In 1971, the first microprocessor produced in mass production had 2300 transistor and was able to compute 60'000 operations per second at 740 kHz. Nowadays, even a common gaming console uses a central unit including 243 millions of transistors running at 4 ...
In a distributed application, high-availability of a critical online service is ensured despite failures by duplicating the vital components of the server. Whilst guaranteeing the access to the server at all times, duplication requires particular care, so ...
Ada 9X refines the Ada 83 concept of class and introduces class-wide types to support run-time polymorphism. We study how the Ada definition of class compares to other definitions of this term. We examine how run-time polymorphism is introduced in Ada 9X, ...
This work is concerned with the global continuation for solutions (λ,u,ξ) ∈ R × C1{0}([0,∞), RN) × Rk of the following system of ordinary differential equations: where F: [0,∞) × RN × U × J → RN and φ: U × J → X1, for some open sets J ⊂ R and U ⊂ Rk, and w ...
We present three operators for the expression of event-based large-scale distributed programming. In short, these operators support a publish/subscribe-based interaction scheme, leading to a distributed object programming model merging the benefits of obje ...
A finite-temp. linear tetrahedron method for electronic structure calcns. of periodic systems is developed. When compared to widely used simple temp. broadening, the no. of k points necessary for accurate integration at finite temps. is reduced. The utilit ...
Large-scale distributed data management with P2P systems requires the existence of similarity operators for queries as we cannot assume that all users will agree on exactly the same schema and value representations and data quality problems due to spelling ...
This thesis, based on a project realised in cooperation with Électricité de France (EDF), proposes a new concept for a Decision Aid Function FOr Restoration (DAFFOR) of transmission power systems after a blackout. DAFFOR is an interactive computer tool whi ...
We describe a new fluorescence imaging device for clinical cancer photodetection in hollow organs in which the image contrast is derived from the fluorescence lifetime of the fluorochrome at each point in a 2D image. Lifetime images are created from a seri ...
