Iraks avskräckning 1991-2003, Lärdomar från ett misslyckat fall

In March 2003 the Iraqi deterrence strategy came to an end. The US led coalition invaded the country, on contrary of the Security Council ́s recommendations, due to one of the deterrents most important means, weapons of mass destruction (WMD). This qualitative case-study has the scope of Iraq ́s failed interwar deterrence- strategy between 1991-2003. What is deterrence, who was the actual target o

Konflikten i Ukraina och taktiska trendbrott

With this study I seek to investigate if the Russo-Ukraine conflict, yet another example of when new or newly adapted technical innovations, have an impact on tactics. The method for this is to compare the observed use of drones in conjunction with mass fire weapon-systems in eastern Ukraine to the use of new weapons and techniques in the first world war, specifically the larger battles on the wes

Using Natural Language Processing to Identify Similar Patent Documents

The search for prior art documents is an important, but time-consuming task for the patent attorney. Today, these searches are carried out using keywords, which is problematic since inventions often are described using abstract and general terms in the patent applications. In addition, synonyms must be taken into account and formulated manually. This means a risk of relevant documents being overlo

Civilförsvarets betydelse för Sveriges säkerhet - En diskursanalys kring maktfrågan i totalförsvaret

The Swedish preparations for war have decreased rapidly since the end of the cold war. The internationalization of the Swedish Armed Forces, together with the phase out of the civilian defence, was a direct measure of a worldwide peace between nations. However, in recent years, the situation has changed, and the nation faces a specific threat yet again. The purpose of this study is to investigate

Hoten i Arktis med Sverige i fokus

In recent years, the Arctic has attracted focus, news media and authorities have made it clear that tensions in security policies have increased. To gain a further understanding of how Sweden (as a state) relates to the Arctic region, this study examines official sources using narrative analysis through the lens of securitization theory. This study examines how Swedish official threat narratives a

Sjukvårdsmaterielkrisen 2019

From the first of October 2019 there was a new supplier of medical equipment in five regions in Sweden. From the second of October we had a medical equipment crisis on our hands. This thesis aims to uncover why one out of five regions was practically unharmed by the supply shortage and if this was due to active measurements taken by the region authorities or something else. The study uses Lundquis

Implementering av erfarenheter

The aim of this study was to examine the Lessons Learned process used in the Swedish Navy and to identify which factors impacts the process of turning Lessons Identified into Lessons Learned in a positive or negative way. Qualitative methods were used, collecting data from three naval units through open interviews. Four established theories have been used throughout this study. Firstly as the basi

Tröskelbegreppet - Det gränslösa begreppet

The threshold concept is a popular term at the moment in contemporary Swedish defense alignment and defense debate. Terms like threshold, with various meanings and adopted usage can be confusing in what the real definition of the term actually are. The problem with unclear definitions of terms such as the threshold is that it could lead to misconception or in worse case become a word of platitude,

Marinens personalresurs

Försvarsmaktens försvarsgren Marinen rekryterar, anställer, planerar och utvecklar personal i syfte möta de uppdrag och uppgifter som åligger myndigheten. Uppsatsens syfte var att undersöka samordningsmöjligheter och svårigheter genom respondentundersökningar i form av enkäter kring personalplaneringsprocessen inom den militära kontexten. Enkäter skickades till tre olika nivåer inom myndigheten –

Försvarsmaktens militära profession

In 2016 the Swedish armed forces published a control document, Vår militära profession, which specified the new vision of the Swedish military profession. This study’s purpose is to investigate if Swedish officers view on their profession corresponds with the vision from the control document. Nine qualitative interviews have been conducted with officers of the Southern Skåne Regiment. The study h

Improving High-Risk Consumer Credit Scoring with Financial Transaction Data

Credit scoring, the process of evaluating loan applicants with the help of numerical methods, is widely used in the financial sector. When used correctly, it can aid the decision process and lower default rates on loans. New EU regulation has allowed third-party actors to access personal banking information, following the applicant's consent. The increase in available information that financia

Omvårdnadsåtgärder för att minska oro och stress hos barn med autism i samband med röntgenundersökningar

En röntgenundersökning sker i en högteknologisk miljö, som kan vara påfrestande för barn med autism, därför är det av vikt att en röntgensjuksköterska kan tillämpa olika metoder för att minska barnets oro och stress. Syftet med litteraturstudien var att belysa omvårdnadsåtgärder för att minska oro och stress hos barn med autism i samband med röntgenundersökningar. Integrerad analys av nio artiklar

Krishantering och maktpolitik

In the beginning of 2020 the world experienced the most severe pandemic since the last globalization wave. In Scandinavia the COVID-19 outbreak was countered with similar aims but with different measures. When Denmark imposed extensive restrictions Sweden took a completely different path. This study investigates the reason why seemingly equal countries opted such different crisis management strate

Machine Learning Enabled Nonlinear Phase Noise Mitigation for Coherent Optical Systems

In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. The processing scheme was enabled by machine learning, implemented to compensate nonlinear noise in a comm

How does water quality affect paint products?

I detta examensarbete har man undersökt hur olika renheter på vatten påverkar kvaliteten på vattenbaserade färgprodukter. Man har använt sig av två olika renade vatten och kranvatten som kontroll. De renade vatten som användes var avjoniserat vatten och destillerat vatten. Avjoniserat vatten renas genom filtrering och destillerat vatten renas genom kokning och uppsamling av vattenångan. KvaliteteIn this project the effect different water qualities had on water-based paint products were investigated. Tap water was used as a control and deionised and distilled water were used to determine whether the water purity had an impact on the quality of the finished paint products. One intermediate and five finished products were used to investigate the effect of water purity. The intermediate was

Tick data clustering analysis establishing support and resistance levels of the EUR-USD exchange market

Our aim is to use clustering algorithms in order to compute support and resistance levels within an intra-day trading setting. To achieve this we use a tick data set from the EUR-USD exchange market during 2019 as a measure of market activity. Both the Gaussian Mixed Model (GMM) and an altered form of Kmeans clustering will be used as clustering methods where each method will be evaluated using a

Cellular automata analysis of life as a complex physical system

This thesis regards the study of cellular automata, with an outlook on biological systems. Cellular automata are non-linear discrete mathematical models that are based on simple rules defining the evolution of a cell, depending on its neighborhood. Cellular automata show surprisingly complex behavior, hence these models are used to simulate complex systems where spacial extension and non-linear re

Generation and Characterization of Intense Attosecond Pulses

Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. This thesis is about the generation of such attosecond pulses via high harmonic generation (HHG) in argon gas by a terawatt infrared (IR) laser source. The pulses are applied in
