Fretting fatigue process have many features such as early stage crack initiation at contact edge, very slow crack propagation and fatigue failure after very long life operation. In this paper at first we present fretting fatigue model in high cycle region, which is considering the wear process near contact edge. And then we present fretting fatigue life estimation method in low cycle fatigue re...

Why do firms choose different wage-setting practices and how do they affect firm dynamics over the business cycle? We introduce a novel theory for explaining the take-up of performance pay versus fixed wage contracting across industries. Firms with lower adjustment costs face a greater option value associated with investment before observing actual product demand, whereas firms with higher adju...

We find that survey evidence on faculty pay-cycle choice strongly contradicts the neoclassical theory of consumer behavior. It is more favorable to the behavioral life-cycle theory of Shefrin and Thaler (1988). JEL: D12

Firms are key drivers of urban growth along with households, yet data on businesses and commercial vehicle movements can be quite difficult to obtain. An understanding of firm behavior over time is critical in anticipating urban futures and addressing transportation, land use and other concerns. Firm birth and death, migration and location choice are defining events in a firm’s life cycle, and ...

Manufacturers are moving more and more towards the business approach of Product/Service Systems (PSS) in order to achieve greater revenue. PSS have many benefits such as achieving closer customer connection and generating increased profit from manufactured products. However, in order to achieve a PSS which is adapted for this business approach, the products and services used need to consider a ...
