Примена беспилотне летелице „Wingtra One“ при решавању геодетско-мерачких задатака на руднику угља „Костолац“
Милица Лунгић (2024)Беспилотне летелице су нашле широку примену у разним гранама индустрије и привреде данашњице, укључујући геодетско-мерачка снимања. Са усавршавањем самог начина подршке хардвера и софтвера, дошло је до могућности у напредовању развоја самих беспилотних летелица. Самим тим се отворила сфера могућности да у релевантно кратком временском периоду дође до самог снимања, обраде и израде поузданих ортофото модела, дигиталних модела надморских висина (ДЕМ), дигиталних модела површи (ДСМ), 3D модела површи.У овом раду је детаљније објашњен сам принцип рада беспилотнелетелице ,,Wingtra One,, ...БАС систем, беспилотна летелица Wingtra, план лета, израда модела, рудник угља „КостолацБАС систем, беспилотна летелица Wingtra, план лета, израда модела, рудник угља „Костолац''... ontent/Sc67be&a- d128-4b85-954b-45142f6217e0/SRP 2020-1-RS01-KA202-065370.pdf (rpeyaero: 10.06.2024.) 7.

Geotehnički uslovi rekonstrukcije Zavičajnog muzeja u Jagodini
Milan Tokanović (2024)U radu su prikazana geotehnička istraživanja za potrebe rekonstrukcije Zavičajnog muzeja Jagodina.Zavičajni muzej u ulici Kneginje Milice br.82 u Jagodini, ima ozbiljna oštećenja pojedinih delova konstrukcije koja su nastala na objektu tokom više od 80 godina eksploatacije.Kako bi se trajno rešio problem dinamičke stabilnosti i statičke održivosti konstruktivnog sistema objekta,neophodno je bilo definisanje geotehničkih uslova u zoni interakcije prirodne sredine i konstrukcije predmetnog objekta.Izvedena su terenska i laboratorijska ispitivanja na osnovu kojih su dobijene geotehničke podloge.

Chemo-probe into the mantle origin of the NW Anatolia Eocene to Miocene volcanic rocks: Implications for the role of, crustal accretion, subduction, slab roll-back and slab break-off processes in genesis of post-collisional magmatism
Post-collisional Cenozoic magmatic activity in NW Anatolia produced widespread volcanism across the region. In the Biga Peninsula, in the west, medium-K calc-alkaline to ultra-K rocks with orogenic geochemical signature were emplaced at ~43–15 Ma (Biga orogenic volcanic rocks; BOVR). Volcanic activity in the Central Sakarya region, to the east, is mainly restricted to ~53–38Ma, but also continued during the Early Miocene with small basaltic extrusives (Sakarya orogenic volcanic rocks; SOVR). This study presents a new set of geochemical data ...E. Yalçın Ersoy, Martin R. Palmer, Ş. Can Genç, Dejan Prelević, Cüneyt Akal, İbrahim Uysal.

Anisotropic grossular–andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia
This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of wide compositional variations the garnets near the end-member of andradite (Adr > 90) are generally isotropic. Fe-rich rims exhibit LREE depletion and flat HREE pattern with weak negative Eu anomaly, including higher As and W contents. On the other side, the Fe-poorer core shows flat REE pattern ...... were used to reveal zoning and possibly inclu- sions of another mineral phase within the garnet and zircon crystals.

The use of biological markers in determination of origin and type of organic matter in the Tisza river sediments
Snežana Štrbac, Gordana Gajica, Aleksandra Šajnović, Nebojša Vasić, Ksenija Stojanović, Branimir Jovančićević (2013)The objective of the study was to determine the origin and type of organic matter (OM) of the Tisza recent sediments along the distance of 153 km through the territory of Serbia. For this purpose group organic-geochemical parameters and biomarker compositions were used. All samples contain approximately same amount of OM, which was deposited under uniform, slightly reducing conditions. Based on the distribution of n-alkanes, the origin and type of OM could not be precisely estimated. However, n-alkane patterns ......

Stepen metamorfizma metaklastita rudnika
Vanja Ćuk (2024)Zadatak ovog rada je bio, potvrda saznanja da se na planini Rudnik dogodio kontaktni metamorfizam gornjokrednih sedimentnih stena i da se ispita intenzitet kontakto-metamorfnih promena. Posle kraćeg opisa geografskog položaja, pregleda ranijih istraživanja i geologije šireg područja, usmerena je pažnja na petrološka ispitivanja metaklastita i na kontaktno-metamorfne facije. Usled stvaranja različitih vulkanogenih facija odnosno usled vulkanskih erupcija, delovanjem zagrejane magme (lave) ili zagrejanih fluida, došlo je do kontaktnog metamorfizma, na granici oligocen-miocen i do stvaranja različitih metamorfnih stena, a ...Vanja Ćuk.

Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations
The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ......

Correlation Between Dynamic CBR and Compaction and Bearing Capacity of Pavement Foundation Layers
This paper presents a dynamic California Bearing Ratio (CBRd) device that can be used on a prepared pavement foundation layer to obtain a certain parameter of the tested material in the laboratory and in situ in a direct and fast way. For the selected natural material (gravel), it is shown that the laboratory CBRd can be used to estimate the compaction and bearing capacity, because it correlates well with the parameters of the standard and modifed Proctor compaction tests. ...korelacija parametara, donji slojevi saobraćajnica, laboratorijska i terenska ispitivanja, dinamički kalifornijski indeks nosivosti CBRd...

‘Blue-’ and ‘Brown-speckled’ pottery from Qalhât, the Sultanate of Oman (13–16th centuries): Comparison with traditional Omani 19–20 century productions
Representative ‘Blue speckled’ (13–16th centuries) and ‘Brown speckled’ (13–21st century) wares recovered from the excavations in Qalhât or collected around Bahlâ city (Sultanate of Oman) were characterized by XRPD, SEM-EDS, Raman/optical microspectroscopy, and thermal expansion. Minerals present in the body (quartz, augite and albite as major phases, calcite, dolomite, rutile, anatase, phosphate, hematite and magnetite as minor phases) were identified by XRPD and/or Raman spectroscopy. SEM-EDXS microanalysis was performed on the glazes in order to compare their composition, especially ...Liliana Gianni, Hélène Renel, Aleksandar Kremenović, Philippe Colomban.
