the most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy by the effect of coupling between electric fields and mechanical variables. using piezoelectric cantilevers is the most common method for vibration energy harvesting. changing the shape of the cantilevers can lead to changing the generated output v...

In this paper, we present the analytical expression of phase-controlled class-D inverter at any duty ratio. By considering the body-diode of MOSFET effects and harmonic components of resonant current, analytical expression of phase-controlled class-D inverter at any phase shift and any duty ratio can be obtained. The validity of the analytical expression was confirmed by PSpice simulation.

We derive a new expectation maximization algorithm for policy optimization in linear Gaussian Markov decision processes, where the reward function is parameterized in terms of a flexible mixture of Gaussians. This approach exploits both analytical tractability and numerical optimization. Consequently, on the one hand, it is more flexible and general than closed-form solutions, such as the widel...

This paper proposes a new analytical model of PCS in torus in the presence of hot spot traffic pattern. Results from simulation experiments show close agreement with those predicted by the analytical model.

It has always been desired to simulate a network so as to be able to study its different performance characteristics under various operating conditions. This work presents an integrated MATLAB ® based simulation model capable of evaluating cell loss rate which is an important QoS parameter in multimedia networks such as ATM networks. The integrated model combines both the simulation and analyti...

The problem of providing a hybrid wired/wireless communications for factory automation systems is still an open issue, notwithstanding the fact that already there are some solutions. This paper describes the role of simulation tools on the validation and performance analysis of two wireless extensions for the PROFIBUS protocol. In one of them, the Intermediate Systems, which connect wired and w...

Nowadays, effective and competitive company operation can be achieved through incorporating the concept of supply chain operation into company management. Inventory control, as a critical part of the supply chain management, becomes the second most frequent application area for simulation technique in logistics (after manufacturing). The dynamics of supply chain operation is characterised by th...

Precision of trait estimation and determination of item exposure rates are always important considerations in conducting CATs. To date, simulation techniques have been used in research concerning these two considerations. Even though conducting simulation studies has some advantages over using real human subjects, the simulation results are not as accurate as analytically obtained results. To i...
