In this paper, we consider an optimal financing and dividend control problem of an insurance company. The management of the insurance company controls the dividends payout, equity issuance and the excess-of-loss reinsurance policy. In our model, the dividends are assumed to be paid out...

In this paper, heat transfer and air flow in a composite-wall solar-collector system with a porous absorber has been studied. The [`]unsteady' numerical simulation is conducted to analyze the performance of heat transfer and air flow in the composite wall. The excess heat is stored in the porous...

A diesel engine is modified for homogeneous charge compression ignition (HCCI) combustion with dimethyl ether. With and without knock, in-cylinder pressure is acquired, and in-cylinder temperature, rate of heat release (ROHR), pressure rise rate and pressure rise acceleration obtained. Wavelet...

This paper examines trades and trade relationships among China, Japan, and South Korea. It shows that China possesses a large comparative advantage in labor-intensive products, while Japan and Korea maintain large comparative advantages in capital-intensive products. Using quarterly data from...

The global economic crisis has attracted renewed attention to the issue of trade finance as exporters in some countries, particularly SMEs, struggle to secure much needed short-term financing and protection against rising commercial risks at a time when demand for their products has fallen...

Fossil energy subsidies reform would be an effective way to improve the energy consumption structure; however, the reform needs to be assessed comprehensively beforehand as it would exert uncertain impacts on economy, society and environment. In this paper, we use price-gap approach to estimate...

Human activities have become a major source of Earth’s climate change, which brings the rise of surface air temperature and subsurface ocean temperature. Therefore, promoting sustainable consumption and production patterns is imperative to minimize the use of natural resources and reduce...

This paper considers the estimation and the hypothesis testing on the equality of the ratios of the means to standard deviations of several normal populations with difference sample sizes. We propose an iterative algorithm to find the maximum likelihood estimates (MLEs) of the normal population...
