A simple online tool condition monitoring system using artificial neural networks
Authors: Mukherjee A , Das S 
Published: February 2021

Abstract
During machining occurrence of tool wear is a common phenomenon. As tool wear increases, rubbing of flank surface and workpiece also gets increased. Then, the desired quality of workpiece is not possible to achieve. To minimize this loss of quality, a cutting tool should be changed or ground after reaching certain amount of average flank wear (0.3 mm for uniform and 0.6 mm or non-uniform flank wear). For the detection of worn out state of a cutting tool, condition monitoring is required. During past decades, a lot of research works had been done on both offline and online monitoring of cutting tool. Most of the researchers used high cost setups and sensors for wear detection purpose. In this work, tool wear is detected using spindle speed as the wear detection parameter. Artificial Neural Networks is used as data analysing tool. Back propagation algorithm is used as learning algorithm. Results show that proposed methodology is capable to detect tool wear satisfactorily.

Published: February 2021

Abstract
Present paper deals with the numerical study of fluid flow and heat transfer due to an annular turbulent jet impingement on a flat heated plate. The geometrical configurations of annular jet was selected such a way that the mass and momentums efflux at the annular jet exit will be same as a circular jet having same inner diameter at a particular Reynolds number. Three dimensional turbulent flow field was resolved using Transition SST Model by solving the mass, momentum and energy equation with SIMPLE algorithm. A highly refined mesh was used for numerical computation after validation of present model with established results of same geometrical configuration. The flow structure and heat transfer characteristic of the annular jet was compared with the conventional circular jet and also with an established two dimensional study of same configurations and reported in this paper. It was observed that that two dimensional studies on annular jet under predicts heat transfer characteristics.

Published: February 2021

Abstract
The article aims at understanding the complex unsteady fluid dynamics in six generations of a human bronchial tree, which comprises of 63 straight sections and 31 bifurcation modules in a complete breathing cycle. The effects of 3-D arrangement on oscillatory flow is analyzed. Unsteady effects are maximum during the shift of expiration to inspiration and vice versa. It is also observed that the symmetry of the flow in cased of fully developed flow is destroyed due to unsteady effects. The flow division at the bifurcations causes a large asymmetry in the flow field during the inspiration than during the expiration process at the same cross-sections, thus displaying irreversibility of fluid dynamics. The second part of the study is aimed at analyzing the multiphase fluid dynamics inside a six generation bronchial tree for the case of an active smoker. Both the velocity magnitude contours and volume fractions of air and smoke is analyzed and it is observed that the general symmetry of the flow in the main two halves of the branching network is lost due to the interaction of smoke and air in the branches during inhalation and exhalation. It is also observed that higher mass of smoke is accumulated within the daughter branches which are at a lesser angular deviation with the trachea, whereas the branches at the extreme ends have little to no smoke deposit. This phenomenon can be attributed to the high smoke particulate density compared to that of air.

Authors: Pal Tarun Kanti , Chattopadhyay Himadri , Mandal Dipak Kumar 
Published: February 2021

Abstract
This work concern studies for the transport enhancement of impinging annular jets. The ribs are introduced on the impingement surface and higher heat transfer could be obtained using rib compared to plane surface. Comparison is made with circular jet to predict the enhancement of heat transport for same Reynolds number and mass and momentum efflux at jet outlet. The model used for solving the problem is Shear Stress Transport (SST) model, while the Reynolds numbers of jet varies from 100 to 50000. Square rib is used in this study. This study reveals that the ribs will increase the heat transfer for both circular and annular jets. Annular jet provides 20–30% lower heat transfer than that of the circular jet.

Abstract
The experience of design and construction of single-mesh spherical dome coverings based on meshes with triangular cells was studied. Constructive solutions of wooden domes made of triangular panels with orthotropic plywood covers are considered. The method analysis for constructing a bar model of an orthotropic plate in the form of an oblique triangle has been carried out. It is proposed to reduce the calculation of the triangular dome panel’s rod-sheet structure to the calculation of the hinge-bar system. The stiffness matrices of the contour and intra-contour rods of the super cell are obtained.

Authors: Kravchenko G M , Pudanova L I 
Published: February 2021

Abstract
On the basis of a specially developed algorithm, shaping of the fractal structures, the formation of which is regulated by the power index of the fractal, has been carried out. A sphere and an ellipsoid were used as the basic shapes. The formation analysis has made it possible to determine the characteristic principles of the fractal structure growth. The performed numerical experiment with respect to volumetric fractal structures of power 8 made it possible to determine the spectrum of frequencies and forms of natural oscillations. The offered objects of fractal architecture are analogs of unique high-rise and large-span buildings and structures. The application of the fractal shaping paradigm in combination with digital technologies and innovative materials will make it possible to create completely new objects of architecture.

Abstract
The article presents a new methodology for the complex assessment of factors that restrict working conditions, which is based on matrix mechanisms of complex assessment, allowing to take into account heterogeneous complexity factors. As criteria for determining the cramped working conditions, the following are used: the mass and dimensions of the inventory, their number and the complexity of work to prepare the workplace for construction and installation work. The presented approach is able to take into account any factors‘ combination, which makes it possible to abandon the existing fixed number of coefficients. Illustrated examples are shown and that clearly demonstrates the methodology for assessing the complexity of construction and installation work. The proposed method can be used in the management of construction projects, to adjust the cost of work, etc. The screen forms of the software module created specifically to provide a comprehensive assessment of complexity factors are demonstrated.

The vibrations of a nonlinear, absorbing soil ground calculation by the method of the seismic microzoning multiple-reflected waves
Authors: Zaalishvili V B 
Published: February 2021

Abstract
A nonlinear version of the program ZOND (nonlinear) has been developed based on the dependence of the shear and absorption modulus values on the seismic impact intensity, as well as on the introduction of ratios for calculating various indicators of soil movement (normal stress, deformation, etc.). The program algorithm is based on the multiple-reflected waves theory. An accelerogram of an earthquake, recorded on a rocky ground in Japan with earthquake characteristics similar to those for the territory of Tbilisi (magnitude, epicentral distance, spectral features, etc.), was chosen as an accelerogram set into the bedrock from the generated strong motion database AGESAS. The results of linear and nonlinear calculations with and without absorption are presented. It is clearly seen that with an increase in the intensity of the impact, the nonlinearity manifestation increases. At the same time, absorption increases. In this regard, the resulting movement at very high levels of impact may be below the initial level. This corresponds to the facts known from the analysis of the consequences of strong earthquakes that have occurred in recent years.

Published: February 2021

Abstract
The research results showed that the problem of resource saving during the chromium electroplating from standard electrolyte can be solved. Formulated requirements that ensure the implementation of the set tasks without costs for new equipment and chemical reagents. It has been proved that organic compounds of a certain structure introduced into the electrolyte influence the chromium electroplating in such a way that all technological characteristics, coating properties, physical and chemical characteristics of the solution change. The chrome plating process has been optimized using the experimental mathematical planning method, which made it possible to develop methods for obtaining chrome coatings protected by security documents on the basis of experimental data. All the proposed methods allow solving the problem of resource saving and environmental safety. The authors have consistently studied resource-saving and environmental indicators. In galvanic chromium plating technology, resource-saving indicators are: energy intensity; metal intensity; water intensity; and labour intensity. Environmental indicators: industrial emissions: gas emissions, waste water; occupational diseases.

Aeroelastic deformation measurement of Martian airplane for high-altitude flight experiment using stereophotogrammetry
Authors: Hiramatsu Shuichi , Anyoji Masayuki , Fujita Koji , Nagai Hiroki , Oyama Akira , Kato Hiroyuki 
Published: February 2021

Abstract
A fixed-wing aircraft called Mars Airplane Balloon Experiment −2 (MABE2) developed by the authors was the subject of high-altitude flight demonstration test in this paper, which can simulate the near-actual environment of a Martian atmospheric flight. Although the flight condition is in the low-Reynolds-number region due to low density at high altitude, the wing suffers from aeroelastic deformation given the relatively high dynamic pressure load in the pull-up phase. Stereophotogrammetry was applied in the 6.5 m × 5.5 m low-speed wind tunnel at the Japan Aerospace Exploration Agency (JAXA), aiming to optically measure MABE2’s aeroelastic deformation under dynamic pressure loads equivalent to high-altitude flight test, with the MABE2’s reinforced structural strength. The results of the accuracy test indicated that stereophotogrammetry measures aeroelastic deformation at high accuracy of ±0.1 mm around the image center and ±0.3 mm around the edge. A slight deflection of up to 4 mm was observed on the main wing, whereas both the main and tail wings were hardly twisted. Compared with flight-simulation-assumed errors, these deformations are extremely small and have a negligible effect on the high-altitude flight test. The study results confirmed the practicality and efficiency of this optical measurement technique in aeroelastic deformation measurement for a real light aircraft.

Authors: McGilton Katherine S , Krassikova Alexandra , Boscart Veronique , Sidani Souraya , Iaboni Andrea , Vellani Shirin , Escrig-Pinol Astrid 
Published: February 2021

Abstract

Background and Objectives
There is an urgency to respond to the longstanding deficiencies in health human resources in the long-term care (LTC) home sector, which have been laid bare by the coronavirus disease 2019 (COVID-19) pandemic. Nurse practitioners (NPs) represent an efficient solution to human resource challenges. During the current pandemic, many Medical Directors in LTC homes worked virtually to reduce the risk of transmission. In contrast, NPs were present for in-person care. This study aims to understand the NPs’ roles in optimizing resident care and supporting LTC staff during the pandemic.

Research Design and Methods
This exploratory qualitative study employed a phenomenological approach. A purposive sample of 14 NPs working in LTC homes in Ontario, Canada, was recruited. Data were generated using semistructured interviews and examined using thematic analysis.

Results
Four categories relating to the NPs’ practices and experiences during the pandemic were identified: (a) containing the spread of COVID-19, (b) stepping in where needed, (c) supporting staff and families, and (d) establishing links between fragmented systems of care by acting as a liaison.

Discussion and Implications
The findings suggest that innovative models of care that include NPs in LTC homes are required moving forward. NPs embraced a multitude of roles in LTC homes, but the need to mitigate the spread of COVID-19 was central to how they prioritized their days. The pandemic clearly accentuated that NPs have a unique scope of practice, which positions them well to act as leaders and build capacity in LTC homes.
Rewarding Subjective Effects of the NMDAR Antagonist Nitrous Oxide (Laughing Gas) Are Moderated by Impulsivity and Depressive Symptoms in Healthy Volunteers

Published: February 2021

AbstractBackgroundNitrous oxide (N2O) is an anesthetic gas with both therapeutic and abuse potential. Because N2O is an NMDA receptor (NMDAR) antagonist, its effects are expected to resemble those of the prototypical NMDAR antagonist, ketamine. In this study, we examined the subjective rewarding effects of N2O using measures previously employed in studies of ketamine. We also tested for moderation of these effects by bipolar phenotype, depressive symptoms, and impulsivity.MethodsHealthy volunteers were randomly assigned to either 50% N2O (n = 40) or medical air (n = 40). Self-reported rewarding (liking and wanting), and alcohol-like effects were assessed pre-, peri- and post inhalation.ResultsEffect sizes for the various rewarding/alcohol-like effects of N2O were generally similar to those reported in studies of moderate-dose ketamine. Impulsivity moderated the subjective reinforcing (liking) effects of inhaled gas, while depressive symptoms moderated motivational (wanting [more]) effects. However, depression and impulsivity had opposite directional influences, such that higher impulsivity was associated with higher N2O liking, and higher depression, with lower N2O wanting.ConclusionTo the extent that static (versus longitudinal) subjective rewarding effects are a reliable indicator of future problematic drug use, our findings suggests that impulsivity and depression may predispose and protect, respectively, against N2O abuse. Future studies should examine if these moderators are relevant for other NMDAR antagonists, including ketamine, and novel ketamine-like therapeutic and recreational drugs. Similarities between moderate-dose N2O and moderate-dose ketamine in the intensity of certain subjective effects suggest that N2O may, at least to some extent, serve as substitute for ketamine as a safe and easily implemented experimental tool for probing reward-related NMDAR function and dysfunction in humans.
