Abstract

The paper features some aspects of providing information security and business continuity to public administration by means of an integrated computer-aided management system OSCAD. The system is based on international standards ISO/IEC 270001 and BS 25999 (ISO 22301). First, the significance of information security and business continuity issues in public administration was presented along with a short introduction to the applied standards. Then the possibilities of the OSCAD system were discussed together with the examples how the system can solve the problems encountered by public administration.

Abstract

As a central goal of the energy transition in Germany, the share of renewable energies is to be increased to over 80% by 2050. Due to fluctuating wind conditions or the day-night cycle, storage systems must be integrated into the supply grid for a continuous regenerative power supply from wind and solar energy. In addition to pumped storage systems, batteries and Power2Gas approaches, compressed gases (optimally air) can also be used for this purpose. The aim of the research and development project presented is to develop such a storage unit with the best possible efficiency and long service life. To this end, basic calculations were first made on possible efficiencies depending on the assumed changes in the state of the working gas. Furthermore a piston compressor for compressed air generation was investigated experimentally with regard to its efficiency. In addition, the compressor was modelled and simulated in a corresponding software. Thus, on the one hand, the efficiency of the existing piston compressor could be determined experimentally and, on the other hand, the simulation model could be assessed with regard to its suitability for the purpose of simulation-based optimization. Measures to increase efficiency can be derived from the results. In addition, it becomes possible to forecast the achievable overall efficiency of such an energy storage system with compressed air.

Abstract

New methods for identifying the material properties of planar objects as a result of measurements by the eddy current method are proposed. The methods are based on the latest surrogate strategies and advanced optimization techniques that improve efficiency and reduce resource consumption of problem solutions, and balance computational complexity with the accuracy of the results. High-performance metamodels for global surrogate optimization are based on deep truly meaningful fully connected neural networks, serving as an additional function of accumulating apriori information about objects. High accuracy of the approximation of the multidimensional response surface, which is determined by the “exact” electrodynamic model of the testing process, is ensured by performing calculations according to the computer design of a homogeneous experiment with a low weighted symmetric centered discrepancy. The results of numerical experiments performed for full and reduced dimensional search spaces, which can be obtained by linear transformations using the principal component method, are presented. The verification of the methods proved their sufficiently high accuracy and computational performance.

Abstract

International scales describing the intensity of tornadoes are investigated along with reports from the Polish Government Security Centre on all types of wind storms in Poland. Then, collected tornado reports for the years 1899–2019 in Poland, a set of the annual maximum gust wind speeds measured at 39 meteorological stations from 1971 to 2005 (35 years), descriptions of Poland’s strongest wind storms in the 21st century, estimating the risk of significant strong and extreme winds in Poland, and classification of maximum wind speeds by Lorenc (2012) are presented. Based on these data, i.e. measured and estimated wind speeds, this paper proposes two separate intensity scales to categorize synoptic, thunderstorm, and downslope winds (in the Tatra and Karkonosze regions), derechos, tornadoes, and downbursts, i.e. all types of wind storms. These scales are simpler than the one put forward by Lorenc (2012). These two scales cover a range of maximum wind speeds from 20 to 90 m/s. This proposal is only applicable to Poland. Other countries may determine whether it applies to them.

Abstract

At both state and federal level in the USA there exist various instruments to protect the maritime environment. The general conception of protection is to base it on the construction of a protected area. In 2006, there existed at least 500 areas under protection. These were created by more than 100 federal and state administrative offices. The development of environmental protection law is moving in the direction of an appropriate management of the Atlantic, Pacific, and Arctic Oceans. In US legal doctrine it is stressed that US jurisdiction extends up to 200 nautical miles from the US shoreline. Coastal states have a right to regulate the legal status of the first three nautical miles of the oceans that touch their coasts. The doctrine of public trust is derived from common law. Its essence is the recognition that certain natural resources - the waters and bottom of coastal seas and large lakes - are of considerable importance for society as a whole. They cannot be given into private hands and controlled by private owners. The concept of protected maritime areas first emerged during the meetings of the World Congress of National Parks in 1962. Protected maritime areas on a federal level take various forms: maritime national reserves, national parks, national areas for wild life refuge, national natural monuments, areas o f fishery management, and threatened habitats. The author of the article discusses the legal acts of Presidents Clinton and Bush relating to maritime protected areas. The establishment of such areas is consistent with tendencies observable in the UN.

Abstract

This paper discusses heritagisation, a key concept in critical heritage studies. The author differ-entiates the sources and meanings of this term within various heritage discourses. First and foremost, the ambition of the paper is to propose an appropriate translation of heritagisation into Polish, one that embraces all the negative aspects of this process.
The concept of heritagisation was introduced in the 90s and then later adapted by scholars representing critical heritage studies. Originally, the term was used to signal the dangers linked to the administrative processes of heritage‑making: gentrification, commercialisation, monetisa-tion and flattening the meanings of monuments and architecture from the past. The term was critically examined at the beginning of the 21st century, when scholars used it to describe the accumulation of heritage that is insufficiently protected. Nevertheless, this concept, migrating from discipline to discipline, also gained a positive meaning connected to the adaptation of heritage. In this paper the author discusses the differences between negative and positive her-itagisation. The author identifies the differences between discourses, and explains how the concept is used within various fields of study. Last but not least, the author proposes a non‑literal translation of heritagisation into Polish, which should embrace all the meanings of the concept framed by critical heritage studies theory. Finally, the author applies the concept to a case study: the history of Pavilion Powiśle/Syreni Śpiew.

Abstract

During two seasons of archaeological investigation, in 2014–2015, on plot 168 in Puck, a total number of 29 numismatic items were discovered: 28 single coins and one token. The chronology of discovered coins is quite wide: coins from the 14th to the 20th century were registered, among them five medieval coins. In analyzed collection the most interesting are coins of the Teutonic Order — firchens and bracteates; moreover we have Polish and Prussian coins and also Tyrolean and Bavarian coins.
