During cold winter days it is likely that people in buildings with older windows or high glass facades experience thermal discomfort due to cold air down draughts. Earlier work has been aimed at finding analytical methods to predict the speed of the airflow in a room and in practice heating appliances are often placed beneath the windows to reduce the draught along the floor. In a study from 2012 Mohammad Parchami developed a method for estimating the required heating power to counteract the downdraught with such heating appliances. In this study, Computational Fluid Dynamics (CFD) was used to evaluate the usefulness of Parchami?s method and also to examine the potential of adapting the depth of the inward window sill as a means of decreasing the down draught.

In the growing concern for the state of the environment more tools are being integrated in the decision-making processes. Sweden actively makes use of environmental impact assessment (EIA), which is supposed to minimise negative impacts of a project, policy or plans on the environment. The EIA process in Sweden still requires certain improvements to be more efficient. In this study actor interaction was analysed with trust being the framework for analysis. The aim is to find out whether it is possible to use trust as a framework for analysis since trust research is very discipline dependent.

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. A recent study has described a small Arabidopsis protein (80), without homology to any described protein, as a phosphorylation target of the MAPK's MPK3/6. Further work established ?-glucan phosphorylase (PHS) as interacting with 80 and described a delayed senescence phenotype for 80 knock-out plants.

Examensarbetet utfördes på Saab Dynamics, ett företag där man har framtagning av bland annat understödsvapen. Produkterna är under ständig förnyelse och utveckling, i strävan efter ständig förbättring. Projektet handlade om att undersöka möjligheterna att ta fram tändsystemsdetaljer till ett lägre pris med funktionsmässigt tillräckliga egenskaper. Under arbetet undersöktes en rad olika tillverkningsmetoder och material teoretisk för att finna lämpliga alternativ till ersättande framtagningsmetoder. Bland annat analys av precisionsgjutning i zink, ett förslag som redan var under diskussion på företaget.

Denna rapport beskriver mitt projekt som utfördes hos Sundbyberg Stad våren 2009. Sundbyberg Stad behövde hjälp med att modernisera sin virtualiseringsinfrastruktur. Jag har i detta projekt undersökt, genom att ta reda på fakta hur Microsofts virtualiseringsplattform Hyper-V fungerar och vilka krav som ställs för att sätta upp en virtualiseringsmiljö baserad på Hyper-V. Utifrån mina undersökningar och kundens krav och önskemål, har jag planerat och implementerat en färdig virtualiseringsmiljö som baseras på Hyper-V. Denna miljö är uppsatt i ett s.k.

This thesis investigates how crime prevention is represented with the aim of preventing and reducing youth crime in two crime prevention strategies for Croydon in England and Stockholm in Sweden for the period 2022-2026. The aim of this thesis is to contribute to increased knowledge and deeper understanding about how crime prevention is represented by prevailing discourse in policy documents against juvenile delinquency in Europe by conducting a comparative analysis. The study was conducted based on Carol Bacchi?s theory ?What?s the problem represented to be?. Three adapted questions from the WPR approach were translated to critically discourse-analytically examine two policy-oriented strategies against youth crime on local level in Croydon and Stockholm.

This essay is about the meeting of the pedagogic mission and the reality of the conditions in preschools. It is about the frustrations that I, as a pedagogue, experience when I cannot fulfill this mission. An example of this is working when understaffed.My purpose is the acknowledgment of two main areas of the curriculum: caring and learning. This essay demonstrates the diversity of the occupation and it ?s constant need of positioning.

In recent years, the characterization of the Third World and its inhabitants in West-originated children?s books has been subject to debate. Media attention around a selection of books has generated discussions on how this relates and aligns with Sweden?s national teaching curriculum. The objective of this study is to explore how a selection of authors, born in Western countries, have characterized and presented the Third World and its inhabitants in its literature.

Nedladdade spel har blivit mer förekommande än vad de var fo?r ett årtionde sedan. Bredbandets framgång har gjort det möjligt att snabbt ladda ner spel och marknaden fo?r digitala spel växer stadigt. I denna studie undersöker vi om konsolspelarnas attityd mot digitala konsolspel skiljer sig från fysiska konsolspel i och med den växande digitala marknaden.

This study takes its starting point in ongoing changes and differences in the global power dynamics. The liberal rules-based world order that has been acknowledged for governing the world with the US as the hegemon of power has been strongly challenged during the last decades. Russia?s invasion of Ukraine can be seen as an example of ongoing changes in the world order, with Russia as a challenger to the US as the hegemon of power. The changes and instability that this has led to for Sweden's national security situation can be seen as a concrete example of how ongoing changes in the world order affect Sweden?s foreign policy.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

Datan som användes i studien hämtades från retriever business och uträkningarna gjordes i Microsoft Office Excel. Variablerna storlek på företag, utvecklingsfas och rörelsekapitalspolicy användes för att kategorisera datan i flertalet tester.Teori: Studiens rörelsekapitalsmått var kassacykeln och lönsamhetsmåttet var bruttovinstmarginalen.Resultat: Studiens resultat visade att det inte fanns något samband mellan rörelsekapital och lönsamhet i 13 av de 24 undersökningarna.Slutsats: Studiens slutsats är att sambandet mellan rörelsekapital och lönsamhet skiljer sig åt hos företag i olika storleksklasser på svenska maskintillverkande företag..

Children are said to be the future of our society. Hence, how we take care of our children is a cause of concern. This is evident in much of the social work that is carried out in Sweden. One of the times when we find children to be the most vulnerable is when they, for different reasons, are separated from their biological families and placed in foster care. Based on the fact that Sweden over the last century has experienced an increased immigration intake we wanted to take a closer look on how this change of the population dynamics has influenced foster care in the country.

Rapporten behandlar utvecklingen av en portal som är tänkt att användas av alla olika delar av en företagskoncern, både som intranät, extranät och extern webbplats. Denna rapport undersöker vad som är viktigt att uppfylla för att skapa en portal av detta slag där kraven på flexibilitet är stora, samtidigt som de olika företagen i koncernen ska ha utrymme att agera både som enskilda företag och som medlemmar i en koncern. Rapporten undersöker även om tekniken SharePoint kan vara lämplig att använda i ett sådant fall samt tar upp alternativ till SharePoint. Slutsatserna är att två aspekter är särskilt viktiga i en portal av slaget som efterfrågas. Dels att portalen utformas med en tydlig struktur och väl definierade nivåer med klara uppgifter, dels att tekniken bakom portalen är anpassningsbar, öppen för vidareutvecklingar och att tekniken är modulbaserad.
