Abstract:In this paper, we consider the classical risk process perturbed by diffusion. The analysis is focused on the aggregate dividends and the Laplace transforms of ruin time. We showed that both the expected discounted dividends and the Laplace transforms of ruin time under a barrier strategy satisfy some integro-differential equation, and give the closed form expression of them, extending the results of Gerber and Shiu (2006). | |||

Abstract:Letting X_i=\sum\limits_{k=0}^{\infty}a_{k}\varepsilon_{i-k}, where {a_k} is a sequence of real numbers and {\varepsilon_{i}, -\infty<i<\infty} is a doubly infinite sequence of i.i.d. random variables, the multi-dimensional weak convergence of partial sum processes of {X_i, i\geq1} is studied. We consider the case of \theta=1 in Mielniczuk (1997) | |||

Abstract:Consider the decentralized estimation of an unknown parameter by bandwidth constrained sensor network with a fusion center. Local sensors make observations which are linearly scaled versions of these parameters corrupted by additive noise. For each sensor, the probability distribution functions of the noise is known. In this paper, we propose a new approach that convert the estimation fusion problem to decision fusion problem. With the methods of decision fusion, we find optimal local sensor compress rules which compress sensor observations into bits. The fusion center combines the transmitted bits from all the local sensors to generate a final estimator of the unknown parameter. Numerical examples show the efficiency of the new method. | |||

Abstract:To overcome some of the traditional material’s major disadvantages,a variety of composite bipolar plates have been developed. The compound structure bipolar plates consisting a metal core layer and a conductive polymer outer layer not only utilize the metal’s advantage , but also prevent the metal from being corroded. And the flow field can be easy obtained by injection moulding. The key problem of this kind bipolar plate is how to enhance the bond between two layers. The conductive polymer bipolar plate has the specific advantage, which is coated noble metal on, can increase the conductivity remarkably. The high polymer/ graphite composite bipolar plates are being improved in materials selection, formulation and preparation, the mechanical strength and the conductivity have been rised. The detail contents of some high conductivity bipolar plates are described in this paper. | |||

Abstract:In this research, a transient experimental system was designed to determine the thermal conductivity of the metals and alloys whose theoretical foundation was an axial periodic heat flow technique. Meanwhile, mathematic calculation was applied to intuitively simulate the heat transfer and temperature periodic change process,to correct the error and then to increase the result precision to some extent. In verification experiment, compared with the recommended data from reference, the error of the corrected experimental results is within ±5% at the temperature range of 300~800K which means the competitive method and the measuring system have the comparative reliability. The research on the method and the measuring system will pave the way to the subsequent research on the metals and new alloys such as lead-free eutectic solders. | |||

Abstract:This paper studies the efficiency of power system transient stability distributed simulation and the methods to enhance the computation performance. With parallel in space scheme, power system is split into several subsystems. The bottlenecks in distributed computation are the low speed network communication and the mass times of boundary values exchange for subsystem time domain step solution. For that the iterative boundary values convergence property is the key factor to affect the efficiency, three Boundary Values Methods(BVM) are presented to improve the subsystem solution convergence property. With the BVM, the necessary exchanging times of boundary values are reduced, the communication times for one time domain step is shorten and the distributed computation efficiency is improved. | |||

Abstract:he purpose of this paper is to experimentally investigate the engine pollutant emissions and combustion characteristics of a diesel engine fueled with ethanol-diesel blended fuel. The experiments were performed using various proportions of ethanol-diesel blended fuels in a single-cylinder DI diesel engine. The engine performance parameters and emissions were measured, and compared to those using the baseline diesel fuel. In order to gain insight into the combustion characteristics of ethanol-diesel blends, the engine combustion processes for blended fuels and diesel fuel were observed using an Engine Video System (AVL 513). The results show that the brake specific fuel consumption (BSFC) increased at overall engine operating conditions, but it is worth noting that the brake thermal efficiency (BTE) increased by up to 1~2.3% with 10% and 15% ethanol-diesel blended fuels. It is found that the engine fueled with ethanol-diesel blended fuels have higher emissions of THC, and lower | |||
