Performance Evaluation of Feature Extraction Algorithms for Vehicle Shape Classification
Authors: Patel Sunitha , Srinath S
Published: November 2022

Vehicle classification is a classic application of automotive image processing that is necessary for a variety of modern vehicle safety and comfort features. While machine learning-based solutions are effective in these fields and are currently employed extensively in various automotive applications. However, the most challenging aspect of automotive image processing with machine learning methods is gathering adequate quality and quantity datasets to develop such applications. Additionally, imbalanced datasets are common in multiclass automotive image processing, as is the case with the current topic of vehicle platoon management. The effectiveness of available handcrafted feature extractors and classifiers employed for vehicle class categorization varies greatly due to the effect of dataset imbalance. This study aims to examine how the performance of four prominent feature extractors alters when used with the imbalance dataset for vehicle shape classification. Also, the use of image augmentation techniques to increase the dataset size for three vehicle classes: car, bus, and truck, has been presented. Further, using the Support Vector Machine (SVM) classifier, experimental analysis was performed using feature extractors such as Histogram of Oriented Gradient (HOG), Scaled Invariant Feature Transform (SIFT), Speeded-Up Robust Feature (SURF), and Haar. Vehicle shape classification, which is an important characteristic in vehicle platoon management, has been evaluated using Receiver Operating Characteristic (ROC) for both the unbalanced dataset and the augmented dataset. The experimental results demonstrate that using the HOG feature extractor performs better when compared to SIFT, SURF, and HAAR feature extractors on the imbalance dataset. After using an image augmentation technique to add images, output performance improved significantly, with HOG output of 95%, SIFT output of 91%, SURF output of 91%, and HAAR output of 96%.

Published: November 2022

Distributed hybrid and electric propulsion systems are one of the most promising technologies to reduce aircraft emissions, resulting in research efforts to investigate new architectures and the design of optimal energy management strategies. This work defines the optimal requirements in terms of battery pack sizing and cell technology for a hybrid-electric regional wing-mounted distributed propulsion aircraft through the application of a design space exploration method. The propulsion system considered in this study is a series-parallel hybrid turboelectric power train with distributed electric fans. A set of six lithium-ion battery cell technologies was identified and experimentally characterized, including both commercially available and prototype cells at different combinations of specific energy and power. A model of the aircraft was developed and used to define the optimal energy management strategy for the hybrid turboelectric propulsion system, which was solved using dynamic programming. The design space exploration was conducted by varying the cell technology and battery storage system size; and the effects on fuel consumption, energy management strategy, and thermal management were compared.
Variable Noise Reduction Systems for a Notional Supersonic Business Jet
Authors: Berton Jeffrey J.
Published: November 2022

A variable noise reduction system consists of equipment on board an airplane that is designed to reduce noise in the vicinity of airports. They are anticipated to be used on supersonic civil aircraft currently under development by industry. They are investigated in this paper for a notional 55,000 kg supersonic business jet. The airplane concept was developed by NASA for use in environmental impact studies conducted by the International Civil Aviation Organization. The variable noise reduction system investigated implements a programmed thrust lapse procedure and a programmed flap retraction procedure. The procedures are expected to reduce noise in aircraft certification as well as in operational practice. Behavior of the aircraft in a noise certification setting is considered. Variables of the procedures are optimized to reduce noise levels. The optimization results in a reduction of 5.2 decibels (in the cumulative effective perceived noise level, measured in EPNdB) relative to levels reported previously. Certification considerations unique to these systems are discussed for transport-category large airplanes and jet-powered airplanes. A novel method for evaluating lateral noise is used.

Published: November 2022

When combustion instability occurs, the pressure oscillation will result in periodic change, not only in the injector flow rate but also in the atomization characteristics of the injector. In this work, atomization characteristics of swirl injectors under a standing-wave acoustic field were studied experimentally; the effects of acoustic pressure and injector position were analyzed on atomization and injectors characteristics in the critical state. It was found that under the same acoustic pressure, the effect of the acoustic field at the velocity antinode was stronger than the effect at the acoustic intensity antinode; and there was little effect at the acoustic pressure antinode. The hysteresis phenomenon of the spray field was also found in low flow rate cases in the acoustic field. The effects of the flow rate and liquid viscosity on atomization characteristics were analyzed, and the behavior of the Faraday wave was observed and studied during the experiment.
Cluster-Based Joint Distribution Adaptation Method for Debonding Quantification in Composite Structures
Authors: Zhou Xuan , Oboe Daniele , Poloni Dario , Sbarufatti Claudio , Dong Leiting , Giglio Marco
Published: November 2022

Adhesive bonding is widely adopted in aeronautic structures to join composite materials or to repair damaged substrates. However, one of the most common failure modes for this type of joint is debonding under fatigue loading. In the past years, it has been proven that deboning quantification is feasible, given that abundant experimental data are available. In this context, using domain adaptation to assist diagnostic tasks based on labeled data from similar structures or simulations would be thoroughly beneficial. However, most domain adaptation methods are designed for classifications and cannot efficiently address regressions. A fuzzy-set-based joint distribution adaptation for regression method has been developed by the authors, tackling regression problems but being limited to single outputs. The novelty presented in this paper exploits clustering techniques to approach multi-output problems, adopting a modified multikernel maximum mean discrepancy to improve the domain discrepancy metric. The proposed method is applied to cracked lap shear specimens to assist debonding quantification. Several domain adaptations are investigated: from simulations to experiments, and from one specimen to another, proving that the accuracy of damage quantification can be improved significantly in realistic environments. It is envisioned that the proposed approach could be integrated into fleet-level digital twins for nominally identical but heterogeneous systems.

В статье предложено новое описание повреждений черепа Сунгирь 1. Проверена гипотеза о появлении дефектов костной поверхности в процессе раскопок от воздействия лопатой при обнаружении могилы 1. Повреждения черепа Сунгирь 1 были исследованы методами компьютерной томографии и трасологии. Рассматривается история обнаружения и расчистки черепа Сунгирь 1, дается подробная классификация и стратиграфия следов воздействия на лобную кость черепа различными предметами в древности, в ходе раскопок и в лаборатории. Полученные данные позволили сделать вывод о том, что сквозное отверстие удлиненной миндалевидно-подтреугольной формы на лобной кости может быть уверенно интерпретировано как результат прижизненного проникающего ранения головы, которое и стало причиной смерти сунгирца.

Checking the preservation conditions of the bones from a male in Sungir grave 1 provided an opportunity to identify a mismatch between the injuries on the skull frontal bone and the traces left by a spade used during the discovery of grave 1. This triggered a study of the injuries with the use of computer tomography and traceology methods. The paper explores the history of Sungir 1 skull discovery and its cleanup, providing a detailed classification and stratigraphy of injury traces on the skull frontal bone left by various objects in prehistory, in the course of excavations and in the laboratory. The data obtained allowed the authors to conclude that a through hole of an elongated almondlike subtriangular form on the frontal bone can be interpreted with confidence as a lifetime penetrating injury of the head which caused death of this Sungir man.
Effect of Particulate Reinforcing Agents on Shore Hardness and Scratch Hardness of Polymeric Hybrid Blend Composites
Authors: Praharaj Bhatnagar Manoj
Published: November 2022

This paper explores the use of Wollastonite, Cloisite 20A, Hollow Glass Micro Spheres and Precipitated Silica as reinforcing fillers in PE-BA-GMA compatibilized blends of Hytrel with HDPE (60:40). Wollastonite has been treated with 3-glycidyloxypropyl trimethoxysilane (GPTMS), and its effect on dispersion and hardness has been studied via SEM. I have tried to understand how the aspect ratio, size and surface property of the filler affect its tendency to cause nucleation, or reinforce the composites. These effects have been corroborated with the shore hardness, scratch hardness, other mechanical properties and flammability. Additionally, DSC has been used to study the degree of crystallinity of the composites, which has been correlated with the mechanical properties of these composites.
Graphical understanding of electron delocalization and aromatic characteristic of unusual cyclo[18]carbon precursor, C18Br6
Authors: Wang Xia , Liu Zeyu , Wang Jiaojiao , Lu Tian , Xiong Weiwei , Yan Xiufen , Zhao Mengdi
Published: November 2022

The stable precursor C18Br6 is of more practical significance than the refreshing but elusive cyclo[18]carbon (C18) at present, and molecular aromaticity caused by π-electron delocalization is an important issue of interest for this unusual molecule. In this paper, the electronic structure and bonding character of the C18Br6 are thoroughly characterized by molecular orbital (MO), density of states (DOS), bond order (BO), and interaction region indicator (IRI) analyses. The delocalization characters of out-of-plane and in-plane π-electrons (πout- and πin-electrons) in bonding regions are examined using localized orbital locator (LOL) and electron localization function (ELF). The response properties of the molecule to external magnetic field including induced ring current and magnetic shielding characteristic are carefully explored with the anisotropy of current-induced density (ACID), iso-chemical shielding surface (ICSS), and gauge-including magnetically induced current (GIMIC). All these analyses showed graphically that the C18Br6 is less aromatic than C18 and the blocking of πin-conjugation system by the presence of -Br substituents is the underlying cause for the weakening of molecular aromaticity.
Molecular Mechanism of Spectral Tuning by Chloride Binding in Monkey Green Sensitive Visual Pigment

Published: November 2022

The visual pigments of the cones perceive red, green, and blue colors. The monkey green (MG) pigment possesses a unique Cl− binding site; however, its relationship to the spectral tuning in green pigments remains elusive. Recently, FTIR spectroscopy revealed the characteristic structural modifications of the retinal binding site by Cl− binding. Herein, we report the computational structural modeling of MG pigments and quantum-chemical simulation to investigate its spectral redshift and physicochemical relevance when Cl− is present. Our protein structures reflect the previously suggested structural changes. AlphaFold2 failed to predict these structural changes. Excited-state calculations successfully reproduced the experimental red-shifted absorption energies, corroborating our protein structures. Electrostatic energy decomposition revealed that the redshift results from the His197 protonation state and conformations of Glu129, Ser202, and Ala308; however, Cl− itself contributes to the blueshift. Site-directed mutagenesis supported our analysis. These modeled structures may provide a valuable foundation for studying cone pigments.

The modern educational game is in line with the new needs of children to provide the necessary opportunities and abilities – knowledge, skills, understanding, way of thinking in a new communication and information environment. Our experience in the last 10 years shows that today’s education in kindergarten is not limited to the development of competencies for the use of modern digital technologies, but implies knowledge and widespread use of computer technology and platforms. The creation, storage and use of such resources in the educational process depends on the creativity and innovation of the children’s teacher. Knowing the main characteristics of the game, we have developed educational games that are fun in nature and are determined by the presence of predifferentiated components.

MICROPLASTICS CONTENT IN ICE, SNOW AND UNDER-ICE WATER OF THE CURONIAN LAGOON IN WINTER 2021

Published: November 2022

Contamination of the water column, bottom sediments and beaches with small plastic particles (microplastics, MPs, < 5 mm) is currently being actively investigated, but data on ice and snow contamination are still very limited. The paper presents the results of the analysis of the number of MPs particles (0.3–5 mm) in ice cores, snow samples and underice water of the Curonian Lagoon (Baltic Sea), sampled at five stations on February 19, 2021. Higher ice contamination is confirmed: expressed in the number of MPs particles (0.3–5 mm) per 1 liter of (thawed or natural) water, it averaged at 66.4 items/l for snow, 90.5 items/l for ice and 9.1 items/l for under-ice water. Significantly increased amount of MPs particles (up to 281 items/l) were observed in the surface layer of ice (1.5–3 cm). This may in the given case be the consequence of the accumulation of contamination coming from the atmosphere: in the mild Baltic climate, the alternation of thaws and frosty periods favoures the formation of the upper layers of ice from the snow on it. The synthetic nature of the particles was confirmed by Raman spectrometry, which showed the presence along with polyethylene (15 %) also, a significant number of heavy types of plastics (polyurethane, polyvinyl acetate, polyacrylonitrile, etc., in total more than 24 %). Fibers made up about 95 % of the particles, films 1% and fragments – 4 %. The under-ice waters of the Curonian Lagoon, containing from 5.9 to 15.3 MPs particles per liter, turned out to be more than two orders of magnitude more contaminated than the waters of the Baltic Sea, having an average of 0.03 MPs particles per liter in the same particle’ size range. This confirms the general tendency of accumulation of MPs in bays and estuaries of rivers with limited water exchange with the sea.
