Abstract

In the opinion of Bogusław Wolniewicz (1927–2017), Wittgenstein in his Tractatus presented a new metaphysics – a modern ‘metaphysics of facts’, in opposition to the traditional ‘metaphysics of substance’ (Aristotle) or to the ‘metaphysics of things’ (Tadeusz Kotarbiński’s ‘reism’). The new metaphysics describes, just like the old ones did, the structure of the world. First, it refers to the world as a whole, seeing in it an actualization of one of numerous possible worlds. It also refers to the elementary unit of world-structure, which is an ‘atomic fact’ (an independent unit, though at the same time not the simplest one, since it involves further ‘simple objects’). Those concepts of ‘world’, ‘atom’ and ‘possible beings’ make the system of Tractatus ‘metaphysics’, comparable to the Aristotle’s metaphysics of ‘form’ and ‘matter’. In Tractatus, the Aristotelian ‘matter’ turns into ‘simple objects’, while ‘form’ becomes a form of ‘fact’. In this view, the world is conceived as a set of facts and equals a particular choice made from the universe of possible situations. But one element is missing in Wittgenstein’s system, namely, the ‘efficient cause’ responsible for the choice of facts (actualization of possibilities). Leibniz believed there was a ‘sufficient reason’ why a particular choice was made among possible situations and one possible world has become real. This ‘sufficient reason’ finally turned out to be God’s rational will. In Wolniewicz’s late philosophy however, the ‘efficient cause’ is only ‘fate’ or ‘chance’ (τύχη). Fate is therefore the mysterious deus absconditus of Wittgenstein’s metaphysics.

Abstract

The author paints a personal and often critical image of three cities — those, which he is the most familiar with and which are particularly dear and close to him. Despite being familiar with tens of the most renowned cities in the world, the author has selected fully familial examples, which he has had and continues to have personal ties. Throughout their histories, they have been subjected to dramatic events. In terms of spatial creation, they underwent — and continue to undergo-fluid, hybrid, ambivalent and often controversial transformation. They have also been treated implicitly, as subjectively-presented models of cities in general — as well as of their fate and evolution. The author considers the city to be — perhaps — the greatest expression of human culture and civilisation.

Abstract

The article presents research on the use of Monte-Carlo Tree Search (MCTS) methods to create an artificial player for the popular card game “The Lord of the Rings”. The game is characterized by complicated rules, multi-stage round construction, and a high level of randomness. The described study found that the best probability of a win is received for a strategy combining expert knowledge-based agents with MCTS agents at different decision stages. It is also beneficial to replace random playouts with playouts using expert knowledge. The results of the final experiments indicate that the relative effectiveness of the developed solution grows as the difficulty of the game increases.

Abstract

Złoże dolomitów Ujków Stary jest pozabilansowym fragmentem dawnego złoża rud cynku i ołowiu kopalni Bolesław. Opracowanie jego dokumentacji geologicznej z 2006 roku stworzyło nowe perspektywy pozyskania surowca skalnego ze skał dolomitycznych dolnego i środkowego wapienia muszlowego, występujących w serii złożowej. Skały te są wyraźnie zróżnicowane pod względem cech strukturalnych i teksturalnych oraz udziału składników mineralnych. W artykule przedstawiono charakterystykę tej zmienności na podstawie badań próbek skał pobranych z różnych części dwóch poziomów eksploatacyjnych złoża. Stwierdzono, że w złożu występują dolomity o strukturze mikrosparytowej i sparytowej (drobnokrystalicznej i średniokrystalicznej) oraz brekcje dolomityczne. Dowiedziono, że różnorodność petrograficzna skał, związana z ich genezą, ma istotny wpływ na zmienność ich podstawowych fizyczno-mechanicznych właściwości: gęstości objętościowej, nasiąkliwości i wytrzymałości na ściskanie. Ta zmienność petrograficzna skał decyduje także o niejednorodności jakościowej uzyskanych z nich kruszyw. Podstawą do wnioskowania w tym zakresie były wyniki badań odporności na ścieranie (wskaźnik mikro-Devala) i rozdrabnianie (wskaźnik Los Angeles) oraz ocena poziomu reaktywności alkalicznej kruszyw reprezentujących wybrane odmiany dolomitów oraz mieszaninę wszystkich wydzielonych odmian. Stwierdzono, że poszczególne partie kruszywa dolomitowego, pozyskiwane z różnych części złoża, mogą odpowiadać odmiennym kategoriom, określonym przez normy PN-EN. Wykazują one tym samym zróżnicowaną przydatność do stosowania ich między innymi w betonach, mieszankach bitumicznych stosowanych w powierzchniach przeznaczonych do ruchu oraz w niezwiązanych i związanych hydraulicznie materiałach używanych w obiektach budowlanych i budownictwie drogowym.

Abstract

Bogusław Wolniewicz presented his axiological system in four volumes of Filozofia i wartości (“Philosophy and Values”: 1993, 1998, 2003, 2016). For Wolniewicz, just as for his mentor Henryk Elzenberg, axiology is openly assertive and encompasses a painful confrontation of opposite moral beliefs. Wolniewicz’s vision of the reality is gloom, bitter, dramatic and deeply pessimistic. In history he detects unwelcome contributions of demonic powers (Manichaeism), he also believes that human moral character is genetically given and immutable (determinism), that some people are deprived of conscience (dualism), and that the tendency toward evil cannot be reformed (non-meliorism), human reason is not sufficient for a morally good action (voluntarism), while the so-called free will is no more than a manifestation of instincts (irrationalism). Everyone follows their pleasure (hedonism), but not everyone seeks pleasure in the same actions. In particular, some people take pleasure in cruel and destructive behaviour (demonism), while some others mind their own business (utilitarianism), and rare are those who devote themselves to higher values (perfectionism). Religion is a human invention and it emerges as a natural phenomenon in reaction to the fact of mortality. The institution of the Church should nevertheless be honored even by nonbelievers because it supports conservative values. In contemporary Western civilization a crisis can be observed between the conservative part of society (‘right-handed orientation’) and the liberal one (‘left-handed orientation’). Hateful emotions appear on both sides and are dangerous to Western unity. Conservative orientation is attached to the idea of fate, i.e. irrational power that occasionally turns human life into tragedy (fatalism). Wolniewicz’s vision is close to the theology of St. Augustine (original sin, predestination, radical dualism of good and evil) but without a consolation in hope for immortality.

Abstract

This article concludes a series of three articles. The first two, published in 2022, were divided into time periods; 1) until 1989, and 2) since the 1990s. The present one discusses the issue of the fate of police officers after September 1, 1939, and includes a summary and research postulates. The timelines used in the series are not accidental, of course, as they had a significant impact on the way historiography devoted to public security organs was conducted in the interwar period. The literature that deals with pre‑war police is relatively rich in terms of quantity. However, it is worth examining it more carefully as several works raise a number of questions and doubts. Next to very good ones there are some that should not have been published. If we take a closer look at the style of narration in particular publications, we will notice that the authors in the vast majority limit themselves to describing and reporting facts, avoiding factual analysis. Many of the publications deviate from scientific standards, focusing their attention exclusively on creat-ing the preferred image of the public security organisation in a given period of time. Unfortu-nately, this is noticeable not only before 1989, but also later, when the negative image of the pre‑war police was replaced by its excessive glorification or even mythologisation. Despite the fact that more and more issues are raised and some of them are further developed, we still cannot consider the state of research that I am interested in as being satisfactory. The following issues still need to be highlighted and thoroughly investigated: 1) police biography; 2) issues of formation, socialisation and mentality; 3) the state of morale of the police corps; 4) participation in the Polish‑Soviet war; 5) participation in ensuring the internal security of the state; 6) police‑society relations, including the creation of the image of the police in culture texts; 7) police participation in the protection of state dignitaries; 8) international police co-operation; 9) the history of the police in the individual provinces; 10) women’s police service; 11) the functioning of police associations and cultural and educational activities; 12) war pre-parations; 13) the fate of police officers after September 1, 1939.

Abstract

This study proposes the LoRa-Based Mesh Sensor Network without relying on LoRaWAN connection sending the communication data in the form of Star-to-Star, it can be sends the data in the form of peer-to-peer without the gateway. In the case that a longer distance is needed, the system is connected by a means of multi-hop presenting the hardware and software model through the use of low voltage power. Then, the testing is done using point to point and the received signal is measured by a gauge and compared with the model in accordance with the theoretical principle.

Abstract

Maritime Autonomous Surface Ships (MASS) perfectly fit into the future vision of merchant fleet. MASS autonomous navigation system combines automatic trajectory tracking and supervisor safe trajectory generation subsystems. Automatic trajectory tracking method, using line-of-sight (LOS) reference course generation algorithm, is combined with model predictive control (MPC). Algorithm for MASS trajectory tracking, including cooperation with the dynamic system of safe trajectory generation is described. It allows for better ship control with steady state cross-track error limitation to the ship hull breadth and limited overshoot after turns. In real MASS ships path is defined as set of straight line segments, so transition between trajectory sections when passing waypoint is unavoidable. In the proposed control algorithm LOS trajectory reference course is mapped to the rotational speed reference value, which is dynamically constrained in MPC controller due to dynamically changing reference trajectory in real MASS system. Also maneuver path advance dependent on the path tangential angle difference, to ensure trajectory tracking for turns from 0 to 90 degrees, without overshoot is used. All results were obtained with the use of training ship in real–time conditions.

Abstract

A key role in the development of smart Internet of Things (IoT) solutions is played by wireless communication technologies, especially LPWAN (Low-Power Wide-Area Network), which are becoming increasingly popular due to their advantages: long range, low power consumption and the ability to connect multiple edge devices. However, in addition to the advantages of communication and low power consumption, the security of transmitted data is also important. End devices very often have a small amount of memory, which makes it impossible to implement advanced cryptographic algorithms on them. The article analyzes the advantages and disadvantages of solutions based on LPWAN communication and reviews platforms for IoT device communication in the LoRaWAN (LoRa Wide Area Network) standard in terms of configuration complexity. It describes how to configure an experimental LPWAN system being built at the Department of Computer Science and Telecommunications at Poznan University of Technology for research related to smart buildings.

Abstract

The basic tests that allow the mechanical properties of grained material to be evaluated are tests of an aggregate’s resistance to crushing - the Los Angeles coefficient, and resistance to abrasion - the micro-Deval coefficient. These parameters primarily depend on the physical and mechanical properties of the raw material from which they are produced. The available literature widely describes the relationship between these parameters and bulk density, porosity, ultrasonic wave velocity, compression strength, tensile strength and point strength. This paper presents the relationship between the mechanical properties of aggregates and their geometrical properties. The analysis was carried out for the relationship between the Los Angeles and micro- Deval coefficients and the flatness and shape indices. As a result of the conducted considerations, the influence of the aggregate assortment on the analysed coefficients was also noted. All of the tests were carried out for aggregates (arch stones and mixtures) produced from sandstones from the Magura, Cergo and Krosno layers.

Abstract

It has been acknowledged that two important rock aggregate properties are the Los Angeles abrasion value (LAAV) and magnesium sulphate soundness (M wl). However, the determination of these properties is relatively challenging due to special sampling requirements and tedious testing procedures. In this study, detailed laboratory studies were carried out to predict the LAAV and M wl for 25 different rock types located in NW Turkey. For this purpose, mineralogical, physical, mechanical, and aggregate properties were determined for each rock type. Strong predictive models were established based on gene expression programming (GEP) and artificial neural network (ANN) methodologies. The performance of the proposed models was evaluated using several statistical indicators, and the statistical analysis results demonstrated that the ANN-based proposed models with the correlation of determination (R2) value greater than 0.98 outperformed the other predictive models established in this study. Hence, the ANN-based predictive models can reliably be used to predict the LAAV and M wl for the investigated rock types. In addition, the suitability of the investigated rock types for use in bituminous paving mixtures was also evaluated based on the ASTM D692/D692M standard. Accordingly, most of the investigated rock types can be used in bituminous paving mixtures. In conclusion, it can be claimed that the proposed predictive models with their explicit mathematical formulations are believed to save time and provide practical knowledge for evaluating the suitability of the rock aggregates in pavement engineering design studies in NW Turkey.

Abstract

This article provides a comparison of various wireless data transmission protocols, such as Wireless M-Bus, Lo- RaWAN, Sigfox, NB-IoT and a newly developed proprietary protocol, studying their performance in the application of batterypowered residential water meters. Key aspects of the comparison include energy consumption, which is analyzed through comparing unitary amount of charge required to conduct a single, bidirectional data transaction between the meter and base station, and maximum coupling loss which effectively defines the range and coverage in the system. For completeness, the study includes also a brief cost analysis and ends with a conclusion, stating when each of the particular standards should be favored.

Abstract

In his book Mortal Questions (1979) Thomas Nagel discusses four practical moral issues: (1) fear of death, (2) the absurdity of human life, (3) sexual perversion and (4) military massacre. His primary concern is neither to justify moral opprobrium nor to find an appropriate punishment for the culprits. Instead, he wants to clarify motives of those individuals who are not afraid of death, who can deal resolutely with the pointlessness of human life, who are not deeply dismayed by the crudity of some forms of sexual behavior or who refuse to justify whatever forms of military atrocities with higher purposes. He reviews various cases of excessive or deficient moral sensitivity and offers specific, case‑oriented advice on how to deal with them. Nagel favors self‑persuasion in cases of fear of death and argues that the sense of absurd is not much different from skepticism. He proposes to draw a line between private and public aspects of sexual behavior and supports dual evaluation of military activities by distinguishing between the moral value of an act and the moral value of the motives of the actor. He condones no atrocities. These arguments do not add up to constitute a form of moral relativism but, instead, seem to restore intellectual respectability of casuistry.
