Performance of Strip Footing On Slope Stabilized With Piles
The present paper is the study of the performance of strip footing placed on sandy slope stabilized with a number of rows of piles at various locations. The parameters such as a number of pile rows and location of pile rows are varied. The length of piles, the diameter of piles, the spacing between two adjacent piles in a row and setback distance of strip footing were kept constant. The study revealed that provision of rows of piles along the slope improves the bearing capacity of strip footing. The bearing capacity increases as the number of rows of piles increases.

A Modular Feedforward Phase/Frequency Detector Design for High Speed PLL
Phase Frequency Detector (PFD) is convert the input analog signals into digital output by comparing both input signals in terms of phase and frequency. PFD is widely used in Phase lock loop (PLL) as a phase detector. This paper describes a fully functional modular Feedforward phase/frequency detector and to show the characteristics and behaviour of some PFD designs in order to improve some important aspects as the delay time and the power consumption in the classical model. Circuits are design using 180nm TSMC CMOS technology.

Performance Evaluation of Modified Clipping and Filtering Method for PAPR Reduction
For providing high data-rate offerings over wireless channels, Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) gadget had been proposed in the latest beyond. This gadget affords the advantages of space-time coding and OFDM, when its miles mixed with area time coding. The MIMO-OFDM gadget also suffers from the excessive peak-to-average power ratio (PAPR) trouble. This happens due to the inter-symbol interference between the subcarriers of the communiqué system. Through the use of clipping and filtering the entire look for the number of sub-blocks and the rotation elements should be done, if you want to achieve top-rated PAPR discount. As the number of sub-blocks and rotation factors will increase, PAPR reduction improves. Because the quantity of sub-blocks will increase, the range of calculation additionally will increase. This case ends in growth the complexity exponentially which ends up inside the technique put off. PAPR reduction is collectively optimized in both the real and imaginary element by means of the use of Fast Fourier Transform (FFT) algorithm inside the modified Clipping and filtering scheme. In this work, a modified clipping and filtering approach is offered. This approach is combined with interleaving for PAPR reduction using Quadrature Phase Shift Keying Modulation (QPSK). The main objective of this technique is to keep away from the usage of any greater IFFTs and enhance PAPR reduction. Cumulative Distribution feature (CDF) of PAPR has been taken as an output parameter. The value of this parameter is plotted with respect to PAPR for present and modified techniques. MATLAB R2013a has been used as an implementation platform. Generalized MATLAB toolbox and wireless communication Toolbox has been used for implementation.

Comparative Study of Low Cost Adsorbents in the Elimination of Methylene Blue Dye from Aqueous Solutions
Textile industries consume large volume of water and chemicals for wet processing of textiles. As a result, produce large volumes of colored (dye) water as waste. The effectiveness of adsorption for dye removal from wastewaters has made it an ideal alternative to other expensive treatment options. The present study gives the preliminary experimental results using low cost adsorbents viz; plantain flower petals, banana peels, snake gourd seeds, and egg shell in the eliminating methylene blue dye from aqueous solutions. The effect of various factors on the adsorption of the dye was studied in batch mode which includes pH, concentration of adsorbent and dosage of adsorbents. The study revealed that plantain flower petals were very effective in the removal of methylene blue dye and about 99.7 % removal of dye was observed.

Impact of Attacks on Permutation Only Image Encryption Scheme
Permutation is a commonly used primitive in multi- media (image/video) encryption schemes, and many permutation-only algorithms have been proposed in recent years for protection of multimedia data. In permutation-only image ciphers, the entries of the image matrix are scrambled using a permutation mapping matrix which is built by splitting and shuffling the part of the image. The literature on the cryptanalysis of image ciphers indicates that permutation-only image ciphers are insecure against ciphertext-only attacks and/or known/chosen- plaintext attacks. However, previous studies have not been able to ensure the correct retrieval of the complete plaintext elements. In this paper, we re-visited the previous works on cryptanalysis of permutation-only image encryption schemes and made the cryptanalysis work on chosen-plaintext attacks complete and more efficient. We proved that in all permutation-only image ciphers, regardless of the cipher structure, the correct permutation mapping is recovered completely by a making multiple combination of two encrypted image. To the best of our knowledge, for the first time, this paper gives a combination attack that completely determines the correct plaintext elements using a deterministic method. Also, the detection of hacker at adminside with the help of IP detection and blocking system is to be done in this system for future prevention of permutation attack.

RER: Reactive Efficient Routing for Wireless Sensor Networks
In Wireless Sensor Networks (WSNs) the major challenge is to provide efficient and reliable communication between source and destination, especially in industrial WSNs (IWSNs) with dynamic and harsh environments. Hence, a Reactive Efficient Routing (RER) is designed to improve the routing protocol to provide efficient packet delivery against the unreliable wireless links. Here Dynamic Source Routing (DSR) protocol is used in the proposed system and a special technique called biased back-off scheme used to find a robust guide path through which cooperative forwarding opportunities are more. So, the data packets are sent to the destination efficiently. Performance of RER is measured using four parameters Bit error rate, Packet delivery ratio, Throughput and Control overhead packet through simulation.
