Research ArticleOpen accessEvery word in the titlePerformance of MMSE Receiver based Multi Input Multi Output-Interleave Division Multiple-Access System with Multi-user Detection over Frequency Selective Wireless Communication ChannelKuttathatti Srinivasan Vishvaksenan, R. SeshasayananProblem statement: This study presents the performance analysis of turbo assisted Interleave Division Multiple-Access (IDMA) system with Multi Input Multi Output (MIMO) support for multi user scenario over correlated frequency selective and uncorrelated frequency selective channel. Approach: The key principle of IDMA is that interleaver unique which distinguishes the users in contrast to spreading sequence in Code Division Multiple Access … …Journal of Computer Science, Vol. 7, Issue 7 · 30 Jun 2011 · 6,834 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Video Surveillance System Based on Multimedia Messaging ServiceS. Chandramathi, N. Chandra Sekhar, M. G. AdarshToday’s communication world ensures that anybody can communicate to anyone anywhere anytime across the globe. The new mobile communication systems include not only voice but also data and video messages. Natural way to communicate is to send and receive messages. Multimedia messaging are essential drivers for continuous growth in new services beyond voice. In this study, multimedia messaging services available … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,914 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVLSI Implementation of Channel Estimation for MIMO-OFDM TransceiverJoseph Gladwin Sekar, Salivahanan SankarappanIn this study the VLSI architecture for MIMO-OFDM transceiver and the algorithm for the implementation of MMSE detection in MIMO-OFDM system is proposed. The implemented MIMO-OFDM system is capable of transmitting data at high throughput in physical layer and provides optimized hardware resources while achieving the same data rate. The proposed architecture has low latency, high throughput and efficient resource … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 6 Sep 2013 · 6,550 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAssessment of Risk of Falls in Elderly Patients with Osteoarthritis of the Knee and Low Back PainVictor Hugo do Vale Bastos, Marco Antonio Araujo Leite, Marco Orsini et al.This study aimed identify which groups of elderly are at higher risk of falls, with osteoarthritis (OA), low back pain or both conditions. 29 elderly were distributed in three groups: OA of the Knee (OAK), Low Back Pain (LBP) and the two events concomitantly (OL). Evaluation tools applied were: Mini Mental State Examination (MMSE), Visual Analogue Scale (VAS), Western Ontario … …Current Research in Medicine, Vol. 3, Issue 2 · 30 Aug 2012 · 7,271 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Comparative Performance Analysis of Multiple-Input Multiple-Output using MATLAB with Zero Forcing and Minimum Mean Square Error EqualizersBara'u Gafai Najashi, Tan XiaohengProblem statement: Multiple-Input Multiple-Output systems (MIMO) were regarded as one of the most promising technologies in field of wireless communication. Generally considered as one of the several forms of smart antenna technology, it offers considerable increase in data throughput and link range without additional bandwidth or transmit power. The general idea involves the use of several antennas at the transmitter … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 29 Nov 2011 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Modification of the Ridge Type Regression EstimatorsMoawad El-Fallah Abd El-SalamProblem statement: Many regression estimators have been used to remedy multicollinearity problem. The ridge estimator has been the most popular one. However, the obtained estimate is biased. Approach: In this stuyd, we introduce an alternative shrinkage estimator, called modified unbiased ridge (MUR) estimator for coping with multicollinearity problem. This estimator is obtained from Unbiased Ridge Regression (URR) in the same … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,638 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSpeech Enhancement Using Minimum Mean-Square Error Amplitude Estimators Under Normal and Generalized Gamma DistributionChabane Boubakir, Daoud BerkaniProblem statement: In this study, DFT-based speech enhancement via Minimum Mean-Square Error (MMSE) amplitude estimators was considered. Approach: Several variants of the basic approach (MMSE-STSA) have been proposed over the years to address certain shortcomings, chiefly the quality of the remnant noise and its trade-off with speech distortion. In this study, we presented a comparative study between the MMLSA and … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Atorvastatin on Oxidized Low-Density Lipoprotein-induced Proliferation, Apoptosis, and Matrix Metalloproteinase-9 Expression in Human MacrophagesBensheng Liu, Huifan Li, Yan Wang, Li ZhangAtorvastatin (ATV), an HMG-CoA reductase inhibitor, is utilized in the treatment of atherosclerotic diseases. Mononuclear Macrophages (MMs) are critical immune cells involved in atherosclerosis progression, participating in processes such as foam cell formation, cytokine secretion, and the development of fibrous cap and lipid core. To further elucidate the mechanism by which ATV exerts its therapeutic effects on atherosclerosis through the … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 18 Nov 2025 · 2,133 accessesView PDFCite

Nazrul IslamArial Khan River is right bank distributary of Ganges-Padma River systems flowing southwest region of Bangladesh. It is morphologically very dynamic meandering river: where the delta-building process is more active than other distributaries of Ganges-Brahmaputra-Meghna (GBM) River basin. This study analyzes, morphological variables- channel length, valley length, channel area and channel patterns of Arial Khan River. A major portion of … …Current Research in Geoscience, Vol. 8, Issue 1 · 16 Nov 2018 · 9,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal and Psychological Factors-Does it Impact the Choice of Advertising Medium?Izian Idris, Mohd Shukri Ab Yajid, Ali KhatibiProblem statement: Advertising is a multidimensional phenomenon that has been studied in several disciplines.
