We study auctions under restricted communication. Bidders have valuations in a compact interval, but can only report one of a …nite number of messages. We provide a characterization of welfare as well as revenue maximizing auctions in the symmetric independent private values case when bidders report simultaneously. We show that the seller choosing how to allocate the …xed communication capacity...

A deterministic computing system is reversible if every configuration of the system has just one previous configuration or it is an initial configuration. In this paper it is proved that for every reversible register machine there exists a reversible P system with symport/antiport rules such that the P system accepts the same set of integers as the register machine accepts. The result shows tha...

Solar panels have been improving in efficiency and dropping in price, and are therefore becoming more common and economically viable. However, the performance of solar panels depends not only on the weather, but also on other external factors such as shadow, dirt, dust, etc. In this paper, we describe a simple and practical data-driven method for classifying anomalies in the power output of sol...
