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.

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.

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.

This composition is an qualitative study about unemployment and working life. The point of the study has been to make a larger understanding how unemployment can perceive by the individual and how this person can see and plan for future working life. This has been study with help from 8 intervirws. The paticipants has been umeployed between  6 months and 5 years, and they have workt arleast 5 year before the unemployment.The study has show that it is many different components who contribute to how the individual perceive the time in unemployment and how the planning for the future looks like. The persons who has been intervirws perceive their psycal health as god,, even but unemployment.  The study has even show that all the persons in the study want to come out from the unemployment.

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.

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.

In recent years coaching has become an increasingly popular phenomenon outside of the sports world. More and more people have found coaching to be a helpful tool for achieving greater performance and fulfillment in their lives. This thesis is a comparative literature study of three books about coaching where the authors use different theoretical bases to explain and teach coaching. The aim of the thesis is to explain how coaching as a phenomenon is described and compare these descriptions as well as to look at the ideals and norms that are produced and reproduced in the use of coaching. The study compares the three books from six different themes and shows that, in the use of coaching, the ideal of a rational and action oriented individual is constructed and the aim for this individual is some form of success.

The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Elever ska enligt kursplanerna i teknik få förståelse för de tekniska system de möter i sitt dagliga liv. Genom att eleverna får kunskap om teknik i allmänhet och tekniska system i synnerhet får de möjlighet att påverka sina liv som medborgare i en demokrati. I litteraturen saknas idag studier om elevers uppfattningar om tekniska system. Syftet med detta examensarbete är därför att studera vilka vardagsuppfattningar elever har om de tekniska system de möter i vardagen. Studien utgår från systemteori vilken ger en möjlighet att utnyttja det gemensamma mönster som kännetecknar analys av system.
