Opis:
This paper investigates properties of single- and double-layer pad coatings deposited on cultivator points. The coatings were deposited by manual metal arc welding (MMA) with ESAB OK. 84.58 coated electrodes using an inverter welder, DEDRA DESi201. Tribological properties were determined with a THT 1000 tribometer. A ball-on-disc friction pair was used. Experiments were performed in room temperature, with the sliding speed set equal to 0.3 m/s and two loads: 5 and 20 N. In addition, hardness was measured on the surface and in the cross section of samples by a Rockwell hardness test method (scale C). Surface roughness was measured before and after friction, and post-friction surface topography was examined under microscope. Impact strength tests of the coatings with single- and double layers of pads were performed. The tools and IT algorithms were used to collect and process the results of experimental research.

Opis:
The paper presents a process of testing a created virtual reality application for displaying the "Hujra", a room for students of the 17th century madrassa in the area of the Silk Road, together with interactive objects. The designed 3D objects had sufficiently small file sizes to be introduced into virtual reality, and the fully mobile application worked effectively using smartphones within the price group available to the average user. The application was presented to a group of students and researchers from Kyrgyzstan. In addition, objects not belonging to the Islamic culture were introduced into the students' room. Pilot tests confirmed the usefulness of the proposed solution of 3D modelling. Interviews with the participants of the experiment and the results of a survey showed that the virtual reality application was a very attractive form of presentation, especially for people belonging to Generation Z. The combination of the complexity of the project and its high availability via smartphones was considered a successful solution by those questioned.

Opis:
The availability of 3D scanning devices allows performing the process of digitisation of a growing number of diverse museum artefacts. After the properly conducted processing of the acquired point cloud, the authors obtained a photorealistic digital copy that can be presented in many ways. With regard to the objects from archaeological excavations, the vast majority are the artefacts that are more or less damaged or only partially preserved. Their state of preservation, specialised archaeological knowledge and the use of appropriate 3D computer technologies allow their complete digital reconstruction. The present work concerns the development of alternative methods and algorithms of conduct, the selection of programs and tools to recreate the surface of the outer and inner side and the bottom of a 12th century pitcher from the Afrasiab excavations in Uzbekistan.

Opis:
Counteracting the social and educational exclusion of visually impaired people is an important issue in the area of knowledge transfer, also in the area of cultural heritage. Visually impaired people get to know the world in an organoleptic way, where the leading cognitive factor is touch. This type of cognitive method cannot be used in museology and historical architecture. Current attempts to solve this problem lead to the use of additive technology understood as 3D printing. The paper presents a modified procedure for obtaining digital 3D models with the use of Autodesk Inventor version 2021, dedicated to creating scalable replicas of architectural objects using additive technology. The applied procedure uses the decomposition of the object into its components and the acquisition of data from terrestrial 3D laser scanning (FARO Focus 3D scanner, Faro Scene software). Printing in the Fused Filament Fabrication technology of a designed minaret representing the architecture of the Timuridian period (minaret of the Ulugh Beg Madrasa in Samarkand, Uzbekistan), originating from the Silk Road area, was carried out due to the size of the facility, divided into several parts. The obtained replica of the minaret was presented to people with simulated pattern dysfunction and tested in a pilot test. The obtained results confirmed that the decomposition of the object for the purposes of 3D modelling, the diversified scaling of individual elements to make real 3D replicas of the digital model facilitated the kinesthetic recognition of the relevant architectural object for the respondents.

Opis:
3D printing of historic architectural objects reduces the entire digital model by up to 200 times. With this scaling of the digital 3D model, many important architectural and decorative details are lost, and some elements lose their stiffness. Printed 3D models are now used to create specialised museum exhibitions that allow visitors to get to know them kinesthetically. This ability to touch objects applies not only to visually impaired people, but to all interested visitors. The paper describes the preparation of a digital 3D model (D3DM) dedicated to 3D printing by decomposing the real model into sub-models and using different scaling values for individual elements. The practical part presents three-dimensional modelling of historic architectural objects of Lublin and their replicas made on 3D printers in the Fused Filament Fabrication (FFF) technology. Virtual models designed in this way retain important details of objects and are also scalable as a whole, which allows for obtaining printed objects of various dimensions.

Opis:
The aim of the work was to develop a computer program that allows identification of polymer materials that are used in 3D printing technology. The computer program was made using the algorithm that concerns the method of thermal polymer degradation. Filament samples were prepared for this purpose and then set on fire. The collected data on the flammability of polymers was used in an algorithm that can make a decision to identify the name of the polymer. The software can be used to identify polymer prints used for 3D printing technology. The computer program supports the process of recycling plastics and supports ecological work.

Systemy nawigacyjne to zaawansowane narzędzia, które pozwalają tworzyć postacie inteligentnie poruszające się po świecie gry. W ramach niniejszej pracy przeprowadzono analizę porównawczą autorskiego systemu nawigacji o nazwie AlchemyNavigation oraz wbudowanego narzędzia silnika Unity - systemu NavMesh. Do przeprowadzenia badań wykorzystano autorską aplikację zbudowaną przy pomocy silnika Unity, w ramach której zaimplementowano tożsame scenariusze badawcze bazujące na porównywanych systemach. Finalnie, na podstawie zebranych wyników oraz dokumentacji badanych systemów zrealizowana została analiza porównawcza, która dowiodła tezy że własne rozwiązania mogą dorównać rozwiązaniom domyślnym, a także, że pozwalają wprowadzać nowe funkcjonalności.
Navigation systems are advanced tools that allow you to create characters intelligently moving around the game world. The purpose of this thesis was to conduct a comparative analysis of the proprietary navigation system “AlchemyNavi-gation” and the built-in tool of the Unity engine - “NavMesh”. An proprietary application created with the Unity engine was used to conduct the research, under which identical scenarios based on the tested systems were implemented. Finally, on the basis of the collected results and documentation of the research objects, a comparative analysis was carried out and proved the thesis that own solutions can match the default solutions.

Opis:
This paper evaluates the wear characteristics of hardfacing coatings. Regenerative hardfacing coatings were applied with the TIG (Tungsten Inert Gas) method. The solid welding wires were used to obtain the coatings marked as: EL-500 HB, EL-650 HB, and EL-3348. The tribological analysis of samples was conducted at room temperature. The wear rate was evaluated with a THT 1000 Anton Parr ball-on-disc tribotester, in accordance with the ASTM G-133 standard. The counterbody (static partner) consisted of balls with the diameter of 6 mm made of Al2O3. The test was performed with the sliding speed of the friction pair 0.4 m/s, track radius 10 mm, normal load 20 N, acquisition rate 10 Hz and sliding distance 2000 m. During the test, the friction coefficient and wear rate were recorded. The multi-criteria assessment of the construction materials discussed, while taking into account five criteria, showed that EL-3348 HB is the best material. Computer applications were used for multi-criteria assessment and statistical processing of data.

Opis:
Celem poniższego artykułu jest zaprezentowanie zapomnianego dziś zjawiska plądrofonii. Omawiane zagadnienie jest awangardowym podejściem do odbioru i wykorzystywania cudzych dzieł muzycznych w celu nadania im nowych znaczeń, poprzez stworzenie własnych wersji. Efekty plądrofonii można przyrównać do kolaży muzycznych. Autor zestawia tę koncepcję z samplingiem, który jest powszechnym działaniem na współczesnym rynku muzycznym. Przedstawiana jest postać Johna Oswalda, autora opisywanego pojęcia, jego filozofia i efekty działań. W tym kontekście wprowadzone zostaje pojęcie aktywnego słuchania. Autor omawia także postać Christiana Marclaya, który jako obiekt przetworzeń plądrofonicznych wybrał nośniki dźwięku – głównie płyty winylowe. W tekście znajduje się także opis narzędzi wykorzystywanych przez autorów dzieł plądrofonicznych. Poruszony zostaje aspekt konsekwencji prawnych działań Oswalda, z jednoczesnym wprowadzeniem pojęcia kultury remiksu, wymyślonym przez Lawrence’a Lessiga. Autor przywołuje też przykłady dzieł plądrofonicznych na współczesnym rynku muzycznym oraz duchowych spadkobierców plądrofonii, których możemy odnaleźć w przestrzeni kultury internetowej.
The goal of this article is to present a nowadays forgotten concept of plunderphonics. Relevant subject is an avant-garde approach of listening and using existing music pieces to give them new meaning by creating own works. Effects of plunderphonics can be equated with the concept of musical collage. The author combines this idea with sampling, which is commonly used in the music industry. In the context of the article’s theme, the author depicts the character of John Oswald, who is responsible for creating plunderphonics. His philosophy and effects of his works are presented along with the idea of active listening. Another person mentioned in the article is Christian Marclay who was physically manipulating vinyl records to create musical collages. There is also a presentation of technics which are used by musicians creating plunderphonic music. Legal consequences of John Oswald’s work are presented, along with the term of remix culture, by Lawrence Lessig. The author shows the examples of the plunderphonic works in today’s music industry, and it’s spiritual ancestors, which can be found in the internet culture.
