Even though the roots of the global financial crisis lay in risky financial structures in the United States and weaknesses in financial regulation, the crisis became global mainly because of significant financial and trade linkages between the US and other countries. Most countries, including...

The purpose of this study is to investigate the effects of various engine conditions on the combustion, flame temperature and emission characteristics of dimethyl ether (DME) fuel compared with ultra-low sulfur diesel (ULSD) fuel through experimental and numerical analyzes. In order to analyze...

In this paper, effect of varying fuel injection pressures and injection timings on particulate size number distribution and spray characteristics was investigated in a single cylinder, common rail direct injection (CRDI) compression ignition (CI) engine fueled with Karanja biodiesel blends...

In the present study, the combustion and emission characteristics under various equivalence ratio up to stoichiometric condition were experimentally investigated in a CI (compression ignition) engine. In order to control the equivalence ratio, the O2 mole fraction of intake gas was reduced from...

The aim of this study was to confirm the effects of two-stage combustion on the combustion and NO<em>_x</em> reduction characteristics of a four cylinder direct injection diesel engine. In order to analyze the combustion and emission characteristics, various injection parameters, such as injection...

The present paper suggests fuel consumption modeling for HDVs based on the code from the Japanese Ministry of the Environment. Two interpolation models (inversed distance weighted (IDW) and Hermite) and three types of fuel efficiency maps (coarse, medium, and dense) were adopted to determine the...

Engel (1999) computes the variance of k-differences for each time horizon us- ing the method of Cochrane (1988) in order to measure the importance of the traded goods component in U.S. real exchange rate movements. The importance of traded goods should decrease as the horizon increases if the...

Since 1995, four presidents have granted six traffic violation pardons in Korea, and 24.6 million individuals have been the beneficiaries of these pardons. The objective of this paper is to explore how costly traffic violation pardons are by finding out the effects of traffic violation pardons...

This paper argues that "Do auctions raise consumer prices?" is a misleading question. License fee payment methods, rather than spectrum assignment methods, are key factors that bring forth different market outcomes in the wireless telecommunication industry. This paper analyzes and discusses the...

This paper proposes a new estimation method of total cost and average cost curves and applies it to the telecommunications industry. The method is more flexible and entails less hassle for data collection than traditional methods. The results show that the long-run average cost (LRAC) curve is...
