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.

There are several known instances of megalithic graves being rebuilt and reused already in prehistoric time. The aim of this study is to investigate the phenomenom of megalithic reuse through the theorethical framework of social memory. Focus lies on two graves in southern Sweden; Firse sten in Falbygden and Skepparsl?v 10 in Scania. The two graves were originally constructed as passage graves but have in different ways been remodified into gallery graves.

This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..

The aim of the study was to through a qualitative method with two focus groups investigate how young women percieve that their identity creation is influenced by them reading celebrities Blogs and in that case, whether this type of Internet activity affect their autobiographical memory, the foundation for personal identity. Since the main task of the autobiographical memory is to give the ego and its social mode a foundation by sharing memories with others, the Internet activity should be seen as an important factor for the identity formation of young people. Today, the young spend equally mauch time being connected to various media as they do socializing with family and friends. The results indicate that young women view the world and lifestyle that known Bloggers expose intheir Blogs as a kind of ideal. The young women got an aha reaction when they realized that what the Bloggers expose is not always equal to the real life..

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

Syftet med studien är att undersöka samband som visas tydligt hos elever i både matematiksvårigheter samt fonologiska svårigheter. Studien har genomförts på elever i årskurs 7 som uppvisat matematiska såväl som fonologiska svårigheter. Resultatet baseras på en filmad observation där eleverna fått lösa ett urval uppgifter konstruerade utifrån svårigheter gällande grundläggande taluppfattning och aritmetik. Elever med fonologiska svårigheter såväl som bristande arbetsminne visar sig ha svårigheter när det gäller att automatisera tabellkunskap såväl som utföra beräkningar gällande de fyra räknesätten..

Mentaliseringsförmåga innebär förmågan att ta en annan persons perspektiv, att förstå hur någon annan tänker och känner. Det innebär även att förstå de egna tankarna och reaktionerna relaterat till andra personers tankar och känslor. Det är viktigt med en välfungerande mentaliseringsförmåga för att kunna samverka med andra individer och sin omgivning på ett pragmatiskt och ändamålsenligt sätt. Det finns flera olika förmågor som kan vara viktiga för mentaliseringsförmågan, i vilken grad de påverkar är dock fortfarande oklart. Syftet med detta arbete var att undersöka mentaliseringsförmågan och dess samvariation med andra kognitiva förmågor hos barn i åldrarna 6-7 år.

The purpose of this study was to investigate whether cannabis use can affect cognitive functions. The method that was chosen to answer the purpose of the study was a general literature review. Article search occurred in the databases PsycINFO and PubMed. Nine articles were selected based on the study?s inclusion criteria.

The purpose of this examination is to investigate how Judisk Krönika, a periodical which was introduced in 1932 with the aim of disseminating Jewish culture and tradition in Sweden, uses history to make comments about its role in contemporary history, specifically during the first two years of the First Intifada. A second purpose was to examine how this use of history differed from results shown in earlier studies comprising the 1960s and the 2000s. The method in use is qualitative; the source material has been read thoroughly and scrutinized in search of the authors open and hidden messages and intentions. The main finding shows that four major themes could be identified: anti-Semitism(anti-Zionism); memory; ethnonational and media. The most dominant theme during the 1980s, as opposed to the 1960s and the 2000s focus on Zionism and Jewish culture respectively, is memory, that could be described as hegemonic and as a part of a existential use of history, which aims for survival and preservation of the Jewish culture in times of conflict..

Uppsatsen handlar om spelet Memory där vi utgår från vissa regler som gör det möjligt att räkna sannolikheter av olika strategier. Vi använder oss av 2 strategier, säker och vågad strategi, för att utifrån olika positioner i spelet beräkna hur många par en spelare kan förväntas få. Vi gör en jämförelse mellan strategierna och undersöker vilken strategi är bäst att använda sig av i olika lägen i spelet. Det vi har gjort i vårt arbete är att utveckla ErikAlfthans [1] grundidé, att spelarna har oändligt minne och att spelet bara innehåller par. Där har vi gjort två förgreningar där den ena handlar om att spelarna har begränsat minne.

AbstractThe purpose of the study was to examine if manual signs used as support to spoken and written language can be a god mnemonic for learning of word-pictures. I performed my study as an experiment in which I made a Memory game with word-pictures. I played the game with the children twice. The first time, we played without manual signs and the second time I used sign as a support. I observed the children and noted the words they learned to read with and without the support of manual signs.

Gävle var en av de platser som fick mest radioaktivt nedfall efter Tjernobylolyckan 1986. Syftet med vår undersökning är att försöka få en förståelse för hur detta har påverkat kvinnor som bodde i Gävle 1986 och hur de känner idag. Vår frågeställning är vilka minnen de idag har kvar sedan tiden då olyckan hände och vad det betyder?Memory-work är utvecklad av Frigga Haug inom feministisk forskningstradition. Metoden är induktiv, såtillvida att resultaten tolkas utifrån de minnen som kommer fram i undersökningen och inte från färdiga teorier, och resultaten kan leda till nya frågeställningar.

Det här examensarbetet är baserat på idéer ur ett uppdrag från företaget Saab Aerotech men är ett eget arbete.Målet var att undersöka om det finns behov av ett verktyg som statiskt kan detektera dynamiska minneshanteringsproblem, som till exempel minnesläckage, i applikationer skrivna i C/C++. På grund av att minneshanteringsfel i C/C++ länge har varit ett känt problem undersökte vi detta och de befintliga lösningarna till det.Vi fann två metoder till lösningar som de flesta verktyg använde sig av; statisk och dynamisk detektering. De flesta verktyg löste problemet genom att dynamiskt detektera minnesläckor och andra brister som till exempel buffer overflows. Ett verktyg löste dock problemet genom att statisk detektera minneshanteringsfel i källkoden för applikationerna. Eftersom alla befintliga lösningar har någon form av ineffektivitet så har vi undersökt möjligheten att utveckla ett mer effektivt verktyg.

In this essay the aim is to look at difficulties in preservation of buildings in general, andespecially the ones of the modernist era. To navigate in this huge field the study is narroweddown to take place in Finspång, a small Swedish town. In Finspång there was a swimmingpool facility built in 1967. In 2003 the facility was closed down due to its unusable conditionsand then after seven years with discussions of different plans about what to do with thefacility it was demolished in 2010. This case is the base in the essay, and why it was notpreserved.The purpose of this essay is to look at what the people in Finspång think about preservation ofbuildings with the demolished swimming hall facility as base, and what impact materiality hason questions regarding preservation, cultural heritage, memory and history.
