However, designing a more reliable and effective routing protocol to assure utilizing the emerging advantages for such a paradigm is still a challenging task. In this context, two novel schemes are presented in this paper; the first one is expected to enhance the network performance by reducing route errors and overhead through considering multi-effective-criteria in selecting routes, as well as predicting their lifetimes, in addition, to control the dissemination-width of route requests (RREQs) during route discoveries. While the second scheme extends the first method to further argues the dissemination-depth control of RREQs aiming to reduce the overhead of unnecessarily repeated attempts of route discoveries. Furthermore, intelligent techniques of artificial bee colony (ABC) optimization and fuzzy logic are employed in the proposed schemes. The conducted results through simulation validate the investigated schemes.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116041238","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 damaged signal may be improved using system modulation and de-modulation technique through the advancement of the proposed method. When those variations are considerable over the data frame duration, developing precise channel estimators that are able to track the variations of a channel is especially important for the reduction of the training signalling that is required for adaptation of parameters. The suggested model is designed with the use of VHDL and verified for being functional in Model-Sim and implemented targeting Virtex-5 enhancement kit. The projected frequency of operation of the design is 102.097MHz; the area is 15% of the entire available area and the entire power of 0.314 W, which leads to better results model according to the area, power and speed performance.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122174230","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}

Video compression techniques are developed in many areas such as (educational and medical, …etc.). Contourlet transform (CT) is used in this paper with a motion compensation technique (MC) for video compression purposes. CT has a good ability to retain image details because it avoids downsampling to a high-frequency sub-band, and the coefficients are also very sparse, by exploiting these features CT is used along with MC which overcomes the disadvantage of not synthesizing the current frame from the previous frame accurately such as in simple frame differencing technique. In this paper CT is applied to two frame’s prediction techniques of the video: simple frame differencing (classical method) and motion compensation. The results show the excellence of CT with MC, where the compression efficiency is improved. Results have obtained with these techniques in terms of Peak Signal to Noise Ratio (PSNR), Compression Ratio (CR) and a Bit Per Pixel (BPP).","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128183456","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}

Harmonics can lead to excessive heat and noise in the loads and create a large amount of energy losses either in transmission systems or distribution systems. Compensation of these harmonics substantially improves the power factor and reduces the total harmonic distortion index (THD). This means that the system can transfer more active power without having to increase the capacity. Traditionally, passive filters have been used to remove harmonics, but for their intrinsic downsides, they have been replaced by active power filter (APF). APF has superior filtering characteristics and dynamic response compared to passive filters. Synchronous Reference Frame (SRF) has been widely adopted for harmonics extraction in APF, although it has been found out to have a slow response. Discrete Wavelet Transform (DWT) on the other hand, is a good candidate for harmonics extraction. The new controller is thoroughly developed and rigorously simulated in MATLAB-Simulink environment. The harmonics source is a 5.5 kW nonlinear load mimicking a real-life load from previous practical studies. As a conclusion, DWT is a better candidate for harmonics extraction in APF, as compared with SRF.","PeriodicalId":357053,"journal":{"name":"2018 Third Scientific Conference of Electrical Engineering (SCEE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131898668","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}
