Authors: Moreira Hélio , Ferreira Luís Pinto , Fernandes Nuno O. , Ramos Ana Luísa , Ávila Paulo
Published: December 2023

Boarding time constitutes a critical element of turnaround time, which is used to measure the efficiency of airline operations. Therefore, to reduce boarding time, it is imperative to reconsider traditional passenger boarding strategies to make them more efficient. In this sense, this study seeks to analyze the impact of different strategies on boarding times using discrete event simulation on an Airbus 320. Seven boarding strategies have been identified and considered in our study, as follows: random, back-to-front, outside-in, reverse pyramid, blocks, Steffen, and modified optimal. The impact of carrying hand luggage and the presence of priority passengers has been considered, as well as the impact of having a continuous arrival of passengers during the boarding process versus having all passengers available at boarding time. In general, simulation results have pointed out that the outside-in and reverse pyramid strategies are the most effective, improving boarding time by up to 15%, when compared to the random strategy. Moreover, the back-to-front strategy, which is generally implemented by airline companies, has been shown to be the most inefficient strategy. Efficient boarding strategies are expected to contribute to the sustainability of air travel by minimizing the turnaround time, improving operational efficiency, and reducing emissions.
Prospective Evaluation of the Public Transport System in the Petrosani Basin
Authors: Mihailescu Sorin
Published: December 2023

Public transport is one of the most important functions of a city, which can have a major impact on the elements that support sustainable development: society, the environment and the economy. In order for residents and tourists of the Petrosani Basin to benefit from a predictable, systematized public transport system with well-established travel times, it is necessary to analyze some current factors and trends regarding public transport in the Petrosani Basin. This prospective study confirms that the use of the public transport system in the Petrosani Basin is decreasing, a decrease mainly associated with the lack of spatial accessibility, comfort and safety for passengers (inappropriate stations, the lack of air conditioning in means of transport, the lack of a modern fare system, the lack of means of information in the stations, etc.) but also with the change in people’s attitudes imposed by the protective measures taken as a result of the coronavirus pandemic. However, it should be noted that the public transport system in the Petrosani Basin is strongly influenced by the geographical characteristics of the Petrosani Basin, by the sharp decrease in the population (a negative natural increase and a reduction in the school population) and by the increase in the number of private cars.

Published: December 2023

Given a decreasing and aging population, there is a growing need to establish convenient public transportation systems that offer a variety of transportation modes seamlessly connected to one another. This study attempts to develop an index to assess the hierarchical diversity of public transportation, drawing an analogy between public transportation networks and ecosystems. By considering both hierarchical (meta-physical) and physical connections among respective modes, which are aspects that have not been addressed in previous studies, this study aims to enhance the spatial resolution of the analysis units in the index. The diversity indices were applied to the northern Osaka area in Japan as the study site. The results show a correlation between the diversity index, population, and public transportation modal share. We then discuss the influence of hierarchical diversity on the sustainability of public transportation systems and regional development.

Authors: Mulders Miriam , Träg Kristian Heinrich
Published: December 2023

Virtual reality (VR) and augmented reality (AR) are emerging technologies with a variety of potential benefits for sustainability education. Here, learning processes such as flow and presence seem to determine the learning experience. Therefore, this paper presents the results of a mixed-methods study investigating a VR- and AR-based learning application on biodiversity developed by greenpeace. A total of 156 students tested the application addressing the Amazon rainforest and rated its efficacy in terms of effects on knowledge, interest, and attitude. Pre- and post-questionnaires as well as focus groups were used to uncover within-subject effects. The study results revealed that flow and presence had a moderating effect on knowledge and that this effect is strongest in learners with little prior knowledge. Presence also showed a moderating effect on one of three attitude measures. In general, the learning application was able to increase knowledge and improve attitude in this sample. The focus groups also revealed that the students engaged with environmental topics even after the experience. They also formed ideas for more environmentally friendly behavioral change. Moreover, the students described the application as impressive, captivating, and realistic. It can be concluded that presence and flow are crucial processes for learning with VR and AR technologies.

Published: December 2023

The use of genetically modified, glyphosate-resistant crops has led to the widespread application of glyphosate-based herbicides (GBHs), making them one of the most widely used herbicide formulations on the market. To enhance the efficacy of the active ingredient, GBHs used in practice often contain other ingredients marked as inert “adjuvants” or “co-formulants”, the toxic properties of which are poorly understood. The objective of this study was to compare the cytotoxic effects of pure glyphosate, three GBHs (Roundup Mega, Fozat 480 and Glyfos) and two co-formulants commonly used in GBHs as assessed via CCK-8 assay, and the extent of their potential oxidative damage as assessed via superoxide dismutase (SOD) assay, in order to reveal the role of adjuvants in the toxicity of the formulations. Our results showed that glyphosate alone did not significantly affect cell viability. In contrast, GBHs and adjuvants induced a pronounced cytotoxic effect from a concentration of 100 μM. SOD activity of cells treated with GBHs or adjuvants was significantly lower compared to cells treated with glyphosate alone. This suggests that the adjuvants in GBHs are responsible for the cytotoxic effects of the formulations through the induction of oxidative stress.
Zeeman Splitting of Torsional Oscillation Frequencies of Magnetars
Authors: Yakovlev Dmitry
Published: December 2023

Magnetars form a special class of neutron stars possessing superstrong magnetic fields and demonstrating power flares triggered by these fields. Observations of such flares reveal the presence of quasi-periodic oscillations (QPOs) at certain frequencies; they are thought to be excited in the flares. QPOs carry potentially important information on magnetar structure, magnetic field, and mechanisms of magnetar activity. We calculate frequencies of torsional (magneto-elastic) oscillations of the magnetar crust treating the magnetic field effects in the first order of perturbation theory. The theory predicts the splitting of non-magnetic oscillation frequencies into Zeeman components. Zeeman splitting of the torsional oscillation spectrum of magnetars was suggested, clearly described and estimated by Shaisultanov and Eichler (2009), but their work has not been given considerable attention. To extend it, we suggest the technique of calculating oscillation frequencies, including Zeeman splitting at not too strong magnetic fields for arbitrary magnetic field configuration. Zeeman splitting enriches the oscillation spectrum and simplifies the theoretical interpretation of observations. We calculate several low-frequency oscillations of magnetars with a pure dipole magnetic field in the crust. The results qualitatively agree with the low-frequency QPOs detected in the hyperflare of SGR 1806–20 and in the giant flare of SGR 1900+14.

Novel swine orthopneumovirus (SOV) infections have been identified in pigs in the USA and some European countries but not in Asian countries, including South Korea, to date. The current study reports the first SOV infections in four domestic pig farms located in four provinces across South Korea. The detection rate of SOV in oral fluid samples using qRT-PCR was 4.4% (14/389), indicating the presence of the virus in pigs at commercial farms in Korea. Two complete genome sequences and one glycoprotein (G) gene sequence were obtained from SOV-positive samples. The complete genome analysis of KSOV-2201 and KSOV-2202 strains showed 98.2 and 95.4% homologies with a previously reported SOV, and the phylogenetic tree exhibited a high correlation with a previously reported SOV strain from the US and a canine pneumovirus (CPnV) strain from China. Based on the genetic analysis of the viral G gene, the murine pneumonia virus (MPV)-like orthopneumoviruses (MLOVs) were divided into two genogroups (G1 and G2). Seventeen CPnVs and two feline pneumoviruses were grouped into G1, while the Korean SOV strains identified in this study were grouped into G2 along with one SOV and two CPnVs. These results will contribute to expanding our understanding of the geographical distribution and genetic characteristics of the novel SOV in the global pig population.

Little is known about the long-term durability of the induced immune response in subjects with obesity, particularly in those with an abdominal distribution of adipose tissue. We evaluated SARS-CoV-2-specific antibody responses after BNT162b2 vaccine booster dose, comparing individuals with and without abdominal obesity (AO), discerning between individuals previously infected or not. IgG-TrimericS were measured in 511 subjects at baseline, on the 21st day after vaccine dose 1, and at 1, 3, 6, and 9 months from dose 2, and at 1 and 3 months following the booster dose. To detect SARS-CoV-2 infection, nucleocapsid antibodies were measured at baseline and at the end of the study. Multivariable linear regression evaluated the three-month difference in the absolute variation in IgG-TrimericS levels from booster dose, showing AO and SARS-CoV-2 infection status interactions (p = 0.016). Regardless of possible confounding factors and IgG-TrimericS levels at the booster dose, AO is associated with a higher absolute change in IgG-TrimericS in prior infected individuals (p = 0.0125). In the same regression model, no interaction is highlighted using BMI (p = 0.418). The robust response in the development of antibodies after booster dose, observed in people with AO and previous infection, may support the recommendations to administer a booster dose in this population group.

Background: The WHO recommended the use of the RTS,S/AS01 malaria vaccine (RTS,S) based on a pilot evaluation in routine use in Ghana, Kenya, and Malawi. A longitudinal qualitative study was conducted to examine facilitators and barriers to uptake of a 4-dose RTS,S schedule. Methods: A cohort of 198 caregivers of RTS,S-eligible children from communities where RTS,S was provided through the pilot were interviewed three times over a ≈22-month, 4-dose schedule. The interviews examined caregiver perceptions and behaviors. Children’s vaccination history was obtained to determine dose uptake. Results: 162 caregivers remained at round 3 (R3); vaccination history was available for 152/162 children. Despite early rumors/fears, the uptake of initial doses was high, driven by vaccine trust. Fears dissipated by R2, replaced with an enthusiasm for RTS,S as caregivers perceived its safety and less frequent and severe malaria. By R3, 98/152 children had received four doses; 34 three doses; 9 one or two doses; and 11 zero doses. The health system and information barriers were important across all under-dose cases. Fears about AEFIs/safety were important in zero-, one-, and two-dose cases. Competing life/livelihood demands and complacency were found in three-dose cases. Regardless of the doses received, caregivers had positive attitudes towards RTS,S by R3. Conclusions: Findings from our study will help countries newly introducing the vaccine to anticipate and preempt reasons for delayed acceptance and missed RTS,S doses.

Fragility Analysis for Water-Retaining Structures Resting on Spatially Random Soil
Authors: Cho Sung-Eun
Published: December 2023

The maintenance of water-retaining structures involves evaluating their performance against current and future operating water levels. Fragility curves are commonly used for this purpose, as they indicate the conditional probability of failure for various load conditions and accurately characterize a structure’s performance. Monte Carlo simulation (MCS) can be used to determine the fragility curve of water-retaining structures by calculating the probability of failure as the water level changes. However, performing repetitive MCS involves extensive calculations, thus making it inefficient for practical applications. Therefore, it is essential to develop efficient methods that require a minimum number of MCS runs to estimate the fragility curve. This study proposed two methods to estimate the fragility curves of water-retaining structures, thereby allowing for the assessment of failure probabilities related to important quantities such as the steady-state seepage rate, exit gradient, and uplift force, which make them suitable for practical applications. The fragility curves obtained using the proposed methods are valuable for risk assessment, design, and decision-making purposes, as they offer information to evaluate the performance of the water-retaining structure under various water level conditions.
Conflicts in Adolescence and Their Association with Closeness: Results of a Multi-Perspective Study from Germany
Authors: Öztürk Yasmin , Eichhorn Thomas , Zerle-Elsäßer Claudia
Published: December 2023

Adolescence is marked by rapid biological and psychosocial changes that profoundly impact parent–child communication in order to reorganize responsibilities and move toward a more egalitarian relationship. Therefore, our primary objective in the present study was to explore the influence of changing conflict frequency and intensity on the perceived level of closeness between parents and adolescents, considering the perspectives of both parties involved. Using 10-wave longitudinal data with measures of parents (n = 17,005) and their children (n = 15,841) aged seven to 16 from the German Panel “Analysis of Intimate Relationships and Family Dynamics” (pairfam), the present study used fixed-effects models to address the research goal. The findings indicate that, for parents and adolescents, an increase in both conflict frequency and intensity corresponds to a more pronounced decline in closeness. Higher levels of initial closeness when the participants entered the survey resulted in milder decreases in closeness when conflict intensity was higher, a pattern observed for both parents and adolescents. Regarding conflict frequency, no impact of initial closeness was discerned among parents, while an opposing effect was found among adolescents. These findings shed light on changes in parent–child communication during the transition from early to middle adolescence, underscoring the need for further exploration of the closeness–conflict association.

In the past few decades, the textile industry in Türkiye has been developing rapidly with raw materials, industrialization, and employment opportunities. The use of complex machine processes in mass production methods in the textile industry, creates working conditions with high
noise levels are created. In this paper, indoor acoustic performance in the textile industry was discussed and the interpretation of the acoustic environment by the employees was analyzed. The textile industry facility in Malatya, Türkiye was examined as a case study. The employees' daily
noise exposure levels (LEX,8h) and sound pressure levels were measured. Additionally, Weinstein's Noise Sensitivity Scale (WNSS) and noise annoyance structured questionnaire were applied to the employees. The highest noise exposure level was 92,8 dB, and the lowest noise exposure level was
86,9 dB. In conclusion, the statistical relationship between noise sensitivity and noise annoyance of employees with the demographic properties was examined and the noise annoyances were analyzed in detail. It was found that there was a significant and positive relationship between the noise
sensitivity and noise annoyance of the employees (r = 0,523, p = 0,000 < 0,05). Suggestions have been developed to improve indoor acoustic performance and reduce noise in the textile industry.
Mechanism of Tire / Road Noise Emission and Reduction Technology
Authors: Saito Yoshinori
Published: December 2023

The significant noise reduction has been brought by recent electrification of power train of vehicles. More concern about impact on the health due to the environmental noise, especially road traffic noise, requires further reduction of tire / road noise emission caused by the contact
between the tire and road surface. The tire / road noise emission mechanism can be described by three different systems such as the excitation, the response, and the propagation. The excitation is composed of the road excitation, the tread excitation, the air-pumping and the friction. The
tire structural response and the acoustic response in the void formed inside contact patch are respectively excited by those sources. The recent technology development in numerical analysis and test methods allow us to investigate the detailed behavior of tire in various rolling condition.
The present article gives progresses on the mechanism understanding of tire / road noise emission and some reduction technologies.

Published: December 2023

The present work aims to utilize two different waste carbonaceous fillers, i.e., recycled carbon black (RCB) (industrial waste) and recycled graphite (RGP) (Battery waste), for the fabrication of vibration damping composites. Three types of composites were prepared, i.e., Neat NR, NR/RCB20,
and NR/RGP20, using natural rubber (NR) matrix according to the standard ASTM D 3182-21a. The physical and mechanical properties of developed composites were investigated as per the standard ASTM D792-20 and ASTM D412-16. Moreover, the interfacial damping mechanism between polymer matrix,
RCB, and RGP fillers was studied by determining vibration-damping properties as per standard ASTM E756-05. Furthermore, the influence of different parameters, such as particle size, carbon content, and surface area, of carbonaceous fillers on the resulting damping characteristics of developed
composites was investigated through SEM, CHNS, and BET analysis. The result suggests that with the addition of 20 phr of RCB and RGP in the polymer matrix, the density of NR/RCB20 and NR/RGP20 composites were increased by ~ 7.08% and ~ 14.68%, respectively. Moreover, the mechanical and vibration
damping properties of NR/RCB20 and NR/RGP20 composites show better performance than Neat NR composite.
Exploring deep learning architectures for urban sound classification
Authors: Borin Marcel , Masiero Bruno , Monteiro Carolina
Published: December 2023

Urban sound monitoring is an essential part of city planning as it helps to understand the acoustic environment and its impact on citizens. Machine learning is a valuable tool in this field, providing important insights into the city's soundscape and supporting informed decision making,
which can be useful for implementing noise mitigation measures and ensuring regulation compliance using sound source identification. Low-cost acoustic sensors have proven to be a highly effective way to acquire input data, offering scalable and widespread acoustical coverage of a city. The
objective of this project is to improve upon existing sound classification models by comparing the performance of deep learning architectures such as Convolutional Neural Networks (CNNs), Long Short-Term Memory (LSTM) networks, and the hybrid Recurrent Convolutional Neural Network (RCNN) approach.
This study will also explore more sophisticated architectures, which incorporate dual channel feature extraction and temporal-frequency attention mechanisms (TFCNN). By evaluating the effectiveness of these models, the project aims to drive the field forward and support the development of
smart, sustainable cities. The goal is to provide decision-makers with the insights and tools they need to create a better acoustic environment for city dwellers.

Authors: Iannace Gino , Amadasi Giovanni , Trematerra Amelia , Bevilacqua Antonella
Published: December 2023

Noise and vibration from trains and tramlines pass-by's within urban context are always cause of complaints by citizens, due to the high level of annoyance especially when the vehicle activity involves night-time periods. This paper deals with the acoustic design of mini screens composed
of metamaterials to be placed at the edge of railways for shielding the noise from trains crossing urban areas. Acoustic measurements have been undertaken by using the beamforming approach along with linear array microphones in order to identify whether the noise is the most originated. It
has been identified that the friction between wheels and railways is the source of noise other than the weight of carriage that moderately impact the results. The measured results show that the noise source is located in the trolley area, precisely at a level higher than the rolling rails.
This conclusion has been investigated by a reverse engineering method on microphones array data and based on diffraction theory. Moreover, it has been considered the variability of noise emission from convoys in transit by applying normalisation of the energy contents through time-frequency
analysis (wavelet). Further studies have been focused on the location and geometry of the mini screens based on the best acoustic performance, which can achieve a reduction of 6-8 dB for distance of 10 m and 100 m across the horizontal plane, and up to 9 dB for distance of 40 m on vertical
plane.

Published: December 2023

Key Points

Natural killer cells infiltrate the kidney after cardiac arrest and medial renal fibrosis

Granzyme A is produced by natural killer cells and causes mesenchymal cell expansion and fibrosis in type 1 cardiorenal syndrome

Background

The AKI to CKD transition presents an opportunity for intervention to prevent CKD. Our laboratory developed a novel murine model of AKI-CKD transition and cardiac arrest/cardiopulmonary resuscitation (CA/CPR), in which all animals develop CKD at 7 weeks. The purpose of this study was to identify potential immune drivers of fibrosis after CA/CPR.

Methods

Cardiac arrest was induced by potassium chloride, and mice were resuscitated with chest compressions and epinephrine. The kidney immune landscape after CA/CPR was profiled using 11-color flow cytometry analysis and immunofluorescence. Immune cell-derived mediators of fibrosis were identified by analyzing data from three previously published single-cell or single-nuclear RNA sequencing studies. NRK49F fibroblasts were treated with granzyme A (GzA) in vitro, and then cell proliferation was quantified using 5-ethynyl-2′-deoxyuridine. GzA was pharmacologically inhibited both in vitro and in vivo.

Results

Immune cells infiltrated the kidney after CA/CPR, consisting primarily of innate immune cells, including monocytes/macrophages, neutrophils, and natural killer (NK) cells. NK cell infiltration immediately preceded mesenchymal cell expansion, which occurred starting 7 days after CA/CPR. Immune cells colocalized with mesenchymal cells, accumulating in the areas of fibrosis. Analysis of previously published single-cell or single-nuclear RNA sequencing data revealed GzA as a potential mediator of immune to mesenchymal communication. GzA administration to fibroblasts in vitro induced cell growth and proliferation. Pharmacologic blockade of GzA signaling in vivo attenuated fibrosis and improved renal function after CA/CPR.

Conclusions

Renal inflammation occurs during cardiorenal syndrome, which correlates with mesenchymal cell expansion. GzA, produced by NK cells, presents a novel therapeutic target to prevent the transition to CKD after AKI.

Published: December 2023

Since the outbreak of the COVID-19 pandemic, a significant share of workers has been involved in some form of telework. Remote work arrangements are currently affecting a wide range of firms and industries. However, its usage is significantly lower among small and medium companies. So far, the study of the attitudes and motivations of business owners and managers of small companies for promoting this new modality of work organization has been poorly addressed. This research aims to reduce this shortage by implementing an empirical analysis based on a sample of managers in small and medium-sized (SMEs) European companies. Our findings reveal the critical influence of organizational culture, the achievement of competencies related to the capacity of team building using digital tools and the subjective perceptions of usefulness on the decision to implement telework. It also provides insight into the most important determinant factors for reshaping work organization in European SMEs. Considering the incipient regulatory framework for flexible work arrangements, the results have practical implications for in-company training strategies and the policies to foster telework implementation in SMEs.

Published: December 2023

For this study, a survey targeting 420 students from a 4-year university in Cheonbuk Province. The specific findings of this study are as follows.
First, the research model devised to examine the structural relationships among e-Learning readiness, presence(teaching presence, cognitive presence) and learning performance(perceived achievement, learning satisfaction, intention to persist in learning) perceived by the university students was fit. This means there are significant structural relationships among e-Learning readiness, presence(teaching presence, cognitive presence) and learning performance(perceived achievement, learning satisfaction, intention to persist in learning). Second, when analyzing the direct effects of the variables, the significant direct effects were found between 1) e-Learning readiness and learning satisfaction, 2) e-Learning readiness and intention to persist in learning, 3) e-Learning readiness and presence(teaching presence, cognitive presence), 4) teaching presence and learning performance(perceived achievement, learning satisfaction, intention to persist in learning), 5) teaching presence and cognitive presence, and 6) cognitive presence and learning performance(perceived achievement, learning satisfaction, intention to persist in learning), except for the direct effects on e-Learning readiness and perceived achievement. Third, when analyzing the indirect effects of the variables, there were significant mediating effects of teaching presence in the relationship between 1) e-Learning readiness and learning performance(perceived achievement, learning satisfaction, intention to persist in learning), and of cognitive presence in the relationship between 2) e-Learning readiness and learning performance(perceived achievement, learning satisfaction, intention to persist in learning). Also, the double-mediating effects of teaching presence and cognitive presence were significant in the relationship between e-Learning readiness and learning performance(perceived achievement, learning satisfaction, intention to persist in learning).
This study verified the causal relationships of individual variables, which are relevant to high learning performance in university e-Learning and suggested a methodology to enhance the level of learning performance. In conclusion, the study suggests the need for an instructional design to reinforce e-Learning readiness for enhancing learning performance and for a consideration of teaching presence and cognitive presence factors for an instructional design.

The purpose of this study is to develop local community-level indicators that can monitor the capabilities of global citizens to measure the effectiveness of global citizenship education for adults amid the spread of global citizenship education. It followed the distinction of cognitive, social and emotional, and behavioral areas, which are the core competencies of global citizens presented by UNESCO. The categories were selected after reflecting the main conceptual words derived through prior research analysis and the preliminary survey results for related parties, and considering the major conceptual words necessary for Y-gu, Incheon. After that, an expert Delphi survey was conducted twice to develop indicators. The results of the study are as follows. A total of 46 indicators were developed, including 3 categories, 14 conceptual elements, and 17 questions in the cognitive domain, 3 categories, 13 concept elements, 15 questions in the social and emotional domain, and 3 categories, 10 concept elements, and 14 questions in the behavioral domain. Through this study, it was confirmed that global citizenship and local citizenship should be recognized from an integrated perspective, and that global problems should be viewed in connection with local daily lives. This study is meaningful in that it presented examples that can be appropriately used in other regions where global citizenship education is being conducted.

Published: December 2023

Maintaining a certain level of rice production must coincide with maintaining soil fertility, reducing pollution to the environment, and reducing water consumption. A field experiment was carried out during the 2020 summer growing season in a spot of Al-Issa county-Abbasiya district in the province of Najaf, in order to study the effect of different levels of irrigation and organic fertilizers on the growth, yield and components of the local rice variety Jasmine. The experimental plants were planted on June 17, according to the rice intensification system (SRI) method, by seedling method, at distances of 25 cm between seedlings and lines, with one seedling in the hole. Weeds were removed by hand three times. It was designed as a factorial experiment using a randomized complete block design (RCBD) with three replicates, where the irrigation levels (daily, 3 or 7 days irrigation intervals) as the main factor, while the organic fertilizers at two levels (10 and 5 ton.hˉ¹) were the secondary factor. The results showed that irrigation at 3 days intervals in clay soil mixed with the use of 10 ton.h-1 of organic fertilizers in SRI gave the highest rates of growth characteristics and yield components of Jasmine rice. In the case of irrigation and soil conditions in the study site, SRI is recommended to reduce water consumption and maintain an acceptable level of soil fertility, taking into account maintaining a level of production.

The land cover classification in urban areas is described in this research work. The use of hyperspectral image analysis is growing in popularity because it performs better than conventional machine learning techniques. Hypercubes, a type of three-dimensional dataset with two spatial dimensions and one spectral dimension, make up the Hyperspectral imaging (HSI). An overview of HSI's uses in remote sensing applications and the methods for classifying it are given in this research. In the field of HSI, numerous experiments are conducted with various deep learning methods for analysis and classification. The main components of this research is convolutional neural network (CNN)and long short-term memory (LSTM) that shows to be more effective than alternative models. In this case, spectral and spatial features are extracted using CNN and LSTM, respectively, and the results are then classified using support vector machines (SVM). The datasets utilized in this study were gathered using a ROSIS sensor/spectrometer at Pavia University and Indian Pines.
