The use of control-based methods for resource management in real-time computing and communication systems has gained a substantial interest recently. Applications areas include performance control of web-servers, dynamic resource management in embedded systems, traffic control in communication networks, transaction management in database servers, error control in software systems, and autonomic co

A tool for synthesis of control units in application-specific digital signal processors is presented. Synthesis of a control unit is based on micro instructions generated for each processor module and includes no use of predefined functional blocks. Complexity and partitioning of the controller are dependent on the structure of the micro program. The control unit synthesizer has been developed for

In the context of the emerging bioeconomy, the production and use of biofuels for transport is expanding rapidly around the world. This development presents both exciting opportunities and significant risks. Not least because biofuels are intimately connected to (and impacting on) food, water, climate and economic systems. The implications of different production chains and the international trade

Decision trees constructed by ID3-like algorithms suffer from an inability of detecting instances of categories not present in the set of training examples, i.e., they are discriminative representations. Instead, such instances are assigned to one of the classes actually present in the training set, resulting in undesired misclassifications. Two methods of reducing this problem by learning charact

The key adaptive techniques are automatic tuning, gain scheduling and continuous adaptation. This paper describes how these techniques are used for industrial process control When implementing the ideas in products, it is particularly important to make the systems so that they can be used by ordinary plant personnel. Some ways to achieve this are discussed.

Popular Abstract in Swedish En enkel beskriving av atomen kan utgå från Bohrs atommodell (som emellertid ej är användbar för en exaktare beskrivning): runt kärnan, som består av positivt laddade protoner och neutrala neutroner, kretsar elektroner. Vilket grundämne det är bestäms av antalet protoner i kärnan. Antalet elektroner för en atom är detsamma som antalet protoner i kärnan. Tillförs atomen Atomic data are needed in many different areas of science and technology. Examples of users are the astronomical community and the lighting industry. In this work, the purpose of the projects has been to produce reliable atomic data needed to solve specific astrophysical problems. Oscillator strengths, which are needed when analysing stellar absorption spectra as well as spectra of emission line o

This thesis presents a new technique to prove the convergence of finite difference methods applied to nonlinear Systems arising in computational fluid dynamics. The underlying Systems are either hyperbolic such as the Euler equations or mixed hyperbolic-parabolic like the Navier-Stokes equations. We analyze implicit finite-difference methods. As the argument is based on the concept of consistency
