Utveckling av dynamiska farthinder
The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
Försäkringskassan- effektiv och/eller rättssäker?
The public administration and its officials have a number of values which they have to relate to in their work. The values are a set of democratic and economic values.This study?s purpose is to examine how the officials at the National Insurance Office in Sweden give priority to these values. The study is performed by interviews with officials at two insurance offices.The study shows that the officials in a high degree value the democratic values legal security and public ethics. In turn they experience that productivity, which is an economic value, is being promoted in a high degree from the management.

Method: Our approach is quantitative, using empirical data summarized in a statistical procedure. The result is thereafter analysed through the developed analysis model from which conclusion is drawn. Results: We have in the investigation stated that the usage of the cash flow statement report varies depending on the time perspective in which companies? acts.
Sociala medier och skolbibliotek ? En användarundersökning av efterfrågan av sociala medier på ett skolbibliotek
The purpose of this study is to examine the role social media canplay in a school library context, based on a theoretical model,called ?A new model for the public library in a knowledge andexperienced society? by Henrik Jochumsen, Dorte Skot-Hansenand Casper Hvegaard Rasmussen.The bachelor thesis aim to answer three research questions, theyare as follow: Which request of social media is there by teachersand pupils at a high school library? Which social media is the mostrequested by teachers and pupils at a high school library? Andshould the library services for teachers and students be improved ifsocial media were used at a high school library?The methodology used for this study was an inquiry investigation.My findings are presented in a context of previous, relatedresearch and the study shows that teachers and pupils are wellinformed of what social media is and they use social media whenthey are at school.The thesis also shows that the unit I study, a vocational trainingunit, is more or less interested in what the school library can do forthem with social media.They seldom are at the school library and they seldom use theteach platform were they can find library services.This result can open up for the school library to meet the users at anew arena with for example social media..
Kritiska Prestations Indikatorer (KPI), Hur väl fungerar KPI:er som verksamhetsstyrning inom den producerande industrin?
The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.
Identifiering av gallringsbehov med hjälp av flygburen laserskanning :
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.
Droppbevattningens inverkan på kvalitet och kvantitet hos Solanum tuberosum L i jämförelse med konventionell spridarebevattning :
A literature study and a field trial have been carried out in order to investigate the physiological response of potato plants to different soil moisture levels. Higher yield, quality and number of tubers can according to the literature be obtained if constant high soil moisture is kept during major parts of the growing season. A field trial was set up where drip irrigation was used as an alternative to conventional irrigation techniques to maintain high and constant soil moisture. The application of water in the drip irrigated area was monitored and adjusted on a daily basis so that the soil moisture stayed as close as possible to the recommended level. The sprinkle irrigated area was irrigated according to traditional practices with approximately 35 mm every 7th to 10th day depending on the whether.
När kommuner hänger med : En kvalitativ studie av hur åtta svenska kommuner har organiserat och använt sig av sociala medier i den egna verksamheten när det saknats officiella riktlinjer för detta
Title: When municipalities are keeping upAuthors: Hansson Käll, Ida; Jonasson, MikaelaTutor: Waks, CarolineCourse: Bachelor thesis, 15hp, Department of Business Studies, HT 2010Background: During the recent years social media has evolved into a powerful communicative medium. From an organizational standpoint social media has become a way for organizations to get closer to, and create a dialogue with, their environment. Swedish municipalities have began to use social media in their daily communication with the environment, but a problem has been raised about how public organizations should organize their social media when formal guidelines from the government are missing.Objective: The objective of this thesis is to examine how eight Swedish municipalities have organized their use of social media due to the lack of official guidance from the government, and also what difficulties that have occurred during this process.Method: The method used is qualitative with data collected through interviews with one respondent from each municipality.Results: The result show that the organizational solutions varies through each municipality but also the choice of social media. It has been important for municipalities to have someone in charge of the new communication tool since social media is a fast and communicative channel. Seven out of eight municipalities have already developed or are in process of developing their own formal guidelines on how to use social media.
Evaluation of tools for analysis and quantification of Fusarium mycotoxins
Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.
Lövsuccessioner i sluttningar längs nedre Umeälven :
Secondary deciduous forests, which have their origin in earlier pasture- and meadow-land in slopes along the lower reaches of the Ume river, are thought to contain high nature conservation values, in spite of a relatively low age. The aim of this study was to clarify how factors as historical use, exposition, disturbance dynamics and successional age influences the conservation values in these types of riparian forests and how this can be implicated in the practical work with conservation and management at Umeå municipality. Sample plots were placed in seven stands with a variation of their historical use, exposition, disturbance dynamics and age of succession. Conservation values as structure, tree-regeneration, abundance and composition of vascular plants, amount of dead wood and the abundance of signal-species were measured and registered. The species composition and especially the composition of tree species, differed between forests with different exposition and different historical use.
Mellanskogs medlemmars syn på röjning
The main purpose of this study is to investigate the needs of pre-commercial thinning on private owned forest properties, which is considered to be increasing. The reason is believed to be the high cost of labor that pre-commercial thinning brings. Furthermore thinning is costly, the revenue created through pre-commercial thinning are post-poned until the first thinning.
The study was made through a survey among members of Mellanskog forest owners association. The survey was distributed by e-mail. The time to answer was set to two weeks.
The answers indicate that the most common reason why the pre-commercial thinning is delayed, or not done at all, is the forest owner?s lack of time.
Krukväxter med mervärde till dagligvaruhandeln :
The supermarkets are taking more and more market shares for potted plants the last years, and a greater part is bought without prior planning. Signals from several European countries, for example Denmark and UK, indicate that potted plants with added value have become more and more popular and the added value is based on present trends. The meaning of added value in this thesis is fancy pots, packaging, pins or arrangements. Potted plants with added value sold in supermarkets offer the consumer the advantage of getting a ?ready product? quick and easy.
Användare och användning : av information och handlingar i moderna polisorganisationer
This study examines use and users of information and records originating in the context of a contemporary police organisation. This area of research has only been of focus for a relatively few researchers. This in contrast to use and users of historical archives which has been in centre for more studies. The study is conducted with a quantitative method structuring data from 120 selected registered matters containing user queries. The research questions addressed are:- what user categories use the records of the authority- which are the ways of contacting the authority preferred by the users- which are the identifiers provided by the users and how well are they matched by the search artefacts available to the staff of the authority- what information and records are sought-after by the users.For comparing the identifiers provided to the search artefacts has been selected the two most frequently used registry systems within the authority.
Miljöledningssystem i små företag : vilka hinder finns och hur kan förenklade miljöledningssystem överkomma dessa?
Humanity?s increasing consumption has resulted in an increasing use of resources and thus an increasing environmental impact. Hence, the environment has become an important political issue. The increasing demands from stakeholders on companies to "green" their products and work internally with environmental issues makes it more and more important for enterprises to address these issues. Small enterprises constitute the majority of all enterprises and therefore they have a significant impact on environmental problems.
