Rummets betydelse för kunskapsproduktion ? en tolkning av Lunds stadsbiblioteks funktioner i ljuset av dess arkitektur

This paper aims to apply a specific architectural theory onto Lund City Library in order to achieve a better understanding of how the physical concept of the library is affecting our knowledge and our production of meaning; and furthermore how it suggests a certain form of usage. This paper discusses the ways in which architecture is affecting us when we use the library. The paper attempts to answer the following question: ? Which one of Koch?s spatial structures could apply to Lund City Library, and in which ways could this spatial structure be a producer of meaning? The specific architectonical theory used is developed by Daniel Koch in his paper Spatial Systems as Producers of Meaning: the Idea of Knowledge in Three Public Libraries. This theory is the method of the paper as well.

Generellt mät- och styrsystem

Examensarbetets syfte var att skapa ett generellt mät- och styrsystem som är möjligt att fjärrstyra över Internet. Systemet består av en kontrolldator och ett antal separata moduler, vilka var och en realiserar någon typ av mät- eller styrfunktion. Användningsområdet för ett sådant system är brett; det kan exempelvis användas inom automation av bostäder, för process-övervakning och styrning inom tillverkningsindustrin, eller inom under-hållningsbranschen.Eftersom ett fullt utbyggt system kan bestå av ett drygt 100-tal olika mo-duler, är det här examensarbetet av praktiska skäl begränsat till att rea-lisera en handfull av dessa. Då systemet är enkelt att skala upp, är den be-gränsningen i antalet realiserade moduler i prototypsystemet inget som påverkar de erhållna resultaten. Exempel på storheter som kan övervakas är temperatur, avstånd, lufttryck och ljusstyrka.

UML i teori och praktik

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

Stubbtransporter och bränslekvalitet hos stubbved :

Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

Betesdrift vid automatisk mjölkning i ekologisk produktion :

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

Mätsystem för effektförluster i en högfrekvenstransformator

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

TOMO Hugglink

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Bärare av mat : Arbetsfördelning och könsskillnader i restaurangbranschen utifrån ett genusperspektiv

The distribution of work related tasks depending on gender leads to different appraisal depending on which gender is performing a task. This aim of this research is to study how gender differences influence task allocation within the restaurant industry. The study is inspired by a discourse analysis perspective complemented by constructivist and critical pragmatic theory. Interviews were conducted in two focus groups with seven participants in total. The analysis is divided into four sections which answer six discourse analytical questions using the interview material.

En experimentell studie av vulkaniseringstidens och vulkaniseringshastighetens påverkan av värmeväxlarpackningar

A two-factor design of experiments done on GGAB for the identification of two selected factors influence on the length of the scattering of heat exchanger gaskets. The work consists of four parts: study, choice of survey method, the performance of investigation and analysis of the results. Chosen factors on the study are considered to be the most effecting of the length distribution of seals during the production of GGAB. The study is the first of its kind both in GGAB and in the rubber industry and has an experimental nature..

Energiomställningens konflikter : en studie av bergvärmetrenden i Uppsala 2010-2011

Den här studien beskriver en konflikt kring en bergvärmetrend för bostadsrättsföreningar som uppstått i Uppsala under hösten 2010 och våren 2011. Konfliktens parter är å ena sidan bostadsrättsföreningar som valt att satsa på bergvärme för att i första hand minska sina uppvärmningskostnader från fjärrvärmen. Å andra sidan majoriteten i Uppsala kommuns miljö- och hälsoskyddsnämnd som är oroliga för trendens miljömässiga effekter, framförallt för elförsörjningen, och förespråkar fjärrvärme. Utifrån två teoretiska perspektiv har jag satt konflikten kring bergvärmetrenden i ett större historiskt och samhälleligt sammanhang. Jag har prövat möjligheten att se konflikten som en konflikt kring fjärrvärme som ett stort tekniskt system med referens till teknikhistorikern Thomas B. Hughes.

The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

En förstudie till kvalitetsutveckling på GD-tryck

The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system.

Anarkistisk klassifikation: förhållandet mellan epistemologi och bibliografisk klassifikation analyserat utifrån Paul Feyerabends anarkistiska teori

The aim of this master?s thesis is to investigate how Paul Feyerabend?s anarchistic theory of knowledge can help our understanding of bibliographical classification and to analyse how epistemological assumptions are manifested in bibliographic classification. Paul Feyerabend?s anarchistic theory of knowledge and science is the theoretical approach of this thesis. The first part of the thesis consists of an introduction to bibliographical classification and epistemology.

Effektivisering av energianvändningen i en förskola

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Klassificering av processutrustning - en grund för riskbaserat underhåll

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.
