Bröstcancer är den vanligaste cancerdiagnosen för kvinnor och årligen drabbas över 9000 i Sverige. För att hitta cancern i ett tidigt stadium genomförs regelbunden screening (massundersökning) med mammografi (bröströntgen) för kvinnor i åldern 40–74. Artificiell intelligens (AI) och mekanisk avbildning, Mechanical Imaging (MI), har använts i separata studier inom mammografi för att underlätta granArtificial intelligence (AI) and mechanical imaging (MI) have been used in separate studies in breast imaging. They have individually shown great possibilities within the field of mammography, but the use of the two techniques together have never been evaluated. The artificial intelligence application used in this work was Transpara, a deep learning convolutional neural network. It distinguishes p

The modus operandi of most asset managers is to promise clients an annual risk target, where risk is measured by realized standard deviation of portfolio returns. Moreover, Markowitz (1952) portfolio selection requires an estimate of the covariance matrix of the returns of the financial instruments under consideration. To address both these problems, we develop a data-driven method for covariance

Företagets avdelning för distributionsutrustning håller på att utveckla en lösning för att packa förpackningar i ett rektangulärt mönster i öppna tråg. Lösningen använder sig av en delta-robot med ett vakuumdrivet plockverktyg för att plocka och placera förpackningarna. För att öka robustheten i lösningen vill man ta fram och testa koncept för att automatiskt, och utan operatörsinteraktion, hanterA distribution equipment solution using a delta robot for picking and placing packages in a rectangular pattern into cardboard trays (blanks) is currently under development. In order to increase the robustness of this solution, concepts for handling a variety of performance problems in the grouping or pattern creation area without operator interaction, e.g. toppled packages or missing packages, ne

From a security policy perspective, the grey zone area can be understood as the fact that the line between peace and armed conflict, civil and military, legal and illegal, is unclear and that there are many actors and areas involved. It is easier to observe a grey zone area activity afterwards than to predict it. Based on the theory of securitization, the study aims to describe, in a grey zone con

This work examines how the degree of responsibility, motivation and participation leads to high satisfaction in the work of technical personnel working on First Submarine Flotilla. The work is a theory-consuming case study that, with surveys and interviews, creates the basis for demonstrating through theory how high job satisfaction can be achieved. The result specifies the First Submarine Flotill

In 2018 90 billion tonnes of raw material was extracted globally. It is estimated 20% of this went to waste and with the quickening pace of global metabolism this figure is predicted to have doubled by 2060. In the context of the Anthropocene we need to reduce this incessant cycle of mass extraction and production of waste, change the production systems from linear to cyclic and prove for industri

Tänk dig att du har en tung elastiskt stång som hänger ner från ett fäste i taket och töjs ut, dels på grund av sin egentyngd och dels på grund av en extra tyngd som är fastsatt i botten av stången. Det skulle till exempel kunna vara ett rör som går från en oljerigg (taket) ner mot havets botten där en borr är fastsatt (tyngden). Vi kan styra hur mycket stången kommer töjas genom att justera tvärsWe study the problem first introduced by Verma and Keller in 1984 of how to taper a heavy rope such that its elongation is minimized. The problem is stated as an optimization problem of a functional J[w]. Specifically we provide a proof of optimality for the solution using traditional convex optimization techniques. We also utilize the Legendre transformation when studying the Euler–Lagrange equat

Denna uppsats svarar på frågan varför två kommuner, Karlshamns kommun och region Gotland, fattade två helt olika beslut när de fick samma förslag på att genomföra en affär med projektet Nord Stream 2 år 2016, vilken skulle innebära betydande inkomster och arbetstillfällen. Affären handlade om att upplåta hamnkapacitet och lagringsytor till rör som ingick i bygget av den andra delen av Nord Stream.

In 2010 the Swedish armed forces ended 100-years of conscription and introduced fully employed professional soldiers in their battalions with the purpose to be more usable and have higher readiness. Almost ten years later the turnover has been more than threefold to what was expected when the change was introduced. This study looks into the motivational factors of Swedish professional soldiers. Th

What was the significance of the interaction between Jean Monnet´s personal network and the outcome of the Schuman Declaration? This study, using Allison´s Bureaucratic Politics Model, to investigates Jean Monnet´s personal network during the time of the upcoming of the Schuman Declaration. It identifies the actors that played a decisive role to make the declaration become real. After decades of

”The prisoners taken here were better clothed than any we had seen before. All provided with overcoats and jackets or [sic] a much better material than our own. They were of English manufacture, much darker than the United States uniform, and this furnished conclusive evidence of successful blockade running”. These words were noted on Confederates from Hay´s Louisiana brigade by their Union captor

Swedish security policy has long been centered on a policy of neutrality. This has changed and is now centered on solidarity. A strong will of cooperation with other countries and organizations in order to create security for the nation. This paper aims to explain the current security policy of Sweden by using two of Graham Allison’s theories of decision making, the rational actor and organization

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

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

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

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

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

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

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

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,
