A fully adaptive router with hybrid buuers at the input and output channels was designed, which improves the throughput of its input buuer counterpart by up to 40% and has only 10% higher base la-tency. An in-depth analysis of diierent router buuer organization was carried out for a toroidal network, which uses either a deterministic (DOR) or a fully adaptive routing scheme. Each proposal is de...

gully erosion is one of the most severe types of water erosion that inclusive and global model to represent its development under different environmental circumstances is difficult. moreover, having knowledge about history behaviors of a gully and its advancement requires direct annual monitoring that is not possible in iran conditions because of cost and time. gis and remote sensing with provi...

In the metropolitan area, traditional SONET/SDH circuit switched rings are likely to be replaced with optical packet/burst switching technologies. In this paper we consider a slotted WDM optical packet ring operating without resource reservation mechanisms. In such rings, optical packets in transit have priority over traffic to be inserted by the node. Packets to be inserted are thus queued acc...

A primary design decision in HTTP/2, the successor of HTTP/1.1, is object multiplexing. While multiplexing improves web performance in many scenarios, it still has several drawbacks due to complex cross-layer interactions. In this paper, we propose a novel multiplexing architecture called TM that overcomes many of these limitations. TM strategically leverages multiple concurrent multiplexing pi...

wheat is grown on 6.2 million hectares under different agr-climate conditions in iran. of 6.2 million hectares irrigated wheat, khazar warm humid climate regions (gorgan, mazandaran and moghan) with 350 thousand hectares are the most important wheat growing areas of the country. productive and rich lands, high rainfalls and favorable temperature and light in these regions provide good condition...
