Abstract

Clos network, a family of multistage networks, is applied to build scalable commercial multiprocessors with thousands of nodes in macro systems. An MPSoC is a system on- chip a VLSI system that incorporates most or all the components necessary for an application that uses multiple programmable processors as system components. This paper presents the design and simulation of clos network that provides the contention free permutation in multiprocessor system on chip (MPSoC).The proposed clos network employs an ID matching scheme with pipelined circuit switching and dynamic path setup scheme based on Exhausted Profitable backtracking (EPB) under a multistage network topology. Due to the pre-configured circuit-switched data paths, applying a source-synchronous data transfer scheme is feasible. The ID matching scheme offers a contention free routing from unauthorized users. The pipelined circuit switching approach offers a guarantee of permutated data. The circuit-switching approach offers a guarantee of permuted data and its compact overhead enables the benefit of stacking multiple networks. The dynamic path setup scheme enables run time path arrangement for arbitrary traffic permutation.

Abstract

Transportation is regarded as an index of economic, social and commercial progress of a country. An adequate and safe transportation is indispensible for economic and social progress of a nation and the world as a whole. Bridges are key components of a transportation infrastructure and restoring their health is an important criteria. This paper deals with a proposal for rehabilitation measures for an existing railway bridge in a southern city in India. The existing bridge faces many problems like smaller headroom, corroded steel plates and needs immediate rehabilitation. Hence an attempt has been made in this work to redesign the existing riveted type plate girder as a welded type plate girder with increased headroom by providing gradients at both the sides of the bridge. A Subway bridge for carriage way under the railway bridge has been introduced to provide a gradual gradient for the carriageway and the drainage system has been designed accordingly.

Abstract

With the explosive growth of multimedia applications, the demand for high performance and low power digital signal processing is getting higher and higher. Finite impulse response (FIR) filters are one of the most widely used fundamental devices performed in DSP systems. This Paper presents a survey on designing Low Area and Low Power Parallel FIR Filter. By using Fast FIR filtering algorithms (FFA), this parallel FIR structures can Lead to significant hardware savings from the existing FFA Parallel FIR filter. In this paper, Traditional FIR filter structure and FFA based FIR filter structure, Symmetric convolution based FFA FIR filter structure are designed for 2-parallel (2×2) and 3-parallel (3×3).

Keywords

Abstract

A Clone Detection approach is to find out the reused fragment of code in any application to maintain. Various types of clones are being identified by clone detection techniques. Since clone detection was evolved, it provides better results and reduces the complexity. A different clone detection tool makes the detection process easier and efficiently produces the results. In many existing system, it mainly focuses on line by line detection or token based detection to find out the clone in the system. So it makes the system to take long time to process the entire system. This paper proposes combination of textual and metric analysis of a source code for the detection of all types of clone in a given set of fragment of java source code. Various semantics had been formulated and their values were used during the detection process. This metrics with textual analysis provides less complexity in finding the clones and gives accurate results.

Keywords

Clone Detection, Metrics, Complexity, Semantics.

Abstract

The speeds of sound and densities were measured for the binary liquid mixture of ethylene glycol with n-butylamine (NBA), sec-butylamihe (SBA), tertbutylamine(TBA), n-hexylamine (NHA), n-octylamine (NOA) and cyclohexylamine (CHA) over the whole mole fraction range at 308.15 K. From the experimental data various acoustical parameters, such as isentropic compressibility (k_s), intermolecular free-length (L_f), relative association (R_A), acoustic impendence (z), excess isentropic compressibility (K_s^E), excess inter molecular free-length (L_f^E), excess ultrasonic velocity (U^E) and excess acoustic impedance (Z^E) have been calculated. The behavior, of the present binary liquid mixtures is discussed in terms of possible molecular interactions between unlike molecules. The molecular interactions are discussed from the increasing number of methylene groups in amines, branching and cyclic nature of the amines which indicates the presence of AB type of interactions exist in these binary liquid mixtures.
