of the CSS scheme. However, as Companding transform is an extra operation after the modulation of OFDM signals, companding schemes reduce PAPR at the expense of increasing the Bit Error Rate (BER). In this paper , a new piecewise linear companding transform is proposed aiming at mitigating companding distortion. With the careful design of the companded peak amplitude and the linear transform scale, the proposed transform can achieve better reducing PAPR effectively.	Download

31	Secure and Efficient Third Party Auditing Scheme for Cloud Data Storage Manibharathi R, Dr.K.Selva kumar, Dinesh R Abstract - Cloud computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. However, the fact that users no longer have physical possession of the possibly large size of outsourced data makes the data integrity protection in Cloud computing a very challenging and potentially formidable task, especially for users with constrained computing resources and capabilities. Existing privacy-preserving public auditing protocols assume the end devices of users are powerful enough to compute all costly operations in real time when the data to be outsourced is given. In fact, the end devices may also be those with low computation capabilities. Thus the proposed system is used for two lightweight privacy-preserving public auditing protocols. 1) TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data, and introduce no additional on-line burden to the cloud user; 2) The third party auditing process should bring in no new vulnerabilities towards user data privacy. The algorithm proposed here is online/offline algorithm. Thus the proposals support batch auditing and data dynamics.	Download
