Fragmentation and reduction of forest area is a threat for many forest species and their habitat. Deficiencies in forest quality, such as lack of dead wood and old trees, are one explanation of the threat. The most important action to prevent the continued loss of forest types is to protect forest, but also to restore and to create areas that not previously had high nature values. Hence one of the key strategic roles for Fritid- och Naturkontoret, Uppsala municipality, is to monitor biodiversity in the context of urban planning. The majority of the Uppsala municipality residents live in urban areas and most of them spend some of their spare time in natural areas in cities and their immediate surroundings. Exploitation in and around Uppsala is high, but it is important that there is enough nature close to houses to meet the residents? needs of recreation.

What causes people to move within and between certain places and not within and between others? How do physical outdoor environments affect the way people act and move? Do different environments generate different body language and mimics in the bodies that inhabit them? In my pursuit for answers to these questions I studied literature and initiated and took part in dialogues in the form of workshops, all of which has resulted into this thesis. My questions have initially arisen from reflections of my own environment and how it not only affects my mental condition, but also my actions. Drawing upon the hermeneutic term ?preconception? I trust that what we label ?truth? is constructed by our lived experience and the society we grow up in.

The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.

This Masters thesis is made as the first of two visitor surveys of three urban forest areas. These areas are; Skutan recreational area in Haninge, Ugglevikskällan on Norra Djurgården in Stockholm and the Paradiset Reserve in Huddinge. The study is made in cooperation with the managers of the three areas operating within the European Union Life Project regarding Urban Woods for People. The goal has been to collect data through studies of visitors and close by residents in the three areas. The results are to be used as primary values for the follow-up as well as a basis for managerial decisions. The interviews and surveys are also constructed in a fashion so that they can be used for the follow-up study. For the Skutan recreational area the mode of contact was by sending forms to the nearby residential areas.

Detta arbete är ett examensarbete om markpackning i urban miljö med fokus på att undvika, åtgärda och ett växtval. Arbetet är skrivet på 15 hp inom LTJ-Fakulteten under perioden 2009/2010. Arbetet har olika avsnitt som tar olika ämnen inom markpackning.Den första delen handlar om bakgrunden till arbetet där det tas upp att ämnet kommer i grund och botten från Alnarp förskola samt att det är ett stort problem i den gröna sektorn. Själva syftet med arbetet var att få en bättre förståelse för markpackning hur det uppstår, hur det kan undvikas och åtgärdas. Det ska kunna ge grund till kommande arbeten i ämnet eftersom det är en sammanfattning av forsknings- och rapportmateria .

This is a thesis on how to develop and densifythe suburb of Joanneshov south of Stockholm.Based on Stockholm?s urban history,Stockholm master plan in 2010, the currentdensity and sustainability debate, literarystudies, as well as a variety of analysisof the site it all ends up with a proposal onJohanneshov. The goals have been workedout during the work and has resulted inthat we want to extend the inner city streetand linking Johanneshov with surroundingdistricts, but we also want to create a wellused, diverse, urban area where the humanis in focus and a district that is easy to read.Much of the work is devoted to show howStockholm has developed historical and totry to put the future in a context, but also a lotof work has been put in the information andthe analysis of the site chapter. The plan proposalis still considered to be the work focus.Johanneshov is surrounded by Årsta inthe west, Hammarbyhöjden in the east,Enskede in the south and Södermalm inthe north. Gullmarsplan is a typical 40thcentury area with a functionalist structure.Johanneshov is with Gullmarsplan,the Globe an the Slaughterhousearea, an important node for the southernsuburbs as a place for communication,sports, entertainment and shopping.Today Nynäsvägen divides the area intoa western and an eastern part.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

In Dar es Salaam, as in many cities in developing countries, green areas are decreasing due to the fact that the growth of buildings, infrastructure and services has become a priority. As the population increases more buildings and infrastructure are needed and much of the building activity takes the form of uncontrolled settlements, which encroaches the public green space. Dar es Salaam has approximately three million inhabitants, of which about 70 percent are living in informal settlements. The aim with this study is to make a design proposal for a park and recreation area where the Msimbazi river basin in the centre of Dar es Salaam is today. The basin consist of a few playing fields, footpaths and some urban farming, but apart from this it mostly consists of unused grasslands, swamps and forests. Because it is an unsafe place and badly connected to the rest of the city infrastructure, it has become a barrier. The annual flood combined with the constant still shallow water creates a good breading ground for malaria mosquitoes.

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

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.

Det här kandidatarbetet behandlar hur en typisk förortsmiljö, Rotebro centrum i Sollentuna kommun, med hjälp av rådande blandstadsidéer kan utvecklas till att bli en miljö som präglas av blandade och integrerade funktioner. Med utgångspunkt i kommunens översiktsplan tas ett gestaltningsförslag fram med hjälp av rådande teori. Syftet med uppsatsen är att undersöka och beskriva blandstad som ett planeringsbegrepp och se hur Rotebro centrum kan förtätas och utvecklas med en blandstadskaraktär för att upplevas trivsamt, tryggt och levande. Hur skapas en tydligare urban karaktär och vilka funktioner kan inkluderas. Genom aktivitetsobservationer, intervjuer och platsanalyser identifieras nuvarande problem och möjligheter. Nuvarande svårigheter finns i bullerproblematiken som idag gör sig påmind i stora delar av området, från både passerande tågtrafik, närliggande motorväg och flygtrafik.

När tekniken ?cloud computing? eller datormoln först upptäcktes var det en teknik som krävde att en användare införskaffade hårdvara och kunskap för att skapa denna miljö. Denna teknik kunde inte uppfylla sin potential pågrund av en otillräcklig internetanslutning. I dagens moderna samhälle är tillgång till fiberanslutning stor och kostnaden låg vilket har lett till att antal hushåll med fiber fortsätter öka. Detta har medfört att datormoln i nutid kan vara av intresse för en hemanvändare, detta i form av molnlagring.Det här examensarbetet undersöker prestanda, säkerhet, integritet, replikering och skalbarhet hos två olika molntjänster.

Denna uppsats behandlar en algoritm som löser linjära optimeringsproblem. Algoritmen bygger på en liknande idé som simplexalgoritmen men i denna kan startvärdet även vara en punkt inom tillåtet område eller på randen till detta område. Det behöver inte nödvändigtvis vara en hörnpunkt, vilket simplexalgoritmen kräver. Under algoritmens gång kommer iterationsvärdena att ligga på randen till det tillåtna området för att slutligen hamna i ett hörn. Därefter går iterationsvärdena från hörn till hörn tills slutligen optimum har nåtts.

Odefinierade platser värderas ofta negativt och förnippas frekvent med social problematik och oattraktiv utformning. Det finns dock en alternativ inställning till dessa platser. Till skillnad från många offentliga ytor som kan inrymma exkluderande och kontrollerande designelement finns odefinierade platser där olika sociala grupper kan mötas utan mallar och begränsningar. Syftet med denna uppsats är att undersöka odefinierade platsers eventuella sociala värde ur ett kommunalt stadsplaneringsperspektiv i Sverige och jämföra det med den alternativa inställning som presenteras i litteraturen samt med de eventuella värden som observerades vid platsstudier i Uppsala. Det kommunala stadplaneringsperspektivet erhölls genom en enkätundersökning som skickades ut till trettio kommuner i Sverige varav sju svarade.
