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.

MÀtsystem 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.

EnergiomstÀllningens konflikter : en studie av bergvÀrmetrenden i Uppsala 2010-2011

Den hĂ€r studien beskriver en konflikt kring en bergvĂ€rmetrend för bostadsrĂ€ttsföreningar som uppstĂ„tt i Uppsala under hösten 2010 och vĂ„ren 2011. Konfliktens parter Ă€r Ă„ ena sidan bostadsrĂ€ttsföreningar som valt att satsa pĂ„ bergvĂ€rme för att i första hand minska sina uppvĂ€rmningskostnader frĂ„n fjĂ€rrvĂ€rmen. Å andra sidan majoriteten i Uppsala kommuns miljö- och hĂ€lsoskyddsnĂ€mnd som Ă€r oroliga för trendens miljömĂ€ssiga effekter, framförallt för elförsörjningen, och föresprĂ„kar fjĂ€rrvĂ€rme. UtifrĂ„n tvĂ„ teoretiska perspektiv har jag satt konflikten kring bergvĂ€rmetrenden i ett större historiskt och samhĂ€lleligt sammanhang. Jag har prövat möjligheten att se konflikten som en konflikt kring fjĂ€rrvĂ€rme som ett stort tekniskt system med referens till teknikhistorikern Thomas B. Hughes.

Interacting with EDIT. A Qualitative Study on, and a Re-design of, an Educational Technology System

This thesis aimed to study the interaction between an educational technology system and its users and give suggestions for design improvements. 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.

En förstudie till kvalitetsutveckling pÄ 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: förhÄllandet mellan epistemologi och bibliografisk klassifikation analyserat utifrÄn 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 energianvÀndningen 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 underhÄll

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.

Modularitet och objektorientering : Byggandet av ett program som kan visa en molekyl

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

Customer Relationship Management : en studie om CRM-system ur ett traditionellt samt molnbaserat perspektiv

CRM-system har visat sig vara ett allt mer vanligt och effektivt marknadsföringsverktyg. Ett CRM-system hjÀlper ett företag att strukturera samtliga kunder samt information om kunderna pÄ ett stÀlle. MÄlet med ett CRM-system Àr att förstÄ kundens behov och dess vÀrde för företaget.Studiens syfte Àr att beskriva CRM och hur ett sÄdant system kan anvÀndas. Vi har valt att undersöka leverantörers och kunders syn pÄ CRM-system, vilka för- och nackdelar de ser med ett CRM-system. Vi har Àven valt att belysa vÀsentliga skillnader mellan traditionella CRM-system och sÄ kallade molnbaserade CRM-system, nÄgot som har blivit allt mer vanligt.

Lathunden ? för dig som vill göra rÀtt frÄn början : Ett arbete om att öka förstÄelsen för ett nytt CMS-system genom teknisk kommunikation.

Syftet med mitt examensarbete var att undersöka vilka faktorer som gör teknisk kommunikation tillgÀnglig och lÀttförstÄelig. Det skulle leda fram till en lÀsvÀrd lathund för anvÀndare av ett nytt CMS-system. Arbetet har genomförts i samarbete med Telia, som Àr inne i ett förÀndringsarbete gÀllande sina informationssystem. De ska införa ett nytt sÄ kallat PIM-system (Product Information Management), som ska innefatta ovan nÀmnda CMS-system och kommer innebÀra ett förÀndrat arbetssÀtt och nya arbetsuppgifter för min berörda mÄlgrupp. För att lösa problemet har jag tagit hjÀlp av en fokusgrupp och gjort en webbenkÀt. Jag har stÀllt mig frÄgor om vad teknisk kommunikation kan bidra med vid framtagning av ett instruerande material, samt i vilka syften anvÀndarna kan tÀnkas lÀsa den typen av material. Med hjÀlp av teorier och ovanstÄende metoder producerade jag ett förslag pÄ hur lathunden kan se ut. Jag testade ocksÄ förslaget pÄ mÄlgruppen för att fÄ deras Äsikter, i syfte att förbÀttra slutresultatet..

KartlÀggning av informationsbehov

This report is the result of a thesis carried out during the spring of 2010 at Sandvik Coromant in Gimo. The purpose of this thesis has been to make an inventory and mapping of information used by flow groups that are most relevant for the day-to-day work. This mapping will then form the basis for information supplied by an automated system.The project consisted of:Identifying how the information is supplied today.Inquiring into the needs of an automated system.Which needs of information that will be provided by the system.Data collection occurred in two ways, both through observations and interviews. Observations of the participants were carried out early in the thesis, where the aim was to create a picture of the problem, and gradually develop a basis for the actual interview study. At each observation, an unstructured observation was used, which means that all activity was recorded.

Metoder vid implementation av affÀrssystem : en studie om anpassning

Dagens företag Àr i stort behov av information. Företag som har mÄnga avdelningar behöver möjligheter för att enkelt och smidigt kunna samordna information för hela företaget. AffÀrssystem erbjuder denna möjlighet genom en modulbaserad konstruktion som integrerar ett företags samtliga avdelningar i ett enda system. Problem kan dock uppstÄ dÄ ett valt affÀrssystem inte passar företagets verksamhet. En kompromiss mellan system och verksamhet mÄste dÄ försöka uppnÄs.Ett affÀrssystem implementeras ofta i samband med en metod, vilken ger detaljerade beskrivningar för hur implementeringen ska gÄ till.

PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.
