Abstract The article considers the influence of the relief, river, and urban development on the formation of vortex structures in the atmosphere and the spread of pollutants in the city of Krasnoyarsk in winter. The weak influence of urban development on the appearance of large vortex structures over the river is shown. However, in the ground layer, it significantly changes the flow pattern and determines the character of the distribution of pollutants.

City centers worldwide are perceived as essential parts of the city, where city memories are preserved and its identity is expressed. They are planned to satisfy the functional requirements and pleasurable qualities of the city. Under the accelerating urbanization of the modern city, several challenges face these centers including demographic, economic, and environmental challenges. This requires a continuous and incremental urban development process based on clear strategy and action plans. Thus, this study focuses on urban development strategies of city centers, with a focus on Rafah city located in the Gaza Strip, Palestinian Territories. The geographic location of this city near the Palestinian-Egyptian borders makes it a promising commercial city at local and regional levels. Thus, the current situation of Rafah city center has been analyzed, and several development strategies have been proposed. This has been done through a field survey based on observation and a questionnaire directed to city center users. It has been found that there is a great potential of Rafah city center to be developed as a commercial center. In this regard, several strategies and required actions have been proposed in the fields of transportation, environmental quality, shopping activities, investment opportunities, and visual perception.

In today's world, when it is so important to use every piece of land for a particular purpose, both economically and ecologically, identifying optimal land use is a key issue. For this reason, an analysis of the optimal land use in a section of the city of Olsztyn, using the L-system Urban Development computer program, was chosen as the aim of this paper. The program uses the theories of L-systems and the cartographic method to obtain results in the form of sequences of productions or maps. For this reason, the first chapters outline both theories, i.e. the cartographic method to identify optimal land use and Lindenmayer grammars (called L-systems). An analysis based on a fragment of the map of Olsztyn was then carried out. Two functions were selected for the analysis: agricultural and forest-industrial. The results are presented as maps and sequences in individual steps.

Rapidly changing framework conditions for city development such as globalization, demographic trends, deindustrialization, technological developments or the increasing urbanization as well as the economic, social and political changes are profound and change our urban life. This leads, that the cities of tomorrow will differ essentially from today´s city principles. Therefore innovative, strategically wise and quick action becomes a criterion for success. Here, more than ever, local conditions and requirements must be taken into account as well as global framework conditions. The responsible parties have to set the course so that the “City” remains competitive and sustainable in the future. Therefore, innovation processes and sustainable strategies for dealing with the diverse and complex agendas of a city in dialogue with those who are responsible for it must be initiated and management systems established so that new things can develop continuously and systematically. This work illustrates how the boundaries created to manage and market future liveable and sustainable city destinations are the root of the practical and academic problems that trouble city management these days.  This paper aims to develop the new integrated Smart Urban Profiling and Management model, which presents a new integrated approach for city marketing as an instrument of sustainable urban development. In this way, comprehensive research was conducted to evaluate if the holistic city marketing concept that integrates elements of smart city strategies and adaptive management is a more suitable instrument and integrative process than conventional city marketing in order to improve the sustainable urban development. Therefore, in this work, the designed “Smart Urban Profiling and Management model” for city management introduces an alternative and holistic perspective that allows transcending past boundaries and thus getting closer to the real complexities of managing city development in dynamic systems. The results offer the opportunity to recognize the city and consequently allow to developing successful strategies and implementation measures. This study targets to contribute to this endeavor in order to produce new impulses and incitements in the city management field and shall provide a fresh impetus for a new understanding of city marketing as the initiator of development processes, mobilization and moderator in concerning communication and participation processes. This paper is written from a perspective addressing those responsible for the city- management, city- & urban marketing and development.

Since the advent of the second digital revolution, the exponential advancement of technology is shaping a world with new social, economic, political, technological, and legal circumstances. The consequential disruptions force governments and societies to seek ways for their cities to become more humane, ethical, inclusive, intelligent, and sustainable. In recent years, the concept of City-as-a-Platform was coined with the hope of providing an innovative approach for addressing the aforementioned disruptions. Today, this concept is rapidly gaining popularity, as more and more platform thinking applications become available to the city context—so-called platform urbanism. These platforms used for identifying and addressing various urbanization problems with the assistance of open data, participatory innovation opportunity, and collective knowledge. With these developments in mind, this study aims to tackle the question of “How can platform urbanism support local governance efforts in the development of smarter cities?” Through an integrative review of journal articles published during the last decade, the evolution of City-as-a-Platform was analyzed. The findings revealed the prospects and constraints for the realization of transformative and disruptive impacts on the government and society through the platform urbanism, along with disclosing the opportunities and challenges for smarter urban development governance with collective knowledge through platform urbanism.

Current imaginaries of urban smart grid technologies are painting attractive pictures of the kinds of energy futures that are desirable and attainable in cities. Making claims about the future city, the socio-technical imaginaries related to smart grid developments unfold the power to guide urban energy policymaking and implementation practices. This paper analyses how urban smart grid futures are being imagined and co-produced in the city of Berlin, Germany. It explores these imaginaries to show how the politics of Berlin’s urban energy transition are being driven by techno-optimistic visions of the city’s digital modernisation and its ambitions to become a ‘smart city’. The analysis is based on a discourse analysis of relevant urban policy and other documents, as well as interviews with key stakeholders from Berlin’s energy, ICT and urban development sectors, including key experts from three urban laboratories for smart grid development and implementation in the city. It identifies three dominant imaginaries that depict urban smart grid technologies as (a) environmental solution, (b) economic imperative and (c) exciting experimental challenge. The paper concludes that dominant imaginaries of smart grid technologies in the city are grounded in a techno-optimistic approach to urban development that are foreclosing more subtle alternatives or perhaps more radical change towards low-carbon energy systems.

Like in many other provinces, during the Habsburg period, the main point of orientation for Galicia was Vienna. This also applies to architecture and urban development. Galicia’s technical elite applied the theoretical and practical experience it gathered in Vienna to the towns and cities of this northeastern Crown land. Ignacy Drexler, born in 1878 in the Austro-Hungarian Lemberg, was a representative of a new generation of engineers and architects who did not necessarily have to spend time in the imperial capital to earn their spurs. Increasingly, besides the more or less obligatory stay in Vienna, other European countries became points of reference. Drexler did not live to see the realization of important aspects of his comprehensive plan for the city, but his ideas and the data he compiled were indispensable for the future development of his hometown. They shape urban planning in Lviv to this day.

- Unlike other great cities of Europe, Budapest did not experience any significant urban development before the nineteenth century, especially before 1867, the year of the foundation of the Austro-Hungarian Monarchy. After that, the city became the second pole, after Vienna, of this important European state. The capital of the Kingdom of Hungary grew through the use of various types of urban architecture and especially through a "style" that was meant to express Hungarian national identity. Architects, engineers, and other professionals from Hungary and Austria contributed to this process of modernization as well as many foreigners from Germany, France and England. The city's master plan - modeled after Paris's - focused on the area crossed by the Viale Sugár [Boulevard of the Spoke] was set on the Parisian model and so covered only certain parts of the city. The Committee on Public Works (1870-1948) played a leading role in putting the plan approved in 1972 - into effect in all aspects of urban planning, architecture and infrastructure.

<p>In 1840, the inauguration of the Great Western Railway in South England connecting London and Bristol, changed part of the outskirts of Bristol to a major railway hub and home of many rail-related activities. An area behind the station in between the railway, the River Avon and the Bath road, known as Temple Island, became restricted to rail use (workshops, depots or sheds) for more than 150 years, making it inaccessible and unattractive as the railway use decreased. The transformation of this area into a new centrally located neighbourhood is one of the most important urban development projects currently planned in Bristol. The new St Philips footbridge spans the River Avon, contributing to accessibility to the site and increasing the sustainable transport network of the city. The bridge, a 50m-span and 4-m wide steel beam with a forked geometry, seamlessly hosts a ramp for disabled and cyclists and a staircase to maximise functionality. The design approach to generate its shape was at the same time structural, aesthetical, and functional, innovatively solving a complex crossing problem.</p>
