AN ANALYSIS ON POTENTIAL ECONOMIC IMPACTS OF GREENHOUSE GAS MITIGATION THROUGH PLANTING ENERGY CROPS IN TAIWAN
The purpose of this study is to evaluate the economic and environmental impacts of planting energy crop on set-aside acreages in Taiwan. To do so, a Taiwan Agricultural Sector Model (TASM) was built and the data parameters of energy crop were incorporated into this model in order to simulate the economic and environmental impacts. Simulation results show that GHGE mitigation depends on the planting acreage of energy crops in which the optimal planting acreage of energy is determined by the profit of other agricultural products as well as government subsidy on energy crop. Therefore, the mitigation of GHGE depends on the government subsidy on energy crop per hectare. Such subsidy is also suitable for the green box by the regulation of WTO.Resource /Energy Economics and Policy,
Initial Public Offering and Corporate Governance in China's Transitional Economy
This paper empirically investigates the performance of Chinese initial public offerings (IPOs). The data used covers the period from mid-1995 to mid-1999 with the sample including 884 companies (both in the A- and B-share markets). In an examination of growth, profitability and stability of listed companies either individually or as a combination, it can be seen that the only industries in which listed companies in China display strong performance are public utilities, transportation and finance. If one examines the changes in listed companies' financial indicators following the IPO, it becomes apparent that with the exception of earnings related indicators (EPS and ROE) there are no significant changes. What's more, the financial indicators tend to fall rapidly year on year. This means that the IPO is of little obvious help to companies' operational performance, and may actually make things worse. One of the reasons for this is that in order to implement the IPO and secure stock market listing, companies tend to submit inflated figures in the financial statements that they are required to provide. Another possible factor is the poor corporate governance characteristics of Chinese enterprises.

Smoothed Boundary Method for Solving Partial Differential Equations with General Boundary Conditions on Complex Boundaries
In this article, we describe an approach for solving partial differential
equations with general boundary conditions imposed on arbitrarily shaped
boundaries. A function that has a prescribed value on the domain in which a
differential equation is valid and smoothly but rapidly varying values on the
boundary where boundary conditions are imposed is used to modify the original
differential equations. The mathematical derivations are straight forward, and
generically applicable to a wide variety of partial differential equations. To
demonstrate the general applicability of the approach, we provide four
examples: (1) the diffusion equation with both Neumann and Dirichlet boundary
conditions, (2) the diffusion equation with surface diffusion, (3) the
mechanical equilibrium equation, and (4) the equation for phase transformation
with additional boundaries. The solutions for a few of these cases are
validated against corresponding analytical and semi-analytical solutions. The
potential of the approach is demonstrated with five applications:
surface-reaction diffusion kinetics with a complex geometry,
Kirkendall-effect-induced deformation, thermal stress in a complex geometry,
phase transformations affected by substrate surfaces, and a self-propelling
droplet.Comment: A better smooth algorithm has been developed and tested, will soon
replace Eq. 58 in page 16. We have also developed a level-set moving boundary
SBM method, and it will replace the Navier-Stokes-Cahn-Hilliard type domain
parameter tracking method in Section 5.
A turbulence model for iced airfoils and its validation
A turbulence model based on the extension of the algebraic eddy viscosity formulation of Cebeci and Smith developed for two dimensional flows over smooth and rough surfaces is described for iced airfoils and validated for computed ice shapes obtained for a range of total temperatures varying from 28 to -15 F. The validation is made with an interactive boundary layer method which uses a panel method to compute the inviscid flow and an inverse finite difference boundary layer method to compute the viscous flow. The interaction between inviscid and viscous flows is established by the use of the Hilbert integral. The calculated drag coefficients compare well with recent experimental data taken at the NASA-Lewis Icing Research Tunnel (IRT) and show that, in general, the drag increase due to ice accretion can be predicted well and efficiently
MINIATURE MASS SPECTROMETER SYSTEM WITH A SAMPLING PROBE
This thesis focuses on the development of miniature mass spectrometry systems and the sampling probes. Mass spectrometers are usually installed and used in the analytical laboratory. It requires complex sample preparation before the analysis. Use of miniature mass spectrometer enables the chemical analysis outside the lab and a sampling probe provides convenience for real-time analysis. Two miniature mass spectrometer systems have been developed in this work
