Rarity meters are incorporated by industry and discursive by academia. Rarity, as an intuitive term, attracted numerous researchers to present their own view of it. While there is existing literature on comparing rarity meters, it requires access to NFT collection data, which can be challenging for researchers without a background in blockchain technology. This has created a demand for an easily accessible rarity meter benchmark. In this paper, we introduce the Rating over all Rarities (ROAR) benchmark, which includes data from one hundred popular NFT collections from the Ethereum blockchain, implemented a weighted correlation-based performance measurement function, as well as four state-of-the-art rarity meters (***, Kramer, OpenRarity, and NFTGo), along with a new rarity meter called ROAR. Our experiments show that the ROAR rarity meter, an ensemble of the other four meters, outperforms its competitors, with *** and Kramer as runner-ups. The ROAR benchmark is a tool for examination and testing of rarity meter ideas, and we challenge readers to develop models that can outperform the ROAR rarity meter. © 2024 IEEE.

Zero-one laws for random k-partite graphs

We study the validity of the first-order zero-one law for the binomial k-partite random graph in two settings: dense (the probability p of appearance of an edge is a constant) and sparse (p = n^−α, where n is the cardinality of each part of the graph). On the way, we prove that, for every rational ρ ≥ 1, there exists a bipartite strictly balanced graph with density ρ. © 2022, Mathematical Science Publishers. All rights reserved.

Rendering high-polygonal models from distant perspectives has certain performance issues related to high density of subpixel triangles, which can be solved by levels of detail, a classical optimization method. Since a mesh occupies a small area on the screen, an alternative representation of the geometry in the form of a point cloud can replace the original geometry with little or no change to the image, and allowing for significant performance improvements due to the smaller number of primitives rendered. This paper presents a method for automatically generating a point cloud from a polygonal mesh with nested levels of detail. It also considers a method for rendering cloud with dynamically varying cloud density in real time based on view frustum and distance. © 2024 University of West Bohemia. All rights reserved.

Optimization of routine processes increases production efficiency. However, such a rapid disruption of habitual everyday processes prevents timely adaptation to new reality and creates preconditions for social instability. AI-based technologies are beginning to replace human resources, but a substantial number of people lack an understanding of alternatives for their efforts application. If previously there was just automation of production processes that did not affect sphere of creativity and did not affect decision-making areas, now there is a concern that the creative side of the profession will also be replaced. The jewelry profession is a creative profession with many bifurcation points at each stage. In this regard, the sphere can serve as a good example for understanding how people negotiate to coexist in changing socio-technological conditions. The article provides a qualitative study of comments from the expert community of jewelers and expert interview analisys on the topic of using artificial intelligence in the field of jewelry manufacturing. Jewelry art requires years of training: mastering skills in modeling (both digital and material), sketching, casting, soldering, metal rolling, stone work, enamel work, etc. Nowadays there are opportunities to transfer these skills to AI. The analysis covers expert comments for December 2024 and January 2025. Comments were clustered on the base of statements made. The most frequently mentioned theses were identified. The result is a diagram of a new social interaction as part of a potentially new social contract. © 2025 IEEE.

Composite metamorphic relations for integration testing 22

Composite metamorphic relations for integration testing

Metamorphic testing is a testing method for problems without test oracles. Integration testing allows for detecting errors in complex systems that may not be found during the testing of their components. In this paper, we propose a novel approach that applies metamorphic testing in integration testing. The main idea is to develop a composite metamorphic relation for the system represented as an acyclic graph. This relation is a logical function of metamorphic relations for the parts of the system (vertices of the graph). It takes into account the features of the parts. Also, it can simplify the search for failure by identifying the subsystem with error. In this paper's theoretical part, we describe an algorithm of relation design. Then, we apply our method to a bioinformatics system for comparative genetic analysis of tissues using production tools. This experiment proves our method can be applied to real-life pipelines and find errors in them. © 2022 ACM.

Mean-field approximation techniques are widely used to model dynamics of large complex stochastic systems, which are extremely difficult to describe using precise equations. However, in the context of the modelling of social systems, such an approach may lead to inaccurate solutions, as real-life social networks feature structurality whereby individuals form their ego-graphs not at random. Resulting social networks are modular and tend to include dense groups of vertices-communities-whose presence may seriously affect various processes in networks, including information dissemination, innovation diffusion, and opinion formation. Besides this, communication networks that establish on social media platforms display substantial activity heterogeneity and are subject to individuals' cognitive biases and the moderation by personalization systems. In this vein, naive aggregation techniques may fail to cope. This paper considers a model that describes how a structured population of individuals update their opinions following pairwise stochastic interactions. For this model we develop a mean-field approximation that accounts for all the roadblock factors mentioned above and investigates the key properties of the resulting master equation.

This work presents a numerical investigation of acoustic cavitation in Newtonian fluid based on frequency ultrasound. The model of ultrasonic cavitation dynamics is formulated by a modified Rayleigh-Plesset equation and an acoustic pressure equation. The exponential B-Spline collection method was employed to obtain the numerical solutions of the given cavitation bubble model, considering the effect of acoustic pressure. The behaviour of the cavitation microbubbles' radius and the internal pressure of acoustic cavitation were examined at different values of frequencies. The obtained results reveal the importance of frequencies in ultrasound, which play a vital role in changing the behaviour of cavitation bubbles. © 2023 IEEE.

This paper proposes a semi-Markov model of telecommunication network (TCN). The variant of dynamic traffic adaptive control of queuing system as a special case of TCN is considered. The main purpose of control is to minimize the average cost per unit of time to service the incoming flow of information (packets). This takes into account the different bandwidth of the channels, the processing speed of information in the channel and the information capacity of the buffers. The approach to the organization of dynamic control taking into account noise immunity (information reliability) and information security is discussed. © 2024 IEEE.
