Vegetables oils are simplest route of biofuel utilization in direct injection compression ignition (DICI) engines however several operational and durability problems are encountered while using straight vegetable oils in CI engines due to their high viscosity and low volatility. Reduction of...

Amongst primary alcohols, butanol is considered as the most promising alternative fuel candidate because of its favourable chemical and physical properties, which are quite similar to gasoline. Butanol is completely miscible with gasoline in any proportion and forms a stable blend. It is not...

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...

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 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 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...

Over-the-top media firms such as Netflix, Amazon Prime, and Hulu are transforming the coopetition relationship among media firms in the broadcasting market and the structure of the broadcasting industry. New entrants like OTT media firms kept using various coopetition strategies including...

Various types of broadcasters have been created due to the progress of broadcasting technology, and recently, global OTT services have threatened the raison d'être of PSBs. PSB opponents, based on neo-classical economics, argue that the government's support for PSB hurts fair competition and...

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...
