Published: April 2023

Abstract: The main objective of this article is to assist blind persons who have no human needs. Notably, anytime a blind person needs help, a hand is always there for them. The blind people's safety or ability to accomplish their goals isn't always guaranteed when they utilise this stick. The person may not feel any potential obstacles in their route if they use the stick. Notably, anytime a blind person needs help, a hand is always there for them. In any case, there is no assurance that using this stick will protect persons who are blind. The person using the support of the stick doesn't sense any obstructions in their way, despite there possibly being any. Therefore, if the obstruction is too great or dangerous, the people could suffer harm. In this study, a blind stick is designed and created to aid the blind and provide them with a clear path. The system consists of an ultrasonic sensor attached to the user's stick. As the user moves the stick forward, the ultrasonic sensor and Arduino Mega mounted to the stick try to detect any impediments in their way. When the sensor detects an obstruction, the output of the receiver triggers, and the microcontroller can notice this change because the output of the receiver acts as inputs to the microcontroller. This device recognises what is in front of the user and replies by vibrating or by posing a question. After that, the person can walk around without being afraid. This device will offer the best solution for a visually impaired person's issues.

Abstract: Lung cancer is classified histologically into small cell and non–small cell lung cancers. The most common symptoms of lung cancer are cough, dyspnoea, haemoptysis, and systemic symptoms such as weight loss and anorexia. High-risk patients who present with symptoms should undergo chest radiography. If a likely alternative diagnosis is not identified, computed tomography and possibly positron emission tomography should be performed. If suspicion for lung cancer is high, a diagnostic evaluation is warranted. The diagnostic evaluation has three simultaneous steps (tissue diagnosis, staging, and functional evaluation), all of which affect treatment planning and determination of prognosis. The main aim of this project is to find out the whether the person having lung cancer or not and having a chance of occurring Cancer in the future. We can done this process by using the CT(Computed Tomography) Scan Images of the lungs of affected Person. And it also identifies the given input CT Scan Image belongs to which person, which means that the image belongs to Normal person or it belongs to Cancer person or it belongs to the person who is having the chance of occurring cancer in the future, Which is also known as the PreMalignant Classification of images is done by using various CNN Algorithm

Authors: Shukla Ameya , Athreye Akul
Published: April 2023

Abstract: While drone delivery seemed ludicrous a few years ago, it is now a reality in many parts of the United States and throughout the world. Favourable development conditions, because of the FAA's more relaxed and transparent standards, as well as a rise in demand for autonomous last-mile delivery, are propelling drone delivery technology ahead. Consumers who have had the opportunity to experience drone delivery say they prefer the comfort, speed, and positive environmental effect of drone deliveries. Thus, it is very crucial to implement computer vision to increase the efficiency and safety of these delivery drones – and we believe that Jetson toolkit is a fantastic employable solution. Drones now have the processing power for improved object detection and tracking thanks to advances in computer vision and remote sensing. As a result, structured datasets can be used to teach deep learning-based unmanned aerial vehicles to detect objects while in surveillance mode. DNN-based drones have an important function: 3D object detection. After acquiring relevant data into the app, the camera with a trained computer vision model may scan an object utilising 3D object detection. This enables businesses to detect possible risks or things of concern in real time

Authors: Yurchenko E. V. , Timofeev M. N. , Margolin B. Z. , Galyatkin S. N.
Published: April 2023

The results of the study of mechanical properties and brittle fracture resistance (BFR) are presented for weld metal of WWER RPV performed by automatic arc welding with use welding wire Sv-15CrNiMoTiA and ceramic flux 48AF-71. Mechanical properties are determined on the basis of test results of tensile smooth round bar. BFR are determined from impact strength tests and fracture toughness tests. The anisotropy of mechanical properties and BFR is investigated by testing the specimens with different orientations. Tests are conducted for specimens of two orientations: first orientation corresponds to the position of the specimen, in which the fracture surface is perpendicular to the axis of the weld; second orientation corresponds fracture surface parallel to the axis of t he weld. It i s shown that the weld metal performed according to above mentioned technology has no anisotropy both in mechanical properties and in BFR. An explanation of the significant scatter of BFR on the basis of the results of metallographic studies is proposed. The obtained experimental results on mechanical properties for investigated weld metal allow to use tensile smooth round bar with 3 mm diameter with transverse orientation instead of specimens with 6 mm diameter with longitudinal orientation as the scale factor and anisotropy are negligible. The correlation dependence between the values of reference temperature T0 determined by the Master Curve method and reference temperature T100 determined by the Advanced Unified Curve method and the value of critical brittleness temperature TK0 for the studied weld metal in the initial state is established.
On the mechanism of chromium-nickel two-phase alloy strengthening and fracture
Authors: Adaskin A. M. , Butrim V. N. , Kubatkin V. S.
Published: April 2023

The mechanism of strengthening of a two-phase chromium-nickel alloy 65Cr-(31-35)Ni–Ti–V–W depends on the heat treatment mode: the lattice periods of the α-phase (alloy matrix is a solid solution of Ni in Cr) in the hardened and equilibrium conditions are almost the same; level of strength and ductility properties of alloy determines dispersion and amount of γ-soft nuclei released during heat treatment (solid solution of Cr in Ni), its hardness is less than that of α-phase. Quenching from single-phase area from 1250°C and tempering at 800−900°C provides a higher strength than annealed alloy and increases the start temperature of high temperature failure. The nature of the destruction depends on the temperature. The influence of γ-phase is manifested more significantly at temperatures below equicohesive.

Published: April 2023

Acute chest syndrome (ACS) is a common lung complication associated with
high morbidity and mortality in children with sickle cell disease. The
role of fine particulate matter (PM ) exposure in
admissions for ACS is limited. We assessed residential level PM
exposure in a case-crossover study of 503 patients
admitted to Texas Children’s Hospital between 2010 and 2019 in Houston,
TX. We examined whether short-term PM exposure is
associated with increased odds of hospitalizations for ACS and found no
association between PM exposures in the week
proceeding an ACS-related admission. However, larger studies are needed
to confirm or refute this finding.
Non-contact Voltage Measurement System for Low-Voltage Power-Line
Authors: Su Huafeng
Published: April 2023

In this paper, a non-contact measurement method of the power line
voltage based on capacitive coupling principle is proposed, which
realizes the reliable measurement of line voltage waveform. Firstly, the
basic principle of the non-contact voltage measurement method is
introduced in this paper, which mainly includes self-calibration and
online measurement of the sensor. The high frequency voltage signal is
injected into the capacitive coupling network of the sensor to implement
the self-calibration of the sensor ratio. Then, the digital integration
method is used to integrate the output signal of the sensor to achieve
the measurement of the line voltage waveform. Secondly, the non-contact
voltage sensor prototype and the corresponding signal processing circuit
are designed. Finally, the test platform of line voltage measurement is
built, and the measurement test of 220V/50Hz line voltage waveform is
carried out. The test results show that the relative amplitude error of
the voltage measured by the sensor is less than 1.5%, the maximum phase
error is less than 2°, and the linearity is better than 0.5%.
Inferring hillslope groundwater recharge ratios from the storage-discharge relation
Authors: Dralle David N , Hahm W. Jesse , Rempe Daniella
Published: April 2023

Accurate observation of hillslope groundwater storage and instantaneous
recharge remains difficult due to limited monitoring and the complexity
of mountainous landscapes. We introduce a novel storage-discharge method
to estimate hillslope recharge and the recharge ratio—the fraction of
precipitation that recharges groundwater. The method, which relies on
streamflow data, is corroborated by independent measurements of water
storage dynamics inside the Rivendell experimental hillslope at the Eel
River Critical Zone Observatory, California USA. We find that
along-hillslope patterns in bedrock weathering and plant-driven storage
dynamics govern the seasonal evolution of recharge ratios. Thinner
weathering profiles and smaller root-zone storage deficits near-channel
are replenished before larger ridge-top deficits. Consequently,
precipitation progressively activates groundwater from channel to
divide, with an attendant increase in recharge ratios throughout the wet
season. Our novel approach and process observations offer valuable
insights into controls on groundwater recharge, enhancing our
understanding of a critical flux in the hydrologic cycle.

In recent years, Particle Swarm Optimization (PSO) has been integrated with machine learning algorithms, such as deep learning, to create powerful hybrid methods that can tackle complex optimization problems more effectively. In the domain of oil and gas reservoir management, underground pressure management is crucial to maximize the yield and efficiency of the reservoir. However, the heterogeneity of the reservoir, along with uncertainties in its properties, makes pressure management a complex and challenging task. To address this issue, researchers have proposed Physics-Informed Deep Learning (PIDL) techniques that incorporate domain-specific knowledge, such as the governing physical equations, into the deep learning framework. Particle Swarm Optimized-Physics-Informed Deep Learning (PSO-PIDL) is a novel hybrid approach that combines PSO with PIDL to optimize the pressure management of heterogeneous oil and gas underground reservoirs. In this approach, the PSO algorithm is used to find the optimal solution for the PIDL-based model that incorporates the governing physical equations of the reservoir. PSO-PIDL can effectively handle the uncertainties and heterogeneity of the reservoir, while also incorporating the physical constraints of the problem. Overall, PSO-PIDL is a promising approach for optimizing the pressure management of oil and gas reservoirs. It can help reduce the operational costs and improve the efficiency of the reservoir, while also ensuring the sustainable use of natural resources.

Authors: Tymofieiev Oleksii , Fesenko Ievgen , Cherniak Olha , Serha Olena
Published: April 2023

Background: Mandibular osteomyelitis is commonly associated with invasive surgery and sequestrectomy. Here, we report a unique case in which it was possible to choose minimally invasive treatment during the exacerbation of osteomyelitis at the stage of sequestrectomy owing to the use of and correct assessment with ultrasonography (USG). This report aimed to present wide possibilities of USG for accurate diagnosis and minimally invasive management of chronic osteomyelitis.
Case Presentation: A 50-year-old woman presented with significant swelling in the left masseteric region, trismus, and severe pain in the area of a previously extracted lower third molar. The imaging protocol included panoramic radiography, USG, and cone-beam computed tomography. Using USG, it was possible to identify the intermediate stage of abscess/phlegmon formation in the masseteric area, which would require an extraoral incision to drain the purulent focus.
Conclusion: USG allows oral and maxillofacial surgeons to obtain a precise understanding of the condition of the tissues (e.g., bone surface, masseter muscle, subcutaneous tissue) and pathologic changes (e.g., periosteal reaction, bony defects) due to purulent processes in the area of the lateral mandibular ramus surface and surrounding soft tissues. The presence of purulent material and its motion on sonopalpation can be clearly identified using USG. Therefore, it is possible to plan for a less invasive surgical strategy.

Heuristic assessment of service quality: case of mobile communication operators
Authors: Nikulin Vladimir , Afonin Viktor Vasil'evich
Published: April 2023

A heuristic approach is proposed and considered in assessing the quality of information services on the example of mobile operators. The characteristics of the services of mobile operators can be divided into positive and negative. The former characteristics are directly proportional to the preferred choice of mobile communication users, and the latter are inversely proportional. For example, ceteris paribus, preference is given to a lower cost for the use

of mobile communications. The existing characteristics of the services of telecom operators are displayed in the tables in numerical terms of the corresponding dimension. Every mobile operator has such reporting spreadsheets, which are usually available in the Internet. In this regard, there arises a problem of determining a more preferable operator by given numerical values of the characteristics of services. In the proposed work, there has been made an attempt to determine the quality of mobile communications based on statistical indicators and input quality markers determined on the basis of heuristic assumptions. Bringing the numerical values of the characteristics of communication services to relative units determines the arithmetic average level of each of the characteristics of mobile communication services. According to this average level, generalized markers are assigned that characterize the quality of the services provided by the corresponding mobile operators. Packing the generated numeric markers into a container makes it possible to rank mobile operators by the values of quality markers. It helps to determine which of the telecom operators will be more preferable for the user.

One of the key tasks of managing contracts with university faculty (UF) is to determine the optimal term

of contract. In this regard, it is of scientific and practical interest to develop an effective mechanism of decision-making on the terms of the contracts with the UF. The competition for the positions of UF is held by the collegiate body for managing the personnel policy of the university called personnel commission (PC). The decision on the terms of the contract is made, according to the key performance indicators (KPIs) of UF activities for a certain time period. PC members have opportunity, in case the teacher fails to meet all the required KPIs, to recommend a longer contract term for a teacher, guided by other (alternative) KPIs. Since this approach is applied selectively and often without a reasoned justification for the position of PC members, the UF perceives it as a manifestation of manipulation on the part of the PC when deciding on the term of the contract. To solve this problem, it is proposed to use a non-manipulative mechanism of decision-making on the terms of contracts with the UF. To implement the proposed mechanism, a machine learning tool is used, which generates a forecast for the implementation of an alternative KPI by the teacher. The source of data for forecasting is the teacher's passive digital footprint, which makes it possible to ensure the completeness and veracity of information about his/her scientific and pedagogical activities. Based on the forecast obtained, the PC makes a reasonable and transparent decision on the term of the contract with the teacher. Using the proposed mechanism will reduce the negative im-pact of the effect of manipulation on the decision-making process of the PC on the terms of contracts with the UF of the university and hence to ensure an increase their efficiency.
Studying WebAssembly and comparison of its performance with JavaScript

Over the long history of the Internet, JavaScript has been the primary programming language in web development. Because of its simple syntax and support in all popular browsers, the language has gained popularity among the developers. However, as computer power and user demands evolved, simple sites turned into the web applications that are full-fledged analogues of the desktop applications. As capabilities grew, so did the performance requirements of such programs. Browser engines have developed ways to optimize the code they run, and intense competition between browsers has contributed to a qualitative increase in performance. Despite all the ways to increase the speed of execution of JavaScript code, the main stopping factor was the dynamic typing of the language. Because of dynamic typing, the browser engine needs to check each time the program is executed whether the variable is an integer, a float, or any other valid type. Thus, each JavaScript instruction has to go through several type checks and conversions, which slows down the execution. This led to the idea of using languages with strict typing, which could compensate for this drawback. But the browser engines cannot execute the code of other languages, that is why there appeared the technology WebAssembly. It allows writing code in languages with static typing, and then parses it into

a more native and machine-readable format, which speeds up execution of programs compared to JavaScript. The technology is cross-platform and supports the main programming languages: C++, C, Java, C#. WebAssembly is also implemented using JavaScript, which allows to use the concise JavaScript syntax and computing power of WebAssembly together.
ПИТАННЯ ЛІТЕРАТУРОЗНАВСТВА В «ЩОДЕННИКАХ ІВАНА ЧЕНДЕЯ»
Authors: Ференц Надія
Published: April 2023

У статті досліджується питання літературознавства у щоденникових записах І. Чендея. Зроблено аналіз його висловлювань про основні функції художньої літератури, її національну своєрідність, специфіку, місце серед інших видів мистецтва. Значна увага приділена судженням про сприйняття художнього твору читачем, рекомендаціям неодноразово перечитувати високохудожні тексти, вихованню естетичних смаків, критиці вульгарно-соціологічних під- ходів до мистецтва. І. Чендей підкреслював, що насолоджуватися мистецтвом може лише мистецьки вихована людина. Розглядаються тлумачення І. Чендеєм таланту, природної обдарованості, характеризуються складники таланту, зокрема працелюбність, адже велике мистецтво завжди супроводжувала велика праця, здатність відчувати силу і красу слова, чути його мелодію і звук, бачити барви і тони, уміння проникати у таємничий світ людської душі, давати об’єктивну оцінку складним явищам і процесам, у простому, незначному розгледіти непросте і велике. Згадуються критичні судження письменника про бездарність і графоманство. Серед бездар і графоманів таланту, за спостережен- ням І. Чендея, «скрутно і сутужно».

Приділяється увага таємницям художньої творчості, творчому процесу, який сповнений напруженням, мобілі- зацією сил і водночас великою радістю. Аналізуються думки І. Чендея про свободу творчості, відсутність права на художнє самовиявлення, «окови регламентів», на думку письменника, шкодять мистецтву, знищують таланти. Пору- шується питання про літературну критику, яка повинна піднімати письменника, вчити читача бачити прекрасне, умін- ню насолоджуватися змістом і формою художнього твору. Акцентовано, що літературний критик, як і письменник, по- винен бути чутливо-емоційною людиною, уміти захоплюватися усім талановитим. За словами І. Чендея, критика – не прокурор і не сектор нагородження відзнаками.
СЛОВОТВОРЧА СЕМАНТИКА ДЕНУМЕРАТИВІВ У КОГНІТОЛОГІЧНОМУ ВИМІРІ: ЛОГІЧНІ ПРОПОЗИЦІЇ
Authors: Костриба Ольга
Published: April 2023

Актуальною проблемою дериватології є аналіз її когнітивного вияву. Здебільшого об’єктом таких до- сліджень є словотвірні гнізда, які з позиції когнітивізму розглядають як фрейм-структури, – одиниці, що акумулюють ментальні знання людини, підводять їх під певні рубрики людського досвіду, проєктуючи на мовний рівень шляхом застосування словотворчих засобів.

Новий вектор досліджень, зокрема у відчислівниковому словотворенні, становить з’ясування лінгвокогнітоло- гічного аспекту словотворчої семантики крізь призму фреймової організації дериватів. Виявлення когнітивної природи словотвірних значень доповнює здобутки ономасіологічної дериватології. Розгляд мотивувального лексико-семантич- ного варіанта як одного з компонентів структурної експлікації певного знання – субфрейму в межах фрейму, а також дериваційно спроможної семи як вербалізованого слота ‒ сприяє доповненню надбань семантичного словотвору.

Мета дослідження – у межах фрейм-структур змоделювати когнітивний вияв словотворчої семантики денуме- ративів, яка оперта на логічні пропозиції. Для досягнення мети слід розв’язати такі завдання: встановити словотворчу семантику похідних із модифікаційним і транспозиційним типами деривації; обґрунтувати когнітивне формування мутантів та транспозитів як мисленнєву двокомпоненту операцію; змоделювати когнітивну природу відчислівникових утворень Л-пропозиційного типу.

Когнітивне моделювання словотворчої семантики денумеративів (утворень безпосередньо та опосередковано виведених від вершинного конституента словотвірного гнізда) дало змогу виявити тематику ментального рівня, за якою об’єднуються похідні слова в межах фрейму, більше того – словотвірні значення згруповуються за когнітивним змістом. З’ясовано типи логічних пропозицій та актантне наповнення пропозицій денумеративів із прирощеннями на рівні поширювачів.
