A new version of J2TADD - a translator from Java to automatons- is described, which adds support for a translation of Markov processes with non-dcterministic players, that can form coalitions, which in turn strive for different aims. In order to ease the definition of a probabilistic game using a plain Java application, several new constructs, and also a special library, are supported within the input language.
Ranges on variables or on expressions can be defined, what helps in checking the self-consistency of a model, and can also make the solving of the model faster.
The article discusses the point of interconnection between historical policy and international human rights law standards on the example of a so-called decommunisation Act enacted in Poland in 2016 that reduces retirement pensions and other benefits to individuals who were employed or in service in selected state formations and institutions in 1944-1990, amending the Act adopted in 2009. The Act of 16 December 2016 is analyzed in the light of the standards of the European Convention on Human Rights (ECHR), including relevant standards on coming to terms with the past as an element of transitional justice. The examination concludes that there is a discrepancy between the rationale for adopting this legislation in Poland, namely to reckon with the communist past and as such increase social trust in state institutions, and the legal solutions contained in the 2016 Act.
Iterative Learning Control (ILC) is a well-known method for control of systems performing repetitive jobs with high precision. This paper presents Constrained Output ILC (COILC) for non-linear state space constrained systems. In the existing literature there is no general solution for applying ILC to such systems. This novel method is based on the Bounded Error Algorithm (BEA) and resolves the transient growth error problem, which is a major obstacle in applying ILC to non-linear systems. Another advantage of COILC is that this method can be applied to constrained output systems. Unlike other ILC methods the COILC method employs an algorithm that stops the iteration before the occurrence of a violation in any of the state space constraints. This way COILC resolves both the hard constraints in the non-linear state space and the transient growth problem. The convergence of the proposed numerical procedure is proved in this paper. The performance of the method is evaluated through a computer simulation and the obtained results are compared to the BEA method for controlling non-linear systems. The numerical experiments demonstrate that COILC is more computationally effective and provides better overall performance. The robustness and convergence of the method make it suitable for solving constrained state space problems of non-linear systems in robotics.
The present study aimed to test how common workaholism is and which groups are most targeted in the workplace among Jordanian employees. Additionally, the roles of positive and negative perfectionism in workaholism were investigated. The sample consisted of 686 employees. All of them completed the study instruments. The results showed that the mean of workaholism was around the mean of the cut -off. Additionally, multivariate tests showed that the results of post hoc differences for positive perfectionism were in favor of males, subordinates, those with a bachelor’s degree, those with less than 5 years of experience, and those aged less than 30 years. Furthermore, the differences for negative perfectionism were in favor of those with a bachelor’s degree and subordinates. For workaholism, the differences were in favor of subordinates, public sector employees, married persons, and those with a diploma degree. Finally, the results of hierarchical regression analysis found that positive and negative perfectionism and some demographic variables predicted 12.9% of the variability in workaholism, and the typical hierarchical regression model included positive and negative perfectionism without other demographic variables.
This paper analyses the use of Polish achievements with durative expressions of godzinę (in an hour) and przez godzinę (for an hour) – types, their use in the progressive and finally a possible relationship between this use and the terminative recategorisation of imperfective achievements. In the analysis we have accounted for a number of linguistic and contextual factors that influence the possibility of the progressive use of achievements. This has allowed us to propose several subclasses of achievements that may undergo recategorisation under specific conditions set in the concluding section.
The present paper focuses on the changing interpretations of the English gerund. Since no method can accurately and uniformly account for the meanings of all instances of existing -ing forms, previous studies have offered approximate characterizations based on small samples. This study looks at the numbers of -ing derivations denoting institutionalized activities, on the assumption that these represent non-eventive readings. The derivations in question are arranged chronologically in terms of their time of coinage to compare changing productivity levels of this process relative to -ry derivations. This count shows that -ing suffi xations outnumber other nominalization processes and this trend has increased in the last two centuries.
Turbine stages can be divided into two types: impulse stages and reaction stages. The advantages of one type over the second one are generally known based on the basic physics of turbine stage. In this paper these differences between mentioned two types of turbines were indicated on the example of single stage turbines dedicated to work in organic Rankine cycle (ORC) power systems. The turbines for two ORC cases were analysed: the plant generating up to 30 kW and up to 300 kW of net electric power, respectively. Mentioned ORC systems operate with different working fluids: DMC (dimethyl carbonate) for the 30 kW power plant and MM (hexamethyldisiloxane) for the 300 kW power plant. The turbines were compared according to three major issues: thermodynamic and aerodynamic performance, mechanical and manufacturing aspects. The analysis was performed by means of the 0D turbomachinery theory and 3D computational aerodynamic calculations. As a result of this analysis, the paper indicates conclusions which type of turbine is a recommended choice to use in ORC systems taking into account the features of these systems.

In order to meet the application requirements of high-power mobile inductively-coupled power transfer (ICPT) equipment, the structure of the dual transmitter and pickup can be used to improve the transmission power of the ICPT system. However, this structure cannot easily describe the change of the mutual inductance parameter in the moving state, making the mathematical model difficult to establish. The change of load parameters during the movement will affect the current and voltage at the transmitter and pickup coils. Aiming at these problems, this paper proposes a dual transmitter and pickup ICPT system based on inductor-capacitor-inductor (LCL) compensation network, and analyzes its power trans- mission efficiency. By setting the shape and size of the coil, the influence of the change of the mutual inductance parameters on the system efficiency during the movement is reduced. The changes of the mutual inductance parameters of the ICPT system under the moving state are simulated by changing the coupling coefficient in the PSpice software. The results show that the structure of the ICPT system used in this paper can improve the output power and reduce the influence of the system when the load changes.
The historic municipal park located in Zduńska Wola is covered in the central and northern part by conservator protection through an entry in the register of monuments and on the basis of an entry in the local spatial development plan. In terms of nature, the area has significant values due to old trees and the water system, which consists of two ponds fed by the Pichna River. As part of the preparatory work for the revalorization of the park, several studies and analyses were carried out, including assessment of the sanitary state of waters of Pichna River that supplies reservoirs. Degree of the river pollution made it impossible to restore the water system, the most important element of the park, while further supplying the ponds with river water. In order to ensure a satisfactory degree of purity and transparency of water in ponds, a decision was made to apply complex and modern technological solutions enabling the renovation of the water system. Project documentation was developed in 2015. After two years, they began to implement the project. Banks of both ponds were formed more gently, and the basins were deepened. Selection of vegetation around the reservoir and in the reservoir itself was based on the principle of biocenotic assumptions. The designed system is equipped with a circulation pump, skimmers, bottom drains, mechanical-mineral filter, swamp filter. This was to ensure adequate purification of water in ponds, based on natural processes, stimulated by the use of new, pro-ecological technologies.
