Det finns en rad satt att beskriva gallringsformen. Ofta används begreppet gallringskvot i dessa sammanhang utan att närmare ange vilken metod eller definition som använts for att beräkna den. Detta kan lätt leda till att missuppfattningar uppstår. Denna studie belyser olika definitioners känslighet for bland annat beståndsstruktur, gallringsform och stickvägsavstånd. Studien innehåller dessutom en jämforelse mellan olika metoder att mäta och uppskatta gallringskvoten i ett bestånd.

Jag har i mitt examensarbete skapat ett cykelmärke. Syftet har varit att fördjupa mig i grafisk design och skapa en komplett grafisk profil till ett företag och samtidigt att lära mig mer om hur man skapar en varumärkesidentitet. Det konkreta målet var att ta fram tillräckligt mycket material för att cykelmärket, komet, ska kunna lanseras på riktigt. Alltså ett identitetsprogram med grafisk profil, en provcykel, kommunikationsmaterial, en hemsida, en katalog, ett event etc..

Detta examensarbete har utförts i samarbete med ett företag som önskar vara anonymt i rapporten. Företaget har nyligen fått höjda produktionsmål då de fått ta över produktion från en fabrik som håller på att avvecklas. Då arbetskraften fortfarande är densamma har detta lett till att de anställda får jobba övertid. Studien har huvudsakligen fokuserats på en avdelning inom företaget men till viss del har studien också krävt att mindre delar av de två andra avdelningarna också studerades.Syftet med projektet var att se över hur arbetsprocessen kunde effektiviseras så att målen kan nås utan att personalen behöver jobba övertid. Som ramverk för projektet användes en version av Six Sigmas lösningsmetodik DMAIC, nämligen RDMAIC, där en Recognize-fas har lagts till i starten av arbetet.

AbstractThis work was assigned by a technological company that manufactures gas detectors in which the sensor signal is processed using digital filters. These filters have been developed by a consultancy firm which converted previously used analog filters to digital filters. The purpose of this work has been to analyse inadequate, and sometimes erroneous, documentation from the project in order to provide the company with know-how and tools for further improvement of their products. The work has been done using the simulation software COMSOL which was bought solely for the project. Analysis showed serious flaws as well as pure errors in the consultant?s documentation.

Background: The debate about environment, labor conditions and aid to developing countries has the last years been a much discussed subject The pressure on the companies to live up to their responsibility is beginning to be noticed in the market.Purpose: To find out if a retail company investing in Corporate Social Responsibility thereby direct can effect it?s stock value. Using interviews to investigate if and how stock analysts and corporate finance professionals valuate a company?s CSR initiatives.Theoretical perspective: The description of CSR is leading to the main theory, The Brand Value Change, and the Market Hypothesis. Additionally a theory of the Consumer Buying Process and CAPM-model about financial risks is presented.Method: An event study of 30 companies to investigate if there is any change in their stock values and interviews with three professionals from the financial sector to find out about their attitude to CSR.

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.

When protection zones for wells are delineated, it is important to acquire good knowledge about possible travel time from different points in the catchment area to the well. Often, simple analytical methods are used for estimating travel times and the assumption is made that the hydraulic conductivity is relatively homogenous within the aquifer. Nevertheless, many aquifers are strongly heterogeneous which may lead to differences between estimates and actual travel times. As a part of the process to develop improved methods for delineating protection zones for groundwater supply wells, a tracer experiment was performed in a glaciofluvial esker formation in Järlåsa. On the basis of the experiment, a numerical flow model was created for the test site.The purpose of this master?s thesis was to apply the flow model to an aquifer where the hydraulic conductivity shows great variability and should be described by a stochastic distribution.

Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

Affärsresandet och mässor har funnits i alla tider, den första världsutställningen genomfördes redan år 1851. MICE-industrin (Meetings, incentive, conference och exhibition) utbreder sig allt mer över hela världen. Detta har resulterat i utvecklingen av allt fler anläggningar och diverse resurser. En oro har på senare tid uppkommit gällande om expansionen kommer att skapa en mättnad av marknaden. Vilka resurser krävs egentligen för att en destination ska vara intressant för MICE-evenemang? Denna studie avser att undersöka detta genom kvalitativa intervjuer med verksamma eventföretag inom MICE-industrin för att sedan sätta det empiriska materialet mot tidigare framforskad information kring detta.

The purpose of this randomized controlled study was to investigate the effect of internet- administered guided self-help for women suffering from psychological problems following traumatic childbirth. The eight-week treatment program consisted of written chapters based on cognitive behavioral therapy. 56 participants were randomly assigned to a treatment group (n = 28) or a waiting list group (n = 28).The results showed that post-traumatic symptoms decreased as a result of the treatment, with large within-group effects measured by both the Traumatic Event Scale (TES) (d = 1.33) and the Impact of Event Scale-Revised (IES-R) (d = 1.3). The difference between the groups was only significant when measured by the IES-R in which case the between-group effect was large (d = 0.97). The proportion of the participants who showed clinically significant improvement was considerably greater in the treatment group than in the waiting list group.

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

Purpose: To examine how video-game releases affect the share price, and if video-game reviews have any impact on the share price of gaming corporations. Method: A quantitative deductive research approach is applied with event study methodology used as basis.

A total of 29 video-game launches and 85 reviews where examined.  Theory: The study is based on The Efficient Market Hypothesis, Agent Theory, Public Relations Theory, Nextopia and previous research.Results: The result contains 114 observations in five companies.

The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.

Ordet upplevelse används idag av många företag i olika branscher för att fylla sina tjänster med värde. Inom marknadskommunikation har byråerna börjat använda sig av upplevelsemarknadsföring för att tränga igenom mediebruset och tillgodose kunder och konsumenter. Syftet med uppsatsen är att undersöka hur kommunikationsbyråer, som profilerar sig inom upplevelsebaserad marknadsföring, använder begreppet upplevelse och därigenom uppnå förståelse för vilken generations upplevelseproduktion de arbetar med. Jag utgår ifrån Bosjwijk, Peelen och Thijssen (2007), vars modell innebär att det finns tre generationer upplevelseproduktion, varav den första generationen, iscensättning, innebär att organisationen utformar upplevelsen för individen. I den andra generationen, samproduktion, utformar organisationen och individen upplevelsen tillsammans.
