Authors: Madhiarasan Manoharan , Cotfas Daniel T. , Cotfas Petru A.
Published: September 2022

The goal of this research is to accurately extract the parameters of the photovoltaic cells and panels and to reduce the extracting time. To this purpose, the barnacles mating optimizer algorithm is proposed for the first time to extract the parameters. To prove that the algorithm succeeds in terms of accuracy and quickness, it is applied to the following photovoltaic cells: monocrystalline silicon, amorphous silicon, RTC France, and the PWP201, Sharp ND-R250A5, and Kyocera KC200GT photovoltaic panels. The mathematical models used are single and double diodes. Datasets for these photovoltaic cells and panels were used, and the results obtained for the parameters were compared with the ones obtained using other published methods and algorithms. Six statistical tests were used to analyze the performance of the barnacles mating optimizer algorithm: the root mean square error mean, absolute percentage error, mean square error, mean absolute error, mean bias error, and mean relative error. The results of the statistical tests show that the barnacles mating optimizer algorithm outperforms several algorithms. The tests about the computational time were made using two computer configurations. Using the barnacles mating optimizer algorithm, the computational time decreases more than 30 times in comparison with one of the best algorithms, hybrid successive discretization algorithm.

Authors: Drozdowicz Jedrzej , Samczynski Piotr
Published: September 2022

This paper presents a trajectory determination and optimization method of multirotors equipped with a single-channel radar to obtain 3D Synthetic Aperture Radar imaging. The result is a realistic trajectory that allows to obtain an imaging of the assumed quality in less time than using a multi-pass trajectory. The optimization criteria, in addition to the cross-range resolution, are the Peak Sidelobe Ratio (PSLR), Integrated Sidelobe Ratio (ISLR), and time of flight. The algorithm is based on a realistic motion model of the radar platform. This paper presents all the steps of the algorithm and provides simulation results that show its practical applicability. The advantage of the presented approach over the existing ones is indicated and further research directions are proposed.
FEA-Swin: Foreground Enhancement Attention Swin Transformer Network for Accurate UAV-Based Dense Object Detection
Authors: Xu Wenyu , Zhang Chaofan , Wang Qi , Dai Pangda
Published: September 2022

UAV-based object detection has recently attracted a lot of attention due to its diverse applications. Most of the existing convolution neural network based object detection models can perform well in common object detection cases. However, due to the fact that objects in UAV images are spatially distributed in a very dense manner, these methods have limited performance for UAV-based object detection. In this paper, we propose a novel transformer-based object detection model to improve the accuracy of object detection in UAV images. To detect dense objects competently, an advanced foreground enhancement attention Swin Transformer (FEA-Swin) framework is designed by integrating context information into the original backbone of a Swin Transformer. Moreover, to avoid the loss of information of small objects, an improved weighted bidirectional feature pyramid network (BiFPN) is presented by designing the skip connection operation. The proposed method aggregates feature maps from four stages and keeps abundant information of small objects. Specifically, to balance the detection accuracy and efficiency, we introduce an efficient neck of the BiFPN network by removing a redundant network layer. Experimental results on both public datasets and a self-made dataset demonstrate the performance of our method compared to the state-of-the-art methods in terms of detection accuracy.

Published: September 2022

This two-experiment study aimed to examine the effects of different habitual foot placement angles and also the effects of manipulating the foot placement angle on the kinetics, three-dimensional kinematics and muscle forces of the squat. In experiment 1, seventy lifters completed squats at 70% of their one repetition maximum using a self-preferred placement angle. They were separated based on their habitual foot angle into three groups HIGH, MEDIUM and LOW. In experiment 2, twenty lifters performed squats using the same relative mass in four different foot placement angle conditions (0°, 21°, 42° and control). Three-dimensional kinematics were measured using an eight-camera motion analysis system, ground reaction forces (GRF) using a force platform, and muscle forces using musculoskeletal modelling techniques. In experiment 1, the impulse of the medial GRF, in the descent and ascent phases, was significantly greater in the HIGH group compared to LOW, and in experiment 2 statistically greater in the 42° compared to the 21°, 0° and control conditions. Experiment 2 showed that the control condition statistically increased quadriceps muscle forces in relation to 0°, whereas the 0° condition significantly enhanced gluteus maximus, gastrocnemius and soleus forces compared to control. In experiment 1, patellofemoral joint stress was significantly greater in the HIGH group compared to LOW, and in experiment 2, patellar and patellofemoral loading were statistically greater in the control compared to the 42°, 21°, 0° and control conditions. Owing to the greater medial GRF’s, increased foot placement angles may improve physical preparedness for sprint performance and rapid changes of direction. Reducing the foot angle may attenuate the biomechanical mechanisms linked to the aetiology of knee pathologies and to promote gluteus maximus, gastrocnemius and soleus muscular development. As such, though there does not appear to be an optimal foot placement angle, the observations from this study can be utilised by both strength and conditioning and sports therapy practitioners seeking to maximise training and rehabilitative adaptations.

Published: September 2022

Attention is a complex cognitive process with innate resource management and information selection capabilities for maintaining a certain level of functional awareness in socio-cognitive service agents. The human-machine society depends on creating illusionary believable behaviors. These behaviors include processing sensory information based on contextual adaptation and focusing on specific aspects. The cognitive processes based on selective attention help the agent to efficiently utilize its computational resources by scheduling its intellectual tasks, which are not limited to decision-making, goal planning, action selection, and execution of actions. This study reports ongoing work on developing a cognitive architectural framework, a Nature-inspired Humanoid Cognitive Computing Platform for Self-aware and Conscious Agents (NiHA). The NiHA comprises cognitive theories, frameworks, and applications within machine consciousness (MC) and artificial general intelligence (AGI). The paper is focused on top-down and bottom-up attention mechanisms for service agents as a step towards machine consciousness. This study evaluates the behavioral impact of psychophysical states on attention. The proposed agent attains almost 90% accuracy in attention generation. In social interaction, contextual-based working is important, and the agent attains 89% accuracy in its attention by adding and checking the effect of psychophysical states on parallel selective attention. The addition of the emotions to attention process produced more contextual-based responses.
TNT Loss: A Technical and Nontechnical Generative Cooperative Energy Loss Detection System
Authors: Calamaro Netzah , Levy Michael , Ben-Melech Ran , Shmilovitz Doron
Published: September 2022

This paper describes an electricity technical/nontechnical loss detection method capable of loss type identification, classification, and location. Several technologies are implemented to obtain that goal: (i) an architecture of three generative cooperative AI modules and two additional non-cooperative AI modules for data knowledge sharing is proposed, (ii) new expert consumption-based knowledge of feature collaboration of the entire consumption data are embedded as features in an AI classification algorithm, and (iii) an anomaly pooling mechanism that enables one-to-one mapping of signatures to loss types is proposed. A major objective of the paper is an explanation of how an exact loss type to signature mapping is obtained simply and rapidly, (iv) the role of the reactive energy load profile for enhancing signatures for loss types is exemplified, (v) a mathematical demonstration of the quantitative relationship between the features space to algorithm performance is obtained generically for any algorithm, and (vi) a theory of “generative cooperative modules” for technical/nontechnical loss detection is located and mapped to the presented system. The system is shown to enable high-accuracy technical/nontechnical loss detection, especially differentiated from other grid anomalies that certainly exist in field conditions and are not tagged in the universal datasets. The “pooling” architecture algorithm identifies all other loss types, and a robotic process automation module obtains loss type localization. The system feeds from the entire smart metering data, not only the energy load profile. Other solutions, such as a stand-alone algorithm, have difficulty in obtaining low false positive in field conditions. The work is tested experimentally to demonstrate the matching of experiment and theory.
WCNN3D: Wavelet Convolutional Neural Network-Based 3D Object Detection for Autonomous Driving
Authors: Alaba Simegnew Yihunie , Ball John E.
Published: September 2022

Three-dimensional object detection is crucial for autonomous driving to understand the driving environment. Since the pooling operation causes information loss in the standard CNN, we designed a wavelet-multiresolution-analysis-based 3D object detection network without a pooling operation. Additionally, instead of using a single filter like the standard convolution, we used the lower-frequency and higher-frequency coefficients as a filter. These filters capture more relevant parts than a single filter, enlarging the receptive field. The model comprises a discrete wavelet transform (DWT) and an inverse wavelet transform (IWT) with skip connections to encourage feature reuse for contrasting and expanding layers. The IWT enriches the feature representation by fully recovering the lost details during the downsampling operation. Element-wise summation was used for the skip connections to decrease the computational burden. We trained the model for the Haar and Daubechies (Db4) wavelets. The two-level wavelet decomposition result shows that we can build a lightweight model without losing significant performance. The experimental results on KITTI’s BEV and 3D evaluation benchmark show that our model outperforms the PointPillars-based model by up to 14% while reducing the number of trainable parameters.
Failed Mimicry: The Thai Government’s Attempts to Combat Labor Trafficking Using Perpetrators’ Means
Authors: Kranrattanasuit Naparat , Sumarlan Yanuar
Published: September 2022

(1) Background: This research paper examines the prevention measures, i.e., the application of technologies such as those abused by “traffickers”, used by government and non-government agencies to combat “internal trafficking” in Samut Sakhon province. The authors review numerous research papers and documents at international and national levels. (2) Methods: the authors use in-depth interviews to relate the anti-internal trafficking measures of the government and non-government agencies. (3) The findings show that these government and non-government agencies have attempted to combat “inter-border” trafficking and internal trafficking. However, limited information and communication gaps in the application of IT-based technology and other media for communication have caused unsatisfactory preventive results and responses against such phenomena. (4) Some findings point to the limited success of an NGO (the Labor Protection Network) whose leader decided to recruit Burmese- and Lao-speaking staff to reach out to potential and actual victims among Burmese and Laotian people. (5) The authors suggest that government agencies learned from this failure and then collaborated more with non-government and migrant worker organizations to provide sufficient information and efficient communication channels to ensure migrant workers’ safety in Thailand’s territory.

Proton irradiations are highly sensitive to spatial variations, mainly due to their high linear energy transfer (LET) and densely ionizing nature. In realistic clinical applications, the targets of ionizing radiation are inhomogeneous in terms of geometry and chemical composition (i.e., organs in the human body). One of the main methods for proton range monitoring is to utilize the production of proton induced positron emitting radionuclides; these could be measured precisely with positron emission tomography (PET) systems. One main positron emitting radionuclide that could be used for proton range monitoring and verification was found to be 13N that produces a peak close to the Bragg peak. In the present work, we have employed the Monte Carlo method and Spectral Analysis (SA) technique to investigate the feasibility of utilizing the 13N peak for proton range monitoring and verification in inhomogeneous targets. Two different phantom types, namely, (1) ordinary slab and (2) MIRD anthropomorphic phantoms, were used. We have found that the generated 13N peak in such highly inhomogeneous targets (ordinary slab and human phantom) is close to the actual Bragg peak, when irradiated by incident proton beam. The feasibility of using the SA technique to estimate the distribution of positron emitter was also investigated. The current findings and the developed tools in the present work would be helpful in proton range monitoring and verification in realistic clinical radiation therapy using proton beams.

EXPERIMENTAL MEASURES TO IMPROVE THERMAL CHARACTERISTICS IN DOUBLE-SIDED FACE GRINDING MACHINES
Authors: Nikitina I. , Polyakov A. , Voronin D.
Published: September 2022

The results of full-scale and computational experiments to improve the thermal characteristics of the machine tool are presented. This can lead to a decrease or achieve symmetry of the resulting thermal deformations. The implementation of four schemes for the redistribution of heat fluxes is considered: the heat flux of the main electric motors, directed under the protective casing of the drive pulley, and the heat flux of the belt drive are removed through special windows in the casing to the environment; jointly with the first scheme of redistribution of heat fluxes, cooling of the ends of the grinding headstocks is provided with the help of an impeller fixed on each drive pulley; jointly with the second scheme, heat flux isolation from the left and right electric motors is provided; heating the ends of the machine tool bed. The first three schemes are implemented at idling of the machine tool; the fourth scheme is implemented when the machine is operating under thermal load. The joint implementation of three schemes makes it possible to reduce the displacement of the right circle at idle by 1.5 times, the left circle practically did not move. The test of the first three circuits during the operation of the machine tool under a thermal load does not reveal significant changes in the thermal characteristics. The implementation of the fourth heat flux redistribution scheme help to compensate for thermal deformations from heating in the central part of the bed and reduce changes in the angular position of the grinding wheels.
INFLUENCE OF THE PARAMETERS OF AN ALUMOSILICATE ADDITIVE BASED ON MOUNTAIN SAND ON THE PROPERTIES OF SULFATE-RESISTANT PORTLAND CEMENT
Authors: Vasileva D. , Popov A. , Mestnikov A.
Published: September 2022

The paper substantiates the effectiveness and prospects of research in the direction of developing an active mineral additive based on mountain sand of Yakutia for general construction cements in order to increase its sulfate resistance. This will expand the range of application of Portland cements operating in conditions of sulfate aggression. The Republic of Sakha (Yakutia) has many deposits of natural sands of aluminosilicate composition or the so-called "mountain sands". One of the large and developed quarries of mountain sands in Yakutia is the Kildyamskoye deposit. Today it is used for foundations and underlying road surfaces. The paper shows the possibility of obtaining an active mineral additive based on this sand. The influence of the dosage and dispersion level of the additive on the strength characteristics of cements and on the coefficient of sulfate resistance is studied in the range of 5±2 % while maintaining brand strength. The introduction of an additive of more than 15 % reduces the strength of cement by an average of 20%, the grade strength is no longer observed, while hydration processes slow down and over time in a sulfate environment, the strength of the samples first increases and then falls again. As a result of the work, an active mineral additive based on the sand of the Kildyamskoe deposit in cement is proposed. This gives a stable sulfate resistance coefficient equal to 0.95 while maintaining brand strength and hydration processes.
INFLUENCE OF MINERAL FILLERS ON THE LIQUISHING OF CEMENT SYSTEMS WITH THE HELP OF SURFACTANTS
Authors: Tolypina N. , Tolypin D.A.
Published: September 2022

The effectiveness of the action of anion-active superplasticizers in mineral suspensions based on powders with different electrical surface properties has been studied. It is shown that in suspensions with positively charged particles (marble) the best thinning effect is observed. At the same time, in suspensions based on powdered quartz with a predominantly negative sign of the particle surface charge, the effectiveness of the action of superplasticizers is significantly reduced. It has been established that it is possible to increase significantly the diluting ability of anionic modifiers (by 40-68%) in quartz suspensions by introducing calcium carbonate (5%) during their joint grinding. The increase in liquefaction is due to the fact that blocking of negatively charged active centers of quartz sand is observed during joint grinding with CaCO3. It is shown that the electrosurface properties of the powdered filler have a secondary effect on the liquefaction of the cement paste with a filler composition of 1:1, since hydroaluminate particles with a positive surface charge have a predominant effect on the liquefaction. The electrical surface properties of the filler significantly affect the stability of the diluting ability of the joint venture over time due to heterocoagulation reactions with charged particles of the hydrated phases of Portland cement. It is shown that the strength of powder concretes with 10 and 30% fillers depended on the type of material used.

It describes the conditions of material movement in the granulation chamber, which is presented as a system of differential equations for the movement of a viscous incompressible fluid in a cylindrical coordinate system. The results of the theoretical studies carried out are confirmed by physical modeling of the technological process of granulation. According to the study of the conditions of movement of the material in the granulation chamber, it is conclude that the rate of shear deformations of the material layer across the width of the chamber varies unevenly, that is, the degree of freedom of the particles in it is limited. A solution is proposed to eliminate this disadvantage by creating more favorable conditions for the implementation of granulation processes, which can be created in a toroidal or close to it in shape chamber due to the intensification of the volumetric and spatial movement of the material.

Microbial contributions to natural soil suppressiveness have been reported for a range of plant pathogens and cropping systems. To disentangle the mechanisms underlying suppression of banana Panama disease caused by
Fusarium oxysporum
f. sp.
cubense
tropical race 4 (Foc4), we used amplicon sequencing to analyze the composition of the soil microbiome from six separate locations, each comprised of paired orchards, one potentially suppressive and one conducive to the disease. Functional potentials of the microbiomes from one site were further examined by shotgun metagenomic sequencing after soil suppressiveness was confirmed by greenhouse experiments. Potential key antagonists involved in disease suppression were also isolated, and their activities were validated by a combination of microcosm and pot experiments. We found that potentially suppressive soils shared a common core community with relatively low levels of
F. oxysporum
and relatively high proportions of Myxococcales, Pseudomonadales, and Xanthomonadales, with five genera,
Anaeromyxobacter
,
Kofleria
,
Plesiocystis
,
Pseudomonas
, and
Rhodanobacter
being significantly enriched. Further,
Pseudomonas
was identified as a potential key taxon linked to pathogen suppression. Metagenomic analysis showed that, compared to the conducive soil, the microbiome in the disease suppressive soil displayed a significantly greater incidence of genes related to quorum sensing, biofilm formation, and synthesis of antimicrobial compounds potentially active against Foc4. We also recovered a higher frequency of antagonistic
Pseudomonas
isolates from disease suppressive experimental field sites, and their protective effects against banana
Fusarium
wilt disease were demonstrated under greenhouse conditions. Despite differences in location and soil conditions, separately located suppressive soils shared common characteristics, including enrichment of Myxococcales, Pseudomonadales, and Xanthomonadales, and enrichment of specific
Pseudomonas
populations with antagonistic activity against the pathogen. Moreover, changes in functional capacity toward an increase in quorum sensing, biofilm formation, and antimicrobial compound synthesizing involve in disease suppression.

Type Locality of Walcott's Brigham Formation, Box Elder County, Utah
Authors: Sorensen Martin L. , Crittenden Max D.
Published: September 2022

The Brigham Formation was defined by Walcott, who gave as its type locality only the very · generalized location: "West front of the Wasatch Range, northeast of Brigham, Box Elder County, Utah." In 1971 the Brigham was elevated to group rank and defined as comprising a conformable sequence of Precambrian Z and Early Cambrian rocks. Recent detailed mapping of Brigham Group rocks in and near Walcott's type area has shown that these rocks are cut by the Box Elder thrust, a fault that has removed some 1,500-3,300 feet (450-1,000 m) of Precambrian Z rocks. It is now thought that Walcott's probable type section was above the Box Elder thrust and that Walcott's type Brigham can be correlated with essentially all of the Geertsen Canyon Quartzite, an Early Cambrian(?) unit whose type section is near Huntsville, Utah, 16 miles (25 km) southeast of Brigham City
Classification of Ripple Marks
Authors: High Lee R. , Picard M. Dane
Published: September 2022

Although ripple marks are extensively used in paleogeographic and environmental reconstructions, there is no generally accepted classification of them. The few formal classifications that have been proposed and the many informal classifications that have been used commonly recognize two major classes of ripples: current and either wave or oscillation types. Despite the seeming simplicity of this system, confusion has arisen because usage varies considerably. In some cases the same ripple type has been called current, wave-formed, or oscillation ripples by different authors. To resolve this problem we propose a classification that recognizes four major ripple types: wave formed, current formed, interference, and eolian. Three of the groups are aqueous, the fourth eolian. Within each group several varieties are distinguished. The most common varieties are: (wave-formed) oscillation, linear, and wave-dominated combined-flow; (current-formed) cuspate, linguoid, dune, antidune, and current-dominated combined-flow; (interference) tadpole nest, ladderback, cuspate and secondary, and rhomboid; and (eolian) sand ripples. Common names are retained, even where past usage is ambiguous, because they are descriptive and already in general use. Each ripple variety is readily identified by descriptive criteria that are related to mode of formation. Thus the classification is both genetic and descriptive. Accordingly, the ripple types can be identified objectively and also are useful for environmental reconstructions.

Folk Tales of the Namakkal Region in the System of Vladimir Yakovlevich Propp
Authors: G Ramesh , R Suresh
Published: September 2022

In the development of Tamil literature, a wide variety of literary genres of various structures have emerged from time to time. Genres of literature that have flourished and developed in one period have declined and disappeared in later periods. This will be in accordance with the likes and dislikes of the people and according to their needs. At the beginning of the 20th century, structuralism was developed in linguistics and then gained influence in various academic fields and was used in various fields such as literature, folklore, anthropology, social sciences, etc. In this way, the structural analysis approach was also used in folktales. Thus, the purpose of this article is to examine the folk tales collected in the Namakkal region in line with the structural theory of Propp.
