Nowadays, social software is in demand in very different settings. Managing relationships (e.g., social networking sites) and content sharing (e.g., photo sharing), but also collaborative working via the Internet became a widely accepted part of the social lives of people. Especially, collaborative environments provide platforms supporting users in creating and exchanging new ideas, material, and conducting discussions, but also in representing themselves by allowing for according profile management etc., cf. [KR07]. Supporting the users’ privacy in such interactive environments stands in sharp contrast to the objectives of collaboration. However, previous work has shown that different approaches may overcome this ostensible contradiction. One further approach is subject of this paper and consists of a differentiated role management. Accordingly, this paper describes the particular settings of applications shaping Privacy-Enhanced Collaborative Environments (PECE), for which a comprehensive role management has to be realized. The paper discusses the implications on the role concept resulting from the privacy-related settings and introduces a three-dimensional approach for roles in a collaborative environment.

The design goal is to propose future utilisation of large former industrial site containing heterogeneous set of manufacturing, service and dwelling buildings of different age and qualities. Also the site is heterogeneous itself – the old industrial grounds which are quite well maintained and long-term used apart from the new part – which has been conquered in hurry in the 60’ and now quickly disappearing in birch succession forest. The difference is reflected not only in site use design, but also in architectural solution of singular buildings. Buildings in the old part serv to the needs of Museum and its further activities and reacts to the style defined by Lichtenstein period architecture – power station and steam plant. Different pattern of each building aimed to utilization of the full building renovation approaches spectrum, ranging from steam plant conservation to analogical installation in the power plant to analogical reconstruction od wooden floor of the old furnance. Question of use and design of the blast furnances is far more complex and became the main topic of this work. The furnance approaches much more the LTO area than building one. It includes only two standard building spaces (threshers), the rest is taken by machinery or closed and inaccessible. The building character predestinates the furnances to become a archeologized monument. The design goal was to use the time still remaining for this unique structure with the intensity possible from the safety and functioning views. In the first stage, the furnance will house a community of artists, other creative or interested people functionally parallel to Cartuzian order monasteries. The housing units will be built in the powdery reservoirs, the common rooms in the threshers. A parallel to the chapel will be the furnance base – being accessible to the public. Every reservoir unit consists of two containers, winter garden and own garden space, every one is a miniature, but fully self sufficient unit surrounded by its own little universe, as the Cartusian idea requires. The main construction used will be the shipping containers, adapted for dwelling, put on suspended “cradles”. The unused rest of the reservoir space will be used as gigantic flower pot. In time, the roles of the spaces will change. The communication spaces of the former community house will become the only access to the furnance spaces and the corridor will remain half open as a view platform.

This project was made within the engineering studies and its aim was to design an assembly line to product assigned components of appropriate quality and quantity, using the technology of hot extrusion, both backward and forward. A series of technology steps was suggested, parameters necessary for individual operations were set and on this basis, adequate machines were chosen. The conclusion of this work contains technical-economical evaluation for the chosen options which expects the ten-year return with average production of 40 000 pieces.

The thesis deals with the comparison and selection of a suitable system of curing powder coatings. The work includes a literature review focused on the issue of powder coating. In the experimental part of the work will be carried out techno-economic analysis of the suitability of each technology for curing parts in a conventional and catalytic infrared oven.

The task of the diploma thesis named VBA and Maple Application on Process Engineering Problems is to show the possibilities of using these programming languages for various engineering tasks. Particularly the programming language Visual Basic for Application (VBA), which is a part of MS Office package, is very little used in practise. That´s why this thesis solves the complex task of a furnaces design process; the topic was reccomended by the supervisor prof. Ing. Josef Kohoutek, CSc. Specifically, the thesis deals with calculations of heat transfer and optimization of the height of extended surfaces of tubes in the convection section of process furnaces. The entire task is elaborated in VBA and runs in Excel. After entering the input information, the created program first calculates the size and heat output of the convection section, but it can also optimize the height of extended surfaces in different parts of the convection section and thus minimize investment costs.

The diploma thesis is dealing with selected parts of construction technology project of extension Vysoká pec no. 1 in Ostrava – Vítkovice. This thesis contains detailed elaboration of technological specifications for the construction of structural steel superstructure. For this phase is treated with a draft of mechanical report, inspection and test plan, dealing with traffic routes and itemized budget. There is also processed a proposal of building equipment which is the same for the entire implementation extension of Vysoká pec, a situation of building equipment, technical report of the object, the timetable for the entire project, ecology, health and safety.
