Assume a local simulator (LS) of a given system is available and we wish to turn it into a distributed simulator (DS). In the DS case, the LS is partitioned into segments called federates, each federate being run by a separate host. Before implementing the DS (i.e., at design-time) we wonder: will the DS execution time be shorter than LS one? In some cases the DS may run slower than the equival...
The continuous-time quantum walk is a basic model for studying transport and developing quantum-enhanced algorithms. Recent studies show that by introducing phase into the standard model, time-reversal symmetry can be broken without changing Hermitian property of Hamiltonian. breaking shows advantages in transport, such as perfect state transfer, directional control, speedup, efficiency enhance...
The time consumption in solving computationally heavy problems has always been a concern for computer programmers. Due to simplicity of its implementation, the PSO (Particle Swarm Optimization) is a suitable meta-heuristic algorithm for solving computationally heavy problems. However, despite the simplicity, the algorithm is inefficient for solving real computationally heavy problems but the pr...
RTT has been widely used as a metric for peer/server selection. However, many applications involving closest peer/server selection like streaming, tree-based multicast services and other UDP and TCP based services would benefit more from knowing one-way delay (OWD) rather than RTT. In fact, RTT is a compromise solution in most cases and is used to infer forward and reverse delays by many protoc...
In high-speed switches the Input Queued(IQ) architecture is very popular due to its low memory-bandwidth requirement compared to the Output Queued (OQ) switch architecture which is extremely desirable in terms of performance but requires very high memory-bandwidth. In the past decade researchers and industry people have been trying hard to £nd good scheduling algorithm for IQ switches. The two ...
Introduction: In this study, the effect of memantine administration into the nucleus accumbens on the metabolic changes induced by acute stress in female mice was evaluated. Methods: Intra-accumbens unilateral or bilateral canulation was performed. One week after recovery, a group of animals were given memantine (1, 0.5, and 0.1 μg/mouse) five min before stress induction intra-accumbally, an...
We analyze a class of models for unequal crossover (UC) of sequences containing sections with repeated units that may differ in length. In these, the probability of an 'imperfect' alignment, in which the shorter sequence has d units without a partner in the longer one, scales like qd as compared to 'perfect' alignments where all these copies are paired. The class is parameterized by this penalt...
The demands of precise time/phase synchronization have been increasing recently due to the next generation of telecommunication synchronization. This paper studies the issues that are relevant to distributing accurate time/phase over optical transport network (OTN). Each node and link can introduce asymmetry, which affects the adequate time/phase accuracy over the networks. In order to achieve ...
