DIGITIZATION OF THE HAKKA ANCESTOR WORSHIP CEREMONY

«Мировая церемония предков хакка» - одна из самых влиятельных церемоний поклонения предкам в Китае. В 2011 году это мероприятие было включено в Национальный список нематериального культурного наследия. Благодаря слиянию и сосуществованию нескольких моделей взаимодействия в «церемонии поклонения предкам» и точному пониманию намерений мультимодального взаимодействия синхронизировано представление многоканального восприятия (визуального, звукового и сенсорного). На основе Node.js и Three.js технологий авторами была реализована цифровая система для «церемонии поклонения предкам». Цифровая модель представляет действия в двух залах: Хуайцзу, где можно выразить свои чувства памяти и помолиться за свои семьи, и Юйпин, где можно произвести интерактивные операции, такие как подношение свечей, подношение благовоний и т.п. Тесты показывают, что в системе достигается баланс между производительностью и удобством для пользователя, что дает реальное решение для оцифровки нематериального культурного наследия ритуального типа. Цифровой контент церемонии не ограничен во времени и пространстве, не требует использования сторонних плагинов и имеет быструю доступность, что может способствовать быстрому распространению и развитию «Церемонии предков мира хакка». The Hakka World Ancestor Ceremony is one of the most influential ancestor worship ceremonies in China. In 2011, this event was included in the National List of Intangible Cultural Heritage. Due to the fusion and coexistence of several interaction models in the "ancestor worship ceremony" and an accurate understanding of the intentions of multimodal interaction, the representation of multi-channel perception (visual, sound and sensory) is synchronized. Based on Node.js and Three.js technologies, the authors implemented a digital system for the "ancestor worship ceremony". The digital model represents actions in two halls: Huaizu, where you can express your feelings of memory and pray for your families, and Yuping, where you can perform interactive operations, such as offering candles, offering incense, etc. Tests show that the system achieves a balance between performance and user-friendliness, which provides a real solution for digitizing intangible cultural heritage of the "ritual" type. The digital content of the ceremony is not limited in time and space, does not require the use of third-party plug-ins and has rapid availability, which can contribute to the rapid spread and development of the "Ceremony of the Ancestors of the Hakka World".

Interval Version of the Operational Calculation Method for Solving Ordinary Differential Equations

This article discusses the interval variant of solving ordinary differential equations with given initial conditions, i.e. the Cauchy problem, by the method of operational calculus. This is where the interval version of the operational calculus is motivated and built. As a result, on the basis of the proved theorem in this article, an analytic interval set of solutions is obtained that is guaranteed to contain a real solution to the problem.

How does historical faith complement Immanuel Kant’s philosophy of religion?

In modern interpretations of Kant’s philosophy of religion, a shift away from exclusionary moral reductionism occurs. Consequently, at least since the 1970s, historical faith has been appreciated as a necessary and desirable element of Kant’s philosophy of religion. One of the reasons prompting Kant to include historical faith in his system of the philosophy of religion is what commentators on Kant’s philosophy call the ‘moral gap’. For there is a disproportion between the limited competence of man as a natural being and moral goals that seem unattainable. For the believer, the content of historical faith offers a real solution to the disproportion between his limitations as a natural being and the goals set for him by practical reason. For the believer, the ‘moral gap’ is not just a theoretical problem, but an existential challenge whose solution does not lie within his own limited competence. In this article, I consider whether historical faith can also provide a theoretical supplement to the picture of one’s own life. If so, then the content of historical faith may also prove important for the non-believer.

Antimonopolism as a Symptom of American Political Dysfunction

Contemporary American interest in using antitrust law to address wealth inequality is a symptom of American political dysfunction rather than a reflection of any intellectual advance regarding the sources of inequality. Indeed, both the original American progressives of a century ago, as well as Thomas Piketty, whose work sparked contemporary intellectual interest in inequality, agree that inequality’s source is scarcity, rather than monopoly, and so will persist even in perfectly competitive markets. The only real solution is taxation, not a potentially destructive campaign of breakup. There are two cause of contemporary American antimonopolism. The first is American anti-statism, which has closed off tax policy as a viable political solution to inequality, forcing scholars and activists to seek a second- or third-best workaround in antitrust policy. The second is the American press, which is actively promoting antimonopolism as a way of fighting back against Google and Facebook, two companies that have badly outcompeted the press for advertising dollars in recent years. Given these idiosyncratic roots of contemporary American antimonopolism, other jurisdictions seeking to address inequality may have little to gain from following the American example, particularly if taxation remains a viable policy option for them.

Analyzing the Dual Space of the Saturated Ideal of a Regular Set and the Local Multiplicities of its Zeros

In this paper, we are concerned with the problem of counting the multiplicities of a zero-dimensional regular set’s zeros. We generalize the squarefree decomposition of univariate polynomials to the so-called pseudo squarefree decomposition of multivariate polynomials, and then propose an algorithm for decomposing a regular set into a finite number of simple sets. From the output of this algorithm, the multiplicities of zeros could be directly read out, and the real solution isolation with multiplicity can also be easily produced. As a main theoretical result of this paper, we analyze the structure of dual space of the saturated ideal generated by a simple set as well as a regular set. Experiments with a preliminary implementation show the efficiency of our method.

Digitalni dvojčki v ergonomskih ureditvah delovnih mest

t The approach to designing assembly lines and jobs in the modern world of Industry 4.0 is still too spontaneous. If we want to create a user-friendly workplace, it is necessary to include a myriad of variables with all the ergonomic principles. It is necessary to get involved in the process of progressive and holistic job design already in the phase of product design and the process of production and job design. Inadequate job planning can cause downtime in workflow engineering. If we want to be more efficient in product design, then we need to use the good experience of using digital twins. The experience of these and similar planning can be used for the preliminary design of a virtual workplace, where we can simulate the workload of employees, identify overloads and eliminate them already in the design phase. In this way, we are taking a big step towards streamlining jobs. In doing so, we avoid ergonomic slips, which are difficult to repair later. We are helped by modern tools, such as Tecnomatix JACK, ViveLab Ergo, NAWO ergo simulation, ..., with which we can generate, optimize, rationalize and implement a virtual solution in the marginal framework of a real solution.

Treatability tests of synthetic leachate from the Al-Hoceima city controlled landfill

Due to population growth and the intensification of economic activity, the production of solid waste is constantly increasing in Morocco [1]. Several programs consist of the establishment of controlled landfills and the rehabilitation of uncontrolled landfills. The impact of landfilling is the production of liquid effluents rich in organic, mineral, and metallic matter called leachate [2,3]. The choice of leachate treatment is based on the characteristics of the leachate. Any treatment process has advantages and limitations, so before proceeding with the treatment it is necessary to characterize the leachate to choose the appropriate process [11]. The objective of this study is to prepare synthetic leachate based on the characteristics of real leachate (case of the controlled landfill of Al Hoceima), in order to carry out treatability tests of this synthetic leachate by controlling the various parameters of analysis. This solution was made from organic (CH3CO2H, CH3CO2Na) and inorganic compounds (MgSO4, CaCl2, Ca(OH)2, NH4Cl, KOH, MgCl2), the various analyzes of this solution gave values comparable to the real solution. This work was devoted to carrying out the treatability tests of synthetic leachate by a process of adsorption on bentonite, by studying its yield to reduce the organic load.
