AB  - Atmosferski aerosoli u urbanim sredinama se
sastoje od čestica različitih dijametara, koje mogu imati veličinu
od par nanometara do par mikrometara. Stoga je za merenje
koncentracije aerosola često neophodno koristiti više
instrumenata, sa principijelno različitim metodama merenja. U
ovom radu su korišćene metode zasnovane na merenju električne
pokretljivosti čestica, za opseg dijametara od 10nm do 420nm, i
merenju ekvivalentnog optičkog dijametra, za opseg dijametara
od 300nm do 10um. Kao glavni rezultat, prikazani su primeri
kombinovanja spektara veličina čestica koji su dobijeni pomoću
ove dve komplementarne metode merenja. U procesu
kombinovanja spektara veličina čestica moguće je modifikovati
raspodelu dobijenu optičkim merenjima traženjem optimalne
vrednosti indeksa prelamanja čestica tako da se dobije što bolje
slaganje sa raspodelom dobijenom merenjem električne
pokretljivosti. Kao ulazni podaci su korišćeni rezultati merenja
iz kampanje mobilnog monitoringa u Novom Sadu 2022.

AB  - In this paper, an analysis of three Serbian medieval Raška churches highlights the significance of the interaction of regular geometric shapes in the composition of their underlying proportional scheme. The complex geometry recognised in the layouts and cross-sections of these monastery churches points to the potential use of a unique triangular proportioning system. This proportional system is derived from the initial geometry of Štambuk's proportional canon, which employs two circles constrained by an equilateral triangle in a specific setting. As the essence of religious medieval structures is often related to their interior, in this paper 3D empty space moulds are created by the parametric modelling of each element of the structure. This research shows how the variation of the two critical points of the church interior, the centres of the dome and of the main apse, along with the key triangles incorporated in the proportional scheme, affect the final 3D structural model.

AB  - Architectural overview of some historical building is certainly not complete without its proportional analyzes. This study is conducted by the proportion-as-ratio principles for analyzing sacred structures, hence highlighting geometry, both in the sense of geometric interplay of basic shapes (equilateral triangle and circle) and mathematical ratio expressed by formula such as 1:1, 1:2, 1:2 , 1:1.61 (the golden mean),1: 3 , 1: 5 , 1: 6 , 1: 7 , etc. Among thethree common types of proportional systems, applied in Serbian medieval architecture (square, triangular and golden section), triangular proportional system is specifically related to the so-called Raška style group. The guiding idea of the paper is to test three similar floor plan design patterns of the three exquisite medieval structures on unique proportioning system and 3D modeling of the interior space by parametric interpretation of each structural element of the whole (arch, vault, dome and apse). Parallel overview of the main churches of Studenica, Ţiča and Gradac contains 2D drawings (floor plans and vertical sections), along with proportional analyzes of their structural elements. Each of the three floor plan design patterns complies with I. Štambuk's proportional canon, additionally enriched with intriguing triangular scheme. 3D models are created as "empty space molds" of the church interior, by modeling each element of the structure in Autodesk Revit software.

AB  - Innovative technologies often join their methodologies, instruments and techniques in solving various types of sophisticated problems in the area of architectural cultural heritage. Beside precise photogrammetric and laser scanning methods, the other less expensive and less time consuming methods for 3D scene/object reconstruction exist. The choice of tools/instruments and methodologies depends on large scale of factors (time or space limitations, finances, availability of instruments and graphic software, etc.). For particular project's purposes, 3D scene reconstruction, the chimney of an old brick factory in Belgrade with its surrounding buildings, was performed and presented as 3D digital model. The combination of 3D modeling graphic software tools,
measurement data recorded by laser based geodetic instrument and image data taken by digital camera were employed for architectural scene reconstruction. Since there was no available technical documentation, first part of the project included measurements of existing
objects. The task concerning precise dimensioning and spatial positioning, especially regarding the chimney was set. The scene (chimney and surrounding objects) was recorded by photo camera Canon Powershot A710 IS from the second floor of the Institute of Physics' building, while real geodetic measurements were obtained by geodetic instrument - total station Sokkia SET3130R3 positioned at the same view-point. Based on coordinates of some characteristic points on the chimney and the building, the scene was reconstructed and modeled in real dimensions in graphic software Auto CAD. Classical Descriptive geometry method for single image restitution was employed in addition for the purposes of correct spatial positioning (mutual relationships) of two recorded objects, and comparison of obtained results as well. This reconstruction project has its educational, cultural and documenting aims. Hence employed and gathered various disciplines and knowledge gave an adequate solution of practical engineering multidisciplinary task.

measurement data recorded by laser based geodetic instrument and image data taken by digital camera were employed for architectural scene reconstruction. Since there was no available technical documentation, first part of the project included measurements of existing
objects. The task concerning precise dimensioning and spatial positioning, especially regarding the chimney was set. The scene (chimney and surrounding objects) was recorded by photo camera Canon Powershot A710 IS from the second floor of the Institute of Physics' building, while real geodetic measurements were obtained by geodetic instrument - total station Sokkia SET3130R3 positioned at the same view-point. Based on coordinates of some characteristic points on the chimney and the building, the scene was reconstructed and modeled in real dimensions in graphic software Auto CAD. Classical Descriptive geometry method for single image restitution was employed in addition for the purposes of correct spatial positioning (mutual relationships) of two recorded objects, and comparison of obtained results as well. This reconstruction project has its educational, cultural and documenting aims. Hence employed and gathered various disciplines and knowledge gave an adequate solution of practical engineering multidisciplinary task.",

AB  - Modern technologies enable high-precision collecting of field data and its processing in order to create documentation, perform various analyses or reconstruction of buildings that are an important part of cultural heritage. This paper presents procedures and methods implemented on two devastated single-nave churches at the territory of Serbia, which have been categorized as monuments of high national importance. For the purpose of revitalization of monuments devastated due to their long time exposure to various environmental influences and wars, data acquisition was performed for two religious historical buildings which date back to the period of a great founder, dynasty ruler Stefan Lazarević (14-15th century). Both of these churches represent cultural heritage of Serbia. Data related to the Church of the Presentation of the Virgin in the village of Slavkovica near Ljig was obtained through the photogrammetric method of data acquisition, while the Church of St. George in the village of Nemenikuće on Mount Kosmaj was a subject of terrestrial laser scanning (TLS). Analyses of physical properties of material samples taken in the field were done as well. The resulting 3D models of the current state of the structures in the form of point clouds were used to perform various analyses (geometrical, architectural and construction style characteristics and construction techniques), whereby modern instruments and data processing software as well as graphics software for 3D modeling were employed. Based on the models of the current state of the structures and comprehensive analyses (historical, style, geometrical and proportional) virtual 3D models of the complete structures were created as conceptual proposals for rebuilding the devastated structures. For the church in Slavkovica this material was used for delivering a final architectural-construction design. For the purpose of creating a 3D model of some cultural monument using modern methods, field data acquisition significantly differs from classical methods of measuring and delivering technical documentation (blueprints, views, sections, etc.). Current and indispensable procedures nowadays are photogrammetry (close-range and aerial) and laser scanning (terrestrial) which give a point cloud as a result. This point cloud is further on processed using appropriate software and serves as a base for creating documentation. The additional quality of the data obtained this way is the possibility of creating virtual 3D models accompanied by animations which can be used for historical, educational, scientific, cultural and informational purposes.

Depending on selected scene being investigated (object size and dynamics, time needed for data processing and estimation), and on chosen optoelectronic system design, several solutions are available. For the fieldwork, the passive remote detection seems to be the most convenient. Economically reasonable approach with selected non-sophisticated modest equipment is proposed, evaluated and discussed. A numerical experiment is performed with own-developed algorithm in which unreal cases are automatically eliminated during the output vector data evaluation. Gaussian distribution method is implemented here. The average calculated times, resulted from simulation, were shorter than simulated values increased by 3 sigma.

AB  - Husimi function originated in phase space formulation of quantum mechanics. This function appears naturally whenever simultaneous measurement of coordinate and impulse with maximal accuracy allowed by the Heisenberg uncertainty relation is performed on a given quantum state and it represents the probability distribution for simultaneous unsharp measurement of coordinate and impulse. Husimi function may analogously be defined for any pair of conjugated variables. In analysis of time varying signals these variables are time and frequency. In this paper we consider Husimi function in time-frequency space, we derive some properties of the function and give time-frequency analysis of some characteristic signals.

AB  - This paper deals with an issue of determination of the spatial coordinates within confined
area in general terms. Mobile air space control stations were set and related to the system of spatial triangulation. As a result of the air space "scanning", targets appear in adequate representation, representing identified aircrafts and other flying objects (FOs). The main objective is interpretation of collected data processing, in order to determine the reliable coordinates of an aircraft. The problem of false target identification occurs when data are analyzed from only two stations. Descriptive Geometry method, for the construction of the planes containing rays targeted
from the station towards the flying objects, in both classic-orthogonal projections and 3D model,
as well, offers the solution of a problem. Dynamic 3D model consists of two flying objects, monitored from two stations in predefined time periods. The constructive 3D solutions represent geometrical locus of false targets trajectories, for several settings of flaying objects and monitoring
stations. The analyses have shown geometrical positioning of the third station impact to the exact
FO’s coordinates determination. The geometrical solution could be the key for the development of
numerical method, which will lead to applied software solution

AB  - Commonly implemented nickel and titanium alloys are nowadays alloyed with many new elements. Obtained in this way, new Ti-alloys are of great practical significance in aircraft industry, while Ni-alloys are important in energetic and nuclear technique. Selected alloys of titanium and nickel have been treated in vacuum by various thermo-mechanical regimes. Most of the samples have been exposed to laser beams in the air, at the atmospheric pressure, while some of the samples have been treated in vacuum conditions. Laser-induced modifications of the samples microstructures have been analyzed by various methods of investigation, which include optical- and electron microscopy (SEM). The heating up of the selected Ni- and Ti-alloys to the melting point, in selected regimes of laser operation, has been simulated by contemporary numerical methods.

Thermal effects in the case of cylindrical geometry for mono as well as multi layer structures were considered. The different aspects of interaction up to the melting point of considered materials are presented. The effect of temperature dependence of the absorption coefficients on the process of laser heating was considered. The BEM formulation is based on the fundamental solution for the Laplace equation. The numerical results for spatial as well as temporal temperature distribution inside the material bulk are presented. Two cases were considered: a mono-layer and a multi layer case. In the case of a mono-layer structure DRM and DRM-MD approaches were used, and the numerical results were compared with the analytical ones. In the multi layer case only the DRM-MD approach was used.

3D modeling of material heating with the laser beam for cylindrical geometry

AB  - In this work an analytical approach for analyzing heating of material with a laser beam is presented. A thermal model of interaction for the case of cylindrical geometry of the material and asymmetric distribution of the laser beam intensity is used and an analytical procedure is developed to analyze the temporal and the spatial distribution of the temperature field inside the bulk of material. This kind of consideration is of practical interest in cases where the excitation by the laser beam is not symmetric in respect to its position or shape, e.g., multi-mode working regimes or asymmetrical distribution of the laser beam intensity. The heating effects were considered in the temperature range up to the melting point. The thermal and the optical parameters of the material were assumed to be independent of the temperature and were given constant values in the temperature range of interest. This approach makes use of the Laplace transform, in order to eliminate dependence on time. The Fourier method of variable separation was used to obtain the temperature field distribution in the Laplace transform domain. By using the pulse response and Duhamel's principle the 3D temperature field distribution in time domain is obtained. By using an appropriate set of orthogonal functions in r directions, the numerical procedure is made more effective, saving this way the CPU time. The general solutions for the temporal as well as spatial temperature field distributions are evaluated in a closed form in terms of the particular solutions of the governing partial differential equation (PDE). Because of linearity of the governing PDE, the superposition principle was used in the case of complex distributions of the laser beam intensity. The influence of different kinds of laser beam parameters to the temperature field distributions was considered.

AB  - In this paper different aspects of laser-material interaction were considered. Semi-analytical method was developed and applied to analysis of spatial and temporal distribution of temperature field inside bulk materials. In particular, cases with cylindrical geometry, finite diameter and infinite length as well as cylindrical geometry, finite diameter and finite length were considered. For solving the governing partial differential equations (PDEs) the Laplace transform and the Fourier method of variables separation were used. In this way instead of the original governing PDEs, ordinary differential equations were solved. Particular solutions of the ordinary differential equations were used for evaluating the general solution, which was expressed in terms of series of particular solutions. The unknown coefficients in the series of particular solutions were determined using the boundary and initial conditions. The laser-material interaction was represented using the thermal model. These interactions for the cases of the high power laser in pulse and continuous regime were analysed. The incident intensity of laser radiation was under critical intensity. Using these methods the temperature field distribution was obtained in the Laplace transform domain. The convolution integral and the Green function were used to determine the temperature field in time domain. General semi-analytical methods and numerical solutions of appropriate transcendent equations were considered and numerical results for Al specimens were presented. The influences of laser beam parameters to the temperature field distribution and isothermal curves inside the bulk material were evaluated.
