Apart from burst loss modeling, it faces the same network impairments as the fast-class source in the connection model in Fig. 2. Analyzing the performance of the direct- source connection will be useful to validate the effectiveness of the Bernoulli-distributed loss model in Section B. ...
Consensus problems have a long history in the eld of computer science, particularly in automata theory and distributed computation [11]. In many applications involving multiagent/multivehicle systems, groups of agents need to agree upon certain quantities of interest. Such quantities might or might ...
In general. switching 'action introduces both zeros and poles into the duty ratio to output transfer function. in addition to the zeros and poles of the effective filter network which essentially constitute the line voltage to output transfer function. Moreover, in general. both duty-ratio ...
