The approach could get high match of segmentation but also gives a lot of false segmentation points. This work introduced a property based on the usage of Zero Crossing Rate (ZCR) in enhancing segmentation by divergence algorithm. The work starts via optimizing divergence algorithm segmentation performance via parameters tuning. Then the proposed property based on ZCR is applied to divergence algorithm to reduce insertion points. The results of tuning divergence parameters achieved match rate of 99.4% at time tolerance of 0.09 seconds with 69% insertion rate occurrences in comparisons to reference points. The result in applying the introduced ZCR property to divergence algorithm shows that tuning of some ZCR property parameters could reduce insertion between 4% to 45%. However, it would also reduce the match rate. Nevertheless, the method could reduced insertion rate by 5.5% while maintaining match rate of 99.4%.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116348534","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}

The primary objective of the CR is to handle the non-interference rules with any primary users (PUs). Highly sensitive and optimal spectrum sensing detectors are required in order to avoid harmful interference to PUs. Multitaper spectrum seems to be the most appealing one for spectrum sensing CR because of its accurate identification and estimation and low computational complexity. Mulitaper uses small set of tapers and multiple orthogonal prototype filters to reduce the variance. The Fourier transform of a Slepian sequence, originally known as discrete prolate spheroidal sequences (DPSS), gives maximum energy density inside a given bandwidth and less spectral leakage with better specifications has been investigated in this paper and shows that no other window in signal processing can satisfy this property.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128716966","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}

In order to avoid these difficulties this project presents new construction of character recognition tool using the technique similar to that is used in image compression such as wavelet compression or JPEG compression. Wavelet compression is chosen as the technique implemented for this project. Wavelet compression technique extracted the important coefficient from the images. The Euclidean distance between the coefficient of the test images and training images is computed. Character is considered recognized if the Euclidean distance calculated is smaller than the Global threshold value of 258.

The objective of this paper is to evaluate the performance of AODVH using ns-2 simulations with varying network size and compare with three other Ad hoc routing protocols. We also implemented and tested AODVH in the laboratory using a testbed consisting of Linux based Ad hoc nodes.

Cancer cells, very often, grows resistance to a drug if it is administered alone for a long time and drug resistance eventually causes failure to treatment in most cases. The adaptation of multi-drug treatment in cancer increases the drug performance by reducing the drug resistance. But care must be taken to design the multi-drug scheduling so as to equilibrium the drug beneficial and adverse side effects of the treatment. Conventional clinical methods can hardly find optimum dosages of drugs that can kill maximum cancerous cells with minimum toxic side effects. This is because of the inherent conflict between the cell killing and the toxic side effects in case of cancer. This paper presents a novel method of multi-drug scheduling using multi-objective genetic algorithm (MOGA) that can trading-off between the cell killing and toxic side effects during the whole period of treatment. A close-loop control method, namely Integral-Proportional-Derivative (I-PD) is designed to control dosages of drugs to be infused to the patient's body and MOGA is used to find suitable/acceptable parameters of the controller. A cell compartments model is developed and used to describe the effects of the drugs on different type of cells, plasma drug concentration and toxic side effects. Results show that drug scheduling obtained through the proposed method can reduce the tumour size more than 99% with relatively lower toxic side effects. Moreover, the drug dosage and drug concentration remain at low level throughout the whole period.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127652371","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}

Women suffer from severe discrimination, due partly to a lack of access to information. Information and communication and technologies (ICT) are tools that potentially can reach rural women and address their knowledge and information needs. Considering this scenario, the aim of this paper is to examine the situation of rural women using ICT tools provided by non-government and government organizations, and investigate whether access to ICT has changed their lives in terms of socio-economic development. Using a structured questionnaire, data was collected from women in villages where two different ICT projects have been introduced. The change in women's awareness, skills and knowledge of the wider environment on various issues (including health, education, legal rights) is described. These cognitive changes were compared in women with ICT intervention and women who did not use ICT. The overall cognitive awareness of the women indicates more changes among women with ICT intervention than without. Therefore, ICT intervention in rural villages in Bangladesh is leading to empowerment.","PeriodicalId":149135,"journal":{"name":"2010 13th International Conference on Computer and Information Technology (ICCIT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116350433","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}

The proposed approach decomposes the test problem in such a way that leads to more effective knowledge acquisition and improved control performance in fuzzy control. In this self-learning adaptive method, Truck backer-upper problem, an excellent test-bed for fuzzy control systems is considered as test problem. Each rule base is represented by a real-coded triploid chromosome. At each generation of QEA, rules are updated using Complementary Double Mutation Operator (CDMO) and Discrete Crossover (DC).
