Authors: Bykov M. Yu. , Krasnikovskiy V. Ya. , Matveeva N. Yu. , Yaryna E. V.
Published: August 2023

The university environment includes various material and intangible aspects that are subjected now to active changes associated with both the development of information tech-nology and the new needs of young people. Therefore, the attitude of students to their university environment is an actual research topic. The Russian University of Transport (RUT (MIIT)) conducted the online survey of students, during which they were asked an open question regarding university problems and university development. The results showed that the problems associated with communication and mutual understanding, taking into account their opinions and interests, are of the greatest importance for modern students. The wishes of the students to the teaching staff were expressed, from which it is required both the ability to clearly explain the subject, and the presence of an individual and respectful approach to each student. We should not forget about the need of modern students in obtaining practice-oriented modern knowledge and skills, often associated with the need to rejuvenate teaching staff. Attention is paid to aspects related to improving the infrastructure of the university, the educational process. The problems related to the extracurricular scientific and educational life of the university, cultural and sports activities, environmental issues, schedule and mode of classes, work of educational departments are disclosed. The development of political education and patriotism in the university depends on small but effective events and the presence of an organizing groups. The novelty of the obtained data is due to the fact that the answers to an open question always differ from the opinions received in the course of polls with pre-proposed answers, and make it possible to identify hidden trends in public opinion. Respondents, in this case, express what worries them first of all, express the wishes that come to mind first, without prompts. The findings indicate the need to develop a strategy for improving the educational environment of the university, aimed at developing the possibilities of direct communication, increasing informal, understanding interactions.
Chronotope of Engineering and Pedagogical Thinking
Authors: Feoktistov A. V. , Kislov A. G. , Shapko I. V. , Gorodilov V. E.
Published: August 2023

The article is devoted to engineering and pedagogical thinking as a kind of professional thinking that exists due to specific reasons and necessary and sufficient conditions. The “assembly” of these causes and conditions takes place in a certain time-and-place (chronotope), the conceptual reconstruction of which opens the way to overcoming the traditions of haphazard enumerative descriptions of various properties that have developed in the literature and to reaching the construction of the theory of engineering and pedagogical thinking, which, in turn, will help to reasonably update the content and organization of training engineers-teachers, on whom a lot depends in the near technological future of Russia. A review of the characteristics of engineering-pedagogical and related engineering and pedagogical thinking presented in scientific publications is proposed. It shows the need for greater certainty in understanding the nature, foundations, essence and features of heterogeneous engineering and pedagogical thinking. Heterogeneity requires actualization of the potential not only of pedagogy and technical sciences, but also of philosophy, cultural studies, sociology, and psychology. Such actualization shows the heuristic of the communicative interpretation of the nature and essence of thinking. In its light, engineering-pedagogical thinking appears simultaneously as an articulated and unarticulated, discrete and continuous communication of engineers-teachers with students, within which the competencies required by the profession and the impulse developing engineering and technical flair and ingenuity are transmitted, “infecting” (V. Shklovsky2) and charging them, thanks to which communication overcomes the boundaries of the chronotope, gaining continuum features, demonstrating its pulsating situational-suprasituative (corpuscular-wave) dualism. The scientific novelty lies in the justification, by the example of advancing to the theory of engineering and pedagogical thinking, of supplementing the competence approach with consideration of no less significant cultural and subcultural factors, including latent ones, which sometimes manifest themselves in very weak signals about the features of the chronotope of training engineers and technicians by engineers–teachers, not so much by virtue of official regulations as by virtue of singular acts of everyday life communication.

Authors: Farida Yuniar , Siswanto Nurhadi , Vanany Iwan
Published: August 2023

PET (Polyethylene Terephthalate) waste is a crucial problem because of its high consumption as disposable packaging. Even used PET plastic is the most accessible type of plastic to recycle. So, recycling PET plastic waste is a solution to the problem of plastic waste that contributes to environmental safety while providing economic benefits towards a circular economy. In a circular economy, the consumer is the initial entity producing waste to be recycled. So that consumers can act as suppliers in reverse logistics, this study aims to analyze consumer behavior after PET consumption in terms of economic, social, environmental, and regulatory aspects. This study was conducted with a survey on household consumers with residence, education, and income variables. The survey results were presented using descriptive statistics, and the relationship between the variables was tested using the Chi-Square test. The survey results show an association between residence, education, and income variables with post-consumption consumer behavior. This research contributes to determining consumer behavior, leading to increased consumer engagement in the return of waste products in reverse logistics through implementing policies.

Optimization of Closed-Loop Supply Chain Network Design Under Uncertainty: Considering Electric Vehicle Battery Recycling
Authors: Li Peng , Huai Ziting , Jiang Jiaxue
Published: August 2023

In recent years, the market of electric vehicles (EVs) has developed rapidly across the world, and recycling a large number of their spent power batteries has become an urgent challenge today. The resulting closed-loop supply chain (CLSC) have been considerably studied under different aspects. However, there is a lack of research investigating electric vehicle batteries (EVBs) network design under uncertainty. This paper focuses on the issues of quantitative modelling for the network design of a CLSC of used EVBs consisting of power battery manufacturers, EV retailers, collection centers, recycling centers, echelon utilization centers and disposal centers, where power battery manufacturers can remanufacture used EVB products. We investigate a two-stage stochastic mixed-integer programming (SMIP) model to design the network and the model is solved using the Benders Decomposition (BD) method to derive optimal solutions. Numerical experiments show that the SMIP model can effectively hedge against high uncertainty.
A Two-Stage Perception System Calibration Algorithm for Quadruped Robots Using Factor Graph
Authors: Sun Liye , Wu Kanzhi , Liu Yi , Yang Chenguang
Published: August 2023

The accurate calibration of the perception system is one of the key prerequisites for quadruped robots to move safely and robustly in challenging environments. Not only does it provide relative transformations of the sensors w.r.t the robot body but also the time offset between unsynchronized sensors. This paper presents a two-stage spatio-temporal calibration framework for the body-eye calibration of quadruped robots. By attaching one complementary sensor, we first estimate the time offset between the sensor frame and body frame without complicated modifications to the mechanical system. Then we estimate the extrinsic transformation by formulating a hand-eye calibration problem while using the information from the kinematic model and encoder measurements. The extrinsic parameters are finally optimized by minimizing the re-projection error and the kinematics error in a factor graph formulation with a Lie group state representation. The experiments demonstrate that the proposed algorithm produces precise calibration results which guarantee high-accuracy environmental mapping using an RGB-D camera.
Locating and Sizing Public Charging Stations by Considering Spatial-Temporal Electric Taxi Charging Demand
Authors: Wang Xiaochen , Liu Zixi , Qiu Feier , Geng Na
Published: August 2023

Electric taxis (ETs) are the primary public charging station (PCS) users. The inappropriate deployment may lead to inefficient use of PCSs and lengthy queueing of ETs. The fluctuating charging demand of ETs makes it challenging for public charging stations’ location and size decisions. To deal with this problem, this paper develops a new mathematical programming model for locating and sizing public charging stations by considering spatial-temporal ET charging demand. This model considers ET’s actions in detail, including searching for PCSs, queuing, and losing without being served in each period. The objective is to minimize the total cost, including ETs’ transportation cost of driving to PCSs, waiting cost for charging, loss penalty due to limited capacity, and weighted construction expenditure. The decisions are the locations of PCSs, the number of charging piles, and the number of parking spaces. The existing PCSs are considered. Numerical experiments validate the performance of the proposed model. The numerical experiment results show the effectiveness of the proposed model and the significance of taking the spatial-temporal distribution of charging demand into account.

Authors: Ohlig Stefan , Breitkreuz David , Mishra Rakesh , Stegelmeyer Dirk
Published: August 2023

This systematic literature review aims to present the current state of business model research on industrial augmented reality (IAR) and suggest future research areas. Our analysis of 60 previous literature reviews on IAR shows that the business model perspective is missing from these reviews. To address this gap, we conducted a systematic literature review using eight scientific databases in late 2022. Although we aimed for a comprehensive literature search, a total of only 48 augmented reality (AR)-related business model publications were found, of which only six focused on IAR. To present the current state of research, these six publications were analyzed in terms of research purpose and results, the IAR application(s) studied, and the research methodology used. Based on this analysis, we propose future research areas, considering the suggestions for future research and the problems and challenges mentioned in the analyzed publications.

Authors: Perdana Yandra Rahadian , Gusleni Yessi , Listantari Listantari , Juniati Herma
Published: August 2023

During its development, a train should be connected to different transportation modes so consumers have further transshipment nodes, such as airports and bus terminals. Accordingly, the transportation pattern has shifted from a single mode to multimodal, so network connectivity is needed to gain an on-time and reliable transportation process. Practically, the Solo Balapan Train Station, located in Central Java (Indonesia), is one of the central train stations and has a number of essential functions for consumers traveling to other cities or destination areas such as the airport or the bus station. The Solo Balapan Train Station is designed as a multimodal transshipment point in which excellent service is critical to ensure seamless transportation. Thus, performance evaluations are essential to create better transportation services. Contextually, the performance of multimodal transportation services in this study was measured using the Importance-Performance Analysis (IPA) method. The results show that respondents perceive that the quality of the pedestrians’ access, the integrated ticket payment system, and the quality of the supporting facilities are the priorities for service improvement. Also, this study identified that multimodal transportation services at the Solo Balapan Train station were still partially integrated. Consequently, process integration is a necessity to create superior transportation services.

Published: August 2023

The application of the lean manufacturing strategy aims to reduce waste and increase the productivity of the organization in which it is applied; however, in Peru many companies in the metal-mechanical industry do not know how to implement it. The objective of the research is the application of lean manufacturing tools to increase productivity in the manufacturing of washing machines. We implemented 5S to reduce time and route waste, Kanban to standardize production based on demand and lead time, as well as the use of MRPII for its execution. In addition, it was complemented with the Jidoka philosophy to eliminate defective products. The study was carried out in a SMEs company of the metal-mechanic sector that after performing the diagnosis using VSM, productivity (0.1858 washers/H-H), defective products (9.06%) and delivery time compliance (64.67%) of stainless teel washers were identified as the main problems. The imputs found in the data collection were low delivery reliability, high defective rate and low productivity. After the application of Kanban, 5S and Jidoka, an improvement was obtained in the percentage of washers delivered on time to 100% of the orders, a reduction in the percentage of defective products to 3.23%, and an increase in productivity of 5.02%.

Authors: Maghfirah Tuzarra , Kiswanto Gandjar
Published: August 2023

A five-axis milling machine is widely used in the machining of products with complex surfaces and geometries. But there is a problem with the quality of the machined surface and machining efficiency. The inclination angle has a significant impact on surface quality as a parameter in 5-axis milling. Based on complex changes in inclination angles, it is necessary to develop a toolpath using CAM software. In this paper, the incline milling method is developed to evaluate the influence of inclination angle changing rate on surface quality of the machined surface. From the surface roughness and waviness data that will be obtained, the effect of difference in inclination angle changing rate can be used to evaluate the surface roughness and waviness of the machined surface so that the surface roughness and waviness characteristics are in line with the desired production quality. In this method, the inclination angle is formed between the tool and the workpiece, allowing more than one inclination model to be made on one drive surface based on a surface contour. The research results show that the method developed will be very useful in its application to the production process of parts with sculpted surfaces. Using this method, the influence of the inclination angle changing rate on the surface roughness and waviness of the machine surface can be evaluated, and the waviness and roughness of the sculpture surface can be controlled by choosing the right angle of inclination.

In order to improve the braking performance of magnetorheological (MR) brake, a new MR brake with parallel multi-channel structure was developed in this paper. The three layers of axial damping gaps in the MR brake were utilized by using of the magnetic conductivity of the material, and the double excitation coils was also adopted to effectively improve the braking performance. The braking torque and temperature characteristics were analyzed theoretically, and the electromagnetic field and temperature field were simulated and verified. Braking performance and temperature characteristics of the parallel multi-channel MR brake were tested, and the torque, braking time and temperature characteristics of the MR brake were obtained. The test results show that under the condition of constant rotational speed of 700 r/min and applied current of 2 A, the maximum torque can reach 26.25 N⋅m, and the temperature rises from 18.3 °C to 58.01 °C within 20 s. Meanwhile, the braking time is about 1.63 s.
Application of aesthetics in architectural design under the background of big data and artificial intelligence
Authors: Tang Zhong
Published: August 2023

Architectural aesthetics improve the appearance and value of a building/construction structure based on shape, color, rigidity, etc., appealingly. It includes the maximum safety requirements, durability, structural ability, etc. Therefore the aesthetic implementation requires high-level data accumulation and analysis to satisfy the earlier constraints. This article develops a Selective Aesthetic Application Paradigm (SAAP) for meeting the user criteria in structural design for region-specific adaptability. The proposed paradigm gathers information on the region, people’s expectations, visibility, and structural performance for the aesthetic design application. The proportion considerations in the application are subject to vary according to the region’s adaptability and performance. The proportion of the accumulated data influence in the application is determined using deep learning. In the learning paradigm, two-layered configurations for region-adaptability and performance measures are trained to provide aesthetic design application recommendations. Based on the suggestion and recommendation, the deep learning module is trained to rectify design errors. The training is independent of the previous two error and adaptability verification layers. It is performed using the qualified (selected) aesthetic design with a previous history of user satisfaction.

Published: August 2023

The use of hateful language in public debates and forums is becoming more common. However, this might result in antagonism and conflicts among individuals, which is undesirable in an online environment. Countries, businesses, and educational institutions are exerting their greatest efforts to develop effective solutions to manage this issue. In addition, recognizing such content is difficult, particularly in Arabic, due to a variety of challenges and constraints. Long-tailed data distribution is often one of the most significant issues in actual Arabic hate speech datasets. Pre-trained models, such as bidirectional encoder representations from transformers (BERT) and generative pre-trained transformers (GPT), have become more popular in numerous natural language processing (NLP) applications in recent years. We conduct extensive experiments to address data imbalance issues by utilizing oversampling methods and a focal loss function in addition to traditional loss functions. Quasi-recurrent neural networks (QRNN) are employed to fine-tune the cutting-edge transformer-based models, MARBERTv2, MARBERTv1, and ARBERT. In this context, we suggest a new approach using ensemble learning that incorporates best-performing models for both original and oversampled datasets. Experiments proved that our proposed approach achieves superior performance compared to the most advanced methods described in the literature.

Published: August 2023

A novel enhancement method to improve resolution and contrast has been proposed to address the issues of blurring and distortion commonly encountered in traditional patterns. Initially, a discrete wavelet transform, a stationary wavelet transform, and an interpolation algorithm are used to obtain high-resolution images of traditional patterns. Subsequently, improved singular value matrix coefficients and reconstructed gamma function are used to enhance the image contrast to obtain high-resolution and contrast-enhanced patterns. Experimental results demonstrate the efficacy of this method, as evidenced by improved evaluation indexes, such as mean square error, peak signal-to-noise ratio, and structural similarity, in comparison to other existing methods. The proposed method effectively improves the quality of traditional patterns and offers significant contributions to research on the restoration and protection of traditional patterns.

Background: Multi-arm, multi-stage (MAMS) platform trials can accelerate the identification of disease-modifying treatments for Parkinson’s disease (PD) but there is no current consensus on the optimal outcome measures (OM) for this approach. Objective: To provide an up-to-date inventory of OM for disease-modifying PD trials, and a framework for future selection of OM for such trials. Methods: As part of the Edmond J Safra Accelerating Clinical Trials in Parkinson Disease (EJS ACT-PD) initiative, an expert group with Patient and Public Involvement and Engagement (PPIE) representatives’ input reviewed and evaluated available evidence on OM for potential use in trials to delay progression of PD. Each OM was ranked based on aspects such as validity, sensitivity to change, participant burden and practicality for a multi-site trial. Review of evidence and expert opinion led to the present inventory. Results: An extensive inventory of OM was created, divided into: general, motor and non-motor scales, diaries and fluctuation questionnaires, cognitive, disability and health-related quality of life, capability, quantitative motor, wearable and digital, combined, resource use, imaging and wet biomarkers, and milestone-based. A framework for evaluation of OM is presented to update the inventory in the future. PPIE input highlighted the need for OM which reflect their experience of disease progression and are applicable to diverse populations and disease stages. Conclusion: We present a range of OM, classified according to a transparent framework, to aid selection of OM for disease-modifying PD trials, whilst allowing for inclusion or re-classification of relevant OM as new evidence emerges.
NP on Logarithmic Space
Authors: Vega Frank
Published: August 2023

\(P\) versus \(NP\) is considered as one of the most important open problems in computer science. This consists in knowing the answer of the following question: Is \(P\) equal to \(NP\)? It was essentially mentioned in 1955 from a letter written by John Nash to the United States National Security Agency. However, a precise statement of the \(P\) versus \(NP\) problem was introduced independently by Stephen Cook and Leonid Levin. Since that date, all efforts to find a proof for this problem have failed. Another major complexity classes are \(L\) and \(NL\). Whether \(L = NL\) is another fundamental question that it is as important as it is unresolved. We prove that \(NP \subseteq NSPACE(\log^{2} n)\) just using \(1L\)-reductions.

During the scientific research of any criminal-legal phenomenon or process, it is considered necessary to conduct an analysis of the origin of this phenomenon in a foreign country. This provides an opportunity not only to grasp the essence and understand the content of the subject of research, but also to develop effective countermeasures and borrow foreign experience. This becomes especially important in matters of combating corruption, when the criminal acts of officials reach not only domestic, but also international scales.Scientists’ positions, as well as the provisions of the current legislation in Ukraine and the Republic of Poland concerning the definition of the criminal law provisions for liability for corruption offenses are being researched, which is made on the relevant differences regarding the legislative enactment of the concept of “corruption” and its definition in the criminal law theory. Accordingly, a comparative approach to the methods of legislative consolidation of anti-corruption provides an opportunity to understand the social conditioning of the emergence of this phenomenon.Taking into account the integration processes in all spheres of life activity of society, the difference in the method of normative consolidation of actions forming such a phenomenon as corruption was revealed. This, in turn, not only indicates different forms of legislative fixation of the concept of the phenomenon, but also causes difficulties in the exchange of law enforcement practice, which causes a number of problems for both the relevant law enforcement agencies and ordinary citizens. A clear division and distinction between provisions on liability for corruption and corruption-related offenses was revealed.Taking into account the position of the domestic criminal law doctrine, the analysis of the current Polish legislation provided an opportunity to formulate real options for borrowing foreign experience to solve the specified problems.

Teologi Islam: Argumen Alexander Treiger tentang 'Ilmu Kalam
Authors: Utomo Fendi
Published: August 2023

This article examines the ideas of Alexander Treiger in conceptualizing the origins of Kalam in the debate culture of Late Antiquity. Treieger's ideas refer to Michael Cook and Jack Tannous who argue that the Kalām style of argument originates from Christological debates which are then absorbed into Muslim practice through the mediation of Arab Christian circles in Syria and Iraq. Treiger reviews the Science of Kalam on ontological historical aspects and terminological debates, which are rarely highlighted by Muslim scholars. From the results of the analysis of what was studied by Treiger, it was concluded that Treiger argued that the originality of Kalam was divided into three parts namely; the origins of the kalam argument, the debate about Qadar (human free will versus God's destiny) and in the final section discusses three Muslim texts on Qadar which are associated with Hasan bin Muhammad al-Hanafiyah, Umar bin Abdul Aziz and Hasan Al-Bashri. Alexander Treiger is of the view that the science of kalam in general is the influence of Muslim-Christian interactions in Syria. However, unfortunately Treiger does not have enough argumentative data to support his assumption that theology has been influenced by Christianity.
Saliva-Based Test as an Alternative Diagnosis for SARS-CoV-2 Patient
Authors: Istiati  , Esa Ilham Mei Sasmita
Published: August 2023

Respiratory system is affected by a novel type of virus known as Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The gold standard for its identification is the real-time reverse transcription polymerase chain reaction (rRT-PCR) test, despite being invasive and dangerous to medical workers during the sample-collecting process. However, major salivary glands including the parotid, submandibular, and sublingual, as well as smaller glands dispersed throughout the mouth cavity, release saliva, a hypotonic fluid, containing biomarkers that can be used to identify both local and systemic disorders, including SARS-CoV-2. This fluid can be utilized as a non-invasive, low-risk diagnostic test by medical professionals since it provides insights into patient's overall health. This study aims to determine the potential of saliva as a substitute for other SARS-CoV-2 diagnostic methods. The results from analysis of 5 scientific publications, showed that saliva contained SARS-CoV-2 virus RNA, making it suitable for patient diagnostic testing. Considering the results, the fluid was discovered to be an alternative diagnostic test for patient with the virus.

Authors: Almeida Anderson Tadeu de Santi Barbosa de
Published: August 2023

Esforços têm sido feitos há anos para minimizar os riscos de Segurança e Saúde no Trabalho (SST), mas os registros de lesões continuam sendo um motivo constante de preocupações em todo o mundo. Muitas empresas frequentemente implementam a tecnologia como uma hierarquia administrativa de controle. No entanto, as tecnologias também podem influenciar ativamente as práticas seguras no nível gerencial para o administrativo. Esta pesquisa examina os riscos de segurança elétrica na construção civil, como base para o estudo da viabilidade do uso de tecnologia destinada à integração da cultura de segurança no nível administrativo de mitigação de riscos de SST. É introduzido o conceito “habitus” (hábito), que sugere uma possibilidade para o estabelecimento de uma cultura que aumente o desempenho de segurança dos trabalhadores e se integre às suas práticas por meio da tecnologia da informação de ponta. Um aplicativo protótipo para treinamento em SST baseado em tecnologia de Realidade Virtual Móvel (MVR) é demonstrado para ajudar a estabelecer hábitos nas práticas diárias dos trabalhadores em uma empresa do ramo estudado e, em última análise, mitigar os riscos de SST no nível administrativo de projetos de construção. Embora seja um estudo piloto em segurança elétrica, sua aplicação não se limita a esta área e é escalável para outros riscos de SST.
