In this work we propose to use an approach based on genetic algorithms to obtain analytical redundancy relations to study the diagnosability property on a given continuous production system. Diagnosability analysis for production systems examines the detectability property (the faults are discriminable from the normal behavior of the system) and the isolability property (the faults are discrimi...

Random Access Memory is major component in present day SOC, by Improving the yield of RAM improves the yield of SOC. So the repairable memories play a vital role in improving the yield of chip. Built-in self-repair (BISR) technique has been widely used to repair embedded random access memories (Ram's). If each repairable RAM uses one self contained BISR circuit (Dedicated BISR scheme), then the...

This study considers the case of unreliable equipment subjected to random failures that induce high maintenance and environmental costs. We consider situations where is located in remote areas, which are difficult access, there could be confinement linked a pandemic, making it impossible perform replacement failed equipment. In such situations, objective explore possibility providing system wit...

optimization of maintenance resources to maximize the system availability is a major concern in different manufacturing systems. therefore, a lot of effort is put to construct optimization models to reach the maximum availability level and to reduce the costs of lack of availability. however, despite these efforts, data uncertainty in the real world problems was neglected in proposed models whi...

Actuarial senescence is characterized by an increase in mortality rate with increasing chronological age. The reliability theory of senescence proposes that organisms' vital functions can be modelled as a suite of damageable, irreplaceable elements (typically genes or their products) that protect their bearer from condition-dependent death so long as at least one of the elements remains intact....

This Letter proposes energy-efficient error control for IEEE 802.15.1 (Bluetooth) video communication. The scheme is based on block-oriented incremental redundancy provided by rateless coding and receiver feedback. Results are presented for time-sensitive video streaming applications under a Markovian channel model. When the proposed algorithm is compared to variations of Bluetooth Forward Erro...

One of the reasons for the suitability of electric propulsion for OSVs is the large variations in the load profile of propulsors and thrusters. Total engine capacity has to be dimensioned to achieve the design speed of the vessel, or the dynamic positioning (DP) capability in the worst weather situations. As most newbuild vessels are classified as DP 2, with redundancy requirements, the total i...

To increase the reliability of a specific system, using redundant components is a common method which is called redundancy allocation problem (RAP). Some of the RAP studies have focused on k-out-of-n systems. However, all of these studies assumed predetermined active or standby strategies for each subsystem. In this paper, for the first time, we propose a k-out-of-<em...

This study investigated electroencephalographic correlates in chronically depressed patients compared to healthy controls using intracutaneously applied electrical pain stimulus, to better understand the interaction between pain processing and depression. A close interaction between pain and depression is generally recognized although the precise mechanisms are not yet fully understood. The pre...
