Design and Analysis of CMOS Based DADDA Multiplier
P. Samundiswary, K. Anitha
Abstract
Multiplier is an important circuit used in electronic industry especially in digital signal processing operations such as filtering, convolution and analysis of frequency. There are different types of algorithms used in multipliers to achieve better performance. Array multiplier and Wallace tree multiplier are such types of multipliers constructed by using CMOS logic styles such as Swing Restored complementary Pass-transistor Logic (SR-CPL) and Dual Pass-Transistor (DPL). SR-CPL is constructed by using n-MOS transistor that is derived from Complementary Pass Logic (CPL) logic which is traditionally applied to the arithmetic building block and it offers high speed. DPL is constructed by using both n-MOS and p-MOS which has more number of transistors compared to that of SR-CPL. But high robustness is achieved through DPL. However Wallace multiplier offers higher power consumption. Hence, DADDA multiplier is designed by using ripple carry and carry save adder method with the above mentioned two logic styles. The simulation is done by using TANNER EDA tool.

Multilevel Framework of ICT for Improvement in Public Distribution System for Developing Countries
Sachin Kumar, Shobha and Saibal K Pal
Abstract
Some developing countries are facing severe problems now days which are hindering their speed of development and future prospects. There is unrest in citizens for public institutions due to corruption, less accountability and non transparency in government process. One of the burning problems which add more to existing problems is conventional Inefficient Public Distribution System which further makes public policy implementation inefficient due to absence of ineffective and inefficient or no feedback mechanism. Conventional PDS mechanism is viewed as linear transmission systems of benefits delivery. This PDS is top-down process and hence struggles with quickly adapting to market dynamics and globalization. In this paper prospect for social innovation with ICT emerges at the dynamic intersection of informal, conventional PDS, top down approach of services and goods delivery of the systems in the developing world. With the demographic changes developing countries are experiencing more demand of government benefits in social or infrastructural sector so it is time to utilize the ICT tools and mechanisms to improve conventional PDS systems which is free from the severe loopholes of leakage, unaccountability, non transparency and no feedback mechanism from bottom to top in timely manner. New solutions needs to utilize potential of ICT in three aspects: to increase ease of access and relevance of material through its integration into the PDS, To remove or reduce leakage and to introduce a feedback mechanism loop that enables players at all levels of the PDS and System itself to actively contribute to solutions of problems evolving constantly with dynamic changes. In this paper we are proposing Multilevel ICT enabled public distribution system model which can be implemented with the already existing PDS to remove ready existing problems in conventional PDS. Two models on platform of ICT are proposed for developing countries having ICT enabled identification system of citizens and the countries not having unique identification platform based on ICT. With the help of models, Paper is providing very effective and efficient way of benefit transfer and feedback mechanism. This can be easily implemented in developing countries if country is having exposure in ICT like India, Brazil, South Africa, Mexico and others.

Texture Analysis of Thyroid Ultrasound Images for Diagnosis of Benign and Malignant Nodule using Scaled Conjugate Gradient Backpropagation Training Neural Network
Shrikant D. Kale, Krushil M. Punwatkar
Abstract
A thyroid is largest endocrine gland, a butterfly shape with two lobes which produces hormones that control body metabolism. The nodules are found in thyroid may be benign or malignant. The ultrasound (US) preferred over the other medical imaging modalities which is used to observe the subcutaneous body structures & internal organs for possible pathology or lesions. The physicians are deducing useful information concerning the tissue characterization and structure which is still subjective matter, Thus quantitative analysis of US images give the objective method for thyroid nodule diagnosis. In this paper, gray level co-occurrence matrix (GLCM) texture characterization techniques are used for feature extraction & extracted features are classified using scaled conjugate gradient backpropagation training neural network (SCGBNN) for diagnosis of thyroid nodule are described. The experimental results show the performance measure of SCG backpropagation training neural network in terms classification accuracy.

Studies on Growth and Performance of Indian Commercial Banks during Global Economic Recession
D. Sudha Rani, P. Vijay Kumar and K. Rama Mohana Rao
Abstract
The economic development of a nation is closely related to the efficient performance of the commercial banks. India witnesses the operation of various types of commercial banks with different conditions of managements and common goal of profit making. During the period 2009 to 2012 the world economy has encountered a drastic change due to global crisis. The economic situation in developed countries such as U.S.A and U.K, etc, have significant influence on banking performance of developing countries. The differential growth and performance of Indian commercial banks reflect the stability of Indian economy during this period. The purpose of the study is to understand the performance and growth of different categories of Indian commercial banks during the period 2009 to 2012. This period includes during the global economic crisis and after the crisis. Through a comparison of banking parameters’ and their performance measures stability and robustness of various categories of Indian commercial banks is studied. This study found that during the global economic crisis the Indian commercial banks have shown a positive trend for development. It is observed that, during this period the SBI performed much better than the other public sector banks. With respect to the banking performance measures the 7 new private sector banks have shown an increasing trend. The study concludes that the SBI and the 7 new private sector banks have better managerial efficiencies than the other Indian commercial banks.

Transmission of DWT Image over OFDM Fading Channel with Channel State Feedback
Rajesh Maddirala, K. Anusudha
Abstract
In OFDM system the transmission in fading channel is the challenging issue. Due to this fading, subset of carriers may be affected and they are cancelled at the receiver and it is also not possible to retransmit the lost packet. If the channel state information is available at the transmitter it is easy to retransmit the data by mapping and give the description effectively onto the good sub carrier and eliminate the bad sub carries which produces high channel error at the receiver. This paper describes the saving of energy approach for transmission of first level discrete wavelet transformed (DWT) based compressed image over fading channel. With the availability of channel state information at the transmitter and the description based on the descending order priority. This will reduce the consumption of power in the system, by dropping the data onto the bad subcarriers with mapped description at the transmitter. The parameter that were analyzed for system power consumption without effecting the data are in terms of peak signal-noise ratio(PSNR), distortion, Bit error rate(BER) are simulated using MATLAB. It gives 60% of energy saving.

P. Samundiswary, S. Kalpana
Abstract
Digital filter plays an important role in Very Large Scale Integration (VLSI) technology. The existing Finite Impulse Response (FIR) filter has long transient response which is the major limitation. To overcome this drawback, Residue Number System (RNS) based FIR filters is developed which is described in this paper. High-speed is obtained by introducing the residue arithmetic concept that permits the computation of the filter output by using N FIR sub filters of reduced dynamic range operating in parallel form. Three moduli sets are used in RNS based Filter. 4-tap Low Pass Filter (LPF) type of FIR filter and RNS based FIR filter with 4-tap LPF are designed using Verilog language and analyzed in this paper. The simulation is done by using Xilinx tool Integrated Software Environment (ISE)-13.1

Visual Studio - Continuous Integration
Rama Murari, Veerabhadraiah Sandru
Abstract
Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least once a day - leading to multiple integrations. The shift in the development models from waterfall to agile, the distributed environments, parallel development, frequent and rapid feedback, inspections, deployment and repeated automated testing encourages the organizations to adapt continuous integration. Continuous integration is a practice to be followed by the teams in addition to the usage of tools for automating the process. There are different tools for different elements of the continuous integration like build tools, test tools, code coverage tools, deployment tools etc. These tools are provided by different vendors. Organizations’ selection of CI tools becomes tedious as a careful selection of mix and match of the tools has to be done after thorough evaluation. Visual Studio provides a one stop shop for continuous integration implementation by having features to support all these needs of continuous integration. Organizations which have heavily invested in Microsoft technologies or moving towards it can look at Visual Studio for their CI needs. The tight integration of Microsoft technologies, tools and Visual Studio makes a valuable proposition for customers This paper provides the quick overview on the philosophy behind continuous integration and gives details of VS support for CI practice and deep dives into the various features of VS that will support CI implementation.
