The error probability floor evolves due to performance loss, thus there is a requirement of high energy and high bandwidth to get a desired link. The branches are assumed to be Rayleigh fading. With the increase number of receiver the signal to noise ratio to be improved and bit error rate of all branches are compared. This work confirms the benefit of choosing 2x2MIMO system instead of 1 trans...

Concurrent coding is an encoding scheme with 'holographic' type properties that are shown here to be robust against a significant amount of noise and signal loss. This single encoding scheme is able to correct for random errors and burst errors simultaneously, but does not rely on cyclic codes. A simple and practical scheme has been tested that displays perfect decoding when the signal to noise...

When a data transmission is made by a communication network, the maximum frame size is limited according to physical parameters such as signal to noise ratio, bit error rate or even the channel distance. However, the maximum size is programmed manually in the network equipment with preconfigured small values, although IPV6 allows jumbograms transmission of packets larger than 64KB. This paper e...

In January 2003, St. Mary's Hospital Center in Montreal, Quebec, established an interdisciplinary Committee on the Systematic Approach to Medication Error Control to review the whole process of medication administration within the hospital and to develop a systematic approach to medication error control. A cross-sectional survey on medication administration practices, perceived sources of error...

INTRODUCTION The objective of our study was to estimate the incidence of prescribing medication errors specifically made by a trainee and identify factors associated with these errors during the simulated resuscitation of a critically ill child. METHODS The results of the simulated resuscitation are described. We analyzed data from the simulated resuscitation for the occurrence of a prescribi...

This work is concerned with tracking and system identification for time-varying parameters. The parameters areMarkov chains and the observations are binary valuedwith noise corruption. To overcome the difficulties due to the limited measurement information, Wonham-type filters are developed first. Then, based on the filters, two popular estimators, namely, mean squares estimator (MSQ) andmaximu...

abstract   background : noise is the most common hazard in the workplace and noise induced hearing loss considered to be the most common occupational disease as well. cigarette smoking, in some studies, has been known to induce hearing loss. the purpose of this study was to evaluate the effect of contemporary exposure to occupational noise and cigarette smoking on hearing.   methods : 478 assem...

Tensor completion from incomplete observations is a problem of significant practical interest. However, it is unlikely that there exists an efficient algorithm with provable guarantee to recover a general tensor from a limited number of observations. In this paper, we study the recovery algorithm for pairwise interaction tensors, which has recently gained considerable attention for modeling mul...

The performance of Neyman-Pearson detection of correlated stochastic signals using noisy observations is investigated via the error exponent for the miss probability with a fixed level. Using the statespace structure of the signal and observation model, a closed-form expression for the error exponent is derived, and the connection between the asymptotic behavior of the optimal detector and that...

Improvements of TCP performance in wireless networks have been tossed around for several years. One mechanism that has received considerable attention is the use of error recovery techniques thereby compensating for the wireless loss characteristics. However, surprisingly, to our knowledge no study in error avoidance has been carried out. This paper proposed the use of an error avoidance scheme...
