Young stands in urban forests often lack a shrub layer, though shrubs play an important structural and biological role in forests. All layers interact with one another to form a multilayered stand, in which shrubs have a vital role.In this diploma thesis, theoretical models for forest dynamics are compared with four reference stands to detect factors, and principals for introduction of shrubs in young stands. In these stands four different ways of introduction were found. In one trees and shrubs were planted together at the same time. Shrubs spontaneous spread under a canopy of mature forest, in another.

The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

This paper investigates the automatic stabilizer and the underlying factors behind its function. The paper includes both a literature review and an empirical analysis. The literature review discusses the IS-LM and Mundell-Fleming models and different ways to quantify the automatic stabilizer. Based on the theory, the relationship between volatility in GDP and the size of the automatic stabilizers is then analyzed with the help of regressions. Our main result shows a negative relation between these two variables.

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

Do ceramics have to be static? This was the question that spurred me into this work, and what kept me working on to achieve the possibility of motion in my ceramic objects. By combining the knowledge gained through my former education as an avionics technician with my interest in the ancient ceramic craft, I strive to create kinetic ceramic handicraft suitable for interaction with an audience.By a series of different phases I slowly go from understanding what kind of motion I want my objects to have, to actually realizing this motion in three-dimensional objects. Through the use of simple models made from corrugated fiberboard followed by more advanced plaster models, combined with different complementary materials such as bicycle inner-tubing and recycled aluminium cans among many others, I, through a vast series of testing, slowly build up a knowledge base later applied to the ceramic objects.The result is for me a success; I have found a way for me to combine ceramics with mechanics. Through this I have created kinetic ceramic handicraft intended for interaction with an audience..

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

This report is a hermeneutic analytical study of a practical pedagogical situation. For three occasions I observed my own practice as a dance teacher and how a moment, choreographic approach in the governing documents for upper secondary school GY11 was executed in a group of dance students. The part is formulated in the course objectives for the courses on the arts program under the topic Dansgestaltning with focus on choreographic approach. The study is based on a socio-cultural thinking but also takes into account the prevailing gender theories and focuses on how the process of formulation level, through the transformation level is portrayed in the realization level of the dance regarding choreographic approach. The study illustrates educational research from both a dance perspective and a school development perspective.

Purpose: The purpose is to research different co-operations between venue owners and WISPs, when WLAN is deployed in a public space. The aim is to establish viable business models for the interaction between the two vital actors in the public WLAN industry. In this work, the advantages and disadvantages of revenue and cost sharing will be defined, along with technical and commercial issues that need to be resolved. Methodology: A number of case studies of the current situation have been conducted in the most attractive venues for WLAN, airports. As the public WLAN market had most widespread adoption and is most mature in the USA, case airports were chosen both there and in Scandinavia.

AbstractThis is a thesis done in cooperation with the firm Somas and University of Karlstad. The project is an independent final examination part of the program in Innovation and DesignEngineering comprising 22.5 points, and performed by Mia Myrén Zreloff during spring term 2012. In parallel and collaboration, Fredrik Kjellin performs a similar job for the same company and with the same extent, but for the Program in Mechanical Engineering.The client and supervisor at the company have been Magnus Jansson and Anders Josefsson. At Karlstad University has technical supervisor been Hans Johansson, and in the design- and development process it was Monica Jakobsson. Examiner has been Fredrik Thuvander, professor in the Faculty of Technology and Science at Karlstad University.The mission has been to make a basis work for the company's own development and make a computational model to calculate, visualize and implement materials and other solutions in the manufacture of the company's ball valves.The project has undergone three major phases that included thorough study of the company, production, the problem and product.

The purpose of this Bachelor thesis in Economics at Lund University is to try to establish the correlation between the value change of retail real estate buildings in Sweden and macro economic variables. The principal method is the multiple regression model and it is used to estimate the basic model. The basic model is enhanced by estimating some 30 models and the result is two good models. The difference between the basic model and the two better models are small but important. In the lagged basic model, the same variables are used as in the basic model but with different time lags.

The purpose of this master thesis is to examine the opinion about school libraries among principals at the independent schools in the municipality of Lund. In order to fulfil my purpose I used a qualitative method with an introductory questionnaire, which gave background material to the interviews. All seven principals answered the questionnaire and five of them agreed to participate in an interview. Another two interviews were made with two informants, this material was included in the background material. As theoretical framework I have used literature about the school library development, the role of the principal for development and David V.

This thesis concerns how local governments use the concept sustainable development, and what the concept means. The concept of Agenda 21 and local Agenda 21 will also be discussed in this essay, because it's an instrument for local governments to specify their work towards sustainable development. I have interviewed civil servants in leading positions in the municipalities? work with environmental questions and sustainable development. In the choice of method for this thesis, I use the qualitative method and for the interviews I chose the ?semi structure way of interviewing?.This thesis shows that local governments? implementation of sustainable development and Agenda 21 differ between the municipalities.

Uppsala universitet The aim of this master?s thesis is to investigate, through text analysis, the role of copyright in development, with particular interest of how the concepts knowledge and access to knowledge are used in Access to Knowledge Draft Treaty and WIPO Development Agenda. The definition of the concept knowledge, as it is used in copyright, is based in a Western historical and philosophical context and therefore excludes knowledge created in another type of society. The consequences of this exclusion have effects on development. Further it is stated that knowledge according to the global copyright scheme will be reduced to a commodity, which will have consequences not only in societies in the global South.

This thesis deals with urban planning in connection with social and spatial integration.It´s a study of a new planning project in Malmö in southern Sweden. It´s an interesting case because this new, fashionable area will be located next to areas facing socio-economical challanges and stagnation. By using two theoretical models I analyse how the visions for planning a city are formulated and applied when policy is going to be operated. My models are ?the balanced community? and ?the dual community? .The conclusion is that the focus for Malmö and Hyllie is going towards emphasing the creation of attractive but segregated districs in a city.
