The paper presents Jitterbug, a Matlab-basedtoolbox for real-time control performance analysis. The controlsystem is described using a number of connected continuous-time anddiscrete-time linear systems. The control performance is measured bya continuous-time quadratic cost function. A stochastic executionmodel is used to describe when the different discrete-time systemsare updated during the cont

Neutrophil apoptosis occurs both in the bloodstream and in the tissue and is considered essential for the resolution of an inflammatory process. Here, we show that p38–mitogen-activated protein kinase (MAPK) associates to caspase-8 and caspase-3 during neutrophil apoptosis and that p38-MAPK activity, previously shown to be a survival signal in these primary cells, correlates with the levels of cas

I denna studie insisterar vi över en ny experimentell innovativ idé, nämligen ”live interaktion” via webbkamera. Vi ger, därmed, vår lösning till en bättre och tätare feedback med en hög grad av flexibilitet. Vi jämför våra resultat med campusutbildning.

Popular Abstract in Swedish I den här doktorsavhandlingen presenteras ett datorprogram som utvecklats för att simulera och utvärdera biotekniska processer, där flera processteg kan vara integrerade. Speciellt har en process för framställning av mjölksyra från vetemjöl studerats. Mjölksyra har traditionellt använts i kemi-, läkemedels- och livsmedelsindustrin som t.ex. råvara, surgörare eller konseBiotechnical processes are often integrated to increase productivity and yield. It is difficult to predict the effects of process integration and to find optimum conditions for the process. A valuable tool for the evaluation of a complete process is mathematical modelling. In this thesis, a computer program developed for simulation and optimisation of integrated biotechnical processes is presented

The effect on haemostatic variables by dextran 70, enoxaparin and their combinations, given in doses of 500 ml i.v. and 40 mg s.c. respectively, was studied in a randomised cross-over fashion in twelve healthy male volunteers. Antifactor-IIa activity, antifactor-Xa activity, APTT, factor VIII, vWF, bleeding time and blood counts were analysed over a 24-h period. Dextran alone did not affect antifa

The crystal structures of Bi2.5Na0.5Ta2O9 and Bi2.5Nam-1.5NbmO3m+3 (m = 3,4) have been investigated.ysis of their neutron powder diffraction by the Rietveld anal patterns (lambda = 1.470 Angstrom). These compounds belong to the Aurivillius phase family and are built up by (Bi2O2)(2+) fluorite layers and (A(m-1)BnO(3m+1))(2-) (m = 2-4) pseudo-perovskite slabs. Bi2.5Na0.5Ta2O9 (m = 2) and Bi2.5Na2.5

In service life modeling of concrete, the ion transport in the pore solution is crucial. The main deterioration phenomena associated with ions in the pore solution are (1) corrosion due to external chloride ions reaching the embedded reinforcement bars; (2) carbonation due to presence of dissolved carbon dioxide (which will form carbonic acid with water) supplied from the surrounding air; and (3)

Cross-linking of polyvinylalcohol (PVA) by boronate-containing copolymer of N,N-dimethylacrylamide (DMAA, 1) was studied and compared to cross-linking of PVA by borate buffers in weakly alkaline solutions. The copolymer of M-w = 19,000 g mor(-1) containing 9 mol% N-acryloyl-m-aminophenylboronic acid (NAAPBA, 2) was prepared by free radical polymerization of the monomers, exhibiting copolymerizatio

This article outlines an experimental and numerical study of self-desiccation and chemical shrinkage in Portland cement mortars, with or without silica fume. For this purpose 9 different cement mortars were cast in 90 pycnometers (study of chemical shrinkage and hydration) or 180 glass flasks (study of self-desiccation and hydration). Chemical shrinkage was observed for 14 days and self-desiccatio
