  • Automatic construction of a morphological dictionary of multi-word units

    Cvetana Krstev, Ranka Stanković, Ivan Obradović, Duško Vitas, Miloš Utvić (2010)
    The development of a comprehensive morphological dictionary of multi-word units for Serbian is a very demanding task, due to the complexity of Serbian morphology. 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. We also offer an evaluation ...

  • The Importance of Geotechnical Investigations for the Construction of Transfer Station „Prelići“ on Landfill in Cacak – Serbia

    Dragoslav Rakić, Irena Basarić, Jovana Janković, Tina Đurić (2019)
    For the purpose of the facilities construction within the transfer station „Prelici“ in Cacak, specific geotechnical investigations were carried out based on which the technological project with the facilities schedule was developed. Significant deviations in relation to the presented results were determined during earthworks, so the additional geotechnical investigation works were carried out. Since the new investigation works have determined a different cross section of the terrain, it was proposed to move the planned facilities which led to the ...

  • The impact of temporal variability of groundwater levels on groundwater vulnerability maps in karst terrains – a case example of the Perućac spring catchment area

    Vladimir Živanović, Igor Jemcov, Nebojša Atanacković (2022)
    Groundwater vulnerability maps represent an essential tool for protecting karst groundwater resources. Vulnerability assessment is usually based on spatial evaluation of various parameters that affect the vulnerability degree and regulate the protection role of the unsaturated zone. Most of these parameters, like soil and geology conditions, are constant and do not change during the year or over several years. In contrast, some parameters, such as the groundwater level, depend on the variability of recharge conditions. By considering the variability ...

  • Hydrochemical indicators of groundwater flow in the area of “Čukaru Peki” Cu-Au underground mine in eastern Serbia

    Nebojša Atanacković, Vladimir Živanović, Jana Štrbački, Veselin Dragišić, Ivana Cvejić (2022)
    The physical and chemical properties of groundwater, together with the groundwater levels regime and rock hydraulic properties, are often used to understand and conceptualize the hydrogeological system. Prediction of the influence of mining works on groundwater, and vice versa, is a challenge due to significantly altered groundwater flow patterns in the raw materials exploitation areas in relation to natural conditions. Therefore, multiple parameters are assessed and monitored before and during exploitation to properly characterize and quantify the system for ...

    Definisanje optimalne završne konture površinskog kopa od suštinskog je značaja za ostvarivanje strateških ciljeva u razvoju rudarskih projekata. Savremeni programski paketi i metode za optimizaciju granica kopa, zasnivaju se na pronalasku završne konture koja obezbeđuje maksimalan profit. U slučaju površinskih kopova uglja, kod kojih osim profita postoji i čitav niz dodatnih kriterijuma i strateških ciljeva, princip optimizacije granica prema profitu, najčešće nije u potpunosti primenjiv.

  • Determining the Impact of Cutting Elements State on the Bucket–Wheel Excavator Vibration and Energy Consumption

    Filip Miletić, Predrag Jovančić, Miloš Milovančević, Miloš Tanasijević, Stevan Đenadić (2022)
    Background There are two types of specifc sizes’ measurements. The frst is the measurement of energy consumption in a working technological process, and the second is the measurement of vibration, which is displayed over amplitudes of speed. There is an interplay between these two processes. Increasing the power consumption, the value of the vibration speed amplitudes increases. Purpose The process of the determination of machining parameters was based on minimizing the power consumption and vibration of the cutting tool, ...

  • The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje

    Boban Pavlović, Milica Pešić-Georgiadis (2019)
    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 ...

  • On the compatibility of lexical resources for NooJ

    Ranka Stanković, Miloš Utvić, Duško Vitas, Cvetana Krstev, Ivan Obradović (2012)
    Lexical resources for many languages are provided for the NooJ linguistic development environment. Meta-data descriptions of morphosyntactic and semantic properties of these languages and their resources are a mandatory part of each language module. In this paper we analyze how well the meta-data actually describe resources for a chosen subset of languages and to what extent are they compatible across languages to support multilingual processing. We show that there is place for improvement in both directions.
