Through wing pattern, posture and movement, a harmless moth of the family Brenthia imitates an eight-eyed jumping spider. When an octopus of the species Thaumoctopus mimicus sense danger it can alter its appearance to that of a venomous sea snake. They are both drawing attention to themselves. Nevertheless, and because of this, they are protected. The mechanism is called mimicry.

Inspired by how to sketch a light cone from a flashlight in a comic I wanted to create an armature carried only by its own light cone. To manage this challenge I sketched in an architectural and sculptural way, where I chose to ignore the function of the lamp as long as possible.As a result I developed an armature with a stunning shape, with an illusion that it was carried by its own light cone. It could be hanged on a wall, placed on a table, pushed against a ceiling or standing on the floor.Depending of its size the light cone from the light source lightens up the surface and draws attention to the otherwise forgotten wallpaper or the undisposed statue in the darkness of the city..

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

The purpose with this thesis is to get a compilation of all the critical bolted joints of all enginesproduced at LV Motors. ABB LV Motors produces induction engines with seven shaft heights. Eachengine size exists several variants of components ex. standard shield and flange shield. Depending onwhich components the engine is equipped with arises various types of strains in the engine's parts,certain assembly ways are more favourable than other.The most critical parts in the engine from a mechanical point of view are the screw units betweenshield/stator, feet/stator and bearing cover/shield.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

At Sandvik Materials Technology, Argon gas is used as furnace atmosphere when heattreating hot rolled wire. Upon heating chromium steel wire, a rich oxidelayer forms on the wire surface. The abstract of this masters thesis is to enhance the understanding of the constitution of the oxidelayers and the influence of the furnace atmosphere. This will be achieved by performing a number of annealing experiments on laboratory level. Also, the aim is to understand the chemical reactions and physical mecanisms controlling the pickling process.

Due to an increased population in cities the need of densification of cities increases. This means that the amount of ecological elements in the city is at risk of decreasing. Ecological services contribute to the city?s climate by softening the negative impacts that densification of cities means. Thus increases the will and ambition in city planning in to preserve greenery.This is an interdisciplinary thesis within the subject of geography that studies Biotope Area Factor (BAF), a planning tool that is used in city planning with the purpose of compensating for lost ecological services associated with new housing estate.

Hoppsasteg ? med känsla av glädje är ett examensprojekt som pågått under 20 veckor. Namnet har jag valt för att det är en känsla som jag vill uppnå under perioden. Syftet har varit att genomföra projektet med lust, göra figurativa, svartvita mönster med ett tecknat uttryck och att göra en flexibel möbel. Mönstren har ritats i tusch, det har tryckts på både tyg och tapet.

This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..

This thesis examines the gender boundaries in sports. I do this by exploring three cases in which these boundaries, at least on the surface, have been questioned: the transsexual tennis player Renée Richards, the east European runners Marita Koch and Jarmila Kratochvilova and the Swedish golf player Annika Sörenstam. The results point out different mechanisms that contain the"danger"and restore"security". But they also point out a criticism against the struggle for equality in sports, which is based on the preserving of differences and therefore cannot challenge the ideological assumptions about gender in sports..

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

 Knitting Big är ett undersökande examensarbete i textildesign med fokus på stickningens möjligheter och förmåga att skapa tredimensionalitet i relation till en möbel. Syftet var att få kunskap i stickningens möjligheter till volym samt att svara på frågeställningarna: Hur förändrar den strukturerade textilen intrycket av formen? Jag vill även ta reda på vad etablerade möbelföretag anser om trikåns möjligheter inom möbeltextil. Projektet har utformats i skolans tre trikåtekniker: handstickning/handmaskin, industriell rundstickning samt industriell flatstick. Under projektet har jag samarbetat med möbelföretaget Homeline.

The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
