Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0

After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.

Simulering av filtrerade skärmfärger

This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.

Modellering av rotationssystem

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

Redovisningskonservatism -En studie om redovisningens försiktighet i Sverige

This study aims to measure the effect of accounting conservatism and to identify thebusiness activities causing firms to undervalue owners? equity. To estimateaccounting conservatism, we have followed the hypothesis that no firm over time cangenerate a return greater than its cost of equity, i.e. CAPM. Thus, if a firm in factgenerates an excess return over time, we assume that the excess return is an estimateof accounting conservatism within that firm.The hypothesis originates from the corporate valuation model ?Economic ValueAdded®? which tries to adjust for accounting bias.

Röstpremien - premien för aktiens rösträtt

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

Produktivitet och kvalitet vid stickvägs- respektive beståndsgående förstagallring :

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

Illustrerad samtid : En studie av hur tre filmer skildrar 1960-talets Sverige med särskilt avseende på konsumtion och välfärd

This paper studies how the ?Swedish model? has influenced the Swedish community during the first half of the twentieth century and how living with this model was like in the 1960s. During the ?60s the laws and reforms created by the ruling socialistic party, SAP, dominated the Swedish society. Their goal was to build Per Albin Hansson?s vision of a welfare state.

Statushantering i Virtual Map med ledningssamordning i BIM

For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.

Busshållplatsers kapacitet : Utvärdering av tillämpbarhet av modell från Highway Capacity Manual 2000 med uinderlag från busstrafik i Stockholms innerstad

Stockholm is growing with almost two fully loaded SL-buses a day. One of the consequences that derive from this is the increase of public transport travelers who put the regionally governed public transport up to the test in terms of its capacity. The Transport administration in Stockholm County initiated 2015 a project with the purpose of simplifying the calculation of bus stop capacities. A hypothesis (set up by the Transport administration) based on that a model for calculation of bus stop capacities could be calibrated for Stockholm conditions is being researched in this bachelor?s essay.The study is implemented by self-collected traffic data from bus stops located in the Stockholm city center.

Medskyldig till folkmord? En studie om internationella samfundets inblandning i folkmordet i Rwanda 1994.

The Rwandan genocide 1994 was a well-planned and ethnic based act that killedapproximately 900 000 people. The UN and the colonial powers are getting much attentionand are worldly discussed about the failure of interference before and during the genocide. Inthis study the history of colonial Rwanda will be analyzed and the UN relation will bediscussed. This will be done by examining how the colonial powers have affected Rwandathrough history and how the UN have responded upon the challenges towards Human Rights.Questions about accountability and failure will also be discussed and analyzed. This has beendone by analyzing highly reliable documents and books by NGOs and scholars.

Modern marknadsföring - filmproduktion

I contacted the production company Salmonfox in the hope that they would have any projects that they needed help with. It showed that Salmonfox just started up an old project that they needed to complete. They wanted my help to edit some trailers and one crowdfundingfilm for the short film called, Captain Sweden (Kapten Sverige). Salmonfox are hopefully going to use the different trailers and crowdfundingfilm to promote the short film and get help with the funding to make a feature. The project began with a pilot study in which I made a time plan and a requirements plan, where the different requirements were set.

Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data

A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..

Kommunikationsstrategi för Renbruksplan : är det en fungerande modell för samebyarna vid samråd?

The reindeer planning system (Renbruksplanen, RBP) is a communication and planning tool designed for Sami groups. A key purpose of this is that it will act as a tool in consultation with other market players, including forestry. Sami groups have asked for a model of how this can be used in a flexible manner. With the Swedish Forest Agency as a project manager, a communication model for how to use the RBP has been designed. It consists of a number of points divided into ?before?, ?during? and ?after? the consultation.
