Janus within Janus

We found a simple and interesting generalization of the non-supersymmetric Janus solution in type IIB string theory. The Janus solution can be thought of as a thick AdSd-sliced domain wall in AdSd+1 space. It turns out that the AdSd-sliced domain wall can support its own AdSd−1-sliced domain wall within it. Indeed this pattern persists further until it reaches the AdS2-slice of the domain wall ...

QD-Janus: a Sequential Implementation of Janus in Prolog

Janus is a language designed for distributed constraint programming. This paper describes QDJanus, a sequential implementation of Janus in Prolog. The compiler uses a number of novel analyses and optimizations to improve the performance of the system. The choice of Prolog as the target language for a compiler, although unusual, is motivated by the following: (i) the semantic gap between Janus a...

variable following an identical probability distribution as the arrival process. A new estimation method of the average travel time uses a crosscorrelation analysis of traffic flow measurement data. This method requires only traffic flow information, which is available from the measurements of single loop detectors upstream and downstream from one link. Different from the existing maximum cross...
