We investigate here the computational complexity of three natural problems in directed acyclic graphs. We prove their NP Completeness and consider their restrictions to linear orde...
We have implemented a set of computational physics codes on a network of IBM RS/6000 workstations used as a distributed parallel computer. We compare the performance of the codes ...
Displaying and navigating complex information on wearable computers is very different from accessing the same information while sitting at your desk. Limitations in hardware, scre...
