Open source software has been gaining popularity, especially among commercial organizations. The broad industry acceptance is in large part due to the demonstrated ability of open source solutions to compete with proprietary alternatives. Using open source software components enables companies to reduce their own development costs, and thus improve software development efficiency. Many open source
Pairing of halide anions with ammonium, as well as with trialkylated and tetraalkylated ammonium cations in water, is investigated by molecular dynamics simulations, which are verified by ab initio calculations and experimental excess chemical potentials. We find that ammonium prefers to pair with smaller halides over the larger ones, while the order is reversed for tetraalkylated ammonium cations
Many flying animals use both flapping and gliding flight as part of their routine behaviour. These two kinematic patterns impose conflicting requirements on wing design for aerodynamic efficiency and, in the absence of extreme morphing, wings cannot be optimised for both flight modes. In gliding flight, the wing experiences uniform incident flow and the optimal shape is a high aspect ratio wing wi
We have experimented with different SOM-based architectures for bio-inspired self-organizing texture and hardness perception systems. To this end we have developed a microphone based texture sensor and a hardness sensor that measures the compression of the material at a constant pressure. We have implemented and successfully tested both monomodal systems for texture and hardness perception, bimoda
Background: The individual contribution of genes in the HLA region to the risk of developing type 1 diabetes (T1D) is confounded by the high linkage disequilibrium (LD) in this region. Using a novel approach we have combined genetic association data with information on functional protein-protein interactions to elucidate risk independent of LD and to place the genetic association into a functional
This thesis is about structure preserving numerical integration of initial value problems, i.e., so called geometric numerical integrators. In particular, we are interested in how time-step adaptivity can be achieved in conjunction with structure preserving properties without destroying the good long time integration properties which are typical for geometric integration methods. As a specific app
Popular Abstract in Swedish De senaste 150 åren har erbjudit en dramatisk utveckling av vår förmåga att sprida både njutningar och smärta, både i form av upptäckter av ämnen såsom TNT och dynamit och framställningen av heroin och Viagra. Denna utveckling har följts av teknologiska framsteg som tillåter studier av dessa kemikalier genom deras interaktion med till exempel radiosignaler eller laser. Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic tech

Abstract in UndeterminedThe point of departure in my story is the contrast between two models of democratic voting process: popular democracy and what might be called committee democracy. On one interpretation, voting in popular democracy is a procedure whose function is to aggregate the individuals’ preferences to something like a collective preference, while in committee democracy what is being
Objectives - To assess long-term functioning and disability after traumatic brain injury (TBI). Material and methods - Individuals (n = 88) in Norrbotten, northern Sweden, who had been transferred for neurosurgical care were assessed with internationally established TBI outcome measures 6-15 years post-injury. Results - There was an improvement in overall outcome from discharge from inpatient reha
This paper analyzes the term structure of interest rates in an exchange-only Lucas (Econometrica 46:1429–1445, 1978) economy where consumers learn about a stochastic growth rate through observations of the endowment process and an external public signal. We allow for deluded consumers, who exaggerate the degree of covariation between the external public signal and the growth rate. With such consum
Abstract in Undetermined Patienter måste kunna lita på att Läkemedelsverket i både i skrift och handling ställer deras rätt till korrekt information över läkemedelsindustrins intressen. Risken är annars överhängande att verkets trovärdighet i läkarnas och allmänhetens ögon urholkas, något som i förlängningen kan få allvarliga medicinska konsekvenser.
In higher plants, thylakoid membrane protein complexes show lateral heterogeneity in their distribution: photosystem (PS) II complexes are mostly located in grana stacks, whereas PSI and adenosine triphosphate (ATP) synthase are mostly found in the stroma-exposed thylakoids. However, recent research has revealed strong dynamics in distribution of photosystems and their light harvesting antenna alo
OH radicals play an important role in pollutant removal in nonthermal plasmas. It is crucial to clarify the behavior of OH radicals in this process. A time-resolved 2-D OH radial distribution was investigated in a pulsed corona discharge by planar laser-induced fluorescence at atmospheric pressure and room temperature. The OH evolutions under different gas components were studied, and the evolutio
Dowry payments from the family of the bride to that of the groom were rarely encountered in Kerala during the early twentieth century, but now are almost universal. Based on an examination of historical documents, including legislative debates, court cases, and reports, the way dowry was explained in the past is compared with the results of 200 contemporary interviews to determine its current rati
Resource allocation in clouds is mostly done assuming hard requirements, applications either receive the requested resources or fail. Given the dynamic nature of workloads, guaranteeing on-demand allocations requires large spare capacity. Hence, one cannot have a system that is both reliable and efficient. To solve this issue, we introduce Service Level (SL) awareness in clouds, assuming applicati
Bell's palsy is an acute unilateral weakness or paralysis of the face of unknown cause. The incidence of the disease is 30 individuals per 100,000 per year. It is a diagnosis of exclusion and other known causes for acute peripheral facial palsy must be ruled out. The prognosis is overall favorable and about 70% of the patients recover completely within 6 months without treatment. Recent randomized
Categorization of rhythmic patterns is prevalent in musical practice, an example of this being the transcription of (possibly not strictly metrical) music into musical notation. In this article we implement a dynamical systems’ model of rhythm categorization based on the resonance theory of rhythm perception developed by Large (2010). This model is used to simulate the categorical choices of parti
Prior studies of IPO underpricing, mostly using agency theory and single-country samples, have generally fallen short. In this study, we employ the knowledge-based view (KBV) to explore underpricing across 17 countries. We find that agency indicators are insignificant predictors, board of director knowledge limits underpricing, and external knowledge both substitutes for and complements internal b
