ELVEEL - grafisk identitet till klädmärke

In my project I have collaborated with Linda Larson, who is the creator behind the fashion brand Elveel. The goal was to produce an identity and a graphic profile for Elveel. The aim was that the graphic profile would act as an extension of the clothes aesthetics. I wanted to explore if I by different folding and cutting techniques, in tags and packaging, could reflect the details of the clothes expression. But also how different design elements can reflect the story behind the clothes.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Maskinskydd på rullriktverk

ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.

Säkerhetsbrytare för Gräsklippare

This thesis describes teh solution of two problems regarding safety on powered lawnmowers; protectning the users from injury when using the lawnmower in slopes, and when cleaning the cutting blade.The task was carried out through initial studies on a representative lawnmower. A generation of ideas followed with an evaluation to select the best solution. The winning concept was further developed to reach acceptable performance. The word resulted in a functioning prototype utilising an original way of detecting inclinations without incorrect signals. It c an serve as a platform for further development into a product.The work gives insightful experience of solving real-world problems, and especially to deal with situations where several variables and their effects are unknownPlease note that several parts of the work are confidential, and have therefore been removed from the thesis..

Prediktering av skogliga variabler med data från flygburen laser : En jämförelse mellan multipla regressionsmodeller och k nearest neighbour-modeller

This study has the purpose of looking at the current and future position of record labels from a context involving the technological developments, while the opportunities for the artists are changing. As the actors inside them music industry find themselves in an ever changing climate where traditional supply chains are threatened by new technology, the record labels need to change the way they work in order to maintain their existence in the music industry. The study has been conducted by interviewing a number of people involved in the music industry, by using a qualitative method approach. The conclusion of the study shows that the traditional way of doing business by treating music as a product that makes revenue is gone. Instead the labels have to take on new roles formerly run by third parties in order to survive and be profitable, especially since artists can now in control of activities that used to be controlled by the record label..

Utveckling av biotopdatabas och tillämpning av landskapsekologisk analys i Huddinge kommun

På grund av ökad urbanisering och exploatering av grönområden i stadsnära miljöer fragmenteras och reduceras arters habitat vilket bland annat ligger till grund för den globalt minskade biologiska mångfalden. För att stärka och förbättra arters möjlighet till spridning i landskapet, och därmed säkra en hög biologisk mångfald, efterfrågas insamling av data och utveckling av nya metoder för att identifiera ekologiska kärnområden och för att analysera habitatnätverk. Syftet med den här studien är därför att 1) kartera och sammanställa biotoper i en biotopdatabas utifrån tolkning av infraröda flygbilder med digital stereofotogrammetri, 2) undersöka olika metoder att samla in data med hjälp av laser- och höjddata, och 3) att tillämpa landskapsekologisk analys på underlag i biotopkarteringen.Resultatet validerar att tolkning av infraröda flygbilder med digital stereofotogrammetri är en utmärkt källa för att kartera biotoper som medför en tolkningsnoggrannhet på 86 %. Valideringen av kateringen genomfördes med fältkontroller som utvärderades i felmatriser. En metod har även undersökts baserat på tidigare studier för att uppskatta busk- och krontäckning med hjälp av laserdata, men eftersom det saknas validering av resultatet bör den användas som en indikator för att visuellt uppskatta busk- och krontäckning i dagsläget.

Teoribildning och bildtolkning som metod för nytänkande : en studie av heteronormativa diskurser med utgångspunkt i konstnären Chaterine Opies fotografi Self-Portrait/Cutting

Syftet med mitt examensarbete är att belysa resonemang rörande normalt respektive onormalt, maktstrukturer, genusfrågor och kommunikationsprocesser, med utgångspunkt i konstnären Catherine Opies fotografi Self-Portrait/Cutting från 1993. Verket rymmer en komplexitet eftersom brottet mot våra heteronormativa föreställningar utrycks så explicit. Det finns en ambivalens och direkthet i verket som fascinerar. De motstridiga läsningarna väcker ett behov av att förstå bilden på ett mer nyanserat sätt. Jag har medvetet valt att studera Self-Portrait utifrån teorier som ligger till grund för många konstnärer som väljer att röra sig i gränslandet för det samhället satt upp som norm.

Downsizing : Hur överlevare av uppsägningar påverkas av upplevelsen

In today?s business environment, cost-cutting practices such as downsizing and layoffs remains a widespread phenomenon. Although, the understanding of the effects that these practices has on the remaining individuals, defined as the survivors, is poor. The focus in this paper is therefore to examine how survivors of layoffs can be affected on an individual level, and by what causes.The study was conducted using open-ended, qualitative interviews with three individuals with different experiences of layoffs. The empirical data was analyzed by extracting quotations from the interviews.The study found that layoffs affected the morale and attitude towards management of the individual, and that perceived justice and uncertainty are two causes of negative effects from layoffs..

Konstruktion av upprätningssystem för CICLoPE

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

Åkertistel : biologi och icke-kemisk bekämpning

A growing problem in Swedish herbicide free agriculture, the Canadian thistle has been the object of several new trials, seeking methods for non-chemical weed control. The new trials have mainly confirmed earlier experiences; that the most successful methods of control are springtime ploughing, repeated cutting and competition from a stout crop. Row hoeing has also been proven effective. As opposed to earlier recommendations, half season fallow has shown to be a risky and often ineffective method of control. Trials regarding biological methods have shown that above others thistle rust (Puccinia punctiformis) may have the potential of controlling Canadian thistle the future. .

Små vatten- och avloppssystem : Möjligheter till inskränkning av verksamhtesområden

This study is focused on small scale water and wastewater handling in Sweden. The study is divided into two major parts; the first describes common methods for water- and wastewater handling and the second part is a case study on three small and expensive systems in Gällivare municipality, in the north of Sweden. In the case study, abilitys for the local government to hand over unwanted systems to the water users is investigated and found to be a plausible solution to cut costs for two out of the three studied systems. In the third case, water and wastewater systems is not recommended to be handed over but other ways of cutting costs are suggested..

Strandfastigheters gränser : En studie av gränser i vatten.

Vattendrag och stränder graderades under 1700-1800-talet mycket lågt (impediment) då marken inte var odlingsbar. Samma mark är idag eftertraktad av människor för fritids- eller permanentboende i en lugn miljö. Problem kan idag uppstå vid gränssättningen av strandfastigheter som nybildas. Problemen är vanligen kopplade till var gränserna verkligen är belägna och var fastighetsägarna anser att gränserna borde vara belägna. För att bestämma var gränserna går måste lantmätaren gå tillbaka till ursprungshandlingarna för stamfastigheten och utföra en grundlig arkivforskning.Syftet är att undersöka hur gränssättningen utförs idag.

Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Flexibel ljudinspelning för talkvalitetsanalys

This report describes how wavefiles can be recorded with programs written in the C++ language . The report also describes how the recorded sound is handled before it can be analyzed. The report describes the different parts that make a wave file to a wave file and how Windows handle these files. There is always some silence or noise of unknown length that passes through the system before some interesting sound arrives. That silence or nose must not be recorded and therefore some function must be developed that can detect interesting sound or speech.

En analys av SCA Skog AB's metod för egenuppföljning av gallringar :

A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.
