The paper presents some preliminaryresults on dynamic scheduling of model predictive controllers (MPCs).In an MPC, the control signal is obtained by on-line optimization of acost function, and the MPC task may experience very large variationsin execution time from sample to sample. Unique to this application,the cost function offers an explicit, on-line quality-of-servicemeasure for the task. Base
We evaluate the performance of resonant tunneling permeable base transistors (RT-PBTs) by numerical simulations. Since the current is limited by the barriers, a design with a low doping level around the embedded gate wires is chosen to improve the transconductance. We evaluate the influence of the various geometrical parameters, to optimize the design for high frequency operation. We obtain a perf
Packaging is becoming increasingly important from a marketing as well as logistics perspective, particularly for actors in consumer product supply chains. However, the role of packaging in creating or contributing to the competitive advantage of a company or a whole supply chain is still unexplored to a large extent. This is even the case in businesses where research has shown the benefits of cons
Dynamics of spontaneous decay and corresponding emission spectrum areexactly treated for a system of two identical two-level atoms in 1D.Just a one-dimensional case is considered in order to maximally extractan information on mutual influence of spatially remote atoms through theradiation field. As a result, an effect is revealed and considered indetail that there exist stable (metastable) entangl
The European Spallation Source (ESS) is the European common effort in designing and building a next generation large-scale user facility for studies of the structure and dynamics of materials. The proposed schematic layout of the ESS facility is based on a linear driver (linac) directing the proton beam (5 MW of 2.5 GeV) of 2.8 ms long pulses with a 20 Hz on a tungsten target where neutrons are pr

Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. Because of this, analytical methods with specific p
The paper reviews a number of Cellular Neural Network implementation on a Field-programmable Gate-array. It shows by a number of experiments, how these implementations can be used to create dynamic, autonomous processes for applications ranging from computer games to robot navigation.

Popular Abstract in Swedish Transporter är viktiga för ett fungerande samhälle, men samtidigt innehåller avgaserna från en förbränningsmotor farliga utsläpp som förorenar vår miljö. Kan vi på något sätt hindra att miljön blir förstörd av farliga utsläpp genom förbättrad motordesign? Frågan om global uppvärmning har varit vid liv enda sedan IPCC (Intergovernmental Panel on Climate Change) grundadeThis thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine. The engines concerned are both conventional die
The current extent of knowledge on the supply of carbon compounds to mycorrhizal roots and mycelia, and their subsequent distribution and cycling within the soil ecosystem is reviewed. The carbon requirements of different mycorrhizal fungi are discussed and carbon transfer from host root tissue to the fungal biomass is considered in relation to available information on the amounts and types of com
