Each learner has different learning status and therefore should use different test items in their evaluation. The Computerized Adaptive Test (CAT) can adjust the degree of difficulty of test items dynamically depending on their ability. One of the most important and challenging issues in conducting a good test is the construction of test sheets that can meet various criteria. Therefore, several measures have been proposed here to represent the quality of each test item. In E-Learning, there is a critical need of formative assessment and hence series of test sheets to be composed which pose some challenges. Consequently the selection of appropriate test items is important when constructing an assessment sheet that meets multi-criteria assessment requirements, such as expected difficulty degree, expected discrimination degree, specified distribution of relevant concept weights and exposure frequency of items. All behavior like selection of items, evaluation and termination of test are based on Item Response Theory, an educational theory. An adaptive assessment system is proposed to compose serial test sheets. This approach will improve the efficiency of composing near optimal serial test items to meet multiple assessment criteria.","PeriodicalId":123210,"journal":{"name":"2013 International Conference on Pattern Recognition, Informatics and Mobile Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117248934","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}

A novel approach for speech feature extraction is by applying the Mel-frequency cepstral co-efficient (MFCC) algorithm using Cubic-Log compression instead of Logarithmic compression in MFCC. In proposed MFCC, the frequency axis is initially warped to the mel-scale which is roughly below 2 kHz and logarithmic above this point. Triangular filter are equally spaced in the mel-scale are applied on the warped spectrum. The result of the filters are compressed using Cubic-Log function and cepstral co-efficient are computed by applying DCT to obtain minimum MFCC feature vector for spoken words. These feature vectors are given as input to classification and Recognition phase. The system is trained and tested by generating MFCC feature vector for 600 isolated words, 256 connected words and 150 sentences in clear and noisy environment. Experiment results shows that with minimum MFCC feature vector is enough for speech recognition system to achieve high recognition rate and its performance is measured based on Mean Square Error (MSE) rate.","PeriodicalId":123210,"journal":{"name":"2013 International Conference on Pattern Recognition, Informatics and Mobile Engineering","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133238584","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}

It does not require any fixed infrastructure due to no wired backbone. It is suitable to use in environment that have need of on the fly set-up. Every host is a router and packet forwarder. Each node may be mobile, and topology changes frequently and unpredictably due to the arbitrary mobility of mobile nodes. This aspect leads to frequent path failure and route rebuilding. Routing protocol development depends on mobility management, efficient bandwidth and power usage which are critical in ad hoc networks. Cross layer scheme is the new method for wireless mobile devices become to increase the capacity network. In this paper, proposed a new cross layer scheme based algorithm to reduce the link break in MANETs. This present three schemes to reduce packet retransmission ratio by distribution signal information between PHYSICAL LAYER and MAC LAYER, and to discuss the frequent route failures in MANET by identify shortly to be broken links instead of prediction of received signal power, To find optimized route maintenance by taking into consideration of Bandwidth, Delay which results by improvement of QoS. The performance of cross layer process for all the schemes simulation are carried out to evaluate network performance using network simulator NS-2 based on the basic parameters like Throughput, packet delivery ratio(PDR) in term of number of nodes when various pause times.","PeriodicalId":123210,"journal":{"name":"2013 International Conference on Pattern Recognition, Informatics and Mobile Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225618","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}
