The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.

The purpose of this report was to identify the current waste management of non-hazardous construction and demolition waste in a few Swedish construction companies, based on the different steps in the waste hierarchy with a focus on waste prevention, reuse and recycle. Additionally, the purpose was to attempt identifying opportunities, obstacles and as well as to propose possible solutions from an environmental perspective. The method used was a qualitative study using interviews conducted through emails and phone with employees occupying positions that could answer this reports questions. The results of this report indicates that waste management of construction and demolition waste has improved, and less waste goes into landfills. The concern is that the overall amount of waste being produced is not decreasing, thus calling for actions preventing the production of waste.

Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.

The industrialization of construction is increasing in Sweden which leads to higher demands of prefabricated components and cells. But what does the business of construction think of the industrialized business and what can be done in order to decrease faults and errors with these products? Today we have many manufacturers who have different technical solutions which might lead to difficulties when assembling components and cells at the building site. But by trying to make a more opened market, with possibly standardized connections details and improving the communication between the different participants, the prefabricated components and cells can be made and assembled with less errors. This is something that needs to be done in order to establish a more secure business, and especially when working with new companies and methods, when using industrialized products..

We have done a qualitative and quantitative study about math problems on second­ary school students. The study is based on the diagnosis, treatment and training of teachers, about students who have math difficulties. The aim of this work is to obtain teachers ?perceptions about students? diagnosis, treatment / improvement and continuing education for students who have math difficulties. By having interviewed various teachers through surveys we have received answers to their concerns about the diagnosis, treatment and the importance of continuous training of teachers on students? mathematics difficulties.

The survey aims to shed light on traditional and contemporary bottom floor frames, their construction and different insulating materials; mineral wool, wood shavings and charcoal. The purpose is to analyze and discuss the similarities and differences as well as the pros and cons with a focus on the construction and the different insulating materials. The work has been limited to comparing two different wooden floor frames. The first one is based on a real floor frame from an older building, this example is presented as the traditional floor frame in this study and are from around 1940. The other floor frame is presented as a contemporary floor frame and is based on wood building type descriptions and literature.

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

The idea to create authentic learning situations where students are highly integrated made me want to try to develop a new method in the course Restaurant and Catering B MAKU 1208 (another field practicing cuisine). In my quest to do just the practical part as rewarding, stimulating and efficient as possible for the student, I planned for a training model with   focus on group interaction.The implementation of the model for learning was to strengthen students confidence both in themselves and in each other, stimulated to greater cooperation and it has also provided an incentive to the student's own development but not least, a growing self-confidence for many students. Several have also had an increased sense of knowing something, to have something to contribute and that their labour input actually was needed. While highlighting that further education to seek knowledge strengthens the individual's skills and consolidates and increases deeper knowledge in the professional field.In conclusion, training should be done in both individual and group basis for optimal learning process..

This report is on concrete work during the winter and is implemented on Peab?s behalf. The assignment was to describe the differences between a summer- and a winter casting. While it shows the complications that exists, it also show what aids are available, both electronic via computer and physical aids.The information that I have developed is originally from theory in books, information on the internet as well as practical experience from knowledgeable people that works in construction output. Other theories are those I have learned throughout the education to become a construction engineer, including all oral sources over the years.The results I have come up with, I hope will be able to help future construction projects in the planning phase of a winter casting.

Virtual communities are a phenomenon that is becoming more common as the information technology comes with in reach for the general public. This report will bring the theories and construction of a virtual community together. The purpose of this report is to describe the different theories that have emerged from the research within this field and to examine the work procedures that have been used during the development of a site for a MDA-community. The MDA-website is a homepage on the Internet that was developed to bring the students closer together. The report describes the work of the project group, why the website was not completed and at the end the theories are looked at on the basis of the construction of the website..

For most dog owners today it is natural to use acoustic stimuli such as talking to communicate with their pets. Words are used both to ask the dogs to perform tricks, as well as to hold ?conversations? with the dog. This literature review looks at how dogs perceive human acoustical communication and how this can influence the behaviour of the dog. This information could be used e.g.

AbstractHeadline: Young trouble and teenage love (Fjortisgrubbel och tonårskärlek)Number of pages: 37Author: Annika IlmoniTutor: Amelie HössjerCourse: Media and communication CPeriod: Autumn 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/aim: The purpose of the work was to produce a comparing study of two Swedish teenage films from different periods of time, 1970 and 2005. An analysis was to be made of how love between teenagers as well as the heterosexual relationship in general was depicted in each of the films and further investigate the gender construction in both films.Material/method: With the intention of narrowing down the complexity and make the evaluation more lucid 5 scenes from each film were used for comparison, these were chosen through the Anglo Saxon dramaturgy. To make the scenes more comparable 4 factors were used for analysis in each scene, these were: clothes, recreational activities, behaviour and environment. Beside the above given factors the heterosexual relationship were analysed and compared in each of the scenes through the theory of dominance in dialogue.Main results: The gender construction occurs obliviously in the older film from 1970 while taking place in a more conscious way in the film from 2005. Further on the heterosexual relationship is perpetually depicted in the 70?s film with a submissive girl and predominant boy, the same dominance is easily seen in the more recent film but with a higher rate of equality as the girl is portrayed as the dominant character in almost half of all scenes.

There is a lot going on in the construction business right now. It feels like everywhere you turn there is a building sight. Furthermore the business is heading a generation change and the need of recruiting new construction engineers is huge. How is the business going to handle the transition that they are facing? The question has been in progress for at while and I wanted to find out what the current students feel about taking the step into the working life and replace the veterans.A research is made about student?s opinion about their education and future work life.

Syftet med examensarbetet är att hjälpa ett företag med att införa standardlittera för deras prefabricerade betongelement som ingår i deras Konceptet. Införandet av standardlittera ska resultera till att återfinna och gruppera deras betongelement i CAD-systemen. We did our thesis project at one of the most prestigious Swedish construction companies. We have examined the possibilities of doing sandwich elements to standard elements which would increase the degree of industrialization. The company has developed a concept that is based on a more refined process of industrialization.

Sammanfattning Detta arbete beskriver de studier som utförts vid implementering av Last Planner planeringsmetod, i projektet att bygga LKAB:s flotationsanläggning i Svappavaara. Studien har bedrivits vid institutionen för Samhällsbyggnad i Luleå och LKAB:s malmförädlingsverk i Svappavaara. Arbetet inleder med en granskning av litteratur om teorier och grundtankar om Lean Construction. Filosofin bakom Lean Construction bygger på att avlägsna alla processer som inte skapar mervärde för kunden. Tankegångarna kommer från den Japanska bilindustrin och då främst från Toyotas framgångsrika produktionssystem TPS.
