Mot en h?llbar framtid. Vilken roll kan metrobuss ha f?r framtidens mobilitet p? motortrafikleder i G?teborg, M?lndal och Partille?
Denna uppsats unders?ker hur inf?randet av metrobussar (Bus Rapid Transit, BRT) kan f?r?ndra motortrafikledernas roll inom G?teborgsregionens kollektivtrafiksystem, omfattande G?teborg, M?lndal och Partille (GMP). Syftet ?r att belysa planerares perspektiv p? metrobussarnas potential att fr?mja en h?llbar transportinfrastruktur. I en tid d?r h?llbara transportalternativ blir allt viktigare, utforskar studien hur metrobussar kan integreras i regionens befintliga system.
Undersökning av Mekaniska Problem med hjälp av Datoralgebra
When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..
Aurora - Technology made to make things easier
Det började faktiskt redan hösten 2004, när jag satt och arbetade med ett av de
otaliga projekt man gör under sin skolgång. Projektet gick ut på att skapa en
hemsida med en digital katalog, och voilá, där föddes idén.
Sedan fortsatte jag att fundera, vända och vrida på idén, ett system för att
skapa digitala kataloger och mindre presentationer som vemsomhelst skulle kunna
använda. Just detta att inte exkludera de som inte kan ?Flash? från de som
skall kunna redigera systemet har varit en av mina stora grundpelare, ett slags
digital demokratitanke.
För att skapa systemet har jag använt ?Macromedia Flash MX? och dess inbyggda
programmeringsspråk ?ActionScript?. Programmeringsspråket är inte ursprungligen
tänkt att användas för att göra system, men jag tycker personligen att jag
lyckats bevisa att det fungerar även för det ändamålet.
Analys av artificiella marktyper vid vatten med hjälp av GIS, Värmlands län 2007
On commission of the County administrative board in Värmland County a method was developed for analysis of the occurrence of artificial land use at lakes and watercourses. With artificial land use is meant land significantly affected by man. Two bases have been used to carry out the analysis. In one of the analysis the vegetation database and in the other GSD¹-Marktäckedata (land cover data) was used (this method has been used by County administrative board in Jönköping County).The analysis comprises all watercourses within Alsterälven river basin. The digital water bodies are created by the Swedish Meteorological and Hydrological Institute on the basis of GSD-Översiktskartan (general map).
Volymsrapportering vid terrängtransport av virke
This report is a B.Sc. Forestry thesis work at the school for Forest Management, SLU.
The work was an assignment from the forest owners? association Mellanskog.
The aim of the work where to investigate the economical result of removing undergrowth trees before first thinning, and a follow-up of the contractors and their compliance with Mellanskog standards.
This thesis work was divided in three parts: The first was to find a relation between the net volume from the first thinning and the cost of cleaning undergrowth trees. Secondly there was a follow-up in the field, to investigate whether the contractors have done the undergrowth cleaning according to Mellanskog?s directives.
Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.
Kommunikation med hjälp av mock-uper
In several cases, systems that have been developed have been very time
consuming and cost a lot of money, but they still do not fulfil the users
requirements and requests. To make new systems better, you have to find a way
to communicate that allows the developers to understand the needs of the user.
The aim for our thesis is to highlight the importance of communication in
system development. To investigate this we have choosen to do a study of the
real-estate system. The work methods that have been used include mock-ups and
informal conversations with the user, who is employed by the Church of Sweden
in Ronneby.
VVA-strategier för avgastemperaturhöjning på en HD-Dieselmotor
Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.
Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae
The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great
discomfort for the hens and effecting the production economically. Few efficient acaricides are available
and there is a need for new control methods since resistance has become a problem in some cases.
The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).
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.
Tre metoder för diagnos av mastit i fält :
The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings.
DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations.
Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.
Kommunikationsproblem på Apotek
The origin of the word ?communication? is the Latin word communicare, meaning to make common. The reason for our communication is to share thoughts, feelings and information, we want to affect and confirm.We are used to interpersonal communication, but even if we have had a lot of practice at it during our lives, we still find our selves facing misunderstandings and conflicts. The more people we meet during a day, the greater the chance is for interruptions in the communication.In pharmacy practice, good communication is vital for the client?s health and quality of life.
Tingsryds Travbana
Our bachelor thesis is a visualisation made in 3D-graphics of how the horserace
track in Tingsryd perhaps will look like in the future, complete with a
miletrack, steeplechase, and other horserace courses. Today, the race track is
only in it?s building phase. The inner field-group in Tingsryd needed
presentation material to show their eventual sponsors, so they contacted us at
Media Technology, and we instantly decided to give their idea a try..

Shaping visual stories - content in exhibitions is an essay on how content has been shaped in the two exhibitions "Memento mori" and "Hästen - tyglad, piskad, älskad". The study focuses on how exhibitions can be defined through their content as well as how the exhibitors'different intentions towards the exhibition affect the working process as well as the result. This is put in relation to theoretical models and discussions on ideals in the field of exhibition and what impels these to find an answer to the question: What makes an exhibition?.
En kvalitativ studie om hur personer med utländsk bakgrund upplever att integrationen fungerar i Sverige
Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.
