There have been multiple works in the past to align sentences in bilingual corpus in English and European languages and some Asian languages like Chinese and Japanese. This work introduces a novel approach for sentence alignment in bilingual corpora using lexical and statistical information about the language pair using genetic algorithm. The only lexical information used in this work is a restricted form of bilingual dictionary (incomplete). The algorithm works based on the weighted sum of a set of statistical parameters and the parameter denoting degree of dictionary match. No other lexical information like part of speech tagging, chunking, n-gram statistics etc has been used in this work. Our approach has been tested for structurally dissimilar language pair of English-Hindi and is shown to yield a high performance even under noisy conditions. We compare our results with that of Microsoft alignment tool on the same corpus and we find our results to be superior","PeriodicalId":308247,"journal":{"name":"2007 International Conference on Computing: Theory and Applications (ICCTA'07)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121093954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our primary goal of this paper is to classify the blurred images rather than measuring degree of blurness in the image or deblur an image. Thus the name given to this approach is Boolean blur metric (BBM). The proposed approach explores new rules based on establishing the unique relationship between the arithmetic mean filter, geometric mean filter and median filter of given image with the help of canny edge detector. The metric uses the disadvantage of arithmetic mean filter and advantage of geometric mean filter and median filers to define Boolean rule. Further, we have shown that the number of canny edge components in filtered images makes difference in defining rule. Finally, the proposed approach is compared with the well known existing no reference perceptual blur metrics to show that existing metrics are not suitable for classification.

This technique can be used for denoising the images extremely corrupted with impulse noise. This paper introduces a spike detection technique (SDT) and pixel restoring median filter (PRMF) for denoising the corrupted images. The SDT is used for discriminating between corrupted and uncorrupted image pixels. The corrupted pixels are restored using PRMF technique. Our iterative denoising technique is repeated until the corrupted pixels in the recovered image reduce to zero. The performance of our denoising scheme is evaluated with salt and pepper noise and also with random impulse noise for different standard images. It is observed that the proposed denoising scheme outperforms all existing impulse-denoising schemes. This technique can also be used for color image impulse noise removal. This technique can remove very high noise up to 98% and the images denoised with our method shows improvement in terms of visual quality, PSNR value and mutual information. This scheme prevents image blurring and is computationally simple.

In wide area distributed systems these algorithms may suffer from large overhead due to message passing delay and network traffic. Mobile agents offer an attractive option for designing checkpointing schemes for wide area distributed systems. Network topology is assumed to be arbitrary. Processes are mobile agent enabled. When a process wants to take a checkpoint, it just creates one mobile agent. Concurrent initiations by multiple processes are allowed. Synchronization and creation of a consistent global state (CGS) for checkpointing is managed by the mobile agent(s). In the worst case, for k concurrent initiations among n processes, checkpointing algorithm requires a total of O(kn) hops by all the mobile agents.

It is heterogeneity and dynamics of the grid that make QoS problems in grid environment challenging. Computational grid's resource management must deal with various demands from users. Each of grid task agent's diverse requirements is modeled as a quality of service (QoS) dimension, associated with each QoS dimension is a utility function that defines the benefit that is perceived by a user with respect to QoS choices in that dimension. The objective of multiple QoS based grid resource scheduling is to maximize the global utility of the scheduling system.

The proposed methodology is demonstrated with a multiplier circuit built using the NAND gate library, by characterizing its dynamic power through Monte Carlo analysis. The statistical technique of response surface methodology (RSM) using design of experiments (DOE) and least squares method (LSM), are employed to generate a \"hybrid model\" for gate power to account for simultaneous variations in multiple process parameters.
