Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

In this empirical study I have investigated how preschool teachers relate to the free play at the preschool. At the same time I have investigated how the free play is adapted into everyday practice in the preschool. Previous research shows that children process what they experienced in the free play. The child retrieves content to play with through things they have experienced, such as family life, preschool and so on. To play, grow and continue, it is important that free play may take place and space in the daily activities at the preschool.

As a leisure time pedagogue I find it hard to have an insight into what children are playing, and how they play when it comes to free play. My experience is that in some free play, conflicts arise, which reveal hierarchies and power structures containing violations, whereas other occasions of free play suddenly come to an end as the pedagogue interferes. In this essay I investigate my responsibility as a leisure time pedagogue during children´s free play, based on two differing play situations. I also investigate the play as a phenomenon by looking into previous research on children?s play and development psychology.

With my bachelorwork I aimed to design a new mobile ?livingspace? which should become as small, functional andeasy to assemble as possible.The ?living space?is made for people who are interested inhaving a biking vacation and getting more close to naturebut at the same time wish to have a comfortable and easyway of traveling and living. The ?living space? is a multipurposevehicle which you transport with a bicycle. Thevehicle contains a kitchen with workspace, a refridgerator,space for luggage and a comfortable sleeping space.In my workingprocess I made research, sketches and modelsto find a functional solution..

The phenomenology of Gaston Bachelard holds that readers, or viewers, relate to spatial imagery through the use of age-old archetypes. These archetypes form a collective image-memory that is employed when reading space. One such image is the house. The house for Bachelard is, however, never solely an image, but constitutes a familiar space that becomes inscribed in our bodies through the repeated physical contact with this domestic space. The house teaches us to interact with space, and comes to inform the way that human beings understand images of space.

Today's planning strategy, densification of cities, makes it difficult for municipal authorities to find spaces to build preschools and daycare centers on. The Planning and Building Act , Chapter 8, § 9 states that " if the site should be developed with buildings that contain one or more dwellings or premises for after-school , preschool, school or other activities, it should be on the property or near it, enough free space which is suitable for play and being outdoors. " Each municipality has to define the expression enough free space and a number of municipalities have established guidelines for preschool and daycare centers concerning dimensions. The guidelines measure the number of square meters of free space per child with the aim of contributing to a qualitative environment. But the size is just one quality and the issue is how other non-quantifiable qualities are taken into account in the planning process. The paper compares three municipalities, Gothenburg, Malmö and Lund.

This Diploma work investigates internal air ventilated crawl-space in respect to construction and damp. The Diploma work assumes from a general description of crawl-space and general dump problems in ground construction. An internal air ventilated crawl-space is a construction where you take the ventilation air from the building and bring it down to the crawl-space and lets the air circulate before it passes through a retaining aggregate on the way out from the crawl-space. In this matter you get a worm space under the building and a lot less dump problems in form of · Ground damp · Build damp The ground dump reduces through draining around the building, different layer of gravel between the ground and the building and ventilation of the crawl- space. The build dump reduces through ventilation of the crawl-space as fast as possible.

Early during my education to become an afterschool-teacher a concern was raised that afterschool-programs will continue to be seen as an institution for childcare services. In this experience-based essay, I discuss what I see as the coreproblem: the free- and planned activities. What do the free- and planned activities actually mean for children's development and what is it that determines how much space the various activities will be allowed to take?In my attempts to answer this question, I go through the concept of leisure, the importance of children?s play and adults responsibilities in children?s play, what the different policy documents say about children?s play and the creative work, staff skills and theoretical and practical knowledge. I question whether I was right in the story that I begin this essay with, and conclude that it is more difficult than I previously thought to find an answer to the question..

The purpose of this thesis is to bring forward and discuss the American vision for space exploration found at NASA's homepage, how the vision is popularised and why. NASA's homepage is analyzed as popularized science and the theoretical perspective emanates from the field of popular science and especially the work of Johan Kärnfelt. The historical reference is made up by Howard E McCurdy and he's thoughts about space and the American imagination. The analysis is based on a number of documents that popularize the vision for space exploration and is intended for the public. These documents describe the future plan for NASA and US space exploration..

AbstractGroup processes within the free play- in a socialpsychology perspective In our socialpsychology study we have demonstrated how children?s free play is by observing 2-5 years old children in preschool. We have also interviewed two preschool teachers. The major subject in this study is how children?s group processes expresses in their free play.

We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.

The purpose of this thesis is to study five pedagogue?s view of the free play and their view of the importance of the free play for children´s learning and development. I have chosen to use a qualitative research method in the form of interviews with five pedagogue´s from a preschool. The main research questions asked were:What have the pedagogues of view on the free play? How important believe the pedagogue that the free play is for children?s learning and development? What has emerged in the study is that educators have a positive view of the free play. They believed that the free play is important for children´s skills.

The objective of this master thesis was to study the relation between public green open space and health among adolescents in Uppsala municipality, Sweden. The aim of the study was to investigate if there is an association between the access to green open space in the living environment and adolescent´s health, in terms of fysical activity, self- reported health and overweight. The public health questionnaire ?Liv och Hälsa Ung 2009? provided data together with a map over public green space, where the measure taken into account is the proportion of public green space in the living environment. The study includes 3423 adolescents, 12-19 years old.

Reflections är en stämningslampa som med hjälp av invävd fiberoptik lockar fram nya visuella och taktila uttrycksvärdeni en textil. Under arbetets gång har jag utforskat mängden ljus som fiberoptisk textil sprider längsmed fiberlängden samt undersökt naturfiberns egenskaper när den vävs samman med fiberoptik.En stor utmaning var att hitta balans mellan tekniska begränsningar och det uttryck jag sökte. Lampans formspråkär min reflektion över dagens stadslandskap där arkitekturens geometriska former möterfordons strömlinjeform. Med stämningslampan hoppas jag att hitta och inspirera till nya användningsområdenför fiberoptisk textil.Reflections is a mood light using interwoven fiber optics witch brings out new visual and tactile expressionvalues in a textile. During the work, I have explored the amount of light fiber optic textile spreads along thefiber length and examined properties of nature fiber when it is interwoven with fiber optics.A major challenge was finding a balance between technical constraints and expressions I was looking for.

The purpose of my study is to examine how four teachers reflect on free play and controlled play in preschool. What are their reflects concerning free play, controlled play and children?s development and education. The main focus of this research is the experiences of the teachers and I compare their perspectives against each other regarding free and controlled play.To be able to realize this study, I propose the following questions:What kind of vision does the teacher have concerning free play and controlled play?According to the teacher, how does playing affect the children?Which development areas are affected by participating in the play?This is a qualitative study, based on interviews with four teachers from two different preschools.
