Web Services har vuxit i popularitet de senast åren. Användningen av inbyggda systemökar också ständigt, och möjligheten att göra inbyggda system tillgängliga via Web Services öppnar nya möjligheter.Detta arbete visar på möjligheter och problem med standardiserade textbaserade protokoll för kommunikation i inbyggda system med små resurser. XML-RPC och SOAP studeras ur detta perspektiv. SOAP befinns vara mer komplext att implementera stöd för än XMLRPC i den begränsade testmiljön, som har 32kB internminne. XML-RPC visar sig ge fördelar över proprietära protokoll främst när det gäller underhållbarhet och återanvändbarhet..

This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets, treatment in which, nutrient solution was based on Vortex-treated water was compared with an control using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and internodal length were significantly different in tomato plants grown in Vortex-processed water compared with the untreated control.

Vi har undersökt ett verksamhetskritiskt system i en större organisation för att se hur systemet är konstruerat och hur förvaltningsarbetet bedrivs för att undvika avbrott i systemet. Då det är särskilt viktigt att dessa system har hög tillgänglighet har vi försökt lyfta fram faktorer som visat sig vara särskilt viktiga för att uppnå hög tillgänglighet. Undersökningen har genomförts som en fallstudie där vi intervjuat personer med olika befattningar inom organisationen. Vi presenterar även ett antal rekommendationer som vi tror kan minska risken för avbrott i det undersökta systemet..

The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

Under de senaste åren har webbplatser blivit allt mer komplexa och informationen som ska visas och hanteras allt större. För att underlätta hantering och administration av dessa system har många CMS-system vuxit fram. Dessa system kan skilja sig mycket beträffande pris och funktionalitet, allt från mindre open source system till stora komplexa kommersiellt drivna system. Detta arbete bygger på att skräddarsy ett CMS-system för administration och hantering av innehåll på diverse artist sidor, som hanteras av ett medieföretag. Systemet använder tekniker som JavaScript, PHP, MySQL som grund för dess uppbyggnad.

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.

This report describes the development of a system for controlling documents. The report starts with a problem description which the company wants an intranet-based solution for. The report then continues to describe the development phase for the different parts of the system which results in a complete system. 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..

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..

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..

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.

Many companies are currently working to optimize and streamline their processes and production lines to achieve higher profitability. In increasingly competitive markets, companies are working to find solutions to increase the value of their production with such a small use of resources as possible. A tool used to accomplish this is the Lean management system. Lean comes from the production system that Toyota has been developing since the early 1900's, The Toyota Production System (TPS). The Lean philosophy helps companies, by working towards continuous improvement in its operations, to achieve higher customer satisfaction, more efficient production and ultimately higher profitability. Many companies are working to implement Lean in their organization. But there are many who fail to implement a complete change towards Lean.

In this study we have interviewed eight teachers about when and how particle concepts should be taught. All of the surveyed teachers argue for an early introduction. This view is also consistent with the scientists on when the particle concepts should be introduced. By an early introduction teachers and scientists consider the age between 6-12 years old. A majority of the scientists and the surveyed teachers use concept of change as a entery point to talk about particle ideas.

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..

This thesis has been carried out in collaboration with LEDtec International AB. LEDtec focuses on innovative solutions in LED screens. Everything from large advertising signs to welcome signs in cities, to screens indicating speeds or warning of heavy traffic. The task was to was to help them develop a new version of the control board that is used in some of their products. The reason for this is that their old control board is obsolete and the components that are on it, is no longer manufactured or in need to be renewed.

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..
