We consider an energy harvesting wireless communication link, where arriving data packets have different importance values. The wireless transmitter needs to decide whether each arriving data packet should be transmitted or not, based on the packet's importance value, channel condition, and energy status. Under certain conditions, we show this high dimensional control problem can be transformed to...
This paper presents coupling characteristics of multiple traps in HKMG nMOSFETs by a 3D kinetic Monte-Carlo (KMC) simulator we developed, which includes several fully-coupled multi-physical models: trap generation/recombination, trapping/detrapping to/from channel, metal gate, and the interaction of traps. It shows that activation energy and trapping/detrapping from/to channel/gate impact on coupling...
Besides the evident superiority, the Geosynchronous Earth orbit synthetic aperture radar (Geo-SAR) system meets great more challenges than the current Low-Earth-Orbital SAR (Leo-SAR) and the Medium-Earth-Orbit SAR (Meo-SAR). The signal processing approach for spotlight mode Geo-SAR is discussed in this paper. A new range model called the sixth-order Doppler parameter range model (DRM-6) is derived...
Peer-to-Peer (P2P) systems have brought two serious problems for Internet Services Providers (ISPs): traffic surges and network congestion. Proxy caching for P2P traffic is an effective means of easing the burden imposed by P2P traffic on ISPs. The deployment strategy of proxy caches has a significant impact on their effect on ISPs. It has two important components: one is cache operation that is what...
CPW based multilayer inductors which can provide higher frequency band and Q factor value are studied and characterized so that a new microwave Equivalent circuit model may be found. In order to study the correlation between the inductance and the length, width and thickness of the conductor, EM structures of multilayer inductors are designed and compared of electrical models. Data analysis and graphic...
Composite fading (i.e., multipath fading and shadowing together) has increasingly been analyzed by means of the K channel and related models. Nevertheless, these models do have computational and analytical difficulties. Motivated by this context, we propose a mixture gamma (MG) distribution for the signal-to-noise ratio (SNR) of wireless channels. Not only is it a more accurate model for composite...
The construction of Smart Grid will comprehensively enhance the intelligent level of every step in the power grid of our country. The data forecasting ability determines the quality of smart grid. As a result of this, this paper constructs the background value of grey GM (1, 1) model by using threepoint Gaussian quadrature formula, improves its accuracy and the data quality. It indicates that reconstruction...
A novel annular spouted bed with multiple gas nozzles, has been proposed for dryness, pyrolysis, and gasification of coal particulates. It consists of two homocentric upright cylinders with some annularly located spouting gas nozzles between inner and outer cylinders. A three-dimensional Eulerian multiphase model, with closure law according to the kinetic theory of granular flow, was used to simulate...
