Popular Abstract in Swedish Moderna tillverkningsmaskiner är dyra och därför måste dess tillgänglighet och effektivitet ständigt hållas högt. Sådana resultat kan man inte åstadkomma utan tillämpning av en effektiv underhållsstrategi. Förutsättningar för att minska eller arrestera förslitnings hastighet på maskins delar och öka maskinlivslängden är stora vid användning av tillståndsövervakning, (TÖModern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. The main result reported in this thesis is that the rolling element bearing’s mean effective li

This article contains a study of how spatial errors and receiver imperfections affect the angle of arrival estimation accuracy for virtual antenna arrays. A virtual antenna array consists of one receiver element whose location is tracked as the element is moved and in this work, linear arrays are studied. If the location of the receiver is tracked using an inertial measurement unit, an interesting

Over the last years, an expanding family of small regulatory RNAs (e.g. microRNAs, siRNAs and piRNAs) was recognized as key players in novel forms of post-transcriptional gene regulation in most eukaryotes. However, the machinery associated with Ago/Dicer-dependent small RNA biogenesis was thought to be either entirely lost or extensively simplified in some unicellular organisms including Trypanos

Regression testing is expensive and may consume much of organizations’ software development budgets. Thus, it is of interest to reduce the total time devoted to test execution by using test selection techniques. Many techniques have been proposed but few have been evaluated on real-world, large scale systems. In this paper we report on an empirical evaluation of using the class firewall regression

III/V MOS transistors are currently attracting considerable attention. The main driving force is that the advantageous transport properties in III/V materials are expected to increase the drive current in the MOS transistors. Major challenges for the III/V MOS technologies include the growth of high-quality III/V materials oil Si Substrates and the control of the MOS interface. Using the nanowire

Under de senaste åren har lagstiftningen avseende allvarliga våldsbrott kommit att ändrats. Den 1 juli 2014 kom bestämmelsen i 3 kap. 1 § Brottsbalken (BrB) att skärpas på nytt och syftade till att fängelse på livstid i betydligt större utsträckning skulle utdömas. Lagtekniskt innebar ändringen att det i straffskalan för mord lades till att straffet för mord bör bestraffas med livstids fängelse ”oThe provision in the Swedish Penal Code Chapter 3 section 1, which regulates the penalty for murder, has been altered several times during the recent years. The latest alteration of the provision took place in July 2014 with the aim that life imprisonment should be the "average penalty". The provision was altered by adding the wording that the penalty for murder should be life imprisonme

Emojikulturen - Emotionalisering och församtaligande av skriftlig medierad kommunikation är författad av Hannah Busch och Emma Olausson, vid Institutionen för kommunikation och medier vid Lunds universitet. Studiens syfte har varit att utmana föreställningen om att förmågan att kommunicera känslor i medierad kommunikation gått förlorat i och med den ökade digitaliseringen, genom att undersöka vad

G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i

A critical issue for brand fan page marketing is to drive consumer engagement and to or- chestrate enjoyable engagement experiences that consumers desire. Despite the growing amount of research on how various characteristics of brand posts would influence different levels of consumer engagement on the brand fan page in the Western context, the study of consumers’ intrinsic motivations for engageme

År 2009 reformerades det administrativa förfarandet för tillståndsprövningar av vindkraftverk, delvis för att en större vindkraftsutbyggnad skulle komma till stånd men också som nödvändig en åtgärd för att Sverige skulle uppfylla sina skyldigheter i 2009 års förnybarhetsdirektiv. Tidigare hade en ansökning om att få bygga vindkraft inneburit dubbla process- och tillståndsförfaranden enligt både PlIn 2009 the Swedish legislature regarding the administrative procedure applicable to wind energy projects was amended, in part to increase wind power construction but also as a measure to fulfil Sweden’s obligations stemming from the 2009 Renewables directive. As a result, the dual process- and permit procedure under both the Plan and Building Act and the Environmental Code was abolished. Instead,

Bakgrund: Psykisk ohälsa är ett växande hälsoproblem. Kreativa aktiviteter, som körsång, har visats ge personer en rad sociala, psykologiska och hälsofrämjande fördelar. Det finns forskning från andra professioner men det saknas ett arbetsterapeutiskt perspektiv. Att göra en litteraturöversikt är aktuellt för att konstatera vad det finns för forskning idag om sång i grupp och dess inverkan på persBackground: Mental illness is a growing health problem. Creative activities, such as choir singing, have proved to give people a range of social, psychological and health-promoting benefits. There are literature reviews from other professions but there is a void in knowledge when it comes to occupational therapy perspective and occupational science. A qualitative literature review is relevant to e

Den som har ett rättsligt anspråk gentemot någon annan kan väcka talan i domstol för att låta anspråket komma under rättslig prövning. Rätten till domstolsprövning garanteras genom artikel 6(1) EKMR. Det förekommer emellertid att en kärande eller en potentiell svarande ingår avtal med någon utomstående med innebörden att den senare ska föra kärandens eller den potentielle svarandens talan vid domsA person who has a legal claim against another party can bring his claim before a court. The fundamental right of access to court is expressed in Article 6(1) of the ECHR. However, it is common that a plaintiff or a potential defendant enters into agreement with a third party implying that the latter shall bring the claim before court instead of the plaintiff/defendant.

The aim of this study was to examine how the employees at a needle and syringe exchange program understand motivation in their patients and how they work with them to motivate care, treatment and changed habits of addiction. Furthermore, the study is also exploring how the employees are working on establishing a relationship with patients and what role that relationship plays in the process of cha

Projektet Intelligent Survey (IS) utvecklades för att predicera depression och ångest från naturligt språk genom att översätta individers kvalitativa svar från elva öppna frågor till kvantitativa värden som jämförs och prediceras mot skalorna; Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder scale (GAD-7), Harmony in Life scale (HILS) och Satisfaction With Life Scale (SWLS). I saThe project Intelligent Survey (IS) was developed to predict depression and anxiety from natural language by translating individuals' qualitative answers from eleven open-ended questions to quantitative values, which are compared and predicted against the scales; Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder scale (GAD -7), Harmony in Life scale (HILS) and Satisfaction Wit

The present thesis investigated using the random forest machine learning algorithm for wind power forecasting. Meteorological prognoses for wind speed, wind direction, gust winds, and humidity were used. For historical data, wind minimum and temperature was also included. The results were evaluated using root means square error (RMSE), mean absolute error (MAE), normalized mean absolute error (NMA

Background: Over the past quarter century, the incidence of tick-borne encephalitis (TBE) has increased in most European nations. However, the number of humans stricken by the disease varies from year to year. A method for predicting major increases and decreases is needed. Methods: We assembled a 25-y database (1984-2008) of the number of human TBE victims and wildlife and climate data for the St

The purpose of this thesis is to investigate the Swedish stock market’s reaction of asset sale announcements and to see how the stated use of proceeds impacts the announcement effect. To fulfill the purpose the following research questions are asked: Is there an announcement effect associated with asset sales in general? Is the announcement effect, if any, dependent on the stated use of proceeds?

I takt med att teknologin blir en större och större del av vårt vardagsliv ökar även vikten av att säkerställa att dessa system har en hög säkerhet. Säkerheten blir en större del av vår vardag och har alltid varit viktigt för människan. Abraham Maslow placerade säkerhet på andra steget i hans hierarki av behov för en människa, precis under fysiska nödvändigheter som luft att andas, mat att äta ochAs technology advances and is more and more intertwined with our everyday lives, the security of these systems becomes very important. Abraham Maslow famously put safety needs as the second level of his hierarchy of needs, its importance second only to physical needs such as air, food and sleep. To make sure technological systems are as safe as possible there exists threat modeling frameworks and
