Current E-Learning systems provide content to the students as a whole, needing effort from the students to identify, discriminate and classify contents to be covered for particular topics. In this paper, a Learning Management System (LMS) is presented that provides students with electronic materials and supporting tools to inculcate Self-regulated Learning by the way of providing an environment to learn a programming language. The course contents of language are dynamically provided to the students appropriate to the level of knowledge acquired using Adaptive Learning Objects (ALOB). Students learn the contents to achieve the goal set by the teacher at the start of each level. Students monitor their learning process using a set of tools provided by the system and manage their time, effort and reading being spent in learning the provided content. Students assess their knowledge and take suitable corrective actions when required. The system is implemented as web services and made accessible anywhere, anytime by deploying it over a cloud. The results show that the students who underwent the course show increase in the self-regulation components and the interest to learn in-depth.","PeriodicalId":191151,"journal":{"name":"2012 International Conference on Recent Trends in Information Technology","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115567441","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}

This paper describes a fast algorithm based on Normalized Cross Correlation for real time target tracking in a video sequence. The Normalized Cross Correlation is efficiently implemented in practice with the concept of Box Filtering and Integral Image to eliminate redundant computations. But NCC-BF and NCC-II still have lot of redundancies in exhaustive template matching process. This paper proposes an upper bound criteria called as Early Elimination Condition, which states that the calculated optimum correlation score at current position is lower than the maximum correlation score obtained in previous position. This condition accelerates the matching process. In this paper, it has been proved that if this condition is verified, then the template can proceed with next reference position without executing the rest of operations in current position. Hence, the redundancy in NCC based object tracking can be efficiently reduced by our proposed elimination condition described in this paper. The performance of the upper bound criteria is established by tracking various objects captured from large set of video clips.","PeriodicalId":191151,"journal":{"name":"2012 International Conference on Recent Trends in Information Technology","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124041262","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}

But, if the communication pattern is changed, decisions taken at design time (say buffer size) may result in large area and power consumption or higher latency. Using large buffers to guarantee performance leads to excessive power dissipation. Small buffers reduce power consumption but result in increase in latency. The purpose of the proposed work is to design a heterogeneous router where the buffer slots are dynamically assigned to improve the performance, under different communication needs in fault-tolerant adaptive NoC applications. In the proposed router, buffer slots can dynamically be re-allocated for various applications to improve performance. Reallocation is based on the number of hotspots using EBLA (Extended Buffer Loan Algorithm). By introducing oversized IPs (OIPs), regular mesh-based NoC architecture may be destroyed. Resulting mesh-based NoC becomes irregular and needs new routing algorithms to solve routing problems in case of faulty links. A NoC with irregular 2D mesh topology is considered and an fault tolerant adaptive routing algorithm is used.","PeriodicalId":191151,"journal":{"name":"2012 International Conference on Recent Trends in Information Technology","volume":"84 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130671893","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 consists of an externally worn speech processor and an internal receiver stimulator. The cochlear implant is patient specific and system specific and so in the current work, a lab model for the speech processor, based on various vocoder models is designed to analyse the effect of system specific parameters such as filter bandwidth, number of channels and vocal excitation, on the speech intelligibility. Initially a formant vocoder is designed and used in the analysis and synthesis of English vowels. A channel vocoder is then developed for the same and extended to perform the analysis and synthesis of words from the Lexical Neighbourhood Test and sentences from the TIMIT database. The effect of number of channels on the synthetic speech quality is analysed and a 21-channel vocoder is found to yield the best response with a mean opinion score (MOS) of 4 out of 5 for vowels and 3.4 for sentences. The formant trajectories and CosH distance are also used to validate the speech intelligibility. The influence of glottal pulse on speech intelligibility is analysed and the synthetic speech is found to sound more natural with a glottal pulse train than an impulse train with an MOS of 4.2 for vowels and 4 for sentences.","PeriodicalId":191151,"journal":{"name":"2012 International Conference on Recent Trends in Information Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122809719","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}
