The creation of sustainable and safe environments nowadays moves more and more into focus for urban planners and architects. Cities should be designed in a way to contribute to social cohesion, shaping an inclusive environment and focusing on the wellbeing of its citizens. Nevertheless, these processes can be undermined by public crime and the fear of crime, which is not only affecting aspects of personal safety but also affecting the people’s behaviour. Reasons why criminality occurs are manifold, impacted by a dynamic set of socioeconomic, demographic, personal but also environmental aspects. In recent years especially the impact of factors related to urban and environmental design respectively planning received rising attention in the field of crime prevention. However, the implementation of strategies regarding ‘crime prevention through environmental design’ or ‘designing out crime’ is still in its early stage in Sweden.   This study aims to investigate spatial and temporal patterns of public crime for the case of Umeå in order to identify potential risk areas, which could receive particular attention regarding crime prevention through environmental design (CPTED). In this sense a GIS based spatial analysis had the aim to detect statistically significant hotspots of crime and furthermore to assess the development of these hotspots over time. In order to understand the nature of public crime and criminal behaviour in Umeå in a more holistic way, also temporal aspects regarding the occurrence of crime were analysed. One particularly vulnerable neighbourhood was examined with a qualitative field observation regarding the principles of crime prevention through environmental design in order to assess in which way the built environment is designed and suited to prevent and deter criminality.   Umeå displays rather clear patterns of higher crime activity, assigned to seasonal, weakly and daily periods, which are connected to higher activity in the public space. Also from a spatial perspective certain patterns are detectable with a higher vulnerability for crime at spots which generate higher activity such as shopping areas or neighbourhoods with nightlife and transport hub functions, and in general neighbourhoods with a higher building density. The neighbourhood of Ålidhem displayed thereby a high concentration of criminality, marked as a constant or even intensifying hotspot for the entire period of investigation. The results of the field observation regarding principles of CPTED are especially indicating a lack of maintenance and furthermore the street and building layout is contributing to disorientation. On the other hand, the area is in most cases well equipped for natural surveillance and provides a high amount of locations for leisure and recreation in order strengthen social cohesion.

This thesis project explores how interactive technologies can facilitate a sense of social connectedness with others whilst remotely located. While studying the way humans use rituals for emotional management, I focused my interest on the act of commensality because it is one of the oldest and most important rituals used to foster togetherness among families and groups of friends. Dining with people who do not belong to the same household is of course hard during a global pandemic, just like many of the other forms of social interactions that were forcibly replaced by the use of technological means such as video-chat apps, instant messaging and perhaps an excessive use of social networking websites. These ways of staying connected, however, lack the subtleties of real physical interaction, which I tried to replicate with my prototype system, which consists of two sets of a lamp and a coaster which enable to communicate through light and tactile cues. The use of such devices creates a new kind of ritual based on the simultaneous use of the devices by two people, thus enabling a new and original form of commensality that happens through a shared synchronized experience.

The topic Modern Approaches to Designing Electrical Equipment with a Focus on Railway Construction responds to the decision of the Government of the Czech Republic to introduce the BIM method for government over-the-counter contracts from 1 January 2022. The government evaluated the BIM method as an effective tool for digitizing the construction industry. The diploma thesis deals with the method of designing high-current equipment, technologies and distribution on railways according to this new method. The work summarizes information about the present method of design, used high-current electrical equipment on the railway, the near and distant future of railway operation, the organization of administration and maintenance of equipment. It discusses the principle of the BIM method and basic software solutions supporting design activities according to this new method. The Promis.e software published by Bentley is also described in detail, which supports the design of electrical equipment for linear structures according to this method. The BIM method is a means of fulfilling the essence of Construction 4.0. It uses uniform data formats, a common data environment, working with non-graphic information. In the second part of the diploma thesis, the drawing documentation for the sample project of high-current distribution of the railway station was prepared. It was first created using AutoCAD software. After that, the sample project demonstrates the basic principles of the BIM method using Promis.e software. Furthermore, this project is evaluated, both methods of design are compared. The procedure of introducing the BIM method for the design of electrical equipment in a specific design company is proposed and other possible steps in working with the Promis.e software are discussed. The way of creating a and adding element libraries is described. At the end of the diploma thesis it is stated that to successfully master the design work according to the BIM method, it is necessary to have experience with design work in the field, know the principles of the BIM method, choose a suitable software solution, continuously and thoroughly manage these tools and train staff. Under these conditions, it will be possible to make full use of the potential of the BIM method.

This thesis deals with design of hydrostatic drive for multipurpose loader and tool carrier DAPPER. At the beginning is research of different basic concepts and modern solutions to the problem, aided by a detailed description of competitive machine in the same performance category. Extensive comparison with other producers is included in the annexes to this thesis. Furthermore, a theoretical driving characteristic and its appropriateness is examined further on the basis of two model situations. The calculations of the individual components of the hydraulic circuit precedes drive kinematics analysis of articulated machine frame, on it final conception of hydrostatic drive is chosen. Firstly hydromotors and hydogenerator are chosen on the grounds of calculations then hydraulic hoses, filters and flow divider. Next chapters are aimed to calculations of hydraulic losses and thermal calculation of hydraulic circuit. Final part deals with introduction the final characteristics of drive. The practical parts of the work are assembly drawings with main power components and hydraulic schematic of drive.

The electric vehicle industry is under rapid development and the fleet of chargeable cars in society is increasing fast. As a result, a high demand for public chargers has emerged. Simultaneous to the expansion of the electric vehicle fleet and charging infrastructure the power grid is occasionally highly strained. Additionally, factors like cities expanding and the digitization of society also have a large effect on the power grid. This master's thesis investigates the characteristics of electric vehicle users and presents a prototype of an information display for electric vehicle charging stations. The design is is based on the user studies and founded in theory about sustainable user behaviour with the goal of encouraging behaviours that minimize the strain on the local power grid of Uppsala. It concerns the research topic of how to design for sustainable behaviour and address research questions of how to design electric vehicle charging station information to communicate multiple charging alternatives to a broad variety of users. The work reveals that electric vehicle users suffer from the charging infrastructure being underdeveloped, feel frustration towards payment solutions available and lack information regarding electric vehicle use. Also, electric vehicle user's common passion for tech and environmental consciousness are revealed in the study. These facts are used as the foundation for the mobile application design prototype suggested.
