Abstract

The explosive rise of wireless services necessitates a network connection with high bandwidth, high performance, low mistakes, and adequate channel capacity. Individual mobile users, as well as residential and business clusters are increasingly using the internet and multimedia services, resulting in massive increases in the internet traffic demand. Over the past decade, internet traffic has grown significantly faster than Moore’s law predicted. The current system is facing significant radio frequency spectrum congestion and is unable to successfully transmit growing amounts of (available) data to end users while keeping acceptable delay values in mind. Free space optics is a viable alternative to the current radio frequency technology. This technology has a few advantages, including fast data speeds, unrestricted bandwidth, and excellent security. Since free space optics is invisible to traffic type and data protocol, it may be quickly reliably and profitably integrated into an existing access network. Despite the undeniable benefits of free space optics technology under excellent channel conditions and its wide range of applications, its broad use is hampered by its low link dependability, especially over long distances, caused by atmospheric turbulence-induced decay and weather sensitivity. The best plausible solution is to establish a secondary channel link in the GHz frequency range that works in tandem with the primary free space optics link. A hybrid system that combines free space optics and millimeter wave technologies in this research is presented. The combined system offers a definitive backhaul maintenance, by drastically improving the link range and service availability.

Abstract

The aim of this paper is to look at the quantitative dimension of public space resources in Polish cities, a comparative analysis of these resources, determining the share of public space in the urban spatial structure and referring this structure to European cities. The concept of ‘public space resources’ has been introduced, and is defined as those areas in the city that fulfill or can fulfill the functions of public space. This concept, and then the proposal of its operationalization, aimed to draw attention to the spatial and physical aspects of public space, which would allow to broaden and supplement social approaches in the study of public space. The quantitative approach to public space proposed in the paper also enabled a comparative research to assess the role of public space in the structure of Polish cities in a more objective manner and refer it to European cities.

Abstract

The following article presents a selection of the most interesting examples of transformations of public space in towns and cities of varying sizes in Lesser Poland which were aided by European grants obtained from the pool of EU funds, with special attention to the Lesser Poland Regional Operational Programme (ROP) an also the Rural Development Programme (RDP) in the years 2007-2013. The presented findings are of a preliminary nature and are phase in the wider studies being conducted by the Author covering the multifaceted transformations of public space that have taken place and are taking place in Poland with the aid of European funding. The aim of these studies is an overall evaluation of how, in specific planning periods, the joining of the European Union and the possibility of taking advantage of Western experience, as well as financial support, influenced and influence today the transformations of public space in Polish towns and cities, and their influence on people’s thoughts and perceptions of such space.

Abstract

This paper brings up elementary problems related to the creation of friendly public spaces in residential complexes as the main places of social integration. Contemporary social transformations are reflected in a new, intensified usage of public spaces which – offering more and more possibilities of satisfying human needs in the field of social contact, knowledge, recreation, stimulation etc. – provoke people and their activities to transfer “life” from a private space to a public space.

Abstract

The article concerns problems with shaping contemporary housing estates. By analyzing housing structures designed in recent years, the aim was to demonstrate the importance of creating the continuity of public spaces in order to achieve places seen as attractive and presenting features of high quality urban space. Essential for the research is the question about the conditions which should be fulfi lled when creating the ideal residential place which then leads to a series of answers. These included indicating a good location with functional and aesthetic urban/architectural solutions. Environmental issues are important as well. Regardless of whether it is a multi-family dwelling or a single family house, a good neighborhood and its location in a well-connected place with necessary basic services within walking range are important. It is also signifi cant how the public space was shaped and whether a natural network was created. Due to factors such as the specifi city of the structure’s location in the city and diff erent surfaces of designed estates, as well as the variety of residential buildings being constructed, it is often diffi cult to assess them unambiguously. Importantly, this assessment also includes social and economic aspects as well as technical issues. However, by using multi-directional research it can be noted that the forms of public spaces within housing complexes play an important role in the creation of high-quality structures, perceived as attractive not only by the residents.

Abstract

The main objective of the article is an attempt to indicate factors which determine the image of a city as a good place to live as well as to reveal the ways in which they affect the citizens’ quality of life. In order to do so, the author selected the city of Gdynia which is perceived as the best city to live in by its citizens. Among the most important factors determining the quality of life in general there are: the scale of a city, local identity, public spaces, symbolic places, housing environment, perception of a place, personal satisfaction of a place where a particular person lives, urban policies as well as presence and activeness of local leaders. The article presents the results of a social study carried out by the author herself during two periods of time – in 2004 and 2014 as well as the results of the Social Diagnosis 2015.

Abstract

The article is an attempt to analyze the spatio-pedagogical discourse of the German social pedagogy. It represents only a fragment of reflection on the turns in paradigm of place/ space (spatial turn), as pedagogical terms. & e authors seek to answer the question what is the space and place, and what concepts in the field of reflection on the place/space run in the German social pedagogy. The text introduces, inter alia, the relational concept of space developed by Martina Löw, duality of space and the concept of spacing. Active creation of urban space, the spatial dimension of the relationship and its dynamics are subjected to discussion. The article presents critical approach to the notion of transdisciplinary space, and space-oriented social work. Finally, it provides the incentive for in-depth, international analyzes of spatio-pedagogical theories.

Abstract

In this paper a small time local controllability, naturally defined in a configuration space, is transferred into a task-space. It was given its analytical characterization and practical implications. A special attention was put on singular configurations. Theoretical considerations were illustrated with two calculation examples. An extensive comparison of the proposed construction with the controllability defined in an endogenous configuration space approach was presented pointing out to their advantages and disadvantages.

Abstract

Commercial functions are very important to the process of urban revitalization. Various commercial forms of trade, such as markets, marketplaces, cloth halls have enriched the public spaces of cities over the centuries. Over the last 25 years of the free market in Poland, we have observed deformations within the urban structure caused by new types of commercial functions. The attractive functions of urban malls and shopping centers, which are usually placed inside, cause the degradation he streets located outside. Shopping centers, spread within the city and isolated by parking areas from pedestrian networks, contribute to the growth of inner peripheries. The fluctuations of the global economy should lead us however, to the delimitation of commercial functions, especially the largest ones. The proper relations between these commercial areas and the beautiful landscape of the city can be used as an element of building the city's image. Ventures within the historical city centers require the development of new instruments which would allow us to protect existing values.

Abstract

A meadow, a flowery meadow, a clearing, a lawn – smoothly trimmed, flat and recessed, a grassy pathway – these are elements of gardens that have been known for centuries, used in different styles and different types of gardens, including in public spaces. Pratum commune, commons or grassy mounds are the landmarks of the landscape of many a city, both currently and throughout history. Decorative grasses, such as pampas, Miscanthus or Pennisestum started to be used in garden compositions in XIX-century England. Initially more so due to their peculiarity than beauty. However, it was naturalism that gave rise to the wider use of grasses in gardens and parks in various places of the world and gained many propagators, including W. Robinson, J. Jensen K. Foerster and P. Oudolf.Grasses are currently often designed by landscape architects in urbanised spaces. They are employed both in geometric and freeform compositions. Their texture and delicate colour create a background for more expressive plants. They often constitute the key element of naturalist layouts, and the use of domestic species aids in preserving biodiversity and recreating the domestic landscape. Many of these current projects have been discussed in magazines and subject literature and have received awards in competitions. This review article is devoted to this subject.

Abstract

The matter of the accessibility of the human living environment and adapting it to (often highly diverse) user needs is not new, yet not all of its fields have had proper models and universal design guidelines prepared for them. Open learning and recreation zones that are accessible to all users and which correspond to their various needs are a sign of a new way of thinking about the role of urban spaces. This paper is intended to both familiarise readers with a model solution — Darrell’s Dream Boundless Playground and formulate guidelines that could aid in the construction of new, barrier-free spaces of this type.

Abstract

The article describes the relationship between the local community and the primary school considered as “place” within the meaning derived from the book by yi-Fu Tuan “Space and place: The perspective of experience”. The article compares the cases of two schools in the city of bielsko-biała (the city has a population of 175 thousands inhabitants). One school is overcrowded, yet its future existence has been secured. The second school, however, was first transferred to another location and it eventually went into liquidation in 2012. The article demonstrates then underlying reasons and consequences of losing the school as place. Moreover, it indicates potential problems emerging in such cases altogether with a set of possible solutions.

Abstract

The concept of place has been present in human geography for almost half a century. The human geographers looked for the answer about genesis of place category in different sociological or psychological aspects with the basis of space dimension. In last two decades a few of them referred that idea to communication processes. Inspired by the views expressed by the latter group of scientists, we are asking: how is creating a place? We put forward thesis that a special type of place making is social communication that works continuously on the principle of the palimpsest of overlapping meanings through messages arising in several dimensions. Our assumption is that every place is creating (overwriting) a social subject – an individual or a group, that will build communication in three dimensions: within a space/place (W), about a space/place (A), and/or between people and a space/place (B).

Abstract

The Author tries to “think out of the box”, presenting “Sponsalia ex hoc mundo” (“Hand fastening out of this world”). The title reflects the view that the outer space sciences and the sea sciences are analytically separable, but practically interlinked. It might be observed in the context of space technology and satellite technics, a new system of management and government, as well as a new system of law and policy. Nowadays, the outer space infrastructure (the use of artificial Earth satellites for Direct Television Broadcasting, communications, remote sensing, navigation, military missiles) affects infrastructure of our Planet, including maritime infrastructure. There is, therefore, the need for a new face of integrated system of science and practice.

Formation the local identity in the “thematic” Rural Renewal, The article aims to determine the main conditions for the development of rural thematic areas in the context of Rural Renewal. Against this background, the authors attempt to explain the mechanisms governing the discussed process and their effects. In view of the above, the focus was on presenting mechanisms for the development of processes that lead to the flowering of this idea (an anatomy of success – the case of the village of Sierakowo Sławieńskie) and those that slow down or completely limit this development (anatomy of failure – the case of the village of Lubcza).

Abstract

In the paper author discusses problems related to the leading role of architectural structures, as a part of the creating process within contemporary urban space. Architectural objects establish a continuous dialogue not only with their surrounding space, but also between each other. In this relation, the first plan comes with two factors, determining all spatial and functional solutions: the place in which a given project is localized and the time in which the urban designer came to the architect to create his plan. Based on the analysis of own projects and urban and architectural realizations, the author proves that the architectural dialogue in urban space must be respected in the context of the place and the time, but also in the creators moral responsibility. This responsibility is defined by consequences of design decisions not only for the urban space itself, but above all, for people and their coexistence with the space. For designers it reveals a necessity to comply principles of ethics and professing the value system in order to taking care of the urban space not only three-dimensional, but also “existential”.

Abstract

In the Act on Revitalization of 9 October 2015, for the first time in Poland, the legal act introduced the necessity to apply the principles of universal design (Article 3 paragraph 2 point 3). The practice of investment processes in crisis areas shows that the requirements set out in the Act are not properly implemented. Regeneration processes require attention to improve the quality of life of residents. The article presents issues related to the implementation of universal design principles during revitalization processes. There is a noticeable lack of interest in this issue despite the fact that it is one of the three tasks set before local governments in the Revitalization Act, after social participation and support for people at risk of exclusion in the area of housing. The reasons for this state should be seen in a small knowledge of the issue, deficiencies in the educational process of designers and poor control on the part of local governments and central authorities. This is due to conservation conditions, which often misinterpret the right to protect cultural heritage. The self-government as its own task should guarantee the possibility of using the positive effects of the revitalization process, in particular the implementation of residents’ rights to an independent and dignifi ed life, which is required by the UN Convention on the Rights of Persons with Disabilities.
