This type of absolute pressure measuring sensor is used for pulse rate measurement. Polysilicon material provides a higher sensitivity when chosen as diaphragm material. Two MEMS capacitive pressure sensors with varying geometries are analyzed in Matlab simulation software. The geometries are very common having parallel plates with spring loaded. In first stage the shape of the parallel plates is circular and in second case of the parallel plate is square. During modeling of these two diffident shaped sensors, the area of parallel plates in both cases is considered as equal. Once the geometries are formed, the electromechanical analyses have been performed. It is observed that these types of pressure sensors can withstand a wide range of absolute pressure from kilo Pascals to several order of mega Pascals. In this work, Matlab environment is employed to model this sensor and accurate model is devised to study its performance. Simulation results are obtained and compared with published work of FEM (Finite Element Method) based Multiphysics simulation platform and full argument is obtained. The proposed model allows handling different parameters affecting the performance of this sensor.}, keywords = {}, url = {https://mjeer.journals.ekb.eg/article_62657.html}, eprint = {https://mjeer.journals.ekb.eg/article_62657_36044285f003bdccd3ab7ca6fec8369c.pdf} } @article { author = {ElKamchouchi, Hassan and Khalil, Ahmed and Darwish, Samy}, title = {High Density Noise Removal in Endangered Silent- Films Using Non-linear Filters: A Comparative Study}, journal = {Menoufia Journal of Electronic Engineering Research}, volume = {24}, number = {1}, pages = {19-42}, year = {2015}, publisher = {Menoufia University, Faculty of Electronic Engineering}, issn = {1687-1189}, eissn = {2682-3535}, doi = {10.21608/mjeer.2015.62658}, abstract = {The loss and distortion of the feature films at films silent-era constitutes an alarming in cultural recording for most nation's. So the first directive of congress library was to support archival research projects that would restore the American movies produced during the 19th and 20th centuries. Noise removal is an important task in video restoration where the "original" video is discernible. Therefore this work contemplates to introduce an overview of some algorithms that can be used to restore the corrupted video that presented in AVI container format. These algorithms are untrimmed decision based median filter (UDBMF), decision based median filter (DBMF), weighted median filter (WMF), and standard median filter (SMF). A comparable analysis among all filters was done at different levels of noise based on some calculated parameters as mean square error (MSE), mean absolute error (MAE), image enhancement factor (IEF), peak signal to noise ratio (PSNR), and correlation ratio (CORR). Simulation results indicate that DBMF and UDBMF have superior performance compared to other nonlinear filters for noise level up to ninety percent. Also the necessary details in video were preserved.}, keywords = {}, url = {https://mjeer.journals.ekb.eg/article_62658.html}, eprint = {https://mjeer.journals.ekb.eg/article_62658_d9ac7978b35f66c5542022b17f25699e.pdf} } @article { author = {Dessouky, Mohamed M. and Elrashidy, Mohamed A. and Taha, Taha E. and Abdelkader, Hatem M.}, title = {Statistical Analysis of Alzheimer ’s disease Images}, journal = {Menoufia Journal of Electronic Engineering Research}, volume = {24}, number = {1}, pages = {43-66}, year = {2015}, publisher = {Menoufia University, Faculty of Electronic Engineering}, issn = {1687-1189}, eissn = {2682-3535}, doi = {10.21608/mjeer.2015.64123}, abstract = {; "> Alzheimer's disease is the most common type of dementia whichhas no cure nor imaging test for it. Diagnosis of the Alzheimer’sdisease (AD) still a challenge and difficult. An early diagnosis forAlzheimer’s disease is very important to delay the progression of it.This paper extract and analyze various important statisticalfeatures of MRI brain medical images to provide better analysis todiscriminate among the different types of tissue and diagnose ofAD. These statistical features had been used for detection of theabnormalities among different demented and non-demented MRIAD images. Also, it investigates and builds up an efficientComputer Aided Diagnosis (CAD) system for AD to assist themedical doctors to easily diagnose the disease. Statistical,structural, and textural features had been calculated for differentimages and classified using the SVM classifier. In addition, thispaper proposes an algorithm to improve the performance of theCAD system. The performance of the CAD system based onstatistical analysis and the proposed algorithm had been measuredusing different metric parameters. The obtained results indicatethat the accuracy improved from 49% without using the proposedalgorithm to 100% using the proposed algorithm.}, keywords = {}, url = {https://mjeer.journals.ekb.eg/article_64123.html}, eprint = {} } @article { author = {El-Mashed, Mohamed G. and El-Rabaie, S.}, title = {Advanced Relay Station for LTE-A Downlink Physical Layer}, journal = {Menoufia Journal of Electronic Engineering Research}, volume = {24}, number = {1}, pages = {67-78}, year = {2015}, publisher = {Menoufia University, Faculty of Electronic Engineering}, issn = {1687-1189}, eissn = {2682-3535}, doi = {10.21608/mjeer.2015.64128}, abstract = {Relay Station (RS) enhance the performance of cellular system at cell edge.
