Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness

A computer model based on minimization of the free energy, capable to predict contact Angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

"Vem kan segla förutan vind?" - en kvalitativ studie om gatubarns livssituation i Delhi

The facts from the interviews are complemented with different researches about street children in general and not only about street children in Delhi. Our main question is "How is it possible for a child to deal with the street life in Delhi?".

Lyftkraftsberäkning för vingprofiler: Virvelpanelmetoden

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

Tillvänjning av labradorer att skritta och trava på löpband :

The aim of this study was to determine a method to habituate treadmill-naive Labrador Retrievers to walk and trot on a treadmill. 17 Labradors was equipped with reflective markers glued to the skin. Their motions were captured with six 240 Hz infra-red cameras as they walked and trotted on a treadmill three times a day for two days. Also the heart-rate was recorded. We then used QTM and custom built software to analyze the measurements.

Hells Angles och Bandidos i Helsingborg

Studien berättar om vilka Mc-gäng som har florerat i Helsingborg och hur dessa gäng har påverkat samhället. Här finns bakgrunds berättelse om Mc-gängen, dess struktur, uppbyggnad och syfte. I studien framkommer även information från en medlem om livet som Mc- kriminell, synen på polisen och deras arbete mot Mc-gängen. Personal från Helsingborgs polisen har fått svara på frågor som framställs i ett senare kapitel. Syftet med min rapport är att delge övriga städer, kommuner men även nya poliser kunskap om hur arbetet mot de kriminella Mc-gängen ser ut och hur arbetet har förändrats genom åren samt vad det har gett för resultat.

Den privata läsupplevelsen blir social. Tre kvinnor i en läsecirkel berättar

The purpose of this Bachelor Thesis is to examine what happens when the solitary reading experience becomes a social activity. The study is based on semi-structured interviews with three women belonging to the same reading group. I have used Sten Furhammar?s reading dimensions and categories to explain their reading experience, and Jenny Hartley, Elizabeth Long and Immi Lundin to explain the function that the reading group has for them, and the relationship between reading experiences in a book-discussion.My result shows that they started the reading group because they lacked an opportunity to discuss their readings with people that had the same interest in books. They do all have different ways to read, which is displayed by Furhammar?s categories personal and impersonal reading for experience.

Fjärrstyrning av videokamera

On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain Angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.

Automatiskt Nödstopp

In today?s industry it is starting to get more and more interesting with wireless systems and solutions for applications. To be able to reduce the amount of cables drawn to various machines which takes both space and an extra fee for every cable drawn. Some systems might require the user to use a handheld device that is directly connected by a cable which in some machines might be inelegant for the user.The goal with this bachelor thesis is to develop wireless monitoring of the machine operators position that is working with heavy industrial machinery. The thesis started out with researching different techniques for positioning a transmitter indoors, this was done in order to get a better understanding on how to go about.

Visioner och planer för framtidsstaden Ulriksdal. En studie om planeringen av en ny stadsdel.

The centre of attention in this essay is on public-private-partnerships in Swedish city planning. It discusses the phenomenon and tries to identify the problems and possibilities that may appear when private and public actors are trying to work together to plan new cities or parts of cities in a process with network structures. The main questions that is asked is ?what vision for the city can we se, and who's vision is it?? together with the question of where the actual power to make the city plan and the vision can be find. The soon-to-be-built area Ulriksdal in Stockholm were Peab AB and Solna Stad stands as main actors has been chosen to illustrate the possible problems and is analysed from different Angles, but the writers intention is also to say something on the matter in general.

Studie av integration mellan rategyron och magnetkompass

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading Angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

Kan strålar av ljus tyda det förflutna? : Användning av Reflectance Transformation Imaging (RTI) för att tyda runinskrifter på Pireus-lejonet

This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different Angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast.

TAKK - en möjlig resurs för barns kommunicerande? : En kvalitativ intervjustudie med pedagoger

The purpose of this essay was to determine whether signs as alternative and augmentative communication is one possible resource for children?s language development. Based on my research questions How educators perceive the importance of SAAC as possible resources to enhance children's communication?, For which children is SAAC used? and How does educators perceive child?s best in communicative interactions? have I interviewed six educators in two different kinds of municipalities with different kind of positions.In my background I lift the importance of communication for the human being, what happens to the children who doesn?t get stimulated to their language and child?s best. My literature has shown that children need to have an incentive to acquire a language and that SAAC is mainly created for children with special needs.

Biblioteket som integrerande resurs i samhället. En exemplifiering med målgruppen romer

This essay is about how the library can make a difference inintegrating the minority Roma people into the Swedish society.Roma people have been subjected to persecution anddiscrimination for a long time. In this essay, I examine theactivities, functions and capabilities of libraries that can have apositive effect for the integration of the Roma people. Myquestions are: How can libraries reach out to the Roma people andwhat function do the library have for the integration of the Romapeople? I have used Marianne Anderssons and Dorte Skot-Hansens theory the four functions of the library ? the culutralcenter, the knowledge center, the information center and the socialcenter. Based on this theory, I have interpreted and analyzed thematerial that I have gathered through interviews and literaturestudies such as thesis, dissertations, repors and parliamentdocuments.

Maskinduglighet på planlaserskärare

Lars Höglund AB is one of Scandinavia?s most qualified manufacturers of sheet metal products and provides custom designed products of very detailed precision. One of the main methods of manufacturing is laser cutting. When Lars Höglund AB signed up a new customer, with high demands in tolerances for the products, Lars Höglund AB thought it would be necessary to know the capability of the laser cutting machine. Also the process of how to retrieve this capability was interesting. The capability will be researched for the following elements: Cutting right Angles in squares with a corner radius of 1 mmCutting corners which are not right angleCutting of circles with constant radius Measurements were made on 150 pieces of sheet metal details, which had been cut out by the machine.  The data from the measurements where later used to study the capability.

Biblioteket som mötesplats ? vad menas med det?

This thesis examines how library employees experience the library as a meeting place. Our questions are: What effect has the concept of a "library as a meeting-place" for library staff?How do they see the library as a meeting place? How do they see their workplace as a venue for meetings? The respondents interviewed work in public libraries. We were inspired by a cultural geographic theory that we re-designed. The following divisions were made in order to give the work a definitive structure:The "mental space"The library as a meeting place on a global and universal level;The "conceived space"Librarians and planners' thinking on the specific library as a meeting place;The "living space"How library staff perceive that the library is used as a meeting place in reality.In our analysis, we use a phenomenographic qualitative interpretive methodology.
