To be a part of the future we have to make a profit, one way to improve the profit margin is by reducing the fixed costs. This paper discusses the financial results of equipment cooperatives in crop production. Through a case study of three farms in Södermanland, we have an example of how it can look today and how it could look tomorrow. The three farms are crop-producing farms with slightly different orientation. Jursta Gård, 155 hectares, and Djursnäs Säteri, 215 hectares, have grains crop and oilseed crops as the main crops, and Nibble Gård, 340 hectares, mostly have pasturelands and some grain crops.

Dancewalks är ett platsspecifikt danskonstverk skapat och uppfört i olika semioffentliga rum. Den här kvalitativa studien undersöker resultatet och effekterna av en Dancewalks i Malmö där 30 arkitekter och stadsplanerare deltog. Dancewalks är i sig själv ett performance vilket påverkar studien och därför också undersökningsprocessen. Det teoretiska ramverket utgår från Non representative theory och teorier om hur människor interagerar i rum. Tillvägagångssättet för studien är en triangulering av observation, fokusgrupp och semistrukturerade intervjuer.

Vid svåra tider har det blivit allt vanligare att företag outsourcar delar av sin verksamhet. Även om ansvaret för verksamheten faller på en annan part kan grundproblemet till varför outsourcing genomfördes bestå och fortsätta att påverka företaget. För att förhindra ett förhastat beslut om outsourcing, är det därför viktigt att ta reda på hur verksamheten presterar och kan förbättras. Av denna anledning är det av ytterst viktigt att företag mäter sin prestation. Genom att mäta prestationer övervakas företagets aktiviteter, processer och utveckling i önskad riktning.

Today, companies work with issues concerning Corporate Social Responsibility (CSR). A higher demand from customers and other stakeholders as well as an extended legislation are great reasons. Framework and guidelines for sustainability reporting has been developed which includes indices that companies are able to report. Though, for a long term work with sustainability a functional system and internal tool is necessary. Balanced Scorecard, BSC, is a useful tool and efforts have been made to integrate BSC and CSR with purpose to establish the work with sustainability in a more concrete and clear way.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

The aim of this essay is to answer the question of how ? in what ways ? Jeanette Wintersons Written on the Body and Sarah Waters? Tipping the Velvet are queer texts. My method is that of a thematic analysis, focusing on words and phenomenon related to definitions of the multi facetted term ?queer?. The analysis covers themes of lesbian focus, performativity, performance, speech-acts, and heteronormative and queer relationships.

Syfte och frågeställningar 1. Finns det ett samband mellan tiden mellan fotisättningarna (främre respektive bakre fot) och sparkhastigheten? 2. Hur påverkar bakre fotens kontakttid sparkhastigheten? 3.

I have examined the conditions for participation in an opera masquerade. Theoretical support has been found in Michail Bachtin, Richard Schechner and Judith Butler. The main study object has been a masquerade organised by the workers of The Royal Opera of Stockholm in 1925. The masquerade is examined as a social practise with distinct aesthetic framing. The analysis shows that the opera masquerade share some characteristics with the medieval carnival culture as described by Bachtin, but differ in many ways as well.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

This Degree Project was about finding the best loudspeaker placement in a heavyweight truck and also the best suited loudspeaker for this task. The project took place in Södertälje, Sweden, on behalf of Scania CV AB. The goal was to create a new listening environment in a truck cabinet.The results were accomplished by the performance of a few different tasks. First a benchmark was made on Scanias top competitors. Second a listening test was made to get an apprehension of what people find lacking in the sound reproduction of the sound system.

In this Master thesis, microwave connections between circuit boards are constructed. The primary frequency band is the X-band (8-12 GHz). The purpose of the connections is to enable a more simple and cheaper way of mounting the circuit boards inside a container. The connections have been designed and evaluated, using different computer programs. A few prototypes have been built and measured.

Denna uppsats vetenskapliga grund hämtas främst från ekofeminism med tanken om jämställdhetsarbetets samband med miljövård, samt närvarons politik med teorier kring representationens betydelse för den politik som förs. Ekofeministisk teori menar att det finns betydelsefulla samband mellan förtrycket av kvinnor, icke-vita människor, och fattiga på ena sidan och den icke-mänskliga naturen på andra sidan. Detta innebär att kvinnor på ett bättre sätt förstår det förtryck som finns mot icke-mänsklig natur än män. Teorin om närvarons politik menar att det styrande idéfokuserade politiska systemet går miste om viktiga perspektiv och kunskaper som en mer representativ politik kan ge. Närvarons politik utgår från att politiskt underrepresenterade sociala grupper kan bidra med perspektiv och kunskaper som annars förblir ohörda.

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.
