Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

In visual programming the developer specifies her code, using visual tools. Within the range of visual programming languages lay icon-based languages, form-based languages, and diagram languages.Mediator is a multimedia authoring tool that allows the user to create interactive CD-ROM presentations, dynamic HTML pages and Flash projects, without any coding or scripting. The user can create interactivity in her project, using event driven and icon-based visual programming, through a ?drag and drop? user interface. This report intends to determine some of the qualifications of a tool of this kind, as well as its limitations.The report is based on a case study, in which a smaller software application was to be updated using Mediator 9.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

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..

Ipendo Systems in Linköping, Sweden, is a small IT consulting firm developing among other things custom portal applications based on Microsoft Sharepoint 2010. The purpose of this thesis is to investigate whether the test tools TestComplete and LoadComplete provide sufficient compatibility for functional and non-functional testing of Ipendo Systems? Sharepoint based applications, as well as design testing related activities to be incorporated into their existing software development framework. A test process maturity framework was chosen and applied for the design of the testing activities, while the test tool investigation resulted in guidelines on how to apply the tools effectively and circumvent any issues discovered..

This master thesis has been carried out at Scania R&D at the department for Powertrain Control System Development during the winter of 2010/2011. In the thesis the writer examine and evaluate the existing method for collecting information from the tests carried out during the development of the Powertrain Control Systems software. It also contains suggestions for how a new method that enhance the validation elements could look like.The master thesis uses Vicentes theories of the ecological approach and theories of how knowledge sharing of tacit and technical information works within an organization and between the organization and its customers. First a workplace analysis at Scania R&D is carried out to see how Powertrain Control Systems work and how they test their software. Second a control task analysis, where the aims decided on after the interviews, is compared to the existing method.

This thesis aims to investigate SAAB AB´s possibilities to use synthetic instruments in their test systems. The reason for this is reducing costs and the risk of obsolescence which is common when test systems operate for several decades.The market around synthetic instruments has been explored in the search for suitable hardware and software. Software has been developed in LabVIEW and synthetic instruments have been created with the help of IVI-drivers. The hardware consisted of PXI-instruments (Waveform generator and Digitizer), connected to a computer using a fiber optic link and PXI-chassi. The created instruments was then compared to common instruments used today, and the comparison turned out well.

The advantage and the possibility of keeping track of a number of vehicles to make work practice more effective and smooth is today a favorable choice for Visual Units Logistics customers. We?ve been evaluating the software and trying to take it one step further and letting not only the individual user, but maybe, the company as a whole benefit from its advantages. This has been done by using methods like letting ourselves get to know the software, user case studies, workplace studies, interviews and future workshops. This resulted in a prototype introducing a new function designed with all collected data in mind trying to make the software, Visual Units Logistics, even more effective for the every day work practice of the user.

I vår produktion har vi tagit fram ett system för order- och lagerhantering, med vikt på realtidsuppdateringar, åt en extern mottagare där infrastrukturen inte hängt med i företagets utveckling. Vi valde detta projekt i syfte att bredda våra kunskaper inom både programmering och projekthantering. Denna slutreflektion tar upp den förundersökning vi gjorde för att kunna besluta om vilka verktyg vi använde i utvecklingen, den tar även upp vårt sätt att hantera och planera projektet. Under projektet har vi arbetat med en egenutformad arbetsprocess vilken även beskrivs här. --- Our production has been to design a system for ordering and supply management with emphasis on realtime updates to an external recipient, where the infrastructure has not kept pace with the development of the company.

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..

Syftet med arbetet var att ta reda på om den ökade tidsåtgången som parprogrammeringen leder till uppvägs av de fördelar som den genererar i jämförelse med enskild programmering där arbetet delas mellan två programmerare och sedan integreras. I arbetet presenteras resultatet från en enkätundersökning som sju personer från fyra olika företag i Sverige har besvarat. Samtliga personer som besvarat enkäten har arbetat både med enskild programmering och parprogrammering. Vårt arbete bidrar till forskningsområdet programvaruteknik som intresserar sig för mjukvaruutvecklingsmetoder. På senare tid har detta forskningsområde också intresserat sig för lättrörlig mjukvaruutveckling där utvecklingsmetoden Extreme Programming (XP) ingår.
