Možnost navigace osob v komplexech neznámých budov

This paper focuses on the problems of navigation in a vast building with the possibility of detection of a subsequent movement in different parts of the object. It describes the design of documents used for 2D and 3D navigation of courier from point A (store) to point B (in a large office building). The article also describes a design of an algorithm for navigation of persons in the building and steps leading to the design of a navigation system for vast buildings. The application is developed within the project of the University Science Park and is designed for navigation at the University of Žilina.Tento príspevok sa zaoberá problematikou navigácie v rozľahlých budovách kritickej infraštruktúry s možnou detekciou jej následného pohybu v jednotlivých častiach objektov. Opisuje tvorbu podkladov pre 2D a 3D podklady slúžiace pre navigáciu kuriéra z bodu A (sklad) do bodu B (kancelária v rozľahlej budove). V článku je ďalej opísaný navrhnutý algoritmus určený na navigáciu vstupujúcej osoby a kroky ktoré viedli k návrhu systému navigácie pre rozľahlé budovy. Vytvorená aplikácia vyvíjaná v rámci projektu Univerzitný vedecký park je navrhnutá pre potreby navigácie v priestoroch Žilinskej univerzity

An ethnographic study of long-distance relationships in the age of COVID-19

Rad daje uvid u funkcioniranje veze na daljinu, posebice tijekom pandemije COVID-19 na primjeru jedne hrvatsko-mađarske veze. Kroz radove nekolicine autora i jednim polustrukturiranim intervjuom istražit će se neka od glavnih pitanja i problema vezanih uz život u vezi na daljinu. Cilj ovoga rada je istražiti je li, te kako je iznenadna pandemija utjecala na veze na daljinu. Svrha rada je prikazati specifično iskustvo kazivača i njegov život u vezi na daljinu te način na koji partneri međusobno rade na stvaranju i održavanju bliskosti u doba izvanrednog, neuobičajenog stanja – pandemije COVID-19, a čiji bi rezultati poslužili daljnjim istraživanjima ove teme.The study gives insight into the functioning of a long-distance relationship (LDR), especially during the COVID-19 pandemic on the example of a Croatian-Hungarian couple. Using the works of several authors and one semi-structured interview, some of the questions and problems related to life in LDR will be explored. The aim of this study is to research whether and how the pandemic affected LDRs. The purpose of this study is to present the experience of the interview partner and show how partners work together to create and maintain closeness in times of emergency – COVID-19

Trasovanie vozidla na otvorenom parkovisku na základe video detekcie

This article deals with topic of transport vehicles identification for dynamic and static transport based on video detection. It explains some of the technologies and approaches necessary for processing of specific image information (transport situation). The paper also describes a design of algorithm for vehicle detection on parking lot and consecutive record of trajectory into virtual environment. It shows a new approach to moving object detecti on (vehicles, people, and handlers) on an enclosed area with emphasis on secure parking. The create dapplication enables automatic identification of trajectory of specific objects moving within the parking area. The application was created in program language C++ with using an open source library OpenCV.Tento príspevok sa zaoberá problematikou identifikácie dopravných prostriedkov v dynamickej a statickej doprave na základe video- detekcie. Ozrejmuje niektoré technológie a postupy, ktoré sú pri spracovaní špecifickej (dopravné situácie) obrazovej informácie evyhnutné. V článku je ďalej opísaný navrhnutý algoritmus na detekciu vozidla s následným záznamom pohybovej trajektórie do virtuálneho prostredia. Práca prináša nový pohľad na detekciu ale hlavne záznam trajektórie pohybujúcich sa objektov (vozidiel, osôb, manipulátorov) na uzavretých plochách, pričom kladie hlavne dôraz aj na zvyšovanie konformity služieb otvorených parkovísk. Na základe takejto aplikácie je možné automatizovane identifikovať trajektóriu pohybu špecifického objektu po parkovisku. Aplikácia bola vytvorená v opensourse softvérovom prostriedku Microsoft Visual Studio s využitím knižnice OpenCV[1]

This paper focuses on identification of persons entering objects of crucial infrastructure and subsequent detection of movement in parts of objects. It explains some of the technologies and approaches to processing specific image information within existing building apparatus. The article describes the proposed algorithm for detection of persons. It brings a fresh approach to detection of moving objects (groups of persons involved) in enclosed areas focusing on securing freely accessible places in buildings. Based on the designed algorithm of identification with presupposed utilisation of 3D application, motion trajectory of persons in delimited space can be automatically identified. The application was created in opensource software tool using the OpenCV library.Tento príspevok sa zaoberá problematikou identifikácie osôb vstupujúcich do objektov kritickej infraštruktúry a následnou detekciou ich pohybu v častiach objektov.

Green's Theorem And It's Applications

U okviru ovog završnog rada bavit ćemo se Greenovim teoremom i njegovim primjenama. Da bismo došli do samog teorema, ukratko smo naveli i ponovili osnovne pojmove. Najprije smo definirali krivuljne integrale. Nakon iskaza Greenovog teorema, proveli smo njegov dokaz za neke specijalne slučajeve. Zatim smo se dotaknuli najbitnijih pojmova o plohama. Uz Greenov teorem, predstavljen je i teorem o divergenciji te Stokesov teorem kao njegov općenitiji slučaj. Na kraju, u razmatranju primjena, govorili smo o Cauchyjevom teoremu i jednadžbi kontinuiteta.In this paper, we will deal with Green’s theorem and its applications. In order to get to the theorem itself, we briefly stated and repeated the basic terms. First we have defined curve integrals. After stating Green’s theorem, we implemented his proof for some special cases. Then we touched on the most important terms about surfaces. In addition to Green’s theorem, the divergence theorem and Stokes’ theorem were also presented as his more general case. Finally, in considering applications, we referred to Cauchy’s theorem and continuity equation

STABILITY PROBLEM - BUCKLING

U završnom radu analiziran je gubitak stabilnosti ravnih štapova opterećenih uzdužnom tlačnom silom. Rad se sastoji od teorijskog dijela i zadatka. U teorijskom dijelu objašnjeno je izvijanje u elastičnom i plastičnom području te su izvedeni izrazi za kritične sile, duljinu izvijanja i kritično naprezanje. Zadatak se sastoji od trinaest različitih poprečnih presjeka istih površina i istog pridržanja na krajevima. Za svaki presjek određena je minimalna duljina štapa pri kojoj se smije primijeniti Eulerova kritična sila. Na kraju analitičkog dijela napravljena je usporedba dobivenih duljina izvijanja. Prva usporedba je odnos svih štapova prema štapu koji ima najmanju duljinu izvijanja, a druga prema štapu s najvećom duljinom izvijanja
