An effective approach on zero-voltage switching scheme for a single-stage grid-connected flyback inverter along with the introduction of Modified Grey Wolf Optimizer technique based proportional integral controller is proposed. A focus soft-switching attained by means permitting grid-side negative current bidirectional switches held in transformer’s secondary side. Consequently, there discharge...

Ranking is a technique to categorize & finding the best option in the market. When number of best option is available in the market so its difficult to getting the best option is always a problem. In this paper we proposed a technique to optimize the ranking and its availability to check performance factor in order to maintained high ranking and quality of popular option in the market. We enhan...

Finding extraterrestrial intelligence would calibrate humanity’s place in the cosmos. It would also complete the so-called Copernican revolution. Beginning about 470 years ago, observation and scientific reasoning led to an accurate understanding of our place in the physical universe. The goal of SETI – the Search for Extraterrestrial Intelligence – is to learn our place in the intellectual uni...

Nowadays, the growing demand for supporting multiple applications causes to use multiple IPs onto the chip. In fact, finding truly scalable communication architecture will be a critical concern. To this end, the Networks-on-Chip (NoC) paradigm has emerged as a promising solution to on-chip communication challenges within the silicon-based electronics. Many of today’s NoC architectures are based...

Spatial navigation relies on the brain ability to combine information from multiple streams in order to generate a cognitive map, which is then used, for example, to find routes to a goal. This takes place in a network of brain structures centered on the hippocampus. Hippocampal place cells, cells that activate only when the animal is in a particular location in the environment combine sensory ...

the goal of this prospective study was to determine die prevalence of certain surgical findings in iranian patients with appendicitis in one of our surgical centers, including: position of the appendix, rate of true appendicitis, perforation, and peritonitis. duplication was observed in 4%, surface exudate in 52%, gangrenous necrosis in 27%, swelling in 79%, appendix in the left lower quadrant ...
