Opis:
Tematyczne szlaki kulturowe cieszą się coraz większym zainteresowaniem i popularnością. Nie tylko przyciągają uwagę znawców i ekspertów, lecz także stanowią interesującą i oryginalną ofertę turystyki kultury wysokiej. Poruszona w artykule problematyka obejmuje zagadnienia dotyczące utworzenia Szlaku Kultury Łużyckiej w Powiecie Będzińskim, składającego się z miejsca byłej osady obronnej, byłych cmentarzysk, punktów osadnictwa, miejsc różnych znalezisk luźnych. Przedstawione zostały plany i pomysły związane z utworzeniem szlaku oraz zaprezentowano dotychczasowe działania koncepcyjne w kwestii tworzenia alternatywnych typów szlaku. W pracy wykorzystano metody miękkich badań operacyjnych, ukierunkowane na wspomaganie procesu definiowania problemu decyzyjnego przy pomocy algorytmu PrOACT i jego strukturyzacji na potrzeby wielokryterialnej oceny. Zaprezentowano metodę SMART w analizie decyzyjnej dotyczącej najefektywniejszego wyboru spośród różnych typów szlaku: tradycyjnego, niewytyczonego, wirtualnego czy też questingowego.
Thematic cultural routes become increasingly popular and they are object of interest. They attract not only specialists and experts, but they also provide an interesting and original offer of high culture tourism. The topic covered in the article concerns the creation of the Lusatian Culture Route in District of Będzin consisting of the site of the former defensive settlement, former cemeteries, settlement points, places of various loose finds. Plans and ideas related to the creation of the route have been presented and the existing conceptual activities on the creation of alternative types of the route have been also presented. The purpose of the paper is to identify the possibility of using an analytical approach to identify the problem and objectives of decision-makers (authorities of local government units) whose competence is related to the creation of such a cultural route. In this paper, there will be used „soft” operations research methods which are directed to support the process of defining a decision problem using the PrOACT algorithm and its structuring for multicriteria evaluation. The SMART method will be presented in the decision analysis for optimal selection of different types of the route: traditional, not marked out, virtual or questing.

Opis:
The study is devoted to the study of strategic vectors for the development of recreational lands. It is proved that in the current state of the recreational lands of the EU countries there are certain obstacles on the way to the sustainable development of the respective territories. The recreational sphere is deprived of the possibility of balanced development due to the problems of inefficient use of the lands of the respective territories. These lands cannot provide both the need for recreation and the necessary protection and restoration of the environment due to the negative anthropogenic impact. The author’s definition of the term "land strategizing" is given. The components, functions, subjects and the effect of the implementation of the strategy of recreational territories are determined. The proposals for the implementation of the land strategy process using the methodology of foresight forecasting of recreational land use have been developed. The scientifically grounded stages of Foresight forecasting and methods of their implementation from the set of Foresight forecasting methodology are proposed. The logical-structural scheme of land planning for recreational territories based on the foresight methodology is presented. Also the procedure for the foresight methodology implementation in the direction of sustainable management of recreational land use is proposed.

Opis:
Purpose: The main purpose of the work is to present the impact of standardisation methods on the ranking results. The second purpose of the article was to present Warsaw’s position in comparison with the capitals of countries from the Eurozone. Design/methodology/approach: Major European cities were assessed using Eurostat data. The proprietary Smart City Index (SCI) indicator is proposed for the study, referring to six areas of Smart City assessment. Two measures are indicated in each of them. The first is an objective measure, while the second is a subjective measure, based on the opinion of the city’s residents about the situation in the city, or their own situation. Building rankings of the cities, following normalisation methods were used and compared: unitisation, unitisation with zero minimum, normalisation in range [-1, 1], classical standardisation, Weber standardisation and two quotient methods. Findings: The best results were obtained for the classical standardisation. For this method we obtained the smallest number of consistent positions in rankings and the minimal maximum of distance between the positions in rankings. The position of Warsaw as a city in 16th position (20 of all) was confirmed regardless of the standardization method used. Originality/value: There is proposed an original method to assess cities based on Eurostat data. This method allows construction of Smart City ranking. The main value of the work is that the classical standardisation is recommended to transform the original values of individual indicators.

Opis:
A new solution to the problem of frequency estimation of a single sinusoid embedded in the white Gaussian noise is presented. It exploits, approximately, only one signal cycle, and is based on the well-known 2nd order autoregressive difference equation into which a downsampling is introduced. The proposed method is a generalization of the linear prediction based Prony method for the case of a single undamped sinusoid. It is shown that, thanks to the proposed downsampling in the linear prediction signal model, the overall variance of the least squares solution of frequency estimation is decreased, when compared to the Prony method, and locally it is even close to the Cramér-Rao Lower Bound, which is a significant improvement. The frequency estimation variance of the proposed solution is comparable with, computationally more complex, the Matrix Pencil and the Steiglitz-McBride methods. It is shown that application of the proposed downsampling to the popular smart DFT frequency estimation method also significantly reduces the method variance and makes it even better than the least squares smart DFT. The noise immunity of the proposed solution is achieved simultaneously with the reduction of computational complexity at the cost of narrowing the range of measured frequencies, i.e. a sinusoidal signal must be sufficiently oversampled to apply the proposed downsampling in the autoregressive model. The case of 64 samples per period with downsampling up to 16, i.e. 1/4th of the cycle, is presented in detail, but other sampling scenarios, from 16 to 512 samples per period, are considered as well.

Opis:
Magnetorheological materials belong to the group of the so called intelligent materials. Their rheological properties can be changed in a large range using an external magnetic field. That is why they fmd ever growing application in modern technical equipment, among others in controlled dampers, clutches, sensors etc. In the paper, a numerical strength analysis of a magnetorheological material was presented. The influence of the volume fraction of carbonyl iron particles (the share of the carbonyl iron particles varied from 1.5 to 33.0 vol. %.) on the mechanical properties of the material were investigated, in particular on the Young's modulus variation. Experimental tests were carried out for specimens made of pure PU 70/30 elastomer with iron particles. They induded uniaxial compression tests. In the farmer case, specimens were in a shape of a cylinder with a diameter of 20 mm and a height of 25-30 mm. The results of experimental tests carried out in order to determine the parameters necessary to build the numerical model were induded in the paper. In the paper, an algorithm developed for determining the parameters for modelling the structure was presented. A fragment of the structure, containing several particles of iron and some quantity of elastomer, corresponding to the assumed volume fractions, was subjected to numerical analysis.

Opis:
When evaluating or ordering alternatives concerning given multiple criteria, decision-makers often use aspiration and reservation levels for criteria, which allows them to define some reference alternatives that build a common framework for the evaluation. In this paper, new multiple criteria approach, called distances to aspiration reference points (DARP), is presented, which can be implemented in a specific evaluation or ranking problem when many different aspiration levels should be taken into consideration. One example of such problem is measuring sustainable development of countries or states within the Union. In DARP, to measure the performance of alternative (state), the notion of distances between alternative and individual or common aspiration reference points is used. To manage the problem of different reference points, a modified max-min normalisation technique is proposed. DARP application for measuring smart growth of the EU countries is conducted to demonstrate the effectiveness of the proposed method.

Opis:
The objective of this paper is to present the results of research carried out to develop a design method for Smart Cities systems. The method is based on the analysis of design cases of Smart Cities systems in cities, the selection of the city appropriate to the requirements for implementation and application. The Case Based Reasoning method was used to develop the proposed design methodology, along with mechanisms of the conversion of project processes and roles to Rational Unified Processes (RUP). The prerequisite for the proposed method is that the enterprise manager must be knowledgeable about high-level Smart Cities system architecture and the design framework applied. The authors, being themselves knowledgeable about architecture of this kind and about project environments which implement KPI models, propose a generic solution applicable to any environments and system architectures.

Opis:
To effectively transport materials through different means of transport, it is essential to have an optimized warehouse logistics first. Thanks to the Industry 4.0 platform, there are several ways to accomplish the delivery of materials from a warehouse through transport by road, rail or air. This paper deals with a primary warehouse problem, which is the fast and accurate search and selection of required items in the stock. For this issue, the use of smart glass technology and its implementation in the logistic processes of warehouses could help. In a particular way, an IRS (Integrated Rescue System) warehouse was selected as an example. The augmented reality (AR) type of glasses was selected. The introductory part of this paper deals with the current situation in the warehouse and logistic processes, where the problem of lack of qualified staff and material supply is prevalent, particularly during different crisis situations, such as pandemics or high employee turnovers. The use of smart glasses is one of the many possible problem-solving variants in this field. Further, a basic description of smart glasses, possible uses and sorting are presented in this paper. For the experiment, it was necessary to choose several different commercially available models of smart glasses. An evaluation was provided by the Simple comparative method, Saaty's method and Linear partial utility function method and the best options were identified. Also, there is an example of smart glasses application for picking a particular component in an IRS warehouse in the last part of this paper.

Opis:
Accurate network fault diagnosis in smart substations is key to strengthening grid security. To solve fault classification problems and enhance classification accuracy, we propose a hybrid optimization algorithm consisting of three parts: anti-noise processing (ANP), an improved separation interval method (ISIM), and a genetic algorithm-particle swarm optimization (GA-PSO) method. ANP cleans out the outliers and noise in the dataset. ISIM uses a support vector machine (SVM) architecture to optimize SVM kernel parameters. Finally, we propose the GA-PSO algorithm, which combines the advantages of both genetic and particle swarm optimization algorithms to optimize the penalty parameter. The experimental results show that our proposed hybrid optimization algorithm enhances the classification accuracy of smart substation network faults and shows stronger performance compared with existing methods.

Opis:
Sound localization tools are important in the environmental protection and the human searches. The article is one of the stages of the implementation of the concept of using aircraft to localize sound sources. The use of a fixed-wing aircraft instead of a multirotor would increase the total flight time, and expand the surveyed area. It is important to determine the most favourable positions of the receivers on the surface of the aircraft. The scattering effects of the sound waves coming from the ground source and aircraft engine on the acoustic field on the aircraft surface are not homogeneous. In the article the authors present the modelling of the scattering of the sound waves over the airplane surface with the usage of boundary element methods. After determining the effects from the sound source on earth and from the aircraft engine the conclusion was made, that the influence from the engine noise is greater than that from the ground source, and in order to localize the low amplitude signals, the aircraft need to glide. Considering only the effects of the ground source, the optimal areas for the microphones placement were determined.
