Hållbarhetsbegreppet har fått allt större betydelse. I bankvärlden, är det inte en fråga om, utan hur ett företag ska arbeta med hållbarhet. För att uppnå hållbarhet är det viktigt att förstå hur en strategi måste genomföras, ständigt utvecklas och kontrolleras, för att resultaten ska följa i enlighetmed de strategiska målen..

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

Dokumentet är ett resultat av studier gjorda under kursen Kandidatarbete I Datavetenskap. Arbetet utforskade, genom fallstudie, två egenskaper av distribuerade informationssystem och relation mellan dessa: säkerhet och prestanda. Målet med fallstudien har varit att belysa nackdelen med användning av Secure Socker Layer (SSL) dvs. dess effekt på hastigheten och fördelen med SSL, dvs. SSL:s roll i informationssäkerhetsarbetet.

Stormwater in urban areas has been treated as a problem for a long time. The large proportion of impermeable surfaces inhibits the water from infiltrating in the ground to the same extent that it does in nature. This causes intensive surface flow during rain, which in turn causes inconveniences such as decreased accessability, floods and increased risk of desease spreading. Drainage through pipes is the traditional and usually functional metod for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation.

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

During the last few decades a new kind of business operation have developed and this hasforced organisations to adapt themselves to a new competitive environment characterized byincreased customer demands as well as a larger amount of competitors. Therefore companieshave had a shift in their strategies from focusing on sales numbers to focusing on thecustomer. To build lasting customer relationships, in order to create customer loyalty, havebecome an important part of the organisational strategy and the collection of consumer datais essential in achieving this loyalty. Customer relationship management systems assistorganisations in managing information about individual customers as well as managing allaspects of customer contact, with the purpose of increasing customer loyalty towards thecompany. The collection of consumer data also enables for companies to design personalizedoffers to individual customers in the form of direct marketing.

Regulations on the exhaust emissions of HD-diesel engines are becoming more and more stringent, and therefore, emission after-treatment systems are commonly used. These systems rely on catalytic conversion of NOx,CO , and HC emissions, and are thus dependant on temperature. At low load of the engine, exhaust temperatures are not sufficient for the after-treatment components. Therefore, means to increase the exhaust temperature while maintaining low emissions and fuel consumption are needed.The focus of this project has been to develop strategies for the lift profiles of exhaust and intake valves in the engine, with the goal to raise exhaust temperature in combination with low emissions and fuel consumption. The strategies have been tested in a single-cylinder research engine equipped with a hydraulic variable valve actuation system.

This study is a thorough comparison between what people think about the website www.sl.se, which is a Swedish web-based travel planner for Stockholm metropolitan public transport (such as subways, busses and suburban trains), and how these views compares to the design of the actual website itself. The travel planner offers a wide range of functions and services for their targeted audience to find the fastest route between their current location and their destination. These functions are for example real time information on hold ups and malfunctions on different travel routes, and an interactive map of specific destinations so that the user can get a clear view of the area and nearby traffic stops. But how much does the average user care for these functions, and how often are they used on an average visit? What are the users? motivations when they visit the site? Earlier research suggested that there are services and functions on this website that are useful and well crafted, but that some people may not be aware of.

Systems development methods has always been an important part of the systems development process. It affects not only the product, but also the organization itself. Today more and more companies are abandoning the more rigid traditional methods for the more flexible agile ones. A transition like this is bound to affect the product and the organization, but in what ways? Is it a difficult transition to make, and how does it affect social environment and dynamics? Does it change how people communicate information to each other? This study was conducted at a local branch of a larger international IT-company.

Insufficient intake of vegetables is a reason for micronutrient deficiencies and malnutrition in developing countries. With urbanization, globalization and a growing world population it is of major importance to secure sufficient food supply for the world?s population. Part of the solution to increased food security among the world?s poor could be the introduction of vegetable home gardens, plots for small scale vegetable production which can provide households with sufficient vegetables as well as serve as an extra income source. The study Improving peri-urban home gardens aims at examining the existence of vegetable home gardens in the peri-urban areas of Hyderabad, India.

In today?s society we depend on technology to perform the simplest tasks. Whether we are engaging in conversation with a friend or are navigating in traffic, we are likely to be found with some technological device in our hands. This dependence has grown over a period of time, and many of us have failed to reflect on the impact technology has had on our lives. The emergence of so-called One-to-One projects, where teachers and students gain access to a personal laptop, does however provide an excellent opportunity to do so.

Deep litter is a system for animals kept in separate stalls, loafing and bedding in wind shelters. The litter can consist of different bedding, like straw and peat. The system is allowed to build over and to ensure optimal proportions it is necessary to add new straw regularly and to have good conditions. Important conditions are aerobic state, humidity, amount of organic substance and acceptable temperatures in the litter. The micro organisms are depending on temperature for their living conditions and to get the bottom layer in the litter to start burning.

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.
