Matematiska färdigheter hos elever med lässvårigheter i årskurs 4
Reading difficulties is the most common learning difficulty in the western world and it is common that people with reading disabilities also exhibit arithmetic difficulties. Different theories about the cause of the relationship exists, one theory describes the importance of good phonological ability in reading as well as in arithmetic, while another theory describes the importance of a reliable number system and that only a subgroup of students with reading disabilities also have difficulties with arithmetic. The purpose of this study is to investigate how students with reading difficulties (RD), without any known mathematical difficulties, perform on mathematical tasks relative to a control group. The study was theoretically grounded on the Triple code model (Dehaene, 1992), which is a model for numerical information processing that describes how various numerical and arithmetic tasks are processed through three distinct representation systems in the brain, a verbal and a visual representation system and a quantity system. Reading skills, phonological skills, arithmetic skills and number processing skills were examined in 61 students through a variety of tests.
Teknisk undersökning av stafflimåleri ? Med fokus på två dörröverstycken från Röhsska museet
This bachelor thesis is a study in the analysis of paintings with focus on the technical exami-nation within the framework of ATSR. ATSR is a methodology based on an interdisciplinary study with the aim of putting the object in its context.The study is based on questions concerning which information the object can give, how we access this information and how it can be put in a larger context. My thesis contains three major parts. First a short overview of methods of analysis used in this form of investigation is presented. This is followed by two case studies which exemplify the technical investigation.
En utredning av tekniken "mobile mapping" i kommunal verksamhet
This thesis work is intended to analyze whether the municipalities has a need for the new technology of mobile mapping.Mobile mapping consists of the technologies of laser scanning, photographing and positioning of streets and roads in city environment and in the countryside. When these technologies are operating together a georeferenced three-dimensional image model is created, which has specific coordinates that states its position on the surface of the earth. Thanks to the laser scanning process even measuring can be performed in this model.The municipal sector consists of many different departments which use visual spatial information. These departments are an interesting target group for this system. Specific departments within the municipal sector, which we considered were the most suitable, have been selected.
Tilltal i bild och text : En studie av gymnasieskolors hemsidor ur ett kommunikationsperspektiv
Due to political decisions regarding the Swedish school, public and independent schools booth face the need topromote themselves in the quest for new pupils. This study aims to, from a communications perspective, examine how four selected upper secondary schools address their target audience; the pupils?to?be, on their homepages. Additionally, I intend to investigate whether, and if so, how, said addressing can be connected to the different target groups applying to the schools in question.The questions asked in this study regard the way in which the selected schools describe themselves on their homepage; how do they use the textual and visual content to address their audience, and can there be disagreement between the meaning of the text and that of the image? To answer these questions, I use a theoretical base made out of visual communication and semiotic as well as rhetorical analyses.The methodological procedure is a qualitative approach on the matter, allowing me to understand the ?what? of the content on the homepages, as well as the ?how? it?s being communicated.
Matting of Natural Image Sequences using Bayesian Statistics
The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.
TECHNOLOGY MEETS THE EYE : Utveckling av system för att jämföra eye tracking data med visuellt stimuli
The purpose of the project was to make a system that could extract data from a mobile eye tracker and make it comparable with data from visual stimuli. The produced system was programmed in Java and provided all the necessary parts that were required to achieve the purpose. This provides a foundation for further research to determine whether the eye tracker is sufficiently accurate to diagnose Parkinson?s disease..
Online visual merchandising -ur ett konsumentperspektiv
Denna uppsats handlar om modeföretags online visual merchandising ur ett konsumentperspektiv. Vi har undersökt vad konsumenter anser vara viktiga aspekter ur perspektiven miljö, navigering och produktpresentation för att de ska finna en e-handelssida attraktiv. Tidigare forskning visar att för en kund ska genomföra ett lyckat köp på ett modeföretags e-handelssida krävs det att den virtuella miljön är väl utformad. Dock fann vi ett gap i tidigare forskningen där teorierna inte var prövade utifrån ett konsumentperspektiv. Målet var därför att skapa en modell, som tog hänsyn till konsumentens åsikter, och som modeföretagen kan ha användning för vid utformning av sin virtuella miljö.
Allt flyter ihop : En studie om att underlätta för barn med CVI (hjärnsynskada) att orientera sig i klassrummet
Den här rapporten har tagits fram med stöd av bland annat Specialpedagogiskaskolmyndigheten, SPSM, Resurscenter syn i Stockholm. Ett examensarbete därjag fördjupat mig i rummet som informationsbärare. Målet med studien har varitatt ta fram en gestaltning som baseras på riktlinjer för hur ett moderntgrundskoleklassrum kan utformas för att stödja orienteringen för barn medsyntolkningssvårigheter. Detta för att möjliggöra en ökad tillgänglighet förmålgruppen i den fysiska miljön, vilket i sin tur kan bidra till målgruppenssjälvständighet och trygghet i skolan med förhoppning om ökadkunskapsutveckling. Lärandemiljön i ett klassrum för årskurs två i en avStockholms nyare skolor har studerats för att ta reda på i hur stor utsträckningman idag tar hänsyn till barn med synnedsättning i framtagandet av nya skolor.För att nå målet har jag utgått från teorier och litteratur kring bland annat CVI,perception, orientering/wayfinding, färg och kontrast.
PERFORMING LOLITA : Göra, vara, visa mode och femininitet som motstånd
During the spring of 2014, I have investigated the visual culture of Lolita as practiced in Sweden and Japan. My focus has been on the performative aspect of Lolita. By looking and participating in this colorful subculture, I have met people who are living the Lolita lifestyle on a daily basis as well as former Lolita practitioners. My main concern has been how does one use Lolita.I?ve tried to investigate if it is possible to look at Lolita as being more than just a clothing style.
Ämneshantering hos flerspråkiga med Alzheimers sjukdom
In previous studies there has been indications that multilingualism has a delaying effect of the onset of dementia and damage on cognitive abilities (Bialystok et al., 2007; De Bot & Makoni, 2005, s. 58). Cognitive abilities refers to memory, attention, language, abstract thinking and understandings among other things (Läkemedelsverket). Other studies have seen that individuals with Alzheimer's disease (Swedish abbreviation AS from here on) have difficulties with managing a conversation (Hyltenstam & Stroud 1989). This study aims to describe the topic treatment in bilingual individuals with AS and compare their different languages.
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.

Nonvisual Society
The exclusion of visually impaired from the information flow presented to us through signs was what led me into this project. With a growing amount of information being presented to us on signs and digital information surface the need of communicating this information in a way that could be read by visually impaired is evident. Looking into different ways of communication, my goal was to create something that filled the need of the visually impaired without branding them as disabled. Having a close relative with bad eyesight is became evident on how much it limited her in her everyday life, not being able to navigate herself without the support of her husband. Through interviews with her and others with varying diagnoses I reached an insight in their situation. To my surprise they still favored a visual form of communication before an auditory or tactile form, because it?s easy to survey and quick to interpret.
