We have implemented an Intelligent Tutoring System (ITS) prototype for teaching multi-column addition and subtraction to children aged 5-10, using a digitalized version of the Montessori bank game exercises. An Intelligent Tutoring System is a piece of software that teaches a certain subject to its users, and that typically uses artificial intelligence related algorithms to personalize the educati
Credibility assessment of testimony is a very important part in the asylum adjudication procedure. The credibility assessment is intended to tell decision-makers whether they should accept the facts as supported by the applicant’s statement. Only those parts of the statement which are recognized as credible will then be considered in determining the validity of the asylum claim. This thesis exam
Optical DNA mapping is a technique for obtaining fast DNA sequence dependent barcodes by observing the stained DNA with a microscope, while it is held stretched inside a nanochannel. Noise plays an important role in optical maps and can significantly change the features in a barcode. One way to reduce random noise is to time average many time frame measurements. This method is efficient but requir
Globalization has led to an increase in competition between places in hopes of attracting mobile capital and investments as well as new inhabitants and tourists. Nature-based tourism has become one of the most steadily growing markets for tourism in Europe. In order for a place to be attractive it has to have a brand that can be constructed depending what sort of resources a place has. A place is
För många innebär datorspel att kliva in i den fiktiva värld som spelet skapar och på så vis undgå verkligenheten. I forskningssammanhang är det precis tvärtom, då är datorspel eller mikrovärldar som det också kallas ett sätt att simulera verkligheten. I detta examensarbete har möjligheten att använda datorspel för studier inom riskhanteringsområdet undersökts. Då det tidigare inte fanns någon miIt has been shown that it can be difficult to study decision making in a risk management context when traditional methods are used. An alternative to traditional methods is to use micro worlds. A certain type of decision making in the risk management context is about investments in capability which has been studied in this thesis. The aim of the project is divided into two parts, where the first p
Med elasticitetsteori kan man inte beskriva hur en statiskt obestämd konstruktion där materialet kan plasticeras går till brott. Enligt elasticitetsteori och ett antagande om ett sprött brott vid en viss spänning går en konstruktion till brott så fort denna spänning uppnås i det högst belastade snittet. Det som egentligen sker är att materialet plasticeras vilket leder till en momentomlagring. Kon
Avfall påverkar miljön negativt på många olika sätt. Det förorenar, skadar djur och producerar växthusgaser. Stor vikt bör därför läggas på att samla in avfall för att förhindra att det förstör naturen. I Sverige bildas det år efter år ton av avfall som behöver omhändertas. En del återvinns men en klar majoritet förbränns. När man analyserat vad som slängs i restavfallet ser man att mer än hälften
Kvantmekaniken är den fysik som beskriver våra minsta partiklar - en mikro-skopisk värld där fenomen som inte alls är naturliga i vår större värld existerar. Genom att undersöka "interferens", ett fenomen som endast vågor och inte partiklar kan ha testar vi kvantmekanikens lagar med attosekundfysik. Människan har länge försökt förstå hur världen fungerar, redan i antikens Grekland fundeQuantum mechanics is used to describe the world at the microscopic scale and below. It is also the theory that has been the most debated but also the one whose predictions has been tested with the highest accuracy. This theory relies on a set of postulates that lay the foundations for all its predictions. One of these postulates is Born’s rule, which defines the probability to measure a quantum sy
Proteases are a group of enzymes that are involved in breaking down larger proteins into smaller polypeptides or single amino acids, and they are used in various applications. In this project, the potential of budding yeast Saccharomyces cerevisiae as host for the construction of protease libraries is evaluated. Three model proteases of bacterial origin are used to evaluate transformation efficien
Brinnande bilar, drunknande isbjörnar och träd som dör ut - det är detta som en del föreställer sig när det gäller global uppvärmning. För att förhindra att detta sker, behöver fossila bränslen ersättas i framtiden. En möjlighet är att använda biobränslen istället, fast problemet är att de innehåller mycket metan. Detta är tyvärr en farlig växthusgas som måste vidarebearbetas i förbränningsanläggnThe study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. This thesis contributes to the understanding of that reaction in a 5 mbar environmental pressure regime over a polycrystalli
The purpose of this study is to analyze and examine the experiences of social workers working with handling clients' trauma and exposure, using the word secondary trauma. We are focusing on analyzing the effects and consequences of working with clients that have been met with or currently are going through difficult situations. The research questions that were used are the following: “How does
This study investigates Swedish critical entities (CEs) ability to maintain function during up to three months of electricity supply disruptions. It also examines possible improvement measures, and how contextual cases (grey zone, heightened state of alert, war) influence CEs’ ability to maintain function during electricity supply disruptions. Expert elicitation was conducted with experts from eig
Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. A typical pulse compression method developed at the Stanford Linear Acceler
Värmeväxlare är system som ofta används i många olika tillämpningsområden så som kylning, uppvärmning, ventilation eller andra områden där man strävar efter att maximera värmeutbytet mellan fluider. Vanliga tillverkningsmetoder för värmeväxlare inkluderar hydraulisk pressning av värmeöverförande plattor, eller att på andra sätt skapa värmeöverförande ytor av rör, korrugerad plåt eller liknade mateHeat exchangers are systems commonly used in many different applications such as cooling, heating, ventilation, and other areas where maximizing the heat transfer between fluids is desirable. Common manufacturing techniques of heat exchangers include hydraulic pressing of heat-transferring plates, or otherwise creating a heat-transferring area of pipes, corrugated sheet metal, or similar materials
Behovet av avancerad rening genom till exempel ozonering eller aktivt kol på avloppsrenings-verk blir tydligare i världen som följd av höga uppmätta nivåer av läkemedelsrester i recipienter. I länder som Schweiz är implementeringen redan idag lagstadgad och också i Sverige förväntas inom en överskådlig framtid krav införas på avlägsning av organiska mikroföreoreningar från avloppsvatten. I dagslägThe need for advanced wastewater treatment using for example ozonation or activated carbon is becoming exceedingly apparent because of high measured concentrations of pharmaceutical res-idues in recipients all over the world. In Switzerland for example there is legal requirements for the implementation of advanced treatment and within the foreseeable future also in Sweden the demands on the remova
Den här uppsatsen har behandlat en ny variant av haloeffekten som vi benämner personlighetsbaserad kompetenshalo. Den handlar om att personlighetsbeskrivning påverkar bedömning av kompetens. Studiens frågeställning var om det fanns någon skillnad i den personlighetsbaserade kompetenshalons styrka beroende på om individen som skattas tillhör en ingrupp eller ej, där grupptillhörighet kategoriseras This thesis examined a new variant of the halo effect, which we call personality-based competence halo. It concerns personality description influencing the judgment of competence. The study investigated whether there was any difference in the strength of the personality-based competence halo depending on whether the individual being assessed belongs to an in- or outgroup, whereby age was the varia
Uppsatsen handlar om konkurrerande kollektivavtal. Då arbetsrätten lämnar detta relativt oreglerat i lag präglas området främst av rättspraxis. Arbetet presenterar de parter som slutit respektive kollektivavtal, introducerar begreppet andrahandsavtal och förklarar innebörden av att kollektivavtal konkurrerar med varandra. Det uppstår regelbundet frågor som handlar om konkurrerande kollektivavtal iThis essay is about competitive collective agreements. Since Swedish labor law leaves this relatively unregulated in legislation, the field is primarily characterized by legal practice. The work presents the parties that have entered into respective collective agreements, introduces the concept of the secondary agreement, and explains the meaning of collective agreements competing with each other.
