In the design of supersonic low-boom aircraft, it is important to balance the aerodynamic performance and sonic boom requirements in a way that represents the best compromise for the overall design. Since the ground sonic boom is typically not a smooth function of the design variables and may actually contain multiple local minima, it is important to select an optimization algorithm that is abl...

According to the existing problems in the development of actual product and working process of excavator working device’s boom, the method of integrated design and analysis for excavator boom is put forward. The defects in the process of CAD/CAE integration are summarized, the integrated design and analysis system including parametric design of boom, database design, detail feature simplificati...

The paper provides a theoretical explanation of the common claim that larger buyers pay lower prices. In the model, suppliers compete more aggressively for the business of larger buyers, much as they do in “boom” periods in Rotemberg and Saloner (1986).

E-CIM – Tautologie oder Herausforderung? Zur Beantwortung dieser Frage befaßt sich der Autor kritisch mit der unternehmensübergreifenden Kooperation autonomer Organisationseinheiten. Entgegen der in der Vergangenheit oftmals euphorischen Betrachtung virtueller Organisationen beschreibt das vorliegende Buch ein praxisorientiertes Konzept, das den Leser auffordert, sich in der Zeit nach dem E-Bus...

Physicians upset by limits imposed by the medicare system are getting a chance to spread their entrepreneurial wings on the East Coast. A boom in offshore exploration, led by Newfoundland's massive Hibernia project, has led to numerous business opportunities for physicians.

Background: In order to achieve development, there is a need to pay attention to corruption, violence and poverty of nations, which stems from the lack of economic ethics and business environment ethics. Fundamental elimination of corruption, violence and poverty of nations in line with the practical motivations of economic development will not be possible except with the growing link between e...

The application of Internet technologies for the conduct of interfirm business transactions has given rise to a boom in business-to-business (B2B) electronic commerce. Yet, although there are many success stories that have been reported over the past several years, the progress of B2B e-commerce has been hindered by unanticipated technical, organizational, economic and legal challenges that dim...

During the 1990s, market hours in the United States rose dramatically. The rise in hours occurred as gross domestic product (GDP) per hour was declining relative to its historical trend, an occurrence that makes this boom unique, at least for the postwar U.S. economy. We find that expensed plus sweat investment was large during this period and critical for understanding the movements in hours a...
