Published: June 2022

Abstract
In order to solve the problem of AGV fault detection system’s complexion and low accuracy, a convolutional neural network (CNN) based on the status monitoring and fault diagnosis method for automatic guided vehicle (AGV) is proposed. Firstly, the vibration signals of the core components of AGV are converted into two-dimensional (2D) images. Secondly, 2D images are input into convolution neural network for training. Finally, the trained model is used to monitor the running status of AGV and identify faults. The results show that the proposed method can effectively monitor the status of AGV in operation.

Abstract
This article summarizes research on the development and evaluation of a set of software usability measurements. Today they are called ”ergonomic criteria”. The authors summarize the research work carried out on the development and evaluation of a set of software usability measurements. The paper contains a description of each such criterion. All of them together provide a quality user interface. The authors highlighted the significant advantages of a well-designed and well-thought-out interface. The paper also contains an analysis of each of these criteria. The authors of the article discuss ergonomic problems of software development. As a result, some characteristics of the software are identified. They reduce the ergonomics of the user interface. The paper also discusses ergonomic issues and the things developers need to get rid of to make the app enjoyable. The success of solving this problem in software development largely depends on how functional, clear and user-friendly the interface is. The authors give some examples of bad user interfaces. They are accompanied by an explanation of the problems and solutions to these shortcomings. The systems, designed with practicality in mind, are ergonomic and work exactly as users expect, allowing users to focus on their own tasks rather than the specifics of interacting with the system.

Abstract
The information and communicative competency today is an integral part of professional training in any sphere. Due to the fact that nowadays big amount of work is done or monitored in the remote mode the requirement is stipulated for every specialist to be able to use digital technologies professionally. For a future seafarer it means, first of all, the ability to use modern technologies as the information and data resource and also it presupposes the ability to work with software libraries, to create data bases, to perform necessary calculations by means of cloud services inclusive. This component is of extreme practical importance as it enables the satisfaction of the social mandate to prepare future seafarers for the living in the information environment. The task is quite challenging so it requires the adequate knowledge level. That is why the main objective of the course “Information technologies” together with other subjects within the curriculum for the professional training in maritime academy is to develop the reliable scientific and methodological grounds for the realization of any professionally related tasks of future merchant feet officers. Specially selected tasks acquaint cadets with information technology in terms of implementing the solution of applied professionally oriented tasks, such as navigating the course, determining the location of the vessel, calculating stocks for the trip, etc. Therefore, the obligatory elements of the tasks are: construction of mathematical (computer) models;analysis of possible solutions to the problem; of technological processes, taking into account all factors influencing the process and methods of decision-making;implementation of mathematical models of problems in spreadsheets. This article proposes a strategy for solving an applied problem using an information-modeling approach to the analysis and evaluation of the technological process, namely, the algorithm for calculating the required voyage and storm fuel reserves of a marine vessel. Both office spreadsheets and cloud services were used to implement the mathematical model for solving this problem. The use of “cloud computing” technologies in the training of seafarers is due to the fact that, firstly, while on board, the master or ship mechanic can perform some components of their work, especially joint projects, in modern services, and secondly, these technologies, supporting traditional forms of education, is a new stage in the development of education and a cost-effective, efficient and flexible way to meet the needs of students in acquiring new knowledge.

Authors: Striuk A M , Semerikov S O 
Published: June 2022

Abstract
The article is devoted to one of the competence components of a mobile-oriented environment for professional and practical training of future software engineers. It is shown that the introduction of higher education standard 121 “Software Engineering” for the first (bachelor) level of higher education in Ukraine has generated a number of training quality assurance problems associated primarily with the low level of detailed competencies and program learning outcomes. By solving these problems, the detailed design of the system of professional competencies for future software engineers is developed. The article deals with the approaches to developing one of the most important special professional competences of future software engineers – the ability to participate in software design, including modeling (formal description) of its structure, behavior, and processes of functioning. Based on a historical and genetic review of the software engineering training practice of future software engineers in the USA, UK, Canada, Australia, New Zealand and Singapore, recommendations for choosing forms of training organization, selection of training content, ways of students’ and teachers’ activities in software engineering, modeling and designing tools; assessment of the appropriate competence formation level are formulated. The example of organizing design training in conditions close to industrial-studio training is considered. The problems of transition from architectural to detailed design and project implementation are shown. Prospects for further development of this study are to substantiate the third (after requirements engineering and design engineering) engineering component of software engineering – the software construction.

Published: June 2022

Abstract
The article presents an analysis of the phenomenon of “clip thinking” in the educational and cognitive activities of students of natural and physical-mathematical educational profile. The involvement of clip thinking in the initial stage of cognition in comparison with rational and theoretical thinking is theoretically substantiated. An empirical verification of the originality of cognitive processes of students of natural and physical-mathematical educational profile in the situation of comparing traditional linear (textual) and hypertextual way of presenting information is established. Deficiency of cognitive processes characteristic of clip thinking for results is revealed, which is characterized by characteristics of mental (theoretical) level of cognition. Therefore, the next stage of cognition should be the understanding of information through the mechanisms of comparison, generalization, categorization and re-synthesis.

Published: June 2022

Abstract
DAMPE is a space-borne experiment for the measurement of the cosmic-ray fluxes at energies up to around 100 TeV per nucleon. At energies above several tens of TeV, the electronics of DAMPE calorimeter would saturate, leaving certain bars with no energy recorded. In the present work we discuss the application of machine learning techniques for the treatment of DAMPE data, to compensate the calorimeter energy lost by saturation.

Abstract
neutron-gamma detection technology is widely used in nuclear
physics, high-energy physics, radiation medicine, and other
fields. A NaIL scintillator coupled with a silicon photomultiplier
(SiPM) can form a neutron-gamma detector with excellent
discrimination, small size, and low cost. However, the performances
of a NaIL scintillator and SiPM are affected by temperature, which
leads to a shift in energy spectrum and deterioration in
neutron-gamma discrimination. Most of the current studies have used
digitizers to store data and analyze detector energy spectrum and
waveform characteristics offline to eliminate temperature
dependence. In this study, a small neutron-gamma detector was
constructed using NaIL scintillators, SiPM, and circuits developed
in the laboratory. Online calibration of the ARM processor
eliminates the temperature dependence of the detector's energy
spectrum and neutron-gamma discrimination. Automatic energy spectrum
stabilization and good neutron-gamma discrimination were achieved in
a wide temperature range. The test results show that the peak shift
of the 137Cs 662 keV full-energy peak of the detector is
reduced from 5.3% to 0.4% at 0–50°C. After the online
correction of the temperature feedback PSD parameters, the figure of
merit at 45°C is 40% higher than that before the correction,
and the detector's figure of merit at 0–50°C is maintained
above 3.4.

Published: June 2022

Abstract
Bioprinting is an emerging approach for constructing sophisticated tissue analogues with detailed architectures such as vascular networks, which requires bioink to fulfill the highly printable property and provide a cell-friendly microenvironment mimicking a native extracellular matrix (ECM). Here, we developed a human placental ECM-derived bioink (hp-bioink) meeting the requirements of 3D printing for printability and bioactivity. We first decellularized the human placenta, followed by enzymatic digestion, dialysis, lyophilization, and re-solubilization to convert the extracts into hp-bioink. Then, we demonstrated that 3%–5% of hp-bioink can be printed with self-standing and 1%–2% of hp-bioink can be embedded and printed within suspended hydrogels. Moreover, hp-bioink supports human umbilical vein endothelial cell assembly in vitro and angiogenesis in mice in vivo. Our research enriches the bank of human-derived bioinks, and provides a new opportunity to further accelerate bioprinting research and application.
Ternary logic design in topological quantum computing
Authors: Ilyas Muhammad , Cui Shawn , Perkowski Marek 
Published: June 2022

Abstract
A quantum computer can perform exponentially faster than its classical counterpart. It works on the principle of superposition. But due to the decoherence effect, the superposition of a quantum state gets destroyed by the interaction with the environment. It is a real challenge to completely isolate a quantum system to make it free of decoherence. This problem can be circumvented by the use of topological quantum phases of matter. These phases have quasiparticles excitations called anyons. The anyons are charge-flux composites and show exotic fractional statistics. When the order of exchange matters, then the anyons are called non-abelian anyons. Majorana fermions in topological superconductors and quasiparticles in some quantum Hall states are non-abelian anyons. Such topological phases of matter have a ground state degeneracy. The fusion of two or more non-abelian anyons can result in a superposition of several anyons. The topological quantum gates are implemented by braiding and fusion of the non-abelian anyons. The fault-tolerance is achieved through the topological degrees of freedom of anyons. Such degrees of freedom are non-local, hence inaccessible to the local perturbations. In this paper, the Hilbert space for a topological qubit is discussed. The Ising and Fibonacci anyonic models for binary gates are briefly given. Ternary logic gates are more compact than their binary counterparts and naturally arise in a type of anyonic model called the metaplectic anyons. The mathematical model, for the fusion and braiding matrices of metaplectic anyons, is the quantum deformation of the recoupling theory. We proposed that the existing quantum ternary arithmetic gates can be realized by braiding and topological charge measurement of the metaplectic anyons.
