Technical infrastructures of the society are becoming more and more interconnected and interdependent, i.e. the function of an infrastructure influences the function of other infrastructures. Disturbances in one infrastructure therefore often traverse to other dependent infrastructures and possibly even back to the infrastructure where the failure originated. It is becoming increasingly important

Feedback control has been applied to computing systems, usually taking a designed system and closing a loop to adjust some of its parameters. However, the design of computing systems components as controllers have shown advantages with respect to state-of-the-art techniques, especially in the scheduling domain, where uniprocessor schedulers have been designed as discrete-time control structures. H

Telomeres are natural ends of eukaryotic chromosomes and perform a major role in cell biology. They protect chromosomes from degradation, fusions and the end replication problem. To study telomeres different model organisms are used including a number of yeast species. In this work I present a new species in yeast telomere studies – Saccharomyces castellii. This yeast exhibits a lot of interesting

The paper presents a Matlab toolbox for simulation of real-time control systems. The basic idea is to simulate a real-time kernel in parallel with continuous plant dynamics. The toolbox allows the user to explore the timely behavior of control algorithms, and to study the interaction between the control tasks and the scheduler. From a research perspective, it also becomes possible to experiment wi

This paper presents a dynamic optimization procedure of grade changes of polyethylene production. The optimization is built upon a novel modular Modelica library containing e.g., non-linear DAE models for polyethylene reactors based on models currently used in nonlinear MPC of industrial reactors at Borealis AB. Using Optimica, which extends the Modelica language with constructs for optimization p

Abstract.Over the past decade, a new global regime of anti-corruption has taken shape. Pushed by NGOs such as Transparency International, and with coalitions of international organizations, Western governments, and private business circles, we now have a framework of conventions and regulations that impel governments and international firms to act with integrity and to prevent corruption in busine

This thesis presents studies of molecular motors in interaction with nm-scale structures, as well as the development of a set of tools that can be used for the construction of custom-designed nano-transportation systems. In our studies, we have used the latest nanoscale technology and combined this with advanced results from chemistry and biomedical sciences. We have succeeded in transferring bio

We propose a Tabu-search-based technique for time-constrained SOC (System-on-Chip) test data transportation. The technique makes use of the existing bus structure, where the advantage is, compared to adding dedicated test buses, that no additional routing is needed. In order to speed up the testing and to fulfill the time constraint, we introduce a buffer at each core, which in combination with di
