This article discusses recent experiences with the Numeral Unit Spread Assessment Pedigree (NUSAP) system for multidimensional uncertainty assessment, based on four case studies that vary in complexity. We show that the NUSAP method is applicable not only to relatively simple calculation schemes but also to complex models in a meaningful way and that NUSAP is useful to assess not only parameter...

I n the past, energy-aware computing was primarily associated with mobile and embedded computing platforms. Servers—high-end, multiprocessor systems running commercial workloads—typically included extensive cooling systems and resided in custom-built rooms for high-power delivery. In recent years, however, as transistor density and demand for computing resources have rapidly increased, even hig...

some servers are to be located at nodes of a network. demand for services of these servers is located at each node and a subset of the nodes is to be chosen to locate one server in each. each customer selects a server with a probability dependent on distance and a certain amount of benefit is achieved after giving service to the customer. customers may waive receiving service with a known proba...

There have been numerous attempts to decompose operating systems into multiple servers running on top of a microkernel. Decomposition offers a lot of advantages, such as better security and robustness, flexibility with respect to changing requirements, reusability of servers in different contexts, and maintainability due to clearly defined roles and interfaces. Yet, multi-server operating syste...
