This paper contributes to the study of tacit collusion by analyzing infinitely repeated multiunit uniform price auctions in a symmetric oligopoly with capacity constrained firms. Under both the Market Clearing and Maximum Accepted Price rules of determining the uniform price, we show that when each firm sets a price-quantity pair specifying the firm’s minimum acceptable price and the maximum qu...

It is well known that queues with exponentially distributed service time have the smallest Shannon capacity among all single-server queues with the same service rate. However, the capacity of other service disiplines such as Gaussian service timing channels (GSTC) remains unknown. In this paper, we outline a preliminary investigation into timing channel capacity, when the service distributions ...

additional members of the examination board. I would like to thank my " co-advisor " Berthold Vöcking for a very valuable collaboration. It was a lot of fun to master several problems in theoretical computer science and other major spheres of life with Berthold, such as solving a traveling salesperson problem given by the touristic highlights in California and changing several car tires with un...

the existence of some geometrically imperfect members, like initial curvature in a double layer space structures with hundreds or thousands of members is almost inevitable. these imperfections give rise to loss of load bearing capacity of double layer space structures. to evaluate the effect of initial member imperfection on load bearing capacity of double layer space structures and their failu...

This paper reports on investigations into capacity of a Multiple Input Multiple Output (MIMO) wireless communication system employing a uniform linear array (ULA) at the transmitter and either a uniform linear array (ULA) or a uniform circular array (UCA) antenna at the receiver. The transmitter is assumed to be surrounded by scattering objects while the receiver is postulated to be free from s...
