loop...
We extend previous results for optimally scheduling
concurrent program modules, called tasks, on a fixed, finite number
of parallel processors in two fundamental ways: (1) we introduce a
new heuristic which considers the time delay imposed by message
transmission among concurrently running tasks; and (2) we
introduce a second heuristic...
The goal of this thesis is to advance the methodology and thought regarding the transferability of ecological estimates of ecosystem services. Conceptually and in practice, ecological estimate transfer parallels economic benefit transfer in ecosystem services research and policy, yet the literature for benefit transfer predates ecological estimate transfer by several...
Very High Level Languages (VHLL) provide higher level abstractions and more powerful primitives than high level languages (HLL). A programmer uses these abstractions to solve a problem by specifying "what" is to be done rather than "how" it is to be done. This research work reports the design and development...
First, we study hard real-time scheduling problems where each task is defined by a four tuple (r, c, p, d): r being its release time, c computation time, p period, and d deadline. The question is whether all tasks can meet their deadlines on one processor. If not, how many...
The methodology of structured programming has
enabled rapid progress in many areas of theoretical
computer science. Structured programs are generally
easier to debug, test, prove and analyse. The development
of these achievements into commercially viable applications
and products has been slower than expected.
The primary reason is that most of...
