Particle swarm optimization (PSO) and simplified (SSO) are two of the state-of-the-art intelligence technique that is widely utilized for purposes. This paper describes a particle-based (PSSO) procedure which combines update mechanisms (UMs) PSO SSO to determine optimal system reliability reliability-redundancy allocation problems (RRAPs) with cold-standby strategy while aimed at maximizing rel...

This paper presents genetic algorithms for solving various reliability design problems, which include series systems, series-parallel systems and complex (bridge) systems. The objective is to maximize the system reliability, while maintaining feasibility with respect to three nonlinear constraints, namely, cost and weight constraints, and constraints on the products of volume and weight. In thi...

Error correction codes of suitable redundancy are used for ensuring perfect data recovery in noisy channels. For iterative decoding based methods, the decoder needs to be initialized with proper confidence values, called the log likelihood ratios (LLRs), for all the embedding locations. If these confidence values or LLRs are accurately initialized, the decoder converges at a lower redundancy fa...

In this paper, the authors propose an algorithm-level time redundancy-based concurrent error detection (CED) scheme against permanent and transient faults by exploiting the hardware allocation diversity at the register transfer level. Although the normal computation and the recomputation are carried out on the same data path, the operation-to-operator allocation for the normal computation is di...

In this paper, the problem of population districting in the health system of South Khorasan province has been investigated in the form of an optimization problem. Now that the districting problem is considered as a strategic matter, it is vital to obtain efficient solutions in order to implement in the system. Therefore in this study two meta-heuristic algorithms, Ant Lion Optimizer (ALO) and G...

Many stereo image compression algorithms exploit the redundancy between the two images in a stereo pair by using disparity compensated prediction. Thus, research in coding of stereo images has focused mostly on the issue of disparity estimation, with less attention being devoted to the equally important problem of allocating bits among the two images. This bit allocation problem is complicated ...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...
