C3LOOPS is an application for DJs and VJs based on surface interaction. A system is said to be based on surface interaction if it presents content on a two dimensional, endless surface that a user navigates through zoom, pan and incremental text filtering where processing is tightly coupled with the content without breaking the workflow. C3LOOPS is designed to encourage improvisation and collaboration. During improvisation changes occur rapidly. Allowing navigation through time as well as the two spatial dimensions of an interaction surface the possibility of unlimited undo operations opens up.

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

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.

The purpose of this thesis has been todesign an electric circuit that measurestemperature in three different ways. Asoftware was also designed to record andanalyse the measurments. The result of thecircuit was a PCB with inputs for 42sensors of both surface and non-surfacemeasurments. These all have a maximumerror of ±3°C..

This thesis investigates three different surface modifications, and the route to design and synthesize them. The thesis is therefore divided into three sub- projects. (i.) Design and synthesis of a peptide which secondary structure could be controlled by a negatively charged surface. (ii.) Design and synthesis of a cyclic peptide, that would self-organize prior to surface interaction, using the type I anti-freeze protein of a winter flounder as template. (iii.) The use of solid-phase synthesis to make the synthesis of SAM-molecules easier..

Användarupplevelser är en gren inom användbarhetsområdet som på senare år kommit att studeras alltmer. Orsaken till detta är att ny teknik medför andra krav på produkter än att produkter som sådana ska vara lätthanterliga. Produkten kan likväl ha som syfte att vara rolig att använda sig av.Studiens syfte var att studera användarupplevelser beträffande Surface-computing teknologi.Företaget Interactive Institutes innovativa Surface-computing produkt Virtual Autopsy Table fick exemplifiera Surface-computing teknologi i publika miljöer. Genom att använda denna uppmärksammade produkt som underlag är syftet att undersöka vilka designmoment som kan anses vara kritiska för upplevelsebaserad design. Studiens frågeställning blev:Vilka riktlinjer kan tas fram för att vägleda en designprocess att bli mer fokuserad påanvändarupplevelser vad gäller Surface-computing system?Med utgångspunkt från studiens datamaterial, så var en del av studiens syfte att ta fram riktlinjer.

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

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.

Detta  examensarbete  undersöker  skillnaden  i  tre  olika  nybörjargruppers  upplevda flow  då  de  spelat  Magicka  (2011)  med  motståndarantal  som  den  enda  skiljande variabeln.   Undersökningen   baseras   bland   annat   på   Csikszentmihalyis   (1990) flowteori och Caillois (2001) teori om att tävlande slutar vara roligt då det  urartar i kaos.  Syftet  med  examensarbetet  har  varit  att  hitta  när  mest  flow  uppstår  då nybörjare på Magicka (2011) spelar mot  en viss motståndartyp, samt om  detta flow bryts  när  för  många  motståndare  introduceras.  Undersökningen  har  visat  att  nio motståndare har resulterat i betydligt mer flow än tre, medan skillnaden mellan nio motståndare  och  18  har  varit  obetydlig.  Examensarbetet  har  dock  inte  lyckats kvantifiera  var  flow  övergår  till  kaos  med  den  testgrupp  och  motståndartyp  som använts.  Framtida  forskning  skulle  exempelvis  kunna  undersöka  på  vilket  sätt  ett varierande  motståndarantal  skulle  påverka  flow  för  en  mer  erfaren  testgrupp  som spelar mot andra motståndartyper..

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

The purpose of this Master's thesis is to contribute to a betterunderstanding of children's free time reading book practices by studyingpupils in the school library and their processes of finding and borrowingbooks for themselves to read silently in the classroom, so called free timereading books. The study also includes observations of the staff's role,particularly the school librarian's in supporting pupil's book selection.The empirical material consists of field notes from an etnographic studywhere pupils in 4th grade (aged 10-11) and staff were observed duringthree school library visits. The theoretical framework is inspired byLennart Björneborn's concepts of information practices in libraries:serendipity, integrative library interface, mediation flow and affordancespaces.The study shows that pupils' search for free time reading books in theschool library is relatively routine-based at the same time as it isspontaneous. The process is an interplay with factors such as time,display and interaction in the integrative library interface. In the presenceof adults, finding books becomes an imposed task for the pupils.

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.

Starting out as a minor form of amusement, the game industry has become one of the most lucrative andsuccessful in the entertainment business competing against giants such as television, movies and music.As the internal competition within the developer community grows companies work hard at discoveringnew ways to attract and keep customers. By having a playcentric approach focusing on user experiencethey hope to achieve that goal. This thesis describes the process of designing a game with focus on theplayer. We apply the concept of flow on game development and investigate through research throughdesign if we are able to create a game that keeps the player in flow.Play tests showed several elements such as control issues and too difficult challenges early in the game,affecting the possibility for players to experience flow while playing. These negative factors came to becalled flowleakers.
