Copy right Idea Grou p Inc . Copy right Idea Grou p Inc . Internet online sales totaled $7.8 billion for 1998, with the average online shopper spending $629 (Fasig, 1999). During the 1999 holiday season, online sales were reportedly double that of 1998 at many “e-tailers” (although final statistics had not been published as this chapter went to press). As Web-based consumer sales grow, so does ...

T HE industrial sector has long been regarded as the stepchild of marketing in terms of the amount of research effort devoted to its problems. There are, however, indications that the situation may be changing. Research on industriallorganizational buying behavior is growing, and a considerable body of empirical knowledge about processes surrounding the innovation and diffusion of industrial te...

The distribution of quality characteristic of a product is usually assumed to be known. In some situation, the quality characteristic of a product cannot be measured directly. It needs to be measured by controlling another factor. Wen and Mergen (1999) presented a method for determining the optimum process mean in order to minimize the expected total loss of a product. However, they have not co...

The loss caused by the so-called minor diseases is not usually considered of sufficient importance to warrant the adoption of control measures such as those used in combating major diseases; nevertheless it has frequently been asserted that if the total loss due to the activities of all minor diseases could be estimated it would probably amount to more than is imagined. Further, a disease which...

"What about the gym?" was the big question at this week's presidential press conference, as all other school matters were put aside. The crowd filed from the Patroon lounge to the Assembly Hall and finally to the Ballroom. The number of persons attending seemed to increase with every move and soon totaled 600 or 700. Dr. Clifton Thome, VicePresident of Student Affairs, held the press conference...

Analyzing the nonlinear vibration of beams is one of the important issues in structural engineering. According to this, an impressive analytical method which is called Modified Iteration Perturbation Method (MIPM) is used to obtain the behavior and frequency of a cantilever beam with geometric nonlinear. This new method is combined by the Mickens and Iteration methods. Moreover, this method don...

Using a combination of resist reflow to form a highly circular etch mask pattern and a low-damage plasma dry etch, high-quality-factor silicon optical microdisk resonators are fabricated out of silicon-on-insulator (SOI) wafers. Quality factors as high as Q = 5x10(6) are measured in these microresonators, corresponding to a propagation loss coefficient as small as alpha ~ 0.1 dB/cm. The differe...

Heat losses from a trough cavity receiver were investigated in order to eventually optimise the reactor geometry for ammonia-based solar energy storage with troughs, which are prominent in the SEGs plants of California. To this end, experiments were performed with a small-scale receiver containing heating elements. This gave free convection loss coefficient values from 0.3 to 11.8 W/(m.C) from ...

This study proposes the concept of the local heat loss coefficient and examines the calculation method for the average heat loss coefficient and the average absorber plate temperature. It also presents an exergy analysis model of flat plate collectors, considering non-uniformity in temperature distribution along the absorber plate. The computation results agree well with experimental data. The ...
