Fine-grained frequencies have been used for IEEE 802.15.4 based communication in several recent works to enhance network throughput as well combat Cross Technology Interference (CTI) licence free ISM bands. However, the demonstrate that Center Frequency Distance (CFD) goes very low (<3 MHz), adjacent channels start severely interfering with each other which heavily limits use of fine-grained fr...

The use of constraint propagation is the main feature of any constraint solver. It is thus of prime importance to manage the propagation in an efficient and effective fashion. There are two classes of propagation algorithms for general constraints: fine-grained algorithms where the removal of a value for a variable will be propagated to the corresponding values for other variables, and coarse-g...

While the Differentiated Services (DiffServ) infrastructure is scalable and robust in providing network Quality of Service (QoS), there are serious drawbacks with the services provided by DiffServ: (1) the services are coarse-grained and oneway only; (2) no service differentiation and resource isolation are provided to meta-data packets such as TCP SYN and ACK packets. Moreover, the coarse-grai...

austenitic stainless steels are extensively used in various applications requiring good corrosion resistance and formability. in the current study, the formation of nano/ ultrafine grained austenitic microstructure in a microalloyed aisi 304l stainless steel was investigated by the advanced thermomechanical process of reversion of strain-induced martensite. for this purpose, samples were subjec...
