Kartläggning av markberedning i svår terräng på SCA Skog
Due to the requirement for reduced use of insecticides and the lack of competitive mechanical plant protection, you need a scarification with good result. This is often no problem to perform in normal terrain without technical barriers. However, in difficult terrain with large number of rocks and steep slopes, the result would be worse. The purpose of the study is, that in these areas with difficult terrain, to find out the scarified areas quality, describe the non-scarified areas conditions and find out where the limit is for the use of a traditional disc trencher. Findings indicate that there are usually not the machine that is the limit, but the driver of this.
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.
Vi tar tempen på ert CO2-utsläpp! : en studie av hållbarhetsredovisningars användbarhet
The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.
ARBETSLEDARROLLEN - UR ARBETSLEDARNAS PERSPEKTIV
This bachelor thesis is intended to point out differences within the supervisors? role and contribute in making the role more attractive.

Mjukvaruplattform för riggstyrning
Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.
RISKfree ? ett system för riskhantering inom programvaruprojekt
RISKfree ? ett system för riskhantering inom programvaruprojektI dagens IT-centrerade värld sker utvecklingen av hårdvara och programvara i en rasande takt. Om ett företag skall ha möjlighet att vara konkurrenskraftigt i denna utvecklingstakt, krävs det snabba och effektiva metoder i utvecklingsprocessen. Dessa krav från omvärlden på nya och mer komplexa produkter och tjänster innebär ofta nya och större risker för ett utvecklingsprojekt; både ekonomiska som tidsmässiga.Analyser av programvaruprojekt som har misslyckats visar att många av deras problem och risker kunde ha undvikits eller åtminstone drastiskt reducerats med hjälp av riskhantering. Oftast är det en optimistisk entusiasm över projektet som överskuggar viktiga varningssignaler om risker och problem enligt B.W.
Organisering av ojämställdhet - En studie av kvinnors möjligheter att nå chefspositioner i Försvarsmaktens personalstab
This thesis aims to examine why women are prevented from attaining high positions in organizations. By executing a case study through qualitative interviews with employees from the Human Resource Department at the agency for Swedish Armed Forces, this study presents eight general and specific explanatory factors that hinder women from making a vertical career. The general factors include that women are discriminated against, women are perceived as less competent, men have created organizations and it is easier to recruit men. The specific factors include that a hierarchical organizational structure is correlated to inequality, that both the agency for Swedish Armed Forces and leadership are associated with masculinity and that women with civil competence face double misfortune. The division between general and specific factors indicate that the explanatory factors vary between organizations, which among other things implies that equality work should be tailored for the specific organization.
Vattnets väg genom ett romerskt bad. - tekniken bakom marmorn.
This essay focuses on the technical systems and functions behind how a Roman bath operated. I will present a general view by going through each part of the waters path through the bath one by one. Since there is no such thing as a standardised Roman bath I will, under each headline, present the sub subject with a presentation of the workings and then exemplifying through archaeological findings and ancient literary sources.This essay is therefore meant to present a thorough and clear presentation of the technical aspects of a roman bath. The aim is to give the reader an understanding of how a bathhouse worked in general and why. To this I want to present problems that the Romans were faced with and how they solved them..
Digital Airsoftstyrning : DAC Mark.I
The Airsoft Community always search for realism and optimal performance.When the performance and/or the realism in your AEG1 aren?t enough you turn to modifications toimprove the weapon. But to manufacture such modifications isn?t that easy, hence you turn tocompanies that are specialized in creating such devices.The goal with this project is to create a prototype of a modification called ?Programmable MOSFET?and targets optimization of the electrical components within the AEG. This means that you digitalizethe control of your AEG thus entails new functions and more stability to the system that isn?t possiblewith its mechanical predecessor.A prototype has been manufactured and programmed with functions according to requirementspecificationsthen it was tested on an airsoft-gearbox with rewarding results.
Elektronisk signering ? Kommer användaracceptansen att påverkas inom 24-timmars myndigheten?
Utvecklingen av medborgare samt företags användande av Internet har ökat
dramatiskt under de senaste fem åren. Det ökande Internetanvändandet ledde till
att statskontoret 1999 fick i uppdrag av regeringen att ta fram olika förslag
samt underlag som skulle ligga till grund för begreppet 24-timmars myndigheten.
Tjänsten är beräknad att tas tillbruk i Sverige år 2005. 24-timmars myndigheten
kommer tillämpa ett antal olika säkerhetslösningar, därav elektronisk
signering. Denna utredning skall belysa hur stort inflytande säkerhetslösningen
elektronisk signering kommer att ha på användaracceptansen av denna tjänst.
Ungas psykiska hälsa i form av hanterbarhet : En kvantitativ studie utifrån ett genusperspektiv
The aim of this quantitative study was to from a gender perspective understand and measure the mental health among young people as a sense of managing to handle situations and also how satisfied young people are with their personal qualities. The study also aims to see if there is a connection between these two ways of explaining mental health. This study takes its standpoint from a gender theory and gender stereotypes. The study was conducted as a survey with 100 young girls and boys, all of whom was students of a Swedish upper secondary school. The result of the study show that young people in general has a good sense of being able to handle situations.
Elevprestationer och lärstilar : En intervju- och observationsstudie i matematik med lärare i år 4-6
This study investigates the teaching strategies of four teachers, and determines which teaching strategies give better results in mathematics at the middle school level? Result here means the knowledge level of the students. The result has been measured through leave out a mathematical test, which I leave out designed. Teaching strategies have been assessed through interviews with teachers and observations of their lessons.My study shows that to go through the lessons thoroughly in the traditional way, and open discussions with the whole class are best for students achievements.The information available, however, is too limited to draw some general conclusions, but my study can be seen more like a counter-example to the general praxis that is short lectures and individual assessment with one to one communication when teaching mathematics..

Konstruktionstudie av en ångexpander
This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.
