This research focuses on the use of ontologies as formal knowledge bases for representing source code in automated systems.By creating an ontology that represents the concepts, relationships, and properties of source code elements, it becomes possible to capture and organize knowledge about the codebase. This enables various functional abilities such as automated code analysis and reasoning about code structure and behavior. The aim of this research is to verify the ability to use ontology as a formal knowledge base about source code in automated systems. A review of the recent articles showed that existing tools to work with ontologies does not provide direct functionality to convert the code into a knowledge, so the idea proposed in the article has novelty. The research explores the use of the Web Ontology Language (OWL) as the primary ontology representation language due to its expressiveness, reasoning capabilities, and compatibility with semantic web standards. The research proposes the creation of ontology representations for various code entities, with classes representing main entity types and individuals representing specific instances within the codebase. To validate the concept and demonstrate the expected results, a proof-of-concept system is built, consisting of a parsing client, a RESTful API for communication, and an ontology manager. The system utilizes libraries such as SwiftSyntax for parsing Swift code, Alamofire for HTTP communication, and OWL manipulation libraries (such as OWL-API and ONT-API) for working with ontologies. The system aims to extract knowledge from the source code, convert it into ontology entities and axioms, and reason over the ontology using a reasoner (such as HermiT). The research concludes that ontologies can effectively store knowledge about source code and enable various further manipulations on that knowledge. However, further investigation is needed to determine the optimal set of properties and entities that should be supported by the code ontology extraction system to infer more knowledge about the source code.

Published: October 2023

The paper considers the prediction of land value using LightGBM, Fast Tree, and Fast Forest machine learning methods. The training dataset is collected from the Internet and contains of 800 rows (in some cases there are data gaps for certain attributes). An overview of the problems of collecting such data is made. From the full dataset (D1), three additional ones were created: without data on land rent price (D2), without data on normative monetary assessment (NMA) (D3) and without data on rent price and NMA (D4). Using the LightGBM method has the best prediction results, but in some cases Fast Tree’s prediction quality is similar to LightGBM. Removing NMA data from the dataset improves the quality of prediction, because after calculations it turned out that there is no correlation between market value and NMA. Also, unlike real estate value prediction, gradient boosting methods provides better results. A correct prediction is defined as a prediction with no more than 10% error, which follow similar approaches in other researches. Depending on the dataset and the chosen method of machine learning, the quality of prediction ranges from 35% to 92% of correct predictions. The paper describes research’s limitations and possible ways to improve the quality of land price predictions for reviewed machine learning methods.

Published: October 2023

Objectives: To determine predictive factors associated with the onset of Wernicke encephalopathy (WE) and produce a decision tree predicting patients prone to developing WE.
Methods: Demographic, clinical, and laboratory data and the consultation notes of 314 inpatient alcohol use disorder consultation cases were collected. Receiver operative characteristic curve analysis was performed to identify the predictors of WE development.
Results: Of the patients with alcohol use disorder, 34.08% developed WE, and 43.93% of those were also diagnosed with hepatic encephalopathy. Delirium history was a predictive factor for patients with alcohol use disorder, with the highest statistical significance, and 54.8% of the patients with prior delirium history developed WE. Hemoglobin (Hb) levels <12.1 g/dL and alanine aminotransferase (PT) levels ≥25 IU/L were the next most significant predictive factors. For patients with alcohol use disorder with altered mental status, a Hb level of 14.4 g/dL was a predictive factor with the highest statistical significance, and 73.3% of patients with Hb levels <14.4 g/dL developed WE. Total bilirubin levels ≥1.1 mg/dL and C-reactive protein (CRP) ≥2.6 mg/dL were the next most significant predictive factors.
Conclusion: Assessing delirium history, Hb, and PT levels in patients with alcohol use disorder and Hb, total bilirubin, and CRP levels in patients with alcohol use disorder with altered mental status can help to evaluate the risk of developing WE.
The Image of the City in Chinese Cultural Tradition and Visual Practice: from the Middle Ages to the Early Modern Period
Authors: Kotlyar Eugeny
Published: October 2023

The article examines the problem of the artistic evolution of the image of the city in Chinese fine art. The focus of the authors’ attention is the study of the main stages of the development of the urban landscape genre. The purpose of the article is the analysis of the main stages of the development of the urban landscape genre in Chinese art, as well as the study of its structural formalization and the formation of the repertoire from the Middle Ages to the early modern period. The subject of the research is Chinese art history discourse. The works of Chinese fine art of historical periods were used.
The authors found out that the development of the urban landscape genre is connected with the general evolution of the Chinese cultural tradition and its visual forms. They are a constant factor influencing the formation of visual tradition.
The article defines two stages of development of the urban landscape genre paradigm. The first continues from the time of the emergence of permanent pictorial forms (X century). Later, during the period of the Song dynasty (XII–XIII centuries) and the period of the Ming dynasty (XIV–XVII centuries), visual culture involved the urban landscape and urban everyday practices in the general artistic space of painting. In the context of the evolution of art during the Qing dynasty (XVII–XIX centuries), the urban landscape is represented for the first time with the help of genre features. According to the authors, these signs should be presented in the form of a combination of three components: 1) urban architectural landscape; 2) representations of typical models of urban life; 3) reproduction of typical city "cultural heroes".
The authors prove that the evolution of the urban landscape genre at various stages of development is connected with the processes of self-awareness of Chinese art and the determination of the forms of its identity.

Published: October 2023

The article deals with a “myth” problem of Priamurye as a cross-border territory through the concept of Cosmo-psychologos (by G.D. Gachev). The paper emphasize Verticality/Horizontality dichotomy based on natural landscape of this territory inhabited by local peoples (Ulch, Nanai, Oroch, Udege, Evenks, Evens, Negidals), so that dichotomy can form specific “world image”. The authors cover basic mythologemes and symbols of Priamurye native peoples dealing with the image of Verticality (three-part world model, spirits and gods hierarchy, cosmogony order, mythological birds, the river, traditional dwelling, shamanic tree and cult trees, the mountain etc.) and emphasize the role of traditional shaman who is to deal with the Verticality. The authors examine the modern Priamurye myth`s eclecticism and weak structure having significant amount of borrowings, so it seems difficult to draw a strict borderline between “aboriginal” and “Russian” world images. The authors conclude on reasons why shamanism and modern shamanic practices can be popular nowadays.

Authors: Khaydarov M. M. , Kovalenko A. L. , Petrov A. Yu. , Khaidarova N. T.
Published: October 2023

With the help of literature data, the effectiveness of Cytoflavin inclusion in the treatment regimens for patients with psoriasis, microbial eczema, and rosacea in the period of exacerbation was analyzed based on the assessment of subjective and objective data of the DLQI (Dermatology Life Quality Index), WAM (Well-being, Activity, Mood), DISS (Dermatological Index of the Symptom Scale). It was revealed that, according to the results of testing before the start of treatment, all patients had mental disorders, which manifested in an increase in indicators on the DLQI and DISS scales and a decrease on the WAM scale. The reduction of clinical manifestations and the decrease in DISS (by 86.0%, (P≤0.05) for rosacea, by 83.0% (P≤0.01) for eczema) was found to be more pronounced after a course of therapy with the inclusion of Cytoflavin (2 tablets 2 times a day 30 minutes before meals, course — 25 days), compared with standard therapy. This had a positive effect on well-being (the value of the indicator increased by 63,9% for rosacea, by 66,0% for eczema, and 27.8% for psoriasis), activity (56,1% for rosacea, 66.1 % for eczema, and 22.1% for psoriasis), mood (51,9% for rosacea, 54.3% for eczema, and 23.7% for psoriasis), and improved quality of life: indicator DLQI decreased by 42,9% in rosacea, 62.4% in eczema, and 61.5% in psoriasis. Thus, the analysis of literature data made it possible to confirm that the inclusion of Cytoflavin in the treatment regimens for patients with the above-mentioned skin pathologies, comorbid with mental disorders, improves the effectiveness of basic therapy, which is manifested by a faster and more pronounced reduction in clinical manifestations and an increase in the quality of life of patients.

An autonomous car is a one-of-a-kind specimen in today's technology. It is an automatic system in which most of the duties that humans undertake in the car can be done automatically with minimum human supervision for road safety features. Moving automobile detections, on the other hand, are prone to more mistakes and can result in undesirable situations such as minor car wrecks. Moving vehicle identification is now done using high-speed cameras or LiDAR, for example, whereas self-driving cars are produced with deep learning, which requires much larger datasets. As a result, there may be greater space for improvement in the moving vehicle detection model. This research intends to create another moving car recognition model that uses multi-scale feature-based detection to improve the model's accuracy while also determining the maximum speed at which the model can detect moving objects. The recommended methodology was to create a lab-scale model that can be used as a guide for video and image capture on the lab-scale model, as well as the speed of the toy vehicles captured from the Arduino Uno machine before testing the car recognition model. According to the data, Multi-Scale Histogram of Oriented Gradient can recognize more objects than Histogram of Oriented Gradient with higher object identification accuracies and precision.

Published: October 2023

Rapid prototyping (RP) is a popular method for product development and design in medical industries. Endotracheal tube (ETT) incubation is a common problem when using medical equipment. Among the difficulties that surgeons face during surgical procedures are the misinsertion of an endotracheal tube into the oesophagus and extubation due to the patient's limited mobility. The aim of this work is to design an innovative endotracheal tube holding model. The survey was carried out in order to identify the most common ETT problems. As a result, quality functional deployment and product design and development methodologies were utilised to select the design for all of the ideas, which were designed based on the demands indicated by the consumers. The concept score matrix was used to evaluate the designs. As a result, concept A is selected as the final design. The overall score for each concept was calculated to discover which concept has the highest rating. Based on the results of the concept scoring and concept screening, concept A is the most likely to be produced. The concept meets the most demanding needs of the users. The selected design was then created on the Fused Deposition Modelling (FDM) machine.

In the present research work, a novel class of epoxy built hybrid combinations strengthened with E-Glass woven rowed mat and occupied with rice husk ash (RHA), wood dust ash (WDA) and a mixture of RHA & WDA has been developed and structural mechanical properties were determined and the results were matched with the non-filled composites. The studies on these composites reveal that the tensile strength (TS) of the composites is decreased by the escalation in weight percentage of the filler material and the rest of the mechanical properties were increased with the increase in weightiness proportion of RHA, WDA and RHAWDA. TOPSIS and VIKOR’S ranking methods are applied to know the best composite from 16 alternative composites having 6 attributes. From the results, the composite filled with RHA at 5 wt% is selected as the best composite based on mechanical characteristics. Water absorption behavior of the composites at various time intervals for RHA, WDA and RHAWDA filled hybrid composites has been studied and it is concluded that the composites occupied with RHA at 12.5 wt% have given the minimum water absorption rate (WA) compared to other filled composites immersed in distilled and mineral waters and the composite filled with WDA at 2.5 wt% has exhibited the minimum water absorption rate (WA) when it is immersed in ground water for 144 hours of a time interval. Based on the results of water absorption rate (WA) and mechanical characteristics (impact strength and Vickers hardness) the composites filled with RHA at 5 wt% and RHA at 12.5 wt% can be used for the manufacturing of roof sheets and water tanks.

In this paper, increased attempts are carried out to develop the deep neural networks to diagnose COVID-19 based on Chest X-Ray (CXR). This work introduces a new diagnostic system, utilizing different deep neural networks, InceptionV3, DenseNet121, ResNet50, VGG16 and MobileNetV2 models, to classify CXR images into healthy normal, pneumonia bacterial and COVID-19. Additionally, transfer learning and data augmentation techniques are utilized to solve the problem of scarcity of CXR images; hence the over-fitting of deep models will be avoided. The proposed end-to-end deep system is applied on the dataset sourced from COVID-19 lung CXR images from Kaggle and the IEEE8020 COVID-19 CXR dataset which is introduced by John Hopkins Hospital. The classification results reveal that diagnostic of CXR lung images by InceptionV3 provides the best results, with 98.87% accuracy, 98.88% area under the curve (AUC), 98.98% sensitivity, 98.79% precision, 97.99% F1- score and 1.4574 s computational time. Finally, the ensemble classifier with a voting strategy is proposed to boost the diagnosis performance using the multiple convolutional neural networks (CNNs) instead of one. The classification results are aggregated of each image using the voting technique. It is observed that the performance of the proposed ensemble classifiers with voting strategy reaches the state-of-art performance.

In an era marked by the rapidly growing levels of international trade and tourism, the accurate recognition of various currency notes has become a necessity. This paper presents research on an image processing technique for classifying the origin of currencies. Individuals are hardly distinguishing between different currencies from various countries. Therefore, it becomes necessary to develop an automated currency recognition system that helps in recognition notes easily, accurately and efficiency. The methodology consists of five stages, which are image acquisition, image pre-processing, feature extraction, classification, and, lastly, results and analysis. The currency image will be pre-processed in grayscale and split into 100x100 blocks at selected regions of interest (ROI) on the currency. Next, binary matrix image features and representations will be extracted. Lastly, the similarity percentage of the binary matrix will be calculated and compared with all currency image matrices. The highest similarity percentage will be chosen as the currency's origin. The proposed algorithm successfully classified the currency and improved the accuracy of currency classification, achieving a 93.4% accuracy rate from the experimental results. The proposed method could be useful for various applications, including financial institutions, security agencies, and automated currency processing machines.

Published: October 2023

A lot of focus has recently been placed on clinical decision support systems, that use advanced data mining methods to assist clinicians in making wise decisions. Along with increasing diagnosis accuracy, clinical decision support systems (CDSS) have the added benefit of speeding up diagnosis. Data security is crucial in this system. In this research, we offer EPPCD (Efficient and Privacy preserving Patient-centric Clinical Decision) support system to assist physicians in predicting illness risks of patients in a privacy-preserving manner. This system is proposed to solve the privacy difficulties present in the CDSS. The fine-grained access control enabled by the novel Double Encryption Ciphertext Policy Attribute-Based Encryption (DE-CPABE) technique is found to be a potential solution to this issue. In the proposed system, the past patients’ historical data are stored in cloud and can be used to train the hybrid Rotation Forest and AdaBoost classifier. Furthermore, extensive simulations used to evaluate performance show that our technology is capable of quickly and accurately determining a patient's disease risk while maintaining their privacy. The proposed system model is divided into five parties: Cloud Platform (CP), Trusted authority (TA), processing unit (PU), data provider (DP), and undiagnosed patient (PA).
Stress Classification Lines for Non-Standard Y-Tee Design in Piping System

All processes fluids in the oil and gas industry are generally transferred from one point to another via complex piping networks. The process temperature and the pressure of the fluids may vary between -21 °C to 816 °C and from atmospheric, 1.013 barg to 431 barg, respectively. Under these conditions, the entire piping networks are exposed to thermal expansion and contraction resulting in mechanical bending, potentially causing mechanical failures. The most common pipe fitting used in piping networks to divide the fluid flow into two different directions would be a standard equal tee which was designed in accordance with ASME B16.9. The equal tee, however, has distinctive flexibility characteristics compared to the pipe, which is well defined in ASME B31.3. These flexibility characteristics generate a stress intensification factor (SIF) through bending moment equations for beam-type element analysis for standard equal tee components. However, due to the limitation of SIF and flexibility characteristics for the non-standard pipe fittings, the stress evaluation could not be done using beam-type element analysis. When using finite element method (FEM) analysis, generally equivalent stresses (Von Mises or Tresca) or principal stresses would be evaluated depending on the stress categorization as explained in ASME codes and standards. In this paper, a stress evaluation method for non-standard Y-tee was developed and demonstrated against ASME VIII Div. 2 Part 5 requirement. The developed SCLs line for the non-standard Y-tee fittings provides the guides for stress assessment against design stress allowable. An optimum design for non-standard Y-tee is proposed at 45° and 60° crotch radii which resulted in lower stress value at SCL lines, hence improving the structural integrity.
