This paper takes advantage of the macroblock (MB) level parallelism in H.264/AVC encoder and based upon this represents a scheme to implement the encoder for multi-core platform. According to this technique an encoding process of an MB is divided into several independent phases and each phase is executed on a separate processing core. Moreover to efficiently utilize the multi-core processors and to improve the encoder performance, the encoder is pipelined at MB level. The experimental results show that encoding rate of pipelined encoder as compare to sequential encoder is improved from 6 fps to 72 fps and from 2 fps to 32 fps for FD1 (720 × 480) and HD 720p (1280 × 720) resolutions, respectively. The implemented encoder can be used for multimedia applications like video conferencing, smart phones, high quality mobile digital video recorders, tablet computers, mobile digital TVs etc.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131592402","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}

While it provides many advanced features, there are still some shortcomings, such as the exorbitant operational cost. It is indeed at the center of several fields of research. One of them is the energy, under its different forms. The management of energy consumption in the world of Cloud is the one on which we concentrated through this paper, that is part of a work around the energetic aspect of Cloud Computing. The field of Green Computing is becoming more and more important in a world of limited energy resources and a growing demand for greater computing power, it therefore represents one of the major concerns, that we are dealing with in this paper, in order to optimize the consumption of electrical energy in a virtualized Cloud Platform, while respecting the requirements of SLAs. We propose a framework which offers effective improvements in a scalable Cloud architecture. A solution is to dynamically consolidate the Virtual Machines (VMs in the paper) of the platform in a lower number of nodes (hosts), during the time of low load situations, in order to shutdown unsolicited nodes, in the condition of providing an acceptable level of availability and response time and storage capacity so as not to penalize the user and respect the constraints of the service contracts.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122964209","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}

CAPT allows continuous feedback to the learner without requiring the sole attention of the teacher; it facilitates self study and encourages interactive use of the language in preference to rote learning. One of the important processes in CAPT system is error detection, which locates the errors in the utterance. Although Arabic is currently one of the most widely spoken languages in the world, there has been relatively little research about detection of the pronunciation error by nonnative speakers compared to the other languages. This research is concerned with detecting pronunciation errors of nonnative Arabic speakers from Pakistan and India. All the sounds in this study were taken from King Saud University (KSU) Arabic Speech Database. By analyzing the speech of the Pakistani and Indian speakers in KSU database we found that five phonemes were often mispronounced by nonnative speakers, hence this research will concentrate on pronunciation errors in these five phonemes. The system was built with native and nonnative speakers, and tested with nonnative only. For each phoneme, the Goodness of Pronunciation (GOP) was calculated and compared with a threshold to decide if the phoneme was pronounced correctly or not. The result showed that GOP gave high accuracy, where the scoring accuracy was very good to excellent from 87% to 100%, and the false rejection was zero to less than 10%. This machine judgment is compared with human judgment and the comparison shows excellent agreement between them.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126276729","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 accuracy of the evaluation rely on the enhanced mobility and radio link models, which are based on real-time motion capture mobility traces. Bio-mechanical modeling is used to capture 'walking', 'stand-sit' and 'running' patterns for comprehensive mobility modeling. There are multiple contributions in this paper. First, dynamic (i.e., space and time-varying) mobility models are presented which provides dynamic distances and hence more accurate pathloss models in comparison to IEEE 802.15.6 channel models. Second, accurate radio-link modeling is presented which computes on-line Signal-to-Noise-Ratio (SNR), Bit-Error- Rate (BER) and Packet-Error-Rate (PER). Third, a comprehensive analysis of the IEEE 802.15.6 PHY and MAC layers parameters are explored. The rescue and critical applications based specific constraints are used to analyze the IEEE 802.15.6 standard. Finally, few configurations among huge set of possibilities are selected for performance evaluation. Three metrics i.e., Packet Delivery Radio (PDR), energy consumption and latency are considered. At higher transmission power (i.e., 0 dBm), most of the medical applications data rates constraints are satisfied, whereas, at lower transmit power with high data rates and higher frequency, the results does not meet the non-medical applications requirements. However, further optimization by dynamically adjusting the number of slots and its duration at the MAC layer can improve the throughput which can help significantly to meet the application requirements.","PeriodicalId":412749,"journal":{"name":"2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125897715","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}
