Prophetic Disappointment and Ideological Change among Israeli Settlers’ Rabbis: The Case of Rabbis Yehuda Amital and Shmuel Tal
Authors: Inbari Motti
Published: November 2021

In this article, I examine the role of prophetic disappointment in creating ideological change. I discuss the response of two Orthodox rabbis, Rabbi Yehuda Amital (1924–2010) and Rabbi Shmuel Tal (b. 1962), to the crisis of faith they encountered regarding the role of Zionism in the messianic drama. This research describes the process of religious switching they have gone through due to failure of prophetic faith. This work argues that their transformation was an attempt to cope with the tension that results from cognitive dissonance in two different instances while blaming a third party for misunderstanding the true will of God. Their religious switching was an act of theodicy, justifying God’s justice, while renouncing their previous held beliefs.
SEE-TREND: SEcurE Traffic-Related EveNt Detection in Smart Communities
Authors: Olariu Stephan , Popescu Dimitrie C.
Published: November 2021

It has been widely recognized that one of the critical services provided by Smart Cities and Smart Communities is Smart Mobility. This paper lays the theoretical foundations of SEE-TREND, a system for Secure Early Traffic-Related EveNt Detection in Smart Cities and Smart Communities. SEE-TREND promotes Smart Mobility by implementing an anonymous, probabilistic collection of traffic-related data from passing vehicles. The collected data are then aggregated and used by its inference engine to build beliefs about the state of the traffic, to detect traffic trends, and to disseminate relevant traffic-related information along the roadway to help the driving public make informed decisions about their travel plans, thereby preventing congestion altogether or mitigating its nefarious effects.

Authors: Kim Seokgoo , Choi Joo-Ho , Kim Nam H.
Published: November 2021

Prognostics and health management (PHM) has become an essential function for safe system operation and scheduling economic maintenance. To date, there has been much research and publications on component-level prognostics. In practice, however, most industrial systems consist of multiple components that are interlinked. This paper aims to provide a review of approaches for system-level prognostics. To achieve this goal, the approaches are grouped into four categories: health index-based, component RUL-based, influenced component-based, and multiple failure mode-based prognostics. Issues of each approach are presented in terms of the target systems and employed algorithms. Two examples of PHM datasets are used to demonstrate how the system-level prognostics should be conducted. Challenges for practical system-level prognostics are also addressed.

Published: November 2021

In this paper, in order to improve the durability of optical fiber grating hydrogen sensors, an optical fiber grating hydrogen sensor with high precision, stability, and durability is prepared. Based on the simplified two-dimensional model and finite element analysis, the effects of film thickness, coating speed, and coating times on the residual Mises equivalent stress between the sensor film and substrate were studied, and the optimum coating parameters were determined. The finite element analysis results show that the residual equivalent stress between the film and the substrate increases with the increase in the film thickness between 50 and 150 nm. The range of 200–250 nm is relatively stable, and the value is small. The coating speed has almost no effect on the residual equivalent stress. When the thickness of the film is 200 nm, the residual equivalent stress decreases with the increase in coating times, and the equivalent force is the lowest when the film is coated three times. The best coating parameters are the thickness of 200 nm, the speed of 62.5 μm/s, and the times of coating three times. The results of finite element analysis are verified by the hydrogen sensitivity test and durability test.
The Application of Quaternions to Strap-Down MEMS Sensor Data
Authors: Dickson Peter M. , Rae Philip J.
Published: November 2021

We describe the mathematical transformations required to convert the data recorded using typical 6-axis microelectromechanical systems (MEMS) sensor packages (3-axis rate gyroscopes and 3-axis accelerometers) when attached to an object undergoing a short duration loading event, such as blast loading, where inertial data alone are sufficient to track the object motion. By using the quaternion description, the complex object rotations and displacements that typically occur are translated into the more convenient earth frame of reference. An illustrative example is presented where a large and heavy object was thrown by the action of a very strong air blast in a complex manner. The data conversion process yielded an accurate animation of the object’s subsequent motion.
Environmental Monitoring of the Littoral Zone of Lake Baikal Using a Network of Automatic Hydro-Meteorological Stations: Development and Trial Run
Authors: Makarov Mikhail , Aslamov Ilya , Gnatovsky Ruslan
Published: November 2021

An automatic hydro-meteorological station (AHMS) was designed to monitor the littoral zone of Lake Baikal in areas with high anthropogenic pressure. The developed AHMS was installed near the Bolshiye Koty settlement (southern basin). This AHMS is the first experience focused on obtaining the necessary competencies for the development of a monitoring network of the Baikal natural territory. To increase the flexibility of adjustment and repeatability, we developed AHMS as a low-cost modular system. AHMS is equipped with a weather station and sensors measuring water temperature, pH, dissolved oxygen, redox potential, conductivity, chlorophyll-a, and turbidity. This article describes the main AHMS functions (hardware and software) and measures taken to ensure data quality control. We present the results of the first two periods of its operation. The data acquired during this periods have demonstrated that, to obtain accurate measurements and to detect and correct errors that were mainly due to biofouling of the sensors and calibration bias, a correlation between AHMS and laboratory studies is necessary for parameters such as pH and chlorophyll-a. The gained experience should become the basis for the further development of the monitoring network of the Baikal natural territory.
Neuromuscular Electrical Stimulation to Immobilized Lower Extremities Directly Following Orthopaedic Surgery in Three Children with Cerebral Palsy: A Case Series
Authors: Greve Kelly , Colvin Caroline
Published: November 2021

Cerebral palsy (CP) is a non-progressive, neurological disorder often resulting in secondary musculoskeletal impairments affecting alignment and function which can result in orthopaedic surgery. Neuromuscular electrical stimulation (NMES) is a modality that can be used for rehabilitation; however, NMES immediately following orthopaedic surgery in children with CP using surface electrodes has not been previously reported. The purpose of this case series is to describe the novel use of NMES in the acute rehabilitation phase directly after orthopaedic surgery. This case series included three children with spastic diplegia CP, Gross Motor Function Classification System level II who underwent Single Event Multi-Level orthopaedic Surgery. Each long leg cast contained window cast cut-outs to allow for surface electrode placement for daily NMES intervention to the quadriceps muscles while immobilized. Children were assessed pre- and post-operatively using the Functional Mobility Scale (FMS), Gross Motor Function Measure (GMFM-66), and 6-Minute Walk Test (6MWT). All children demonstrated no adverse effects using NMES intervention and had improvements in the 6MWT. Most children demonstrated gains in the FMS and GMFM-66. Use of NMES through window cast-cuts in a long leg cast is a novel practice approach for delivery of early rehabilitation following lower extremity orthopaedic surgery.
An Overdispersed Black-Box Variational Bayesian–Kalman Filter with Inaccurate Noise Second-Order Statistics

Published: November 2021

Aimed at the problems in which the performance of filters derived from a hypothetical model will decline or the cost of time of the filters derived from a posterior model will increase when prior knowledge and second-order statistics of noise are uncertain, a new filter is proposed. In this paper, a Bayesian robust Kalman filter based on posterior noise statistics (KFPNS) is derived, and the recursive equations of this filter are very similar to that of the classical algorithm. Note that the posterior noise distributions are approximated by overdispersed black-box variational inference (O-BBVI). More precisely, we introduce an overdispersed distribution to push more probability density to the tails of variational distribution and incorporated the idea of importance sampling into two strategies of control variates and Rao–Blackwellization in order to reduce the variance of estimators. As a result, the convergence process will speed up. From the simulations, we can observe that the proposed filter has good performance for the model with uncertain noise. Moreover, we verify the proposed algorithm by using a practical multiple-input multiple-output (MIMO) radar system.
A Two-Filter Approach for State Estimation Utilizing Quantized Output Data

Published: November 2021

Filtering and smoothing algorithms are key tools to develop decision-making strategies and parameter identification techniques in different areas of research, such as economics, financial data analysis, communications, and control systems. These algorithms are used to obtain an estimation of the system state based on the sequentially available noisy measurements of the system output. In a real-world system, the noisy measurements can suffer a significant loss of information due to (among others): (i) a reduced resolution of cost-effective sensors typically used in practice or (ii) a digitalization process for storing or transmitting the measurements through a communication channel using a minimum amount of resources. Thus, obtaining suitable state estimates in this context is essential. In this paper, Gaussian sum filtering and smoothing algorithms are developed in order to deal with noisy measurements that are also subject to quantization. In this approach, the probability mass function of the quantized output given the state is characterized by an integral equation. This integral was approximated by using a Gauss–Legendre quadrature; hence, a model with a Gaussian mixture structure was obtained. This model was used to develop filtering and smoothing algorithms. The benefits of this proposal, in terms of accuracy of the estimation and computational cost, are illustrated via numerical simulations.
Performance Analyses of Energy Detection Based on Square-Law Combining in MIMO-OFDM Cognitive Radio Networks
Authors: Lorincz Josip , Ramljak Ivana , Begušić Dinko
Published: November 2021

Cognitive radio (CR) technology has the potential to detect and share the unutilized spectrum by enabling dynamic spectrum access. To detect the primary users’ (PUs) activity, energy detection (ED) is widely exploited due to its applicability when it comes to sensing a large range of PU signals, low computation complexity, and implementation costs. As orthogonal frequency-division multiplexing (OFDM) transmission has been proven to have a high resistance to interference, the ED of OFDM signals has become an important local spectrum-sensing (SS) concept in cognitive radio networks (CRNs). In combination with multiple-input multiple-output (MIMO) transmissions, MIMO-OFDM-based transmissions have started to become a widely accepted air interface, which ensures a significant improvement in spectral efficiency. Taking into account the future massive implementation of MIMO-OFDM systems in the fifth and sixth generation of mobile networks, this work introduces a mathematical formulation of expressions that enable the analysis of ED performance based on the square-law combining (SLC) method in MIMO-OFDM systems. The analysis of the ED performance was done through simulations performed using the developed algorithms that enable the performance analysis of the ED process based on the SLC in the MIMO-OFDM systems having a different number of transmit (Tx) and receive (Rx) communication branches. The impact of the distinct factors including the PU Tx power, the false alarm probability, the number of Tx and Rx MIMO branches, the number of samples in the ED process, and the different modulation techniques on the ED performance in environments with different levels of signal-to-noise ratios are presented. A comprehensive analysis of the obtained results indicated how the appropriate selection of the analyzed factors can be used to enhance the ED performance of MIMO-OFDM-based CRNs.

Published: November 2021

Towards clarifying the spatio-temporal neurotransmitter distribution, potentiometric redox sensor arrays with 23.5-µm resolution were fabricated. The sensor array based on a charge-transfer-type potentiometric sensor comprises 128×128 pixels with gold electrodes deposited on the surface of pixels. The sensor output corresponding to the interfacial potential of the electrode changed logarithmically with the mixture ratio of K3Fe(CN)6 and K4Fe(CN)6, where the redox sensitivity reached 49.9 mV/dec. By employing hydrogen peroxidase as an enzyme and ferrocene as an electron mediator, the sensing characteristics for hydrogen peroxide (H2O2) were investigated. The analyses of the sensing characteristics revealed that the sensitivity was about 44.7 mV/dec., comparable to the redox sensitivity, while the limit of detection (LOD) was achieved to be 1 µM. Furthermore, the oxidation state of the electron mediator can be the key to further lowering the LOD. Then, by immobilizing oxidizing enzyme for H2O2 and glutamate oxidase, glutamate (Glu) measurements were conducted. As a result, similar sensitivity and LOD to those of H2O2 were obtained. Finally, the real-time distribution of 1 µM Glu was visualized, demonstrating the feasibility of our device as a high-resolution bioimaging technique.

Authors: Nurzynska Karolina , Skurowski Przemysław , Pawlyta Magdalena , Cyran Krzysztof
Published: November 2021

The goal of the WrightBroS project is to design a system supporting the training of pilots in a flight simulator. The desired software should work on smart glasses supplementing the visual information with augmented reality data, displaying, for instance, additional training information or descriptions of visible devices in real time. Therefore, the rapid recognition of observed objects and their exact positioning is crucial for successful deployment. The keypoint descriptor approach is a natural framework that is used for this purpose. For this to be applied, the thorough examination of specific keypoint location methods and types of keypoint descriptors is required first, as these are essential factors that affect the overall accuracy of the approach. In the presented research, we prepared a dedicated database presenting 27 various devices of flight simulator. Then, we used it to compare existing state-of-the-art techniques and verify their applicability. We investigated the time necessary for the computation of a keypoint position, the time needed for the preparation of a descriptor, and the classification accuracy of the considered approaches. In total, we compared the outcomes of 12 keypoint location methods and 10 keypoint descriptors. The best scores recorded for our database were almost 96% for a combination of the ORB method for keypoint localization followed by the BRISK approach as a descriptor.

Low Correlation Interference OFDM-NLFM Waveform Design for MIMO Radar Based on Alternating Optimization
Authors: Liu Tianqu , Sun Jinping , Li Qing , Hao Zhimei , Wang Guohua
Published: November 2021

The OFDM chirp signal is suitable for MIMO radar applications due to its large time-bandwidth product, constant time-domain, and almost constant frequency-domain modulus. Particularly, by introducing the time-frequency structure of the non-linear frequency modulation (NLFM) signal into the design of an OFDM chirp waveform, a new OFDM-NLFM waveform with low peak auto-correlation sidelobe ratio (PASR) and peak cross-correlation ratio (PCCR) is obtained. IN-OFDM is the OFDM-NLFM waveform set currently with the lowest PASR and PCCR. Here we construct the optimization model of the OFDM-NLFM waveform set with the objective function being the maximum of the PASR and PCCR. Further, this paper proposes an OFDM-NLFM waveform set design algorithm inspired by alternating optimization. We implement the proposed algorithm by the alternate execution of two sub-algorithms. First, we keep both the sub-chirp sequence code matrix and sub-chirp rate plus and minus (PM) code matrix unchanged and use the particle swarm optimization (PSO) algorithm to obtain the optimal parameters of the NLFM signal’s time-frequency structure (NLFM parameters). Next, we keep current optimal NLFM parameters unchanged, and optimize the sub-chirp sequence code matrix and sub-chirp rate PM code matrix using the block coordinate descent (BCD) algorithm. The above two sub-algorithms are alternately executed until the objective function converges to the optimal solution. The results show that the PASR and PCCR of the obtained OFDM-NLFM waveform set are about 5 dB lower than that of the IN-OFDM.

The rapid development in bacterial resistance to many groups of known antibiotics forces the researchers to discover antibacterial drug candidates with previously unknown mechanisms of action, one of the most relevant being the inhibition of tRNA (Guanine37-N1)-methyltransferase (TrmD). The discovery of selective TrmD inhibitors in the series of carboxamide derivatives of thienopyrimidines became a background for further modification of the similar structures aimed at the development of promising antibacterial agents. As part of this research, we carried out the construction of heterocyclic hybrids bearing the moieties of thieno[2,3-d]pyrimidine and benzimidazole starting from 3,5-dimethyl-4-oxo-2-thioxo-1H-thieno[2,3-d]pyrimidine-6-carboxylic acid, which was used as the pivotal intermediate. The hybrid molecule of 6-(1H-benzimidazol-2-yl)-3,5-dimethyl-2-thioxo-1H-thieno[2,3-d]pyrimidin-4-one prepared via condensation of the carboxylic acid with ortho-phenylenediamine was further alkylated with aryl/hetaryl chloroacetamides and benzyl chloride to produce the series of S-alkyl derivatives. The results of molecular docking studies for the obtained series of S-alkyl benzimidazole-thienopyrimidines showed their high affinity to the TrmD isolated from the P. aeruginosa. The results of antimicrobial activity screening revealed the antimicrobial properties for all of the studied molecules against both Gram-positive and Gram-negative bacteria and the Candida albicans fungal strain. The highest antimicrobial activity was determined for 2-{[6-(1H-benzimidazol-2-yl)-3,5-dimethyl-4-oxo-3,4-dihydrothieno[2,3-d]pyrimidin-2-yl]thio}-N-(4-isopropylphenyl)acetamide, which also had the highest affinity to the TrmD inhibitor’s binding site according to the docking studies results.
Connecting into the Social Sustainability Effects of Infrastructure through China’s Digital Silk Road: Issues, Indices, and Indications
Authors: Blanchard Jean-Marc F. , Hooijmaaijers Bas
Published: November 2021

There is a heated debate about the social-sustainability implications of infrastructure. We engage this debate by delving into China’s Digital Silk Road (DSR), an important component of China’s infrastructure-centric Belt and Road Initiative (BRI). Optimists and pessimists have offered strong views about the DSR’s social-sustainability implications. Unfortunately, there is a dearth of analytical tools and in-depth studies which can be used to judge their competing arguments. In this article, we address these problems in two ways. First, we advance an original scheme for operationalizing social sustainability. Second, we use our framework to systematically analyze the DSR’s social-sustainability effects in Ethiopia, Malaysia, the United Arab Emirates, and Hungary. Our research indicates that much of the positive and negative commentary about the DSR’s social-sustainability implications is problematic. None of our cases show significant year-to-year changes in political or quality-of-life social-sustainability benchmarks. Indeed, our analysis indicates that analysts must pay close attention to the political and economic context to understand the social-sustainability patterns associated with DSR infrastructure. Finally, it suggests that the social-sustainability implications of DSR infrastructure are dependent on its scale and nature. These findings have ramifications for broader debates about the socioeconomic impact of infrastructure.

Published: November 2021

This study aims to (a) identify the relationship between travel motivation and popular media (mainly films or TV programs), (b) examine the relationship between destination images and popular media as an information source, and (c) investigate the influence of popular media on destination’s decision-making process. The relationship is focused on three aspects: motivation, destination image, and the decision-making process for tourists. This study employed a self-administered questionnaire survey. The questionnaire was composed of (i) respondents’ motivation and general information about their visit to the destination (Jeju Island in Korea), (ii) attributes of the film-induced tourism of their visit to the destination, and (iii) respondents’ socio-demographic elements. A correlation analysis and a standard multiple regression analysis were employed. The results discovered that there is a significant relationship (a) between a destination and popular media, (b) between destination image and popular media, and (c) between the decision-making process and popular media. The implications of this study can help destination marketers and managers build competitive strategies using the effective management of film-related tourist attraction sites to increase visitor numbers and ensure that a sustainable long-term relationship is encouraged between destinations and tourists.

Authors: Chandra Subhash , Jagdale Pravin , Medha Isha , Tiwari Ashwani , Bartoli Mattia , Nino Antonio , Olivito Fabrizio
Published: November 2021

Sulfamethoxazole (SMX) is a frequently used antibiotic for the treatment of urinary tract, respiratory, and intestinal infections and as a supplement in livestock or fishery farming to boost production. The release of SMX into the environment can lead to the development of antibiotic resistance among the microbial community, which can lead to frequent clinical infections. SMX removal from water is usually done through advanced treatment processes, such as adsorption, photocatalytic oxidation, and biodegradation. Among them, the advanced oxidation process using TiO2 and its composites is being widely used. TiO2 is a widely used photocatalyst; however, it has certain limitations, such as low visible light response and quick recombination of e−/h+ pairs. Integrating the biochar with TiO2 nanoparticles can overcome such limitations. The biochar-supported TiO2 composites showed a significant increase in the photocatalytic activities in the UV-visible range, which resulted in a substantial increase in the degradation of SMX in water. The present review has critically reviewed the methods of biochar TiO2 composite synthesis, the effect of biochar integration with the TiO2 on its physicochemical properties, and the chemical pathways through which the biochar/TiO2 composite degrades the SMX in water or aqueous solution. The degradation of SMX using photocatalysis can be considered a useful model, and the research studies presented in this review will allow extending this area of research on other types of similar pharmaceuticals or pollutants in general in the future.

Published: November 2021

Differences in the demographic and clinical characteristics of patients infected with the Alpha and Delta SARS-CoV-2 variants of concern in a large region of Southern Italy were assessed. Two cohorts of positive patients were compared. The Alpha group consisted of 11,135 subjects diagnosed between 21 March and 21 April 2021, and the Delta group consisted of 499 positive subjects diagnosed between 21 July and 21 August 2021. A descriptive and statistical analysis of the demographic and clinical characteristics of the two groups was performed. The proportion of patients with mild and moderate infections was significantly higher in the Delta than in the Alpha group (p < 0.001). In fully vaccinated patients, the proportion of symptomatic individuals was significantly higher in the Delta than in the Alpha group. The Delta group showed odds ratios of 3.08 (95% CI, 2.55–3.72) for symptomatic infection and 2.66 (95% CI, 1.76–3.94) for hospitalization. Improving COVID-19 vaccination rates is a priority, since infection with the SARS-CoV-2 Delta variant has a significant impact on patient outcomes. Additional targeted prevention strategies such as social distancing, the use of masks in indoor settings irrespective of vaccination status, and the use of a sanitary passport could be crucial to contain further spread of SARS-CoV-2 infection.

The article provides a retrospective analysis of the current state of the agro-industrial potential of the Autonomous Republic of Crimea. Prospects for development of the region’s agrarian economy are substantiated on the basis of identified structural transformations. In the process of research, the following methods were used: abstract-logical – to formulate conclusions; comparative analysis – to compare indicators and identify trends in their change; tabular – for a visual representation of the obtained research results; statistical – when analyzing the state of the agricultural economy of Crimea and its potential; monographic – detailing the current state and problems of the functioning of agriculture in the region; graphic – to illustrate the trends of the studied economic phenomena. The tendency of a significant decrease in the share of the agro-industrial complex in the aggregate gross regional product of Crimea and share of employed workers is revealed. It is proved that the main transformational imbalances in the practice of the agricultural economy functioning are: a large-scale reduction in the areas and volumes of production of moisture-dependent crops, the destruction of forage and rice industries, a steady trend of low crop yields and reduced livestock of animals. These factors led to a decrease in the production of food products in the region. The problematic issue is the aggravation of the situation with water supply and water use on the peninsula, as a result of which there was a tenfold reduction in the area of irrigated land. The factors that have a destructive effect on the efficiency of the functioning of the agricultural economy of Crimea are systematized.

It is proved that the assessment of the proposed indicators allows a comprehensive and more complete assessment of the nature management level and environmental friendliness of the enterprise.
Priestly playwright, secular priest: William Drury’s Latin and English drama
Authors: Shell Alison
Published: November 2021

This article examines the literary career of the secular priest William Drury, with an emphasis on his drama. The Latin plays which he wrote for performance at the English College in Douai are among the best-known English Catholic college dramas of the Stuart era; markedly different from the Jesuit drama which dominates the corpus of British Catholic college plays, they suggest conscious dissociation from that imaginative tradition. Hierarchomachia: or the Anti-Bishop, a satirical closet drama which intervenes in the controversy surrounding the legitimacy and extent of England’s Catholic episcopacy, can also be attributed to Drury. In both his Latin and English drama, Drury draws imaginative stimulus from his ideological opposition to Jesuits and other regulars. Yet his characteristic blend of didacticism and comedy, and his sympathy for the plight of all English Catholics—surely fomented by the death of his Jesuit brother in the notorious “Fatal Vesper”—point to broader priestly concerns.

The article deals with the information aspects of the nonlinear differential game “pursuit-evasion”. The mini- max quality criterion (the price of the game), mathematical models of the movement of the same type of players are set. The main problem that arises in the practical consideration of a nonlinear differential game is the solution of a boundary value problem. It is proved that: 1) a differential game can be represented as an envelope of a family of singular curves (“instantaneous solutions”) constructed from each of its points, 2) the control of the players can be found on this family. The method of constructing instant solutions is justified. The principle of information dualism in the differential game “pursuit-evasion” is proved. Its use facilitates the solution of information and computational problems that arise during the implementation of the game.

The analysis of the dynamics of the number of active nodes depending on the type of probability distributions of uptime and recovery time is carried out. The dependences of the mathematical expectation of the number of hyper-edges of certain types in the geometric hypergraph of a wireless computer network on the network operation time, on the radii of zones of reliable reception / transmission of a signal, on the ratio of the parameters of local recovery processes are obtained. The presentation of the results is accompanied by charts.

Based on a comparative analysis of the definitions of reliability and resistance, the article substantiates the possibility of using the probability of failure of radio-electronic equipment of an information system (REA IS) as an indicator of resistance to the effects of EMR. The interrelation of these definitions is shown and an analytical model is proposed for assessing the stability of equipment to the effects of a sequence of electromagnetic radiation. As an indicator of resistance, it is proposed to use the probability of failure of the REA during operation.

The article is devoted to the field of software development. The considered scientific contradiction lies in the fact that, on the one hand, the use of manual labor of a programmer is necessary in this area, and on the other hand, the presence of a human factor negatively affects the safety of the resulting code. To resolve the contradiction, it is proposed to use machine learning, which is traditionally used to solve the problem of classification, regression, search for anomalies, clustering, generalization and search for associations. It is shown that the majority of publications on this solution are of a private nature and do not cover the entire spectrum of possibilities. Various ways of automating the programming process using solutions for the specified machine learning problems are considered and substantiated. The demand for a system that combines such methods is indicated; Also, for the first time, its author’s definition is introduced: «Intelligent Programming Support System – a computer automated system based on artificial intelligence technologies, the purpose of which is to help developers of program code in the interests of reducing and simplifying manual labor, as well as increasing the safety of the final product». A comparative analysis of automation methods based on machine learning is given according to 8 criteria that this intelligent system must meet. The ways of further continuation of the research are indicated.

Projects for the development of the transport system of the Russian Federation involve the introduction of advanced optical technologies in the infrastructure of high-speed modern transport systems in the context of the implementation of un- manned maintenance technologies. The article presents the following areas of research carried out by the authors: — organization of high-speed super-long single-span trunk communication lines without intermediate allocation of digital channels and paths laid in areas with limited access by the maintenance personnel in areas with no infrastructure (underwater obstacles, mountainous terrain, desert and swampy areas). The authors of the article highlighted the main factors influencing the design features of high-speed ultra-long single-span communication lines; — application of photonic switching (PS) technology in high-speed backbone communication networks to ensure operational logical reconfiguration of channel structures and digital paths. Within the framework of this direction of research, the authors have proposed methods for calculating the probabilities of the occurrence of internal blockages in various structures of PS based on the use of the method of mathematical induction in order to synthesize PS structures of a given capacity; — development of effective technologies for remote monitoring of the health of transport infrastructure facilities using passive optical transmission lines. Within the framework of this line of research, the authors analyze the features of the physical prop- erties of optical fibers used as a distributed sensor on the basis of which an integrated system can be built that can measure various physical parameters, such as vibration, deformation, temperature and other parameters.

A commentary on: Reappropriation of Gendered Irish Sign Language in One Family
Authors: Dyson Mary
Published: November 2021

Barbara LeMaster’s article “Reappropriation of Gendered Irish Sign Language in One Family” in Visual Anthropology Review piqued my interest with its initial sentence: 

The native vocabularies of one segment of the Dublin deaf community (i.e., primarily women over 70 and men over 55) contain different signs for the majority of common lexical items examined (LeMaster 1990). 

From this I learned that there existed different female and male signs in Irish Sign Language. This intrigued me and led me to explore further, despite recognizing that I was probably out of my comfort zone. I would be addressing a topic of social history, through my lens of theoretical and empirical aspects of communication design. Curiously, I rejected a more comfortable choice of an article that uses an approach far more familiar to me: research analyzing the covers of introductory texts on cultural anthropology (Hammond et al., 2009). I am therefore acutely aware that the questions I ask about Irish Sign Language not only stem from another discipline, but also introduce different research methods. I also suspect that some of the issues I raise are covered elsewhere, either by LeMaster or by other researchers. This I regard as a positive sign of considerable overlap between our disciplines.

In the following commentary on LeMaster’s article, I start with a brief account of what I consider to be main themes within the article. This is not a comprehensive summary, but sets the scene for discussion points. I then propose some general differences in approach and emphasis between the disciplines of visual anthropology, as represented in this article, and communication design. Although I have situated myself within a particular sector of communication design (in the introduction), I have nonetheless tried to cover a wider field encompassing design practitioners and historians. From more general topics, I narrow down to specific areas that might inform, or be informed by, graphic communication research: the process of language standardization and dictionary design. The final section on signs moves us some distance from LeMaster’s study. However, personally, one of the most exciting aspects of research is forging links between apparently disparate areas of research, which might require a leap in the dark.
Developing Accurate Visual Conventions?
Authors: Van der Waarde Karel
Published: November 2021

Five articles about pictorial materials that were published in Visual Anthropology Review were read with an aim to compare the research approaches of anthropology and visual communication design. This text focuses on three themes in the five articles that relate to pictorial materials: processes, terminology, and the objectivity of visual evidence. Several questions and uncertainties are very similar in both disciplines. It might be beneficial for investigations into visual communication design practices to consider the level of detail, a critical theory base, and reflexive positions that form the basis for the five anthropology articles. Both disciplines need to look at terminology and investigate the motivations and impact of pictorial materials.
