Noor, Sayid Khorsandroo","doi":"10.1145/2345396.2345470","DOIUrl":"https://doi.org/10.1145/2345396.2345470","url":null,"abstract":"The wide range of multimedia services has been attracting more users every day, while the increasing number of users plays an important role in the competitive advantage for network/service providers. Due to the fact that the users are the ones who pay for services, their satisfaction is an important goal for each provider in order to survive in the highly competitive market of multimedia services. Because of the nature of multimedia services, users can instantly detect any quality disturbances. For example, users might tolerate several interruptions during a download or upload process, but they may get irritated as soon as they experience a small amount of voice or video disturbance while they are watching their favorite movie through the internet for instance. Thus, quality of experience (QoE) should be maintained at a steady and acceptable level to satisfy users. To do so, it is necessary to identify the contributing factors in the network which affect multimedia quality. Generally speaking, delay, jitter, loss, and bandwidth have considerable impact on multimedia service quality. Because quality of service (QoS) is among the greatest impacting factors of QoE, it seems required to define a quantitative relation between QoE and QoS in order to keep the QoE at an acceptable level. This paper aims to benefit from psychophysics laws to devise quantitative relations which explain the interdependency of QoE and QoS. The proposed quantitative relations are expressed as equations which are then compared in theoretical and experimental setting to indicate which one can better reflect the relationship between QoE and QoS. A video streaming service affected by packet loss was also chosen as a candidate for our test bed. The test-bed results are then estimated by non linear regression and then validated by goodness of fit indexes. In this way, it can be examined how strongly each equation can express the dependency between QoE and QoS.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114534225","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 Universal Networking Language or UNL facilitates translation between Natural Languages across the world. The paper focuses on the linguistic aspects of Malayalam required for the deconversion process. The case marking module handles the different UNL relations and their corresponding language features in Malayalam. A Morphological Generator takes care of generation of Malayalam words with the appropriate case endings and features, with respect to the cases and UNL attributes present in the UNL expression. The words are rearranged by the Syntax Planning Module to produce proper Natural Language sentences. These language dependent features for Malayalam have been successfully incorporated into a Deconverter Framework that handles English and Tamil currently. The Deconverter for Malayalam can currently produce simple Malayalam sentences and handle sentences with single clausal phrases also. It is being enhanced to handle more types of sentences. The present system is a small achievement towards attaining a complete translation facility for the Malayalam language. The following sections examine what has been implemented so far in the Deconverter and what more can be done to realize that dream of a translation facility.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125790574","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 the case of real-time data integration the updates occurring on the source systems need to be reflected in the data warehouse immediately. One important element in real-time data integration is the join of a continuous incoming data stream with a disk-based master data. In this context a stream-based algorithm called X-HYBRIDJOIN (Extended Hybrid Join) has been proposed earlier, with a favorable asymptotic runtime behavior. However, the absolute performance was not as good as hoped for. In this paper we present results showing that through properly tuning the algorithm, the resulting Tuned X-HYBRIDJOIN performs significantly better than that of the previous X-HYBRIDJOIN, and better as other applicable join operators found in literature. We present the tuning approach, based on measurement techniques and a revised cost model. To evaluate the algorithm's performance we conduct an experimental study that shows that Tuned X-HYBRIDJOIN exhibits the desired performance characteristics.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121742789","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 parallel processing exhibited by the large number of processor increases the challenges and design issues for the real time process (critical task) execution on the processor cores. This is a vital part from the operating system scheduling and storage compaction point of view. In this paper we combine the AMAS theory of multiagent system with the affinity based processor scheduling and this will be best suited for critical task execution on multicore platforms. This hard-soft processor affinity scheduling algorithm promises in minimizing the average waiting time of the non critical tasks in the centralized queue and avoids the context switching of critical tasks. That is we assign hard affinity for critical tasks and soft affinity for non critical tasks. The algorithm is applicable for the system that consists of both critical and non critical tasks in the ready queue. Since we use the actual round robin scheduling for non critical tasks and due to soft affinity the load balancing is done automatically for non critical tasks. The novel storage compaction (garbage collection) algorithm consists of local and global garbage collectors which efficiently identifies and removes the unwanted files or information in the distributed or multicore environment making a room for efficient scheduling. We actually modified and simulated the linux 2.6.11 kernel process scheduler to incorporate this scheduling concept. Our result shows the maximum cpu utilization for the non critical tasks and high throughput for the critical tasks.","PeriodicalId":290400,"journal":{"name":"International Conference on Advances in Computing, Communications and Informatics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130439624","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}
