Tribological and dry drilling performance of WS2/Cr-AlCrN coatings
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2021 Dry drilling gives a higher request to the anti-friction property of cutting tools. However, most tool coatings commonly have less lubricant effect. In present paper, WS2/Cr layer was deposited on AlCrN layer by a radio frequency magnetron sputtering ...

Theory of the Firm: Applied Mechanism Design [PDF]
SSRN Electronic Journal, 1996 This paper studies the question: Why are there Firms? Motivated by observations of a variety of economies, several distinct concepts of what it means to be a firm are identified and then analyzed with mechanism design models. In the first class of models, a group of individuals is a firm if they collude and share information. This model is analyzed and

Designing Random Allocation Mechanisms: Theory and Applications [PDF]
American Economic Review, 2013 Randomization is commonplace in everyday resource allocation. We generalize the theory of randomized assignment to accommodate multi-unit allocations and various real-world constraints, such as group-specific quotas (“controlled choice”) in school choice and house allocation, and scheduling and curriculum constraints in course allocation.
