Multi-Dimensional Spectrogram Application for Live Visualization and Manipulation of Large Waveforms

The European Spallation Source (ESS) is a research facility under construction aiming to be the world’s most powerful pulsed neutron source. It is powered by a complex particle accelerator designed to provide a 2.86 ms long proton pulse at 2 GeV with a repetition rate of 14 Hz. Protons are accelerated via cavity fields through various accelerating structures that are powered by Radio-Frequency (RF

Electrical storm in children

Electrical storm (ES) presents a difficult management problem that has predominantly been described in adults and there are limited published data relating to children. We set out to characterize ES in children to assist management based on published literature and own institutional experience. We retrospectively analyzed the records of children presenting with ES to our institution between July 2

Measuring Leadership, Performing Gender : Critical Perspectives on Leadership Assessments and Inventories

Recent research has brought to the fore vital discussions about the logics andassumptions used to evaluate the significance and effectiveness of leadershipdevelopment programs and practices (Vongswasdi et al., 2023). In this chapter,we extend these discussions by reviewing research that considers the logics andassumptions—especially the assumptions about gender and leadership—thatfunction to frame

Kawasaki disease : always straight to the heart?

Kawasaki disease is an important differential diagnosis when evaluating prolonged fever in childhood. Although the aetiology of this vasculitic disease process remains obscure, prompt recognition and treatment significantly reduces vascular complications such as coronary artery aneurysms. Patients presenting with atypical or incomplete diagnostic features remain a challenge. Here the authors descr

Coordination, sensemaking, and idea work : How founding teams pivot their venture ideas

This study offers novel insights into how team structure and flexibility affect pivoting. It details how founding team coordination practices shape individual and collective sensemaking of feedback and efforts to improve a venture idea. Following seven founding teams, we identified how teams with overlapping responsibilities enjoyed the flexibility of both fragmented and holistic sensemaking. This

Development of a DC Beam Model for the First Prototype of the ESS Virtual Machine

The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines.To simulate the proton beam and for crea

Assessing fire safety of fiber reinforced polymer composite ship structures

The environmental impact from shipping is driven by the combustion of fossil fuel. It has great potential to be reduced by use of structures in lightweight fibre reinforced polymer composite instead of steel. This has not been possible for ships regulated under SOLAS, since assessment of fire safety of such a fundamental change is complex. The purpose of this thesis has been to provide for the ass

A Stochastic Theory of Longitudinal Dynamics and Energy Consumption of Road Vehicles

Detailed longitudinal dynamics simulations may be used to predict the energy performance of road vehicles. However, including uncertainty in the operating conditions often implies high computational costs. Model-based formulations, in conjunction with statistical methods, may obviate this limitation by directly accounting for stochasticity, thus eliminating the need for simulating large population

Analysis of key challenges to implementation of FEFO in perishable food supply chain

Implementing FEFO practices has become essential for organizations globally to minimize spoilage, enhance inventory turnover, and ensure compliance with health and safety standards. To aid stakeholders in effectively adopting FEFO, it is crucial to identify and address the challenges involved in its implementation. Through an extensive literature review using the Preferred Reporting Items for Syst

Closing the price gap : Von Thünen applied to wheat markets in 18th century Spain

According to the literature, transaction costs are influenced by several factors, ranging from institutional differences to asymmetric information. However, testing these hypotheses requires rich data not usually available in historical sources. In this study, we use a large-scale census of 1749 to analyze price gaps of wheat across rural municipalities and their local markets in Old Castile. For

Svenskarnas resa från folkhem till folkaktier

Inte bara Investor och Telia – under de senaste tio åren har antalet börsnoterade svenska företag med minst 100 000 ägare växt från 8 till 28. Vad innebär det att de så kallade folkaktierna i dag utgör en så stor del av vår privatekonomi?

Periodic Splinets

Periodic splines represent a specific category of splines, defined across a series of knots on a circle, making them particularly suitable for addressing interpolation challenges associated with closed curves and representing functions defined on a circle. Although the term ‘periodic’ suggests temporal context, the periodic splines can represent any data that have a circle as their domain. This pa

Microscopic behaviour analysis using video recordings : A perspective on vulnerable road users

This thesis investigates the application of microscopic traffic data derived from video recordings to analyse the behaviour of road users, specifically focusing on pedestrians and cyclists in urban traffic environments. This research addresses the critical need for more accurate and proactive methods in the fields of traffic safety, transport system operational performance, and level of service as
