OneCore

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

Dokumentationssystem för fjärrvärmenät

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

Torkad eller gastät lagrad spannmål till värphöns : en fallstudie

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

Environment simulation of track-based systems

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

Automatiserad kalibrering av väderradar

För att kalibrera väderradarna i Sverige finns en miniräknare med program som styr kalibreringen. Deluppgiften ?Program för kalibrering? innebär att överföra dessa program till en PC. Då ingen dokumentation finns om hur kommunikationen sker mellan radar och miniräknare, är första steget att analysera och jämföra programkoden från miniräknaren med informationen från en linjelyssnare. Därefter skrivs programmen i det grafiska programmeringsspråket Agilent Vee.

Gräfsnäs dolda skatter

This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.

Representativa testnät försvenska eldistributionsnät

This project was started within the Market-Design programme of Elforsk, with the aim of developing representative test systems of Swedish distribution networks. Using such test systems as a basis for reliability and customer interruption cost calculations makes it feasible to analyse the network tariff regulation of Swedish power  istribution companies. In particular, it enables studies of the incentives for companies to invest in system reliability. Until now, the available test systems are either not representative of Swedish conditions, or too small in scale and limited in function.Within this project we have created two test systems. In order to represent the diversity of actual Swedish distribution networks, we have created one test system for urban environments and another for rural environments.

Byggplatsnät : Att etablera ett spänningsfritt stomnät

Geodata finns idag tillgängligt via geodataportaler runt om i världen. På dessa geodataportaler beskrivs datamängder och tjänster som kommer från olika myndigheter. Geodatasamverkan har uttryckt intresse för att kunna beskriva realtidsresurser på dessa portaler med hjälp av metadata. Utifrån ett samarbete mellan SMHI och Lantmäteriet har denna studie tagits fram där en dynamisk realtidsresurs från SMHI testas beskrivas med Geodataportalens nuvarande struktur. Befintlig litteratur har undersökts för att presentera en bakgrund.

Trådlös, beröringsfri temperatursensor med insamlingssystem: Förbättring/vidareutveckling av prototyp

Mitt uppdrag var att undersöka om det fanns potential att förbättra en befintlig prototyp som Actegra AB hade utvecklat. Prototypen är ett system för att övervaka delar i konstruktioner, t.ex. takstolar, broar med mera. Detta sker genom avläsning av en rad trådlösa givare som sedan skickar data till en gateway som är ansluten till Internet. Gatewayen har i sin tur en websida där användaren enkelt kan läsa av datat via dator eller t.ex.

Maskinen ska kunna skära i mjuka material som trä, plaster men även mjukare aluminium.Resultatet är en tre axlig cnc- router som drivs av tre stycken stepmotorer som är kopplade till respektive kulskruv. Cnc routern har ett arbetsrum på cirka 600x450x150mm.

Ekonomistyrningens påverkan på MRP-implementering: en fallstudie av ASSA AB

The implementation of a material requirements planning system is a complex and demanding task. There has been much research into what factors are important in such implementations, but seemingly very little about the links between critical success factors and management control systems. This thesis attempts, through a case study, to answer the question of how management control systems affect the implementation of an MRP system in ASSA AB, a Swedish manufacturing firm. Data is primarily collected through interviews. Theory regarding implementation success definitions, critical success factors as well as management control systems is presented.

Homosexualitet i tre klassifikationssystem under tre decennier: Ett queerteoretiskt perspektiv på SAB, UDK och DDC.

The aim of this masters thesis is to, from a queertheoretical point of view, examine the possibilities to classify the subject homosexuality in three different classification systems. The three systems that have been analysed is the Swedish classification system SAB, the Universal Decimal Classification UDC and Dewey Decimal Classification DDC. The analysed editions are updates from the beginning of the 1970´s until today. The emphasis has been on how well the systems correspond to the changing society. We found several differences between the three systems, but also some resemblances.

Implementering av radarextraktor med DSP

Den här rapporten beskriver hur en radarextraktor kan implementeras med hjälp av en signalprocessor (DSP). En radarextraktor extraherar viktig information ur en radarvideosignal och skapar plottar. En plott anger bäring och avstånd till ett mål, t.ex. ett fartyg eller ett flygplan. Plottarna levereras vanligtvis till en målföljare.
