Kvaliteten på kalkcementpelare, kc-pelare, varierar ofta. Det är vid design- och tillverkningsprocess svårt att säkerställa den slutliga kvaliteten och egenskaperna kan vara olika inom och mellan pelare. Den stabiliserade jordens geologiska förhållanden inverkar, liksom bindemedel och tillverkningsförfarande. I Sverige är kc-pelare en vanlig förstärkningsmetod i stora infrastrukturprojekt och det

Sedan år 1895 då Wilhelm Conrad Röntgen uppfann joniserande strålning så har den använts på många olika sätt inom sjukvården, bland annat inom bilddiagnostik. Det är viktigt att en röntgensjuksköterska har en patientcentrerad vård där information och kommunikation med patienten utgör grunden för ett bra patientbemötande. Under det korta mötet kan patienten ställa frågor angående undersökningen och

Covert surveillance officers lack special equipment to carry their essential tools during their surveillance jobs. Officers were interviewed about scenarios, needs and the current equipment as well as solutions. It was apparent that it could be problematic to carry essential tools in an organized and concealed way. A generic bag that anyone could carry without looking out of place was developed th

The Swedish Sea Cadet Corps (Sjövärnskåren / SVK) is a unique voluntary organisation with potential to greatly contribute to the Swedish society in times of crisis. The unique feature of SVK being the only voluntary organisation in Sweden that operates in the maritime domain, does not come without problems. I have in this study made clear to the reader where the problem lies and why there are prob

Automatlarm kan rädda många liv och har hjälpt räddningstjänsten att göra nödvändiga insatser på plats, även om fördelarna är många finns det larm som inte är befogade och som orsakar kostnader för samhället. Syfte med den här studien är att genom intervjuer diskutera kring automatlarm, dess för- och nackdelar och genom litteraturstudier analysera olika ingående parametrar. Material och metod: StAutomatic alarms have saved many lives and have helped the emergency services to make the necessary efforts in place, although there are many benefits, there are alarms that are not justified and that cause costs for the society. The aim of this study is to, through interviews, discuss about automatic alarms and its advantages and disadvantages and through literature studies analyze different inpu

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
