Представяне и обработка на знания за културно-историческото и природното наследство на България в интелигентен туристически пътеводител
Get PDFДокладът представя един реинженерингов подход за разширение на базата от знания на разработвания в DeLC лабораторията на ПУ "П. Хилендарски" интелигентен туристически пътеводител с информация за българските културни, исторически и природни обекти, съхранени в съществуващи нестандартизирани бази от данни. Туристическият пътеводител се разработва като мултиагентна среда, базирана на референтната архитектура на Виртуалното физическо пространство (ViPS). Базата знания във ViPS се базират на мрежа от онтологии - OntoNet. За да използваме съществуващите бази данни, е необходимо да се създаде единна БД, базирана на стандарта CCO (Cataloging Cultural Objects) за представяне на културно-исторически обекти на ЮНЕСКО.The report presents a reengineering approach to expand the knowledge base of the intelligent Tourist Guide developed in the DeLC laboratory of Plovdiv University "Paisii Hilendarski" with information about the Bulgarian cultural, historical and natural sites stored in existing non-standardized databases. The Tourist Guide is created as a multi-agent environment based on the reference architecture of the Virtual Physical Space (ViPS). The knowledge base in ViPS is based on a network of ontologies - OntoNet. In order to use the existing databases, it is necessary to create a common database based on the CCO standard (Cataloging Cultural Objects) for the presentation of cultural and historical sites of UNESCO.Авторите изказват благодарност към научен проект ФП21-ФМИ-002 „Интелигентни иновационни ИКТ в научните изследвания в областта на математиката, информатиката и педагогиката на обучението“ към Фонд Научни изследвания на ПУ „Паисий Хилендарски“, за частичното финансиране на настоящата работа
Orbital Stability of Solitary Waves to Double Dispersion Equations with Combined Power-Type Nonlinearity
Get PDFWe consider the orbital stability of solitary waves to the double dispersion equation
with combined power-type nonlinearity
The stability of solitary waves with velocity is proved by means of the Grillakis, Shatah, and Strauss abstract theory and the convexity
of the function , related to some conservation laws. We derive explicit analytical formulas for
the function and its second derivative for quadratic-cubic nonlinearity and
parameters . As a consequence, the orbital stability of solitary waves is
analyzed depending on the parameters of the problem. Well-known results are generalized in the
case of a single cubic nonlinearity
Computing Distance Distributions of Ternary Orthogonal Arrays
Get PDFOrthogonal Arrays (OA) play important roles in statistics (used in designing experiments), computer science and cryptography. The most important problems are those about their existence and classification of non-isomorphic classes of OA with given parameters. The solving of these problems requires possible Hamming distance distributions of studied orthogonal array to be determined. In this paper we propose a method for computing of distance distributions of OA with given parameters. Comparing computed possible distance distributions of the considered OA with ones of its derivative OAs we proved some nonexistence results and found some restrictions over structure of the studied OA.Grant KP-06N32/1-2019 of the Bulgarian National Science Fund; Contract 80-10-151/24.04.2020 of the Science Foundation of Sofia University; Grant KP-06-N32/2-2019 of the Bulgarian National Science Fund
Performative Framework and Case Study for Technology-Enhanced Learning Communities
Get PDFThis paper employs the overarching concept of communities to express the social contexts within which human creativity is exercised and learning happens. With the advent of digital technologies, these social contexts, the communities we engage in, change radically. The new landscape brought about by digital technologies is characterized by new qualities, new opportunities for action, new community affordances. The term onlife is adopted from the Onlife Manifesto and used to distinguish the new kind of communities brought about by the modern digital technologies, the onlife communities. Design principles are presented to foster such communities and support their members. These principles constitute a framework that emphasizes the concept of performativity, i.e. knowledge is based on human performance and actions done within certain social contexts, rather than development of conceptual representations. To demonstrate the use of the framework and the corresponding principles, the paper presents how they can be used to analyze, evaluate and reframe a concrete system addressing creativity and learning in the field of cultural heritage (history teaching and learning). One of the most significant results is the adoption of principles that facilitate students’ engagement in rich learning experiences moving from the role of end-user towards the role of expert-user with the support of so called maieuta-designers. The result of this process is the use of the studied software not only to consume ready-made content but the creation of new, student generated content, offering new learning opportunities to the students. As the evaluation shows, these new learning opportunities enable students to develop a deeper understanding of the topics studied.Bulgarian Ministry of Education and Science under the National Research Programme "Cultural heritage, national memory and development of society" and the National

Когнитивни аспекти на киберфизичните системи за педагогическа рехабилитация: към подход "НТИИМ" в приобщаващото образование
Get PDFThe paper presents the main ideas, motivating two ongoing research projects, justifying the need to move to STEAM education. The proposed novel type of cyber-physical systems - for pedagogical rehabilitation in inclusive education - is outlined. The role of puppet theatre in maximising the learning outcomes in inclusive education is substantiated. It has been also shown that integrating game, puppet theatre and social robotics is beneficiary in the classroom. Social robots have a significant potential for transition of the cognitive analysis of the behaviour of humans and robots from the physical to the social level. This is the core of the proposed in the paper approach for the STEAM education of the future.Изследването е частично финансирано от проект CybSPEED на ЕК № 777720, H2020-MSCA-RISE-2017 (2017-2022), проект “Дигитална достъпност за хора със специални потребности: методология, концептуални модели и иновативни екосистеми” на ФНИ №КП-06-Н42/4 (2020-2023) и проект: Център за компетентност "Интелигентни мехатронни, eко- и енергоспестяващи системи и технологии" № BG05M2OP001-1.002-0023, ОП “Наука и образование за интелигентен растеж” (2014-2020)
Creating а Digital Atlas for Heritage Cities and Towns Along the Danube
Get PDFThe traditional meaning of an atlas has changed recently, with the prompt rise of digitalisation. This process has also opened new perspectives to collect and present atlas data; the interconnection of the huge quantities of the different data sets, including the new types of data and introducing atlases with new topics as an innovation. The essential meaning of an atlas has been, however, preserved even in its digitalised version – to present spatially related phenomena and items thorough their mapping.
The aim of this paper is to discuss about the structure of a digital urban atlas on the example of the creation a new one – the digital atlas of heritage cities and towns along the Danube, one of the main deliverables of DANUrB+ INTERREG Project. This atlas, planned in both hardcopy and digital versions, is still in progress; hence, the main contribution of the paper is to show the expected structure of the digital DANUrB+ Atlas by comparing the project inputs with several already existing digital urban atlases as role-models.This paper is done for INTERREG EU Danube Project “DANube Urban Brand + Building Regional and Local Resilience through the Valorisation of Danube’s Cultural Heritage – DANUrB+” 2020-2022 (No. DTP3-433-2.2)
Comments on Some Inverted Cumulative Distributions: “Saturation in the Hausdorff Sense”
Get PDFIn this note we study properties of some inverted cumulative distribution functions (CDFs). More precisely, we prove estimates for the “saturation” – d about Hausdorff metric using two–parameters generalized inverted exponential c.d.f. The technique used can be successfully applied to other commonly used CDFs in practice. We consider also modified families of adaptive functions with “polynomial variable transfer” with applications to the Antenna–feeder Analysis. Numerical examples, illustrating our results using CAS MATHEMATICA are given.National Scientific Program “Information and Communication Technologies for Unified Digital Market in Science, Education and Security (ICTinSES)”, financed by the Ministry of Education and Science
