In order to study factors affecting lean combustion limit, an experimental study was carried out on a spark- ignited engine fueled with compressed natural gas and hydrogen blends. Effects of ignition timing, hydrogen fraction, engine speed, throttle opening, coolant and oil temperature were...

In order to investigate the effects of altitude on the brake thermal efficiency of heavy-duty diesel engines, an experimental study on a heavy-duty diesel engine operating at various altitudes was conducted. Tests were conducted in low and moderate load and speed conditions. Brake thermal...

Exhaust particle numbers from a light-duty vehicle diesel engine for transient-state operating conditions were studied. The test fuels were petroleum diesel, pure Jatropha biodiesel (B100), 20% and 50% biodiesel blends with diesel fuel (B20 and B50). The results show that the number of...

A fundamental marketing problem faced by auctioneers is the promotion of their auction in order to recruit bidders. Merchants would like to attract as many bidders as possible to an auction, since the higher the number of bidders, the higher the expected winning price and profitability. This...

Recently fixed pricing and auctions have been brought together in a new pricing format that offers bidders the option of prematurely ending an auction at a fixed price. eBay calls this a “Buy-it- Now” auction, uBid calls this “UBuy it” and Yahoo auctions refer to this as a “Buy Now”....

The general theme of my dissertation research is channel management and the related pricing issues. My research aims to contribute to the extant marketing literature by providing both theories and empirical analyses regarding the emerging channels of distribution, namely, the various electronic...

We re-examine prior studies' findings concerning the effects of Regulation Fair Disclosure (Reg FD) on properties of US firms' information environments. Our study's innovation is the identification of a sample of industry- and size-matched foreign listed firms (ADRs) explicitly exempt from the...

We re-examine the effects of regulation fair disclosure (Reg FD) using ADRs (who are exempt from Reg FD) to control for confounding events which affected all traded firms. Tests based on public information metrics (returns volatility, informational efficiency and trading volume) and on analyst...

<title>Abstract</title>In order to eliminate the impact of the sample's objective merits on the evaluation results, this research built a two-stage model of Chinese airline competitiveness evaluation to reflect the subjective management and performance. In the first stage, Analytic Hierarchy Process (AHP) and...
