Increasing soft error rates for semiconductor devices manufactured in later technologies enforces the use of fault tolerant techniques such as Roll-back Recovery with Checkpointing (RRC). However, RRC introduces time overhead that increases the completion (execution) time. For non-real-time systems, research have focused on optimizing RRC and shown that it is possible to find the optimal number of

In this paper, physical limitations on antennas are presented based on the holomorphic properties of the forward scattering dyadic. As a direct consequence of causality and energy conservation, a forward dispersion relation for the extinction cross section is established, and isoperimetric inequalities for the partial realized gain and partial directivity are derived for antennas of arbitrary shap

The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years

This study investigates the relationship between the frequency of credit ratings changes and stock return volatility using a dataset of publicly listed U.S. firms with annual credit ratings from the past ten years to construct both cross-sectional and panel datasets across different time windows. The main empirical approach of this thesis is fixed effects panel regression with clustered estimator,

Självhandikappning är en försvarsstrategi som är relativt outforskad och sannolikt underminerar en persons möjlighet att lyckas. Den aktuella studien undersöker samband mellan självhandikappning och HEXACO-personlighetsdragen; Honesty-Humility, Emotionality, Xtraversion, Agreeableness, Conscientiousness, och Openness. Ett mål med studien var att belysa varför vissa personer är mer benägna än andraSelf-handicapping is a poorly understood defense strategy that plausibly undermines a person's chance of success. The present study examines relations between self-handicapping and the HEXACO-personality traits; namely, Honesty-Humility, Emotionality, Xtraversion, Agreeableness, Conscientiousness, and Openness. An aim is to shed new light on why some people are more prone to debilitating self-

CONTEXT: Uptake of organic farming falls short of stated sustainability targets, particularly in highly productive regions where adoption could mitigate environmental impacts of intensive farming. Several hypotheses have been advanced to explain the constraints on adoption, but these have not been assessed within an integrative, interdisciplinary framework.OBJECTIVE: The objective was to develop a

Introduction: Treatment strategies for endometriosis have traditionally been biomedical. There is a need for a more multidimensional understanding of endometriosis and more targeted and individualized treatment interventions, including psychological approaches. Methods: The aims of this study were twofold: (1) to identify key biopsychosocial characteristics in individuals attending a tertiary clin

The Bcl-2 family of proteins governs mitochondrial outer membrane (MOM) permeabilization, a critical step in apoptosis that is dysfunctional in many cancers. Although cellular studies have long implicated direct interactions between the pore-forming apoptotic Bax protein and its opponent, the antiapoptotic Bcl-2 protein in apoptosis regulation, the underlying basic principles behind this control r

This study investigates how decision makers at the fire service responds to different types of information and how it can enhance fire service operations during incidents. Semi-structured interviews were conducted with 47 incident commanders from three countries (Sweden, Finland and USA) to assess the influence of pre-planned, real-time, and predictive information on decision-making. The results i

Location graphs, compact representations of human mobility without geocoordinates, can be used to personalise location-based services. While they are more privacy-preserving than raw tracking data, it was shown that they still hold a considerable risk for users to be re-identified solely by the graph topology. However, it is unclear how this risk depends on the tracking duration. Here, we consider
