Design & Implement an IP Core for Fast Addition using Quaternary Signed Digit Number System
-Raja Lavudi ; R.Anil kumar; J.Suresh; R.Gopi Reddy
With the binary number system, the computation speed is limited by formation and propagation of carry especially as the number of bits increases. Using a quaternary Signed Digit number system one may perform carry free addition, borrow free subtraction and multiplication. However the QSD number system requires a different set of prime modulo based logic elements for each arithmetic operation. A carry free arithmetic operation can be achieved using a higher radix number system such as Quaternary Signed Digit (QSD). In QSD, each digit can be represented by a number from -3 to 3. Carry free addition and other operations on a large number of digits such as 64, 128, or more can be implemented with constant delay and less complexity. Design is simulated & synthesized using Modelsim6.0, Microwind and Leonardo Spectrum. Read More...

LATERAL LOAD ANALYSIS OF SOFT STORY BUILDING AND IMPORTANCE OF MODELING MASONRY INFILL WITH NORMALIZED STRENGTH AND STIFFNESS RATIO
-Kalappa M sutar ; kalappa m sutar; Prof. Vishwanath. B. Patil
Generally Masonry infills are considered as non-structural elements and their stiffness contributions are generally ignored in practice. But they affect both the structural and non-structural performance of the RC buildings during earthquakes. RC frame building with open first storey is known as soft storey, which performs poorly during strong earthquake shaking. A similar soft storey effect can occur if first and second story used as service story. Hence a combination of two structural system components i.e. Rigid frames and RC shear walls leads to a highly efficient system in which shear wall resist the majority of the lateral loads and the frame supports majority of the gravity loads. To study the effect of masonry infill with different soft storey level, 7 models of Reinforced Concrete framed building were analyzed with two types of shear wall when subjected to earthquake loading. The results of bare frame and other building models have been compared, it is observed that model with swastika and L shape shear wall are showing efficient performance and hence reducing the effect of soft storey in model 3, model 4 and model 5.

-Jasleen Kaur ; Dr. Rajesh Gargi
Rural areas where resource of communication lacks and the area like earthquake zone require a strong communication channel. India is one of the fastest growing countries in the world but fact is there are more than 600 villages still lack the proper communications. Mobile ad-hoc network is one of the networks which often requires seamless ubiquitous network, which can be utilized to structure the wireless mode of communication, for the transmission of strategic information among mobile agents in areas where no rigid infrastructure can be set up for a network. Mobile ad-hoc network is best suited for this kind of situation because of the flexibility and scalability it offers. No central administration is required for such network, as it works on temporary connection links, making the network ubiquitous. The prime challenge in implementing such network with multi-agent communication is the need of an efficient routing protocol for multi-hop connectivity, frequently changing topology and dynamic routes. This paper proposes a new multi-agent based routing algorithm to facilitate the reliable communication in rural areas network. The proposed algorithm is named as Ant Algorithm for Mobile Ad-hoc Network. The proposed algorithm is inspired from the ant colony optimization metaheuristic and is based on swarm intelligence, uses simple node-level management with probabilistic multi-path routing which highly resembles to the behavior of real world harvester ants to find the shortest path between their nest and the food source. This paper will discuss about the security ethics of the Adhoc network. Techniques that will make MANET more secure and Algorithms for security in MANET. Read More...

Optimization of Process Parameters of Tungsten Inert Gas Welding by Taguchi Methodology
-Ashish Singh Solanki ; Ritesh Anand; S C Jayswal
Tungsten Inert Gas welding (TIG) is one of the most important joining technologies in welding-related fabrication. High quality weld joints without spattering and slags qualify this welding technology for the major part of metals. As the filler-metal supply is separated from the arc, the molten pool can be controlled in the best way possible an advantage which ensures the quality of the execution of the weld but entails a relatively low deposition rate and welding speed. When manufacturing consumer products where appearance is of importance; then the choice has to be TIG welding. Jobs that call for code requirements such as nuclear work, piping, and high profile consumer goods often require at least the first weld in the pipe joint to be TIG welding for an effective bond. In some cases all the passes on a multi-pass pipe weld may have to be TIG welding, if demand has high quality and code requirements. Read More...

Modified LAEEBA Routing in WBAN
-Sheth Mahammed Ovesh I. ; Assoc. Prof. Ajay Kumar Sharma
This paper modifies the LAEEBA protocol to enhance the performance of the protocol. Eight sensor nodes are deployed on a human body; having equal power and computation capabilities. Sink node is placed at waist. Different nodes are used to measure various activities like Glucose level etc. In the LAEEBA protocol all the nodes are active at every time, but the total usage period of few nodes is very less depending upon the disease covered. This leads to the wastage of the energy. This work uses the Sleep state to save the energy. The sink node will remain active all the times and the other node are in the sleep state. The node which gets selected for the transmission will change its state to the active state; other nodes will remain in the sleep state. The simulation results show that the proposed technique is better than the existing technique. The comparison is done by using the PDR, E2E Delay and throughput. The delay gets decreased and the throughput gets increased. The PDR in the proposed algorithm is greater than the existing algorithm so the proposed algorithm is better than the existing algorithm.

Design of High Speed and Low Power Veterbi Decoder for Trellis Coded Modulation Decoders
-B.GOVIND ; SK.SUBHAN; D.VENKATRAMI REDDY
It is well known that the Viterbi decoder (VD) is the dominant module determining the overall power consumption of TCM decoders. High-speed, low-power design of Viterbi decoders for trellis coded modulation (TCM) systems is presented in this paper. We propose a pre-computation architecture incorporated with -algorithm for VD, which can effectively reduce the power consumption without degrading the decoding speed much. A general solution to derive the optimal pre-computation steps is also given in the paper. Implementation result of a VD for a rate-3/4 convolutional code used in a TCM system shows that compared with the full trellis VD, the precomputation architecture reduces the power consumption by as much as 70% without performance loss, while the degradation in clock speed is negligible.

FIR FILTER DESIGN USING MCMA TECHNIQUE
-Yallagalla Balaji ; P. Brundavani
Low-cost finite impulse response (FIR) designs are presented using the concept of faithfully rounded truncated multipliers. Here the optimization of bit width and hardware resources without sacrificing the frequency response and output signal precision are considered. In this multiple constant multiplication/accumulation (MCMA) is used to reduce the area, which reduces the cost and power dissipation and hardware resources also reduced. The MCMA module is realized by accumulating all the partial products (PPs) where unnecessary PP bits (PPBs) are removed without affecting the final precision of the outputs. The bit widths of all the filter coefficients are minimized using non uniform quantization with unequal word lengths in order to reduce the hardware cost while still satisfying the specification of the frequency response.

-Bhagyashri Bhosale ; Shubhangi Bandal; Abhiruchi Bhosale; Priyanka Kale
Rich-sensor Smartphones have made possible the recent birth of the mobile sensing research area as part of ubiquitous sensing which integrates other areas such as wireless sensor networks and web sensing. The object of sensing can be people-centered or environment-centered. The sensing domain can be home, urban, vehicular etc. Now there are barriers that limit the social acceptance of mobile sensing systems. Several technical barriers are phone energy savings and the variety of sensors and software for their management. In this article, we design and implement Sherlock technology, which captures a micro-environment through sensors and automatically records sensor hints and optimize the micro-environment of smartphones. We refer to such immediate surroundings as micro-environment, usually several to a dozen of centimeters, around a phone. The platform runs as a daemon process on a smartphone and provides finer-grained environment information to upper layer applications via programming interfaces. Sherlock is a unified framework covering the major cases of phone usage, placement, attitude, and interaction in practical uses with complicated user habits. The main objective is to save battery in mobile sensing systems and provides security. Read More...

Analysis of FinFET based Low Power SRAM Cell
-Sudeep Bhattacharya ; Devesh Tiwari; Mr. A.G. Rao
As CMOS electronic devices are continuously shrinking to nanometer regime, leads to increasing the consequences of short channel effects and variability due to the process parameters which lead to cause the reliability of the circuit as well as performance. To solve these issues of CMOS, FINFET is one of the promising and better technologies without sacrificing reliability and performance for its applications and the circuit design. Among the various embedded memory technologies, SRAM provides the highest performance along with low standby power consumption. In CMOS circuits, high leakage current in deep-submicron regimes is becoming a significant contributor to power dissipation due to reduction in threshold voltage, channel length, and gate oxide thickness. FinFET based SRAM design can be used as an alternative solution to the bulk devices. FinFET is suitable for Nano scale memory circuits design due to its reduced Short Channel Effects (SCE) and leakage current. As the impact of process variations become increasingly significant in ultra deep submicron technologies, FinFETs are becoming increasingly popular a contender for replacement of bulk FETs due to favorable device characteristics. The paper focuses on study of various design aspects of FinFET based SRAM. Read More...
