The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... 2009). The average daily solar radiation energy for a flat surface during winter ranges between 1.1 kWh / m in Northern Serbia and 1.7 kWh / m? in Southern Serbia, and in the summer between 5.4 kWh / m? in Northern Serbia and 6.9 kWh / m? in Southern Serbia (University of Belgrade, 2004).

Uticaj površinske obrade kamena na promenu primarne poroznosti
Ana Radivojević (2024)Površinska obrada kamena je izuzetno bitna kod stena koje se koriste u izgradnji svih vrsta objekata. Površinskom obradom se direktno utiče, ne samo na estetska svojstva kamena nego i na njegove fizičko-mehaničke karakteristike. Cilj ovog završnog rada je analiza uticaja poliranja i rezanja kao tehnoloških procesa obrade na poroznost odabranih vrsta arhitektonsko-građevinskog kamena.

Analysis and visualization of geophysical well-logging data from closely spaced boreholes
Geophysical logging measurements for determining the condition of the rock mass on the dam profile and locating the predisposed directions of water circulation and loss from the reservoir were conducted in four boreholes distributed at a close distance.
