This project discusses the effects of recycle streams on the dynamics and performance of chemical plants. The questions addressed are: can the current industry standard tuning methods still be applied to systems with recycle, and if not, how can they be modified? This is approached by analysing the arrest time tuning method when applied to an integrating process with and without recycle. The resul
In robotic systems, uncertainty in model parameters, such as joint stiffness, link lengths, or mass distributions, can significantly affect performance and precision. This thesis investigates the quantification and propagation of such uncertainties using the programming language Julia, with a focus on developing a systematic framework for uncertainty-aware modeling and simulation. It leverages the
There is a significant risk that the current pro-environmental efforts embedded in the prevailing paradigm (shallow ecology) will not be sufficient to solve the increasing number, severity and urgency of environmental/societal challenges – at least they appear to be unable to solve the problems in time. Through literature review and case studies, this thesis author explores how humans having direc
Background: Malignant melanoma and non-melanoma skin cancers are among the fastest increasing malignancies in many countries. With the help of new tools, such as teledermoscopy referrals between primary health care and dermatology clinics, the management of these patients could be made more efficient. Objective: To evaluate the diagnostic agreement and interobserver concordance achieved when asses
Several interactions of cytokines with extracellular matrix molecules are mediated by proteoglycans, such as biglycan and decorin. Using surface plasmon resonance, we show for the first time that tumour necrosis factor-alpha (TNF-alpha) binds to both biglycan and decorin with K(d)s of 0.81 microM and 1.23 microM respectively, a binding that was confirmed by Scatchard plots using a solid phase assa
A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive and communicative development and there is a need for development of methods for assessment. The genera
We study Markov interval maps with random holes. The holes are not necessarily elements of the Markov partition. Under a suitable, and physically relevant, assumption on the noise, we show that the transfer operator associated with the random open system can be reduced to a transfer operator associated with the closed deterministic system. Exploiting this fact, we show that the random open system
We study the few-body physics of trapped atoms or molecules with electric or magnetic dipole moments aligned by an external field. Using exact numerical diagonalization appropriate for the strongly correlated regime, as well as a classical analysis, we show how Wigner localization emerges with increasing coupling strength. The Wigner states exhibit nontrivial geometries due to the anisotropy of th
Highly monodisperse polystyrene/poly(N-isopropylmethacrylamide) (PS-PNIPMAM) core-shell composite microgels were synthesized and further nanoengineered in either ellipsoidal, faceted or bowl-shaped particles. Beside their anisotropy in shape, the microgel design enables an exquisite control of the particle conformation, size and interactions from swollen and hydrophilic to collapsed and hydrophobi
Background Limited information is available regarding genetic contributions to valvular calcification, which is an important precursor of clinical valve disease. Methods We determined genomewide associations with the presence of aortic-valve calcification (among 6942 participants) and mitral annular calcification (among 3795 participants), as detected by computed tomographic (CT) scanning; the stu
We present a consistent way of combining associated weak boson radiation in hard dijet events with hard QCD radiation in Drell-Yan-like scatterings. This integrates multiple tree-level calculations with vastly different cross sections, QCD- and electroweak parton-shower resummation into a single framework. The new merging strategy is implemented in the PYTHIA event generator and predictions are co
The low Lower Cambrian rocks from the Sierra de Cordoba contain one of the best successions in Europe, which consists of well exposed mixed facies with abundant fossil assemblages showing long stratigraphical ranges throughout the Pedroche Formation. These assemblages include diverse Ovetian archaeocyaths, trilobites, small shelly fossils, calcimicrobes, trace fossils and stromatolites. Trace foss
Popular Abstract in Swedish Polymergeler och deras interaktioner med joniska surfaktanter. Olika typer av hydrofoba polymerer och hydrophobmodifierade polymerer tvärbinds kemisk till geler. Dessa geler tillhör gruppen responsiva geler, vilket betyder att gelerna ändrar sin volym under yttre påverkan. Gelernas volymändring studeras vid tillsats av olika joniska surfaktanter, vid tillsats av saltThe response on chemically crosslinked gels and polymer solutions on the addition of ionic surfactants and/or addition of salt at different temperatures have been studied. All polymers studied are water soluble and slightly hydrophobic or hydrophobically modified. Because of their hydrophobicity the polymers have a strong tendency to associate, both with themselves and with surfactants. Another i
Popular Abstract in Swedish I bageriindustrin används emulgatorer i så kallad alfaform för att tårtbottnar ska kunna vispas i ett steg och ändå få en stor luftvolym. Avhandlingen fokuserar på vissa av emulgatorns effekter i produkter såsom kaksmet: Hur skumbildningen påverkas av emulgatormolekylernas packning, hur emulgatorer ändrar svällningen av stärkelsekornen i mjölet, och vilka effekterna bliIn the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a spon
