The city?s public environments are meant to be perceived as safe and inviting areas to visit any time of the day. In recent decades the number of vandalism complaints has doubled and graffiti has become so common that it received a separate category in the crime statistics. With this type of impacts in the public environments the experience are precarious and a boring sight. It?s difficult to put a price tag on these types of crimes, the number of unreported cases suspected to be large.

In Sweden whenever trains or maintenance workers want access to the railway system, their requests of usage and movements are being supervised, granted and handled by train dispatchers. The profession holds a key role in making the complex railway system work in terms of efficiency, safety and delivering on-time arrivals. This master thesis, delegated by the Swedish Transport Administration, has been carried out at the Division of Human Computer Interaction at Uppsala University and at the train traffic control center in Gävle. The aim has been to map what information the train dispatchers use in order to make safety-related decisions concerning their working goals. And further to describe and analyze how the train dispatchers, visavi their tools and systems in the work domain, gather necessary information.The result indicates a complex, diverse and spread out setting of different programs, procedures and tools that make satisfactory fulfilment of efficiency, safety and punctuality in relation to the time table hard.

The management of information is a significant competitiveness in companies. Companies stored and save information every day, and it is very common to save de information in different sources. This makes de management of information complex. To mange, monitor and analyze the information, companies can use a system called Business Intelligence. BI system is an analytical system that extracts and converts data into useful information that helps employees to make informed decisions.

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.

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

The purpose of this project was to produce signal relay stations that could receive information via 2.4 GHz radio and relay the information to a designated target station. If a relay station was located outside of signal range for the target station it was supposed to utilize other relay stations to transfer the information to the target station, so called multi-hop.The would-be application of the relay stations was orienteering. When an orienteer punches a checkpoint the signal stations would relay information of who punched the control, when it was punched and the checkpoint that was punched to the speaker tower in the goal area.The work resulted in prototypes which fulfilled the statement of purpose and was tested at an orienteering competition with satisfactory results. The performance of the prototypes was tested and found adequate for the would-be application..

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.

Over the last few years, many non-governmental organizations (NGOs) in the aid sector have grown and become important economic, social and political actors in Sweden. However this sector has also been hard criticized in terms of aid effectiveness. Church of Sweden (CoS), a well established organization in this sector, has faced new challenges in form of demands from their environment regarding reporting aid work. These demands have pushed the International Department of Church of Sweden into a process for adapting the structure in order to meet the new effectiveness requirements. Using both, Contingency Theory and Resource Dependence Theory as theoretical framework and a single case study as research strategy, this master thesis goes in deep into the description of the change of the structure of the International Department. This work shows how the different parts of the organization functions and what impact will these changes in the structure mean for the future of the organization. The analysis of the empirical evidence related to the theoretical framework shows that the organization responds to external demands through a more centralized structure than before.

The projects goal was to make an already existing indoor positioning system useful forthe average smartphone user. This was achieved by creating an Android applicationwhich, along with a running server, continuously presents the user with all the currentneeded information. It uses the graphics engine andEngine to create the graphical userinterface. The application was created in the development environments Eclipse andAndroid Studio..

Game balance can be considerd complex - there are many factors that play a role in the perception of balance. This thesis examines complexity, game theory and intution in an effort to disconver more about the perception of balance. The findings are that tactical and strategical choices that are presented for a player need to be interesting, not to complex and not to obvious. The importance lies in the estimation of the result that the player does when making a choice..

Technical products are becoming more and more complex, this means that the drivers, mechanics and service personnel?s need for assistance such as the service literature is increasing. In this degree project the focus is on the technical manuals of Scania?s Workshop Manual. Today, the information in the Workshop Manual consists of collaboration between text and illustrations.
