As computer systems grow larger and more complex, the task of maintaining the system and finding potential security threats or other malfunctions become increasingly hard. Traditionally, this has had to be done by manually examining the logs. In modern systems, this can become infeasible due to either the large amount of logs or the complexity of the system. By using machine learning based anomaly
Data is a crucial resource for machine learning. But in many settings, such as in healthcare or on mobile devices, there are obstacles that make it difficult to utilize the available data. This data is often distributed between many clients and private, meaning that central storage of the data is inadvisable. Further, image data is often unlabeled and external labelling is impossible due to its pr
Continuous production control is important for the production using Tetra Pak equipment, as problems that are found early in the chain of production can minimize the need for waste greatly. In production of paper straws, a possible production control could be to photograph straws during production, analyse these and predict how good the straw is, using the image. If the predicted performance of th
This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults). The sample with a pu
Iceland is known for its remote location and rough beauty. In their seclusion, the Icelanders have built an independent and peaceful country. They are undeniably a very unique nation, where police officers are not allowed to carry guns, except on special occasions. The society displays a relaxed attitude towards prisons, which are built without concrete walls around. However, faced with the immens
Vi lever idag i ett samhälle som ständigt förändras med bland annat stora tekniska utvecklingar. Detta innebär även att brottsligheten förändras och skiftar med tiden. De svenska processrättsliga principerna är från 1940-talet och har en väldigt stor påverkan på förfarandet i brottmålsprocessen. Med utgångspunkt i omedelbarhetsprincipen och muntlighetsprincipen ska de bevis som man ämnar använda åWe live in an ever changing society with major developments, especially in the technical field. This also means that the crimes committed today are different and more complex than before. The Swedish procedural principles are from the 1940s and they have an important influence on today’s criminal trial procedure. Based on the principle of oral procedure and the principle of immediateness the evide
Object detection is an important tool in computer vision and a popular application of machine learning. One of the main challenges in object detection, and machine learning in general, is acquiring sufficient training data. Many types of data can be hard or expensive to collect and label, or be subject to privacy concerns and regulations such as the General Data Protection Regulation (GDPR). This
The aim of this study was to understand how staff in residential child care experience and relate to their profession and their daily work with the children. The method chosen for this study was semi-structured interviews with eight professionals from three different residential care for children in the southern part of Sweden. To analyse the results, we chose the following theories and concepts;
Rätten att straffa förbrytare ställer höga krav på rättssystemet att ha rättvisa och robusta prövningsmetoder som säkerställer objektivitet och opartiskhet i rättstillämpningen. Sedan Ciceros tid innefattar detta att straffa för uppsåtet bakom handlingar, snarare än handlingars konsekvenser. Men hur fastslår vi uppsåt? Syftet med denna uppsats är att undersöka hur uppsåt hanteras i svensk rätt, oThe legal right to punish perpetrators of crime places high demands on the legal system to have just and robust methods for the application of law, to ensure objectivity and impartiality. Since the time of Cicero this entails punishing the intent of actions, rather than the consequences of actions. But how do we establish intent? This essay aims to investigate how this area is managed in Swedish
Can children really be psychopaths? – A qualitative study about social workers’ view on children with psychopathic traits. The purpose of this study was to investigate how children with psychopathic traits are presented by investigators and therapists in order to gain a greater understanding of the social and cultural opportunities and limitations to approaching the phenomenon of psychopathy in c
Förekomsten av surrogatmoderskap i Sverige ökar, detta trots att Sveriges inställning till surrogatmoderskap alltid har varit avvisande. Den rättsliga regleringen kring assisterad befruktning och fastställande av föräldraskap syftar till stor del till att motverka förekomsten av sådana arrangemang. För att genomgå surrogatmoderskap vänder sig därför svenska personer till utlandet, där metoden är tThe prevalence of surrogacy in Sweden is increasing, even though Sweden's attitude to surrogacy always has been dismissive. The legal regulation regarding assisted reproduction and determination of parenthood is largely aimed at counteracting the existence of surrogacy. To be able to use a surrogacy mother, Swedish citizens therefore turn abroad, where the method is permitted and where they ca

Cranioplasty is surgical repair of a skull bone defect due to a previous surgery or injury. Cranioplasty is most often performed with autologous bone flap, i.e the patient's own saved bone from previous surgery if this is available. If autologous bone is not available then custom procedure is to manually mould an implant using bone cement from the plastic polymethyl methacrylate (PMMA). Manual
In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. In order to make usage of the mmWave spectrum, due to the high path loss it introduces, the beamforming technique is adopted. Beamforming is a method used in high fre
Denna studie ämnar bidra till ökad kunskap inom ämnesområdet strategisk kom- munikation i allmänhet och individanpassad marknadsföring i synnerhet. Mer kon- kret ämnar författarna att ta fram ett underlag för hur företag som är verksamma inom marknadsföring kan jobba i bättre symbios med deras kunder.

More specifically, the authors intend to provide a framework that would allow for a less hierarchical relationship between companies within the marketing industry and their customers. To achieve this purpose, the following research question
Fund companies and banks argue that letting them manage one’s money is a wise decision. They argue that they are able to create substantial growth in value for the investor without requiring any other input than a small fee and an amount to be invested. This essay tests this claim in a two folded analysis. Time series data with historical value developments of 24 out of the 30 largest Swedish equ
Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. The ultrasonic waves are produced and detected by using piezoelectric elements based on e.g. Polyvinylidene fluoride (PVDF)-film or Lead Zirco
Klimatklivet is an investment subsidy, to support measures that will reduce greenhouse gas emissions. Even though Klimatklivet has contributed to climate investments that is estimated to have reduced Sweden’s emissions by 1.3 million tons of greenhouse gases, the investment subsidy has had to endure criticism. Klimatklivet has been accused of not being a cost-effective policy. The objective of t
Urbanisation has an increasingly negative effect on wild bees and other pollinating insects because it results in land-use change and habitat-loss, leading to population declines. We rely on ecosystem services that bees provide and must ensure their survival. Private gardens constitute a substantial part of green spaces in cities, making them important foraging habitats for pollinators. In 2018 Th
