The focus of this paper is on kernel loops (K-loops), which are loop nests that contain hardware mapped kernels in the loop body. In this paper, we propose methods for improving the performance of such K-loops, by utilizing standard loop transformations for exposing and exploiting the coarse grain loop level parallelism. The goal is to achieve a reconfigurable architecture that is a heterogeneous system consisting of a general purpose processor and a field programmable gate array (FPGA). In this work, different architectures are developed to give solutions to different problems: how to partition the application - decide which parts to be accelerated on the FPGA, how to optimize these parts (the kernels), what is the performance gain. So far, few researchers have exploited the coarse grain loop level parallelism.

Single Carrier Frequency division multiple access is a technique which uses a single carrier modulation at the transmitter and frequency domain equalization at the receiver. It provides same performance and same overall structure as those of an OFDMA which has high peak to average power ratio. The advantage of SC-FDMA is its lower PAPR due to its single carrier structure. In this paper, a Super frame using interleaved mapping (SF-IFDMA) is proposed which provides low PAPR. In this paper we simulate and analyze the PAPR for SC-FDMA using super frame mapping. Simulation result shows that the PAPR in the proposed scheme is 3.24 dB.

The authors have demonstrated SOA-based all-optical XOR at 100 Gbps through simulation. The performance of the proposed all-optical XOR is also analyzed. The proposed design is simpler in structure and provides the user with an option to give two different data input signals simultaneously, eliminating the need of optical delay lines. Also, it allows scope for photonic integration which is imperative to realize higher level components like half-adder, full-adder etc. In comparison to fiber based gates, SOA based gates offer wide bandwidth and are simpler in structure. Most of the published designs of all -optical gates work up to 10 Gbps. However, the proposed design of XOR gate can be operated up to 100 Gbps.

This paper considers a nxm no-wait flowshop scheduling problem in which each job has an uncertain processing time on the machines. The objective of this paper pertains to determine an optimal or near optimal sequence for n-job problem which associates ‘weight’ with each job in the sense of relative importance in the process and includes job block and transportation time of jobs from one machine to other to minimize the total weighted mean flow time.

Additive White Gaussian Noise (AWGN) and Timing Jitters are one of the most significant impairments in long distance fiber optical communication. In optical system communication system high data rates leads to some limitation like dispersion, noise, non-linearity and various jitters for example deterministic and random jitter. This paper reveals some of the drawbacks of the conventional techniques used for noise and jitter compensation. This paper brings out various pulse shaping filters which can be used to compensate noise and various timing jitters in optical communication. This paper also compares the performance of three pulse shaping filters on the basis of output Signal to Noise Ratio (SNR).

Software Architecture modeling and representation is very important in software development process. Software Architecture provides high level view which is very useful in all phases of software life cycle. Component based software architecture is beneficial as it is useful for reusing system parts represented as components. Most of the existing object oriented systems do not have reliable software architecture and some legacy systems are designed without software architecture design phase. To deal with this problem we have proposed approach of architecture recovery which aims to extract component based architecture from existing object oriented system using existing dependencies among classes. In this paper we examine existing object oriented system to identify dependency among the classes using method coupling, inheritance coupling and composition coupling. The tool has been developed for this purpose. We evaluated the feasibility on Java software.

Wireless networks in small or large coverage are increasingly popular as they promise the expected convergence of voice and data services while providing mobility to users. Combining with current wireless communications infrastructure, wireless computing infrastructure and mobile middleware, mobile commerce provides consumers with faster and personalized services and is becoming one of the most important wireless applications. Unless the transmission, storing and processing of information is secure, neither customers nor service providers will trust mobile commerce systems. From a technical point of view, mobile commerce over wireless networks is inherently insecure compared to electronic commerce over wired networks. A number of machine learning algorithms has to be redesigned to address growing concerns with security due to unlimited explosion of new information through internet cloud and other media. In this paper, we have presented the applications of association rules, privacy decision-tree model, Artificial Neural Network, Support Vector Machine, and HMM. Mobile security is a crucial issue for mobile commerce.
