Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Varför tycker du inte som mig!? : Livsåskådningars struktur, funktion och immanenta konflikt

This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..

Matematikverkstad : -ett förhållningssätt

SammanfattningDenna uppsats har sin bakgrund i fem ord som kan ses som en kort sammanfattning kring vad matematikundervisningen bör innehålla enligt Lpo94 och kursplanen för matematik. Där står att matematik bör pratas, undersökas, upplevas, skapas och utforskas. Om dessa ord får finnas med i undervisningen så bör man kunna göra matematiken roligare och mer intressant. Att finna glädje och lust till matematiken är väldigt viktigt för att fånga barnens uppmärksamhet och rapporten Lusten att lära?med fokus på matematik diskuterar just vikten av lusten till matematik.  Baserat på vad som står skrivet kring matematikverkstäder så borde pedagoger kunna jobba i enlighet med vad Lpo94 och kursplanen i matematik förespråkar.

Alternativ splicing: en process som medför att flera olika mRNA-transkript bildas från individuella gener

This review article presents the splicing process during messenger RNA maturation and how it is regulated by different Cis-regulatory RNA-sequence elements and splicing factors. A more detailed description of the process alternative splicing and its importance to the function of genes from the model organism Arabidopsis thaliana is also given. A single eukaryotic gene can by the process alternative splicing (AS) give rise to a number of functionally mature mRNA-molecules, which in turn encodes for structurally and/or functionally different proteins. During the course of evolution, the process alternative splicing has thus shown to be effective in increasing transcriptome and proteome diversity of most eukaryotic organisms. This suggests therefore that the dominant theory in molecular biology, a gene encodes for a protein, needs to be corrected.

Arbete med läs- och skrivutveckling i grundskolans tidigare skolår : Två pedagoger berättar om sina arbetssätt

The purpose of this paper is to examine how teachers choose to work with the teaching of reading and writing skills, how teachers justify their choice of teaching method and how the documentation of student development is being used. This paper also discusses the definition of reading and writing, phonological awareness and how different reading- and writing educational methods can be combined. The gathering of information has been done through a literature review in which I have looked at past research on reading and writing. I have also conducted qualitative interviews with teachers involved in literacy learning. The result of my research shows that it is not possible to determine which literacy learning methods that are most effective.

Sunt förnuft : populism i politiska partiers valpropaganda

This study attempts to answer the question of whether the propaganda of the Swedish political parties ?Socialdemokraterna?, and/or ?Sverigedemokraterna?, used for the election to the European parliament 2009, are to be viewed as populistic. Furthermore, is the propaganda to viewed as included in the ?Classical populism?, the ?New populism?, both, or none of the above genres? With a theoretical approach deriving from earlier works on the subject Classical/New populism from a number of writers, the study uses empirical and qualitative text analysis to study the parties propaganda. For each of the two genres of populism an ideal type is set up, which is used to define their core elements.

Konsumtion av försäkringsbeloppet i ansvarsförsäkring : Är skadeståndslagens jämkningsinstitut tillämpliga?

Our digital society encompasses nowadays different channels, which includes social media where many users consider it as a platform where they can fetch news or exchange news and information. This leads to a large spread of news exchange in a very fast speed, which involves the global users within social media to be a part of this social interaction. This study is focused on how Twitter affects the usage of the user?s news consumption. By reaching out to our specific target audience, which includes Twitter users in Sweden, we made a web based survey with a content of relevant questions.

Effektivisering av UI-utveckling i datorspel

This thesis presents my work at the company Fatshark AB in Stockholm. My supervisor Rikard Blomberg, who works as a chief technology officer at Fatshark and is one of the owners of the company, explained that they had experienced weaknesses in the methodology used when developing heads up displays (HUD) for their games. In the latest production, Lead  and Gold, the HUD had been redesigned a number of times, becoming an unnecessarily big expense due to the number of work hours invested. In modern software development, an iterative workflow is commonly encouraged. Despite this fact, the work efficiency could likely be increased by setting up guidelines as a help in the process of developing HUDs and reviewing the solutions.

Utveckling av en ytmonterad fördelningsmätare som underlag för individuell debitering av vattenförbrukning i fastigheter

The master thesis, conducted at Metrima AB, concerns the development of a non-intrusivedistribution meter as a basis for individual tap water billing in apartments.The project is conducted in response to the market interest in individual tap water billing inapartments as an answer to environmental concerns regarding water consumption. Due to thehigh installation cost of traditional water meters, a new method of determining waterconsumption, without having to cut water pipes, is proposed.The proposed method distributes the total water consumption for an apartment complex toindividual apartments according to distribution meters, measuring water run-time, in eachapartment. The water run-time is estimated by measuring the water pipe?s outward vibrationsand temperature changes.A test environment was established and a prototype built, using a tilt- and vibration sensor forvibration sensing and a precision temperature sensor to measure temperature changes. As bothsensors work well in the test environment, further testing was done in 3 apartments for aduration of 5 days.

Reglering av matarsystem vid höghastighetskapning

Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.

Projektrisk : en studie av svenska bygg- och anläggningsföretag

Background: Today businesses are largely structured in projects and temporary organizations. In many companies, the ability to pursue projects is decisive for the business efficiency and competitiveness. The risk literature do not discuss identification and handling ofproject risk in building- and construction companies to a large extent, which has led us to investigate how project risk can be treated and handled in Swedish building- and construction companies. Purpose: The purpose of this thesis is to cover and describe business risk in Swedish building- and construction projects with focus on different risks and risk tools, and also to modify a model for evaluating the business risk maturity. Realization: This thesis has both traces of a case study and a cross-section study and examines eight different companies that are active in the building- and construction business.

Modellering och simulering av det evaporativa bränslesystemet i en personbil

This thesis work has been performed at the department of diagnosis and dependability at Volvo Car Company, Torslanda. The background of this project is based on interest in ascertaining how different factors possibly can affect a diagnosis method, which has been developed to find leaks in the fuel tank and evaporation system. According to the OBD II requirements leaks with an orifice diameter larger or equal to 0,5 mm, must be detected. The idea of the diagnosis method is to create an over pressure in the system with an air-pump. The current through the pump is measured and correlates to the power consumed by the pump.

Vårdpersonalens uppfattningar om fibromyalgi

Aim Our aim is to highlight perceptions of fibromyalgia among health care personell.MethodsA systematic literature review conducted with a deductive approach.FindingsHealth care personell felt insecure because of a lack of understanding which lead to avoiding contact with these patients. Many felt that the fibromyalgia patient was categorised and that they would have been better served with another name of their disease. There was a great distrust against the diagnosis and its aetiology. The patient was perceived as troublesome, illness-fixated and draining the personell of energy. The paradox that the patient is looking so healthy but bearing so much pain was confusing for the health care personell.Conclusions Communication and an empathic encounter was identified as important elements for patient care.
