Övertoner orsakade av varvtalsstyrda motordrifter ger problem i industrisystem. Syftet med studien är att identifiera problemen och ge rekommendationer för att undvika dem. Studien utfördes som examensjobb på KTH för konsultföretaget Ramböll. En litteraturstudie i ämnet kombinerades med elkvalitémätningar på drifter hos Sandvik Mining.Elkvalitéproblem orsakade av varvtalsstyrda motordrifter kommer till stor del av att frekvensstyrningen ger olinjärt strömuttag som, om nätet inte är tillräckligt starkt, påverkar spänningskvalitén. Problemen kan vara driftstopp, störd utrustning och ökat slitage på utrustning för att nämna några.Denna studie visar att vid ändringar i system innehållande övertoner kan framtida övertonshalter approximeras för vissa fall.

To be competitive in the corporate climate of today it is important to have effective logistic activities. A common resource within the internal logistics is forklift trucks, which are used to lift and transport material. It becomes more and more important to decide whether to buy, lease or rent the forklifts to obtain an optimal economic situation. Many companies have issues with internal pricing. It is difficult to price products and services correctly. It is common to price the overall instead of what it really costs.The purpose of the thesis is to present a model for the acquisition of forklifts for internal logistic operations, regarding financing and internal pricing, to obtain economic effectiveness and an optimal forklift fleet size. The study focused on a specific research question, and for this purpose interviews with experts were held, observations were made and a literature study was done.

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Testing and analysis of measurement data is a major part of the workday for development engineers within the section Fluid and Emission Treatment to assure the quality of products developed by Scania CV. The ineluctable variation and therefore uncertainty of results can be quantified and discussed with the use of statistical methods.The overall objective of this study is to examine how the competence of development engineers can be improved within the area of statistics. This has been done by relating the concept of competence with the use of statistical methods to analyse experimental data and by investigating which factors that influence the competence of the engineers. Observations of the daily operations, interviews and a focus group with development engineers and a workshop with management personnel, has been used as research methods in this study.The results show that the desired competence, from the perspective of the individual, consists of knowledge, motivation and support. It is important that none of these parts are neglected when the competence of engineers is to be strengthened.

Since the 1st of May 2004 Cyprus is part of the European Union. The Republic of Cyprus as a whole is part of the Union, but all of the advantages of the Union membership cannot be enjoyed in all parts of the country. Since December 1963 the Cypriot administration has been separated into two, a Greek Cypriot and a Turkish Cypriot, and since 1974 the country is also territorially divided. The Greek Cypriot political administration is considered to be the legitimate representative of the Republic of Cyprus, the Turkish Cypriot administration is only recognised by Turkey. Since the disruption of the country in 1963 the UN has been trying to get the Cypriot parties to agree upon a peace solution in order to reunite the country.

Abstract Considering the social dimension of sustainable development this thesis focuses on the qualities of life and how the environmental qualities that the inhabitants value can be incorporated in the physical planning of the municipality. The thesis deals with the problems that occur when the physical planning, whit its focus on the environmental aspects, also needs to consider peoples opinions, that springs from the individual experience of the place. The municipality of Mark, where this thesis takes its place, is characterised by the countryside landscape. Mark is situated in the western part of Sweden close to Göteborg, Borås and Varberg. The commuting is extensive and the demand for dwellings in the municipality is increasing. Those who strive to live in the municipality have a conception of what life on the countryside means and of which environmental qualities they want to assimilate.

The State Institution for Education of Feebleminded Girls was one of the two swedish educational institutions established under state management in the 1920s and came to be the starting point for further government operations for the mentally deficient. The purpose of this paper was to investigate the activities of the State Institution for Education of Feebleminded Girls, out of what needs the institution filled in Sweden?s care for the mentally deficient. The institution has tried to be understood from the view of eugenics and the perspective of children that was current during the 1900s first half.To fulfill the purpose of the study, the archives for the State Institution for Education of Feebleminded Girls was studied and analyzed with basis of previous research on Sweden?s care for the mentally deficient and the impact from eugenics and Sweden?s child perspective.The study shows that the State Institution for Education of Feebleminded Girls mostly existed to educate students and adapt them to the community, which the institution did by education, disciplinary interventions and sterilizations.

Syftet med denna uppsats är att bidra till ökad förståelse för vilka utmaningar svensk flygstridsledning stårinför i utvecklandet av en internationellt fungerande flygstridsledning. Begreppet interoperabilitet har inledningsvisbeskrivits ur Försvarsmaktens perspektiv för att därefter ges en vidare tolkning genom MichaelCodners teorimodell. En enkätundersökning ställd till flygstridsledare visade att de viktigaste faktorer förinteroperabilitet på stridsteknisk nivå inte överensstämde med militärstrategiska nivåns tekniska fokus förinteroperabilitet.Flygstridsledarnas identifierade faktorer, stridsledningsteknik samt luftrumsprocedurer, utnyttjades vidare isyfte att klarlägga skillnaderna mellan svensk och brittisk flygstridsledning, samt hur dessa påverkar möjlighetenatt uppnå svensk interoperabel flygstridsledning. Analysen visar på avgörande skillnader mellansvensk och brittisk flygstridsledning. I huvudsak kan dessa skillnader hänföras till kulturella och beteendemässigafaktorer.Avgörande för att utveckla en interoperabel svensk stridsledning är tillgång till fullständig och aktuell dokumentationavseende taktik, metoder och procedurer, för både flygstridsledare och piloter.

This paper aims to find out how to implement an information security management (ISMS) system that is based on ISO/IEC 27001-standard into a small organization with high employee turnover. The standard employs the PDCA-method as a course of action for implementing the standard. The reason for implementing such a system is to introduce information security to the organization and to maintain it despite the changes in management. The paper based it?s survey on a case study of a student nation in Uppsala, Sweden.

Internet has since the beginning of the nineties gone through an enormous growth in size, and with this big increase in numbers of users, a new, lucrative advertisingmarket was created with webbased marketing. This market has grown in the same tempo, and has now reached some sort of a breakpoint. There is no doubt that internet will be a marketingmedium to count on in the future, but how will development continue to progres and what shape will it have? Will this development keep on growing in the same tempo as earlier or will we see factors that put a break on this development?With this study, I have wanted to give a picture of internet as a marketingchannel today and how it is understood by consumers, spokesmen for the bransch and branschauthoritys. Further, I have tried to give a picture of how the future could look like, judging from the data that was collected from interviews, a big poll and those written sources on the subject that are available today.To be able to give answers to my questions at issue and reach a conclusion for the partproblems that I had initially, I have made a group of interviews with spokesmen of the bransches marketing, netportal, netanalysis amongst others.

This study aims to analyze the effects of the proposal regarding mandatory reporting for undocumented individuals within the Swedish public sector and how this potentially affects leaders in their efforts to motivate their employees to comply with this requirement, which is considered ethically charged. The primary focus is to understand how these leaders can motivate their employees considering legal requirements that are both legally binding and ethically sensitive. By interviewing leaders from various sectors within the public domain in multiple Swedish municipalities, this case study seeks to highlight the challenges arising from the amalgamation of legal mandates and ethical dilemmas. Its goal is to provide insights that can support these leaders in their complex decision-making regarding such issues. The study addresses theoretical aspects such as change management and critical organizational theory. The study's findings indicate that political decisions play a pivotal role in the processes of change within public operations. Resistance to change varies and takes various forms.

For Swedish companies to compete with low wage countries, developments in theproduction industry moved towards streamlining the entire company. One of themost effective ways for a company to streamline their operations is to review theirproduction. All companies have processes in their production that add no value tothe product. In order to compete, they must be eliminated.The purpose of this report is to reduce work in process (WIP) in the flow ofbashus at Volvo Powertrain in Köping. The aim is also to try to find reasons whyVolvo Powertrain feel that they have problems with the storage principle First in-First Out (FIFO).To meet the objective, empirical studies were conducted at the company whilethe literature in the area was studied.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.
