A flexible framework for web-based virtual reality presentation of cultural heritage

AIP Conference Proceedings 2021年第1期2333卷

The Virtual Reality (VR) experiences are great for an engaging presentation creating wide public awareness of cultural heritage, especially if the experience is built on a web-based technology. One of the still posing challenges is that once an application has been developed, for example for a virtual museum or a virtual tour, it usually remains fixed to an embedded in the application model. Adding new functionalities or interaction paradigms needs additional development and new deployment. In this paper, we propose a framework, which achieves the decoupling of an experience from the used models and interaction paradigms through scene and input templates and configuration files. This allows an easy way for generation of a variety of experiences even by people with no or limited programming skills.

—The mathematical model for many problems is arising in different industries of natural science, basically formulated using differential, integral and integro-differential equations. The investigation of these equations is conducted with the help of numerical integration theory. It is commonly known that a class of problems can be solved by applying numerical integration. The construction of the quadrature formula has a direct relation with the computation of definite integrals. The theory of definite integrals is used in geometry, physics, mechanics and in other related subjects of science. In this work, the existence and uniqueness of the solution of above-mentioned equations are investigated. By this way, the domain has been defined in which the solution of these problems is equivalent. All proposed four problems can be solved using one and the same methods. We define some domains in which the solution of one of these problems is also the solution of the other problems. Some stable methods with the degree p © 2021, North Atlantic University Union NAUN.

Optical Bloch Equations (OBE) describe the coherent exchange of energy between a quantum bit (qubit) and a quasi-resonant driving field in the presence of a thermal bath. Despite it being an ubiquitous process in quantum technologies, a sound thermodynamic analysis is still missing. We hereby provide such an analysis, by deriving the relevant framework from first principles. We start from a complete microscopic description of the qubit-bath system where definitions of heat, work and entropy production are unambiguous. We trace out the bath and coarse-grain the resulting expressions in time, using a methodology similar to the derivation of the dynamical master equation, to derive closed expressions for the First and Second Law in terms of system properties. Long coarse graining times yield the Floquet Master Equation and its already known thermodynamic description. Short coarse-graining times yield instead to the OBE and a novel thermodynamic framework which explicitly depend on quantum coherences in the qubit’s energy basis which produce quantum signatures in the heat and entropy production flows. This allow us to characterize a genuinely quantum non-equilibrium situation, where the coherences created by the driving field are continuously erased by the bath. Our findings can be readily extended to larger open quantum systems. They carry the seeds for future thermodynamic analyses of quantum gates and the design of quantum engines in the strong coherent driving regime. Copyright © 2020, The Authors. All rights reserved.

In article the research of dynamics of change of electromagnetic parameters of the controlled special electric drives is conducted. Special electric drives are the controlled cascade electric drives of cylindrical and axial designs. The research of dynamics of change of parameters was executed to a basis of a method of electromagnetic transformation of energy and the theory of electromagnetic chains. As a result for new mathematical models of an electromagnetic system of the research electric drives parameters of the electromagnetic field of the closed round of one coil of an electric winding with electric current in a homogeneous environment are determined. The solved task is spatial as distribution of electromagnetic induction in a round of the set form of the electromagnetic coil is defined. The received conclusions of determination of electromagnetic parameters of cylindrical and axial electric motors of special electric drives allow to solve correctly problems of modeling, design and improvement of efficiency of the research electric drives and other electromechanical converters of energy of various designs. Results of a research are applicable for creation of the computer-aided engineering system of the research electric drives and the solution of problems of modeling and design. The conducted research allows to create electric drives optimum mass-dimensional and power indicators.

To search for new technical solutions when designing color measuring systems, we need a design object, i.e. to divide color measuring device into fragments, and solutions are sought for these fragments separately. At the first level of the partition, the color measuring device is divided into four main structural parts: the lighting, dispersing, electronic recording and computing devices.

Effective application of Augmented Reality user interfaces is one of the challenging trends of industrial cyber-physical systems development and implementation. Despite reach functionality of modern AR devices (like goggles, head mounted displays or tablets) the problem of their comfortable and productive use is not completely solved yet. To cover this gap, it is proposed in this paper to implement a new paradigm of 'accented visualization' that allows adapting additional data presented by AR device according to the user's current interest, attention and focus. To provide such context driven functionality there was developed intelligent software based on eye tracking and capturing the user's focus in ontology as a knowledge base. Probation and testing of the proposed approach present 89 % of the solution efficiency. © 2018 IEEE.

The main challenge in estimating human velocity from noisy Inertial Measurement Units (IMUs) are the errors that accumulate by integrating noisy accelerometer signals over a long time. Known approaches that work on step length estimation are optimized for a specific application, sensor position, and movement type, require an exhaustive (manual) parameter tuning, and can thus not be applied to other movement types or to a broader range of applications. Moreover, varying dynamics (as they are present for instance in sports applications) cause abrupt and unpredictable changes in step frequency or step length and hence result in erroneous velocity estimates. We use machine learning (ML) and deep learning (DL) to estimate a human's velocity. Our approach is robust to varying motion states and orientation changes in dynamic situations. On data from a single un-calibrated IMU, our novel recurrent model not only outperforms the state-of-the-art on instantaneous velocity (≤0.10 m/s) and on traveled distance (≤29 m/km). It can also generalize to different and varying rates of motion and provides accurate and precise velocity estimates.

An overview of existing urban software mobile applications of the transport and economic direction is given. A model of a functional rationalizer of consumer behavior is being built. The software model of the functional rationalizer of consumer behavior (SM FRCB) was developed for the first time. PMFRCB allows the user to expand the number of his preferred needs (occupations, activities) during the daily cycle through intelligent recommendations. Also, SM FRCB allows you to optimize needs (activities, activities) at the cost and rate of their use. The SM FRCB is made in Python_3 using the libraries matplotlib, collections, numpy, pyplot, mplot3d. The analysis of consumer behavior before and after using the functional rationalizer model is carried out. The graphical results of a structural analysis of the costs of old and new consumer behavior, analysis of consumer behavior within the boundaries of the theory of possibilities and the model of transport behavior of a resident before and after applying the functional rationalizer model are presented. The prospects of further improving the SM FRCB are considered.
