Denna rapport avser att undersöka för- och nackdelar med att utveckla ett för ändamålet specialanpassat system eller utnyttja de standardsystem, som i det aktuella fallet tryckerikoncernen JMS redan äger och använder. Genom en mer noggrann definiering av ickefunktionella krav på bland annat användbarhet har en specialanpassad prototyp framställts. I projektet användes metoder för kravinsamling som ledde till en kravspecifikation och i sin tur slutade med en färdig prototyp. Prototypen jämfördes med två standardsystem genom användartester och intervjuer. Prototypen visade sig leva upp till de krav som upptäcktes.

AbstractThis paper discusses how system development methods today support communication between system developers and their customers and end users. Today there are many system development methodologies with different aims and emphases. It is difficult, however, to find among these methods those who promote good and effective communication with customers because so many of these are very technically rooted and not as much directed towards the soft aspects of systems development - i.e. Human aspects. Our own experiences tells that a simple interview can be initialized without us having an idea what to ask the customer about or how to structure it up - nonetheless it?s done, but the outcome is just chance.

This paper investigates the internal product costing system in one of the Swedish banks with the purpose to evaluate the quality of its product costs and possible implications on decision making. The study shows that the current system distorts product costs by, among other things, using relative allocation of costs and time and by allocating all costs to individual units of products. We therefore propose an alternative product costing system, which mainly draws on ABC theory but is also adapted to the specific needs of service companies and of the Bank. This proposal is intended as a solution in this particular case and not to be generalized in other contexts. We hope however to add to the understanding of why more complex costing systems, such as the ones based on ABC theory are, according to previous studies, not widely used in practice.

The intention has been to look at the school system in South Africa and specifically at arts and culture in grade 10 to 12. I have visited a number of classes and interviewed the teachers working at the art centre PJ Olivier in Stellenbosch. By doing this I wanted to get to know the system and to understand the intentions that the curriculum describes.I have all through the study related the areas I?ve looked at to the curriculum to see how well the intentions are implemented. I have also compared everything with the Swedish school system.The curriculum has good intentions but the country has a lot to do before they reach the goals with a school system where everybody is included and where there is ?ubuntu? (Zulu word for humanity or I am what I am because of what we all are).

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..

Problem: Our opinion is that it is important to consider about usability in system development. In this thesis we will focus on usability in point-of-sale systems. The point-of-sale system we base this thesis on is Extenda Retail. Our case study is performed on Ica Kvantum in Bromölla, which implemented Extenda Retail about two years ago. Purpose: The purpose of this thesis is to figure out what important factors there are to consider, in usability aspects, when developing point-of-sale systems, with focus on the cashier. We also wish to find out the cashiers opinions about the Extenda Retail system. Method: The information gathered for this thesis consists of literature and interviews.

Today an increasing number of schools and organizations are investing in so called Learning Management Systems. Researchers disagree on the pedagogical value of these tools. Some mean that Learning Management Systems cement old-fashioned behaviouristic teaching practices; others mean that the systems provide good opportunities in supporting learning in a socio cultural perspective. The aim of this study is to reach better understanding and increased knowledge of how the introduction of a Learning Management System influences the role of the teacher and how the learning is organized. We have conducted two case studies.

This project investigated the communicational possibilities between a Smartphone and a Raspberry Pi and based on the results that emerged the conclusion can be drawn that BLE is a protocol with many beneficial applications within industrial IT..

Ett konsultföretag får in anbudsförfrågningar och måste därmed göra kalkyler för dessa förfrågningar. Med hjälp av ett webbaserat system där en anställd kan göra kalkyleringar kan företaget få ett gemensamt sätt att arbeta och uppföljningen underlättas. Systemet som har skapats ger användare möjlighet att göra anbudskalkyler genom en överskådlig och lättarbetad webbsida, där man kan se förhållandet mellan företagets kostnad gentemot kundpriset. All information lagras persistent i en databas för att möjliggöra uppföljning och synkronisering med andra system som används på företaget..

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.

Syftet med den här undersökningen är att studera, och identifiera tillvägagångssätt för tjänsteföretag att internationalisera sig samt sälja sina produkter. För att göra det, samt att kunna kartlägga ett eventuellt mönster är det väsentligt att öka förståelsen kring hur försäljningen av tjänsten går till samt hur säljaren hanterar de kulturella skillnader som uppstår vid internationalisering. Vi har valt en kvalitativ metod, med en deduktiv ansats för undersökningen där utgångspunkt finns i teori. Den teoretiska referensramen inkluderar välkända modeller som beskriver företags processer vid en internationalisering, samt teorier riktade mot tjänsteföretag, internationell försäljning, säljarens roll samt kultur och kommunikation. Därefter har vi i det empiriska materialet, redogjort för vad de fallföretag vi har arbetat med, i praktiken har hanterat dessa fenomen i deras internationaliseringsprocesser. I analysen har vi sedan ställt empirin mot teorin för att identifiera ett mönster rörande internationalisering samt internationell försäljning av tjänsteföretag. I slutsatsen har vi till sist haft möjlighet att presentera detta mönster för internationalisering av tjänsteföretag, där vi har konstaterat att processen är baserad på drivna individer på ledningsnivå som initierar internationaliseringen.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.

The increasing complexity in the development of a configurable real-time system has emerged new principles of software techniques, such as aspect-oriented software development and component-based software development. These techniques allow encapsulation of the system's crosscutting concerns and increase the modularity of the software. The properties of a component that influences the systems performance or semantics are specified separately in entities called aspects, while basic functionality of the property still remains in the component. When building a real-time system, different sets of configurations of aspects and components can be combined, resulting in different configurations of the system. The temporal behavior of the system changes and a way to ensure the predictability of the system is needed.

I föreliggande studie undersöks hur användare upplever användbarheten i ett säkerhetskritiskt system ? Luftfartsverkets flygledningssystem SIGMA. Utifrån litteraturstudier definieras begreppen användbarhet och säkerhetskritiska system. Empirin utgörs av intervjuer med användare av SIGMA-systemet. Studien visade att användarna upplever att systemet i väsentliga delar har bra användbarhet, vilket utifrån litteraturstudier, intervjuer och efterföljande analys främst tycks bero på att systemet arbetats fram med stor användarmedverkan och att det var utarbetat specifikt för arbetsplatsen.
