Abstract: A fault-tolerant distributed decision fusion in the presence of sensor faults via Collaborative Sensor Fault Detection (CSFD) was used traditionally. CSFD scheme is proposed in which the results of a homogeneity test are used to identify the faulty nodes within the network such that their quantized messages can be filtered out when estimating the parameter of interest. The scheme can identify the faulty nodes efficiently and improve the performance of the decision fusion significantly. It achieves very good performance at the expense of such extensive computations as exponent and multiplication/division in the detecting process. In many real-time WSN applications, the fusion center might be implemented in an ASIC and included in a stand-alone device. Therefore, a simple and efficient decision fusion scheme requiring lower hardware cost and power consumption is extremely desired. In this paper, we propose the Approximated Collaborative Sensor Fault Detection (ACSFD) scheme and its VLSI architecture. Sorting operation are required in ACSFD to find out four biggest faulty node indexes for subsequent usage for this purpose .we have implemented different sorting algorithm to evaluate the efficiency of the sorting network

Abstract: One of the applications of Natural Language Processing is Machine Translation. Machine Translation means that by use of software to translate text or speech from one language to another language. Machine translation refers to the use of computers to automate the task of translating between human languages. Machine Translation with Statistical approach helps to do machine translation for any language pair by the use of Statistical tools. This paper describes machine translation with Statistical approach to produce better translation for English to Tamil translation system. We have collected parallel corpus from children story domain. We aligned the sentences manually. SRILM tool kit is used for language modeling. GIZA++ tool is used to build translation model. Moses decoder is used to produce better translation from English text to Tamil text.

Abstract: This brief presents a novel very large-scale integration (VLSI) architecture for discrete wavelet packet transform (DWPT).By exploiting the in-place nature of the DWPT algorithm, this architecture has an efficient pipeline structure to implement high-throughput processing without any on-chip memory/first-in first out access. A folded architecture for lifting-based wavelet filters is proposed to compute the wavelet butterflies in different groups simultaneously at each decomposition level. According to the comparison results, the proposed VLSI architecture is more efficient than the previous proposed architectures in terms of memory access,hardware regularity and simplicity, and throughput. The foldeda rchitecture not only achieves a significant reduction inhardware cost but also maintains both the hardware utilization and high-throughput processing with comparison to the direct mapped tree-structured architecture.

Abstract: This paper reports on the effect of water emulsified diesel fuel combustion on brake thermal efficiency, brake specific fuel consumption, Oxides of Nitrogen (NOx) and Hydrocarbon emissions in a diesel engine. The experiments were conducted on a single cylinder four stroke cycle diesel engine. Initially test was conducted using pure diesel. Two tests also conducted for diesel fuel with 10 % water and diesel fuel with 20% of water by keeping Polysorbate 20 as solvent. From the test results, it was found that the water emulsification has a potential to improve brake thermal efficiency and brake specific fuel consumption. Emulsions of diesel and water are often promoted as being able to overcome the difficulty of simultaneously reducing emissions of both oxides of nitrogen (NOx) and hydro carbon emissions in a diesel engine.
