Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.
Våtmarker i urbana miljöer : växtgestaltning och planering
The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability.
Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do.
The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.
Ultraljudsmätare för bubbelfälla
This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.
Teknikämnet i grundskolan : Idag och imorgon
Detta arbete har två olika delar som behandlats på olika sätt. Inledningsvis har dagssituationen för teknikämnet i grundskolan kartlagts. Bland resultaten återfinns ett samband mellan behöriga tekniklärare samt de lärare som själva valt att undervisa i teknik, och intresset för ämnet teknik. De behöriga tekniklärarna återfinner vi framförallt i de större städerna. I den största gruppen lärare som undervisar i teknik, No lärarna, har endast tio procent valt att undervisa i ämnet själv.
Tillgängliggörande Vs Distribution : Är en skiva en skiva om den enbart finns digitalt?
The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.
Professionell garantihantering : Ett arbete inom byggnadsbranschen
A business is always dependent on its customers. It is therefore important to ensurethat customers are satisfied with the product and the warranty included.The study was conducted in cooperation with the building contacting companySkanska Sweden. The aim is to use interviews to collect and process experiences in order to answer the question: How should the recovery process in the construction industry be performed to ensure a professional handling of warranty? The results have shaped my conclusions and I have turned them into a proposal that companies in the industry can benefit from. The study indicates that the industry is not geared for a five year warranty, which was introduced in 2004 and 2006.
Den nya generationen: Dystopisk reproduktion : En tematisk genusanalys av Karin Boyes Kallocain, Aldous Huxleys Du sköna nya värld och George Orwells 1984
The three dystopian novels Brave New World by Aldous Huxley, Kallocain by Karin Boye and Nineteen Eighty-Four by George Orwell have been highly discussed amongst literary critics and scholars. Although these works are well-known, some themes have had very little or no recognition. Biological reproduction is a recurring subject in dystopian literature. Although it is not the main theme in the novels, it is a very important part in dystopian culture and dystopian society. By focusing on reproduction and the structure of gender roles in these three dystopias, I hope to bring to light something that's been in the shadows for a long time i.e.
Projektledning i virtuella teams - Förtroende, gemensam förståelse och groupwares
Virtual teams are teams where team members don?t sit and work in the same place, they canwork in different countries, cities and buildings. It?s not the distance between team members that defines a virtual team, it's the extent to which the team is dependent on information technology to communicate and carry out a task. Virtual teams is becoming more common in organizations, to use virtual teams organizations can reduced time and travel costs and create a larger knowledgebase.A project manager for virtual teams faces many challenges, they have to build trust with and among team members they rarely or never meet, create a common understanding of project objectives and manage the challenges that culture and information technology creates.
Ansiktsigenkänning somidentikationsmedel; frånvision till färdiginpasseringsprototyp
Det FInns många typer av identikationsmedel och i denna rapport redovisas uppbyggnaden av en prototyp som använder ansiktsigenkänning för identifiering vid en dörr. Prototypen är ett resultat av ett examensarbete på företaqet Wawo Technology AB och författarens roll i projektet var som projektledare. Projektledarens fokus låg på kommunikation med teammedlemmarna, på att driva projektet framåt samt på att användartesta systemets alla delar. Resultatet av projektet blev en prototyp som i dagsläget är monterad på ett kontor och används av personalen. Registreringen till systemet sköts viaen hemsida av en administratör.
Omfattande animationsarbete i 3D-miljö
Med ordet 'omfattande' försöker vi indikera att projektet har inkluderat de
flesta aspekter som arbetas med i modern 3D-animerad film. Vi har grävt ner oss
i begrepp så som modellering, texturering, UVW, benriggning, skinning &
morphing varav alla har spelat in en viktig roll vårat animationsarbete..
Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS
This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.
Framtagning av en rörväxlaretill sopsugsystem
The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.
Visuellt berättande i spelmiljöer
Abstrakt
I den här uppsatsen undersöks hur ett narrativ kan drivas inom digitala spel
enbart med hjälp av spelmiljön. Syftet är att få förståelse för vad
miljöberättande behärskar som en självständig form av berättande och vad
författarna kan göra för att uppnå detta mål. För att undersöka problemområdet
genomfördes en spelproduktion där metoder framtagna under undersökningens gång
applicerades. Produktionen testades av utomstående studenter i medieteknik och
resultaten sammanställdes med reflektioner kring vad som uppnåtts och de
metoder som applicerats. Undersökningen beskriver arbetsprocessen och metoder
och visar hur dessa kan driva ett narrativ med en spelmiljö.
Abstract
In this thesis examines how to drive a narrative in digital games using only
the game environment.

Förlustsänkning i drivlina : En simuleringsmodell av hjulaxel till anläggningsmaskiner
Med ökad fokus på miljöpåverkan och bränsleekonomi vill Volvo Construction Equipment öka verkningsgraden på sina anläggningsmaskiner. På avdelningen för drivlineutveckling jobbar man bland annat med att sänka förlusterna i växellåda och hjulaxel på hjullastare och dumper. För att underlätta detta arbete har en simuleringsmodell som beskriver förluster i hjulaxlar tagits fram. Denna rapport beskriver framtagning av modellen, verifiering av modellen och vilka framtida användningsområden modellen lämpar sig för.Simuleringsmodellen är uppbyggd av ett antal komponentmodeller. Komponentmodellerna innehåller formler för respektive komponent i hjulaxeln.
