Alkohol bland ungdomar:En litteratur studie : Hantering och identifiering av ungdomars alkoholproblem, missbruk och beroende.
The aim of the study was to describe how nurses experience to handle the alcohol issues among young people and how they can identify young people?s alcohol problems, abuse and dependence. Empirical articles were searched in the databases Cinahl, Medline(Pubmed) and Discovery and resulted in the inclusion of 14 scientific articles. The results showed that nurses find it difficult to raise the issues of alcohol with young people, this partly because they feel that they have too little knowledge and that it is an emotional issue to raise. There is help instruments available that nursing staff can use to raise this issues and to identify alcohol problems, abuse and dependence.

Utveckling av reglersystem till quadrokopter
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.

Validering av glidande statorfötter på Hissmofors G6 och G7
Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.
Masshantering av schaktmassor : en jämförelse mellan traditionell masshantering och GPS-styrd masshantering i realtid
The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.
Påverkan på energianvändning och termisk komfort vid reglerinstabilitet
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.
Aspect Analyzer: Ett verktyg för automatiserad exekveringstidsanalys av komponenter och aspekter
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.
Användbarheten i säkerhetskritiska system: en fallstudie av SIGMA-systemet
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.
Läsa skönlitteratur i skolan : Hur pedagoger motiverar och stimulerar alla elever
AbstractThe purpose with this study is to find out how pedagogues, who teach in the early years of primary school, motivate and stimulate all pupils so they want to read a lot of fiction. The research also includes finding out more about why the pedagogues work as they do. The research starts with a study of current literature which deals with how teachers should work with motivation and stimulation in school. To find out how the pedagogues work in school I have made qualitative interviews with four pedagogues who work in the early years of primary school. The result shows that all of the pedagogues motivate and stimulate pupils in similar ways.

Elevers vardagsuppfattningar om tekniska system
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.
Hur påverkar regeringen företagens internationella konkurrensfördelar? : En studie av den svenska miljöteknikbranschen
Sweden experienced a decline in exports of 16 percent in the period after the financial crisis. The decline has created a lot of question marks regarding the traditional exports which has started a process with the aim of finding Sweden?s next cash cow in export.Sweden adopted stringent environmental laws early which positioned them as a strong nation in environmental awareness. The stringent environmental legislation meant that the Swedish companies were required to minimize the environmental impact, which created a demand for eco-efficient products. Despite the early demand for eco-efficient products, the international success of the Swedish cleantech companies has been modest.The government can increase firms international competitiveness by encouraging, supporting and promoting activities on the domestic market.
Strategi för IKT i skolan ? att integrera teknik i ett komplex sammanhang : Mätbart, jämlikt, statusfritt
Today there are many studies that have shown positive results in the treatment of ICT at an early age. The focus of the studies vary, and they target everything from the actual implementation of teaching resources in ICT, to student performance with ICT support. Regardless of the amount of studies on the subject, there is no precise strategy for how to implement, working with ICT, integrate ICT in different subjects, utilizing the hardware and software that is or how it will eventually respond to new technologies. This work will there by focusing on trying to develop a basis for further research and hopefully in the future to develop an ICT strategy at a national level.In order to provide a basis, a comparison was made of ten different schools. The schools were entered into a table showing the similarities and differences .
Prototyp av informationssystem för militärfordon
Computer based information systems play an important role in modern military combat vehicles. The crew needs to be able to quickly get information about both the vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.
