In this paper,we propose a new linear multiuser receiver for synchronous code-division multiple-access (CDmA) systems,referred to as the orthogonal multiuser(OmU) *** the linear minimum mean-squared error(mmSE) receiver,the OmU receiver depends only on the signature vectors and does not require knowledge of the received amplitudes or the channel signal-to-noise ratio(SNR).Here we develop methods that construct an optimal set of vectors with a specified inner product structure,from a given set of vectors in a complex Hilbert *** optimal vectors are chosen to minimize the sum of the squared norms of the errors between the constructed vectors and the given *** algorithm has been developed using the principles of quantum parameters and some of its axioms and *** place of the classical matched filter(mF) receiver we propose a modified *** approach assumes that improving the accuracy will necessarily result in im- proved *** simulation results provided here suggests that in certain cases the OmU and POmU receivers can significantly increase the probability of correct detection with low error rate over the mF receiver.

Emerging Trends in the Etiology and Antimicrobial Susceptibility Pattern of Enteric Pathogens in Rural Coastal India

International Journal of Clinical medicine 2014年第7期5卷 425-432页

Introduction: Gastroenteritis is recognized as a serious public health problem in India. It is a syndrome that can be caused by different bacterial, viral and parasitic pathogens. Indiscriminate use of antibacterial agents has resulted in the development of multidrug resistant organisms. A retrospective study was done to analyze the etiological spectrum of diarrhoea and to determine the antimicrobial resistance pattern of bacterial pathogens. methodology: Fecal specimens from patients with acute or chronic diarrhoea were received prior antibiotic administration and processed for routine microscopy of parasites;culture, antimicrobial susceptibility testing and polymerase chain reaction for bacterial pathogens and latex agglutination for rotavirus. Results: Out of the 6043 stool samples collected during the period of Jan 2005-Dec 2013, 678 (11.2%) enteric pathogens were isolated. The predominant isolates were Diarrheagenic Escherichia coli (DEC) (46.3%) followed by Salmonella, Shigella, Vibrio cholerae and parasites. Certain unusual pathogens were also isolated. Among age wise distribution, Diarrheagenic Escherichia coli (DEC) mainly Enteroaggregative Escherichia coli (EAEC) was isolated from majority of other enteric pathogens were isolated from the adult population. The enteric pathogens isolated showed resistance to multiple antibiotics. The resistance pattern observed during this period showed an overall increase in resistance to the antibiotics tested. Conclusion: The present study documents the overall role of etiological agents as causes of diarrhoea and indicates that the indiscriminate use of potent antibiotics can lead to acquisition of resistance to important therapeutic agents.

考察了复合式膜生物反应器(HmBR),即电絮凝、生化和微滤过程,对制革污水中的COD和色度的去除效果。分析了电流密度和pH值在电絮凝过程中的影响,并优化了电絮凝过程。将优化后的电絮凝过程和活性污泥法(ASP)、末端微滤(mF)相结合,应用于制革污水处理中。结果表明:复合过程可以有效提升污水的处理质量。对比膜生物反应器(mBR)和HmBR的处理效果,HmBR的最大COD去除率和脱色率分别为90.2%和92.75%,而mBR的最大COD去除率和脱色率分别为72.69%和75.82%。使用SEm-EDAX分析HmBR过程中附着在膜表面的滤饼层,表明将mBR和电絮凝法结合后,膜上的污垢显著减少。
