Vehicular cloud (VC) is a promising technology for processing computation-intensive applications (CI-Apps) on smart vehicles. Implementing VCs over the network edge faces two key challenges: (C1) On-board computing resources of single vehicle are often insufficient to process CI-App; (C2) The dynamics available resources, caused by vehicles’ mobility, hinder reliable CI-App processing. This wor...

The paper presents a simulation-based study of topological characteristics of a mobile wireless ad-hoc network with unreliable nodes. The characteristics studied are connectivity, coverage, maximum inter-node distance and node degree. Knowledge of these characteristics aids in the design of new distributed protocols as well as in predicting the performance and robustness of current protocols ex...

There are two effective ways to maintain the system to perform a high or required level of reliability and availability: one is spare units for key units; the other is several maintainers for the system. To solve reliability indexes of complex mechanical system under these assumptions, a system model was established, which consists of two dissimilar subsystems in series and each subsystem is wa...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

All genomes require a system for avoidance or handling of collisions between the machineries of DNA replication and transcription. We have investigated the roles in this process of the mTERF (mitochondrial transcription termination factor) family members mTTF and mTerf5 in Drosophila melanogaster. The two mTTF binding sites in Drosophila mtDNA, which also bind mTerf5, were found to coincide wit...

Two, ASENs and ZTNs, fault-tolerant multistage interconnection networks of different class are compared, based on their analytic bounds of MTTF, cost, and cost-effectiveness. The full-access condition and deadfault model are used for the MTTF analysis. The simulation study reveals that ZTNs are better in terms of cost and cost-effectiveness while both networks are equally reliable in terms of u...

In this paper, a comprehensive formulation of reliability models for active and passive power components (i.e., capacitors semiconductor devices (MOSFETS)) regulated transformer rectifier unit (RTRU) more electric aircraft application is presented. Additionally, the work focuses on analysis evaluation at system level non-modular discrete MOSFET based auxiliary supply more-electric-aircraft. A r...
