Statisk detektering av minneshanteringsfel i C/C++

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.

Återgivning av ordlistor presenterade med alternerande röster: En jämförelse mellan två återgivningsinstruktioner

In many earlier investigations a recall advantage of auditory lists spoken in a single voice has been found over recall of lists spoken in two alternating voices. One explanation proposed is an organization strategy which makes recall of alternating-voice lists so difficult. The strategy implies sorting same-voice words into same-voice groups at encoding. Based on this proposition, it was assumed that voice-by-voice recall would be better than recall in order of presentation, as then the recall instruction and the organization of items in memory would be in concordance. The present experiment tested and was unable to support this hypothesis.

Tillämpning av Teckal-undantaget på kommunägda aktiebolag. Fallstudie av Göteborgs stad och Gryaab AB

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.

Social kompetens och arbetsminne hos gymnasieelever : Finns det ett samband?

 Den socialt kompetente har hög social status, många vänner, ett funktionellt beteende och sociala förmågor så som empati och hjälpsamhet. Avsaknad av social kompetens innebär bland annat känslomässiga och beteendemässiga problem. I denna studie medverkade totalt 30 gymnasieelever som genomgick två arbetsminnestest samt fyllde i en självvärderingsenkät som mäter social kompetens. Syftet var att undersöka om det finns ett samband mellan en tonårings arbetsminne och sociala kompetens. Studien begränsades till att mäta arbetsminnets fonologiska och visuellspatiala lagringsenheter samt två sociala förmågor; prosocialt beteende och initiativtagande.

Är det utsidan som räknas

In this essay we have approached the problem with retailer brands that copy marketing leaders to get consumers attention in the storeshelf. We have sought to explore how much a designed package would change the consumers opinion of a brand and if this effect is different depending on if the brand is a retailer brand or a market leader. Also we sought to find if this effect would be greater with a salient color on the package. We made a quantitative study and with regression analysis we found that a designed package did have effect on the consumers opinion of the brand, and that the design with the salient color made the biggest effect..

Real-time rendering of large terrains using algorithms for continuous level of detail

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Bike Around

Physical activity can reduce the risk of developing dementia, and studies show that people who already have some form of the disease can get a better memory function and find it easier to perform daily tasks if the activity is performed regularly. People who are diagnosed with dementia are generally not offered physical activity to a high extent, nor is there a wide range of equipment developed to suit the target group.The Bike Around project was launched during a workshop in Copenhagen and was organized by HCH and Techna Science with the aim to develop new training equipment for people with dementia. The workshop resulted in the development of a customized training bike where the user can get a biking experience from his wheelchair or favorite chair. By integrating the pedal movement with a prerecorded movie projected on a screen, the memory can be stimulated both visually and by the activity itself.Our assignment in the project consisted of three parts: design of the bike, movie playback and software programming. During the project a prototype has been created that meets the requirements of ergonomics and usability..

Förmedling och framställning av historia i Tv-spel : En analys av den historiska miljön och atmosfären i Red Dead Redemption

This bachelor´s thesis analyzes the video game Red Dead Redemption and the historical use of the environment and atmosphere in the game. The theory and method used is media research and social memory studies. Two questions were asked: how does Red Dead Redemeption convey and produce the historical environment and the historical atmosphere. Furthermore subqueries/criterias were used to help answer the main questions.The analysis was divided into two parts, the first part we analyze and discuss the games historical environment and the second part analyzes and discusses the historical atmosphere of the game.The conclusion is that both the historical environment and the historical atmosphere is present in the game through picture and sound, the text only works as a guide. The picture and sound live in a symbiotic relationship and depend on each other to fully immerse the player to the game.

Word of Nextopia - en djupare förståelse av Nextopia och hur det påverkar Word of mouth

The purpose of this study is to further develop the understanding of Nextopia, the belief that the next product will always be better, and the effects it has on Word of mouth, both oral (WOM) and electronic (eWOM), and investigate possible causes of this effect. This has been made through an experimental study of responses to two mineral water ads, with a manipulated time frame. First, this thesis supports the fact that there is a general Nextopia-effect on customers being exposed to a future product, which makes them evaluating the product higher in terms of feelings, attitude and intention. Further this study shows that there is also a Nextopia-effect on WOM and eWOM, by customers being more likely to recommend a future product rather than a current one. This propensity to recommend the product also has a relationship with responsibility, which correlates much stronger with WOM than eWOM.

Predatorinducerad fekunditet hos Daphnia pulex vid simulerade årstidsbundna temperaturvariationer

Female growth, number of eggs and egg growth of Daphnia pulex were studied at four temperatures, 12, 16, 18 and 20°C. I hypothesized that female growth and number of eggs would be lower and the size of the eggs larger in the presence of a predator (kairomones) than in its absence. This effect was expected to be more evident at lower temperatures. I could not find any effect of kairomones on female growth, number of eggs or egg size, although there was a weak tendency for an effect on number of eggs. There was, however, an effect of temperature, regardless of predator treatment (i.

Orientalisk institution eller institutionaliserad orientalism? : En arkivvetenskaplig studie av Carolina Redivivas orientaliska handskriftssamling.

This thesis aims to shed light on the collection of Oriental manuscripts at the Uppsala University Library Carolina Rediviva and how the collection is a part of the collective memory. The main question which is central for this thesis is: have orientalism and structures of power influenced the acquisition, arrangement and methods of accessability regarding the Oriental manuscripts? If yes, in what way and why? If no, how has this been avoided?The theoretical framework consists of four approaches: phenomenology, sociology of knowledge, orientalism and power which are applied to the archival concept of collective memory. The main source of material consists of three parts: the historical texts which gives an informational framework regarding the time and place in which the manuscripts were collected, the catalogues in which the manuscripts are described and the transcripted interviews alongside correspondence. Methodologically the thesis is based upon a qualitative method which also partly makes up the foundation for the main material.

Testeffekten som medel för att förbättra läsförståelse?

Swedish school children exhibit deteriorating knowledge results in terms of reading comprehension. Previous research shows that a method to increase the level of knowledge is the use of evidence-based learning techniques. Test based learning generates what is commonly referred to as a test effect, which proved to strengthen the relationship between learning and memory, as well as being applicable to various test formats. The purpose of this study was to investigate whether test based learning, in terms of learning english words leads to increased performance in a reading comprehension test, more specifically a cloze test. The study was based on a within-group design and was conducted three times over four weeks.

Språkliga och kognitiva förmågor hos barn med läs-och skrivsvårigheter : En jämförelse med barn med cochleaimplantat

Children with Reading and Writing Difficulties and Their Language and Cognitive AbilitiesA Comparison with Children with a Cochlear ImplantAbstractThe aim of this study was to examine the cognitive abilities that are important for reading in children with reading disabilities, children with a cochlear implantation and typically developed children. 64 children aged 10-12 years participated in the study. To answer the question at issue we used the following tests: Block Design from WISC III, PPVT III, TOWRE, SL 40 and a few chosen tests out of the SIPS battery. On tests of the lexical access children with reading disabilities performed at the same level as hearing children, while the children with a cochlear implant performed significantly lower. Test of the phonological and complex working memory showed that children with reading disabilities performed significantly higher than children with a cochlear implant, but at the same time lower than typically developed children on the test of phonological working memory.
