APPLICATION OF CLUSTER ANALYSIS IN THE BEHAVIOUR OF TRAFFIC PARTICIPANTS RELATING TO THE USE OF SAFETY SYSTEMS AND MOBILE PHONES

This paper presents a cluster analysis related to the behavior of traffic participants in relation to the use of safety systems and mobile phones. The data on traffic behavior were downloaded from an open data portal in Serbia. Three types of cluster analysis have been applied: hierarchical clustering, Bayesian Information Criterion (BIC) clustering and model clustering. The obtained results point to the various possibilities of using these three clustering methods in the field of traffic and suggest further research

CLASSIFICATION OF ELECTRICITY CONSUMERS USING ARTIFICIAL NEURAL NETWORKS

This paper explains the process of using neural networks, as one of numerous data mining techniques, for the classification of electricity consumers. The processed data comprised more than a million recordings of electricity consumption for 21,643 consumers over the period of four years and eight months. Using a data subset (70% of the entire dataset), the network was trained for the classification of consumers according to the type of the electric meter they possess (single-rate or dual-rate) and the zone they live in (city or village). The network input data in both cases included: consumer code, reading period from-to, current and previous meter reading for both low and high tariff, dual and single rate tariff consumption for that period and their total amount, as independent variables, whereas the network output comprised dependent variable classes (zone or type of electric meter). The results show that a network created in this way can be trained so well that it achieves high precision when evaluated using the test dataset. Using the available recordings about electricity consumption, the type of the electric meter consumers possess and the zone they live in can be predicted with the accuracy of 77% and 82%, respectively. These findings can provide the basis for further research using other data mining techniques

Secluded house by Ivo Andrić – (genetic and hermeneutics analysis) Изолированный дом Иво Андрича – (генетический и герменевтический анализ)

Тема ове докторске дисертације има за предмет да истражи недовољно проучен корпус збирке приповедака коју је писац припремио за живота, али која је услед смрти остала у рукопису. Њој је претходило текстолошко истраживање рукописне грађе поводом критичког приређивања збирке приповедака Кућа на осами на научном пројекту Задужбине Иве Андрића – Критичко издање дела Иве Андрића. Текстолошка истраживања у срж су поставила питање последње пишчеве воље које је одговорило на питање основног текста збирке приповедака Кућа на осами, јер је то историјско текстолошко издање и урађено је према правилима историјско-текстолошког критичког издања. Текстолошка подлога осветлила је пишчеву поетику и стваралачку радионицу и отворила нове могућности тумачења. Зато можемо рећи да ова тема произилази из генезе збирке приповедака. Како би се у генетичкој анализи предочила пишчева стваралачка радионица, збирка приповедака Кућа на осами посматрана је у свим оним аспектима који су проистекли из њеног генетичког обликовања, те она излази из равни текстологије и улази у раван тумачења претходно успостављених односа. Генетичка анализа једног дела први је корак који происходи из предузетих текстолошких проучавања и улази у раван херменеутичке симболичке импликације. Генетичка анализа и хеременутичка поставка изнедрили су анализу структуре збирке и приповедних узуса, њених поетичких начела, обликовање јунака и поставили питање временско-просторних односа и језичко-стилских карактеристика, да би на крају успоставили анализу њених историјских извора. Ова анализа је први пут изведена на основу текстолошких истраживања и резултата тих истраживања који су дати у историјско-текстолошком критичком издању.The topic of this PhD dissertation has for subject the research of insufficiently explored story collection that writer prepared for life, but which remained in manuscript due to his death. This topic preceded the textual research of the manuscript in the occasion of critical preparation of the story collection Secluded House on the scientific project of the Ivo Andrić Foundation – Critical Edition of the Andrić’s Work. The textual research in the center put the final author's will and established the basic text of the story collection Secluded House because it is a historical textual critical edition and was done according to the rules of historical-critical edition. This background lighted the author’s poetics and his creative workshop and at the same time opened a possibility for new interpretation opportunities. Because of that, we can say that this topic emanates from the genesis story collection. To present genetic analysis, this story collection was observed in all those aspects derived from its genetic figuration. This topic comes out from the textology level and enters into the level interpretation of previously established relationships. The genetic analysis is the first step that emerges from the contractual studies and enters to the level of hermeneutics symbolic implications. Genetic analysis and hermeneutics postulate have presented the analysis of the structure of story collection and her narrative opportunities, its poetic principles, the shaping of the heroes, and the issue of time-spatial relations and language-stylish characteristics, in the end, to establish an analysis of its historical sources. This analysis was performed for the first time according to the textual research and the results of these researches that were given in the historical-textology critical edition

Ugrožavanje bezbednosti kao posledica globalnog zagrevanja

The ecological issues, primarily the viable development, protection and preservation of living and working environment, have become unavoidable, i. e. dominant issues at the world scene. Warnings are coming from everywhere. Ecological risks are global, long-lasting with incalculable consequences and irrecoverable damage. Ecological problems know no local interests and boundaries. Accordingly, the fight against ecological problems requires common, united and synchronized action. The problem of climate changes has gathered the representatives of the international community in the search for the appropriate solution. The changes happening in the nature, particularly those that represent the consequence of the emission of gases which create the greenhouse effect, require the involvement of the countries at the international level considering that these gases spread over the entire atmosphere, as well as due to the fact that the gas emission control is very expensive and therefore the common action at the international level is far more economical.Klimatske promene imaju najviše negativnih uticaja na zdravlje ljudi. Ako trend zagrevanja ostane bez kontrole, čovečanstvo će se suočiti s većim povredama, bolestima i smrtnim slučajevima kao posledicama prirodnih katastrofa i toplotnih talasa, većom učestalošću zaraznih oboljenja koja se prenose hranom, vodom i vektorima, kao i većim brojem prevremenih smrti i bolesti kao posledicom zagađenja vazduha. Nauka je jasna: zemlja se zagreva, zagrevanje se ubrzava, a odgovornost je na čoveku i njegovim aktivnostima. Čista voda i dobri higijenski uslovi, sigurna i pravilno odabrana hrana, imunizacija, nadzor nad bolestima i pravovremeni odgovor, sigurna i efikasna kontrola prenosilaca bolesti i spremnost za katastrofe predstavljaju ključne komponente prakse javnog zdravlja koje treba jačati globalno u skladu s klimatskim promenama. Donosioci odluka na svim nivoima moraju biti svesni činjenice da odluke koje utiču na urbano planiranje, transport, snabdevanje energijom, proizvodnju hrane, korišćenje zemljišta i vodnih kapaciteta istovremeno utiču i na klimatske promene i na zdravlje. Postoje jasni dokazi da globalno zagrevanje postoji. Bez hitne, neposredne aktivnosti u vidu promene načina života i stavova, efekti na globalni klimatski sistem mogu biti nagli i nepovratni, ne štedeći nijednu zemlju, uzrokujući sve češće i sve jače toplotne talase, kišne oluje, tropske ciklone i promene nivoa mora već u ovom veku. Zdravstvena struka, svesna da klimatske promene štete zdravlju, u prvim je redovima u borbi s uticajima klimatskih promena. Da bi se zdravlje sačuvalo od uticaja klimatskih promena, neophodno je da ojačamo i reformišemo postojeće zdravstvene sisteme i da se bavimo ovim problemima kako na lokalnom, tako i na globalnom nivou

Managing environmental resources

Ako se sagleda i analizira odnos izme|u životne sredine i ljudskih delatnosti, i obratno, može se primetiti da degradacija životne sredine može imati ozbiljne implikacije na ljudsko zdravlje, siromaštvo, ekonomski razvoj pa i na nacionalnu bezbednost. Ekološka kriza koja postaje sve intenzivnija u korelaciji je sa socio-ekonomskim razvojem društva. Antropogeni uzroci promene životne sredine su brojni. Dominantan je razvoj energetike, rudarstva, saobraćaja, turizma, poqoprivrede, intenzivna urbanizacija. Socio-ekonomski razvoj vrši permanentni pritisak na ekosisteme (emisija sumpor dioksida, azotnih jediwewa, ugqen dioksida, pesticida, teških metala, korišćewe bioloških, mineralnih i vodnih resursa). Odgovor društva na ekolo{ke probleme obuhvata niz političkih, pravnih i ekolo- ških aktivnosti i mera koje su usmerene na rešavawe ovih problema i maksimalnom usklađivanju socio-ekonomskog razvoja sa zaštitom životne sredine.If we consider and analyze the relations between environment and human activities, and vice versa, it is obvious that the degradation of environment can have serious implications for human health, poverty, economic development, as well as on national security. The ever intensifying environmental crisis correlates with social and economic development of the society. Anthropogenic causes of environmental changes are numerous. The most prominent ones are development in the field of power industry, mining traffic, tourism, intensive urbanization. Social and economic development inflicts constant pressure on ecosystems (emission of sulfur dioxide, nitric compounds, pesticides, heavy metals, the use of biological, mineral and water resources). The response of the society to environmental problems comprises a number of political, legal, and environmental activities and measures aimed at resolving these problems and achieving maximum harmonization of social and economic development and environmental protection

Needs to redefine civil protection sector

Цивилна заштита је делатност чије је ефикасно функ-ционисање подједнако значајно у ванредним ситуацијама у миру, као и у рату, пре, у време и након извршења безбедносних задатака. Стога је сектор цивилне заштита категоријални појам са јас-ним приоритетима, организацијом и модалитетима функционисања у сфери безбедности. Околности у којима се одвија функ-ција цивилне заштите нужно намећу неопходност редефинисања стратегије и доктрине одбране, безбедности и заштите па самим тим и измене у систему цивилног реализовања заштите. Уовом раду разматрана су два потенцијална правца према којима се усмерава систем цивилне заштите. Та два правца су: Дирекција за цивилну заштиту и Агенција за цивилну заштиту (одбрану).Civil protection represents an integrated system and the widest form of organisation, preparation and participation of citizen in humanitarian activities and rescuing tasks, in cases of elementary disasters, technical-technological accidents and other accidents and threats in war and in peace. Civil protection is dynamic category with distinctive priorities, organization and functioning modalities in protection of public interest - human lives, material goods and natural environment. As a humanitarian, social, integrative, and, above all, eminent state function, it is inalienable and indefeasible from the executive authorities of the Republic of Serbia. Functionally, civil protection system is directed towards setting up the Directorate for Civil Protection, as well as Agency for Civil Protection (Defence). Suggested models act organizationally and normatively as possible, instructively and functionally. All organizational changes in civil protection system should be directed towards the increase of citizens' protection level and decrease of losses and damages in emergency situations in war and in peace

AdS-inspired noncommutative gravity on the Moyal plane

We consider noncommutative gravity on a space with canonical noncommutativity that is based on the commutative MacDowell-Mansouri action. Gravity is treated as gauge theory of the noncommutative $SO(1,3)_\star$ group and the Seiberg-Witten (SW) map is used to express noncommutative fields in terms of the corresponding commutative fields. In the commutative limit the noncommutative action reduces to the Einstein-Hilbert action plus the cosmological term and the topological Gauss-Bonnet term. After the SW expansion in the noncommutative parameter the first order correction to the action, as expected, vanishes. We calculate the second order correction and write it in a manifestly gauge covariant way.Comment: 22 pages, no figures, final versio

Oblici i izvori ugrožavanja ekološke bezbednosti

Degradation of both living and working environment is in the focus of interest of not only the professionals and scientists but also of an ordinary man, because the man witnesses the ecological balance disturbance. The safety of individuals, global and partial social groups is conditioned by the relationship between the threats and challenges and the capability to respond to them. The safety under the contemporary circumstances and conditions implies that vitally important interests of individuals, societies and states are protected from both internal and external threats which may be economic, social, military, technological, ecological, informational and other. In addition to local conflicts, organized crime and terrorism, ecological problems, climatic changes, and infectious diseases also represent serious risks to safety today. They influence the health of population, economic stability, demographic movements, as well as population migrations.Degradacija životne i radne sredine predstavlja fokus interesovanja ne samo struke i nauke već i običnog čoveka, jer je upravo čovek svedok narušavanje ekološke ravnoteže. Bezbednost pojedinca, globalnih društvenih i parcijalnih društvenih grupa, uslovljena je odnosom između pretnji i izazova i pitanja sposobnosti da se na iste odgovori. Bezbednost u današnjim okolnostima i uslovima podrazumeva da su zaštićeni životno važni interesi ličnosti, društva i države, od unutrašnjih i spoljašnjih pretnji ekonomskog, socijalnog, vojnog, tehnološkog, ekološkog, informativnog karaktera i dr. Pored lokalnih sukoba, organizovanog kriminala i terorizma, ozbiljan rizik za bezbednost danas predstavljaju i ekološki problemi, klimatske promene, zarazne bolesti itd. Oni utiču nazdravlje stanovništva, ekonomsku stabilnost, demografska kretanja kao i migracije stanovništva

Koncept održivog razvoja u funkciji suzbijanja ekološkog kriminaliteta

Environmental safety, sustainable development and environmental protection issues are unavoidable factor of stability and balanced development of a country. In the last few decades, it became obvious that our global surroundings was seriously threatened by consequences of human activities, that led to the overall pollution, including the natural and social environment. Sustainable development and non doing harm to the environment and health of the population are the priority and the milieu suitable for the success of the future generations.Ekološka bezbednost, održivi razvoj i pitanja zaštite životne sredine, jesu nezaobilazni faktor stabilnosti i uravnoteženog razvoja jedne države. Tokom poslednjih decenija, postalo je jasno da je naše globalno okruženje pod ozbiljnom pretnjom posledica ljudskih aktivnosti koje vode ka sveobuhvatnom zagađenju, obuhvatajući prirodnu i društvenu sredinu. Održivi razvoj, odsustvo nanošenja štete prirodnoj sredini i zdravlju stanovništva jeste prioritet i milje pogodno za uspeh budućih generacija
