Analysis of existing approaches to setting the intelligent management systems of transport undertakings
No full textThe problem of designing intelligent management systems (IMS) of dynamically variable objects (DO), operating under significant a priori uncertainty is considered. The analysis of existing approaches to developing DO IMS, methods, models and algorithms of their construction based on the integration of classical methods of management theory and artificial intelligence methods was presented. As examples of DO, rolling stock (TU) of the multi-mode enterprises is examined. The range of unresolved problems is identified, the purpose and objectives for the solution are formulated. Currently, the problem of designing the automatic management systems of dynamically variable objects is characterized by the transition from the paradigm of adaptive management to the paradigm of intelligent management. This is caused by a continuous complication of management objects and conditions of their operation, the emergence of new classes of computing means (in particular, distributed computing systems), high-performance telecommunications channels, and a sharp increase in the reliability and efficiency requirements for management processes under significant a priori and a posteriori uncertainty. Accounting of these factors is possible only on the basis of transition from "hard" algorithms of parametric and structural adaptation to the anthropomorphic principle of management formation
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Characterization of the structural response of a lithiated SiO<sub>2</sub> / Si interface: A reactive molecular dynamics study
No full textWe report the results of a computational study regarding the mechanical properties of a lithiated Si/SiO2 interface using reactive molecular dynamics. The study is motivated by an intended application of SiO2-coated Sinanotubes as fibers in structural batteries with a fiber-reinforced composite architecture while serving as anodes. According to the results, main failure properties due to partly irreversible bond breakage during mechanical deformation are identified, indicating agreement with bond energy/bond order based estimates. Microscopic failure properties are also identified and interpreted in view of the observed processes of bonding degradation. In particular, the effect of Li distribution on the shear deformation response is evaluated as significant.Applied Mechanic

Oleksa Kovalenko and Maksym Rylskyi: A Discourse of Relationships
No full textМета статті. На основі епістолярної спадщини висвітлити взаємини відомого в Наддніпрянській Україні літератора, перекладача, культурно-громадського діяча, лікаря за фахом О. Коваленка з видатним українським поетом, публіцистом, мовознавцем, літературознавцем, директором Інституту мистецтвознавства, фольклору та етнографії АН УРСР М. Рильським в історичному контексті 1940–1960‑х років. Методи. У статті застосовано історико-біографічний, проблемно-хронологічний, пропосографічний методи. Основні результати. Здійснено аналіз історіографії з окресленого питання, а також ми дійшли висновку, що воно й дотепер залишається не висвітленим у науковій літературі. Джерельна база дослідження ґрунтована на основі епістолярної спадщини, що зберігається в Інституті літератури НАН України. Переважну його частину було опубліковано в монографії «Зачарований Словом» Н. Буланової. Встановлено, що, починаючи з 1944 року, впродовж багатьох років існували постійні контакти між О. Коваленком і М. Рильським, в основі яких – обопільний інтерес до перекладання «Слова о полку Ігоревім». Практичне значення статті полягає в можливості використання результатів дослідження при розробці спецкурсів та у краєзнавчих навчальних проєктах. Наукова новизна полягає в постановці й розробленні актуальної для інтелектуальної біографістики проблеми взаємин творчих особистостей у контексті історичної епохи, яку в історичній науці на теперішній час усебічно й об’єктивно не розкрито. Під час дослідження розширено джерельну базу за рахунок залучення до наукового обігу епістолярної спадщини О. Коваленка і М. Рильського.The purpose of the article. Epistolary heritage is used as the base of the article. The mutual relations between a famous in the Dnieper Ukraine literary man, translator, cultural worker and public figure, doctor by profession O. Kovalenko and the prominent Ukrainian poet, publicist, linguist, literary critic, director of the AS of the Ukrainian SSR Institute of Art Studies, Folklore and Ethnography in the historical context of the 1940s – 1960s are described in the article. Methods. Historical-biographical, problematic, and chronological, proposographic methods are used in the article. The main results. The analysis of historiography on the considered issue is carried out. We have concluded that until now, the problem remains unexplored in the scientific literature. The research source of the investigation is based on the epistolary heritage, kept at the NAS of Ukraine Institute of Literature. Most of it has been published in N. Bulanova's monograph Fascinated with the Word. It has been ascertained that, starting from 1944, for many years, there have been constant contacts between O. Kovalenko and M. Rylskyi, based on a mutual interest in the translation of The Tale of Ihor’s Campaign. The practical value of the article lies in the possibility of using the results of the research in the development of special courses and also in the local history educational projects. The scientific novelty is in raising and working out the problem relevant to intellectual biography studies. It is the relationships of creative personalities in the context of a historical epoch which has not been described comprehensively and objectively in historical science yet. During research, the source base is expanded owing to the introduction of an epistolary heritage of O. Kovalenko and M. Rylskyi to the scientific circulation
