Error exponents for multipath fading channels : a strong coding theorem
… are exponentially tight and therefore yield the reliability function. We study the behavior of the reliability function and the upper and lower error probability bounds numerically.

Bayes and minimum variance unbiased estimators of reliability using the truncated Weibull life testing model
… theory has become widely used in the study of reliability. In this study, we shall consider two types of estimators, namely, the Bayes and minimum variance unbiased estimators for the scale parameter θ in the truncated Weibull life testing model when the shape parameter ρ assumed known. In …

Broadband Fading Channels: Signal Burstiness and Capacity
… cost is generalized to a fourth-order functional called fourthegy which depends on the square of the signal ambiguity function. The capacity per unit fourthegy for WSSUS channels is identified and is finite and nonzero. It follows that signals with small values of fourthegy per unit …

Variable block length coding for channels with feedback and cost constraints
… one in a certain asymptotic sense. A resulting reliability function is found for variable decoding time DMC's with perfect feedback under a cost constraint. The results in this work generalize Burnashev's results, to the cost constrained case.

Wireless Communications in the Energy -Limited Regime
… noncoherent fading channels and characterize the reliability function in the low-SNR regime. Further, by allowing multiple transmit and receive antennas, we study the impact of multiple antennas on the fundamental tradeoff between communication rate and probability of decoding error. For the case …

Inference for the survival function of the linearly decreasing stress Weibull
The survival function is defined as the probability that a person or an object will survive beyond a specified time point. It is used in many applications including human mortality. It is also known as the survivor function or reliability function. The Weibull distribution has long drawn the …

Time dependant redundancy optimization
Three different time-dependent optimal reliability design models with a series-parallel system are formulated. An efficient heuristic procedure for each problem is elucidated, and the results are described. The redundancy optimization problem using the time-dependent reliability function is solved …

Reliability-based Design Optimization of a Nonlinear Elastic Plastic Thin-Walled T-Section Beam
… is performed to investigate the application of reliability-based design optimization (RBDO) approach to design elastic-plastic stiffener beams with Tsection. The objectives of this study are to evaluate the benefits of reliability-based optimization over deterministic optimization, and to …

Mismatched Decoding: Capacity and Error Exponent Upper Bounds
… method is used to derive an upper bound to the reliability function. In contrast to the previous part, when a codeword is sent over the auxiliary channel and the hypothetical decoder makes an error, the mismatched decoder makes an error with a positive probability. Moreover, this probability is …

A dynamic programming approach to the multi-stream replacement problem
… the environment in which the item operates. The reliability function is used to describe the survivor probability in this population model. A dynamic repair/replace program is formulated where the state functions are characterized by two parameters - item age and current operational condition. A …

A risk analysis methodology for micro/nano manufacturing
… different types of requirements such as the reliability and cost. An optimal flip chip design reliability function is identified. The approach allows electronics manufacturers to consider the environmental impact amongst different design alternatives at an early stage of the design of the …

Estimadores bayesianos de la fiabilidad con muestreo censurado
… variables. We obtain two Bayes estimators of the reliability function of an exponential distribution based on randomly censored data. We have calculated the asymptotic expansion of the mean, variance and mean square error of both estimators, when the censor's distribution is exponential. We have …

Development and application of a microbial reliability model to analyze denitrifying biofilter stability
… the relationships between microbial diversity, functional redundancy, and ecosystem stability. A better understanding of these relationships and other factors that affect performance stability of the denitrifying biofilters is necessary to further enhance their effectiveness. With the …
