In this paper we proposed a multiple queries optimization for data streams processing on cloud computing (MQODS) frameworks that efficiently execute multiple queries simultaneously on the cloud environment based on their commonalities (common sub-queries). Also we proposed the optimized global plan (OGP) algorithm for data streams' multiple queries over the cloud environment. It generates an optimized global plan for executing multiple continuous queries at the same time on cloud environments. The experimental results prove that the proposed solution MQODS improves the overall performance of data stream processing over multiple queries on the cloud environment.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114364636","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 provides high level of abstraction for the designer through the concept of software components (SWC) and virtual function bus (VFB). Unfortunately, no mature simulation tool is available to simulate the system at the VFB level which disables evaluating the model before system integration. On the other hand, SystemC provides a framework to simulate, analyze, and verify software. Besides, it considers the timing behavior of hardware and communication buses. The similarities and analogies between SystemC modeling components and AUTOSAR software component (SWC) modeling encourages us to rely on SystemC to propose a flow to the designer of AUTOSAR system for timing simulation purpose. In this paper, we present a tool that uses SystemC simulation kernel to provide quick simulation for the designer of Automotive based systems.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129522705","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}

First, we use predefined sparse dictionaries to estimate an initial version of the latent image. To estimate the PSF, four stages are performed. First, a set of directional low-pass filters are applied to the input image. These filters greatly reduces the noise while preserving the blur info in the orthogonal direction. Second, an initial kernel estimation is performed for each filtered image using the initial latent image that was produced by sparse representation. Third, discrete radon transform is applied to each estimated kernel on the orthogonal direction to the low-pass filter and the set of projections at different angles are stored. Fourth, an inverse discrete radon transform is applied to the stored projections and the estimated final kernel is produced. Finally, iterative deconvolution approach is performed to estimate the final latent sharp image. Experimental results showed that the best obtained PSNR is 28.654 at 0.054 noise ratio, whereas the best obtained SSIM is 0.9265 at also 0.054 noise ratio.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134285451","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 goal of this paper is to propose a classification framework for diagnosing different focal liver diseases based on ultrasound (US) images. Ultrasound medical imaging is one of the most common modality, which is used in diagnostic systems because of its safety and cost effectiveness. In this paper, we introduced a framework for a CAD system to diagnosing three classes of focal liver diseases, which are Cyst, Hemangioma (HEM), and Hepatocellular Carcinoma (HCC). The proposed system begins with a preprocessing step to make enhancement and noise removal of US images using a median filter. The segmentation of the liver lesions regions is done using level set method followed by the fuzzy c-mean clustering algorithm. Finally, we have used a multi-support vector machine (multi-SVM) classifier to diagnosis the classes of the focal liver diseases. By using 10-fold cross validation method, we have got an overall classification accuracy of 96.5%. Our proposed system is compared with some state of the art techniques. The experimental results show that the proposed system gives better overall accuracy than the other tested techniques.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"233 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116239525","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}

Frequency hopping spread spectrum (FHSS) is an effective mechanism used to mitigate the effects of jamming, fading, and interference. To improve the performance of FHSS many adaptive frequency hopping schemes are used such as matched frequency hopping (MFH), clipped matched frequency hopping (CMFH), and advanced matched frequency hopping (AMFH). These schemes adaptively select the hopping pattern that includes only good sub-channels. Using these schemes result in forcing the system to be vulnerable to smart jammer attack. In this paper we propose a new algorithm that synthesizes one dimensional chaotic map which generates a random code that mostly selects good sub-channels to achieve good bit error rate (BER), good frequency diversity, and secure transmission provided by the high randomness properties of the chaotic systems.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122782314","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 addition, the security measures applied in MANETs (like encryption and key distribution) have a number of negative effects on the network's performance. Cryptographic operations introduce a lot of both CPU and communication overhead. Therefore, routing protocols improvement is a challenge for researchers to overcome the negative effects of security measures. Clustering the MANET is a known technique to lower the routing over-head. It can also be utilized to distribute encryption keys and the authentication process. In this paper, a new protocol called Secure Clustering and Energy Saver Protocol “SCESP” is proposed. SCESP secures the Mobile Ad hoc Networks and increase its network lifetime. This system introduces a novel self-node clustering technique based on Ad-hoc On-demand Distance Vector “AODV” routing protocol. In addition, it eliminates the key distribution overhead using smart token or similar hardware which is used for authentication. The SCESP system succeeded to enhance the security level of MANETs and decrease the battery consumption of mobile nodes due to the transmitted and received route requests messages propagated to discover new routes in AODV routing protocol.","PeriodicalId":227813,"journal":{"name":"2015 Tenth International Conference on Computer Engineering & Systems (ICCES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131753902","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 this paper, we propose a selfishness detect-and-motivate (SDM) approach that detects selfish nodes and motivates them to cooperate in data delivery. We built a MANET simulator and implemented the proposed approach, and compared its performance with a selfishness detect-and-isolate (SDI) approach and a selfishness unaware (SU) approach.
