Hydropower is an important source of energy in Sweden and accounts for about 46 % of the total energy production. Sweden has about 1 200 hydropower plants and with the intention of raising the pressure head of the water and to store water, dams are built by the power plants. The storage reservoirs make it possible to adjust the energy production by demand and season. Dams in connection to the reservoirs are subjected to additional loading during periods of high floods or when an icecap in the winter is formed on the reservoirs. In order to maintain the dam safety, the power companies in Sweden are working with guidelines for dam safety from RIDAS.

We live in a high tech era of electronic media, which is changing our lives (Giddens, 1999). Apps are examples of technologies that affect our lives. An interesting question in this context is what apps will have for significance; on one hand for the development of technology, and on other hand for humans? relation to technology. Since the development and change process are central issues in the science of education I will explore the development of applications.

SammanfattningOCS950(Object Controller System 950) är en av Bombardiers produkter som hanterar säkerhetssystemet i järnvägstrafiken. Det består av olika delsystem och strömförsörjs mha nätaggregat (PSU ? Power Supply Unit). I den här rapporten undersöks den befintliga PSU74-modellen samt nya switchade nätaggregat som finns på marknaden.Bakgrunden till att Bombardier vill byta ut PSU74 mot ett nytt switchat aggregat är att PSU74 har en vikt på 14 kg och tar stor plats i el-skåp. Ett swichat nätaggregat väger ungefär 1,5 kg och är så pass kompakt att det tar litet utrymme i el-skåpet.Bombardier har medvetet väntat med att gå över till SMPS eftersom tillförlitlighet blir ett problem.

Fish-head pendants are one of the characteristic Gotlandic Late Iron Age artefacts. This object has been rather neglected and mainly considered as an insignificant embellishment, normally worn as a neck-collar and seen as an artefact include in the typical Gotlandic set of female jewellery.The fact that the fish-head pendant has a very long life span, which stretches from grave-finds in the Early Vendel Age to hoards in Viking Age as well as secondary usage as brooches in the Early Middle Ages, makes the artefact an excellent starting point for discussions on social practices and change through material culture. It's shown in this study that, contrary to previous beliefs, the normal usages for fish-head pendants is as solitary pendants and not as neck-collars. Neck-collars is shown to have an intricate relation to inhumations for young individuals, whereas solitary pendants are found in cremation deposits for adult individuals, something that relates to a fixed social practice mainly in the period 700-900 AD and that develops from the cremation funeral practice. This particular social practice relates to aspects of attraction and protection and continues in to the 10th century outside of funeral structures, which is shown by the composition of hoard-finds from the 10th century, but is totally absent when the pendants is given a secondary usage as brooches in the end of the 11th and beginning of the 12th century.

SammanfattningSyfte och frågeställningarPeabody Developmental Motor Scale 2 (PDMS-2) är ett motoriskt test för barn upp till sex års ålder. Syftet med denna studie var att undersöka genomförbarheten hos Catch And Run On LINE (On Line), ett nytt grovmotoriskt test för förskolebarn, samt att utvärdera överensstämmelsen (concurrent validity) mellan On Line och den grovmotoriska delen av PDMS-2. Frågeställningarna som ställdes var hur den totala poängen överensstämmer mellan On Line och PDMS-2 och hur lång tid det tog att sammanställa resultatet av de två olika grovmotoriska bedömningarna.MetodOn Line utformades som en kortare variant av PDMS-2. Alla barn (n=26) som remitterades till sjukgymnastiken på Sachsska barn- och ungdomssjukhuset för en grovmotorisk bedömning och som besökte författaren där under 4 månader erbjöds delta i studien om de hade börjat gå, men inte hade fyllt 6 år. Barnet bedömdes vid ett tillfälle.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

Staden Sulaymaniyah ligger i den kurdiska delen av Irak och har på senare år utvecklats då många valt att flytta från landsbygden till den centrala delen av staden. Nybyggandet sker under tidspress och långsiktigt hållbara lösningar prioriteras inte. Målet är att ta fram ett hus som är anpassat för majoriteten av befolkningen och samtidigt få ett bra och energieffektivt inomhusklimat. En faktainsamling genomfördes för att ge bakgrundsinformation till projektet. Vidare gjordes en planlösning till huset i AutoCAD vilken har använts som grund till utformningen av huset och smarta lösningar.

The companies of today compete about the consumers? attention. In a society where the speed is increasing and the trends are constantly changing the marketing of today will soon be obsolete. This is something that is clearer in the fashion business where the consumers always are looking for news at lower costs. It?s no longer an economical question to be able to wear the latest fashion trends, the availability of cheap fashion clothes is constantly increasing.

The thesis work focuses on marketing and its point of departure centers on mapping the utilization of social media as a form of marketing. The choice of this thesis subject has been deemed by the authors as one of particular interest due to the current popularity of social media in the Internet connected society and their use as marketing tools. Specifically, this thesis sets out to explore how companies exploit social media tools in marketing and how their use affects retail operations and customer relations in an effective and creative way.The report concentrates on qualitative data collection, the interview answers of four respondents, of which, two are considered experts within the field of social media. The choice of suitable respondents was strategic with the goal of covering as large a portion of the social media field as possible; one social media educator that works with companies and one who assists companies with social media applications. The remaining two respondents work in marketing and communications and employ, as part of their job, social media tools such as Facebook and Twitter.

The foremost objective of business organizations is to generate value for shareholders and to opt for strategies which optimize it. Hence it is of key concern for business leaders to appreciate how operations best are run to maximize value creation. This study explores how financial theory can reveal the link between one particular business strategy and the corresponding effect on shareholder wealth. The question in focus is whether construction companies can enhance their value creation by implementing shift-work to increase the weekly production rate. The thesis particularly targets apartment block projects in Sweden and has the construction company Peab AB as primary object of study.

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

AbstractDrinking water is an important resource on Earth both for humans and animals. Although most of the surface is covered by water only a small quantity is available as drinking water. Our manner of living creates a lot of pollution which has an environmental impact. Groundwater has a protracted turnover time in the soil and it can take many years before the effects of human impact are detected. The Swedish environmental object is ?Good groundwater quality? which aims to provide a safe and sustainable supply of drinking water today and in the future.

Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It?s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it?s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website.

We live in a world where the resources are not equally divided and that is why charity work is needed. The United Nations Children?s Fund, UNICEF, is a global organization that works for children?s human rights around the world. But perhaps even charity work, which´s often glorified in the society, need to be looked at from different directions. Research about intercultural education, globalization and charity shows that even good deeds can end up reproducing the problem that was supposed to be solved in the first place.

I gained my interest for color during my years at the landscape architect program. I felt that you as a student in design courses constantly were faced with the problems of coloration. A subject that I perceived to be difficult, especially for us students that lacked the experiences from how a project on the drawing board turns out when it finally is built. As a professional landscape architect you there have a greater experience but I wondered how much awareness about color you actually have as a professional. How does one think about coloration and how can you use color as a formative tool? And how does color truly affect us humans? Does color have significance for the experience of landscape architecture? The object with this project is to illustrate color and it?s place in landscape architecture.
