Optimization of Low-Level Controllers and High-Level Polymer Grade Changes

Popular Abstract in Swedish Avhandlingen Optimization of Low-Level Controllers and High-Level Polymer Grade Changes är inom ämnesområdet reglerteknik. Det centrala i ämnet reglerteknik är att styra ett system, såsom en motor, ett teleskop eller en kemisk reaktor, så att det uppför sig på ett önskvärt sätt. Detta görs genom att använda mätningar av systemet, en algoritm som beräknar hur systemet sTwo design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID contr

A dimerized single-chain variable fragment system for the assessment of neutralizing activity of phage display-selected antibody fragments specific for cytomegalovirus.

Abstract in UndeterminedCytomegalovirus (CMV) causes severe sequelae in congenitally infected newborns and may cause life-threatening disease in immuno-deficient patients. Recent findings demonstrate the possibility to alleviate the disease by infusing intravenous immunoglobulin G (IgG) preparations, indicating that antibodies are an effective therapeutic option. Modern molecular methodologies, li

Phase behaviour of active Brownian particles: the role of dimensionality

Recently, there has been much interest in activity-induced phase separations in concentrated suspensions of “active Brownian particles” (ABPs), self-propelled spherical particles whose direction of motion relaxes through thermal rotational diffusion. To date, almost all these studies have been restricted to 2 dimensions. In this work we study activity-induced phase separation in 3D and compare the

Simulation of Nanoindentation Response of Empty and Filled Viral Capsids

The nanoindentation response of empty and filled viral capsids is modelled using three dimensional finite element analysis. Simulation with two different geometries, spherical and icosahedral, are performed using the finite element code Abaqus. The capsids are modeled as non-linear Hookean elastic and both small and large deformation analysis is performed. Force-indentation curves for three differ

Multi-User OFDM Based on Braided Convolutional Codes

Braided convolutional codes (BCCs) form a class of iteratively decodable convolutional codes that are constructed from component convolutional codes. In braided code division multiple access (BCDMA), these very efficient error correcting codes are combined with a multiple access method and inherent interleaving for channel diversity exploitation into one single scheme. In this paper, we describe t

From sign to action : studies in chimpanzee pictorial competence. : Studies in chimpanzee pictorial competence

Many studies of children and apes realized in psychology address issues that are highly relevant to semiotics, but they often do so indirectly, or they use a terminology that is confusing and/or too vague from a semiotical point of view. The studies reported here, however, follow the paradigm of these psychological studies, but they are couched in an explicit semiotical terminology. They involve t

Input och output : ordföljd i svenska barns huvudsatser och bisatser

This thesis investigates the word order in the main and embedded clauses of four Swedish monolingual children, covering the age range 1;3–4;0. Using a generative framework, a quantitative and qualitative analysis focusing on the syntax of verb placement and complementizers is presented. Chapters 1 to 4 offer a background to the thesis. In chapter 1 the aims and the material are presented. Chapter

Weight loss in Huntington disease increases with higher CAG repeat number

Objective: Huntington disease (HD) is a hereditary neurodegenerative disorder caused by an expanded number of CAG repeats in the huntingtin gene. A hallmark of HD is unintended weight loss, the cause of which is unknown. In order to elucidate the underlying mechanisms of weight loss in HD, we studied its relation to other disease characteristics including motor, cognitive, and behavioral disturban

Solvent Dependence of the Electronic Structure of I- and I-3(-)

We present synchrotron-based I4d photoelectron spectroscopy experiments of solutions from LiI and LiI3 in water, ethanol, and acetonitrile. The experimentally determined solvent-induced binding energy shifts (SIBES) for the monatomic I- anion are compared to predictions from simple Born theory, PCM calculations, as well as multiconfigurational quantum chemical spectral calculations from geometries

The effect of mixed liquor suspended solids (MLSS) on biofouling in a hybrid membrane bioreactor for the treatment of high concentration organic wastewater

Biofouling is a crucial factor in membrane bioreactor (MBR) applications, particularly for high organic loading operations. This paper reports a study on biofouling in an MBR to establish a relationship between critical flux, J(c), mixed liquor suspended solids (MLSS) (ranging from 5 to 20 g L-1) and volumetric loading rate (6.3 kg COD m(-3) h(-1)) of palm oil mill effluent (POME). A lab-scale 100

Revisiting Strawsonian Arguments from Inescapability

Peter Strawson defends the thesis that determinism is irrelevant to the justifiability of responsibility-attributions. In this paper, I want to examine various arguments advanced by Strawson in support of this thesis. These arguments all draw on the thought that the practice of responsibility is inescapable. My main focus is not so much the metaphysical details of Strawsonian compatibilism, but ra

Patients with shoulder impingement remain satisfied 6 years after arthroscopic subacromial decompression A prospective study of 46 patients

Background Although arthroscopic subacromial decompression (ASD) is a common procedure for treatment of shoulder impingement, few long term results have been published. In this prospective study, we determined whether the high degree of patient satisfaction at 6 months postoperatively reported by us earlier remained at the 6-year follow-up. Patients and methods We originally reported high patient

Laminar burning velocity of hydrogen and flame structure of related fuels for detailed kinetic model validation

Popular Abstract in English The word “combustion” describes a number of physical and chemical processes, whose common characteristic is an interaction between fuel and oxygen and their subsequent transformation into products, such as CO2 and water. Even though the process is often described as a single chemical reaction between fuel and oxygen, in reality, their chemical transformation requires maThe laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied experimentally and numerically, including its pressure dependence in rich mixtures and temperature dependence

A novel SR latch device realized by integration of three-terminal ballistic junctions in InGaAs/InP

In this letter, a novel sequential logic device based on three-terminal ballistic junctions (TBJs) is proposed and demonstrated. Two TBJs and two in-plane gates are laterally integrated in a high-electron-mobility InGaAs/InP quantum-well material by a single-step lithography process. Electrical measurements reveal that the integrated device functions as a set-reset (SR) latch with voltage gains at

Extreme-right responses to the European economic crisis in Denmark and Sweden : the discursive construction of scape-goats and lodestars

This article examines extreme-right online media as a site of discursive struggle over definitions of the causes, consequences and remedies of the European economic crisis. The authors focus on two Scandinavian countries, Denmark and Sweden, which have seen a rise in extreme-right activities across different arenas and in different media in the turbulent years since the collapse of global financia

Eutrophication-Driven Deoxygenation in the Coastal Ocean

Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many areas of the world's coastal ocean. Climate changes and extreme weather events may modify hypoxia. Organismal and fisheries effects are at the heart of the coastal hypoxia issue, but more subtle regime
