This thesis explores genetic algorithm and rule-based optimization techniques used by cognitive radios to make operating parameter decisions. Cognitive radios take advantage of intelligent control methods by using sensed information to determine the optimal set of transmission parameters for a given situation. We have chosen to explore and compare two control methods. A biologically-inspired ge...

background: the positive impacts of exercise therapy on patients’ cognitive problems still remain unknown. this study was a pilot intervention to examine the effects of combined exercise on the cognitive problems of patients with multiple sclerosis (ms) in iranian ms society over 2012 to 2013.   methods : this quasi-experimental research was carried out in the form of a pretest/posttest study. ...

in this research, both resource allocation and reactive resource allocation problems in multi-server dynamic pert networks are analytically modeled, where new projects are expected to arrive according to a poisson process, and activity durations are also known as independent random variables with exponential distributions. such system is represented as a queuing network, where multi servers at ...
