Role kultury v procesu regenerace post-industriálního města / The Role of Culture in the Process of Regeneration of Post-industrial City

Milatová, Barbora January 2015 (has links)
The main subject of thesis The Role of Culture in the Process of Regeneration of Post-industrial City is to introduce the theoretical concept of regeneration of former industrial cities through culture and evaluate the impact of culture on the regeneration of post-industrial city. The first part is aimed at general issues of culture in regional development and attractiveness of the city, there are mentioned basic concepts related to the issue and defined trends in the development and regeneration of post-industrial cities through culture. The second part is aimed at the process of transformation of the city of Ostrava and contains an analysis of the current situation in the city. The City of Ostrava has prepared a strategic document presenting the revival of city through culture as a factor of improving its external image, but also a source of regional identity and the cultivation of the community. Empirical verification of the contribution of current policies to the regeneration and development of Ostrava city through culture is conducted through a questionnaire survey. The results show that the citizens of the city noticed visible changes towards the improving the quality of life in a city, however, if the city intends to continue in its successful strategy of regeneration, emphasis should be placed on citizen participation, their feedback and utilization of previously completed cultural investments should be improved by connection of existing cultural infrastructure.

Průmyslové dědictví a obnova měst: nové perspektivy pro čtvrť Atlampa v Mexico city / Industrial heritage and urban regeneration: New perspectives for the district of Atlampa in Mexico City

Guzmán Penella, Diego January 2021 (has links)
Industrial heritage and urban regeneration: New perspectives for the district of Atlampa in Mexico City Abstract in English The relationship between cities and industry has been the subject of research ever since the process of industrialization began in the 18th century. The interest around it has only grown once industry started leaving urban centers in the mid 20th century, forcing cities to evolve to fulfill new functions. This posed a challenge to urban planners and heritage professionals, who had to find solutions together to preserve important industrial sites without restraining the city from evolving. The present thesis explores the different approaches commonly used to address this challenge and analyzes their feasibility for the case of Atlampa, a historical industrial district in Mexico City that has stagnated for decades despite showing great urban potential and heritage value. The core of the thesis is a comparative study of former industrial districts with similar circumstances, which were identified through a diagnosis of Atlampa. The comparison analyzes the urban planning and heritage conservation approaches in each case and determines what could be a feasible and desirable strategy for the urban regeneration of Atlampa. Key words industrial heritage - urban regeneration - urban heritage -...

Experimentální podpora vývoje specifického integrovaného zařízení / Experimental support for the development of specific integrated equipment

Hrbáček, Jiří January 2021 (has links)
Regenerative heat exchangers are used in a wide range of industries and in the technical equipment of buildings. These heat exchangers play an important role in saving thermal energy and removing volatile organic compounds from flue gases. The theoretical part of the work deals with the division of regenerative exchangers into rotary and switching exchangers and the possibilities of their use. These types of heat exchangers are used in many applications, e.g. as a heat exchanger using waste heat to preheat the process gas (regeneration layer), or as catalysts to accelerate the reaction required to remove volatile organic compounds (catalytic layer), or as integrated equipment where both the regeneration layer and the catalytic layer. The aim of the diploma thesis is experimental support in the development of a computer program for the design of a specific integrated device. The program allows the calculation of the regeneration and catalytic bed, or both beds simultaneously, i.e. integrated equipment. The diploma thesis deals with the support of a mathematical model for the calculation of the regeneration bed. Pressure loss and heat transfer play an important role in the selection and subsequent calculation of a suitable bed. To calculate them, it is possible to find more available computational relationships that differ significantly in their accuracy. It is therefore necessary to select the most suitable ones for the computational model. The practical part of the work then deals with research, analysis, and assessment of the suitability of methods used to calculate pressure losses based on a comparison with the values measured on experimental equipment. Subsequently, the work deals with computational methods for determining the heat transfer coefficient of the packed bed. A significant part of the practical part deals with the modification of the experimental equipment for the verification of computational relations for the determination of heat transfer with measured data.

Technologie pro zvýšení propustnosti vod v kořenových ČOV / Technology to increase hydraulic conductivity of constructed wetlands

Pobořil, Jan January 2014 (has links)
Constructed wetlands are one of alternative solution wastewater treatment. Compared to conventional wastewater plants have many advantages. For example it´s technology saving construction, low operating costs, cleavability diluted wastewater and little or no need for electrical power. There are many publications dealing with Natural Ways wastewater treatment or even constructed wetlands. I decided to look for a thesis on one of the key processes – clogging bed media. The thesis is focused on ways to prevent clogging of bed media, mitigate the consequences and technology to increase hydraulic conductivity of constructed wetlands. The main test method is improving drainage parameters using pulsed filling and emptying of the bed media. This method is a very effective way to achieve quality requirements for effluent water from the treatment plant. Another test method is based on the injection of air into the media bed and sludge extraction using a specially modified industrial vacuum cleaner or pump.
