En effektivare habilitering med stöd av webbaserad utbildning. En studie om habiliteringens utbildningsutveckling
The information technology development that has occurred over the past decade has broughtmajor changes into people?s lives. We have gotten used to being constantly connected to theInternet and always having access to information through mobile technology. This has led tochanges in education and more and more courses have become available through Internet. Theseweb-based educations are nowadays very common in schools and in the business world as theyprovide increased flexibility for the user.Habiliteringen Lundbystrand has seen the potential in this kind of education and believes this isan opportunity for them to rationalize their work by replacing parts of their education for parentswith a web-based education.
Effektivare Askåterföring : Kombimetoden
Undersökningens resultat visar att det finns betydande kostnadsbesparingar att göra vid införandet av en ny metod för askåterföring. Den nya metoden medför betydligt mindre transporter vilket leder till ett reducerat utsläpp av koldioxid och andra ämnen som har en negativ miljöpåverkan.I den nya metoden utnyttjas i viss utsträckning timmerbilarnas lediga kapacitet för transport av aska ut till spridningsområdet vilket då ökar chansen till högre lönsamhet för åkerinäringen..
RENOVERING AV MILJONPROGRAMMET TILL PASSIVHUS : Implementering av tysk prefabteknik
Construction accounts for about 35 percent of the total Swedish energy consumption and most of the energy is used by the large housing stock from the so-called ?Million program?. In the national action plan the government has put forward in energy efficiency. It is mentioned that existing buildings account for more than 90 percent of what is expected to be the housing stock within the coming 50 years. In order to meet environmental objectives its required that the existing stock be reviewed for energy efficiency. The goverment is now initiating a national framework with a budget of SEK 300 million Swedish crowns per year for five years, starting in 2010 to achieve the goal on energy efficient buildings. Energy efficiency of buildings in both new construction and above all within the existing stock are addressed.
Människa ? Teknik ? Organisation ur ett utredningsperspektiv : En intervjustudie av medarbetare vid Statens haverikommission
Human - Technology - Organization (HTO) is a well-established, general unifying concept in the Swedish Accident Investigation Authority (SHK) that represents an approach, knowledge and use of various tools regarding interactions between people, technology and organizational factors. The HTO-perspective is well described in literature but there are few studies on how SHKs staff experiences working according to this method in their investigations. The aim of this study was therefore to describe their HTO-perspective, examine how it is used in the investigations at SHK and describe the investigators experience of working with the HTO-perspective as well as the method's usefulness compared to old methods in accident investigations. A literature study has been conducted in the areas of HTO, Theory of planned behavior (TPB) and safety culture. TPB and safety culture are described in this paper since they highlight the different aspects of a HTO-perspective.

Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
IKT i förskolan : Diskursanalys av två styrdokument och sex förskollärares berättelser om arbetet med IKT
The aim of the study is to learn more about the way preschool teachers work with Information and Communication Technology(ICT). More specifically, this study aims to explore how preschool teachers describe their experience of ICT, the conditions and opportunities to work with ICT, and their own knowledge and competence in the use of digital tools with preschool children. The research method consists of interviews with preschool teachers and observations at five municipal preschools in Stockholm as well as an analysis of the relevant passages in the Curriculum for the Preschool and the Curriculum of Stockholm city. This study shows that there seems to be great variation in the amount of ICT tools present in preschools. Preschool teachers expect a lot from ICT, and the improvements that it can make on their work.
Taxonomianalys av läroböcker i geografi för årskurserna sju till nio
The purpose of this thesis is to investigate the democratization process in Kurdistan on the basis of consolidation democracy with focus on arenas defined by Linz and Stepan (1997), namely economic, political, legal, civil society and arenas of state bureaucracy. Furthermore, I intend to explain Kurdistan?s road toward democratization in Kurdistan from 1991 until today, with a focus on the years 2003-2012. The main results are that Kurdistan has developed conditions that support a future consolidation of democracy. However, there are weaknesses in the economic situation, rule of law and the arena of bureaucracy.
Utveckling av tjänster för ett mobilt medium
The mobile revolution is here to stay, and today most people have (at least) one cell phone at home. Some even a PDA (Personal Digital Assistant)as a complement for the simpler tasks at the office, e.g sending e-mail, word processing, browsing the Internet etc. Many business have also given the employees the opportunity to do some of the business tasks inbetweeen customer visits with the help from a cell phone or PDA.Despite all this, the so called Internet connected mobile revolution is often mentioned as a big failure. Maybe because the people in general tended not to use the new technology as much as the companies predicted. This could be because they still haven't learned how it works, or just don't seem to have the need for services provided.After a couple of failures in the development process, almost every cell phone has support for mobile Internet today.
Anläggningsmätning
This report aims at giving you as a reader a basic knowledge in measurement techniques used in the road/land construction and witch instrument and methods that is commonly used. It also tries to shed light on the problem with unfinished or incomplete blueprints, which cause additional work performed by the surveyor. This report is written in collaboration with PEAB Umeå whom has given insight in their work.The goal of this report is to examine what kind of work surveyors has to perform on blueprints delivered by a technical consultant. The reader of this report gets a run-through of the different theoretical measurement techniques used today and a short explanation of different measuring instruments used by surveyors in their day to day work. Computer programs used in the field of construction are briefly explained, and some of the most common file extensions used, for example dwg and Land-xml.The report concludes in a questionnaire that was sent out to surveyors employed by PEAB.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Nyutvecklad lastsäkringsutrustning för järnvägsvagnar: ökad effektivitet och minskade godsskador
Problemformulering: Järnvägstransporter av gods har på senare år tappat storamarknadsandelar till vägtransporterna. Orsakerna är många, enav dem kan konkretiseras till en betydande envägstrafik vilketär en direkt följd av dålig lastsäkringsutrustning i vagnarna.Målsättning: Målet med projektet är att utveckla ett koncept för ny typ avlastsäkringsutrustning som kan integreras till befintligvagnpark. Utrustningen ska alltid finnas i vagnen och hamöjlighet att lastsäkra flera typer av produktflöden menframförallt palleterat gods.Förutom grundläggande krav på hållfasthet för de krafter somuppkommer vid rangering och transport ska utrustningensamtidigt vara så liten som möjligt både vad gäller vikt ochvolym.Metod: Projektet är i grunden en produktutveckling vilken består av enstegvis utarbetad modell av Ulrich och Eppinger när välproblemet hade identifierats. Dessförinnan krävdes dock ennormativ studie för att klargöra de problem som åligger ochsom behöver lösning. Informationsinsamlingen har framföralltbestått av kvalitativ data av både primär och sekundär karaktär.Slutsatser: Författarna anser att en förändring i dagens konservativabransch är önskvärd för att stärka järnvägens konkurrenskraft.Integrering av författarnas lastsäkringsutrustning skulleinnebära en stärkt marknadsposition för järnvägens roll somgodstransportör.
Är avståndet för transport av spannmål en kritisk faktor i framställningen av etanol till framtidens bränsle?
Förr eller senare minskar tillgången på råolja och därmed bensin och diesel i världen. Då måste vi människor finna andra drivmedel för att klara våra transportbehov och andra behov som är beroende av drivmedel. Förutom detta finns det behov av åtgärder som minskar emissioner av CO2 till atmosfären. Etanol som drivmedel är relativt nytt, och marknaden är potentiellt mycket stor. Agroetanol AB är en etanolfabrik i Norrköping som använder spannmål som råmaterial.
