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.

Tjäna pengar som gräs? :

The producers of grain in Sweden are facing a rough future. The competition is getting harder all the time, in Sweden, in EU and also from the ?world market?. The producers have to be more efficient and have to have bigger units. Many producers might have to look for new alternative production opportunities.

Elev i behov av särskilt stöd : Vad betyder det?

This is a qualitative study of how 4 school teachers and 3 special educational teachers define the term ?pupil in need of special education?. They have each one been interviewed about this term, by the means of a semi-structured interview. Afterwards the collected information has been analyzed and seven major themes have been arranged out of them. From these themes it is possible to see that the term is hard to define, since the participants all believe that it should be decided by each individual case, if the pupil is in need of special education or not, and that the education in itself has to be relevant to the need, which means one cannot decide what special educational needs are, without a student who is in need of them.

Med andra bilder inga ord. En illustrerad berättelse.

This project has been about illustration, text and format with illustration as the main communication path.A study has been made of how these three elements interact, particularly how text and format affect the illustrations. The goal has been to create an illustrated story in a form of a book. The story is about the feeling of being alienated from other people and invites the reader to make their own interpretations. The main target audience has been the ones who is interested in illustration and storytelling, no matter of age.Colors has been inspired from animated movies and the natur. Various textures such as wood, fabric and metal for example has been scanned to create a rough feeling.

Stereoskopisk 3D-film : En studie om tittarens upplevelse av 3D-film

Since the release of Avatar in 2009, the 3D movie industry has experienced an apparent growth. Almost all blockbuster movies are being released in 3D at the cinema, but the 3D format has been met with mixed opinions by the consumers. Some argue that 3D is the future, while others believe that the 2D format is enough for an appreciated movie experience. Through a qualitative survey, twenty participants with 3DTV in their homes answered questions regarding their experience of 3D movies and what improvements they desire. We suggest that 3D film creates immersion, realism and effects that 2D films can´t handle.

Att se in i framtiden : En studie om hur konceptet insiktsförsäljning påverkar ett B2B-företags försäljningsprocess

Background: The result of our interactive information society is that sales business has shifted from a tactical to a strategical focus, thus companies have had to adapt to this change. The evolution of sales shows that companies have gone from one static model to another, which is discarded by the new concept ?insight selling? claiming that it through insights is possible to be forceful in the, these days, rough sales climate.Purpose: The purpose of the report is to form an understanding of how insight sales affect a sales process.Research question: How does insight selling affect the B2B sales process?Methodology: Process mapping through interviews in combination with organizational documents.Findings: Insight selling affects the sales process by a clearer research mindset and a change in communication in relation to the customer..

Underröjningsgradens påverkan på förstagallringsnetto med flerträdsaggregat

I Sverige finns ca 1,2 miljoner hektar skog som bedöms ha omedelbart röjningsbehov. Skog där röjningen uteblir eller är svag kan komma att klassas som konfliktbestånd. I konfliktbestånd är stammarna många och diameterspridningen stor och dessa kan då behövas underröjas innan gallring. I denna studie jämfördes produktionen, kostnaderna och intäkterna från fyra olika underröjningsbehandlingar, oröjd, siktröjt, röjt allt upp till 5 cm i brösthöjd och röjt allt upp till 7 cm i brösthöjd. Behandlingen oröjd gav det bästa nettot och sämst hade upp till 5 cm efter gallring och uttransport av virke.

Automatisk genreklassifikation : en experimentell studie

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

DET HÄR ÄR OCKSÅ GRAFISK DESIGN - Ett bidrag till diskussionen om ornamentik, funktionalism och kvinnors marginalisering.

This thesis examines the relationship between the marginalization of ornamentation during functionalist modernism and the effect it had on female graphic design practice. By examining the historiography from a gender and feminist theory of history I present a different way of interpreting, not only the history of graphic design but also the concept of graphic design. This thesis does not reach a conclusive result, instead it sets the foundation for further research and illustrates the opportunities that we as graphic designers have to benefit contemporary graphic design by critically reviewing and redefining our history through a diverse historiography..

Relationer och projekt : En studie av det mellanmänskliga i det rationella

Projects are often spoken of in the terms of rational systems. However, some researchers point out the relevance of viewing projects as sets of relationships. Little is published about what aspects of relationships that are important for the managing of projects. We have argued for the necessity of such research. With previous research, our case study and interviews we indentified communication, responsibility, cooperation, togetherness and trust as important relational aspects in projects.The overall perceived success for projects in this case, was increased with the adoption of new agile methods.

Eurokoder : en jämförelse mot BKR

In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.

Genom kunskaper om historien förstår vi nuet : En kvalitativ studie om gymnasieelevers uppfattningar av historieämnet

The purpose of this survey is to better understand how students in Swedish upper secondary school perceive knowledge in history. 44 students from two different schools took part in the survey. The students partaking were asked to make a rough plan for a course in history, in which they were to both suggest contents of the course and also motivate their choice of content by arguing their view of the purpose of knowledge in history. The results of the survey were then compared to the curriculum of the history subject. The survey shows that a majority of the students asked find modern history, especially World War 1 & 2, and Swedish history to be of importance.

Filmkatalogisering: en behovs- och regelanalys

The aim of this thesis is to examine the characteristics of film cataloguing, and to compare general as in library use and specific as in archival use cataloguing rules. Most rules, both in archives and libraries, use the book as a point of reference. This is somewhat unfortunate on account of the great difference between books and films. The method used is studies of literature and qualitative interviews with three persons whose professional duties include cataloguing of films. The sets of rules which are studied are Katalogiseringsregler för svenska bibliotek KRS and The FIAF Cataloguing Rules for Film Archives.

Ljusspridningsvariationer i finpapperstillverkning

The purpose of this Master's thesis is to find possible explanations of variation in light scattering in a fine paper. Samples were collected from each second tambour during a time period of two weeks from a paper machine at MoDo Paper, Husum. Two data sets, consisting of 20 and 95 observations, were selected for extensive analysises of tensile and structual properties. The data was evaluated with multivariate data techniques using the programs Simca and Extract. The results of PCA- and PLS- analysises pointed out 3 of 52 variables as important for the variations in light scattering.

Utvärdering av larmsystem för lageroptimering under trendvariation

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.
