Detta arbete har syftat till att göra en situationsstudie av dissipation beräknad i HIRLAM, en numerisk prognosmodell, över Danmark och att ge författarna kunskap om fenomenet turbulens. Studien gjordes genom att bearbeta data erhållen från HIRLAM i MATLAB. Den nedersta delen av troposfären där jordytan har en påverkan på atmosfären kallas för gränsskiktet. När vinden blåser i gränsskiktet kommer This case study aimed at analyzing dissipation calculated in HIRLAM, a numerical forecast model, over Denmark and to give the authors more knowledge about the phenomenon of turbulence. The study was done by processing data obtained from HIRLAM in MATLAB. The lowest part of the troposphere where the surface of the earth has an impact on the air is called the planetary boundary layer. When the wind

The main goal of this thesis is to find out, what is a complicated product and if complicated products can be more simplified in their properties, which are these properties and finally to incorporate these properties in the design of an object. The final design will be carried out in a full scale model to understand and test the implemented properties of simplification directly on the product in

This research investigates short-term management fixation to meet performance thresholds through real earnings management. Specifically, we examine management decision-making regarding the trade-off between short-term profitability and R&D’s long-term benefits in Nordic firms. Building on established economic and institutional frameworks, along with the most relevant studies in the field, this

This master thesis was done in cooperation with the Danish district heating company, Vestegnens Kraftvarmeselskab I/S. VEKS is a transmission company supplying heat in western Copenhagen, Denmark. VEKS wanted a global analysis over the possibilities to decrease the cost and carbon dioxide emissions from purchased heat through decentralized accumulation. To cover all economical and environmental re

Givet ett harmoniskt vektorfält u på en begränsad domän kallar vi den mängd där u träder in i domänen för inträdesrand och den mängd där u lämnar domänen utträdesrand. I den första delen av detta examensarbete ställer vi frågan om det är möjligt att ha inre stagnationspunkter och sammanhängande inträdes- och utträdesrand. Svaret i två dimensioner är ‘nej’ för en domän som är homeomorf till skivan.Given a harmonic vector field u on a bounded domain we call the set on which u enters the domain entrant boundary and the set on which u exits the domain emergent boundary. In the first part of this thesis we ask the question of whether it is possible to have interior stagnation points and connected entrant and emergent boundaries. The answer in two dimensions for a domain homeomorphic to a disc i

This study explores how older adults in Copenhagen experience the transition into empty-nest life within the broader context of Denmark’s welfare system and cultural values. Using a mixed-method approach, including surveys, in-depth interviews, home visits and walk-along observations, the study investigates perceptions of the respondents concerning how Denmark’s strong welfare system, community en

Grass pollen allergens, including Phl p 5 from Phleum pratense, are major triggers of seasonal allergic rhinitis, primarily mediated by IgE antibodies. This study investigates the genetic basis and functional characteristics of IgG1 antibodies targeting Phl p 5, possibly derived from type 2 memory B cells predisposed to IgE switching. Using site-directed mutagenesis, we analyzed variants of a high

This thesis investigates particulate matter emissions from a turbofan jet engine operated with fossil Jet A fuel and mixtures of Jet A and sustainable aviation fuel (SAF), focusing on particle size distributions and total emission concentrations. The aim was to evaluate emissions from different fuel blends and sampling points, assess the performance of the designed sampling and dilution system, an

Motor sequence learning research has been primarily concerned with simple frequentist patterns, thereby neglecting the motor system's ability to handle uncertainty and non-deterministic environments. In this study, we combine methods from motor neuroscience and neurolinguistics to study how probabilistic systems are acquired during motor learning. Two groups of young adults practiced a probabilist

Abstract Purpose: To evaluate the midterm outcomes and potential risk factors associated with the fascia suture technique (FST) for closure of femoral artery access sites after percutaneous endovascular aneurysm repair (EVAR). Methods: Between April 2007 and April 2008, 100 consecutive EVAR cases were evaluated retrospectively. A third of the procedures were emergent (16 ruptured aneurysms). Of th

Denna uppsats har via en rättsdogmatisk metod undersökt gällande rätt avseende nödvärn och nödvärnsexcess vid överfall. Den faktiska rättstillämpningen i underrätterna har inte berörts. Rätten till försvarsvåld gentemot brottsliga angrepp tillkommer dels den angripne, dels envar som befinner sig på platsen för angreppet. Denna rätt regleras i nödvärnsstadgandet i 24 kap. 1 § BrB.

In year 2006 Carlings was named the most profitable chain, selling clothes, in Sweden. A year after they ended up on the podium once again. What is remarkable about this result is the fact the company does not exploit any direct marketing or offer a differentiated product compared to its competitors such as H&M and Gina Tricot. How did they manage to do this? The intention of this paper is to

Background: In patients with rectal cancer, when it is not possible to restore bowel continuity with an anastomosis, the optimal surgical method is still a matter of debate. The aim of this trial was to determine 30-day postoperative surgical complication rates after Hartmann’s procedure (HP) versus intersphincteric abdominoperineal excision (iAPE) in patients with rectal cancer who were not suita

Globally, road traffic accidents (RTAs) remain a major cause of death, particularly among individuals aged 15–30 years. While Sweden has been at the forefront of traffic safety through the Vision Zero initiative, in-hospital management remains crucial in determining RTA outcomes. Drawing on North American evidence suggesting improved survival at trauma centres, the Swedish healthcare system has in

Additive manufacturing (AM) is revolutionizing industrial production by enabling the fabrication of complex, customized components with reduced material waste. However, the scheduling of AM machines presents significant challenges in terms of optimizing both time-related performance and energy consumption. This paper introduces a novel multi-objective mixed-integer linear programming (MILP) model

This thesis investigates whether integrating technical market data with fundamental accounting variables improves the out-of-sample predictability of stock returns in the highly liquid S&P 100 universe. Using an expanding window approach from 2010 to 2024, the study compares the performance of regularized linear (Ridge Regression) and non-linear (Histogram Gradient Boosting) estimators against

Denna uppsats undersöker reformen om snabbare lagföring i det svenska rättssystemet och dess påverkan på rättssäkerheten för misstänkta. Reformen infördes i syfte att effektivisera rättsprocessen för enklare brott, såsom snatteri, ringa narkotikabrott och trafikförseelser, genom att minska handlägg- ningstiderna och förbättra myndighetssamverkan. Genom en rättsdogmatisk metod analyseras lagtext, p
