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.

This thesis was conducted at Mälardalen University in Västerås and Härjeåns Nät AB, mainly in Sveg. Härjeåns Nät AB is a network company that delivers electricity in Härjedalen municipality, Ånge Municipality, Ragunda and Bräcke municipality. The maintenance and dismantling of electricity and broadband networks generates a lot of waste. The purpose of this work is to present proposals on the management of the waste. The goal is that all of Härjeåns offices should have equal management for the waste and an overview of how to manage the various wastes.

When the purpose is to create an illustration plan for a new neighbourhood there arelots of things to think about. In this report follows a description of the three differentplan modells SCAFT/TRÅD, garden city and ekological planning. SCAFT is aplanning model that were used in the 1970s. It contains proposals how to make thetraffic enviorment safer. TRÅD replaced SCAFT in 1982 and it contains also adviceshow to make the traffic enviorment safer.

European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.

Abandoned and unused railway structures often possess great potential if they are reclaimed and reused for new purposes. The thesis focuses on the global trend of restoring and revitalizing these areas, converting them into park areas, rail trails and green corridors in the city landscape, while preserving their ecological, social, esthetic and historic values. These rail areas were often abandoned when industries moved out from the cities, either to industrial areas or abroad. The use of railways for transporting industrial goods was also replaced to a large extent my motorized road vehicles in the mid 20th century, leaving the rails under-utilized. Because of their location and intrinsic values, they can be reused for important functions, such as green areas in the city environment, providing space for recreational activities and exercise and social meetings and interactions. I have closely investigated the three park areas High Line in New York, Promenade Plantée in Paris and Schöneberger Südgelände in Berlin, which have all gone through this transformation in recent years. I have summarized my conclusions in three key concepts to consider: design for social values, preserve the architectural history, and leave room for future evolution. The final part of my work is a design program for an abandoned railways area in Stockholm: Eriksdal railway area.

This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

This report analyzes disposable packaging and returnable packaging with the methods life cycle analysis and life cycle costs analysis. These two different packaging are analyzed through the company Clas Ohlson?s packaging-flow. To get a picture of how the flow works, a visit at the company and email contact have been done with Clas Ohlson to get relevant informationToday Clas Ohlson has a big flow of articles to the stores without larger variations in the demand, with the exception of autumn, which is when customers start shopping for Christmas. Clas Ohlson?s articles are placed on a pallet and are wrapped into plastic-film for protection and to make sure that nothing will be stolen.

När det gäller design av augmented reality­markörer och platsbaserat berättande finns det många aspekter att ta hänsyn till för att skapa en djup och engagerande upplevelse för användaren. Det finns olika tekniska och kommunikativa faktorer att ta hänsyn till, bland annat måste markörerna vara igenkännbara som just markörer samtidigt som de måste vara tolkningsbara av bildigenkänningen i augmented reality­enheten. Mitt i denna konflikt ligger en designutmaning i vilket det estetiska uttrycket och berättandet måste passa in.Denna studie har genomförts som en kvalitativ fallstudie där scenarier och prototyper har utvecklats utifrån designmetoder som bland annat brainstormning och idéloggar baserat på teorier om designprinciper för augmented reality och berättande i olika medier. En intervju med en potentiell uppdragsgivare ligger delvis till grund för designarbetet. Det producerade materialet har utvärderats genom användbarhetstester samt observationer och intervjuer med ett antal testpersoner.Under arbetet utvecklades ?Naturens gång? ? en platsbaserad berättelse med tillhörande augmented reality­markörer.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

Bakgrund: Högre grad av automation i lager har blivit en viktig och tilltagande trend. Lager är en viktig komponent i de flesta flöden och essentiellt i strävandet av önskade servicenivåer då de ofta verkar i det avslutande stadiet i flöden där ordern förbereds och levereras till kund. Den ständigt växande konkurrensen på marknaden har dock lett till att lagerverksamheter ständigt måste arbeta med kontinuerlig förbättring. Genom eliminering av icke värdeskapande moment skapas förutsättningar för att uppnå effektivare lager och överlag en högre kvalitet i lagerverksamheten. Kvaliteten som erbjuds samt kvalitetens betydelse för kunden är det som utgör den totala kvalitetsnivån, eventuella avvikelser från denna nivå betraktas som brister.Syfte: Syftet med studien är att genom kartläggning beskriva hur påfyllnads- och plockprocessen på den automatiserade delen av Staples lager utförs.

In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

The aim of this paper is to find an algorithm to establish and maintain a virtual enclosure around a mobile unit. The area may take any form and should be scalable up to and including national borders. The enclosure is managed on the mobile unit. The target system is Android. Smartphones, tablets and more recently, cameras is examples of mobile units. A modern mobile unit is part of a computer network.

The Nord Stream natural gas pipeline has been a controversial project. The debate was primarily escalated by Poland's strong negative reaction to the project in the spring of 2006 over safety and security and then alternated back and forth in Europe until the approval by the nations most concerned in the Baltic region during the autumn of 2009.In the case study an approach is used that primarily maps out the media image of the various viewpoints that deal with the pipeline and how these viewpoints position themselves, primarily through political and environmental dimensions. Simultaneously there?s an attempt to map out the spatial spread of the media image views as to the proximity and distance to the pipeline in Sweden, Poland and Germany. A key question is whether distance or proximity to a large facility can affect people's attitudes.A parallel focus of the study is to explore the role of the Nord Stream natural gas pipeline in the cross-border hinterland region of Szczecin-?winouj?cie.

In central Jönköping, on Munksjöns northern waterside a shopping centre will be built, on the block Atollen. The construction will begin in autumn of 2007 and will be finished according to plan in 2009. Atollens goal is to counteract the competition from external retailers and strengthen the retail trade in the city centre, leading to more attractive and competitive city centre.Atollen will not be a shopping centre in traditional style and design, it will be focused on shopping and experience. The shopping centre shall be a natural venue with a wide and exclusive store mix, concentrated against trend conscious customers. This will be created with the help of a futuristic design and architecture, with light, open and transparent spaces.
