Flygbildsanalys av trädskiktets status efter brand : en metodstudie

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.

Carbon offset management : worth considering when investing for reforestation CDM

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

Autenticitet i ett öppna data-sammanhang : Utmaningar och möjligheter ur ett arkivvetenskapligt perspektiv

By tradition, archival sciences has emerged in a context with defined information processes, with explicit information producers and custodians to which consumers make requests for the information. In this process, the archival science has developed methods and strategies to preserve authentic and reliable records and by that providing trustworthy information. In an online society, people are using the internet to get information for different purposes. Even though there is no legal obligation to guarantee the authenticity, it is of societal importance that the end users get trustworthy information. In this online context, open data is a trend that is growing fast over the world and it is interesting because its conditions raises many questions regarding authenticity.Since open data is free to reuse, link and combine with other information, and it is preferably in primary format it raises questions about how to maintain the integrity and identity of the information, which is the constituents of authenticity as it is used in this work.

Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

En studie i hur järnvägens möjligheter kan appliceras inom AB Volvo : med hänsyn tagen till företagets logistikkrav

In the year of 2011, the new CEO of AB Volvo announced a major reorganization. This reorganization was a contributing factor to the start-up of this thesis.Volvo Group Logistics Services (VGLS) is Volvo Group?s global logistics partner, which designs, manages and optimizes all of the group's incoming and outgoing logistics flows. With the reorganization, VGLS started a project regarding responsibilities around railway flows. Within the project a demand to collect logistics requirements occurred.

Tillväxt i medelstora företag: En problem- och åtgärdsanalys för tillväxt hos Sveriges "bortglömda" företag

Many sources point to the same conclusion; throughout the history the research sphere, mass media, governmental industry policies and public life in common have not paid the same attention to medium-sized companies as to small, new or large companies in Sweden. Yet, there are some researchers claiming the need for the medium-sized companies to grow, becoming tomorrow?s Swedish new large companies. Hence, the need for understanding the specific growth conditions of the medium-sized companies are definitely clear. This study aims firstly to identify whether there are specific requirements and obstacles for growth in connection to being a medium-sized company.

Modellering av reflektans från ett sockerbetsbestånd med hjälp av en strålningsmodell

The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has beenused to simulate the reflectance of a sugarbeet canopy. The simulated reflectancevalues show high absorptance in the VIS area, compared to field measurements, andhigh reflectance values in the NIR area. The errors may be due to overestimation ofclorophyll content in the sugarbeet leaves and scattered light during fieldmeasurements. The estimation of the clorophyll content where carried out using thePROSPECT-model by Jacquemoud & Baret (1990).During the vegetation period, the state of the canopy moves towards a closed canopy,with sparse vegetation in spring. The MCRM-model was used to perform a ?spring?simulation, which was compared to the original simulation.

En kostnadsanalys av energieffektiva flerbostadshus

In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.

Tillämpning av GIS-analyser i MKB

The reason for performing an Environmental Impact Assessment (EIA) is to incorporate environmental concern in different kinds of plans and projects. The purpose of such an assessment is to identify and describe direct, indirect and cumulative environmental impacts.Geographical Information System (GIS) is a tool that can be used to combine spatial extension of both sensitive areas and different environmental impacts in a quick and easy way. Because of that, descriptions of environmental impacts and motivation of different standpoints on a specific issue can be more correct and easier to make if GIS is used as a tool.Hence, GIS can contribute to improve the quality of Environmental Impact Assessments. If the benefits of using GIS are to out weight the costs, geographical information of satisfactory detail, actuality and accuracy need to be available at reasonable prices.In this paper, case studies are carried out for three different geographical analyses to investigate the use of GIS as a tool in EIA. From these case studies, more general conclusions about the benefits and limitations of using GIS for Environmental Impact Assessments are also drawn.

Uppdatering av metadata i ett Data Warehouse: ett organisatoriskt perspektiv

Data Warehouse är ett relativt nytt fenomen i jämförelse med traditionella databassystem, och i och med de senaste årens kraftiga tekniska utveckling har förutsättningar för att realisera konceptet skapats. Inom branschen finns ett antal problem rörande metadata, som i denna uppsats legat till grund för vår inriktning. Många av dessa problem beskrivs utifrån ett tekniskt perspektiv, vilket detta arbete inte gör. Vi har istället valt att undersöka vilka problem som föreligger vid säkerställning av att metadata hålls uppdaterat i ett Data Warehouse med hjälp av tydlig ansvarsfördelning. Vi har funnit att det föreligger vissa likheter mellan de problem som konceptet Knowledge Management angriper och de problem som en organisation ställs inför när man söker säkerställa att metadata hålls uppdaterat med hjälp av tydlig ansvarsfördelning.

Objektiv rörelseanalys : ett stöd vid den visuella bedömningen av hälta hos hund?

Lame dogs are a common group of patients for the practicing veterinarian. In the literature it is described how a clinical examination can be performed, based on general clinical-, orthopedic- and neurological examination, and visual evaluation of the dog when standing and during motion. For research, objective gait analysis systems are also used to study clinically healthy and lame dogs during motion. The aim of this degree project was to compare objective kinematic gait analysis with a visual evaluation of dogs with different types of lameness. The project was a pilot study to show if objective gait analysis could be used as a support for the visual examination. Ten lame dogs of different breeds and with different diagnoses were included in the study. They were all patients at the University Animal hospital, Uppsala.

CSR i plast- och kemibranschen

Corporate Social Responsibility (CSR) is a topic that is becoming increasingly important in today's society. CSR is a concept whereby companies voluntarily integrate social and environmental concerns both in their business but also in interaction with their stakeholders. The society of today sets high expectations for how companies take their social responsibilities, especially in industries where the risks to individuals and the environment are high. In this study, we tried to answer the following questions; what kind of responsibility do companies in the plastics and chemicals industry claim to take and why might this be due? What differences exist between the investigated companies in the industry and what may these differences be rooted in? The purpose of this study was to obtain an understanding of the interest in working on sustainability in the plastics and chemicals industry.
