The problem of optimal switching and control of nonlinear switching systems with controlled subsystems is investigated in this study where the mode sequence and the switching times between the modes are unspecified. An approximate dynamic programming based method is developed which provides a feedback solution for unspecified initial conditions and different final times. The convergence of the ...

With the advancement of battery technology, energy harvesting communication systems attracted great research attention in recent years. However, energy harvesting communication systems with multiple transmitters and multiple receivers have not been considered yet. In this paper, the problem of broadcasting in a communication system with multiple energy harvesting transmitters and multiple recei...

in this research we have presented a local model for implementing systems engineering activities in optimized acquisition of electronic systems in electronic high-tech industrial. in this regard, after reviewing the literature and the use of documents, articles and latin books, we have collected system acquisition life cycle models from different resources. after considering the criteria of the...

VAR support should be supplied as close to the load as possible to minimize transmission losses. For voltage control and for improvement of total power factor in a distribution system the circuit- breaker switched capacitor banks can be used. The problems with this solution are the voltage steps caused by the large sizes of the capacitor banks as well as the transients caused on insertion. Thyr...

Photonic packet switches can offer high data rates and format transparency as required by future communication system. Although electronic technology can achieve high switching speed, it is not compatible with the transmission bandwidths of the fiber-optic links. This paper is concerned with alloptical time division multiplexing router based on all-optical switching device. Three terahertz opti...

Reversible resistive switching induced by an electric field in oxide-based resistive switching memory shows a promising application in future information storage and processing. It is believed that there are some local conductive filaments formed and ruptured in the resistive switching process. However, as a fundamental question, how electron transports in the formed conductive filament is stil...

Ultra-high capacity optical interconnection networks capable of supporting data rates of terabits per second per port, are considered as a potential solution to the immense processor-memory access communications bottleneck expected to dominate high-performance petaflop-scale supercomputers. All-optical switches have the potential to supply this next -generation technology with the performance c...

A molecular junction formed by a 10-15 Å organic monolayer between carbon and mercury contacts exhibited conductance switching for several monolayer structures. When the carbon potential was scanned to a sufficiently negative voltage relative to the mercury, the junction resistance suddenly decreased by at least an order of magnitude, and high resistance could be restored by a positive voltage ...

– The conductance of cis/trans isomers of stilbene molecules connected to armchair single wall carbon nanotubes is studied in the Landauer formalism combined with a densityfunctional based approach. For a given arrangement of the electrodes, dramatic differences in the transmission between both isomers are found. For a given isomer, the conductance can be varied by orders of magnitude by changi...
