One of the structures presents right handed CP (RHCP), while the other one offers left handed CP (LHCP). A single layer of low cost printed circuit board (PCB) is employed for both antennas providing low cost, light weight and also easy integration with planar circuits. An inset microstrip line is used to excite two orthogonal modes, TE120 and TE210, with 90° degree phase difference for generating CP wave. Antenna structure is numerically evaluated using High Frequency Structure Simulator (HFSS) and results including reflection coefficient, gain, and axial ratio (AR), and radiation patterns are reported.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128778098","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}

Besides the costs involved in fabrication, duplication, and distribution of keys, there are security problems in case of lost keys. In this paper an innovative lock system prototype using today's technologies will be presented. The novelty of this prototype relies on the fact that using new technologies along with old ones will result in a smart and more efficient. We propose a smart digital door lock system for any lock system. A digital door lock system is any equipment that uses the digital information such as a secret code instead of the legacy key system. In our proposed system, a Central Control module is embedded in the door itself, this is required to prevent additional complications and more robust mechanism for the door as a whole. Technically, this system embeds itself in the Local Area Network of the house. This adds extra security layers and prevents access to the system only through the network. Furthermore, the biggest advantage of the proposed system over existing ones is that it can be easily installed with minimal requirement of infrastructures and planning.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"135 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131156874","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}

As a result, an a posteriori synthesis method was established in order to control temperature at certain functional points of the homogeneous finite diffusive interface bar while controlling the density of flux at the input boundary of this medium. Results show that the CRONE controller is robust when changing the material. As for the placement of the temperature sensor, the use of the third generation CRONE control would give better robustness.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121968394","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}

Sun, waves, winds, tides and biomass are sources of renewable energy. Nowadays, a major importance is given to renewable energy sources in order to reduce the dependence on fossil fuels that will one day be depleted. The exploit of many renewable energy sources such as sun and wind power have progressed to a relatively high level. However, sea waves are an important source of renewable energy that is not yet developed in Lebanon. For this purpose, in this paper, a wave roller energy harvesting system has been designed and manufactured. The aim of this work is to determine the drag coefficient and to perform a stress analysis on this wave roller device: a system that harvests the sea wave energy to produce electricity. This study will present the numerical results obtained using high fidelity Computational Fluid Dynamics (CFD) simulations. Also, a stress analysis study showed that the designed roller resists against the external forces predicted in the CFD study. The designed device is manufactured and tested on the Lebanese coast.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127761021","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}

An experimental measurement of longitudinal permeability is done using a closed resin transfer mold (RTM) system. Concerning the Finite element modeling, an arrangement of the fiber bundles and a unit cell is proposed. The evaluation of numerical permeability is based on a main assumption. The assumption says that the permeability of the unit cell is mainly calculated from the flow passing through gaps (between the bundles). Thus we avoid the simulation on a real unit cell with micro flow throughout the fibers. The predicted numerical results were in good agreement with the experimental data.","PeriodicalId":220936,"journal":{"name":"2016 3rd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA)","volume":"735 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126816879","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 decision that can be made is creating a stimulus to avoid falling in case of sudden stop while moving, initiating an alarm, sending a notification to a mobile phone application, and/or telemedicine monitoring features. Artificial Neural Networks will be used to classify and predict the abnormal cases where action should be taken, and since the sensors will be continuously recording, it is possible to achieve continuous learning for the ANN as a first phase.
