Bayesian learning with Gaussian processes for low-dimensional representations of time-dependent nonlinear systems

This work presents a data-driven method for learning low-dimensional time-dependent physics-based surrogate models whose predictions are endowed with uncertainty estimates. We use the operator inference approach to model reduction that poses the problem of learning low-dimensional model terms as a regression of state space data and corresponding time derivatives by minimizing the residual of reduc

Attosecond science enables the study of ultrafast dynamics on atomic scales, providing fundamental insights into light–matter interaction. This thesis work aims to advance the development and application of an attosecond light source capable of delivering extreme ultraviolet (XUV) pulses with exceptionally high intensity.High-order harmonic generation (HHG) is a nonlinear process where a strong la

Study of initial notch wear during turning of stainless steel with CVD Al2O3/Ti(C,N) coated cemented carbide tools

Notch wear often determines tool life when machining stainless steel. Chemical Vapour Deposited (CVD) Al2O3/Ti(C,N) coated cemented carbide tools are the first recommendation for turning of stainless steel. The CVD coating plays a vital role in reducing and delaying tool wear progress. Hence, it is essential to understand the interaction between the initiation of notch wear and the coating degrada

Impact of cutting tool and workpiece material on initial notch wear in turning

In stainless steel turning, cutting tool life is often limited by excessive localised damage at the depth of cut line, known as notch wear. Previous research revealed that notch wear in CVD (chemical vapour deposition) Al2O3/Ti(C,N) coated WC-Co tools begins as a coating brittle fracture already after 0.3 m of cutting. This paper investigates the impact of cutting tools and workpiece materials on

Play for Democracy : facilitating a space for children’s involvement in urban development

Drawing on the quest to improve inclusion and social sustainability in urban planning process, a holistic approach on citizen participation in urban development is becoming increasingly important. One sector of society whose democratic rights remain overlooked in participatory action is children. It is therefore imperative to develop methods for processing the children’s rights to express their op

The research explores the challenges posed by various radical and insurgent groups, including Marxist and Islamist factions, which employed tactics such as assassinations, kidnappings, and sabotage. It also analyzes the role of the Natio

What drives Generation Z to choose green apparel? : unraveling the impact of environmental knowledge, altruism and perceived innovativeness

This study proposes to determine the influence of ‘Environmental Knowledge’ (EK), ‘Altruism’ (Atr), ‘Consumer Confidence’ (CC) and constructs of ‘Theory of Planned Behaviour’ (TPB) like Attitude” (Atd), ‘Subjective Norm’ (Sub) and ‘Perceived behavioural control’ (Pbhc) on consumers’ intention to purchase ‘Green Apparel Products’ (GAPI). Moreover, the moderating effect of ‘Perceived Innovativeness’

A feasibility study of the internet-based intervention “Strategies for Empowering activities in Everyday life” (SEE 1.0) applied for people with stroke

BackgroundTo enable people with stroke to achieve an active everyday life under altered conditions, the development of self-management programs is essential to facilitate the process of change that individuals must undergo. To improve access to self-management, internet-based solutions have been proposed. The aim of this study was to evaluate the feasibility of a novel internet-based intervention,

An Interdisciplinary Model to Foster Existential Resilience and Transformation

Existentiella hot, inklusive hot mot jaget, samhället och planeten, förekommer genom hela livet och utgör en central del av den mänskliga erfarenheten. För att sammanföra kunskap och begrepp om hur människor kan hantera existentiella hot på ett adekvat sätt sammankallade vi en tvärvetenskaplig arbetsgrupp bestående av åtta forskare från fälten psykologi, systematisk teologi, praktisk teologi, reliExistential threats, including threats to the self, society, and the planet, are present throughout the lifespan and form a core element of the human experience. To consolidate knowledge and constructs about how people can adequately respond to existential threats, we convened an interdisciplinary working group, which consisted of eight researchers from the fields of psychology, systemic theology,

Boendehygien i välfärdsstaden : Problematiseringar av bostadsfrågan i Malmö ca. 1900–1910

1911 beslöt stadsfullmäktige i Malmö enhälligt och utan debatt att införa en kommunal bostadsinspektion. I denna artikel undersöks bostadsinspektionens härkomst genom att följa olika problematiseringar som inspektion sades lösa hos stadens förvaltningar, den lokala arbetarrörelsen och Fredrika-Bremerförbunds-kretsen i Malmö. Undersökningen visar att urbana aktörer som delvis befann sig utanför parIn 1911 the Swedish city of Malmö got its first housing inspection service. It was put forward in a motion by two social-democratic city councillors and supported by conservative councillors as well as by the women’s movement. The vote in the city council passed unanimously and without discussion. This article focuses on how the question of housing was articulated in a way that meant inspections w

The association between personality traits and myocardial infarction- A European cross-sectional study

Background: Myocardial infarction (MI) is a serious condition that increases with age. It is valuable to identify the reasons why some are affected, and possibly, why different personality traits can be associated with an increased or decreased risk for myocardial infarction. Methods: This is a cross-sectional study based on wave 7 data from the Survey of Health, Ageing and Retirement in Europe (S

Lysozyme revisited

Lysozyme is a model system for crystallographers. In this issue of Structure, Ramos et al. report atomic resolution neutron structures of lysozyme, which unambiguously show the protonation states and hydrogen-bonding networks of the active site. This resolves mechanistic questions that have been debated for decades and provides a unique view to a protein at atomic detail.

Factors influencing incumbent energy firms’ radical innovations implementation – A review

To address the challenges of energy transition necessary for sustainable development, incumbents must implement innovations, some of which are radical compared with their current competence-base or market solutions. This requires a thorough understanding of the prerequisites for implementing innovation. The literature on the factors influencing incumbents' implementation is vast and dispersed acro

Knowledge, attitudes, and practices of transcutaneous electrical nerve stimulation in perioperative care : A Swedish web-based survey

OBJECTIVES: Transcutaneous electrical nerve stimulation (TENS) is a noninvasive adjunct to multimodal pain management for acute postoperative care across various surgeries. Despite extensive evidence supporting its efficacy, TENS remains underutilized in clinical practice. This study aimed to assess the knowledge, attitudes, and practices of healthcare professionals regarding TENS in perioperative

The method of moments for multivariate random sums in the Poisson-Skew-Normal case

Multivariate random sums appear in many scientific fields, most notably in actuarial science, where they model both the number of claims and their sizes. Unfortunately, they pose severe inferential problems. For example, their density function is analytically intractable, in the general case, thus preventing likelihood inference. In this paper, we address the problem by the method of moments, unde
