Authors: Xian Yuanqing , Liu Guangjun , Fan Jinfu , Yu Yang , Wang Zhongjie
Published: November 2021

Copper elbows are an important product in industry. They are used to connect pipes for transferring gas, oil, and liquids. Defective copper elbows can lead to serious industrial accidents. In this paper, a novel model named YOT-Net (YOLOv3 combined triplet loss network) is proposed to automatically detect defective copper elbows. To increase the defect detection accuracy, triplet loss function is employed in YOT-Net. The triplet loss function is introduced into the loss module of YOT-Net, which utilizes image similarity to enhance feature extraction ability. The proposed method of YOT-Net shows outstanding performance in copper elbow surface defect detection.
Null Subcarrier Index Modulation in OFDM Systems for 6G and Beyond
Authors: Eren Tuncay , Akan Aydin
Published: November 2021

Computational complexity is one of the drawbacks of orthogonal frequency division multiplexing (OFDM)-index modulation (IM) systems. In this study, a novel IM technique is proposed for OFDM systems by considering the null subcarrier locations (NSC-OFDM-IM) within a predetermined group in the frequency domain. So far, a variety of index modulation techniques have been proposed for OFDM systems. However, they are almost always based on modulating the active subcarrier indices. We propose a novel index modulation technique by employing the part of the transmitted bit group into the null subcarrier location index within the predefined size of the subgroup. The novelty comes from modulating null subcarriers rather than actives and reducing the computational complexity of the index selection and index detection algorithms at the transmitter and receiver, respectively. The proposed method is physically straightforward and easy to implement owing to the size of the subgroups, which is defined as a power of two. Based on the results of our simulations, it appeared that the proposed NSC-OFDM-IM does not suffer from any performance degradation compared to the existing OFDM-IM, while achieving better bit error rate (BER) performance and improved spectral efficiency (SE) compared to conventional OFDM. Moreover, in terms of computational complexity, the proposed approach has a significantly reduced complexity over the traditional OFDM-IM scheme.

Authors: Luo Qiwu , Jiang Weiqiang , Su Jiaojiao , Ai Jiaqiu , Yang Chunhua
Published: November 2021

Steel strip acts as a fundamental material for the steel industry. Surface defects threaten the steel quality and cause substantial economic and reputation losses. Roll marks, always occurring periodically in a large area, are put on the top of the list of the most serious defects by steel mills. Essentially, the online roll mark detection is a tiny target inspection task in high-resolution images captured under harsh environment. In this paper, a novel method—namely, Smoothing Complete Feature Pyramid Networks (SCFPN)—is proposed for the above focused task. In particular, the concept of complete intersection over union (CIoU) is applied in feature pyramid networks to obtain faster fitting speed and higher prediction accuracy by suppressing the vanishing gradient in training process. Furthermore, label smoothing is employed to promote the generalization ability of model. In view of lack of public surface image database of steel strips, a raw defect database of hot-rolled steel strip surface, CSU_STEEL, is opened for the first time. Experiments on two public databases (DeepPCB and NEU) and one fresh texture database (CSU_STEEL) indicate that our SCFPN yields more competitive results than several prestigious networks—including Faster R-CNN, SSD, YOLOv3, YOLOv4, FPN, DIN, DDN, and CFPN.

Published: November 2021

As a pivotal technological foundation for smart home implementation, non-intrusive load monitoring is emerging as a widely recognized and popular technology to replace the sensors or sockets networks for the detailed household appliance monitoring. In this paper, a probability model framed ensemble method is proposed for the target of robust appliance monitoring. Firstly, the non-intrusive load disaggregation-oriented ensemble architecture is presented. Then, dictionary learning model is utilized to formulate the individual classifier, while the sparse coding-based approach is capable of providing multiple solutions under greedy mechanism. Furthermore, a fully probabilistic model is established for combined classifier, where the candidate solutions are all labelled with probability scores and evaluated via two-stage decision-making. The proposed method is tested on both low-voltage network simulator platform and field measurement datasets, and the results show that the proposed ensemble method always guarantees an enhancement on the performance of non-intrusive load disaggregation. Besides, the proposed approach shows high flexibility and scalability in classification model selection. Therefore, by initializing the architecture and approach of ensemble method-based NILM, this work plays a pioneer role in using ensemble method to improve the robustness and reliability of non-intrusive appliance monitoring.
A Socially-Based Redesign of Sustainable Food Practices: Community Supported Agriculture in Italy
Authors: Piccoli Alessandra , Rossi Adanella , Genova Angela
Published: November 2021

Several grassroots initiatives in the last two decades have shown the need for different food practices that should be locally based and founded on ethical goals of social and environmental justice. Among the many “alternative food networks”, the Community Supported Agriculture model is particularly significant and interesting. By redefining meanings and social norms around food practices, this model actualizes significant processes of food re-socialization and re-territorialization. Focusing on Italy, this study aims to contribute to the understanding of the potential of this model. It does so through two investigations carried out in 2019 and 2020, aimed at analyzing, respectively, structural and organizational aspects of CSAs and the features of resilience shown by these initiatives during the first COVID-19 pandemic lockdown. On the whole, the two surveys give us the image of a radically innovative experience, potentially capable of deeply redefining production and consumption practices, being rooted in socially-shared knowledge, motivations, willingness, commitment and sense of community. In addition to being characterized by a determination to pursue sustainability and equity goals, the model shows a remarkable character of resilience thanks to the original arrangements that the common value basis and the strong sense of interdependence and solidarity of its members can provide.
Sustainable People Home-Work Logistics: An Integrated Model of Circular Economy in the Chiampo Valley
Authors: Faccio Maurizio , Finco Serena , Zennaro Ilenia
Published: November 2021

Logistics activities, e.g., transportations of goods and people, are responsible for at least one-third of energy consumption and Green House Gas (GHG) emissions. About 70% of them are related to people’s mobility, with millions of cars moving every day. The people home-work logistics represents undoubtedly an important part of it since flows are concentrated on fixed time windows (beginning, lunch break, and end of the working day) creating huge traffic congestions and negative impacts on time, economics, and the environment. This study proposes an integrated model, summarized through a methodological framework, where three actors (companies, public administrations and local shops) work together aiming to economically incentivize the use of sustainable mobility systems. Three are the main elements of the proposed sustainable people home-work logistics model: (1) the economic self-sustainability of the incentives, funded in different ways by the actors, (2) the scalability, thanks to the possibility to add new territories to the project and (3) the territorial circular economy generated thanks to the incentive’s destinations and the public-private integration. Starting from survey questionnaires and territorial attributes, sustainable mobility ways are defined. Then, participant workers are monitored by activating a mobile app, called Ecoattivi, during their home-work journeys. In such a way, workers can directly analyze their sustainable mobility and reach the possibility to accumulate and spend money in local shops as a function of the saved CO2. On the other hand, companies and public administrations compete in a special ranking for sustainable mobility. The methodological framework has been applied to a real case study in the Chiampo Valley, in the northeast of Italy, where about 10 small towns and dozens of companies in 2020 started the “Bike to Work Valchiampo” project.
Use of the e-Delphi Method to Validate the Corporate Reputation Management Maturity Model (CR3M)
Authors: Głuszek Ewa
Published: November 2021

Information and communication technologies (ICT) have allowed the modification of many research methods based on communication. One of them is the Delphi method, especially e-Delphi. The two main areas of application of the Delphi method are traditional forecasting, but recently also the conceptual framework development of a model or theory, especially in complex domains and those where empirical research is lacking. The aim of the study was to assess the substantive accuracy (validation) of the enterprise reputation management maturity model (CR3M) using the modified e-Delphi. The final model will be tested in selected companies in the future (in the next stage of the research). Maturity models have long been regarded as tools for assessing skills in some field. The CR3M model originally included 96 practices (in four areas: communication management, corporate social responsibility, reputational risk and quality), the implementation of which was considered to be a maturity indicator. The basis for the development of the model was the literature on the subject and the existing partial maturity models. Ten experts (five theorists and five practitioners) participated in the study and assessed the appropriateness of including practices in the model and their validity, using a 5-point Likert scale. The questionnaire consisted of three questions. In two rounds of the Delphi study, an expert consensus was reached (in accordance with a priori established indicators) regarding the retention 70 out of 96 practices originally included in the model (26 deleted). The model retained 18 practices in the area of Communication Management, 14 practices in the area of Corporate Social Responsibility, 18 practices in the field of Reputation Risk Management and 20 practices in the field of Quality Management. Modification of the maturity model-reducing the number of practices included in the model increased its applicability. At the same time, 89% of experts found the presented maturity model a useful tool for self-assessment and improvement of reputation management. The modified e-Delphi procedure can be considered as an effective methodology for validating complex conceptual models.

Published: November 2021

Mainland China’s economy is growing rapidly, with China-made electronic products selling around the world. Taiwan’s electronics groups running operations or production locations in Mainland China have performed strongly in recent years. At one time more than 90% of the world’s laptops were manufactured by Taiwanese makers, largely in China. This study assessed the sustainability operating performance of the top 20 Taiwanese electronic groups (including 272 companies) with an average of 38 years of sustained operation in China, using the Data Envelopment Analysis Method (DEA) to measure the performance and operating efficiency of the group as a whole, with net operating revenue and pre-tax profit margin as the output elements, and total assets, capital, and total expenses as input elements, to assess whether changes in operating performance and productivity over the three-year period (2018–2020) are significant. The results showed that two Taiwanese electronics groups (Quanta Computer and Catcher Technology) were relatively efficient during the study period and that the overall productivity of the electronics groups was in a state of sustainability. This study uses the industrial cluster viewpoint to evaluate the sustainability operating performance of the groups. Results show that using DEA for performance evaluation is both comprehensive and practical. The findings of this study may be used as a reference in creating sustainable operations and improving a firm’s production efficiency through the evaluation of firm resource allocation.

This study aimed to examine the spatial structure of the tourist attraction cooperation network in the Yangtze River Delta, from the perspective of tourist flow. This study conducted spatial and social network analyses of 470 popular tourist attractions in the Yangtze River Delta region of China, accounting for the occurrence and co-occurrence of tourist attraction information in tourist travel notes. The analyzed tourist attractions show an obvious spatial agglomeration effect, including four high-density agglomeration areas and two medium-density agglomeration areas. Degree centrality, closeness centrality, and betweenness centrality were used to examine the tourism function, distribution function, and connection function of nodes in the network; nodes were divided into various types of roles according to their function. There are eight condensed subgroups, but their scales are unbalanced. In these condensed subgroups, several tourist attractions with an intermediate function can be selected as transit and stopover points on tourist routes. This study can contribute to the understanding of tourists’ spatial behavior, clarify the role and status of nodes in the cooperation network of tourist attractions based on tourism flow, and help them to formulate measures for the joint marketing of tourist attractions, and promote the development of tourism in the Yangtze River Delta region.

Authors: Budiyanto Eko Hariyadi , Gurning Raja Oloan Saut , Pitana Trika
Published: November 2021

A container terminal is a facility used to collect containers from the hinterland and ports for distribution to the end destination. Based on these essential functions, container terminals often reflect the economic conditions in a country. Many studies have recently examined the use of business impact analysis (BIA) when disruption happens at a container terminal. In sustainability and business impact research, the economy is one of the prioritized aspects of impact analysis. The impact related to the economic aspect is generally caused by disruptions resulting from natural disasters, pandemics, and human activities (terrorists, labor issues, and lockouts). Until this article was conducted, there was still little literature explaining the business impact analysis procedures with case studies of disruptions in container terminals related to operational constraints. This paper aims to provide a perspective in deepening and adapting the BIA procedure initially general into an analysis that can be applied to the container terminal business. This paper takes a case study of BIA in a container terminal caused by electrical disruption. Based on the research, six categories of disruption became a concern when the port’s electricity supply stopped, i.e., decreased productivity, economic loss, reduced employee productivity, decreased numbers of customers, a decline in company reputation, and wasted energy.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.

Published: November 2021

The main danger of a brain aneurysm (a sack-like bulge on the vessel wall) is that in the event of a rupture a severe hemorrhage can occur which may cause death. However, if doctors have tools at their disposal, such as numerical models and simulations for analyzing patient-specific blood vessels, they could use them to decide if a particular treatment is necessary and if so, when. For such models, the different mechanical characteristics of the flow control devices are the input data. Several of these mechanical properties of the devices, such as modulus of elasticity and tensile strength, are determined by tensile testing. In the course of our research, we have developed a clamping device suitable for uniaxial tensile testing of flow diverter stents.

Published: November 2021

Persistent organic pollutants (POPs) and emerging pollutants (EP) are characterized by their difficulty to be removed through biological oxidation processes (BOPs); they persist in the environment and could have adverse effects on the aquatic ecosystem and human health. The electro-oxidation (EO) process has been successfully used as an alternative technique to oxidize many kinds of the aforementioned pollutants in wastewater. However, the EO process has been criticized for its high energy consumption cost and its potential generation of by-products. In order to decrease these drawbacks, its combination with biological oxidation processes has been reported as a solution to reduce costs and to reach high rates of recalcitrant pollutants removal from wastewaters. Thus, the location of EO in the treatment line is an important decision to make, since this decision affects the formation of by-products and biodegradability enhancement. This paper reviews the advantages and disadvantages of EO as a pre and post-treatment in combination with BOPs. A perspective of the EO scale-up is also presented, where hydrodynamics and the relationship of A/V (area of the electrode/working volume of the electrochemical cell) experiments are examined and discussed.

Authors: Sheremet Elina , Kalutskova Natalia , Dekhnich Vladimir
Published: November 2021

Visual characteristics of landscapes are important factors for the assessment of tourist and recreational potential of territories. At present, a number of methodological approaches are applied to assess the visual characteristics of landscapes. They can be divided into traditional, associated exclusively with field research, and innovative, which is based on remote sensing data (RSD) of high spatial resolution and GIS technologies. Field assessment of the visual quality of landscapes utilizes a system of numerous elementary indicators to minimize subjectivity of assessment. They are conducted within separate areas or touristic routes. In its turn, modern GIS and high quality of remote sensing data allow assessing of most indicators of the visual quality of landscapes for any observation point on the entire territory. The main task of our research is to verify the results of automated processing of ultra-high resolution aerial photographs obtained from unmanned aerial vehicles (UAV) by field observations on a touristic route. The research was carried out on the territory of the “Belogradchik Rocks” Geopark (North-West Bulgaria). In our study, we estimated 4 out of 28 aesthetic indicators—the amount of mountain peaks visible from a site, the amount of mountain peaks on the skyline, the percentage of the forest-covered area, and the amount of open spaces in the wooded landscape. The obtained results confirmed that our approach allows calculating these aesthetic indicators at an accuracy level comparable to field observations.

Authors: Yakimova Olga , Samsonov Timofey , Potemkin Daniil , Usmanova Elina
Published: November 2021

The article is devoted to the problem of evaluating the detailing of spatial data. In geoinformatics, spatial data detailing determines how detailed a particular object is representeda map image, and the detail score allows you to analyze the permissible accuracy of spatial objects for a specific user task. An approach to the definition of detailing concept is proposed. The evaluation of the object’s detail depends on its characteristics: geometric, semantic, and topological. A study is being conducted to select the geometric characteristics of the object that reflect its detail. For linear objects, in addition to the characteristics of the line as a whole (length, number of points, sinuosity, average rotation angle), it is suggested to consider its smaller details, such as bends and triplets. A bend is a section of a line where the angle of rotation retains its sign. A triplet is a combination of three consecutive points. Based on the results of the study, the geometric characteristics that change in the trend depending on the scale were selected.

The paper presents the developed software for assessing map detail—the MapAnalyser toolbar for the QGIS geoinformation system. The functional capabilities of the developed software are described. The toolbar allows you to get the geometric, semantic, and topological characteristics of a layer or set of layers, as well as to evaluate the graphical complexity of a map image based on RlE encoding. The program code is written in the PyQGIS language. The software has passed state registration and is hosted on the github server. With its help, new results were obtained on the evaluation of spatial data granularity.

New software, embedded in QgIS, to assess the detail of the map and spatial data, based on taking into account geometric and symbolic (used in the display) parameters. The software allows to calculate the metrics of spatial data detail, as well as to assess the complexity of the cartographic image. It’s can be used in the integration of data obtained from different sources, assess the compliance of data detail and the map scale, to assess the complexity of the map for different purposes and scales.
Modern studies of water dynamics in the north-western part of Black sea from LADCP measurements
Authors: Morozov Alexey , Mankovskaya Ekaterina
Published: November 2021

In this work a result of preliminary analysis of current measurements collected in fourteen large-scale expeditions of the Marine Hydrophysical Institute in 2016–2019 in the north-eastern part of the Black Sea is presented. It is shown that the use of the Lowered Acoustic Doppler Current Profiler (LADCP) significantly increases the information content of the expedition materials, opening up new opportunities in the experimental study of water dynamics.

Based on the materials of the expeditions, it was found that the upper layer of shear baroclinic currents in the measurement area is limited by the isopycnic depth with a potential density of ~16.75 kg/m3 (~350 m). At this depth, the variability of the buoyancy frequency with the depth changes from a power-law to an exponential dependence. The same depth limits the penetration of seasonal variations of the average kinetic energy into the water column. The highest values of the average kinetic energy are observed in April-May and November–December, the lowest—in June–August. The ratio of the maximum energy values (summer) to its minimum values (spring, late autumn, winter) was ~3.

The Rim Black Sea Current is most pronounced near the Crimean Peninsula in the spring and winter seasons. In summer and autumn, the horizontal distribution of the current velocity in depths of 30–80 m is less structured, which is caused by the seasonal intensification of mesoscale processes.

At a number of stations, the current velocity profiles contain fragments with a well-defined harmonic variability of the current velocity components with depth, which can be interpreted as the manifestation of near-inertial internal waves. In most cases, the rotation of the current velocity vector with depth occurs clockwise, which determines the main direction of propagation of the inertial internal waves into the water column. The example of one of the stations shows the significant contribution of such waves to the value of shear. This fact suggests a significant influence of near-inertial internal waves on the processes of vertical turbulent exchange in the water column.

Published: November 2021

In the modern doctrine of criminal law, a detailed study of economic crimes located in Chapter 22 of the Criminal Code of the Russian Federation revealed a certain tendency of the absence of system-forming signs of this group of criminal encroachments. A serious analysis of the signs of the corpus delict provided for in Article 169 of the Criminal Code of the Russian Federation was carried out in order to further improve them. The purpose of this work is to study the legal potential of the article and the factors that prevent the implementation of its provisions in practice. Achieving this goal is possible by solving such tasks as identifying the legal nature of objective and subjective signs of a crime under Article 169 of the Criminal Code of the Russian Federation, studying the problems of applying this article and identifying possible ways to resolve them. The relevance and significance of the existence of this corpus delict for the protection of the interests of an entrepreneur in the Russian Federation is established. The problems of judicial practice that prevent the real application of the provisions of Article 169 of the Criminal Code of the Russian Federation are identified. The emphasis is placed on the involvement of officials in the commission of criminal acts against business entities. Some changes in the criminal legislation are proposed, which will exclude the identification of the provisions of Article 169 of the Criminal Code of the Russian Federation with the category of "dead" norms. In this regard, it seems quite justified to consider in more detail the provisions of Article 169 of the Criminal Code of the Russian Federation, which provides for liability for obstruction of legitimate entrepreneurial or other activities.

Funeral and ritual practices in cave sites during the Late Bronze Age and Early Iron Age have been recognised in multiple sites south of the Carpathians. This paper presents the first evidence for the funeral and ritual use of cave sites with such chronology north of the Carpathians. Unburned human remains dated to Ha B and Ha C/D have been identified in two cave sites (Zbójecka Cave and Bramka Rockshelter) located 500 m apart, in the Polish Jura. Additionally, a pottery deposit dated to Ha B2-C has been found in a third cave (Ciasna Cave) situated near the aforementioned sites. The paper analyses these finds in the context of the local Lusatian culture settlement and the already recognised traces of Lusatian cave site use in the studied karstic region. The results give ground to search for more evidence of ritual cave use in the Late Bronze Age and Early Iron Age.
