The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

The preschool constitutes a big part of many children's everyday existence. Its contents are therefore of great importance and the environment deserves a well thoughtout design. In this study, surveys in field and literature have resulted in conclusions around how plants can be used in children's play environments, in order to contribute to the experiencerelated values. The aim is to present conclusions to lean on when drawing up designproposals for new playgrounds, especially where the natural conditions are not so favorable. The first question that is responded to is how plants can be used in order to enrich the children's play environments.

This graduate thesis deals with the challenges facing us as we gradually make our urban environments withtheir many public buildings, such as shops, cafés and cinemas, more accessible for disabled people. Theperspective taken is that of the conservationist, who in her or his profession looks to the cultural andhistorical characteristics in buildings and building environments. In order to gain better accessibility, changesin the physical fabric need to be made, with consideration for the cultural and historical characteristics.The introduction presents the subject of considarate accessibility. The second chapter deals with the legalaspects concerning the protection of buildings as well as the accessibility for disabled people. Severalinterviews with different participants are presented here, aiming to tie the legislation to the reality of theconservationist, the disabled, the civil servant working with accessibility issues and the property owner,whose responsibility it is to make the adjustments necessary to improve accessibility.

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

This paper explores the field of virtual reality and how immersion and presences can be increased when it comes to navigation and interaction with Virtual Environments. The availability of VR technology has sparked a trend, especially in game development. Old ways of designing for interactive environments have to be revised. This is done by exploring the massive body of work done on VR, exploring its underlying concepts, using tested design techniques and ways of evaluating interaction for VR. A design suggestion in the form of utilizing a tablet device as the main input device is derived.

This is a paper about the social services waiting rooms. Our aim with the study has been to:?Describe and problematize the physical environment in social services waiting rooms. A wider purpose is to lift the question about the waiting room as a significant part of peoples encounter with the social services.? To be able to achieve this purpose, we have used two questions: What does the physical waiting room environment look like in social services in Stockholms län? How can we understand and problematize the physical environment factors impact on people who visits these environments? We have observed and photographed ten waiting rooms in ten different social services in Stockholms län.

This dissertation examines how creativity can be of benefit for the school. It discusses if there is a need or demand for it and how the present situation is in Swedish schools. Defining creativity accurately is difficult but it is relevant to look at the environments that use creativity. There is a vast amount of literature that uses creativity and it varies to some extent. Creativity originates from meetings and combinations, both within and outside of the individual.

Previous research regarding the European debt crisis has mostly focused on the purely economic aspects of the crisis. However, there is a strong ?Protestant-Catholic? dimension in Europe, where historically Protestant countries are more prosperous than their Catholic and Orthodox counterparts. This has especially been a fact since early 2010, when several countries within the European Union had their credit ratings downgraded. Is this phenomenon merely a coincidence? Or could the roots of the recent troubles in Europe have a basis in historic religions? To tackle this question, Max Webers ?s 110 year old study The Protestant Ethic and the Spirit of Capitalism is brought back into light and used as a tool for analysis of the crisis.The results show that not only are Protestant countries in general more prosperous, but they also have lower corruption and their citizens have a higher level of trust towards the government.

Introduction: The world is changing rapidly and the uncertainty that characterizes today´s society makes companies preparations for the future crucial. Purpose: To examine how CEO:s in small companies look at the future and what kind of preparations they make in order to meet it. Hereby, our ambition is to find out whether there is a difference between companies working in industries characterized by different degrees of stability. Mode of procedure: The purpose of this thesis has been fulfilled by interviews with four CEO:s from industries characterized by different degrees of stability. Result: The companies working in relatively unstable environments tended to be relatively more flexible and have an emergent strategy formation process, whereas companies working in relatively stable environments displayed relatively less flexibility and tended to have a planning strategy formation process..

In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.

This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people. I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala. The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate. .

Nature-like plantations are areas that, by today?s maintenance procedure usually gains low prioritiy and are forgotten. Most nature-like plantations are currently disadvantaged and have in many cases grown up and formed dense,impenetrable and brushwoody green volumes. These green volumes is rarely used, but usually only fills out gap surfaces. With proper care nature-like plantations can become health promoting environments in the increasinglyhardened urban environments.How vegetation systems work and how trees and shrubs interact is dependent on many factors.

Can landscape architecture be seen as an economical asset rather than as a cost? Can well designed outdoor environments affect real estate values? This study investigates the economical value of landscape architecture and its influence on real estate prices. Research results on the relation between landscape architecture and real estate values are here compiled together with a survey made among players on the Swedish real estate market of their attitudes towards the problem. This study shows that the players on the Swedish real estate market often are unaware of the economical effects of landscape architecture pointed out in the compiled research. The study also shows that to use this information in actual projects several steps need to be taken: better knowledge of the problem, more and better compilations of research results, effective channels to spread the compiled information, proper employment and implementation of the knowledge. Extended knowledge of the relation between landscape architecture and real estate values will result in new ways of making money on outdoor environments. This would in turn have consequences for how the real estate business treat outdoor environments and how landscape architects work. The study is divided into four main questions: 1: Is there a relation between good landscape architecture and real estate prices? 2: What is the view of the players on the real estate market in this matter? 3: Is there more knowledge, research and practical models at hand? 4: What future steps can be taken to broaden the knowledge and apply it to real situations?.

This essay is about the hostility towards strangers and foreigners within a Swedish historic context, not only towards foreigners coming from another country, but also directed to people within the Swedish society among the ethnic Swedes themselves. From their accounts of the concept I will discuss why and how this hostility towards strangers has developed and been expressed when they were younger, but also how they perceive the phenomena today as it express itself..
