The Vehicle Routing Problem with Time Windows consists of computing a minimum cost set of routes for a fleet of vehicles of limited capacity visiting a given set of customers with known demand, with the additional constraint that each customer must be visi ...
Device drivers today lack two important properties: guaranteed safety and cross-platform portability. We present an approach to incrementally achieving these properties in drivers, without requiring any changes in the drivers or operating system kernels. W ...
Profilers based on hardware performance counters are indispensable for performance debugging of complex software systems. All modern processors feature hardware performance counters, but current virtual machine monitors (VMMs) do not properly expose them t ...
Developers rely on automated testing and verification tools to gain confidence in their software. The input to such tools is often generated by compilers that have been designed to generate code that runs fast, not code that can be verified easily and quic ...
Linear time-invariant (LTI) modeling is a powerful and simple tool to describe biomedical systems dynamics around given working points for a limited time horizon. However, when a larger range of behaviors is considered, and/or the time horizon becomes wide ...
The following dissertation addresses one aspect of cooperative editing which has not been well examined until now : the consideration of hardware limitations imposed by a large scale distributed system (namely the Internet). This system model implies heter ...
A new highly optimized application, the Real-time Visible Human Navigator, provides the possibility to extract arbitrarily oriented and positioned slices from the Visible Human dataset in real-time on a standard PC. A continuous sequence of slices is displ ...
This paper presents Vassal, a system that enables applications to dynamically load and unload CPU scheduling policies into the operating system kernel, allowing multiple policies to be in effect simultaneously. With Vassal, applications can utilize schedul ...
A multiprocessor multiwindow parallel visualization subsystem is presented which can be hooked onto parallel processor arrays of high-speed network interfaces. Thanks to its well-balanced triple transputer architecture, the multiwindow display subsystem is ...
