Using our TBS has allowed us to examine patterns of individual navigations through the HLE that reflect quality of self-regulation, the nature of the privileged pathways of learners, resources visited and time spent on each type of cognitive regulatory activity.

The proposed method has been investigated based on different chromatic dispersion levels. The objective of this procedure is to minimize the FWM nonlinear effects in dense WDM optical network regardless of chromatic dispersion phenomenon. As known, the main problem about treating FWM and Chromatic dispersion in optical fibers is that they are inversely proportional. That is why a module able to fulfill these two main limitation simultaneously is of great interest. The WDM transmission system is simulated using the advanced tools of Optisystem 7.0. The simulation results have been examined and validated by analyzing the optical spectrum analyzer and the eye diagram for the eight optical channels.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"20 11-12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116716784","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 low-frequency power line cable attenuation is linearly approximated based on two-conductor Transmission Line (TL) theory and field measurements. The Matrix Pencil (MP) algorithm is used for the model parameters identification and allows, with a quick convergence and a very low residual error, to detect the dominant propagation paths number as well as their corresponding weighting factors and delays.

In order to electronically sweep the resonance frequencies over wide bands, one varactor diode was integrated between the meander patch printed on the top layer and a floating ground plane on the back layer. When applying reverse voltage, the proposed antenna is able to reach wide frequency ranges from 0.7 to 0.98GHz for F1, 1.46 to 2.02GHz for F2 and 2.23 to 2.47GHz for the new generated resonance frequency F5 (appears when applying a voltage V=9V (C=1.5pF) and more).
