A Simple Mathematical Model and Computer Simulation of Non-isothermal Gas Absorption in Packed Tower
Authors: Chen Zhiqin
Published: February 2021

Oxygen-enriched combustion technology can effectively achieve residual capture, but the existence of acid gases such as NOx and SOx is not conducive to the transportation and storage of CO2. The compression of CO2 discharged from the packed tower is a necessary process before transportation. Therefore, the study of combined desulfurization and denitrification of flue gas under high pressure is of great significance to the application of carbon capture and storage technology. Based on the mass transfer coefficients obtained from experiments, a coupled model of mass transfer and kinetics of the bubbling reactor is established for the combination of reaction mechanism and kinetics of non-isothermal gases, and this unsteady state problem is solved by the Runge-Kutta mathematical method. The simulation study of the product changes in the process of NO and SO2 absorption alone and combined absorption under different pressures. The results show that: the interaction of NOx and SOx in the liquid phase promotes the absorption of SO2, NO2 and the mass production of

The Metaphor Processing and Translation Skills of Computer Technology in English Language Translation
Authors: Hou Zhiyuan
Published: February 2021

From the study of language grammar in our country, the metaphor we can understand refers to a form of written expression that is rich in linguistic narrative skills. Going back to the history of ancient literature, we will find that the ancient people’s understanding of metaphor is not just a simple way of language description, it is a language form of human active thinking and flexible thinking. I have to say that the use of language grammar can add a lot of color to the article. In the process of English translation, many authors also like to use the grammatical form of metaphor to express the meaning of the article[1]. For the translation of English articles, the form of computer literal translation is relatively simple. However, for English writing similar to metaphorical techniques, whether computer-assisted translation skills can use metaphorical Chinese techniques for translation in time is also a point that researchers should emphasize and pay attention. This article explains some related problems of English-based computer-assisted Chinese metaphor translation from the cultural differences between Chinese and foreign cultures and customs. It is hoped that researchers on English translation can learn from or put forward different opinions.

Aspects regarding the increase of the protection level of the falling-object protective structures (FOPS) by using the post-critical behavior of the support elements
Authors: Dumitrache P , Goanță A M
Published: February 2021

For earth-moving machinery which are operated in areas with danger of falling objects on its cabin, an important performance requirements imposed on the machine is the protection of the human operator in case the cabin is hit by a falling object. As a result, the mechanical system formed by the cab’s strength structure and its supporting elements must have the ability to dissipate high impact energies, so that the deformed system does not penetrate the deflection limiting volume (DLV). In general, the support on the chassis of the falling-object protective structures is rigid, so almost all impact energy is dissipated in the deformation of the cabin’s strength structure. The present article proposes that most of the impact energy be dissipated in the post-critical deformation of some dissipative removable supporting elements interposed between the chassis of the machine and the falling-object protective structure. In addition, the article proposes the numerical evaluation of the post-critical behavior of the analyzed mechanical system, using finite element analysis. The first part of the article briefly presents the main regulations in the field of falling-object protective structures, as well as the methods of approaching the evaluation of the performances imposed on these structures, with their advantages and disadvantages. Following are given the main aspects of the optimal modeling of structures for numerical analysis of their behavior, the particularities of numerical evaluation of post-critical behavior and some constructive solutions of dissipative elements. The final part of the article is dedicated to a case study and the author’s conclusions.

In the present work, the premature rupture of a spring used in the aviation sprag overrunning clutch of the helicopter was analyzed based on the general method for failure analysis by use of the investigations of the fracture surface, mechanical and chemical performance as well as the microstructure of the spring material. The results showed that spring breakage is mainly caused by mechanical fatigue. The cracks and fracture originated from internal surface of the spring, and the cracks extended from outside surface of the spring toward the external surface of the spring, which was consistent with the direction of tensile residual stress on the internal surface of the spring. The marks of the shot peening were obvious on the outer surface, while the inner surface had obvious metal flow lines, indicating that the residual tensile stress formed on the internal surface of spring. Moreover, the oxide inclusions were also detected on the internal surface of spring. It can be noted that the stress concentration on the spring internal surface and oxide inclusions are responsible for the fracture of the spring.
Effect of five versus two axle moving trucks on structural dynamic performance of frame bridges
Authors: Mohammed A , Almansour H
Published: February 2021

Recent advances in analysis, and design approaches led to a considerable reduction of the structural elements’ size and weight. Heavy multi-axle trucks are now standardized in North America, and elsewhere, the traffic speed and the average number of trucks passing bridges have dramatically increased. For the purpose of the design and/or assessment of bridge structures, it is imperative to evaluate the static deformations, frequency, vibration amplitudes, and dynamic deformation patterns of new and aged bridges due to the new five-axle versus the old two-axle design trucks. This study investigated the effects of using a recent standard multi-axle design truck on the dynamic performance of a frame bridge. It presents a comparison of the bridge dynamic performance under 2-axle and 5-axle moving trucks. A two-dimensional nonlinear finite element model is used to model the frame, and trucks are modelled as a multi-degree of freedom dynamic system integrated with the bridge model. It is found that the model is able to capture the local dynamic excitation and oscillations results from the high variation of the stiffness and mass of the bridge components.
Empirical correlation of heat generation in hybrid ball bearings, depending on the operational conditions in the aero-engine rotor supports

Modern gas turbine bearings operate at high rotational speeds. Their speed index reaches dmn=3…3, 5-106 mmrpm, where dm = bearing mean diameter, and n = rotational speed. At high speeds, significant heat is generated in conventional steel bearings, and substantial cooling oil consumption may be required. A promising solution to this problem is using hybrid bearings with steel rings and ceramic rolling elements. Due to ceramic’s relatively small coefficient of thermal expansion, hybrid bearings retain radial clearance in a wide temperature range. Hybrid ball bearings, with an inner diameter of 130mm and 150mm, were tested in the bearings test rigs at the Central Institute of Aviation Motors (CIAM). From these tests, an empirical method for determining the thermal state of the bearings was developed. The calculated values correspond well with the experimental data presented in the extant literature.

OWL2, a widely-used ontology-representation language, is poorly perceived by humans because OWL2 statements have a low level of abstraction. To solve this issue, various OWL2 ontology editors are used, which allow to group statements and represent them using some visual notation. ORM-diagram is a good candidate for an intermediate model for authoring and understanding of OWL2-ontology as Object-Role Modelling notation supports visually distinguishable constructs, has the high expressive capabilities, and implements the node-link paradigm and the attribute-free approach A Protégé plugin allowing to create an ORM2-diagram using the live error checking approach was implemented. The plugin allows us to form a valid object-oriented diagram model in computer memory using a widely known ontology authoring tool Protégé.

Techniques for reducing dimensionality of attribute space
Authors: Petrovsky A B
Published: February 2021

The paper describes techniques for reducing the dimensionality of attribute space where objects are represented as vectors, tuples and multisets with numerical and/or verbal characteristics. In these tools, many initial attributes are aggregated into a single integral index or several composite indicators with small scales of qualitative estimates. Aggregation of indicators includes various methods for transformation of attributes and their scales. Reducing the dimensionality of attribute space allows us to simplify the solution of applied problems, in particular, problems of multiple criteria choice, and explain the obtained results.
Sub-band identification of speech signals word fragments according to given sample

Published: February 2021

The article considers the problem of the speech signals fragments, generated when pronouncing a certain word form, emphasis in the recordings, which is of the interest from the position of the speech information exchange analysis solvable applied problem. In this case, it is assumed that initially the class of the desired word form is given by the fragment available in the real speech signal recording. Therefore, it is natural to term the problem under consideration as precedent identification. The relevance of the methods and algorithms development for automatic precedent identification of voice recordings fragments in such situation is determined by the breadth of their possible applications, for example, in information and analytical security systems. The variability of the speech signals fragments properties, even generated when pronouncing the same word form by the same person, and the need to learn from one precedent in determining the critical areas of decisive functions are the main factors that determine the complexity of solving this problem. It is shown in this paper that sub-band analysis is an adequate basis for solving the problem under consideration, and an original mathematical apparatus was developed for its implementation. On the basis of original sub-band representations, the decision procedures for identification of speech signals recordings fragments, including the selection of pauses between word fragments, were developed. In particular, training procedures were proposed for one precedent while maintaining its original sub-band properties.
