Övervakning för DC-system

Examensarbete har utförts för AIAB DC Systems i Karlstad.Vår uppgift gick ut på att göra ett övervakningssystem för DC-system. Enheten skall användas för att övervaka isolerade DC-system avseende spänningsnivåer och isolation samt larma vid fel. Tidigare har man haft ett analogt system ute på marknaden men nu vill man ha ett digitalt processorbaserat system.Vi har använt oss av en 8-bitars RISC-processor. Programmeringen har gjorts i assembler med hjälp av ett utvecklings-kit och sköter logiken för övervakningen. Programmet manövreras med två tryckknappar och en display.Programmet vi har tagit fram behöver kompletteras med vissa funktioner.

The company that wanted this system is called Orbit One and is located in Ronneby, Sweden. They have had a problem with old documents circulating in different versions and in different binders. Now thanks to their new system they can access their documents easy and on demand through their intranet..

Humanurin till åkermark och grönytor : avsättning och organisation i Göteborgsområdet

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

Systemutveckling med avseende på systemförvaltning

This final year project is dedicated to investigate the problem domain of system maintenance management. The purpose is to find problems in the system maintenance management of today. Whether there is any problem that can be elicitated in the requirements engineering?s phase that could help to obtain more maintenance management friendly systems and if it is not possible to obtain more maintenance management friendly, what else can be done?It has been learned that there are many problems today in the problem domain and the most great ones are the system documentation, stress and a systemknowledge lack among developers, system managers and system users.The requirements that have been found for this problem is good documentation, and use of simple solutions in the creating of the system..

IT-systemsutvärdering för konsultverksamheter Vid val av nytt system att sälja

Konsultverksamheter har idag en stor mängd system och leverantörer att välja mellan vid val av att bli återförsäljare till ett nytt system. Denna mängd av system kan vid vissa tillfällen ställa till osäkerhet i form av vilket system som passar bäst in i verksamhetens portfolio. Genom en effektiv utvärdering kan dock detta avhjälpas och det system som passar bäst för verksamhet väljas. Uppsatsen bygger på en kvalitativ litteraturstudie där också en intervju utförts. Vidare har de teoretiska utgångspunkterna hämtats utifrån modeller såsom Standardsystem i Verksamheter och Välja och Förvalta Standardsystem. Dessa modeller ligger sedermera till grund för den modell som presenteras i uppsatsen och förenklar konsultverksamheternas problematik med att fatta ett genomarbetat val av system till sin portfolio..

Systemutveckling i praktiken : konsten att tillmötesgå den okända användarens krav

ABSTRACT System development has become more and more concentrated on development for the Web and this has resulted in larger target groups. It will most surely continue to be so considering that the Web will be the infrastructure of business and services in the future. A big target group involves that the owner of a system can earn a lot of money from the paying users, but that assumes that the system can meet user needs. If a system on the Web does not satisfy the user?s demands then they will use the competitor?s system instead because it is only a mouse-click away.

Övertoner i elnät vid Skellefteå lasarett : Harmonics in power grids at Skellefteå Hospital

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

Bevarande av och tillgänglighet till samlingar : exempel från Västerbottens museums textilsamling

This thesis is performed as a case study in Västerbotten Museum's textile storage space. The intention with this study is to investigate the relationships between the museum?s tasks: to collect, preserve and make the collections accessible. The aim is to reveal the problems that exist in museums today with increasing collections, less resources for the preservation of the collections and increasing requirements on accessibility. The aim is to deduce the problem by finding out how the different tasks relate to one another today.

Finansiella garantier - en möjlighet att säkerställa ett miljömässigt omhändertagande av uttjänta produkter

Extended Producer Responsibility (ERP) is a form of product take-back regulation that requires the producers to manage their products at the end of life. By internalising the products? entire life cycle costs into the market price the ultimate objective of such regulations is to reduce the environmental burden from the products. This Master´s thesis seeks to examine if the total life cycle cost of a product actually is borne by the producer, and if not, predict who will then take this cost. This is done by analysing the market for take-back activities in three different categories of products; electrical and electronic equipment, cars and wind power stations.

Förbättring av väggfäste för flatscreens

The project was carried out in cooperation with the department of product development IOS at IKEA. The work included improvements of a new existing product that Ikea soon will release on the market, Observatör, a wall bracket for flat screens. The product is supposed to fulfil the needs within this market for IKEA. However, since Ikea was not satisfied with it, our work was to carry out the improvements that were specified in the beginning of the project. Another task in the project was to develop a side-product that is supposed to be used together with Obeservatör for storage of DVD/decoders.The project included labour as problem definition to final technical drawings and a prototype.

Ett ärendehanteringssystem för mobila enheter

The purpose of this project was to create a system which can handle issues, with other words an issue tracking system. The system must create issues, assign issues to a specific user and list all issues for each user. On top of that, each issue should have a log where users can log whatever they want.My part of this project was to implement a client which can fulfill this basic criteria (and a bit more if possible), and communicate with the server which has procedures to be executed by the client.This system is based on Android and has it purpose to be used by mobile devices which support Android. ?Ichnaea? as the system is called, is meant to be used by companies to have human interaction through the network..

Att spara eller inte spara? : En kvantitativ enkätstudie av informationslagringssystem för vetenskapliga artiklar

Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.

Förvaltningsaktiviteter i verksamhetskritiska IT-system

Avsikten med vårt arbete är att undersöka vilka aktiviteter som en förvaltningsorganisation utför på sina IT-system och om det finns några skillnader i dessa beroende på om organisationen förvaltar åt sig själva eller om det utförs för kunds räkning. Detta som ett led i att ge de som arbetar med, eller kommer att arbeta med, systemförvaltning en inblick i eventuella skillnader mellan förvaltning av egna system och förvaltning av en eller flera kunders system. De slutsatser vi dragit ur denna undersökning är att det inte förekommer skillnader i vilka aktiviteter som ingår i förvaltningsarbetet, däremot varierar det i vilken utsträckning man väljer att utföra dem..
