This paper proposes a framework for the planning of the structural integrity and risk management (SIRM) of offshore structures by utilizing the value of information and action (VoIA) analysis. Multiple structural health information sources, i.e. inspections, structural health monitoring (SHM) and damage detection systems (DDS), are modeled in dependency of the information acquirement state. In the
The damping ratio is a key performance measure in systems that can be modelled as networks of masses and springs. We derive a lower bound on this quantity that applies to such networks when the masses are subject to viscous damping. The result allows the size of the damping ratio to be understood as a function of the system parameters. We use this to derive a decentralised criterion which, if sati
This paper presents a new accelerated testing procedure for plastic gears that is based on several different levels of testing. The iterative testing procedure fulfils requests from the product development process. The following criteria are considered for testing: reduced number of tests, shorter test time and reliable results for different applications. The proposed method was applied over the f
An algorithm is said to be certifying if it outputs, together with a solution to the problem it solves, a proof that this solution is correct. We explain how state of the art maximum clique, maximum weighted clique, maximal clique enumeration and maximum common (connected) induced subgraph algorithms can be turned into certifying solvers by using pseudo-Boolean models and cutting planes proofs, an
Nanowire (NW) arrays containing a top segment of GaxIn1–xP are investigated, comparing NWs grown using two different Ga precursors, trimethylgallium (TMGa) and triethylgallium (TEGa). TMGa is the precursor commonly used for the particle-assisted vapor–liquid–solid (VLS) growth of GaxIn1–xP NWs. However, it shows inefficient pyrolysis at typical NW growth conditions. The use of the alternative prec
Whole-exome and whole-genome sequencing (WES, WGS) can generate an unprecedented amount of complex information, making the informed consent (IC) process challenging. The aim of our study was to assess the readability of English IC forms for clinical whole-exome and whole-genome sequencing using the SMOG and Flesch-Kincaid formulas. We analysed 36 forms, most of which were from US providers. The me
In this brief text we look at one instance of how gender norms continue to inform institutional treatment of parents regarding care for children: specifically, at how the exercise of fathers' responsibilities for their children can be discouraged or altogether blocked.
The existing models for the conversion and design of polymer gears are only valid for involute gears. This research was focused on S-gears, a specific type of gear profile which has more favorable contact conditions and greater root thickness when compared to involute gears. S-gears design is currently based on tests, experience, and the use of numerical simulations. Due to the lack of a simple ca
Purpose: The purpose of this thesis is to investigate whether the length of the maturity profile of a firm’s debt has any implications for the capital structure. Theoretical perspectives: A deductive approach, using econometric methodology to examine the correlation ( if any) between the selected variables, and the significance (if any) of that correlation. The output of our econometric model is f
The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation
This thesis project investigates the topic of joint optimization for crest factor reduction and digital predistortion blocks, which are used for digital correction of analogue impairments in digital radio front ends. The work first investigates the effects of joint parameter variation of the above blocks on the global performance and computational cost of the digital chain, given reference CFR and
This thesis explores the provision of memorable digital cultural experiences (MDCEs) for young audiences, thereby addressing the existing gap in the literature concerning the experience economy, digitalization in the cultural sector, and memorability of experiences. Based on qualitative in-depth interviews, the research explores cultural consumption trends, uncovers factors contributing to the mem
The development of generic pharmaceuticals includes extensive data on equivalence with the reference listed drug is required by the European medicinal agency (EMA) and the North American equivalent. Equivalence must be proven for rheology, microstructure, and performance. This is a costly and time-consuming process. To reduce the costs, it is of interest to investigate if the release profile (perf
BACKGROUND. Early and accurate detection of infectious respiratory diseases like COVID-19 and tuberculosis (TB) plays a crucial role in effective management and the reduction of preventable mortality. However, molecular diagnostic tests for these infections are expensive and not easily implementable in resource-limited settings, which suffer the majority of the burden. Lung Ultrasound (LUS) presen
Meningsfull förändring har diskuterats i flera studier, med den återkommande frågan om hur den skulle kunna konceptualiseras och bedömas för att identifiera vad som utgör meningsfull förändring och var den uppstår. Tidigare studier har genomfört statistiska analyser baserade på traditionella betygsskalor (d.v.s. PHQ-9) för att bedöma meningsfull förändring. Det finns inga bevis för att tidigare stMeaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. There is no evidence to be found of previous studies attempting t
With increasing pressure to get rid of the world’s dependence on fossil fuels to reach the world’s climate goals, the use of alternative fuels for propulsion are needed. This is a challenge for the maritime industry, where ferries have good properties to become renewable by the usage of batteries. Their routes are mostly fixed routes and with good infrastructure established at each stop, fully bat
Ansträngningsutlöst andningsfunktionsstörning drabbar främst barn och ungdomar, oftast i samband med idrottsutövning och är vanligare bland flickor än pojkar. Mekanismerna bakom besvären är komplexa och inte helt klarlagda. Enhetliga rutiner för omhändertagandet finns inte. Syftet med uppsatsen var att kartlägga och utvärdera omhändertagandet av personer med dessa besvär vid Röst- och TalvårdsavdeExercise-induced respiratory dysfunction affects mostly children and young people, usually during athletic performance, and is more common among girls than boys. The mechanisms of the disorder are complex and not fully understood. Uniform clinical procedures for examination and treatment of these patients are not established. The purpose of this paper was to identify and evaluate the present care
This thesis describes bio-ethanol production and use for transport fuel in Ethiopia, focusing on current status and potential, barriers, implications and recommendations for a sustainable market. The need for such research is justified as it paves the way for bio-ethanol development in Ethiopia towards a more sustainable path as challenges are surmounted. Bio-ethanol from molasses is identified in
