Introduction. Artificial neural networks are widely utilized in medical fields, such as dentistry, molecular genetics, immunology, cardiology, and others. Forensic medicine is no exception, as artificial neural networks are also beginning to find applications in this field. The aim of this study was to demonstrate the potential for predicting human anthropometric parameters using dermatoglyphic parameters, which could enhance the method of dermatoglyphic identification. Materials and methods. We analyzed dermatoglyphs of the hands and feet from 567 individuals aged 18 to 59 years, with no genetic or endocrine disorders and no musculoskeletal problems. Results and discussion. The outcome of our work resulted in the development of the "Dermatoglyphics For Prediction (DFP)" program [Author's Certificate No. 74561. Computer program "Forensic Medical Identification Program using Artificial Neural Networks" Registration date: 07.11.2017]. This software device, after appropriate training, enables the prediction of an individual's ethnic-territorial affiliation and the presence of specific anthropometric parameters using such input data as dermatoglyphs of the hands and feet. Conclusions. The increasing needs of the Ukrainian community for the identification of unknown individuals, given the geopolitical situation related to Russian invasion in Ukraine (the constant threat of ballistic missile attacks and unmanned aerial vehicles across the entire territory of Ukraine, which could lead to mass casualties), justify the relevance and the search for innovative approaches to dermatoglyphic identification expertise, utilizing state-of-the-art technologies, particularly neural network-based prediction of anthropometric parameters, sex, and ethnic-territorial affiliation of an unknown person, using input parameters such as dermatoglyphs of the hands and feet, with the aim of enhancing the evidentiary value of identification expertise. This software device, after appropriate training, allows for the prediction of ethnic-territorial affiliation and the presence of specific anthropometric parameters in the examined individual using such input data as dermatoglyphs of the hands and feet.

The COVID-19, a disease caused by the SARS-Cov2 virus, had its first cases recorded at the end of 2019. Since then, a health crisis has set in on the planet. According to the World Health Organization the COVID-19 pandemic has already caused the death of more than 6 million people and caused the routines of the entire population to change completely, or partially. In the educational field, with social distancing being one of the measures used to reduce the number of cases, classes, activities, tests and most of the activities related to education started to take place remotely. As a result, the discipline of science, which requires practice, investigation and experimentation for the content to be better understood by students, has become considerably more difficult to experience with social distance. As a number of sudden changes have emerged, so too have new challenges, which teachers need to manage. In this context, the present research aimed to ascertain how the teaching-learning process is being carried out and the challenges faced by the target audience the learners in the subject of Science in the context of the pandemic of COVID-19. The research targeted primary school students aged between 11-15 years old living in a rural community in the municipality of Salgueiro/PE, Brazil. It was found that students' learning and mindset were negatively affected by remote teaching and social isolation during the pandemic. The most suitable didactic tools for the target audience of the research were identified, and better results regarding learning would have been obtained if complementary activities that stimulated empathy and care of the students' mental health were also used.

Published: December 2023

Accurate hydrological data is crucial for understanding streamflow changes and predicting extreme events in river basins. By utilising remotely sensed soil moisture products, the estimation of soil moisture distribution at the basin scale in hydrological modelling becomes feasible, addressing practical challenges. This study investigates the integration of remotely sensed soil moisture estimates to enhance the accuracy of hydrological model simulations in the upper Peradeniya catchment, Sri Lanka. A hydrological model (ABCD model) was developed for the catchment area. Soil moisture data from NASA's soil moisture active passive (SMAP L4) were integrated with the model's estimations to improve river flow simulations. The study reveals that the integration of SMAP L4 did not significantly enhance accuracy. However, notable differences in calibrated parameters emerged, highlighting the importance of incorporating multiple inputs for calibration. These findings demonstrate the potential of remotely sensed soil moisture in enhancing hydrological model simulations. Incorporating remotely sensed soil moisture can contribute to more reliable predictions and management of water resources in river basins, aiding in sustainable development and climate change adaptation.

Flooding is one of the most frequently encountered natural disasters globally. Frequent severe flood occurrences in Rathnapura city, Sri Lanka caused damages to both human lives and infrastructures. Data-driven models have been showing their ability of flood susceptibility mapping (FSM) in data-scare regions as an alternative to traditional hydrological models, but they are not widely used by stakeholders due to their black-box nature. This research suggests utilising the shapley additive explanation (SHAP) method to interpret the results generated by the CatBoost machine learning model and to assess the influence of different variables on flood susceptibility mapping. A flood inventory (445 flooded locations) and thirteen flood conditioning factors were used to implement the model and results were validated using the area under curve (AUC) method, which showed a success rate and prediction rate of 93.1% and 92.5%, respectively. SHAP plots indicated that the regions with lower elevations and topographic roughness values, gentler slopes, closer proximity to rivers, and moderate rainfall are more susceptible to flooding. According to the results obtained, we suggest incorporating SHAP-based datadriven models in forthcoming studies on FSM to enhance the interpretations of model outcomes.

Graphene, a remarkable two-dimensional carbon allotrope characterized by a hexagonally arranged carbon lattice, has garnered significant attention due to its extraordinary properties and diverse range of applications. For the synthesis of graphene, multiple methods are available. In this research, we opted for the electrochemical exfoliation method due to its simplicity, scalability, and environmentally friendly attributes. This methodology follows a top-down paradigm, whereby graphene is derived from graphite. The experimental configuration involved the construction of an electrolytic cell, employing carbon electrodes fabricated from compacted graphite powder, with a 0.1M Na2SO4 solution serving as the electrolyte. By systematically varying the voltage, current, and spatial separation between the anode and cathode, five experimental trials were conducted. Subsequently, the electrolyte underwent filtration, and the resultant residue underwent a drying process. Morphological observation of the synthesized graphene samples was facilitated using scanning electron microscopy (SEM). Furthermore, the confirmation of graphene sample purity was achieved through energy dispersive x-ray spectroscopy (EDS). The x-ray diffraction (XRD) analysis revealed a distinct diffraction peak at 2θ=26.4°, corresponding to the (002) plane. Additionally, the absorption peak of graphene was identified at 230 nm. Our findings strongly suggest that electrochemical exfoliation represents a promising avenue for the synthesis of grapheme utilizing Sri Lankan graphite. However, further investigations are imperative to refine and optimise this method for the large-scale production of graphene.

This study examines the crucial role that feed size plays in the fine grinding of dolomite obtained from Sri Lanka's Naulla deposit. The study is carried out at Metal Mix Pvt. Ltd. Galpatha site, a commercial facility that prepares dolomite for use in a variety of industries. By identifying the most efficient feed size range that improves comminution efficiency while attaining the desired particle size distribution, the main goal is to optimise the dolomite crushing unit, in particular the autogenous mill. The research process includes in-depth field tests and laboratory examinations. The effect of different feed size ranges on the grinding process is assessed by on-site studies. Analyses of the particle size distribution are performed based on the output of the autogenous mill to evaluate how well it performs with various feed sizes. The outcomes show that there is a distinct relationship between feed size and the effectiveness of fine grinding. According to the study, limiting feed size ranges from 1.5 to 4 inches which greatly raises crushability, cuts down on energy waste, and optimizes the grindability. The dolomite processing industry, where energy-efficient comminution is of utmost importance will be benefitted out of the findings of this study.

Heavy metals (HM) can be defined as metallic elements that are greater than 40 in atomic weight and above 5 g/cm3 in specific gravity and cause abnormal effects on the biota at low concentrations. This study aimed to assess the levels of HM contamination in soils and unpolished rice grains (Oryza sativa) at three separated paddy cultivation fields in Anuradhapura, Gampaha, and Jaffna over one consecutive season. The concentrations of arsenic (As), cadmium (Cd), and lead (Pb) were detected using inductively coupled plasma mass spectrometry (ICP-MS). According to the results, HM concentrations of As and Pb in the soil for all studied fields were below the maximum permissible limits (MPL) set by the World Health Organization/Food and Agriculture Organization (WHO/FAO). However, Pb content in rice grains was high in all stations relative to the MPL for crops given by WHO/FAO. The results revealed that Cd has exceeded MPL of both soil and grains in the Jaffna paddy field according to the WHO/FAO guidelines and Cd has a high transfer factor (TF>0.27) from soil to grain among all concerned agricultural lands. Other heavy metals have lower TF values (0.001 to 0.131). Regarding the contamination factor, As, Cd and Pb showed a moderate level of contamination severity over three regions.

Published: December 2023

Lanka has been a well-known natural vein graphite supplier to the world since 1820. This reputation is mainly due to its extremely high purity, the purity being above 99% carbon as in-situ status and no other country in the world has vein graphite deposits for commercial mining now. Vein graphite is mined at Kahatagaha, Bogala, Ragedara and also from a few smaller underground mines in Sri Lanka. For decades, the Kahatagaha graphite mine has been practising the ‘open stope mining method’ and this method itself does not require extensive mine support because high strength of host rock inside the mine. It can be thought that the behaviour of graphite veins especially inclined in nature and stable host rock could be the main factors to select above mentioned mining method. But, this mining method causes many practical issues now so that mine production, miners` safety and underground work supervision are badly affected. This research includes the study of the current mining method adopted at Kahatagaha graphite mine and its suitability compared with other mining methods used for narrow vein mining and proposing a mining method which is more suitable, safer, and more economical compared to the current practising method.

The demand for sand is increasing due to construction activities. River sand scarcity causes illegal mining and environmental damage. The construction industry faces negative impacts if river sand becomes unavailable or scarce. Therefore, finding a suitable substitute is essential for the sustainability of the construction industry as well as preventing further degradation of the river ecosystem. Quarry dust, a byproduct of crushing is studied as a potential substitute. The investigation assessed the feasibility of using quarry dust as a partial replacement for river sand in wall plaster. Quarry dust was utilised to achieve the desired particle size distribution equivalent to that of sand. Five types of cement-sand-quarry dust wall plaster mortars were made. The volume ratios between sand and quarry dust were kept at 1:0, 4:1, 2:1, 3:2, and 0:1 while maintaining a constant cement amount for all mixtures. Then the strength and durability of plastering mortar were examined using destructive and non-destructive test methods. The obtained results were compared with wall plaster made from 100% sand. Results demonstrated that the optimal combination of strength, durability, and workability was achieved when using a sand-to-quarry dust ratio of 2:1. Also, this mixture reduced plastering mortar cost by 6%, recommending replacing 1/3 of the sand with resembled quarry dust for plastering mortar.

Coastal erosion is a substantial natural hazard that is affecting both the environment and human communities globally. Sri Lanka's coastline is about 1600 kilometres, with rich biodiversity and resources, and faces growing coastal erosion, notably in the southern coastal region especially in the Matara District. Therefore, understanding the causes and effects of coastal erosion is essential. This study aims to evaluate shoreline changes from 2000 to 2020 (Weligama to Dikwella) and involves three stages such as mapping shoreline changes using satellite data (Landsat) a digital shoreline analysis system (DSAS), statistical analysis for shoreline changes rates over 20 years, identifying interplay between factors. DSAS measures shoreline changes using baseline approaches and results are presented for both northeast monsoon (NEM) and southwest monsoon (SWM) seasons. NEM shows coastal accretion in Matara due to sediment transportation, while SWM reveals erosion in Devinuwara through strong waves and sediment movement. Sea level rise, rainfall, and river flow correlations influence erosion patterns. Overall, this study emphasizes the use of advanced technology to understand and monitor coastal erosion, help decision-making and develop effective strategies for protecting coastlines.

Salicylic acid-nicotinamide was used as a prediction model in the hydrogen bond interactions dominating a cocrystal structure. The combined conformation of the two molecules was analyzed at the B3LYP-D3BJ and WB97M-D3BJ theoretical level. The existing hydrogen bond dimer conformations were compared with putative conformations to determine the bond energy and stability. Some parameters were assessed for predictive descriptors, such as geometric parameters, total energy, interaction energy, single hydrogen bond energy, HOMO-LUMO gap, Laplacian Bond Order, and Natural Bond Orbital. An existing conformation, SACNIC1, produced intermolecular hydrogen bond energy which was quite higher than the other conformations, including the pure homomolecular conformations of either salicylic acid or nicotinamide. The cocrystal packing formation seems to be initiated with SACNIC1 as the basic structure conformation. Furthermore, the presence of the strongest intermolecular hydrogen bond energy in SACNIC1 suggests its potential utility as a predictive descriptor.

Teorija uma: pregled suvremenih empirijskih rezultata i glavnih teorijskih objašnjenja
Authors: Legg Edward William
Published: December 2023

Teorija uma je sposobnost pripisivanja mentalnih stanja drugima. Do prije otprilike 20 godina empirijska istraživanja upućivala su na to da je teorija uma kognitivno zahtjevna sposobnost koja se razvija oko četvrte godine života. Međutim, sve veći broj istraživanja koja koriste zadatke koji ne zahtijevaju verbalne odgovore upućuje na to da sposobnost koja nalikuje na teoriju uma postoji i izvan kognitivne kontrole te da je pokazuju već i djeca stara devet mjeseci. Ovaj pregledni rad predstavit će tri glavna tipa teorija koje pokušavaju objasniti te novije empirijske rezultate i raspraviti o njima. Nadalje, u radu će biti istaknuti empirijski nalazi koji idu u prilog svakoj od tih teorija ili je opovrgavaju. Iako postoje prijedlozi za kritične eksperimente koji bi trebali moći napraviti razliku između teorija, trenutačno ti prijedlozi još nisu dovoljno korisni za te svrhe jer se podatci koji bi se mogli dobiti takvim eksperimentima mogu u različitim teorijama različito interpretirati. Stoga je važno da se budući rad o teoriji uma fokusira na uklanjanje dvosmislenosti u predviđanjima i interpretacijama svake od teorija.
Creativity and the Simon Task Performance
Authors: Milas Patrk Maša , Šimunić Ana
Published: December 2023

The aim of this study was to examine performance in the Simon task regarding individual differences in creative behavior measured by The Inventory of Creative Activities and Achievements (ICAA; Diedrich et al., 2018). The study included 105 students and 57 younger working-age individuals (from 19 to 36 years of age). Three-way analyses of variance were carried out on the reaction time in the Simon task given the congruence of the previous and current trials and below/above average results on creative activities and achievements scales. The reaction time in the Simon task was on average shorter in congruent than in incongruent trials (the Simon effect), as well as in the trials preceded by congruent than in those preceded by incongruent trials. The Simon effect was only present in trials preceded by a congruent trial, while reaction times in the trials preceded by incongruent trials were shorter in incongruent than in congruent trials (the Gratton effect). However, neither the Simon nor the Gratton effect were more pronounced within more or less creative participants, but the participants with an above average result on the scale of creative activities reacted on average more slowly than individuals with below the average score. The correlations between the scores on the creativity measures and the different reaction times and indices of the Simon and Gratton effect were not significant. The expected effects related to the Simon task have been obtained in this study, but further research is needed to try to replicate the findings regarding the flexibility of inhibitory control measured by performance in the Simon task and creative behavior.
Dendritic Integration Theory as a Cellular Bridge for the Current Major Consciousness Theories
Authors: Čorlukić Mirko , Krpan Jelena , Stojanović Marta
Published: December 2023

Consciousness is often described as the final frontier in science, tackled from multiple disciplines including philosophy, neuroscience, and computer science. Consciousness is most commonly defined as what exists from a first-person perspective, as the feeling of what it is like to be something, as well as through neuronal mechanisms that generate and support this phenomenology. Countless theories on consciousness have emerged to try to elucidate this complicated phenomenon. In our review, we aim to examine the three dominant theories of consciousness - Global Neuronal Workspace Theory (GNWT), Recurrent Processing Theory (RPT), Higher-order Theory (HOT) - and the Dendritic Integration Theory (DIT) as a newer, less prominent, theory that focuses on the cellular basis of consciousness. We propose that DIT may complement the postulations of the other three theories through its cellular approach that bridges state and content consciousness. Finally, we discuss the future of consciousness research more generally.

Published: December 2023

Мета статті – визначити шляхи становлення й проаналізувати особливості виконавської практики тріо бандуристок «Купава» як яскравого представника ансамблевого виконавства Слобідської України кінця ХХ – першої третини ХХI ст.
Результати дослідження. Визначено шляхи становлення та остаточного формування мистецького колективу; особливості концертної діяльності, які знайшли вираження в підході до підбору репертуару, застосуванні мелодекламаційних, речитативних та театралізованих елементів, поєднанні бандурної гри з іншими струнними та духовими інструментами, що є нетиповим для звучання традиційного ансамблю бандуристів межі XX–XXI ст. Акцентовано увагу на використанні естрадного аранжування як окремого супроводу, так і в поєднанні з бандурним, що демонструє виконавську свободу учасниць колективу та прагнення розширити стильові та творчі «кордони». Проаналізовано жанрові особливості концертної програми колективу, які полягають у достатньо різноманітній палітрі – від пісень ритуально-обрядового характеру та обробок українських народних пісень до вишуканих творів романсового характеру. Також відзначено новаторські підходи у виконавській практиці, зокрема в використанні підставок під інструменти.
Наукова новизна полягає в комплексному теоретичному аналізі творчої діяльності тріо бандуристок «Купава», особливостей мистецького життя та виконавських підходів, оскільки в науковій літературі на сучасному етапі відсутня інформація про специфіку практики вищезазначеного колективу.
Висновки. Творча діяльність тріо бандуристок «Купава» відіграє провідну роль у популяризації та розвитку сучасного ансамблевого виконавства Слобідської України. Неповторність стильових та виконавських підходів, сценічний образ, розмаїтість жанрової палітри та багаторічна мистецька практика вирізняє колектив на тлі інших гуртів.

Estas evaluaciones se realizaron con frecuencia semanal durante toda la campaña. Se midió el contenido de clorofila de las 4 hojas por árbol en cada tratamiento; asimismo, se evaluó el rendimiento en cada tratamiento (t ha-1). Los resultados mostraron que los diferentes grados de infestación estudiados: Grado 2 (1-10 ácaros/hoja), Grado 3 (11-25 ácaro/hoja), Grado 4 (26-50 ácaros/hoja) y Grado 5 (mayor a 50 ácaros/hoja) de O. punicae, no influyeron significativamente en los índices de clorofila en las hojas de palto. Además, se determinó que no existe correlación entre los diferentes grados de infestación de O. punicae con el rendimiento de palto. En el presente trabajo no se pudo determinar el umbral de acción para esta plaga y cultivo, ya que los niveles poblacionales estudiados no mostraron un impacto estadísticamente significativo sobre el rendimiento.

BACKGROUND: As physical inactivity and poor sleep quality may impose additional risk for cancer recurrence and overall mortality in postmenopausal breast cancer (PMBC) survivors, it is important to gain insight into the effect of the COVID-19 pandemic on their physical activity (PA) and sleep level. OBJECTIVE: This study aimed to assess the course of their physical activity (PA) and sleep throughout governmental measures against COVID-19 during 12 months of the COVID-19 pandemic. METHODS: PMBC survivors (n = 96) wore an ActiGraph wGT3X-BT for seven consecutive days at 12 and 18 months after diagnosis and additional measurements were taken after onset of the second (partial) COVID-19 lockdown. Longitudinal data was categorized into four timepoints: before onset of COVID-19 (T1), during the initial lockdown (T2), in between initial and second lockdown (T3), and during the second lockdown (T4). General linear mixed effects models assessed differences in moderate-to-vigorous physical activity (MVPA) per day, total minutes of PA per day, average acceleration, intensity gradient, sleep efficiency, and sleep duration over time. RESULTS: Levels of MVPA per day before COVID-19 were low (Median = 20.9 min/day (IQR = 10.8;36.2)), and time spent physically active was most often in light intensity, which remained stable throughout the pandemic. Sleep duration (Median = 442.8 min/night (IQR = 418.3;478.0)) and efficiency (85.9% (IQR = 79.6;88.4)) was sufficient before COVID-19 and showed stability over time. CONCLUSIONS: Low levels of PA with mostly light intensity, and adequate sleep efficiency and duration were observed before COVID in PMBC survivors. This was not further affected by COVID-19 governmental measures.

Published: December 2023

BACKGROUND: Even though cardiovascular stenting is widely used for the treatment of coronary artery disease, information on how it can affect the hematological and hemorheological profile is scarce in the literature. Most of the work on this issue is based on theoretical or computational fluid dynamics models, lacking in-depth in vitro and in vivo experimental verification. OBJECTIVE: This work investigates, in an in vivo setting, the effects of stenting and the implantation time-course on hematological and hemorheological parameters that could potentially compromise the device’s functionality and longevity. METHODS: Custom-made self-expanding nitinol stents were implanted in the common carotid artery of male CD1 mice. Whole blood samples were collected from control (non-stented) and stented animals at 5 and 10 weeks post-implantation. Hematological measurements and blood viscosity, red blood cell aggregation, and deformability were performed using standard techniques. RESULTS: Implant-induced changes were observed in some of the hematological and hemorheological indices. Blood viscosity seems to have been negatively affected by an increased hematocrit and reduced RBC deformability, at 10 weeks post-implantation, despite a slight decrease in RBC aggregation. CONCLUSIONS: Although the alterations observed may be the result of the peri-implant inflammatory response, the physiological consequences due to hemorheological changes need to be further investigated.

Authors: Domin Heather Elaine , Miller Sondria
Published: December 2023

BACKGROUND: Facial recognition technology can significantly benefit society if used ethically. Various private sector, government, and civil society groups have created guidance documents to help guide the ethical use of this technology. OBJECTIVE: The study’s objective was to identify the common themes in these ethical guidance documents and determine the prevalence of those themes. METHODS: A qualitative content analysis of 25 facial recognition technology ethical guidance documents published within the United States or by international groups that included representation from the United States. RESULTS: The results show eight themes within the facial recognition technology ethical guidance documents: privacy, responsibility, accuracy and performance, accountability, transparency, lawful use, fairness, and purpose limitation. The most prevalent themes were privacy and responsibility. CONCLUSIONS: By following common ethical recommendations, industry actors can help address the challenges that may arise when seeking to develop, deploy, and use facial recognition technology. The research findings can inform the current debates regarding the ethical use of this technology and might help further the development of ethical norms within the industry.
Evolutionary feature selection based on hybrid bald eagle search and particle swarm optimization

Published: December 2023

Feature selection is a complicated multi-objective optimization problem with aims at reaching to the best subset of features while remaining a high accuracy in the field of machine learning, which is considered to be a difficult task. In this paper, we design a fitness function to jointly optimize the classification accuracy and the selected features in the linear weighting manner. Then, we propose two hybrid meta-heuristic methods which are the hybrid basic bald eagle search-particle swarm optimization (HBBP) and hybrid chaos-based bald eagle search-particle swarm optimization (HCBP) that alleviate the drawbacks of bald eagle search (BES) by utilizing the advantages of particle swarm optimization (PSO) to efficiently optimize the designed fitness function. Specifically, HBBP is proposed to overcome the disadvantages of the originals (i.e., BES and PSO) and HCBP is proposed to further improve the performance of HBBP. Moreover, a binary optimization is utilized to effectively transfer the solution space from continuous to binary. To evaluate the effectiveness, 17 well-known data sets from the UCI repository are employed as well as a set of well-established algorithms from the literature are adopted to jointly confirm the effectiveness of the proposed methods in terms of fitness value, classification accuracy, computational time and selected features. The results support the superiority of the proposed hybrid methods against the basic optimizers and the comparative algorithms on the most tested data sets.

Published: December 2023

With the continuous expansion of the power grid, the forms of faults are becoming increasingly complex, with a wide range of impacts and long maintenance cycles, posing increasingly severe challenges for power grid operators. In the current power system (PS), due to system limitations, there is a large amount of data, and the current computing system is limited by hardware and computing power, making it difficult to satisfy the requirements of real-time computing, comprehensive analysis, and expansion. This paper analyzed the technical basis of the knowledge graph (KG) of power grid operation and maintenance (O&M), and clarified the key role of model driving in the current large-scale smart grid (SG), which can effectively improve the efficiency and reliability of data processing in the SG. This paper also analyzed the model-driven PG O&M KG platform, and analyzed the role of particle swarm optimization (PSO) algorithm in PG operation and fault maintenance. After applying the PSO algorithm in this article, in the experimental results section, the fault rate of Transformer 5 was 2.1% lower than that of Transformer 4. The knowledge mapping model of grid O&M and the particle swarm algorithm in this paper can significantly reduce the failure rate of the grid, which has wide extension value.

Published: December 2023

To address the problems of underutilization of samples and unstable training for intelligent vehicle training in the Twin Delayed Deep Deterministic Policy Gradient (TD3) algorithm, a TD3 algorithm based on the Composite Prioritized Experience Replay (CPR-TD3) mechanism is proposed. It considers experience immediate reward value and Temporal Difference error (TD-error) based and respectively to construct priorities to rank the samples. Subsequently composite average ranking of the samples to recalculate the priorities for sampling, uses the collected samples to train the target network. Then introduces the minimum lane change distance and the variable headway time distance to improve the reward function. Finally, the improved algorithm is proved to be effective by comparing it with the traditional TD3 on the highway scenario, and the CPR-TD3 algorithm improves the training efficiency of intelligent vehicles.
