Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3...

Computation of active and reactive powers is a crucial step in droop-controlled single-phase voltage source inverters (VSIs) standalone microgrid since the performance stability power-sharing strategy are strongly influenced by its speed accuracy, especially case non-linear loads. Here, an improved among VSIs islanded microgrid, considering DC component nonlinear loads presented. To achieve thi...

Considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significant importance. In this study, we consider one of the current models of the reliability science and propose a non-linear programming model for redundancy allocation in the series-parallel systems according to the redundancy strategy and considering the assump...

With the huge global and wide range of attention placed upon quality, promoting and optimize the reliability of the products during the design process has turned out to be a high priority. In this study, the researcher have adopted one of the existing models in the reliability science and propose a bi-objective model for redundancy allocation in the series-parallel systems in accordance with th...

In recent years, two important events have occurred in the area of high-performance computing: the development of very high speed processors, and the development of massively parallel computers based on these processors. The processing capacities of these parallel computers have made them the computational instrument of choice in the scientific community and they can be found in one form or ano...
