Chances of improving urban spaces appeal on selected examples
Get PDFThe dynamics of changes in urban spaces vary due to diverse local conditions and growth potential of individual urban settlements. The actions undertaken in order to improve the appeal of towns concern first of all improving the quality of public spaces, but they may also be of a broader range and aim at general growth based on the local natural environment conditions. Interesting examples of urban space transformations are presented by urban settlements with a well- defined leading function meaning unclear. Among such towns are those whose development was based on natural spa and curative characteristics stemming from the existing natural resources and specific climate conditions. The aforementioned resources – documented and used for a long time – need services of continuously improving quality, given the changing market situation and which is connected, this doesn’t work here but I’m not sure it’s needed anyway the accompanying high quality space
A new prototype of piezoelectric bending resonant transducer for analysis of soft tissues properties
Get PDFThis paper is devoted to a new piezoelectric bending resonant transducer prototype dedicated to the characterization of the mechanical properties of soft tissue. A general description of the actuator’s structure is presented including the basic principles of the measurement. The chosen geometry of the prototype is discussed and compared with the existing version. Constitutive equations are presented for the active and passive layer of the cantilever transducer. The prototype is verified by means of finite element method analysis. Results of the static and modal analysis are presented and discussed
Determination of characteristic flow values downstream of the Racibórz Reservoir using Monte Carlo methods based on copula functions
Get PDFThis case study of the Racibórz reservoir discusses the application of a determination method of characteristic flow values below retention reservoirs. The study describes the selected theoretical foundations, the individual steps of the Monte Carlo (MC) method used to generate hypothetical flood wave hydrographs, and the results of simulations leading to the determination of characteristic flow values below retention reservoirs. The method is based on probability density functions for a multidimensional random variable obtained using copula link functions. The results of the analyses are represented in tables and graphs. The results of the simulation analysis are presented for comparison purposes, assuming a constant and a variable time for the hypothetical base flood elevation
Playing at barracks or playing with barracks?
Get PDFThis article attempts to organize the activities that have been carried out in the recent decades in relation to historic barracks located in Poland, in comparison to the analogous processes taking place abroad. It presents examples of old post-military complexes whose function has recently been changed. There are two approaches to the adaptation of these buildings: enclosing in the historic context (“playing at barracks”) and contrasting with the historic background (“playing with barracks”)
Games of architecture in the recent past
Get PDFArchitectural design takes place in a certain cultural space. I f the space is not expressive enough for the artist, observer or passer-by, architects create their individual worlds where original artworks shaping space appear. And the audience accepts it with understanding
An attempt to evaluate the application of 3d scanners in construction diagnostics and tests
Get PDFFor over a decade there has been a rapid development of technology in the construction of 3D scanners, resulting in increased precision, speed and reliability. The scope of their application has also been continuously extending. This paper describes possible applications for 3D scanners in construction measurement and evaluation. The uses described include measuring concrete surface roughness and surveying architectural details
Attractiveness of the Manhattan district
Get PDFThe urban space in today’s world has become, in many cities, “rootless” and “alienated”. “Non-places are all those spaces, which are the antithesis of home, domesticated space, well-oriented, almost temple-like, personalized, with their own history and accumulated memory. In the space of home people had names and surnames, had well-defined identities” [20, p. 10]. “Impersonal lone crowd” [12] in public spaces leads to a dangerous phenomenon of creation of closed-off enclaves of people who have interactions only within them and control one another. It leads to fear of new challenges, emotions, passions, social life. It also paves the way for depopulation of cities and lack of eagerness to live in them, because cities become less interesting. The phenomenon of “attractiveness of cities” and city space pertains to identity and social distinctiveness of places, friendly neighborhood, good access to communication and shopping, services, culture and recreation. This characterizes Manhattan – the New York district that never sleeps. It is vibrant with life and energy, with an infectious atmosphere, thereby rendering it one of the most attractive in the world. The emotions that it evokes forever inscribe themselves in our memory
Sustainability and modesty: a permanent challenge for conservation architects
Get PDFNew needs in society ask for new approaches and new criteria in cultural heritage. Still, they brought new solutions which are not always consistent with those of Venice Charter (1964) or Krakow Charter 2000. We inherited everything around us, including the landscape and all semantics related with that environment. In the eternal and universal dilemma between progression or conservation, conservation should prevail, as we are conservators; yet sometimes progression has to be part of it if we can guarantee by this way the rescue and survival of the monument or heritage. The article aims at presenting the answers for the challenges of today’s conservation of cultural heritage, in the modified and diversified society- both linguistic and regarding architectural practice. Thus the author proposes the approach marked by sustainability and modesty and also gives three definitions and three categories of heritage (of historic or artistic value), allowing for a variegated approach – in the decreasing scale of restraints concerning change or transformation
Possibility of existence of torsional vibrations of beams in low frequency range
Get PDFThis paper discusses the problem of the existence of torsional natural modes in the low frequency range for a beam with a rectangular cross-section with different ratios between width and height and different lengths. The rectangular type of cross-section is chosen because of practical applications to describe the vibrations of some turbine blades. The analyses were conducted by applying an analytical model, but were verified using the finite element method
Spa resorts in the age of knowledge-based economy
Get PDFSpa resorts with a high quality environment, both in the natural and cultural sense, are attractive places for locating knowledge-based economy infrastructure. The article discusses several examples of technology parks and centres located within spa towns and presents the strategies which spa resorts may apply to boost their competitiveness and diversify the services they offer. Building partnerships and networks between research units, linking businesses and administration, developing services and technologies connected with balneology treatments and tourism as well as implementing green technologies open up new opportunities of growth for spa resorts
