Analys och gestaltning av miljön kring vattentornet i Uppsalas stadsskog
The water tower in Uppsala city forest was built in the late 1950's in what is now a nature reserve. The unique place was supposed to be visited by people, which is currently not the situation. This bachelor thesis aimed to perform an analysis and make a design proposal for the environment surrounding the water tower. The analysis was performed using the methodology previously described by architect Arne Branzell. The methodology focuses on how a space is perceived by a person moving through it.
Identifiering och reducering av köer i samband med återbesök
Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL? How does the decision of sending product LCL or FCL influence the delivery service? How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL? Method ? A total cost model was developed. This model is supported from existing literature.
Politiskt utanförskap : en studie av invandrarsammansättning, kommunorganisation och kommunpolitikers demokratisyn som förklaringsfaktorer av underrepresentation av invandrare.
The development that the Swedish society has experienced during the last four decades and the higher part of the population coming from foreign countries calls for a more intensive research on the situation of these groups. The purpose of this study is to find explanations of the differences in the share of immigrant politicians in Linköping and Norrköping. The starting point of the study is a model of factors assumed to affect the representation of immigrants in the municipality assemblies. The immigrant composition, the municipality organization and the view of democracy of the politicians, are all assumed to affect the civic participation. The civic participation is then assumed to affect the representation of immigrants in the municipality.
Prognostisering av räntabilitet på eget kapital - Förbättras möjligheten att prognostisera räntabilitet på eget kapital om hänsyn tas till earnings management
Prior studies have shown that earnings management can be used either to inform or to mislead investors about the future performance of a company. However, few studies have examined the impact of earnings management on forecasting return on equity (ROE). The aim of this thesis is to investigate whether the ability to forecast next year's ROE is improved when taking earnings management, measured as discretionary accruals, into account. This is examined by comparing a forecast model that takes the magnitude of discretionary accruals into consideration with a model that does not. The study is based on companies that were listed on the Stockholm Stock Exchange during 2002-2012.
Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara
The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
Sjöars känslighet för klimatförändringar ? vilka faktorer påverkar?
The Earths climate is changing at a higher rate, i.e between 1861 and 1994 the annual mean temperature in Scandinavia increased with 0,68º C and according to recent climate models the annual mean temperature is likely to rise with another 3º C during this century.A warmer climate in many ways is associated with changing conditions for lake ecosystems. An expected higher water temperature and a stronger summer stratification of the water column increases the risk of anoxic conditions at the lake bottom. Thus anoxic conditions are likely to cause a phosphate leakage from the sediment, i.e. a higher internal loading of phosphate.In this project, the extremely warm summer of 2002 has been used as an example for a possible scenario for a future climate. By comparing levels of phosphorus in the summer of 2002 with a ten-year median value, a phosphorus related sensitivity to climate change has been analyzed for 55 Swedish lakes.
Miljösystemanalys av alternativa avloppssystem i ett urbant område ?Svartvattensystem : Skogaberg ? Ett pilotprojekt i Göteborg
Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.
Wheat : an analysis of variables determining the Swedish price of wheat
Increasing volatility and less political intervention from the CAP in the market price of wheat is making it more difficult than in the past for Swedish farmers to determine the price at which they should sell their wheat. In the past, the Swedish farmer-owned company Lantmännen has traditionally set a guideline price for Swedish wheat every year to which farmers could adapt, but ceased doing so last year. Therefore this study sought to identify the parameters on which the price of wheat is dependent on by using a reduced form model. The perspective adopted was that of farmers. The model proved able to identify the main factors determining the annual price fluctuations in wheat, with all variables included having an impact on the wheat price, except export quantity in the previous year.
I tid och rum : en upplevelseanalys av Kärnan
In 2005 Gunhild Eriksdotter published Behind The Facades in which she analyses the ways of approaching historical buildings in archaeology. Eriksdotter emphasizes that the archaeology of buildings is in dire need of renewal videlicet the traditional outlook on buildings as two-dimensional objects need to change. She develops a method of analysing the spatial dimensions in a three-dimensional world. By fusing theories and methods in excavating archaeology and architecture, she is able to give us a new way of approaching buildings. Her method includes the analysing of a buildings material, spatiality and use.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.
Vindpark Vänern : Fundamentteknik och Logistik
An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.
Kostnadsallokering genom ABC-kalkylering ? en empirisk studie av OMX
As IT service departments in organisations are becoming more complex and customised, the indirect costs are increasing in relation to the total costs. The difficulty of fully estimating and identifying the spread of the cost in the IT service department is increasing. As a result, firms tend to budget the business unit as a total cost rather than as a spread of defined costs. In order to deal with this challenge an ABC calculation will be applied. The Time Driven ABC model will be conducted in OMX´s Servicedesk unit within the IT services.

NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
Utveckling av beslutsstöd för kreditvärdighet
The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.
