Släpslangspridning av gödsel, kan det löna sig? :

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

`Hard eller soft power´ - när det gäller att främja demokrati och mänskliga rättigheter?

The thesis investigates how two of the world?s most powerful international actors, the US and the EU want to promote democracy and human rights. The aim is to compare how the US and the EU work in order to support a democratic development in the world. In order to fulfill the purpose of the thesis a qualitative text analysis was used. Since the aim is to compare the US and the EU I believe this method is beneficial.

Testbänk för motorbåtsdrev

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Övervakningssystem för båtelektronik

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

Musik och Livsstil : En studie om ungdomar och hårdrock

In the following study I probe the social world of hard-rock music. By conducting interviews with four young male enthusiasts of this music I try to develop a general picture of this social world, as well as of the basic elements on which this particular subculture is constructed. The identity of a hard-rocker is based upon a number of factors beyond just a preference for that music. Throughout the interviews I encountered many implicit norms that one must followed in order to be able to see oneself as a true hard-rocker. I also found that from the respondents? perspective, the mainstream culture has, throughout the history of metal music, used various ways to counter the spreading of this genre.

Det är dags att komma ikapp!: En kvantitativ studie av vad som påverkar fotbollssupportrarnas intentioner att konsumera ett varumärke

The study examines what affects loyal football supporter?s intentions to an array of behaviors that can generate revenues to the football clubs. Specifically the study shows that attitude towards the club affects the supporter?s intentions towards consuming products and services that in some way are related to the favorite club stronger than the satisfaction with the club. Furthermore, the study also shows that there are different kinds of attitudes that drive the intentions and that the strength of these drivers varies.

Energieffektivisering på Skutskärs Bruk : Varvtalsstyrning till utvalda pumpenheter på Blekeri 4

In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK.

Markägares val av skogspartner :

Derome Skog AB is a purchase company whose main task is to provide Derome Timber's sawmills in Halland with timber raw material. Because of the very hard competition in the roundwood market it is important to know what kind of purchase offers are required in order to buy a valuable product from forest owners.This study aims to elucidate the crucial factors when private forest owners choose to harvest and sell their forest. As base for this study, a questionnaire has been performed with private forest owners. The result of the study shows that it is not particularly often that the timber price is the crucial factor why the forest owners choose to harvest and sell the forest products; i.e. timber, pulpwood as well as energy assortments.

Hybriddrift i stridsfordon, fördelar och nackdelar

Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.

Mätningar av statiska och dynamiska egenskaper för bakaxel.

To design new and high tech products the engineers rely more and more on computer based simulations to investigate the properties and behavior for a component or system.To verify these computer based simulations the dynamic properties for the components of the drivetrain needs to be verified. Therefore measurements of the stiffness and vibrations for the rear axle has been performed. This report show how the measurements has been implemented and evaluated, along with some interesting results for the rear axles properties.The static stiffness for the drive shaft along with the axle-gear has been determined. It is found that the stiffness for the whole rear axle is near the stiffness for the drive shaft, which means that the drive shaft becomes the dominant component of the system and affects the rear axle stiffness the most. The measured stiffness of the driveshaft is close to its theoretical stiffness.The stiffness for solely the hypoid-gear have been calculated using the stiffness for the rear axle and driveshaft, and thus has a range for the stiffness of the hypoid gear been determined.The backlash for the whole rear axle and for some individual components has been determined, where the backlash between pinion and crown-wheel has negligible impact on the total backlash.Measurements of the crown-wheel and pinion movements have been conducted, where the direction of movement is consistent with the theoretical direction of the forces.The vibration measurements show that the vibrations are more severe at certain rotational speeds.

BESTRAFFA ELLER BEL?NA? En kvantitativ studie om milj?politik och v?ljarbeteende

A possible explanation for the inability of the governments of the world to implement necessary environmental policies is that they are worried of being punished by voters for implementing too forceful policies. But do voters actually punish governments that implement more stringent environmental policies? Few studies have explored this question directly. Parts of the literature on environmental policy and public opinion indicate that voters would predominantly reward governments that implement more stringent environmental policies, while other parts indicate that voters would predominantly punish them. It is also possible that voters punish governments that implement more stringent environmental policies in some contexts, but reward them in others.

Finanskrisens påverkan på attityd till förvärv av förvaltningsfastigheter

Under de senaste åren har teknologiska förändringar medfört att banker ändrat utformningen av sina tjänster. Pengar har digitaliserats och individer har minskat användningen av kontanter. Flera banker har avvecklat den manuella kontanthanteringen över disk och erbjuder kunderna alternativa tjänster som exempelvis internetbank och kontokort. En del upplever nytta och nöje med tjänsterna, medan andra möts av svårigheter som gör att de inte använder dem. När en bank genomgår förändringar är det viktigt den tar hänsyn till kunderna för att behålla dem vilket leder oss in på studiens problemformulering: Hur ska en bank hantera sina kunder när organisationen avvecklar den manuella kontanthanteringen över disk och erbjuder alternativa tjänster? Huvudsyfte är att, genom en studie av Swedbank, skapa förståelse för hur relationen mellan bank och kund påverkas av förändringarna.
