This thesis investigates the game of oil shipping; both the market settings and how the players play the game. An important characteristic of the oil shipping market is cycles in the spot freight prices. The cycles are created by the imperfect adjustment mechanisms of supply within the relatively short run, and by that the demand is not perfectly predictable. By a mathematical investigation, I sho

The purpose of this paper is to show how ideas from game theory and economics may play an important role for decentralized controller design in complex engineering systems. The focus is on coordination through prices and iterative price adjustments using a gradient method. We give a quantitative bound on adjustment rates that is sufficient to guarantee global convergence towards a Nash equilibrium

This paper describes the development of a modular system of interactive tiles to support therapists’ in performing therapeutic activities together with impaired children in a swimming pool. Active Surfaces support mobile interactions and dynamic configuration of assemblies of tiles. Each tile represents an interactive unit, able to communicate with other tiles and to exchange data. The tiles can

Streptococcus bovis/Streptococcus equinus complex (SBSEC) is a common cause of infective endocarditis (IE). For IE-pathogens, the capacity to activate and aggregate platelets is believed to be an important virulence mechanism. While the interactions between bacteria and platelets have been described in detail for many Gram-positive pathogens, little research has been carried out with SBSEC in this

I dagens samhälle kämpar företag för att höras och synas i det överflöd av information som finns tillgänglig. Ett särskiljande kännetecken har därmed blivit ett mycket viktigt kommunikationsmedel för företag. I detta kännetecken ligger ofta ett betydande värde i form av goodwill och image och attityd hos förbrukarna. Inte sällan är det hela koncept som förmedlas i ett komplicerat byggande av relat

Digital cognitive assessments have rapidly expanded in Alzheimer's disease (AD) research, offering a sensitive, scalable, and cost-effective alternative to traditional neuropsychological tests. This systematic review examines the validation and utility of digital cognitive assessments in cognitively normal (CN) individuals and explores their potential classification within the US Food and Drug Adm

Popular Abstract in English Fungi are multi-cellular eukaryotic organisms which form thread-like filaments called hyphae. They form reproductive structures called sporocarp (also known as mushrooms). Most fungi are saproptrophs, feeding on dead or decaying material while many are also parasitic, feeding on living organisms. In addition, most vascular plants are always in symbiotic association withEctomycorrhizae is the dominant type of mycorrhiza found in association with tree roots in boreal and northern temperate forests. In this symbiosis, the fungal partner derives energy from photosynthates provided by the host trees and in return delivers soil-derived nutrients such as nitrogen (N). The majority of N in forest soils is embedded in recalcitrant organic matter–protein complexes. Ectomy

The aim of this thesis was to investigate old people's care and quality of life during the last period of life, but also to investigate their own and next-of-kin's experience of this phase. The thesis is based on four studies using separate samples. The sample (n=1198) in study I was drawn from the care and services part of the sub-study ?Good Aging in Skåne? (GAS). The criteria for inclusion in s

Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, polluta

Background: Continuous monitoring of intracranial pressure (ICP) was introduced in the 1950s. For correct ICP recordings, the zero-reference point for the external pressure gauge must be placed next to a head anatomical structure. We evaluated different anatomical points as zero reference for the ICP device at different head positions and their relation to brain centre (BC), foramen of Monro (Monr

This research tries to understand how young career-oriented women perceive social norms about being a female in the business world and how women navigate through competing discourses. Examining the social identity theory that assists us to understand how perceptions of social identities and dominant discourses affect formation of identity. Furthermore, taking leverage from research regarding ident

The present paper argues for more conceptually-laden research on the constitution of place branding as a hybrid form of urban policy. By both drawing from empirical examples and problematizing the extensive research on place branding, this paper offers the view of place branding as an impolitical form of urban policy that emerges as a biopolitical apparatus in an ecology of complex political pract

We propose an alternative method of constructing two Higgs-doublet models free from scalar mediated FCNC couplings at the tree-level. In a toy scenario, we have presented semi realistic textures for the Yukawa matrices, which can reproduce the approximate flavor structure in the quark sector. Presence of flavor diagonal but nonuniversal Yukawa couplings emerges as a distinguishing feature of such

The cliff-edge hypothesis introduces the counterintuitive idea that the trait value associated with the maximum of an asymmetrical fitness function is not necessarily the value that is selected for if the trait shows variability in its phenotypic expression. We develop a model of population dynamics to show that, in such a system, the evolutionary stable strategy depends on both the shape of the f

This thesis delves into Louis Spohr and his First Concerto for Clarinet and Orchestra, Op. 26, starting with an overview of the composer's life and his work. The analysis will provide a better understanding of the meaning and characteristics of this composer's writing during his musical career. The thesis also explores the performance of his concerto that is closer to the composer’s origin

These two volumes of Kosmos (1998) are pedagogical models for the extended vocal techniques performer. Volume 1 has six pieces of various lengths for one to four parts featuring the composer's model of articulation. Volume 2 has fourteen pieces of various lengths for one to four parts dealing with reinforced harmonics. Both volumes can be performed by single players or by a choir.
