In this paper, the performance of a CNT-JLTFET under different values of torsional strains of 0, 3, and 5 degrees has been investigated. Simulation has been carried out using non-equilibrium Green’s function (NEGF) formalism in the mode-space approach and in the ballistic limit. The simulation results indicate that, under torsional strain, an increase occurs in the energy band-gap, and thus the...

due to the high efficiency and low switching losses of resonant power convertors in comparison with switching convertors, nowadays there is a growing trend towards these convertors. however, because of the high frequency of switching in such convertors, it is quite difficult to present an efficient control method. in this paper, based on the state feedback method and using pole placement techni...

Many biological systems can switch between two distinct states. Once switched, the system remains stable for a period of time and may switch back to its original state. A gene network with bistability is usually required for the switching and stochastic effect in the gene expression may induce such switching. A typical bistable system allows one-directional switching, in which the switch from t...

We propose a novel optical switching system equipped with shared wavelength converters with electrical buffers. Simulation results show that the proposed system significantly reduces the blocking probability below 10−6 with low buffering delay. We present benefits of the proposed switching system compared with the conventional dedicated wavelength converter scheme in terms of blocking probabili...

The burst aggregation strategy in Optical Burst Switching systems is a balancing act between delay to assemble the burst and efficiency in filling it. The longer the assembly time, the better the fill level. Slotted systems can simplify control and avoid very short and inefficient bursts but the slot assembly strategy becomes a critical issue particularly when service quality must be supported ...

In this paper we consider some stabilization problems for the wave equation with switching time-delay. We prove exponential stability results for appropriate damping coefficients. The proof of the main results is based on D’Alembert formula, observability inequality and some energy estimates. More general problems, like the Petrovsky system, are also discussed.
