Improving the measuring length accuracy of articulated arm coordinate measuring machine using artificial neural network
Authors: Zhao Huining , Yu Liandong , Cao Jiaming , Jia Huakun , Jiang Yizhou
Published: December 2020

A new method for further improving the measuring length accuracy of the articulated arm coordinate measuring machine (AACMM) is proposed. The detailed procedure of the proposed method involves kinematic error calibration with the Levenberg–Marquardt algorithm and then non-kinematic error (such as link deflection, thermal errors, and error motions of the rotation shaft) compensation with a back-propagation neural network optimized by the mind evolutionary algorithm. In order to verify the effectiveness and correctness of the proposed method, the simulation and experiment were carried out on an AACMM. The simulated and experimental results demonstrate that the measuring length accuracy of the AACMM is improved significantly after kinematic error calibration and non-kinematic error compensation, confirming the effectiveness and correctness of the proposed method.
Pore-scale investigation of immiscible gas-assisted gravity drainage
Authors: Kong Debin , Lian Peiqing , Zhu Weiyao , Li Yiqiang
Published: December 2020

Gas-assisted gravity drainage (GAGD) is an effective method of oil recovery that is influenced by the properties of the fluids and formations involved. In this paper, a direct numerical simulation method is employed to investigate immiscible GAGD in an oil-wet porous medium. The interface between oil and gas is tracked via the phase-field method. A series of numerical simulations are performed over a large range of values of various factors (gravity force, capillary force, viscous force, viscosity ratio, and porous medium properties) to investigate the gas flooding process in a porous medium. The results show the oil–gas interface as a transition zone that migrates during the GAGD process. Gravity improves oil–gas interfacial stability because the continuous oil film gravity-assisted hydraulic connection effect can overcome the capillary force in a small pore. The oil displacement process is dominated by gravity instead of the capillary and viscous forces when the gravitational number exceeds 500. Finally, the pore-scale dimensionless number (Npore) enables a quantitative analysis of the effects of various factors on GAGD. Npore helps predict GAGD oil recovery.
Characteristics of a detached argumentative style in public policy analysis
Authors: Gâță Anca
Published: December 2020

This study is a contribution to the recently introduced notion of argumentative style (van Eemeren 2019) in the framework of the pragma-dialectical approach. It aims at characterizing a detached argumentative style,
by focusing on a speech event pertaining to the communicative activity type organizational discourse, a report on EU environment and climate
change policies. The analysis concerns the executive summary and the key findings of the report, reconstructed in the analysis as the
concluding stage of the critical discussion corresponding to the pragma-dialectical model. The notion of text type (Adam 1992) used in the analysis has allowed a more fine-grained characterization of the detached argumentative style,
especially since the communicative practice under analysis displays a specific discourse format and structure for reasons of
conventionalization and institutionalization. In such circumstances, determined by the type of conventionalization imposed by the context,
the adoption of a detached argumentative style appears to be a pre-requisite. In the concluding stage of a critical discussion the
difference of opinion is not restated, while the most significant standpoints are synthetically (re)presented by an adequate balance of
narrative, descriptive and metadiscursive text strategies meant to support the objectivity, the conciseness of the presentation and also
ensuring the necessary density of information required in a report summary or the presentation of key findings, respectively. While explicit
negative evaluations or formulations of standpoints are avoided, the recommendations are presented as open to adoption or reconsideration by
policymakers.
Las ironías clásicas y modernas en El río del Edén de José María Merino
Authors: Popovic Karic Pol
Published: December 2020

In the novel El río del Edén by José María Merino, the reader learns about the life experiences of Daniel
and Tere. This paper analyzes three stages in their lives: the camping trip, the period before the birth of their son Silvio and the
consequences of his medical condition on his parents. These critical moments have been seen from the ironic perspectives of classical and
contemporary philosophers: Socrates, Cicero, Kierkegaard, Muecke, Glicksberg and Robbe-Grillet, among others. The concept
eiron vs alazon, dissimulation, humor and incoherence are the theoretical tools that permitted this
study to bridge the gap between the literary text and the philosophical approaches to irony.

Published: December 2020

Vegetable production in Jamaica, and throughout the world, faces many diseases that affect the yield and the quality of the fresh harvest produce. However, some diseases are more predominant than others. The most observed diseases of vegetables are anthracnose, leaf spot, club root, downy mildew, gray mold, mosaic and geminiviruses, early blight, septoria leaf spot and leaf rusts. Nevertheless, other diseases can also be found seriously affecting the grown vegetable. Greenhouse cropping systems are also affected by similar and other diseases such as septoria leaf spot, early blight, anthracnose, fusarium wilt, verticillium wilt, late blight, bacterial spot, bacterial speck, bacterial canker, gray mold, leaf mold, powdery mildew and elephant’s foot disease. Although not specific to the country, other diseases are also found more frequently than others, and the frequency varies with the region and the cropping system (indoor or outdoor).
A typology of social characters and various means of control: an analysis of communication during the early stages of the corona pandemic in Germany
Authors: Seidenschnur Tim
Published: December 2020

This paper argues that Covid-19 has produced a set of social characters during the corona crisis and that these characters represent different approaches toward control. Social characters emerge as constructs responding to current discourses. They may function as role models in uncertain times and offer orientation. The paper identifies such characters in communication on the online platform Jodel. It analyses and discusses the properties of the following social characters, which are reconstructed inductively from the data, classifying 156 Jodel posts into the following typology: the social worker, the crisis entrepreneur, the worried and depressed loner, the crisis manager, the admonisher, and the health expert. All these characters also display different approaches to how the crisis could be controlled. Some of them highlight economic discourses, others psychological discourses, and again others bureaucratic discourses. The analysis of the social characters and their approaches to control contributes to research on the role of discourses in modern European societies and on how these discourses contribute to different approaches to controlling a crisis.

Published: December 2020

The development of tin-based perovskite solar cells (PSCs) is a promising approach to meet the demand of eco-friendly, lead-free perovskite photovoltaics. Limited to the poor chemical stability of tin perovskites, tin-based PSCs usually have to be fabricated with an inverted device structure and both the device efficiency and stability are highly dependent on the selection of hole transport materials (HTMs). Here, we report the synthesis of inorganic nickel oxide (NiO
x
) nanoparticles (NPs) via a soft base precipitation method, which enables us to obtain highly dispersed NiO
x
NPs over a wide pH window. The as-prepared NiO
x
NPs are employed as the HTM for formamidinium tin iodide (FASnI3) PSCs, resulting in excellent device efficiency (∼8%) and stability (1200 h). Our study offers a facile strategy for mass production of NiO
x
NPs and easy access to efficient and robust inorganic HTMs that could further boost the development of high performance tin-based PSCs.
‘Beneficial impurities’ in colloidal synthesis of surfactant coated inorganic nanoparticles
Authors: Abutbul Ran Eitan , Golan Yuval
Published: December 2020

Colloidal synthesis of nanoparticles (NP) has advanced tremendously over the past 25 years, with an increasing number of research papers introducing nanomaterials with a variety of compositions, shapes, sizes, and phases. Although much progress has been achieved, commonly used synthetic procedures often fail to reproduce results, and the fine details of the syntheses are often disregarded. Reproducibility issues in synthesis can be ascribed to the effects of impurities, trace amounts of chemical moieties which significantly affect the reaction products. Impurities in NP synthesis are rarely reported or regularly studied, despite their impact, deleterious, or beneficial. This topical review discusses several case studies of colloidal NP synthesis where the sources and the chemistry of impurities are highlighted, and their role is examined.

Authors: Zhang Yongjun , Zhu Aonan , Wang Yaxin , Zhang Xiaolong
Published: December 2020

Excessive thiram residues in food have the potential to negatively impact human health. Hence, the development of a convenient and fast detection method is highly desirable. In this study, an efficient, repeatable, and sensitive surface-enhanced Raman scattering (SERS) active chip was manufactured via a low-cost colloidal lithography technique. The plasmonic structure was composed of a series of silver nanospheres and nanowires. Interestingly, this type structure creates a nanocavity space with a characteristic geometry generating a strong electromagnetic field coupling. The finite-different time-domain software was employed to simulate the electromagnetic field distribute on the nanocavity. Accordingly, SERS active chip that displays ultra-low concentration detection of thiram (10−11 M) was realized. Moreover, the excellent reproducibility of thiram (10−6 M) practical detection on an apple pericarp has great potential for application in food safety.

Published: December 2020

Herein, a novel planar heterostructure (ITO/CeOx/CH3NH3Pb(I1–xClx)3/NiO/Au) of a CH3NH3Pb(I1–xClx)3-based perovskite solar cell has been designed and numerically investigated. CH3NH3Pb(I1–xClx)3 has been introduced as an absorber layer due to its excellent thermal stability and high carrier diffusion length. Inorganic CeOx and NiO have been introduced as an electron transport layer (ETL) and hole transport layer (HTL), respectively, as their role in the enhancement of efficiency and stability of other perovskite-based solar cells has already been proven. The influences of different physical parameters of the CH3NH3Pb(I1–xClx)3 absorber layer, NiO HTL, and CeOx ETL on the device performance have been explored. The investigated results indicate that the thickness and carrier concentration of the CH3NH3Pb(I1–xClx)3 has a massive impact on solar cell performance. A considerable impact of the carrier concentration of the CeOx and NiO on device performance has also been observed. The role of CH3NH3Pb(I1–xClx)3-layer deep-level defects, CeOx/CH3NH3Pb(I1–xClx)3 interface defects, series resistance, and back contact work functionon solar cell performance were also studied. The optimized solar cell exhibited a power conversion efficiency of 26.05% with open-circuit voltage (V
OC), short-circuit current density (J
SC), and fill factor of 1.082 V, 29.41 mA cm−2, and 81.85%, respectively. This research indicates that the designed heterostructure of solar cells may appear as a viable alternative to manufacturing CH3NH3Pb(I1–xClx)3 high-performance perovskites.

Authors: Hari Babu B , Rao P Srinivasa , Reddy M Gnaneswara
Published: December 2020

The physical aspects of flow and heat transport analysis of non-Newtonian (Carreau-Yasuda) fluid through an upper paraboloid surface of revolution has been scrutinized. Non-linear radiation, magnetic field, heat generation are considered in this study. The governing flow equations are modeled in the formulation. The governing flow equations (PDE’s) are changed into a system of ODE’s by employing the related transformation variables. The highly non-linear and coupled ODE’s are resolved aid of Runge–Kutta fourth-order along shooting numerical procedure. The physical flow and temperature phenomena have analyzed for both Newtonian and Non-Newtonian fluid cases through plots for the dimensionless sundry variables. The fluid velocity dwindled with the escalation of the magnetic field. An increase in fluid temperature is observed against the temperature ratio variable. Behaviour of fluid temperature of Newtonian fluid is excessive as compared to the Carreau-Yasuda fluid case for the exponential parameter N. The present model (Carreau-Yasuda fluid) is simplified to the viscous fluid (Newtonian fluid) case when n = 1. The streamline flow patterns are reduced for higher thermal Grashof number Gr. The numerical comparison has been deliberated with existing outcomes for a limit case. The heat augmentation analysis through Carreau-Yasuda liquid has prominent applications in non-linear science and industrial technology.

Published: December 2020

The fluid model, also called the macroscopic model, is commonly used to simulate low temperature and low pressure radiofrequency plasma discharges. By varying the parameters of the model, numerical simulation allows us to study several cases, providing us the physico-chemical information that is often difficult to obtain experimentally. In this work, using the fluid model, we employ numerical simulation to show the effect of pressure and space between the reactor electrodes on the fundamental properties of silicon plasma diluted with ammonia and hydrogen. The results show the evolution of the fundamental characteristics of the plasma discharge as a function of the variation of the pressure and the distance between the electrodes. By examining the pressure-distance product in a range between 0.3 Torr 2.7 cm and 0.7 Torr 4 cm, we have determined the optimal pressure-distance product that allows better deposition of hydrogenated silicon nitride (SiN

Published: December 2020

Fresnel incoherent correlation holography (FINCH) is a unique three-dimensional (3D) imaging technique which has the advantages of scanning-free, high resolution, and easy matching with existing mature optical systems. In this article, an incoherent digital holographic spectral imaging method with high accuracy of spectral reconstruction based on liquid crystal tunable filter (LCTF) and FINCH is proposed. Using the programmable characteristics of spatial light modulator (SLM), a series of phase masks, none of whose focal lengths changes with wavelength, is designed and made. For each wavelength of LCTF output, SLM calls three phase masks with different phase constants at the corresponding wavelength, and CCD records three holograms. The spectral images obtained by this method have a constant magnification, which can achieve pixel-level image registration, restrain image registration errors, and improve spectral reconstruction accuracy. The results show that this method can not only obtain the 3D spatial information and spectral information of the object simultaneously, but also have high accuracy of spectral reconstruction and excellent color reproducibility.
Teaching stochastics to bachelors of mathematics: computer simulation for conceptual understanding
Authors: Kuznetsova Elena , Zhbanova Natalia
Published: December 2020

The professional training of mathematics students is notable for the large volume and complexity of the content of educational material. In this regard, the problem of conceptual understanding is relevant. Since many concepts in mathematics have a high level of abstraction, studying them, it is essential to create an image of an object through various forms of knowledge representation. Computer simulation in the study of probability theory and its applications (stochastics) help students understand the essence of random phenomena and forms the ability to analyze statistical data. Students whose curriculum includes a computer simulations workshop in the study of stochastics, not only solve problems better but also higher evaluate the value of probabilistic ideas and methods and have a lower level of anxiety. Due to the use of simulations in teaching mathematics students on stochastics, we use a computer as a means of automation of calculations, means of learning, and a tool of knowledge, which corresponds to the principle of the integrated use of information computer technology in the educational process.

Published: December 2020

The use of computers to a certain extent devalues the role of manual calculations, but in the practice of mathematics education, the emphasis is still placed on the correct conduct of mathematical calculations. Therefore, in modern education, mathematics should be considered as a multifaceted multidimensional phenomenon, in which there are scientific, applied, historical and cultural, cultural and leisure, economic, management components. The education system should reflect the main aspects of mathematics, for which we propose to use a complex of its models. The article discusses several such models: activity, apparatus, phenomenological, process models of mathematics, two historical models of mathematics. An outline of their use for the design and evaluation of a study topic and a training course is made.

Authors: Sirotenko A N , Partko S A
Published: December 2020

The issue of training a future engineer in design and technology specialization is considered. For the effective assimilation of the acquired knowledge, improvement of the skills of using CAD and traditional design techniques in teaching the design and use of CAD, the principle of "end-to-end design" is applied. For a workshop in several disciplines, one task is used. This makes it easier for the student to adapt to the new discipline and accelerates its learning. When teaching a new discipline, a future engineer not only designs elements of an already known structure using CAD/CAE/CAM capabilities, but also corrects previously obtained design and technological solutions. Thus, not only new design skills are acquired, but the quality of the already acquired knowledge is improved.

Published: December 2020

The capabilities of modern information and communication devices (tablets, glasses, helmets, etc.) that provide user interfaces with Augmented Reality (AR) are successfully used in education and maintenance support nowadays. The main benefits are concerned with the possibility to display the required information in the context of operations performed by the user. Technically it is implemented in the form of textual hints or visual 3D objects with highly realistic appearance and behavior. New features prompt new challenges: the user can be easily overloaded with lots of information, and some real objects that require user’s attention can be overlapped by virtual ones in one scene. In order to solve this problem and improve the usability and effectiveness of AR devices application in maintenance and education it is proposed to build adaptive user interfaces that consider the context and focus of the user. From information technology perspective this approach forms a promising area of application of high-potential technologies including machine learning and computer vision. In this paper there is presented an example of AR implementation as a part of an interactive manual, which provides adaptation and personalization based on the concept of accented visualization. Identification of objects and their classification is implemented using the artificial neural network.

Published: December 2020

This article presents a model of a subsystem for performing practical tasks of an adaptive electronic learning resource (AELR) in the LMS Moodle environment. The authors consider the distinctive aspects of forming individual educational trajectories for the development of skills and abilities in studying the Control System Modeling course using the LMS Moodle instrumental apparatus. The paper presents an algorithm for developing the skills needed to perform the operations under study. The algorithm suggests step-by-step skill development through frequently repeated actions and gradually complicated tasks with the reducing time allotted for their solving. Further, the paper analyses experimental results concerning the introduction of the adaptive electronic learning resources into the educational process. It was found that higher involvement in the educational process and greater learning efficiency are observed in the experimental student group where the learning process was arranged through an adaptive electronic learning resource, as compared to the control group that participated in traditional classroom activities. It was also found that the application of the learning method using the adaptive electronic learning resources leads to statistically significant (at the level of 95% according to the chi-squared distribution) differences in the learning results.
Higher engineering education: traditions, regular and forced innovations
Authors: Andreev V V , Evdokimova O K , Gorbunov V I , Vasilieva L N
Published: December 2020

This paper focuses on the study of the features of distance learning at a university in light of modern requirements for higher engineering education and the traditions of the education in Russia. Education in Russia has always been understood not only as learning but also as enlightenment when the lecturer’s mission was not limited to teaching goals–it involved the moral and intellectual development of students. This research formulates and analyses a contradiction of the need to combine traditions of Russian education with a strengthening of the professional component of engineering education. The concept of «intelligence» is actualized as a desire for knowledge, humanism, selfless attitude to work and professionalism, high culture and moral qualities, developed sense of duty, social responsibility. Diversified personality development correlates with the concept of intelligence. In this regard, it is natural to turn to the transdisciplinary approach in the educational process in its expanded understanding as integration of not only the content and methods but also the forms of learning organization, as well as obligatory establishment of working contacts between lecturers of different disciplines. The paper formulates proposals for semi-formalized tests in force majeure conditions of distance learning.
