The Dynamics of Byzantine–Serbian Political Relations
Get PDFThe purpose
of this paper is to present the general lines of development
of Byzantine–Serbian political relations, taking into
consideration their dynamic component, as an introduction
to the chapters that follow, which are dedicated to
a more detailed analysis of the archeological aspects of
the cultural spreading of Byzantine civilisation, also in
its variable space, a spreading that marked the long medieval
period in Serbia, with influences that survived in
the times which followed. Political relations, complex in
their syndromic and synergic nature, due, understandably,
to the limited space of the volume, have been constrained
to the exposition of the main elements concerning
relations between the states and rulers in the field of
political practice and political conceptions, as well as to
the important events from state and church history. For
the same reason, the bibliography has been reduced to the more recent historiographical production in which
older references and the knowledge of previous generations
have been incorporatedPublished on the occasion of the 23rd international congress of Byzantine studie
Teorijski I normativni okvir zaštite kritične infrastrukture u Crnoj Gori
Get PDFSvjesna činjenice da efikasan sistem zaštite kritičnih infrastruktura stvara preduslove za
normalno i nesmetano funkcionisanje šireg društvenog sistema, Crna Gora poslednjih godina ulaže
značajne napore, kako u pogledu normativnog definisanja tog sektora, tako i na planu iznalaženja
optimalnih mehanizama zaštite nacionalne kritične infrastrukture. Ove napore ne treba shvatiti
isključivo kao reagovanje na savremene trendove u ovoj oblasti, već i kao nužnost, odnosno obavezu
usklađivanja nacionalnog zakonodavstva i prakse sa pravnim tekovinama Evropske unije (Acquis
communautaire) u procesu priključivanja Crne Gore EU. Sve to predstavlja i diskontinuitet sa ranijim
stanjem u kome je nacionalna kritična infrastruktura posmatrana isključivo iz ugla oružanih snaga i
potreba sistema odbrane države. U aktuelnim okolnostima, posebno se osjetljivim smatra spektar
vitalnih sektora koje obuhvata kritična infrastruktura i čiji djelimičan ili potpun prekid rada može
narušiti normalno funkcionisanje određenog sistema i ugroziti nacionalnu bezbjednost. S druge
strane, od kritične infrastrukture Crne Gore očekuje se da pruža osnovne usluge koje podržavaju
razvoj crnogorskog društva i održavaju način na koji život u njemu funkcioniše. U vezi sa tim, kao
jedan od prvih zadataka se nameće definisanje sektora infrastrukture koji su od vitalnog značaja i kao
takvi predstavljaju kritičnu infrastrukturu.
Bezbjednost sistema kritične infrastrukture i njihovih funkcija nije značajna samo za državne
institucije, budući da se bezbjednosne dileme u pogledu zaštite kritične infrastrukture mogu pojaviti
u i privatnom sektoru koji se pojavljuje kao partner u izvršavanju misija i zadataka u toj oblasti. U
vezi sa tim, ilustrativni su primjeri pojedinih država u kojima se resursi kritične infrastrukture, s
obzirom na njihove specifičnosti i razmjere štetnih posledica potencijalnih napada i ugrožavanja, u
današnjem vremenu štitite primjenom integrisanog modela korporativne bezbjednosti, pri čemu se
neke funkcije povjeravaju specijalizovanim provajderima usluga privatnog obezbjeđenja. Ovako
zamišljeni integrisani model zaštite u objektima i sistemima kritične infrastrukture bi, nakon
izdvajanja funkcija koje obavljaju pripadnici privatnih kompanija za obezbjeđenje angažovani po
principu outsourcing-a, mogao obuhvatiti veliki broj aktivnosti i djelatnosti u cilju adekvatne zaštite
kritične infrastrukture. Predmetni model je važan za Crnu Goru, jer delegitimiše tradicionalno
shvatanje prema kojem samo država ima monopol nad poslovima bezbjednosti, dok privatne
bezbjednosne kompanije, zbog svoje profitno orijentisane prirode, nijesu pogodne za partnera javnom
bezbjednosnom sektoru. U vezi sa tim, treba imati u vidu da u pojedinim visokorazvijenim državama
privatni sektor ima potpuni partnerski odnos sa javnim sektorom, ne samo u zaštiti kritične

The Compensatory Bargaining Set of a Cooperative N-Person Game with Side Payments
Get PDFThe bargaining sets have been introduced as solution concepts for cooperative n-person games with side payments by R. J. Aumann and M. Maschler (1964). A further study on the relationships between various concepts of solution for such games is due to R. J. Aumann and J. Dreze (1975). The Aumann/Maschler definition of a bargaining set relies upon a stability principle imposed to the payoffs in this set: an admissible payoff belongs to a bargaining set if for every objection against this payoff there is a counter objection. Two modification of the stability principle have been discussed in earlier papers of the author (Dragan,1985,1987,1988)

Development of real-time flight control system for low-cost vehicle
Get PDFIn recent years, more and more light aircraft enter our daily life, from Agricultural
applications, emergency rescue, flight experiment and training to Barriers to
entry, light aircraft always have their own advantages. Thus, they have become
more and more popular.
However, in the process of GDP research about Flight Control System design
for the Flying Crane, the author read a lot of literature about Flight Control
System design, then noticed that the research in Flight Control System have
apparently neglected to Low-cost vehicles. So it is necessary to do some study
about Flight Control System for this kind of airplane. The study will more
concern the control law design for ultra-light aircraft, the author hopes that with
an ‘intelligence’ Flight Control System design, this kind of aircraft could
sometimes perform flying tasks according to a prearranged flight path and
without a pilot.
As the Piper J-3 cub is very popular and the airframe data can be obtained
more easily, it was selected as an objective aircraft for the control law design.
Finally, a ¼ scale Piper J-3 cub model is selected and the aerodynamics
coefficients are calculated by DATCOM and AVL. Based on the forces and
moments acting on the aircraft, the trim equilibrium was calculated for getting
proper dynamics coefficients for the selected flight conditions. With the aircraft
aerodynamics coefficients, the aircraft dynamics characteristics and flying
qualities are also analyzed. The model studied in this thesis cannot answer
level one flying qualities in the longitudinal axis, which is required by MIL-F-
8785C. The stability augment system is designed to improve the flying qualities
of the longitudinal axis.
The work for autopilot design in this thesis includes five parts. First, the whole
flight profile is designed to automatically control aircraft from takeoff to landing.
Second, takeoff performance and guidance law is studied. Then, landing
performance and trajectory is also investigated. After that, the control law
design is decoupled into longitudinal axis and later-directional axis. Finally,
simulation is executed to check the performance for the auto-controller
Literary Navigations. The Sea Imagery of Dragan Velikić
Get PDFThis article explores the function of the sea images in the fiction of the Serbian contemporary writer Dragan Velikić. The sea, a traditional symbol in world’s literature, is a key image in this writer’s texts, so much so that it amounts to nothing less than imagery of its own in his oeuvre. Imagery, however, that is very different from that handed down by the sea tradition. The author contends that the sea imagery, disseminated throughout Velikić’s works, allows the writer to create a network of intertextual references within his macro-text. At a deeper level, moreover, this imagery seems to have a twofold function in Velikić’s narrative: on the one hand, it mediates the writer’s complex relationship with the literary tradition of the past; on the other, it constitutes the core around which Velikić builds a number of virtual autobiographies: fictions conjuring up the past, both personal and cultural, permeated with auto-biographical overtones, Velikić’s stories evoke in their male protagonists various aspects of the author’s life, as well as of literary figures of the past, while never really giving rise to a full-fledged self-portrait. Thus, his stories, like ships navigating the sea, traverse several boundaries (between genres, historical and fictional self, past and present, life and literature), creating, through his idiosyncratic sea imagery, a fascinating narrative world
Dragan Živadinov's Zero-Gravity Theatre
Get PDFThe article was submitted on 19.12.2020.В статье предпринята попытка осветить затею создания театра невесомости словенского концептуального художника Драгана Живадинова. Для этого автор обращается к русским философским (Н. Федоров, К. Циолковский, А. Чижевский) и художественным источникам (К. Малевич), а также к провидческим исследованиям передвижения во Вселенной словенского ученого Германа Поточника Ноордунга, под влиянием которых формировалось космокинетическое творчество Д. Живадинова. Опираясь на наследие космистов и супрематистов, Д. Живадинов создает свой беспредметный антимиметический театр с пустым, освобожденным от весомости телом актера, которое в конечном итоге должен заменить технологический субститут, с экваториальной орбиты передающий в космос память об актере. Исследуются положения постгравитационного театра, основанные на трех алгоритмах с цифровой памятью об актере – биологическом (запись телесных координат), биографическом (запись профессиональной биографии) и биомехатроническом (запись генетической структуры), которые после смерти актеров будут управляться «умботом» как на сцене, так и в космосе. В центре внимания – спектакль «Биомеханика Ноордунг», осуществленный в стратосфере в самолете «Ил‑76 МДК», в котором вследствие резких перепадов давления во время полета возникало состояние невесомости как репетиция будущего освобождения тела от силы притяжения. В этих условиях актеры могли выступать в состоянии левитации, которая воспринималась как уникальный абстрактный театральный показ. Соединив учение о биомеханике Мейерхольда, задуманное в 1920‑е гг. как система упражнений актера с телом, с исследованиями Ноордунга о гравитации и способах ее преодоления, представленными рисунками вращающейся космической станции, Живадинов осуществил идею театрализации космоса. Этим спектаклем он показал, что абстрактное произведение искусства может стать по-настоящему абстрактным, лишь если оно восторжествует над силой земного притяжения, то есть потеряет свою гравитационную ориентацию и проявит себя в условиях невесомости.This paper aims to discuss the idea of creating a zero-gravity theatre, pioneered by Dragan Živadinov, a Slovenian conceptual artist. In order to do so, the author turns to Russian philosophical (N. Fyodorov, K. Tsiolkovsky, A Chizhevsky) and artistic sources (K. Malevich), as well as the space exploration envisioned by Slovenian scientist Herman Potocnik Noordung, who influenced Živadinov's cosmokinetic art. Resisting the legacy of cosmists and supremacists, Živadinov designs his objectless antimimetic theatre with a void actor, freed from weight and expected to be replaced by a technical substitute, which emits the actor’s memory from near-equatorial orbit. This article examines the foundations of post-gravity theatre, which are based on three algorithms with the digital memory of the actor: biological (recording of body coordinates), biographical (recording of professional biography), and biomechatronic (recording of genetic structure). These will be controlled by the “umbot” both on stage and in space after the death of the actors. The author focuses on the Biomechanics Noordung production, performed in the stratosphere on board an IL‑76 MDK aircraft. Due to sudden free-fall moments, the performers experienced a state of weightlessness, interpreted as a rehearsal for the future liberation of the body from gravity. In conditions which made it possible to create a dozen modes of weightlessness, the actors could perform in a state of levitation, which was perceived as a unique abstract theatrical performance. Combining Meyerhold’s theory of biomechanics, conceived in the 1920s as a system of exercises for the actor’s body, with Noordung’s research on gravity and ways to overcome it, represented by drawings of a rotating space station, Živadinov realised the idea of theatricalising the cosmos. With this performance, Živadinov shows that an abstract work of art can become truly abstract only if it triumphs over gravity, i. e. if it loses its gravitational orientation (up, down, left, right) and manifests itself in zero gravity
