Transporttidsmodellering vid provpumpning i heterogen jord : spårämnesförsök i en isälvsavlagring
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.
En förändrad livssituation. Hur anhöriga upplever att livet förändras när partnern får en synnedsättning
The purpose of my study is to investigate teacher?s perceptions of their mission in the preschool class, and how they work to promote children?s written language development. What methods and working methods they use to awaken curiosity and motivate children to read and write. I am using the qualitative research method to get answers to my questions. I have made four qualitative interviews with four teachers in preschool classes from different schools.My questions are:What conceptions does teachers have about their mission in a preschool class?What different methods and approaches does teachers use to stimulate and wake children?s curiosity for reading and writing development?The theoretical basis for my study is the socio-cultural perspective, where learning occurs in interaction.
En undersökning om fallolyckor med gångtrafikanter
The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.
Konsonant- och vokalduration i enaresamiska
SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Indexeringskonsistens: En litteraturgenomgång och en undersökning i LIBRIS
The aim of this thesis is to investigate indexing consistency in LIBRIS, a Swedish national union catalogue, where searches can be carried out among almost five million titles. To calculate consistency, indexing terms of translations and indexing terms of documents in their original language have been compared. I have used a total of 100 such pairs in the study. There is a lot of different methods that can be used when consistency is calculated, in this study Hoopers and Rollings methods have been used since they are two of the most commonly methods used and also have the advantage of being fairly simple to use and understand. In the thesis, differences in consistency between indexing terms consisting of names and general indexing terms and differences in consistency between controlled indexing terms and uncontrolled indexing terms are also compared.
Utveckling av karriär inom en organisation : - Att få medarbetare att stanna
Background and problem: The background to this study is the organizations increased difficulty to retain employees in the organization when more and more employees today choose to do their career in several organizations. The problem to keep the employees in the organization leads to several problems where the loss of experience reduces efficiency and increased risks and cost associated with recruitment are some problems that arise. The problem therefore faced for this study is: How can opportunities for career development within an organization created to get employees to stay over time?Purpose and method: The purpose for this study is to describe how organizations can create opportunities for the development of career that gets employees to stay within the same organization and make their career in this organization. The method used for this study is a qualitative approach where data is collected through semi-structured interviews in a case study.Empiricism: The empirical result have shown there are four factors that an organization should overhaul to create an opportunity for the development of a career that gets employees to stay in an organization over time.
Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader
The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
Tidsstudie - grovfoderhantering :
Since feeding fodder crops to dairy cows is a heavy and time-consuming but often
disregarded line of work, this study wishes to view the different possibilities that are
currently available to decrease the time to feed and apply this knowledge on an
existing farm. For this purpose, four farms have been studied due to what feeding
systems that are currently used and how long time the feeding required. The occurring
systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle
via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer
which fills an automatic feeder.
Nationella prov- som stöd eller som tidstjuv? : En kvantitativ studie om lärares uppfattning av nationella prov
In recent years, more of high stakes (National exam- NP) have been introduced in Sweden and now (2015) the government has decided that the NP in social sciences- and natural science in 6th grade is optional in order to reduce teachers' administrative burden. Based on these reforms, to have more tests in more grades and also on the decision to remove the test, the purpose of this study is to examine how teachers perceive the work of the (NP).A quantitative research was done in the form of questionnaires. The study was based on questionnaires regarding the time for working with the NP and of the intention that the NP should be a support for teachers.The result of the study is linked to school development and the constructivist theory of learning. The results show that teachers perceive work with NP takes a lot of time, where as the time for administration seems to take slightly lesser time than the time for assessing the exams. The results also indicate that teachers perceive NP as supportive, mainly in relation to the curriculum.
Investeringsbedömning av energieffektiva småhus i trä
The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

Ytbearbetning av ersättningssten för kulturhistoriska byggnader
The study investigates questions and considerations emerging when stone in historic buildings needs to be replaced. The focus is on the surface treatment of stone in sandstone façades in pre-industrial buildings. That means buildings constructed by traditional methods and craftsmanship without the use of modern technology.The research issue originates from the extensive stonework that is planned for the façades of the Stockholm Palace. The project includes the replacement of large quantities of damaged stone to newly cut stone. This raises the questions about the use of modern and rational methods for surface treatment on the replacement stone.
Dark Side of Wonderland - en kort 2D-animation med syfte att väcka intresse för en online serietidning
My objective for this project was to create a short but thrilling 2D-animation
intended as promotion for an online comic book. The purpose of the project was
to learn more about animation and graphics, to further my artistic skills and
to learn how to work in Adobe After Effects. I also wanted to learn more about
scheduling, project methods and how to handle stress. During the ten weeks of
the project I have created the story, the storyboard, the character design, the
backgrounds and the animation. The voice over was recorded with the help of a
fellow student who also made the music and the sound effects.
