Attic adaptations and superstructures in tenement houses in city centres enjoy considerable interest, in spite of a rich offer of apartments available on the primary market. It can be assumed that a historic neighbourhood and a possibility to live in an old building is sometimes an attractive choice. Tenement houses built in the 1930s are particularly sought after by investors. Most frequently the...
The paper is an introduction to a broader study, aimed to define the rules of procedure for taking preservation activities in historic hospital architecture. It has, among others, to facilitate the modernization of historic hospitals necessary to carry out in accordance with the requirements set by the legislature, the latest medical technologies and contemporary doctrines and principles of conservation...
UNESCO Convention 1972, world heritage, a powerful opportunity to promote intercultural dialogue, promoting the UNESCO Convention 2003 for the Safeguarding of the Intangible Cultural Heritage and UNESCO Convention 2005 on the Protection and Promotion of the Diversity of Cultural Expressions.
In this paper the computer model of the cage induction machine taking into account magnetic non-linearity is presented. The model contains the mathematical model of the induction machine recorded as an S-function and the connecting blocs attaching the model from one side to the three-phase terminals of the supply system model and from the other to the system of mechanical model. Hence, Sim-Power-Systems...
In this paper Probabilistic Traveling Salesman Problem (PTSP) is considered and a hybrid algorithm is proposed, in which an evolutionary algorithm is combined with local optimization and parallelization techniques. Local optimization methods include 1-shift and 2-p-opt operators. Several basic variants of evolutionary and hybrid algorithms are experimentally tested and compared.
This paper presents an attempt to detect short circuits in double sourced electrical lines by discrete wavelet transform. First part of this talk describes a database preparation which is created by dynamic simulation base on model of double sourced transmission line. In order to choose the right model a comparison of two different represent of line has been made. In first one, transmission line is...
The paper presents the investigation results of the effectiveness of applying wavelet methods and the Wigner-Ville transformation in states monitoring of typical elements of the AC drive. As an example the electric drive system consist of the voltage inverter powering the squirrel-cage induction motor was showed. A case of complex mechanical load was also investigated. An influence of the decomposition...
It’s a beautiful game that enables us to create paradoxes, to reconstruct deformed images and to deform properly constructed ones. I t’s beautiful play in which imagination is the way of seeing reality and a form follows a vision, jumping by order of a randomly thrown dice.
As a response to the growing need for cheaper and more energy-efficient buildings, this paper presents a building system based on a heavy timber frame. The cost analysis to build a wall which meets the requirements for a passive building concludes that a prefabricated heavy timber frame is at the forefront of cost minimization. The recognized advantages of prefabrication can prove that this method...
In the paper the influence of colloidal silica addition with different amounts of organic resin in facade paints formulations on the change of water vapour permeability of hardened coatings was researched. The results were obtained by means of experiments. To quantify the ability of paint to diffuse water vapour, Sdfactor, defined as equivalent to the thickness of non-rotating air layer, was used...
This paper shows the results of impact that polymer additives with different chemical composition have on physical and mechanical properties of solidified mortar. During the research, modern polymer redispersed admixtures were used. An analysis of the changes was carried out using statistical methods and linear regression. It was found that the analyzed polymer admixtures affect the analyzed parameters...
This study presents the example of using extruded polystyrene for thermal insulation under the foundation slab of a building. Under the foundation slab of the thickness of 500 mm of a five- storey reinforced concrete building there was applied a layer of XPS of the thickness of 150 mm. The authors monitored the deformation of insulation under the load of the building from the moment of concreting...
The article addresses – based on an existing section of a tram line – the evaluation of the capability to substitute an existing train substation (as a civil structure) with several smaller ones. Taking into consideration the real estate prices and the shortage of available plots in the centers of larger cities, the localization of a substation building poses a significant location and budget challenge,...
Practical aspects of testing confined spaces, especially for the purpose of acoustic adaptations, are presented. The tests were carried out with use of prediction models, showing the possibilities of models that are used at present. Sound auralization, which is a reliable method for the assessment of sound signal quality and the acoustic conditions of tested rooms, is described. The basic criteria...
The purpose of my visit to New York was, on the one hand, a desire to get acquainted with one of the biggest agglomerations in the world, a city regarded by contemporary sociologists as a model example of the newly arising social phenomena, social trends and urban movements, and what’s more, one that is characterized by the greatest intensity of development and referred to by the leading sociologists...
This paper presents a method of forming detached houses architecture in modern times. Taking advantage of the inspiration on unrealized concept of building from the year 1924 has been indicated. The realization of Sagaponac House #4 from 2006 has been compared with the project of Brick Country House from Twenties of previous century.
The house near the crossing of Studencka Street and Garncarska Street, designed by Władysław Ekielski, was built over 100 years ago for Mr Wiktor Barabasz, director of the Conservatorium and founder of the Kraków Academic Choir, pianist and owner of the Grand and Upright Piano and Harmonium Storehouse. The two-storey building was made of brick and its three interior façades were given a finish with...
The paper explores theoretical and practical approaches to legal, social, economic, commercial and cultural issues, with reference to management strategies for the protection of monuments. These have semantic meanings and connotations which, in practical terms, raise a variety of issues concerning the care, protection, security, preservation and restoration of monuments, together with the preservation...
The spa towns situated in the valley of the river Prut in the Hutsul region preserved a little-known but extremely interesting set of historical urban and architectural layouts dating back to the first half of the previous century. Considering the progressing destruction of the multicultural landscape of this region, the need to identify and register them is becoming urgent. Neither the historical...
Breeding laboratory chambers require a wide range of indoor air parameters, which implies the need to use special equipment for air treatment and very accurate and fast automatic adjustment. The article presents the results of an experimental study conducted in the existing breeding chamber. The work is based on numerous observations as well as on-site measurement series of indoor climate parameters...
