The safety of electric vehicles has the highest priority because it helps contribute to customer confidence and thereby ensures further growth of the electromobility market. Therefore in series production redundant hardware concepts like dual core microcontrollers running in lock-step-mode are used to reach ASIL D safety requirements given from the ISO 26262. Coded processing is capable of redu...

in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...

Redundancy allocation problem is one of most important problems in reliability area. This problem involves with the suitable redundancy levels under certain strategies to maximizing system reliability under some constraints. Many changes have been made on this problem to draw the problem near to real situations. Selecting the redundancy strategy, using different system configuration are some of...

The time-triggered System-on-a-Chip (SoC) architecture provides a generic multicore system platform for a family of composable and dependable giga-scale SoCs. It supports the integration of multiple application subsystems of different criticality levels within a single hardware platform. A pivotal property of the architecture is the integrated error containment, which facilitates modular certif...

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...

In an earlier paper, we proved a strong version of the redundancy-capacity converse theorem of universal coding, stating that for `most' sources in a given class, the universal coding redundancy is essentially lower bounded by the capacity of the channel induced by this class. Since this result holds for general classes of sources, it extends Rissanen's strong converse theorem for parametric fa...

Retroviruses and many retrotransposons are flanked by sequence repeats called long terminal repeats (LTRs). These sequences contain a promoter region, which is active in the 5' LTR, and transcription termination signals, which are active in the LTR copy present at the 3' end. A section in the middle of the LTR, called Redundancy region, occurs at both ends of the mRNA. Here we show that in the ...

In this paper, a special class of redundancy optimization problem with fuzzy random variables is presented. In this model, fuzzy random lifetimes are considered as basic parameters and the Er-expected of system lifetime is used as a major type of system performance. Then a redundancy optimization problem is formulated as a binary integer programming model. Furthermore, illustrative numerical ex...
