Energikloka hus i Järinge - energiteknisk uppföljning
Energy-wise houses in Järinge - technical follow-up The company JM built energy-efficient houses in Tensta in Stockholm. They have built a total of 16 houses divided into two parts of A-houses and B-houses. The buildings are an attempt by JM to minimize energy-use of the buildings without affecting the comfort and living standards. The project aims to examine the data for the 16 houses on the basis of data and produce a report showing how the buildings worked through a technical perspective. JM approximates that the purchased energy will not be higher than 95 kWh/m2 per year.
Utveckling och konstruktion av dämpare och låssystem för vågkraftverk
The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
Störningar inom kontrollzon
This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.
Kartläggning och visualisering av riggkonstruktionsprocessen : Fallstudie från Scania
Mapping a process enables a greater understanding of the work, and is standard to evaluate and improve a process. This thesis is conducted at Test Bed Mechanical Design at Scania in Södertälje. Test Bed Construction is a complex process, characterized by a large amount of creative work, technical challenges and coordination between different people and different organizational functions.The aim of the thesis was to identify the Test Bed Construction Process and to develop a visual model of the workflow that also served as support for the engineers in their daily work. During the mapping process, comparisons were made with previous research in lean product development to identify process improvement.A literature review on process mapping and process visualisation resulted in a method for process mapping. The study showed that research on process visualisation is neither structured nor well defined.
Reklambyråer & Samhällsansvar : en studie av reklambyråers förutsättningar för ett socialt ansvarstagande
Background: Research results show that the potential of corporate social responsibility (CSR) has increased. That means there is a growing pressure on Swedish companies to act with responsibility: general public has a positive attitude towards companies that communicate their CSR. Advertising agencies have been criticized by their way to manage the question of social responsibility. One of the characteristics of an advertising agency is their anonymity; even though their products are extremely visible, it is rarely clear who gave rise to an advertising production. If this is put in relation to CSR in general, we find ourselves in a contradictory situation when CSR in many cases is about exposure of the responsible corporation.
Produktivitet och lönsamhet vid skogsbränsleuttag längs skogsbilvägar :
With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.
Högskolebibliotekens användarorientering: En studie i hur de nya, medelstora svenska högskolebiblioteken har utvecklat sin användarorientering, från högskolereformens införande 1977 fram till idag.
The aim of this master thesis is to describe some general trends and important steps in the Swedish university libraries user-orientation from the implementation of the university college reform 1977 until today. The aim gave rise to four further questions. Literature studies and empirical studies in the form of focusing interviews have been carried out, in order to answer the questions. Of the entire background material I have made a simple form of general analysis. I found that the libraries, during the years have interacted with the following four interested parties, the government, the mother organization, other libraries and the library users.
Läsförmågans faktorer och deras bidrag till läsning : En jämförelse mellan barn med olika nivå av läsförmåga, utifrån The Simple View of Reading
The simple view of reading is a theory in which reading is divided into decoding and linguistic comprehension. The theory has been used to explain and to subgroup reading disabilities. Research has also investigated if additional factors are of relevance to reading. In the present study, decoding was divided into the factors orthographic decoding and phonological decoding, while comprehension was divided into word comprehension and grammatical comprehension. The purpose was to analyze these factors and their contribution to reading ability in children in fourth grade: one group with reading difficulties (n=36) and one group with typical reading ability (n=36).
Matvanor och attityder hos högskolestudenter i förhållande till livsmedelsverkets kostråd
The study was a quantitative cross-sectional study which aimed at investigating college students? eating habits in relation to the Swedish food agency dietary recommendations. The likely factors associated with eating habits and attitudes towards dietary recommendations were also investigated. Non probability sampling method was used giving rise to convinient study sample of 51 individuals (41 women and 11 men) ages 19 to 37. The participants were part of four different types of educations, Care and health, Economy, Engineering, computering and societal planning and Culture and media.
Upplevelser av osäkerhet: En kvalitativ studie av globaliseringens effekter för ungas etablering på arbetsmarknad och familjebildning
Globalization is described as processes of economic, social and political character and a tendency in the field has been to study these aspects of the phenomenon separately. Another common feature of previous studies is to relate to the field at a high abstraction level and talk about the effects and changes in general terms. Such studies of quantitative and statistical nature in which people are constituted as homogeneous groups hides the fact that the relationship between social attributes and context creates unique positions where the effects of globalization are diverse (Sprague, 2005, pp. 16 - 18). The purpose of this bachelor thesis is therefore to break with this entrance to the field and instead focus on a micro level perspective.By conducting a qualitative interview study guided by the globalization theory of the Globalife research team, which shows how structures at the macro level can be understood to affect the micro level, the aim is to reveal potential knowledge gaps within the field.
Extubation av nyopererade patienter? : En randomiserad kontrollerad klinisk pilotstudie vid Centrala intensivvårdsavdelningen på Uppsala Akademiska sjukhus?
Syfte: Studiens syfte var att jämföra en ny extubationsalgoritm med sedvanligtextubationsförfarande. Gruppen som studerades var patienter som genomgått en HIPEC-operationoch vårdats på Centrala intensivvårdsavdelningen.Metod: I En randomiserad kontrollerad klinisk pilotstudie randomiserades patienterna till en av tvågrupper. Därefter extuberades patienten enligt en studiealgoritm eller post-operativ standard.Resultat: Syresättningen var väsentligen oförändrad för studiegruppen (37,5 kPa till 36,6 kPa)medan den sjönk för kontrollgruppen (50,1 kPa till 40,6 kPa) vid jämförelse mellan 10 minuter efterankomst och 15 minuter efter extubation. Efter 13 till 18 timmars kontroll strax innan patienternalämnade intensivvårdsavdelningen var syresättningen på samma nivå som 15 minuter efterextubation för både studiegruppen och kontrollgrupp. Således kvarstod en försämrad syresättninghos kontrollgruppen vid utskrivning jämfört med 10 minuter efter ankomst.Slutsats: Studien visar att det skulle kunna vara fördelaktigt att extubera patienter enligt denstudiealgoritm som testats jämfört med dagens kliniska standard.
säkerhet inom 3G
Problem: Idag har de flesta detaljhandelsföretag någon form av kundklubb för att stärka banden mellan sig och sina kunder. Men skapar kundklubbar lojala kunder per automatik, eller krävs det mer än vad de flesta företag erbjuder idag? IKEA Family är en av de kundklubbar som funnits längst och på varuhuset i Älmhult upplever man inte att potentialen med kundklubben utnyttjas fullt ut då relationerna med medlemmarna inte utvecklas i önskvärd utsträckning. I detta arbete undersöks huruvida detta beror på konceptuella brister, val av strategi eller implementeringen av konceptet på varuhusnivå eller om det finns andra förklaringar. Syfte: Syftet med uppsatsen är att utifrån vår fallstudie på IKEA-varuhuset i Älmhult, samt med hjälp av utvalda teorier kring lojalitet, relationsmarknadsföring och strategi, skapa förståelse för hur en kundklubbsstrategi bör utformas och förverkligas samt visa på vilka problem som kan uppstå.
Företrädaransvar enligt SFL
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Skriftspråksskillnader? : En jämförande studie av flickor och pojkars skriftspråk på gymnasienivå
Our society has faced monumental changes and therefore our working life has changed as well. We are now in the twentieth first century and still our labor market is gender-segregated. Today networking is an important part of working life and one cannot emphasize enough the importance of having good connections in your network. Networking is now seen as an important tool when it comes to your career. In the past networking has been the men?s arena and it has almost been seen as a male institution.
