A. N. Kolmogorov – 120th Anniversary
No full text[Yanev Nikolay M.; Янев Николай М.]Andrey Nikolaevich Kolmogorov (1903–1987) occupies a unique place in modern mathematics and in the scientific world. By the diversity and breadth of his scientific studies he recalls the classical natural scientists of past centuries. Topics in the theory of trigonometric series, theory of measure and sets, studies in the theory of integration, approximation theory, constructive logic, topology and geometry, functional analysis, theory of superposition of functions and Hilbert’s 13th problem, cohomology theory, topics in classical mechanics, ergodic theory, theory of turbulence, dynamic systems, diffusion equations, foundation of the probability theory and Hilbert’s 6th problem, theory of stochastic processes (Markov, stationary, branching, diffusion, . . . ), limit theorems, mathematical statistics, theory of algorithms, information theory, applications in non-linear quantum mechanics, physics, mathematical geology, biology, genetics, social sciences, articles on the theory of poetry and the statistics of text and literature, papers on the history and methodology of mathematics and the teaching of mathematics in schools. In all these branches of science Kolmogorov obtained fundamentally important results which determined the state of many fields of 20th century mathematics and possible directions of their development. Kolmogorov was really the last encyclopedist in the Mathematics. Kolmogorov created a number of scientific schools, many of them headed by his pupils
Данни за храната на столичната аристокрация XIII-XIV век
Get PDFСведенията за храната и храненето на българското население са от различен характер – местни и чужди писмени извори, пътеписи, грамоти, житийна литература, изображения в миниатюри и в монументалната живопис, археологически находки и др. Храната, с оглед суровината за нейното приготовление попада в няколко групи –растителна, животинска /съответно от домашни животни и от лов/, риба и др.
Писмените сведения и данните от археологическите разкопки ясно отделят качеството и разнообразието на храната, употребявана съответно от масовото население /проучвания в столичните квартали на Царевец и Трапезица, кварталът в Западното подножие на Момина крепост и др./, от една страна, и от друга – данните от разкопките на Царския дворец и Патриаршията, от елитните затворени комплекси на Трапезица, някои от най-значимите столични манастири.
Сред данните за храната и културата на хранене на столичния елит са обширните трапезарии, луксозните блюда от сграфито съдове, костни останки от щуки, големи екземпляри див шаран, агнета, млади едри домашни животни, ловни трофеи и др.Information about the food and nutrition of the Bulgarian population is of a different nature – local and foreign written sources, travelogues, endowment documents, passionaries, images in miniature and monumental paintings, archaeological finds and others. Given the raw material for its preparation, it falls into several groups – plant, animal (from domestic animals and hunting), fish, etc.
The written records and the data from the archaeological excavations reveal a clear distinction in quality and variety of the foods consumed by the mass population in the capital districts of Tsarevets and Trapezitsa, the district at the western foot of Momina fortress, etc., and those consumed by the elite in the Royal Palace and the Patriarchate, in the elite closed complexes of Trapezitsa, and some of the most significant metropolitan monasteries.
Our data on the food practices of the metropolitan elite is based on findings and artefacts such as extensive dining rooms, luxurious plates of sgraffito dishes, bone remains of pike, large specimens of wild carp, lambs, young large domestic animals, hunting trophies, etc
Недвижими културни ценности с национално значение в област Стара Загора – представяне и популяризиране в онлайн пространството
Get PDFПредвид нарастващото значение на модерните технологии и по-големите възможности за достъп до информация, все по-актуален става въпросът за съдържателното и атрактивно представяне на обектите на културното наследство в онлайн пространството. В този смисъл цел на изследването е да се направи оценка на видимостта, съдържателното и визуалното презентиране на недвижимите културни ценности с национално значение в област Стара Загора в Интернет въз основа на наличната информация за тях в различни сайтове: на самите обекти, на по-висша организационна структура и др. Чрез анализ на откритата информация се проследяват основните типове обекти, които се представят и популяризират. Изследва се качеството на разпространяваната информация и възможностите ѝ да задоволи конкретни търсения, както и социалните групи, към които е адресирана. Изведени са основни насоки за подобряване на онлайн презентирането и популяризирането на обектите на изследване.Given the growing importance of modern technologies and the increasing opportunities for access to information, the question of the meaningful and attractive online presentation of cultural heritage sites is becoming more and more relevant. In this sense, the aim of the study is to evaluate the visibility, content and visual presentation of the immovable cultural values of national importance in Stara Zagora district based on the available information about them on various websites. Through an analysis of the discovered information, the main types of sites that are presented and promoted are identified. The quality of the disseminated information and its ability to satisfy specific demands, as well as the main social groups to which it is addressed, are researched. Basic guidelines for improving the online presentation and promotion of the research sites are derived.Това проучване е финансирано по изследователски проект на „Фонд научни изследвания“ „Разработване на модел за интегрирано дигитално представяне на културното наследство (на примера на област Стара Загора)“, договор № КП-06-М65/3 от 16.12.2022
Приложение на образователните технологии и видео алгоритмите в Медицински университет-Варна
Get PDFVideo-learning (in the form of video films), when properly integrated into the curriculum, can make learning much more engaging and successful for medical and healthcare students. The aim of the present study was to compare the efficacy of learning practical skills (Holter placement) in Nursing students. The students were divided into two groups of 8 students each. The first group was given an algorithm on paper, and the second group - a specially made video film. The results showed that the acquisition of this medical manipulation was more effective in the students having access to the video film. 87.5% of the students who watched the film did well on the post-test, compared to 50% of the second group (P less than 0.05). Students learning through a video lesson show higher satisfaction and retention of knowledge and skills. The results of the current study found that video triggers can be used effectively to capture learners' attention and deliver a visual lesson. However, threshold motivation is required for active learning to be successful.Научното изследване е проведено като част от проекта „Изследване на приложението на нови математически методи за анализ на кардиологични данни“ № КП-06-Н22/5 от 07.12.2018 г., финансиран от Фонд „Научни изследвания“ на Република България

No full text[Michailov Ivo M.; Михайлов Иво М.]In this survey we outline the milestones of several classical problems in Galois theory: Noether’s problem, the inverse problem and the embedding problem. We demonstrate the connection between these problems in the bigger context of the invariant theory of finite groups. We also point out several new results of the author and his collaborators regarding Noether’s problem and the embedding problem. 2020 Mathematics Subject Classification: 12F12, 13A50, 20D15, 14E08

В преследване на хоризонталност при разработването на платформи за интернет на нещата
No full text[Ganchev Ivan; Ганчев Иван]This paper presents an overview of the horizontal approach for the creation of Internet of Things (IoT) platforms, which allows to overcome many of the disadvantages of the vertical approach, by allowing a provider to supply only a horizontal slice in the delivery of IoT services, thus meeting better today’s expectations for efficiency and effectiveness, flexibility and scalability, openness and easy adjustment to new use cases and application scenarios, and multi-purpose use of the IoT systems built on top of such platforms. The state of the art in the area of IoT platforms development is presented along with some examples of horizontal IoT platform solutions in use today. The EMULSION IoT platform, developed by following the horizontal approach, is briefly described at the end. 2020 Mathematics Subject Classification: 68M10, 68M14, 68M18, 68T09
