Inlärning i Emotional Behavior Networks : Online Unsupervised Reinforcement Learning i kontinuerliga domäner

The largest project at the AICG lab at Linköping University, Cognitive models for virtual characters, focuses on creating an agent architecture for intelligent, virtual characters. The goal is to create an agent that acts naturally and gives a realistic user experience. The purpose of this thesis is to develop and implement an appropriate learning model that fits the existing agent architecture using an agile project methodology. The model developed can be seen as an online unsupervised reinforcement learning model that enhances experiences through reward. The model is based on Maes model where new effects are created depending on whether the agent is fulfilling its goals or not.The model we have developed is based on constant monitoring of the system.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Library anxiety: en undersökning av psykologiska aspekter kring studenters upplevelser av sitt universitetsbibliotek

This essay investigates the psychological aspects in students' experiences of their university library and the information seeking process. Focus of the investigation is library anxiety, a kind of fear towards the university library with cognitive, affective and behavioural aspects. Twenty students at Uppsala university, who was about to conclude or recently have concluded an academic essay, were interviewed about their experiences of the university library, Carolina Rediviva. Five respondents stated experiences of fear, anxiety and apprehension in the library and it is on these informants that the greater part of the analysis and discussion draws. The essay suggests a model of library anxiety where outer environmental aspects of the library, such as the library environment, roles and routines of the library and library staff, interacts with inner personal aspects of the individual such as personal experiences, intellectual capacity and sensitivity to stress and anxiety.

Mellan fri vilja och datadriven exploatering: En studie om drivkrafter, medvetenhet, makt och ansvar inom onlinecasinomarknaden

This essay examines the limits of marketing strategies in the online casino industry, focusing on how data-driven and advanced marketing practices influence consumer behavior and contribute to problematic gambling consumption. By observing the online casino industry, the study identifies how companies use sophisticated data analysis methods and psychological techniques to attract and retain customers, raising significant ethical and social issues. The study highlights three key perspectives: the consumer's, the producer's, and the legislator's. From the consumer's perspective, it explores how various consumer behaviors, from responsible gambling to problematic overconsumption, are influenced by marketing and gaming experiences. This includes an analysis of how cognitive limitations and psychological biases can lead to irrational decisions and an increased risk of gambling addiction. From the producer's perspective, it examines how gambling companies use marketing strategies and technologies to increase profitability and what incentives they have to take social responsibility according to modern Corporate Social Responsibility (CSR) principles. It appears that companies do not see CSR as a business goal beyond the risk of current and future regulatory compliance requirements and policy changes. From the legislator's viewpoint, the current regulatory framework for the gambling industry is discussed, including the changes that occurred in 2019 when the special monopoly form we had in Sweden was transformed into a license market.

Industriella avloppsvatten i Chile : Identifiering av problem samt förslag på åtgärder

The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

Den positiva hälsovågen : En kvantitativ studie om hälsofrämjande arbete

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Diskretionärt handlingsutrymme : en kvalitativ studie av socialsekreterares bedömningsgrunder vid ansökan om ekonomiskt bistånd

With this study, our purpose has been to achieve profounded knowledge and understanding regarding the use of discretion among social workers specialized in social allowance issues. The Social Services Act, structured as a framework law in the Swedish context, provides the social worker with a certain degree of discretion, in order to enable accommodated decisions depending on client case specifics. This study problematizes these aspects of legal security, and our intention has been to examine which factors impact the assessments social workers carry out in statutory decisions of social allowance applications. To attain this, we narrowed down our intention into a number of distinct and delimitated research questions: (1) Which elements of the client case impact the social worker?s assessment? (2) Which external aspects influence the social worker?s assessments and decisions? (3) How do social workers decide the client?s credibility? In order to establish answers to our research questions, we have utilized a qualitative approach of research by exerting qualitative interviews in addition to a vignette study.

Termisk hantering av litium-jon- batterier i elektriska drivsystem

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden

Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time. I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Produktivitet vid stubblyftning :

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten

Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.

Inverkan av försvagningar på bärförmåga för stålbalkar med långa spännvidder : En jämförelse mellan Eurokod och BKR

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.
