In recent years, many high speed congestion control algorithms have been proposed for utilizing network pipes with large bandwidth-delay product, and some of them have also been implemented in popular operating systems. Since the Internet is and tends to be lightly-loaded and there are many bandwidth-greedy applications, high speed congestion control algorithms may be used by many flows of the ...

Nepenthes alata-inspired micro/nano-textured lubricant-infused surface (LIS) has shown strong potential in the fields of drag reduction (DR), anti-biofouling, and self-cleaning. However, its surface-slippery property is largely degraded under turbulent shear flow conditions due to loss impregnated oil. This condition inhibits practical applications marine vehicles. The mucus-impregnated tissue ...

Traffic sampling technology has been widely deployed in front of many high-speed network applications to alleviate the great pressure on packet capturing.Increasingly passive traffic measurement employs sampling at the packet level. Packet sampling has become an attractive and scalable means to measure flow data on high-speed links. However, knowing the number and length of the original flows i...

TCP Reno congestion control carries two issues. First, its performance is poor in high-speed networks. To solve this TCP Reno drawback, HighSpeed TCP and Scalable TCP were proposed. However, the fairness between these proposed TCP and TCP Reno is not considered, when both connections coexist. Second, TCP Reno connections share bandwidth unfairly, when TCP flows with different RTTs use the same ...

Atmospheric flows are characterized by a large range of length scales as well as strong gradients. The accurate simulation of such flows requires numerical algorithms with high spectral resolution, as well as the ability to provide nonoscillatory solutions across regions of high gradients. These flows exhibit a large range of time scales as well—the slowest waves propagate at the flow velocity ...

To facilitate warning of low-level wind shear associated with convective storms, a Terminal Doppler Weather Radar (TDWR) was installed about 12 km to the northeast of the Hong Kong International Airport (HKIA). The HKIA is located just off the northern shore of an island known as Lantau. The HKIA lies on the lee side of the complex terrain of Lantau when winds come from the east through southwe...

scaling challenges and limitations of conventional silicon transistors have led the designers to apply novel nano-technologies. one of the most promising and possible nano-technologies is cnt (carbon nanotube) based transistors. cnfet have emerged as the more practicable and promising alternative device compared to the other nanotechnologies.  this technology has higher efficiency compared to t...
