Simulation is experimentation with a model. The behavior of the model imitates some salient aspect of the behavior of the system under study and the user experiments with the model to infer this behavior. This general framework has proven a powerful adjunct to learning, problem solving, and design. In this tutorial, we focus principally on discrete-event simulation—its underlying concepts, structure,...
SSDs support various type of parallel IO mechanism. Thus, simulating IO latency of SSDs is difficult. In this paper, we develop SSD IO latency model for multi-channel, multi-way SSD. With the IO latency model, An SSD simulator can generate IO latency with a single thread. The IO latency models has 4% error rate compared with a real SSD, Intel X25-M.
In this paper the Small Signal Discrete-time Model for Active Clamp Forward Converter is proposed by using state space averaging technique to design a digital controller, takes in to consideration of modulator effects and delays in the control loop. The validity of the designed model and achievement of desired compensation for Active Clamp Forward Converter with digital controller is confirmed by...
In this paper, we propose a mixed preemptive and non-preemptive resume priority (PRP/NPRP) M/G/1 queueing model for the modeling of the traffic in Cognitive Radio (CR) Networks with prioritized transmissions. A traffic-adaptive spectrum handoff scheme is then developed based on the proposed queueing model for delay sensitive applications. This spectrum handoff scheme reduces the delivery time of the...
We present a decentralized, communication-less approach to the dynamic allocation of a swarm of homogeneous robots to a target distribution among multiple sites. Building on our work, we optimize stochastic control policies for the robots that cause the population to quickly redistribute among the sites while adhering to a limit on inter-site traffic at equilibrium. We propose a way to account for...
