Due to the increasing demand for mobility in the area of distributed systems, the use of wireless communication gains in importance. We present a wireless real-time communication protocol for the interconnection of several possibly mobile fieldbus clusters. The protocol is based on the time-triggered paradigm. A single dedicated master node is used to keep the clocks of all slaves synchronized,...

This paper introduces the APHID (Asynchronous Parallel Hierarchical Iterative Deepening) game-tree search algorithm. An APHID search is controlled by a master and a series of slave processors. The master searches the rst d 0 ply of the game-tree repeatedly. The slaves are responsible for the bottom plies of the game-tree. The slaves asynchronously read work lists from the master and return scor...

We study informational asymmetry on the slave markets through notarial acts on public slave auctions in Mauritius between 1825 and 1835, involving 4,286 slaves. In addition to slave characteristics, the acts document the identities of buyers and se...
