With the advance of photovoltaic panel technology, infrastructure equipment cellular networks with solar energy sources has attracted extensive interests. It is expected that base stations (BSs) and relay (RSs) renewable will play important roles in reducing power consumption from electrical grids future green networks. Inspired by this technology trend, paper considers a heterogeneous network, which part RSs powered to represent incremental deployment for near future. We formulate new...
In this article, an injected type-adaptive impedance (IT-AI) inverter is proposed for low capacity requirement and wide reactive power compensation range. Different fromthe traditional coupling impedance, the IT-AI not only used to reduce voltage stress of but also current stress. Moreover, adaptive in injection circuit can expand range without additional harmonics. However, there a risk fundamental frequency resonance between IT-AI. To overcome challenge, phenomenon analyzed through...
Nematic liquid crystal cells which have a narrow width nearly the same as thickness were found to exhibit self-sustained angle-deflective oscillation of stripe pattern above threshold applied voltage V th . The amplitude was be proportional ( 2 - ) 1/2 range where occurs corresponds fluctuating Williams domain is observed for rectangular cell with wide width.
Cholangiocarcinoma (CCA) is a highly malignant cancer, characterized by frequent mucin overexpression.
Abstract An improved model predictive control (MPC) with Luenberger state observer is proposed in this article for LC‐coupling hybrid active power filter (LC‐HAPF). Traditionally, the implementation of MPC LC‐HAPF requires additional sensors to measure coupling capacitor voltage, thereby increases system cost and reduces reliability. The existence one‐step sampling delay practice will also affect final compensation performance. To relax these problems, both continuous discrete models are...
Abstract The underwater acoustic transducer (UAT) generates a large amount of reactive power during the operation, greatly limiting output capability amplifier. It is necessary to match UAT and improve its load characteristics. conventional design methods are not powerful enough solve nonlinear or parameter‐sensitive problems, lacking convergence ability for network problem. This article proposes an optimization method LCCLC impedance matching based on improved chaos algorithm corresponding...
An improved model predictive control (MPC) with Luenberger state observer is proposed in this article for LC-coupling hybrid active power filter (LC-HAPF). Generally, the implementation of MPC LC-HAPF requires additional sensors measuring coupling capacitor voltage, which increases system cost and reduces reliability. To relax these problems, both continuous discrete models are deduced first. Then, utilized based on to mitigate steady-state error without sensors. In addition, delay...
Abstract The elliptic cavity tube absorber is used in the parabolic trough solar collectors to increase optical efficiency and decrease thermal loss. But non-uniform heat flux distribution on receiver will cause temperature distribution, thus leading asymmetric stress deformation of receiver. In this paper, geometric as well parameters elliptical are analysed through numerical simulation. single-phase liquid zone, viz. water zone vapour analysed. It found from study that there two extreme...
An evolution process has been investigated for the angle-deflective oscillation of stripe pattern by changing suddenly an applied voltage across a thin layer nematic liquid crystal from sub-threshold to above-threshold voltage. averaged time course amplitude and its fluctuation have obtained data processes repeated Anomalies in found intermediate stage process.

The shows another behavior different from OSI.
