IEEE 802.15.4 is the standard wireless link technology for low power, low cost, low data-rate, but long lifetime applications including wireless sensor network (WSN). Currently, whether or not IP architecture should be used in WSN over its 802.15.4 link is under dispute. One view is that IP architecture is not suitable for WSN; instead ad hoc network architecture is more preferred to be designe...

In communication networks (CNs), the uncertainty is caused by the dynamic nature of the traffic demands. Therefore there is a need to incorporate the uncertainty into the network bandwidth capacity design. For this purpose, this paper developed a fuzzy methodology for network bandwidth design under demand uncertainty. This methodology is usually used for offline traffic engineering optimization...

The improvement of the communication systems is conducted through communication protocol engineering and optimization process. This paper presents an effort to upgrade the IEEE 802.16 and IEEE 802.16e protocol performance regarding the delay during subscriber network entry or base station handover. Our communication protocol engineering process of WiMax protocol and its optimization resulted in...

The literature review reveals there is a wide variation of approaches in applying the concepts of evaluation. In this first article, the principles of clinical evaluation have been discussed and subsequently applied to the unique educational situation involved in a nurse anesthesia educational program. The effectiveness of any evaluation program can be determined only after implementation, use ...

in this paper, a complete model of an electro hydraulic driven dry clutch along with its performance evaluation has elucidated. through precision modeling, a complete nonlinear physical and full order sketch of clutch has drawn. ultimate nonlinearities existent in the system prohibits it from being controlled by conventional linear control algorithms and to compensate the behavior of the system...

Workforce development programs in public health should link improvements in workers' performance with improvements in their agencies' performance. The "ten essential services" of public health provide criteria for measuring both individual worker training (as in workforce competency standards) and agency performance (as in the Centers for Disease Control and Prevention's National Public Health ...
