In this study, the authors reported an influence of activated carbon fibres (ACFs) with different specific surface areas on the thermal conductive and electrical insulating properties of polymeric composites. Here, the polyamide-imide composites were obtained via solution blending and cured method. The composites exhibited thermal conductivity (TC) up to 0.62 W·m−1·K−1. In addition, the composites...
The problem of output regulation by means of partial state and parameters information for the DC-DC converter is addressed. It is shown that the combination of a output feedback controller with the H∞ performance yields a globally asymptotically stable closed-loop system. Finally, the simulation results show the effectiveness of the proposed method.
Non-rigid organ misregistration is an important problem for patients undergoing sequential quantitative SPECT for 3D dosimetry for targeted radionuclide therapy (TRT) treatment planning. This study aims to evaluate effects of these misregistrations on the accuracy of 3D dosimetry. We used 3 anatomical variations and 3 respective In-111 Zevalin distributions of the digital 4D Extended Cardiac Torso...
We discuss an optimal asset allocation problem in a wide class of discrete-time regime-switching models including the hidden Markovian regime-switching (HMRS) model, the interactive hidden Markovian regime-switching (IHMRS) model and the self-exciting threshold autoregressive (SETAR) model. In the optimal asset allocation problem, the object of the investor is to select an optimal portfolio strategy...
We consider an optimal selection problem for bid and ask quotes subject to a value-at-Risk (VaR) constraint when arrivals of the buy and sell orders are governed by a Poisson process. The problem is formulated as a constrained utility maximization problem over a finite time horizon. Using a diffusion approximation to Poisson arrivals of market orders, the dynamic programming principle can be applied...
In recent years, enterprises are increasingly paying more attention to knowledge management. Based on the theory of service value chain, the paper gains sufficient insights into the knowledge management process of enterprises in order to construct a model of the knowledge management of enterprises, thus identifying the critical factors which influence the improvement of performance. A knowledge management...
This paper proposes the method that makes an input target image into exaggerated cartoon-like images by using reference images. To deform a target image, we extract feature points from a target image and define the feature point model on reference images. And then, we apply feature based warping method to this deformation. For our result be felt more cartoonish, we additionally apply the luminance...
In this paper, we develop an option valuation model in the context of a discrete-time multivariate Markov chain model using the Esscher transform. The multivariate Markov chain provides a flexible way to incorporate the dependency of the underlying asset price processes and price multi-state options written on several dependent underlying assets. In our model, the price of an individual asset can...
At present the service science and engineering research are mainly focus on service discovery, service composition, service reputation and other key technical of the service computing. However the basic theory of service science, in particular, the basic principle of service and the evolution mechanism of service network only have some preliminary of research and exploration. The atomic services as...
After defining the concept of creative industry cluster and citing the industrial cluster mechanism of the outside source, and drawing on the successful experiences of the domestic and foreign governments in the creative industries cluster development, we focus on the role of the government in the creative industry cluster and put forward of the feasible suggestions.
In this paper, we propose an based on KHA for extraction of shift invariant multiwavelet features of texture images. The feature extraction process involves a normalization followed by a shift invariant multiwavelet packet transform. The normalization converts a given image into a size invariant image which is then passed to the shift invariant multiwavelet packet transform to generate subbands of...
OFDM system can improve frequency band utility, decrease symbols interference caused by multi-path effect. It also can obtain reliable data transmission with high speed. The paper studies the channel estimation technique in a digital radio broadcast receiver based on OFDM-DRM. Due to the time and frequency selective variance of the channel encountered during OFDM transmission, the channel response...
ATP has become widely recognized as a key mediator in both central and peripheral chemosensory transduction in adult rat. The distribution of P2X receptor subtype and the role of ATP in neonatal rat are unclear. The main objective of this study was to observe the role of ATP-mediated respiratory activity in the neonatal rat transverse medullary slice. The increase of respiratory activity was dose-dependent...
