Ella Matematik - Internetbaserat läromedel för grundskolans matematikundervisning
Ella Mathematics is a web portal that will completely replace the printed math text book in the Swedish elementary school. When the math education is moved in to the digital world the flexibility and adaptability will increase.In 2011 the Swedish government revised the Swedish school system, which contained a whole new curriculum for the elementary school math education. This has been the foundation for the development of Ella Mathematics and the design of the three different users; student, teacher and parent. The development has been done with Dynamic Product Development methods from the project start in September 2011 until the final exam in May 2012.Ella Mathematics has been developed with the pupil?s math knowledge in focus.
Tillbakablickande nationalism ett minne blott? En teorikritisk fallstudie om nationalism och identitet i Hong Kong
In this thesis I have criticized traditional nationalism theories formulated by Eric Hobsbawm, Ernest Gellner, Benedict Anderson and Anthony D. Smith. The critique has been based on my belief that nationalism theories do not explain nations whose foundation is built on forward-looking, dynamic aspects such as economy, human and civil rights, and democracy. Traditional nationalism theories have been focused on historicizing perspectives whereas I want to draw attention to non-historicizing perspectives within the field of research. So far nationalism theories has had a shared past or a shared ethnicity as its focal point.
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
Mälarens vattennivå i ett framtida klimat
The discharge from Lake Mälaren is regulated to keep the lake water level within limits set by a water decree. Despite this, in the year 2000 the lake water level rose above the upper limit. Studies conducted at the climate modeling unit Rossby Centre at the Swedish Meteorological and Hydrological Institute (SMHI) indicate that the inflow to the lake may increase in the future. A flood in the area will, among other things, strike infrastructure and residential districts.The aim of this study was to investigate the water levels of Lake Mälaren in future climates. In addition to this possible future expansion of the lake discharge though the sluice gates in order to keep water levels below limits set by the water decree and to prevent flooding of the shoreline were discussed.
Skadedjursbegränsare i horisontella avloppsrör
The purpose with this project was to invent a product that secures buildings sewersystems against rats. The problem was presented to us by a local building maintainer inHalmstad, who had experienced big problems with rats in his real estate. The project hasbeen carried out by Per Johansson, Robert Lidén and Niclas Nilsson under our ownauspices. We are primarily sponsored by AMLI Business Partner but also byInnvationsgruppen, Halmstad Fastighets AB and Anticimex.To be able to secure a whole building with only one product we came to the conclusionthat the product must be placed in the horizontal sewer pipe that connects with themunicipal sewer system. Our goal was to invent a product that prevent rats from passingand at the same time not affect the water flow.
BIM Building Information Model : Hinder & Drivkraft
The construction industry is a costly business such in respect of capital for most construction defects which then require rework, tear down and rebuild again. This study is meaningful awareness of tools that can reduce this best through communication and information sharing between the parties. The construction industry is known as temporary projects organizations, where the construction project consists of several actors who have to communicate and share information between them to avoid mistakes later in the build time. These actors are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to create a routine for the association and the shattering of these actors. To implement such behavior using a tool such as BIM in the industry whose size perhaps is indescribable may be a very hard task. BIM (Building Information Model) could be seen as the solution to this problem because it acts as a portal where the actors involved must sign in and communicate, share information, and eventually create a behavior, a routine for this association and division of the actors following the end of the project. The technology could help the involved from the beginning of the project, already in the model stage, break down and prevent any construction barriers when the building has been placed in the works.
Att leva är att känna - en pilotstudie i affektfokuserad terapi för unga vuxna
Varumärken inom B2B börjar få allt större uppmärksamhet bland forskare och företag i takt med att det uppmärksammats att varumärken har betydelse inom B2B-kontexter. Varumärket är ett av få sätt att differentiera sig på konkurrensintensiva marknader och kan medföra fördelar som en ökad kundlojalitet, premiumpriser och en ökad möjlighet att nå nya marknader. Samtidigt är forskningen om hur företag inom B2B bygger varumärken begränsad. B2B-marknader kännetecknas inte av produkterna utan av köparna som inte uteslutande är vinstrivande företag utan även kommuner, institutioner och icke- vinstrivande organisationer.I följande studie studeras underleverantörer vilka kännetecknas av dess förmåga att producera varor och tjänster till förmån för en köpare och dennes specifikationer. För en underleverantör är den grundläggande rollen att vara en värdeförmedlare som underlättar kundernas värdeskapande.
Realistisk integrering av 3D i en verklig miljö
Det kommande innehållet i detta examensarbete kommer att handla om min frågeställning som berör integrering av 3D objekt i en verklig miljö: ?Vad finns det för metoder att integrera 3D objekt med en verklig miljö och hur gör man??.Arbetet och efterforskningen har utförts i Söderhamn, där jag har arbetet hos 3D animationsföretaget Magoo 3D Studios. Med hjälp av anställda på Magoo har jag genomfört experiment för att själv prova på de olika metoder som ska kunna besvara min frågeställning.Som resultat så har jag kommit fram till att alla divisioner inom 3D, som modellering, texturering, ljussättning och compositing kan bidra till realistisk integrering på sitt eget vis, dock i olika utsträckningar. Mina experiment har alla varit lyckade och jag känner att de är på rätt väg mot fotorealistiska resultat.I slutändan så upplever jag att de metoder som bidrar mest till en realistisk integrering är en bra ljussättning med en Image Based Lighting metod, samt att ha bra vetskap om hur en kamera fungerar för att sedan kunna efterlikna dess typiska drag samt artefakter så bra som möjligt.Kombinerar man dessa metoder så är man en bra bit in på vägen till fotorealism där man inte längre är säker på om datorgenererade bilder är riktiga eller inte..

Observatörer för skattning av verktygspositionen hos en industrirobot : Design, simulering och experimentell verifiering
This thesis approaches the problem of estimating the arm angles of an industrial robot with flexibilities in joints and links. Due to cost-cutting efforts in the industrial robots industry, weaker components and more cost-effective structures have been introduced which in turn has led to problems with flexibilities, nonlinearities and friction. In order to handle these challenging dynamic problems and achieve high accuracy this study introduces state observers to estimate the tool position.The observers use measurements of the motor angles and an accelerometer and the different evaluated observers are based on an Extended Kalman Filter and a deterministic variant. They have been evaluated in experiments on an industrial robot with two degrees of freedom. The experimental verification shows that the state estimates can be highly accurate for medium frequency motions, ranging from 3-30Hz.
Att tänka annorlunda : Samtidens dynamiska lärandemiljöer utgår från ett förändrat sätt att tänka och förstå ledarskap
Studien syftade till att undersöka och belysa hur FM:s ledarskap uppfattar och beskriver FM:s lärandemiljö och samtida utmaningar. Studien avsåg även att genom sina fynd, visa på indikativa linjer kring hur ett ledarskap som främjar lärandemiljön och möter samtidens utmaningar kan förstås. Det empiriska underlaget bestod av en enkätundersökning där 55 officerare med mångårig ledarerfarenhet inom FM deltog. Dessa var indelade i två grupper. Studien hade en tvärvetenskap-lig metodologisk ansats och omfattade både kvantitativa och kvalitativa analysmetoder.
Adaptiv stämning : En bedömning av acceptabilitet och tonkvalitetsuppfattning
This thesis presents an adaptive tuning system that can be described as a dynamic Just Intonation tuning system, being compatible with equally tempered instruments. The tuning system is called Hermode Tuning (HMT) and the tuning used as comparison for evaluation is the standardized western tuning, the equal tempered tuning. This study investigates preferences for these two musical tuning systems, depending on whether the tunings are presented on a piano or with woodwind instruments. A listening test was done with students at the Falun Conservatory of Music, including both a vertical listening (intervalls) and a horizontal listening (cadenses and musical compositions) of Hermode tuned musical material. Overall the results showed no significant preferences for either tuning system irrespectively of what instrument it was presented with.
Konstruktion och utprövning av datorbaserat test för intonation och rytm : Icke-språklig Testning Av Prosodi - ITAP
Generally prosody is described as the rhythmic, dynamic and melodic features of language. Prosody is further often described as suprasegmental, since its properties go beyond vowels and consonants, which are segmental characteristics of language. A relationship between prosody and music has been noticed and described for several decades. At present, there are several studies proving relationship between prosodic and musical abilities. The aim of the present study was to construct a test for prosodic non-linguistic perception and production regarding intonation and rhythm. The test was tried out on 16 children with typical language development aged 4;6-7;6 years. Before testing of ITAP each participant were asked about musical experience.

Elektronisk mobbning: ur ett professionellt perspektiv
The purpose of this study was to examine how professional workers understand the bullying problem among Swedish youth in the age of 13-15 years. The main focus was to examine the new phenomena electronic bullying, from a professional point of view.The biggest question to answer was: "How does the school and organizations understand the bullying situation among Swedish youth today?" Individual interviews with professional social workers within the school and nationwide organizations have been used to fulfill the purpose of this work. Two different respondent types were used in order to get a wide perspective and a dynamic view.Electronic bullying had increased, but the school yard was still the most common arena for bullying, according to the respondents. The schools tried to prevent bullying, but the social workers felt that they lacked some knowledge of electronic bullying, because it was relative new.
