Određivanje parametara smičuće čvrstoće tla primenom statističke metode
Božidar Rudnjanin (2024)Određivanje parametara smičuće čvrstoće tla je od ključne važnosti u geotehničkom inženjerstvu jer utiče na stabilnost i nosivost raznih građevinskih konstrukcija. Ovaj master rad obrađuje temu primene deskriptivne statistike za analizu parametara smičuće čvrstoće tla,čime se obezbeđuje osnov za donošenje odluka o planiranju i izvođenju građevinskih projekata.U prvom delu rada, prikupljaju se relevantni podaci o smičućoj čvrstoći tla iz prethodnih laboratorijskih ispitivanja za trasu buduće brze saobraćajnice Novi Sad - Ruma.Ti podaci uključuju vrednosti smičuće čvrstoće i različite faktore ...... parka.

The Dictionary of the Serbian Academy: from the Text to the Lexical Database
In this paper we discuss the project of digitization of the Dictionary of the Serbo-Croatian Standard and Vernacular Language. Scanning and character recognition were a particular challenge, since various non-standard character set encoding was used in the course of the almost 60-year long production of the dictionary. The first aim of the project was to formalize the micro-structure of the dictionary articles in order to parse the digitized text of and transform it into structured data stored in relational lexical database. This approach ...... various senses of lexical entries, while the SenseRef and SenseExample contain information about prove- nance and use. The class References contains metadata about the bibliographic information from the dictionary corpus. The set of markers is partially aligned with the TEI elements (and attributes) and ...

Geotehnički uslovi izgradnje tunela „Debelo brdo“ na autoputu E-80 Niš - Pločnik
Tunel „Debelo brdo“ nazvan je po najizraženijem relјefnom obliku na ovoj drugoj deonici autoputa E-80 Niš – Pločnik. Osnovnu geološku građu na lokaciji tunela čini Mio-Plioceni kompleks heterogenog litološkog sastava. Izgradnja tunela je predviđena delom u otvorenom iskopu dužine 240 m, a delom sa podzemnim iskopom dužine 190 m. U zoni tunela, padina je okarakterisana kao uslovno stabilna, pa bi neadekvatna zasecanja mogla da izazovu klizanja terena. Iz tih razloga, u okviru rada posebno su prikazani geotehnički uslovi izgradnje ...... pa je izdvojen kao Mio-Plioceni . laporovite gline zone raspadanja (u zoni Debelog brda preko 10 m) dok se povremeno [3,4].

Geotechnical zoning of the terrain along the first section of E-80 highway in Serbia – SEETO route 7
Part of E-80 highway that passes through Serbia (from the city of Nis to the administrative border Merdare) is 77 km long. The highway is divided into two sections: the first from Nis to Plocnik (39.4 km long) and the second from Plocnik to the administrative border with Kosovo. The route is designed through a typical plain and hilly terrain in which different geological units are dominant: crystalline schists, neogene sediments of foothills and quaternary sediments in the valley ...... landslides (Figure 5). Pliocene coarse grained complex is saturated, and larger number of active wells is registered in the zone of outlet portal of the tunnel „Bozurna“, so the permanent influence of groundwater on the tunnel is expected (it is confirmed by observations in piezometers) ...Dragoslav Rakić, Zoran Berisavljević, Irena Basarić, Snežana Bogdanović, Jovana Janković.

Primena digitalne fotogrametrije u rudniku Rudnik
Digitalna fotogrametrija, lasersko skeniranje i virtuelizacija sve više pronalaze aktivne uloge u rudarstvu, prvenstveno zbog svoje široke mogućnosti primene. Laserskim skeniranjem i fotogrametrijom snimaju se i kreiraju 3D modeli otkopa, jamskih hodnika, površinskih kopova, površinskih objekata (zgrada, spomenika, predmeta), a vrši se skeniranje celih rudnika koji se rekonstruišu u 3D digitalne modele.

Manual production of such a dictionary proved to be extremely time-consuming. In this paper we present a procedure that automatically produces dictionary lemmas for a given list of multi-word units. To accomplish this task the procedure relies on data in e-dictionaries of Serbian simple words, which are already well developed.
