UAS Flight Path Planning: A Comparative Analysis of Diverse Use Cases and Approaches
Authors: Debus Paul , Rodehorst Volker
Published: June 2024

Abstract. Uncrewed aircraft systems (UAS), also known as drones, have become increasingly popular in various applications due to their ability to access remote or challenging locations. A crucial aspect of UAS operations is flight path planning, which determines the trajectory the aircraft takes to achieve its mission objectives. However, the diverse use cases of UAS demand different planning approaches tailored to their specific requirements. This paper presents an overview over current research in UAS flight path planning and proposes a categorization of use cases based on their distinct goals and considerations. The terminology differentiates the goals of tasks between navigation-centric and data acquisition and also considers their context, domain, perspective, and sensors. We analyze existing approaches with a focus on UAS flight path planning for data acquisition using cameras, highlighting their strengths and limitations. This structured overview facilitates the understanding of the diverse landscape of UAS flight path planning and paves the way for the development of more targeted and effective solutions for various applications and their use cases. The analysis shows, that the term ”UAS flight path planning” is currently used in a variety of distinct use cases with diverging requirements, so a unified terminology should be established for clear communication.

Authors: El Yamani Siham , Hajji Rafika , Billen Roland , Arroyo Ohori Ken , van der Vaart Jasper , Hakim Amir , Stoter Jantien
Published: June 2024

Abstract. This paper introduces Property Valuation Application Domain Extension (ADE) within CityGML 3.0, aiming to integrate relevant indoor and outdoor 3D variables (cost estimation, view quality, etc.) for accurate property valuation. Current models lack the necessary features for this specific application. Leveraging IFC data for indoor elements, this ADE extends CityGML, addressing the existing gap. This paper identifies and categorizes data requirements, leading to the conceptualization and development of the model. By enriching CityGML 3.0 with IFC data, the approach introduces new features like the "Property Unit" to ensure adaptability across diverse valuation scenarios. Despite encountering data integrability challenges, we here commit to refining the model and overcoming these obstacles. A preliminary implementation using CityJSON demonstrates successful integration and paves the way for future implementation. These include developing an API platform and establishing an official repository to facilitate practical usability and scalability. This research significantly contributes to advancing property valuation processes by providing accurate valuations for stakeholders and promoting the use of 3D urban data in domain-specific extensions.

Published: June 2024

Abstract. Digital Twins are realistic digital representations of the physical world, frequently characterised by a two way link between digital and physical. Originating in manufacturing, they are now expanding to city and national scales. In this paper we explore connections between Geographic Information Science and National Digital Twins. Six different viewpoints and perspectives are presented on the topic, highlighting the importance of: geospatial data engineering; metadata engineering; standards; challenges facing mapping agencies; governance and public values; and a ”reality check” that explores the gaps between what is required and what can currently be achieved. We present 22 recommendations and summarise the findings by presenting a high level research agenda to enable better understanding and articulation of the link between the two.
Enhancing Reinforced Concrete Bridge Health Monitoring: A Case Study on the Integration of InSAR, GPR, and LiDAR within 3D GIS Environment
Authors: Elseicy Ahmed , Solla Mercedes , Balado Jesús , Alonso-Díaz Alex , Rodríguez Juan Luis
Published: June 2024

Abstract. This work presents a preliminary case study on assessing reinforced concrete pedestrian bridge conditions in A Coruña (Galicia, Spain), employing a novel integration of non-destructive testing (NDT) technologies. The research aims to refine the health monitoring process of pedestrian bridges by adopting a top-down approach, leveraging the data-fusion concept to enhance the analysis of structural defects. A data-fusion methodology that integrates interferometric synthetic aperture radar (InSAR), ground penetrating radar (GPR), and light detection and range (LiDAR) technologies is introduced. Then, the data are visualized within a 3D Geographical Information System (GIS) environment. The MT-InSAR technique is used at the network level to identify bridges requiring detailed inspections. Subsequently, selected bridges undergo thorough examinations using GPR and LiDAR technologies from fieldwork between 2021 and 2023. A comparative analysis of three different LiDAR devices and two GPR setups is conducted to evaluate their effectiveness in capturing detailed structural data. The study also explores the integration challenges and solutions for combining diverse data formats and the possibility of using advanced digital technologies, such as Building Information Modelling (BIM), to facilitate a seamless transition from traditional NDT approaches to a digitized, model-based inspection framework. The findings highlight the advantages of each NDT method, address specific data acquisition challenges, and propose strategies for overcoming issues related to data integration, visualization, and the accuracy of spatial localization. Integrating these NDT technologies within a georeferenced 3D GIS environment facilitates a detailed understanding of the bridge's condition and enhances decision-making processes for maintenance and rehabilitation efforts.
CadaSPACE: A Cloud Based Platform for a low - cost 3D visualization of property rights available in a 2D cadastral registry. An example for urban multi – storey buildings
Authors: Andritsou Dimitra , Potsiou Chryssy
Published: June 2024

Abstract. This paper presents a methodology for a low – cost 3D visualization of property rights in multi – storey urban buildings using available and other relevant open geometric and legal data. An online, free platform is created, named “CadaSPACE”, to support the homogenous visualization of volumetric property units and open property rights included in 2D cadaster. The platform is directly interconnected with open – access pages such as the National Cadastral Portal, Autodesk Online Viewer, Tandem, Google Earth and Online 3D Viewer. It offers a wide range of statistical tools such as tables and diagrams to present, filter and manage the sematic information of the 3D property volumes. An application is presented for the Greek Cadaster. Legal information about the property rights is collected from the open - access cadastral records; building footprints are digitized on the available Orthophotos; architectural floor plans of each individual property unit are either taken from the documents included in the electronic building identity records (under construction) or are provided by the owners, and an approximate BIM (Building Information Model) is created for each building using additional approximate geometric information derived from Google Earth Pro and Streetview. The 3D property units are modelled and visualized as volumes. The whole 3D neighborhood model is uploaded online for further categorization and management through various visual and semantic filters. Considerations for further legal and technical improvements are given towards the implementation of the proposed methodology.

Authors: Bertolini Luca , Giorgadze Inga Maria , Vahdatikhaki Faridaddin , D’Amico Fabrizio
Published: June 2024

Abstract. This paper addresses the challenge of managing and maintaining road pavements effectively throughout their lifecycle. Emphasizing the need for a cohesive data collection and handling approach, the paper highlights the vulnerability caused by the absence of a structured information system, resulting in reworks, information loss, and misinterpretation of collected data. A unified data handling and collection structure, introducing the concept of a pavement Digital Twin through a standardized data structure is presented. The Digital Twin aims to integrate information regarding pavement failures, with the future aim of predicting deterioration and facilitating informed decision-making in management and maintenance interventions. Complexities in pavement failures, categorized into surface and subsurface modes, prompt the necessity for a reliable classification and representation system. The proposed methodology introduces a grid of cells for surface failures and three-dimensional voxels for subsurface failures, providing a structured approach for data integration throughout the pavement's lifecycle. An approach for the semantic representation of pavement distresses is also presented. The proposed methodology stresses the importance of scalability and flexibility in data storage, forming the basis for a comprehensive Digital Twin of road pavements. Finally, through the use of multiple pavement failure datasets, the methodology is shown to have a high potential in providing a structure for comprehensive management of road data.
CITYTWIN – AI-based Decision Support System for Semantic Search and Analysis of Location-based Information for Urban and Site Planning
Authors: Buchmann Oliver , Siegmund Maik , Kaden Robert , Iden Frank
Published: June 2024

Abstract. The development of a knowledge-based decision support system for the evaluation and planning of location and urban development concepts was implemented. In order to achieve this goal, cross-domain ontologies were developed for interdisciplinary databases, which are then mapped in semantic networks. The exponential growth in computing power in the hardware sector alone can no longer solve this problem, but at the same time enables the application of new methods for storing and evaluating data. Essentially, it is no longer just about the digital recording of object properties in conventional databases, but also about the digital representation of their significance for specific questions and the linking of meanings across the boundaries of specialist domains. This information is stored in a multimedia knowledge base, together with the methods and rules for its use and the evaluations and decisions based on it. The motivation for this project is the rapidly growing amount of data, which extends across ever new specialist domains and can no longer be sufficiently integrated into the decision-making of experts using conventional methods of knowledge acquisition. After determining this data, it was linked to a georeferencing. Within the framework of the project, documents were analyzed with the help of AI and examined for semantic text corpora. This data was georeferenced. Various algorithms were used to accomplish this task, including TF-IDF, TextRank and Word2Vec.
Determination of the shear wave velocity structure of substations by the HVSR inversion method using broadband and strong ground motion earthquake data in the Lake Van region, eastern Türkiye
Authors: Akkaya İsmail , Alkan Hamdi
Published: June 2024

In this research, the horizontal-to-vertical spectral ratio analysis and the Monte-Carlo inversion algorithm are applied to calculate the substations shear wave velocity structure beneath the Lake Van region. To discover the variation of shear wave velocity, the local earthquakes recorded on 15 strong ground motions and 14 broadband stations, located on dissimilar geological units, are used. The most important aim of this investigation is to reveal the geological structure and bedrock depths beneath each station. For this purpose, two-dimensional cross-sections are generated from velocity models in different directions. The average bedrock depth variation is determined at 10 m and 250 m as a result of the horizontal-to-vertical spectral ratio inversions at the earthquake stations in the region. The deepest bedrock depths are calculated at the earthquake stations close to the settlements in the study area. These depth variations are interpreted as the local site effects of possible destructive and big earthquakes that may be a factor increasing the damage ratio in these regions.

Published: June 2024

Based on the ERA5 reanalysis data for the period 1979-2021, the authors have quantified the seasonal and regional connections between significant wave heights and changes in cyclone activity in the atmosphere of the Northern Hemisphere. The contribution of extratropical cyclones to the formation of the corresponding features and variations of sea waves is evaluated. The maxima of the extreme sea wave occurrence frequency in winter and summer corresponds to sea areas with an increased frequency of cyclones, in particular, over the Pacific and Atlantic oceans. It has been found that the contribution of extratropical cyclones to the generation of significant wave heights reaches 70% in winter and 50% in summer. The largest contribution is associated with intense cyclones: 90% in winter and 40% in summer.

Published: June 2024

A method for detecting leads in the ice of the Arctic seas from satellite images of the visible range is presented. It is shown that sea ice leads are formed under the influence of dynamic processes in the ice cover, such as convergence, drift, and deformation of sea ice, as well as during the interaction of drifting ice with icebergs that have gone aground. The method for identifying sea ice leads is based on the use of artificial intelligence. To analyze the Landsat-8 satellite imagery, a convolutional neural network (U-Net architecture) was used. The method was tested using the satellite images of the visible spectral range that were obtained for the Laptev Sea. The results showed that the lead detection accuracy was above 80%. The method of the minimum rotated rectangle surrounding the polygon was used to determine the geometric parameters of the leads (length, width, inflection points).

Authors: Jo Seon Beom , Kim Hyun Ju , Ahn Sun Tae , Oh Mi Mi
Published: June 2024

Purpose: Previous studies have simply confirmed recurrence of acute cystitis negatively affects a patient’s psychological state. This study was performed to assess the impact of the recurrence of urinary tract infections on anxiety and depression and further assess whether there is a correlation between the number of recurrences and the degree of anxiety and depression.Methods: This cross-sectional study enrolled patients with recurrent cystitis who visited a tertiary care center between April 2018 and June 2022. For eligible patients, depression and anxiety were assessed by the Patient Health Questionnaire-9 and State-Trait Anxiety Inventory. Among the clinical characteristics, factors that independently affected the degree of depression and anxiety were analyzed. Additionally, the relationship between the level of anxiety, depression, and the number of recurrent cystitis was assessed.Results: A total of 112 female patients with recurrent cystitis were enrolled in this study. The proportion of patients with depression (moderate, 8%; severe, 0%) was relatively low compared with that of patients with anxiety (moderate, 22.3%; severe, 68.8%). Multivariate regression analysis showed that more recurrent episodes were significantly associated with higher anxiety scores (P<0.001). It was confirmed that longer disease duration is associated with higher depression scores (P=0.031). Additionally, there was a positive correlation between the number of recurrences and State-Trait Anxiety Inventory and Patient Health Questionnaire-9 scores (r=0.362, P<0.001 and r=0.248, P=0.009, respectively).Conclusions: Our study reveals that recurrent cystitis notably increases patients’ anxiety, correlating with the frequency of recurrences. Disease duration is also linked to depression. These findings emphasize the importance of preventing urinary tract infection recurrences to reduce psychological complications. To reinforce these results, larger cohort studies are necessary.
Can Urinary Bladder Innervation Be Restored After Outlet Obstruction and Denervation?
Authors: Uvelius Bengt , Andersson Karl-Erik
Published: June 2024

Transurethral resection of the prostate, or other methods to decrease outlet resistance usually leads to relief of symptoms in patients with bladder outlet obstruction (BOO). If symptoms of underactivity persist after normalization of outflow conditions, treatment options are limited. In this review, we hypothesize, based on results from basic research, what might become treatment options for such patients in the future. The primary local treatment will still aim at reducing outlet obstruction. We speculate that local secondary treatment in the future might include transplantation of stem cells or mature bladder ganglion cells into the bladder wall. There has been some success in transplanting ganglion cells into the rat bladder. The ganglion cells will sprout into the surrounding tissue but functional connections between the axons of the transplanted neurons, and the detrusor smooth muscle have so far not been demonstrated. Neurotrophins or neurotrimin might be injected into the bladder wall to increase the sprouting of existing or transplanted neurons. Stem cell transplantation has been performed and improves detrusor function, but it has so far, been difficult to demonstrate transplanted stem cells. BOO, persisting detrusor underactivity, and decreased nerve density are often combined with inflammatory activity of the lower urinary tract. NLR family pyrin domain containing 3 (NLRP3) and its messenger RNA (mRNA) as well as cyclooxygenase-2 (Cox-2) mRNA are increased in obstructed bladders. Systemic treatment with the NLRP3 inhibitor glyburide normalized nerve density in rat bladder, and, to some extent, bladder function. It is unclear whether Cox-2 is involved in the decreased nerve density following obstruction, but Cox-2 mRNA increases 5-fold in obstructed bladder. Future therapy against bladder underactivity remaining following relief of obstruction includes either systemic treatment, perhaps by anti-inflammatory drugs, or local treatment by injection of stem cells, mature ganglion cells, and/or neurotrophins or neurotrimin into the bladder wall.

Published: June 2024

Bladder cancer (BCa) is the most common malignancy of the urinary system. It has a high recurrence rate and requires longterm follow-up. Significant advances in BCa research have been made in recent years; however, the initial diagnosis and follow-up of BCa relies on cystoscopy, which is an invasive and expensive procedure. Over the past decade, liquid biopsies (e.g., blood and urine) have proven to be highly efficient methods for the discovery of BCa biomarkers. This noninvasive sampling method is used to analyze unique tumor components released into body fluids and enables serial sampling and longitudinal monitoring of tumor progression. Several liquid biopsy biomarkers have been studied extensively and have shown promising results in the clinical applications of BCa, including early detection, microscopic residual disease detection, recurrence prediction, and treatment response. Therefore, this review aims to provide an update on various new liquid biopsy markers and the advantages and current limitations of liquid biopsy in the diagnosis of BCa.
Triffin Paradox in 21 Century
Authors:   Kutaisi University, Khiodasheli Mirza
Published: June 2024

This article presents a fresh perspective on the Triffin Paradox, a concept introduced by economist Robert Triffin in the mid-20th century that continues to have a significant impact on global financial systems and policies. Despite the passage of time and the evolution of the economy, the fundamental principles of the Triffin Paradox remain relevant in today's financial discussions. The paper provides a thorough analysis of the ongoing relevance of the Triffin Paradox in the modern global economy. It draws upon historical context, theoretical frameworks, and empirical evidence to shed light on how the paradox continues to manifest itself in the current financial landscape. Specifically, it explores how the dominance of the U.S. dollar as the world's primary reserve currency perpetuates structural imbalances and systemic vulnerabilities, echoing the concerns raised by Triffin. Moreover, the paper delves into the implications of the Triffin Paradox for various stakeholders, including policymakers and central banks. It examines the challenges posed by the pursuit of domestic monetary policy objectives in an interconnected world, where the stability of the global financial system relies heavily on the stability of the reserve currency issuer. Additionally, the paper explores potential strategies for mitigating the risks associated with the Triffin Paradox and fostering a more sustainable international monetary order. By integrating insights from economics, finance, and international relations, this paper contributes to a deeper understanding of the Triffin Paradox and its enduring significance in shaping contemporary financial dynamics. It emphasizes the need for policymakers and stakeholders to address the inherent structural tensions in the global monetary system, with the goal of promoting financial stability, economic resilience, and inclusive prosperity worldwide.

В работе проведена оценка ресурса горячего упрочнения штамповой стали с регулируемым аустенитным превращением при эксплуатации. Для этого осуществляли деформационно-термическую обработку образцов по схеме сжатия, включающую этап предварительного горячего упрочнения (в интервале 450–750 °С) и этап длительной (девять циклов с истинной деформацией около 0,02 за цикл) горячей деформации (при 750 °С). Установлено, что в процессе длительной горячей деформации относительная величина разупрочнения образца составляет всего около 8%. Полученные результаты позволяют прогнозировать стабильную работу штампового инструмента из стали с регулируемым аустенитным превращением при эксплуатации при температурах 450–750 °С.

In this paper, an evaluation of the resource of hot hardening of die steel with regulated austenitic transformation during exploitation (RATE) was carried out. For this purpose, the thermomechanical treatment of the samples was carried out according to the compression scheme, which consisted of the stage of preliminary hot hardening (in the range of 450–750 °C) and the stage of long-term (9 cycles with e ~0.02 per cycle) hot deformation (at 750 °C). It has been established that in the process of long-term hot deformation, the relative value of the softening of the sample is only about 8%. The results obtained make it possible to predict the stable operation of a stamping tool made of steel with regulated austenitic transformation during exploitation at temperatures of 450–750 °C.

На основе расчетных данных выбраны составы экспериментальных алюминиевых сплавов, которые отличаются наименьшей склонностью к горячеломкости при литье. Для экспериментальных сплавов методом горячей прокатки из слитков получены листы толщиной 2,5 мм. Проведена оценка склонности экспериментальных сплавов к трещинообразованию при сварке плавлением по пробам «рыбий скелет», крестовая проба, кольцевая проба и пробе МВТУ. Показано, что свариваемость сплава Al–1Ca–5,5Zn–1,5Mg–0,5Mn (сплав 1) находится на уровне свариваемости серийного сплава 1915. Анализ полученных данных показывает, что характеристики трещинообразования сплава Al–2Ca–2,5Mg–0,4Mn (сплав 2) (коэффициент трещинообразования и критическая скорость деформирования образца) находятся на уровне, соответствующем сплаву АМг3. Исследованные сплавы при соответствующей подготовке поверхности не склонны к порообразованию при сварке плавлением. Определены механические свойства соединений исследованных сплавов при аргонодуговой и плазменной сварке.

Based on the calculated data, the compositions of experimental aluminum alloys which are characterized by the lowest tendency to hot brittleness during casting have been selected. Sheets with a thickness of 2.5 mm were obtained from ingots for experimental alloys by hot rolling. It is shown that the weldability of the Al–1Ca–5.5Zn–1.5Mg–0.5Mn alloy is at the level of weldability of serial alloy 1915. Analysis of the obtained data shows that the cracking characteristics of the Al–2Ca–2.5Mg–0.4Mn alloy (alloy 2) (cracking coefficient and critical deformation rate of the sample) are at the level corresponding to the AMg3 alloy. The studied alloys with appropriate surface preparation are not prone to pore formation during fusion welding. The mechanical properties of the compounds of the studied alloys during argon-arc and plasma welding are determined.
ERK 1/2 Pathways: Discoveries in Disease Causation and Developments in Their Treatment
Authors: Chandiok Taarah
Published: June 2024

This study delves into recent research on ERK1/2 signaling pathways, exploring their critical role in cellular processes such as proliferation, differentiation, migration, and apoptosis. Dysregulation of these pathways contributes to various human diseases, including cancers, autoimmune disorders, and neurodegenerative conditions. The study highlights the potential therapeutic benefits of targeting ERK1/2 through inhibitors, which demonstrate efficacy in treating autoimmune and inflammatory diseases, as well as cancer. However, issues like drug resistance, off-target effects, and unintended consequences of systemic MEK/ERK inhibition present challenges. Tumor progression locus 2 (TPL2) is an important regulator of immune responses that conveys inflammatory signals to downstream effectors, Targeting upstream regulators like TPL2 or employing combinatorial therapies such as inhibition of Akt may offer more precise treatment approaches. The study also explores emerging treatments, including kinase inhibitors from extremophilic microorganisms, which offer new perspectives on drug development. Ultimately, a comprehensive understanding of ERK1/2's potential targets is crucial to developing effective therapies for a range of diseases, promising significant advances in public health.

Authors: Bobrova N. A.
Published: June 2024

The subject of the article is trends in Russian legal science.

The aim of the article is to analyze and systematize the facts accumulating in legal sciences and science studies, which develop into trends that negatively affect the state of scientific jurisprudence, its categorical apparatus and practical significance, including for lawmaking and law enforcement.

Methodology. The author uses historical, sociological, formal-legal, systemic and comparative methods.

The main results. The following trends have been studied: substitution of the relevance and novelty of the topic with considerations of political conjuncture, scientific fashion and other pseudo-scientific considerations; Constitutional reforms as a new round of constitutionalization in the aspect of correlation between constitutionalization and interdisciplinarity of legal sciences; the danger of escalating the interdisciplinarity of legal research into the erosion of its subject; methodological eclecticism; weighting of scientific language, negligence and incorrect use of certain legal terms; misuse of foreign terminology; disunity of science and practice of law enforcement.

Conclusions. Since the degree of practical implementation of scientific and legal research into legislative and law enforcement practice is too low, a more effective mechanism for analyzing and implementing specific proposals from legal scientists is needed.
The role of social factors in the criminal behavior of women with mental anomalies
Authors: Kunts E. V.
Published: June 2024

The subject. The article analyzes the individual consciousness of a woman, which allows her to adapt to the surrounding social reality and to integrate into its structure.

The purpose of the article is to confirm or disprove hypothesis that pathological features are not decisive in the criminal behavior of a sane woman, including those with mental abnormalities. They act in conjunction with the social content of her consciousness.

The methods of the sciences of criminology, criminal law, penal enforcement law, sociology, psychiatry, legal psychology and jurisprudence were used.

Main results. Her consciousness is not an externally introduced element of social nature, it is intrinsic to her as a way of her existence, it is the result of her own social existence. The level of consciousness of a woman is adequate to the richness of her social activity, thus, consciousness is, first of all, individual in nature. Whereas the individual consciousness of a woman is significantly influenced by the surrounding people, the experience of previous eras and generations.

Conclusions. Consciously volitional potencies are given to a woman from birth. The study of mental processes of personality is necessary for law enforcement officials representatives of the judicial system to logically and correctly censor the testimony of a woman a criminal, because without knowledge of the general laws of the course of mental processes, it is impossible to assess the specificity of behavior, formed under certain external or internal influences. It is noted that their development depends on the woman herself, her interaction with the surrounding world, which confirms the special influence of social factors on the criminal behavior of women with mental anomalies.

Background: The scientific interest in dominant Candida species colonizing the surface of conventional and double-layer dentures (D-LCDs) is still topical. Numerous studies are comparing fungal colonization in both types of removable dentures. Aim: Performing a comparative analysis of the colonization of Candida spp. on the dentures surfaces of the conventional (CCDs) and the double-layer dentures (soft-lined) complete dentures (D-LCDs) over six months, placing them under the same intraoral in vivo conditions. Methods: For isolating Candida spp., specimens were obtained from inner denture surfaces using two sterile swabs, one for the upper complete denture (n=28) and one for the lower complete denture (n=28). The culture-based Candida detection method with CHROM agar was used to identify Candida species. Results: In the third month after dentures delivery C. Albicans is the predominant Candida spp. found on both types of complete dentures surface and isolated in 46 % of the patients with conventional complete dentures and 43 % with double-layer dentures (p>0.05). In the sixth month of the finished prosthetic treatment, combinations of C. Albicans and non-albicans Candida, predominantly C. Tropicalis, C. Glabrata and C. Parapsilosis, were found in 43 % of D-LCDs and 45 % of CCDs (p>0.05). Conclusion: There was no difference in colonization based on the different materials used for denture fabrication. However, there is a significant proportional change for all studied Candida spp. over the period (3-6 months after delivery), irrespective of the denture material used.
ОБ ОДНОЙ ЛИНЕЙНОЙ ОБРАТНОЙ ЗАДАЧЕ С ПОЛУПЕРИОДИЧЕСКИМИ КРАЕВЫМИ УСЛОВИЯМИ ДЛЯ ТРЁХМЕРНОГО УРАВНЕНИЯ ТРИКОМИ В НЕОГРАНИЧЕННОМ ПАРАЛЛЕЛЕПИПЕДЕ

В данной статье рассматриваются вопросы корректности одной линейной обратной задачи для трехмерного уравнения Трикоми в неограниченном паралилепипеде.
Для доказательства единственности обобщённого решения используется метод интегралов энергии. Для доказательства существования обобщённого решения сначала используется преобразование Фурье и в результате получается новая задача на плоскости, а для разрешимости этой задачи используется методы "ε -регуляризации" и априорных оценок. Используя эти методы, и равенство Парсеваля, докажем единственность, существование и гладкость обобщённого решения одной нелокальной краевой задачи периодического типа для трехмерного уравнения смешанного типа первого рода второго порядка.

В статье предложены следующие отношения эквивалентности в пространстве решений начальных задач для динамических систем. Отношение асимптотической эквивалентности: расстояние между двумя решениями стремится к нулю при увеличении времени, соответствующее фактор-пространство названо асимптотическим фактор-пространством; отношение асимптотической экспоненциальной эквивалентности: расстояние между двумя решениями убывает экспоненциально при увеличении времени, соответствующее фактор-пространство названо асимптотическим экспоненциальным фактор-пространством. Отношение хаусдорфовой асимптотической эквивалентности: неограниченное сближение решений с обратимым преобразованием аргумента с увеличением времени, соответствующее фактор-пространство названо хаусдорфовым асимптотическим фактор-пространством. Показано, что понятие хаусдорфова асимптотического фактор-пространства создает новые математические объекты.

Рассмотрены вопросы разрешимости нелокальной краевой задачи для одного псевдопараболического дифференциального уравнения. С помощью метода ряда Фурье получена счетная система обыкновенных интегральных уравнений Фредгольма второго рода для определения коэффициентов неизвестной функции. При доказательстве однозначной разрешимости счетной системы применен метод последовательных приближений в сочетании его с методом сжимающих отображений.  Показаны абсолютная и равномерная сходимость и возможность почленного дифференцирования полученных рядов Фурье. Результаты работы сформулированы в виде теорем.

The goal of this paper is to survey problems of axiomatization in general, to survey of axiomatization of motion in various spaces and to present a system of axioms to present controlled motion of stretched objects with bounded velocity. Survey of peculiarities of axiomatization in mathematics based on works by A.A. Borubaev and G.M. Kenenbaeva, axiomatization of kinematical spaces is presented in the paper. A new notion of generalized kinematical space is defined: given a family of connected sets of a kinematical space (passes) and a family of connected (isomorphic) sets (things); “passes” contain continuous sequences of “objects”.

РОЛЬ ЭНЕРГЕТИЧЕСКИХ НАПИТКОВ В ЖИЗНИ СТУДЕНТОВ МЕДИЦИНСКОГО ФАКУЛЬТЕТА 3-КУРСА ОШСКОГО ГОСУДАРСТВЕННОГО УНИВЕРСИТЕТА: ВРЕД ИЛИ ПОЛЬЗА

Употребление энергетических напитков становятся все более популярным среди студентов. Учиться, работать, сдавать сессии и даже отдыхать нынешней молодежи помогают не здоровый сон и полноценное питание, а как выяснилось, наоборот- различные психостимулирующие вещества. Для студентов - это хороший способ учиться по ночам, а для спортсменов поддерживать активность. Но это польза для эпизодического функционирования, а не организма, поскольку эффект от энергетиков длится от 1,5 до 4 часов. После чего организм требует новую дозу для возвращения высокого уровня концентрации витаминов и аминокислот. Поэтому вся польза имеет временный характер.
