The article deals with the creation of a program for stopping an autonomous robotic vehicle Robotino® 4. generation at a defined distance from an obstacle. One of the nine infrared distance sensors located on the frame of the robotic vehicle in the front part of the frame is used for this application task. The infrared distance sensor characteristic is created from the measured experimental data, which is then linearized in the given section. The main aim of the experiment is to find such an equation of a line that corresponds to the stopping of a robotic vehicle with a given accuracy from an obstacle. The determined equation of the line is applied to the resulting program for autonomous control of the robotic vehicle. This issue is one of the many tasks performed by AGV in the industry. The introduction of AGVs into the industry is one of the many possibilities within Industry 4.0.

"Neben der Industrie hat die Digitalisierung auch die Natur ergriffen. Die Tatsache, dass Tausende von Tieren mit GPS-Sendern aus- gerüstet und überwacht werden, erlaubt, analog zur Industrie 4.0 auch von einer Natur 4.0 zu sprechen. Dieses Internet der Tiere verändert den Begriff, den der Mensch von der Natur hat. Er transformiert die Wahrnehmung vor allem der Natur als etwas fundamental An- deren. Neben den vielen kulturellen Problematisierungen, die das Internet der Tiere mit sich bringt, lassen sich aber auch die Umrisse einer neuen, ganz und gar nicht esoterischen planetarisch-post-digitalen Kultur aufzeigen, die die conditio humana verändert. In addition to industry, digitalization has also taken hold of nature. The fact that thousands of animals are provided and monitored with GPS transmitters allows to speak of nature 4.0 by way of analogy to industry 4.0. This internet of animals changes our idea of nature. Most of all, it transforms the perception of nature as something fundamentally other. Beside the many cultural problems that the internet of animals implies, it can also outline a new, not at all esoteric planetary post-digital culture that is about to change the human condition. "

The article suggests an approach to revelation anthroponymic markers of the integrated national cultural space, the creation and the preservation of which acquired especial significance in the 21st century due to the rapid globalization. Obviously, that proper names, which carry multifaceted historic and cultural information concerning people's life, constitute the major part of Russian cultural basis. Thus, the question arises, how to find these proper names in such a vocabulary diversity. Correspondingly, the exploration of proper names and theirs value on regional level using objective experimental data, can be considered as a “filtr” for the detection of such proper names. The experience of conducting such explorations of Smolensk's onomastic material is described in this article.

The late Middle Ages witnessed the creation of numerous fencing books, mostly in Germany, illustrating the many different techniques, weapons, styles, strategies, and the movements, as Patrick Leiske discussed only recently in his Höfisches Spiel und tödlicher Ernst (2018; see my review here in vol. 32). Some of the true masters and teachers of this sport and fighting technique were Johannes Liechtenauer, Peter von Danzig, Sigmund Ringeck, and Hans Talhoffer, whom Leiske also discusses in a separate chapter.

The solubilities of cesium dianilinetetraisothiocyanatochromate(III) in water as well as in aqueous methanol, isopropyl alcohol, tert-butyl alcohol and acetonitrile were measured as a function of temperature and solvent composition. The Gibbs energies, enthalpies and entropies of transfer of the salt from water to the given solvents have been evaluated from experimental data. The contribution of [Cr(C6H5NH2)2(NCS)4]- ion to the Gibbs energy of transfer of the investigated salt has been calculated using the tetraphenylarsonium tetraphenylborate (TATB) reference electrolyte assumption.

AbstractReactivity, or the phenomenon by which subjects tend to modify their behavior in virtue of their being studied upon, is often cited as one of the most important difficulties involved in social scientific experiments, and yet, there is to date a persistent conceptual muddle when dealing with the many dimensions of reactivity. This paper offers a conceptual framework for reactivity that draws on an interventionist approach to causality. The framework allows us to offer an unambiguous definition of reactivity and distinguishes it from placebo effects. Further, it allows us to distinguish between benign and malignant forms of the phenomenon, depending on whether reactivity constitutes a danger to the validity of the causal inferences drawn from experimental data.

The method of increments is a wavefunction-based ab initio correlation method for solids, which explicitly calculates the many-body wavefunction of the system. After a Hartree-Fock treatment of the infinite system the correlation energy of the solid is expanded in terms of localised orbitals or of a group of localised orbitals. The method of increments has been applied to a great variety of materials with a band gap, but in this paper the extension to metals is described. The application to solid mercury is presented, where we achieve very good agreement of the calculated ground-state properties with the experimental data.

This article sets out to present a new imagery for capturing the power and potential of Olympism in attempting to educate the next generation of sport consumers and decision makers. It is hoped that the new imagery can make a contribution on how to moderate and regulate the rampant commodification of sport. This new imagery begins with the need for physical educators to open their minds and instigate a critical orientation to thinking about sport and Olympic matters. It is argued that doing this might help in the creation of new possibilities and visions for Olympism and sport and allow us to confront some of the disagreeable contemporary concerns in sport that scholars have identified. The new imagery for Olympism is based on the development of a critical pedagogy that draws on the works of Apple, Freire and Kincheloe, and is re-contextualised for school physical education and sports programmes. It is concluded that decisions, behaviours and actions that are made at present actually propagate many of the policies that will be made tomorrow. It is argued that a critical pedagogy for Olympism is needed to address the many current disagreeable aspects of sport.

During the past few years an extensive amount of experimental data on split flaps has been made available to the aircraft industry, through the publications of aeronautical research laboratories, both in this country and abroad. In general, each publication deals with one particular aspect of the problem, and when the effect of wing flaps on the performance of an aircraft is being estimated a certain amount of difficulty may be experienced in deciding which of the many reports available gives results most readily applicable to the case being considered ; and what allowances, if any, should be made for wing taper, flap cut-out, fuselage, etc.In this report the available data has been analysed with a view to answering these questions, and presented in such a form that it may be readily applied to determine the most probable change in the aerodynamic characteristics of a wing that may be expected from the use of this type of flap.From the appendix an estimate of the accuracy of the method can be obtained, as a comparison with full-scale data is given for lift and drag, and for the other flap characteristics the original curves have been reproduced.

RESUMOEste artigo tem por objeto a Teoria dos Direitos Humanos em Michel Villey. Seu objetivo é apresentar uma contestação à alegação de Michel Villey de que os direitos humanos não podem ser considerados Direito. Para tanto, realiza uma apresentação da Teoria dos Direitos Humanos em Michel Villey, passando pela criação dos direitos humanos em Thomas Hobbes, a inversão de objetivos dos direitos humanos em John Locke e a expansão dos direitos humanos em Christian Wolff. Em seguida passa a apresentar a crítica de Michel Villey aos direitos humanos e as falhas deste autor ao realizar suas acusações, haja vista a possibilidade de solução das contradições (colisões) entre os direitos humanos, além de que não se pode confundir o critério de validade da norma com sua eficácia. O trabalho conclui pela juridicidade dos direitos humanos ao demonstrar que a suposta contradição não seria razão para retirar esta qualidade.PALAVRAS-CHAVEFilosofia do Direito. Direitos Humanos. Michel Villey. ABSTRACTThe present work deals with the General Theory of Human Rights in Michel Villey. Its purpose is to present a challenge to Michel Villeys’ claim that human rights are not legal norms. To do so, the text presents the General Theory of Human Rights in Michel Villey, including the creation of human rights by Thomas Hobbes, the changing perspective attributed to John Locke and the numerical expansion of human rights attributed to Christian Wolff. The text then presents Michel Villeys’ critics of human rights and the problems with those critics; specifically, that the given conflicts between norms aren’t sufficient to declare that they aren’t legal norms, other than that, the text points that in his critics Michel Villey confuses the concepts of validity of the norm with its effectiveness. The work concludes that human rights are legal norms and its supposed intrinsic contradiction is not sufficient to withdraw this quality.KEYWORDSPhilosophy of Law. Human Rights. Michel Villey.

Despite the recent academic attention community cookbooks have finally been granted, little has been said about compiled family cookbooks. Even works such as Janet Theophano's Eat My Words, Andrea Eidinger’s "Gefilte Fish and Roast Duck with Orange Slices": A Treasure for My Daughter and the Creation of a Jewish Cultural Orthodoxy in Postwar Montreal” and Marie Drews’ examination of In Memory's Kitchen, are about works by, and for, an entire community rather than for family. Furthermore, though gender critics have long documented the imbalance of food-related work in the home by showing that women have always been the primary food makers, one cannot deny that the makeup of modern families has changed and that men and children are becoming more active in the kitchen. Drawing on past and current literature to analyse a family cookbook I made and gave to my cousin for her wedding, this essay draws academic attention to family cookbooks and family food practices. While the cookbook I analyse is predominantly feminine, the many male and child voices included in this collection, voices that are usually excluded from such works, prove that, when given a chance, these often silenced groups can, and do, impact a family's food habits.
