The proposed scheduling scheme provides the lowest Packet Loss Ratio (PLR) for RT multimedia services, this can be achieved by taking the expiration time of the head of line packets of users' queues into account. Also, the proposed scheduling algorithm which we call Modified-Earliest Due Date (M-EDD), achieves higher bitrate for the RT applications. Especially for the video traffic, results have remarkably demonstrated that the M-EDD scheduling algorithm has the capacity to clearly outperform the conventional scheduling schemes.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116538393","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 observability of parametric faults is evaluated by determining a proper test signal that maximizes the error between the good and the faulty circuit at a target fault. The efficient method to optimize the multi-frequency test set by determining the basis of the decision matrix is presented. The decision matrix is calculated from the frequency set of the test signal, extracted from the testability analysis. This set is ranked by calculating the total fault coverage of each test signal. The analog test problem is formulated as selecting an optimal subset from an initial test set defined in terms of fault coverage and fault separation on a given fault set.

Feature values (events) of symbolic data are generally not single values, as in the classical case, but rather list of values, intervals or, more generally, distributions. This study proposes a symbolic classification algorithm that uses distinguished variations in the frequency of frequent one and two item-sets extracted from each class sample. The events and events pairs that have enough high support in one class and very low in others are identified. A symbolic profile is built using identified item-sets. Incoming pattern is compared to the profile of each class and the class that achieves maximum similarity with the object to be classified is selected. Experimental study on two standard datasets shows that the proposed algorithm uses a small subset of events pairs in building a profile of each class and is able to achieve a comparable accuracy with less computational complexity compared to variants of the state of the art SVM.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127445186","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 resonant frequency of the antenna can be electronically tuned by changing the effective electrical length of the resonant slot, which is accomplished by employing the varactor diodes inside the slot. Moreover, the simple biasing of the varactor diodes has a small effect on the antenna performance. Simulation results show that the proposed antenna is capable of frequency switching over a tuning range of 0.93 GHz from 1.83 to 2.76 GHz with 40.5 % frequency tuning range.

PS (proportional share) schedulers are the dominant schedulers in Virtual Machine (VM) environment. A PS scheduler assigns a weight to every VM to allocate CPU cycles, allocating these cycles to VM is proportional to that weight. Current VM scheduling algorithms don't aware about the attributes (e.g. weights and number of threads) of the running processes in VMs. We illustrate this issue through experimental evaluations of the current scheduling thus revealing its weakness. A modification of current scheduler is proposed in this work to enable users to specify weights to VMs. Therefore, user gets CPU usage proportion to the assigned weight, the higher weight the more CPU usage and vice versa. In addition, a pricing calculator is considered to calculate the fee that the user should pay according to his desired CPU usage. Derived results show that our modification achieves accurate proportional fairness for a diverse set of workloads.","PeriodicalId":362288,"journal":{"name":"2016 Fourth International Japan-Egypt Conference on Electronics, Communications and Computers (JEC-ECC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134316524","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}

Third, Euclidean distances are calculated between each gray level co-occurrence matrix and a reference one for both defect-free and defected images. Forth, the resultant Euclidean distances are compared to pre-calculated thresholds to identify the defected blocks.
