Good practices in the creation of the Commune Revitalization Program – cooperation between the University of Adam Mickiewicz and the City of Kalisz, The entry of the Revitalization Act on November 18, 2015 enabled municipalities to efficiently plan and conduct the process of moving degraded areas out of the crisis. The Act introduced key regulations affecting the programming of revitalization in Poland. One of the most important instruments is the Municipal Revitalization Program. In order to be able to fully use the potential of this document, we should look for solutions that allow creating the most comprehensive solutions. One of the examples of such activities is cooperation between the university and the local government. Thanks to this combination of practical knowledge of officials with theoretical knowledge of academic experts, we can say that it is a project unique in the country. It is also unique due to the fact that spatial economy students who actively participated in the document creation process were included in the work. The aim of the work is to present the course of the cooperation process of the University of Adam Mickiewicz with the Office during the preparation of the Municipal Revitalization Program for the city of Kalisz and showing the role that the students included in the project played in this project

Experiences of subregional cities in programming of urban renewal. The aim of the article is to analyze and evaluate the experience of selected subregional cities in revitalization programming. At the beginning, the strategic policy of the state towards subregional centers was defined. The guidelines from the National Spatial Development Concept, the National Urban Policy and the Strategy for Responsible Development were pointed out. Then, examine in detail the activities carried out so far in 4 cities, which as a result of the administrative reform in 1999 lost the status of the provincial city, i.e. in Ciechanów, Legnica, Piła and Przemyśl. Current documents have been characterized, in particular, the specificity of areas covered by revitalization has been described. Next, the leading directions of transformations of these areas were presented, resulting from the adopted revitalization policy. This allowed for the formulation of certain generalizations about the specificity of the process of renewal of degraded areas in subregional centers in Poland.

In the paper, the simulation PROP5 program is used to predict the sound level in proximity of a road with defined surroundings. The simulation involves road geometry (number of lanes and their positions) and traffic structure (vehicle flow rates and their average speeds), with equivalent omnidirectional point sources representing vehicles. In Part I of the paper, the agreement between measurement and simulation results is tested to verify the accuracy degree of the applied models of a road, as a noise source and propagation throughout surrounding space. In Part II, using the pre-tested simulation program, the possibility of acoustic climate improvement has been analyzed.

n the paper, the simulation PROP5 program with the road model defined as a noise source and road surroundings model, is used to predict the efficiency of noise protecting means for the chosen building. The appropriate models of verified accuracy have been chosen by comparison of the simulation results with field measurements (Walerian et al., 2010). Here, using the pre-tested simulation program, the possibility of acoustic climate improvement has been analyzed in the ranges of practical variations of the input parameters. The road parameters: its geometry (number of lanes and their positions) and traffic structure over lanes (vehicle flow rates and their average speeds) have been taken under consideration as changeable parameters, that could be corrected to obtain acoustical climate improvement. Moreover, an acoustical screen designing has been considered. The screen efficiency has been evaluated under conditions defined by the input parameters of the road and its surroundings.

The research is devoted to the organization of the energy policy objectives implementation

through programs. A country’s energy policy can be monitored in many ways. The article proposes

to consider the implementation of energy policy objectives with the budget programs maintenance

on the example of Ukraine. Budget programs make it possible to trace the dynamics of changes in

the aim and directions of the authorities’ energy policy, implemented for budgetary funds. With the

budget programs since 2002 in Ukraine, it was possible to trace the increase in spending on the coal

industry, highlight the funding forced of negative consequences in the energy sector and separate

the steps to develop an energy strategy. Changes in the totality of energy policy budget programs

are shown, their contents are considered. The decrease in the budget programs number associated

both with the enlargement of their aim and with the withdrawal expenses for reconstruction and

social protection of those affected by the previous energy activities from the budget funding. To

assess budget programs planning and implementation uniformity the author’s integrated indicator is

proposed. It takes the funding level and the quality indicator implementation on assignment directions

into account. The calculation of the indicator showed that the expenditures for the general

management of the energy policy and for scientific development are planned in the programs more

evenly than the expenses for the energy strategy implementation.

Bilevel programming problem is a non-convex two stage decision making process in which the constraint region of upper level is determined by the lower level problem. In this paper, a multi-objective indefinite quadratic bilevel programming problem (MOIQBP) is presented. The defined problem (MOIQBP) has multi-objective functions at both the levels. The followers are independent at the lower level. A fuzzy goal programming methodology is employed which minimizes the sum of the negative deviational variables of both the levels to obtain highest membership value of each of the fuzzy goal. The membership function for the objective functions at each level is defined. As these membership functions are quadratic they are linearized by Taylor series approximation. The membership function for the decision variables at both levels is also determined. The individual optimal solution of objective functions at each level is used for formulating an integrated pay-off matrix. The aspiration levels for the decision makers are ascertained from this matrix. An algorithm is developed to obtain a compromise optimal solution for (MOIQBP). A numerical example is exhibited to evince the algorithm. The computing software LINGO 17.0 has been used for solving this problem.

In the second part of the article, the history of standardization programmes concerning the names of physiographic objects is discussed. The basis of the standardization programme currently followed by the Commission on Names of Localities and Physiographic Objects is described. The paper also presents the criteria of linguistic correctness adopted by the previous standardization commissions as well as by the present one. Issues of linguistic correctness of geographical names with dialectal properties and of names borrowed from minority languages are discussed. Attention is paid to some structural discrepancies in the approaches to the issue of correctness taken by the Commission on Names of Localities and Physiographic Objects and by local authorities.

Electric arc is a complex phenomenon occurring during the current interruption process in the power system. Therefore performing digital simulations is often necessary to analyse transient conditions in power system during switching operations. This paper deals with the electric arc modelling and its implementation in simulation software for transient analyses during switching conditions in power system. Cassie, Cassie-Mayr as well as Schwarz-Avdonin equations describing the behaviour of the electric arc during the current interruption process have been implemented in EMTP-ATP simulation software and presented in this paper. The models developed have been used for transient simulations to analyse impact of the particular model and its parameters on Transient Recovery Voltage in different switching scenarios: during shunt reactor switching-off as well as during capacitor bank current switching-off. The selected simulation cases represent typical practical scenarios for inductive and capacitive currents breaking, respectively.

This article contains information concerning of the analysis the possibility of defining refinery qualities of the slag based thermophysical and thermodynamical data. The paper presents a model of slag refining processes and a method of determining the reduction capability of slag solutions. Slag was analysed with the use of the DTA methods for the brass melting conductions. The study of computer program including the satisfactory number of data there are used in to the design a modern device rotating head used for gas-slag refining. It was achieved that the refining gas and fluxes were distributed ever by the rotating head. High effectiveness of the gas-slag refining processes was proved for the brass.

The article describes the optimization of the melting brass. Brasses, as one of the most popular alloys of copper, deserve special attention

in the context of the processes of melting, which in turn would provide not only products of better quality, but also reduce the cost of their

production or refining. For this purpose, several studies carried out deriatographic (DTA) and thermogravimetric (TG) using

derivatograph. The results were confronted with the program SLAG - PROP used to evaluate the physicochemical properties of the

coatings extraction. Based on the survey and analysis of the program can identify the most favorable physico - chemical properties, which

should be carried out treatments. This allows for slag mixtures referred configurations oxide matrix containing specific stimulators of the

reaction. Conducted empirical studies indicate a convergence of the areas proposed by the application. It should also be noted that the

program also indicates additional areas in which to carry out these processes would get even better, to optimize the melting process, the

results.

The revitalization of brownfi elds and post-industrial facilities is a long-term and multistage process. In the first stage of revitalization, it is important to assess the material, emotional and utilitarian value of the preserved cultural heritage. On the example of a revitalization project that has been ongoing since 1996, the former areas of the Gdańsk Shipyard, where the remains of the Imperial Shipyard and Schichau Shipyard are located, the process of formulating the value of the preserved cultural material heritage has been presented. The impact of this process on the subsequent stages of the revitalization of the Young City in Gdańsk was also presented. Gdańsk Shipyard is the cradle of Solidarity, so the emotional value associated with the events accompanying the creation of the Solidarity movement was considered to be the dominant one. Only two objects were entered in the register of monuments; BHP Hall and Solidarity Square (Plac Solidarności). When the Local Development Plan has been passed many investments have begun by various investors without comprehensive integrated activities. The demolition of the preserved halls and the dismantling of shipyard equipment began. This caused that in 2015 the uniqueness of the survived post-industrial complex, qualifying it for inclusion in the World Heritage list, was appreciated. In 2018, the Provincial Pomeranian Monument’s Conservator began the procedure of entry of the preserved objects to the register of monuments. This resulted in the suspension of all investments that commenced legally in the area covered by the proceedings. Lack of proper assessment of the cultural value of material heritage at the stage of preparing the revitalization process led to the loss of part of this heritage and caused increase of the investment activities risk in this area.

The article is part of the trend of research on revitalization. It presents the methodology of the process of diagnosis and separation of the degraded area from the revitalized one, for the needs of the Local Revitalization Program. The article describes the stages of the process, the examples of used measures, as well as problems appearing at diff erent stages of the study. The methodology is presented on the example of the small town of Wojkowice from the Śląskie Province.

Poland’s National Vaccination Program is an essential element in the strategy of prevention of infectious diseases and their complications, here considered with a particular focus on combination vaccines and the need for the Program’s further expansion.

The smart household connected to the energy dispatch arises to overcome the environmental crisis, encourages the penetration of renewable energies and promotes consumer respond to intraday market prices. Aquaponic production results from the combination of fish farming and hydroponics (cultivating plants using fish waste as nutrients). The prototype was built based on the rule of the 3 Rs: reduce, reuse and recycle. The crop reduces the consumption of water and energy, reuses water in a recirculation process, which is filtered by: 1) gravity, 2) biofilters and 3) porosity. Recycling is expanded to plastic containers and food containers of polystyrene. The aquaponic production system is decorative, completely organic (without chemicals), promotes the growth of green areas for comfortable homes and allows the consumption of healthy food, as well as energy planning to save energy. The system is done with a digital level control connected to a water pump and an oxygen pump. A novel method allows the aggregator to optimize the recirculation programming of the aquaponic system for periods of 24 hours. The method maximizes the economic benefits with the help of an energy balance between hours.
