The self-powered system is a promising concept for wireless networks due to its independent and sustainable operations without an external power source. To realize this idea, the triboelectric nanogenerator (TENG) was recently invented, which can effectively convert ambient mechanical energy into electricity to power up portable electronics. In this work, a self-powered smart window system was ...

in this paper, reconfiguration problem of distribution network has been investigated toimprove reliability and reduce power loss by placement of renewable energy sources; i.e. solarcell and wind turbine. for this, four reliability indices are considered in objective function;which are as follows: system average interruption frequency index (saifi), system averageinterruption duration index (sai...

PURPOSE In a coupled parallel transmit (pTx) array, the power delivered to a channel is partially distributed to other channels because of coupling. This power is dissipated in circulators resulting in a significant reduction in power efficiency. In this study, a technique for designing robust decoupling matrices interfaced between the RF amplifiers and the coils is proposed. The decoupling mat...

The present work addresses the identification of third-order Volterra models from input-output process data. Building on previous studies regarding input sequence design for third-order Volterra models (Soni and Parker, 2004), a new reduced-length sequence is designed to identify third-order sub-diagonal kernels. This input sequence leads to a 30% reduction in the data required to accurately es...

optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

Frequency-domain model reduction is a crucial concern in applying the prevailing impedance method for stability analysis of complex systems, e.g., modular multilevel converter (MMC). Recently, it has been shown that under symmetric conditions, 2 × matrix-based characterizing two coupled frequencies MMC are sufficient its analysis. However, when asymmetry occurs, principally, much higher number ...

Triggered by a controversy surrounding universal behavior of the power spectrum in quantum systems exhibiting regular classical dynamics, we focus on model random diagonal matrices (RDM), often associated with Poisson spectral universality class, and examine how form factor get affected two-sided truncations RDM spectra. Having developed nonperturbative description both statistics, perform thei...

distributed generations (dgs) are utilized to supply the active and reactive power in the transmission and distribution systems. these types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. in order to reach the above benefits, the optimal placement and sizing of dg is...

Existing block-diagonal representation studies mainly focuses on casting block-diagonal regularization on training data, while only little attention is dedicated to concurrently learning both block-diagonal representations of training and test data. In this paper, we propose a discriminative block-diagonal low-rank representation (BDLRR) method for recognition. In particular, the elaborate BDLR...
