AB  - Non-contact process monitoring could be a powerful tool to prevent tool misuse, detect wood species, detect tool dullness and reduce electrical energy consumption-all of which could reduce production costs. The aim of this study is to identify recognizable patterns in the sound signals produced during the circular sawing of two different wood species-beech (Fagus moesiaca) and fir (Abies alba)-and to classify them in order to obtain an intelligent machining process capable of recognizing the wood species being machined. These two wood species were selected for this study due to their morphological, physical and mechanical differences. The cutting power was also recorded during the process and measured indirectly via the motor power used. A sound signal can easily be converted into an image (spectrogram), which is suitable as a data basis for the deep learning process. Several neural networks were used to classify the sounds. In order to prepare the raw audio signal for machine learning using image recognition, it was processed in several steps. The relationship between the audio and the recorded cutting power was also investigated and found to be strongly correlated, but only for audio frequencies up to 4500 Hz. Based on the results and further analysis, the classification accuracy for wood species identification varied between 98% for MobileNetV2 and 94% for the InceptionV3 deep learning network.

AB  - Flood quantile estimation in ungauged basins is often performed using regional analysis. A regionalization procedure consists of two phases: the definition of homogeneous regions among gauged basins, i.e., clusters of stations, and information transfer to the ungauged sites. Due to its simplicity and widespread use, a combination of hierarchical clustering by Ward's algorithm and the index-flood method is applied in this research. While hierarchical clustering is very efficient, its shortcomings are the lack of flexibility in the definition of clusters/regions and the inability to transfer objects/stations from one cluster center to another. To overcome this, using silhouette width for induced clustering of stations in flood studies is proposed in this paper. A regionalization procedure is conducted on 53 gauging stations under a continental climate in the West Balkans. In the induced clustering, a negative silhouette width is used as an indicator for the relocation of station(s) to another cluster. The estimates of mean annual flood and 100-year flood quantiles assessed by the original and induced clustering are compared. A jackknife procedure is applied for mean annual flood estimation and 100-year flood quantiles. Both the Hosking-Wallis and Anderson-Darling bootstrap tests provide better results regarding the homogeneity of the defined regions for the induced clustering compared to the original one. The goodness-of-fit measures indicate improved clustering results by the proposed intervention, reflecting flood quantile estimation at the stations with significant overestimation by the original clustering.

AB  - Changes in the hydrological regime are widely investigated using a variety of approaches. In this study, we assess changes in annual and seasonal flow characteristics based on a probabilistic representation of the seasonal runoff regime at the daily time scale. The probabilistic seasonal runoff pattern is constructed by determining quantiles from marginal distributions of daily flows for each day within the year. By applying Fourier transformation on the statistics of the daily flow partial series, we obtain smooth periodical functions of distribution parameters over the year and consequently of the quantiles. The main findings are based on the comparison of the dry, average, and wet hydrologic condition zones as defined by the daily flow quantiles of selected probabilities. This analysis was conducted for ten catchments in Serbia by considering changes between two 30-year nonoverlapping periods, 1961-1990 and 1991-2020. It was found that the relative change in runoff volume is the most pronounced in the extreme dry condition zone in the winter season (-33% to 34%). The annual time shift is the largest in the dry and average condition zones, ranging from -11 to 12 days. The applied methodology is not only applicable to the detection of hydrologic change, but could also be used in operational hydrology and extreme flow studies via drought indices such as the Standardized Streamflow Index.

AB  - Distributions of the modulus of elasticity (MOE) and modulus of rupture (MOR) were characterized at three loading rates for small clear beech specimens in static bending. The correlation between MOE and MOR for all three loading rates was significant, but it weakened with increasing load rates. The analysis of the characteristics of empirical distributions, as well as the preliminary selection of the theoretical distributions for MOE and MOR, were performed on the basis of L-moments and L-moment diagrams. According to the standard for testing small specimens, MOE and MOR are determined as the arithmetic mean of the sample. Usage of the arithmetic mean is justified when the analyzed quantity is symmetrically distributed. It was found that the distribution of MOE and MOR is not always symmetric. The loading rate influences the shapes of the MOE and MOR empirical distributions, and consequently the choice of theoretical distribution. The general extreme value distribution stood out as the best one for both MOE and MOR, regardless of the loading rate, and the second overall ranked distribution is the three-parameter Weibull distribution. The loading rate affected the value of the fifth percentile in MOR, when determined from both the empirical and theoretical distributions.

AB  - Flood flow frequency analysis (FFA) plays one of the key roles in many fields of hydraulic engineering and water resources management. The reliability of FFA results depends on many factors, an obvious one being the reliability of the input data - datasets of the annual peak flow. In practice, however, engineers often encounter the problem of incomplete datasets (missing data, data gaps and/or broken records) which increases the uncertainty of FFA results. In this paper, we perform at-site focused analysis, and we use a complete dataset of annual peak flows from 1931 to 2016 at the hydrologic station Senta of the Tisa (Tisza) river as the reference dataset. From this original dataset we remove some data and thus we obtain 15 new datasets with one continuous gap of different length and/or location. Each dataset we further subject to FFA by using the USACE HEC-SSP Bulletin 17C analysis, where we apply perception thresholds for missing data representation. We vary perception threshold lower bound for all missing flows in one dataset, so that we create 56 variants of the input HEC-SSP datasets. The flood flow quantiles assessed from the datasets with missing data and different perception thresholds we evaluate by two uncertainty measures. The results indicate acceptable flood quantile estimates are obtained, even for larger return periods, by setting a lower perception threshold bound at the value of the highest peak flow in the available - incomplete dataset.

AB  - An analysis of mean annual runoff was conducted for a small ungauged catchment of the Tulovska River in the South Morava River Basin. Langbein's method, Turk's method and regional regression models were applied for obtaining the mean runoff. Long-term mean temperature, annual precipitation and the mean catchment elevation are used as input data. The estimations were conducted using various sources of climatological input data and the results were then compared. Precipitation and temperature data were derived, in a 10 km x 10 km resolution raster data format, from the digital data repository of the CarpatClim project. Point measurements of temperature and precipitation by the Republic Hydrometeorological Service of Serbia were also used as input data and compared with the raster data. The difference between the raster and point meteorological data was attributed to the effects of terrain elevation spatial variability, not captured in the raster data. The analyses showed that the predicted mean runoff can differ up to 50%, depending on the chosen method and the input data.

AB  - Koncept pragova percepcije uveden u okviru novih preporuka za ocenu velikih voda u SAD - Biltenu 17c, namenjen je predstavljanju protoka u godinama bez podataka osmatranja. U radu se na uzorku od 9 stanica sa potpunim nizom osmatranja na teritoriji Srbije, utvrđuje pogodnost korišćenja tri visine donjeg praga percepcije, na osnovu karakteristika nepotpunih nizova. Ispitano je ukupno 160 nizova. Nepotpuni nizovi su formirani na tri načina, izostavljanjem podataka od jedne do dvadeset godina u kontinuitetu, na različitim mestima u osmotrenom nizu. Rezultati upućuju na malu osetljivost na visinu primenjenih donjih pragova percepcije svih ocenjenih kvantila velikih voda na ispitivanim stanicama na Dunavu, Savi i Velikoj Moravi. Kod četiri ispitivane stanice srednje površine sliva (1000-8000 km2), kvantili velikih voda su uglavnom potcenjeni. Za stanice sa identifikovanim donjim izuzecima, bez obzira na površinu sliva, bolji rezultati su dobijeni za niži donji prag percepcije.
AB  - The concept of perception thresholds has been introduced as a part of new guidelines for flood frequency assessment in the U.S. - Bulletin 17c with intention to present missing flow data. The paper investigates the suitability of using three values as the lower perception threshold based on the characteristics of incomplete series in 9 stations in Serbia with complete datasets. A total of 160 datasets were analyzed. Incomplete datasets are formed in three ways, creating gaps from one to twenty consecutive years, at different locations in the observed dataset. The results indicate low sensitivity to the value of the applied lower perception threshold for all estimated flood quantiles at the studied stations on the river Danube, Sava and Velika Morava (area  gt  30000km2 ). In the four examined stations of the medium catchment area (~1000-8000 km2 ), the underestimated flood quantiles prevail. At stations with detected low outliers, regardless of the catchment area, better results were obtained for the smaller lower perception threshold value.

AB  - The variations in number and method of applied joints within storage furniture gave idea for this investigation. Importance of joint selection and its geometrical characteristic is clear if we bear in mind that the joints are critical points in the structure, and the rigidity and durability of storage furniture are in direct correlation with the type of the applied joint. Results presented in scientific papers provide little useful information to the engineer for the safe selection of the optimal joint. Number of joints along the connecting line (depth of the box type element) engineers determined empirically. In order to define stress state in the storage furniture, data on size of the load, that the box element has to with stand during its use, should be determined. The aim of this study was to determine the size and character of the loads in corner joints in storage furniture. Based on this data, as well as on the basis of information about the strength of the corner joints it is possible to calculate the required number of appropriate joining elements for each separate case.

AB  - Evapotranspiration is one of the most important processes within the hydrological cycle whose reliable assessment is essential in the planning and managing of land and water resources. Besides that, the water needs of plants depend directly on the size of evapotranspiration. This paper presents a comparison of reference evapotranspiration values calculated using the FAO Blaney-Criddle method, the FAO Radiation methods, the FAO Penman and the FAO 56 Penman-Monteith method with the results of measurements of evapotranspiration at the meteorological station in Košutnjak during the growing seasons of 2004, 2005 and 2006. It is shown that the application of the FAO 56 Penman-Monteith equation provides the calculated values of evapotranspiration that are closest to the results of measurement and it is recommended to apply this method for the estimation of reference evapotranspiration.

AB  - During dry periods, the flow of medium and small streams is significantly reduced and equal to groundwater flow. Since the base flows provide information about aquifer characteristics and retention characteristics of a basin, the possibilities of analysis and simulation of base flows gain importance under the conditions of intensive water use and the increasing demand for adequate water quality protection. In this paper, a model was established and used for the description of the principles governing the changes of base runoff on the basis of a streamflow hydrograph registered at the outlet of the basin on the example of the Kolubara basin up to the 'Valjevo' profile. Since the amount of base runoff from a basin cannot be measured, the results of base flows obtained using the local minimum method were adopted as the criterion for the comparison of the modeled values of base runoffs. The created model was applied for making simulations of the base runoff hydrograph during three characteristic years (rainy 1970, average 1985, and dry 1990). Deviations between the base flow values obtained using the established model and by applying the local minimum method are acceptable from the standpoint of general hydrological accuracy.

AB  - U toku suša proticaj na vodotocima je smanjen, i dominira bazni proticaj. Bazni oticaji su karakteristični za malovodne periode i pružaju informacije o raspoloživim vodnim resursima u slivu u toku suše, posebno o osobinama akvifera i retenzionim karakteristikama sliva. Ovaj rad se bavi mogućnošću analize i simulacije komponente baznog oticaja, kao i determinisanjem zakonitosti u njegovim promenama, do kojih se može doći analizom registrovanih hidrograma ukupnog oticaja u dužem vremenskom periodu. Osnova za modeliranje promena baznih oticaja u toku vremena bile su vrednosti baznih oticaja dobijene iz hidrograma ukupnih oticaja primenom grafičke metode lokalnih minimuma. Primenom formiranog modela urađene su simulacije hidrograma baznog oticaja tokom tri karakteristicne godine (kišne -1970., prosečne - 1985. i sušne - 1990) i pokazano je da su odstupanja u odnosu na vrednosti baznih proticaja dobijenih primenom metode lokalnih minimuma u granicama dozvoljenih.
AB  - During the drought the flow in streams is reduced and is dominated by base flow. Baseflows are characteristic of low flow periods and provide information on available water resources in the basin during the drought, particularly on the aquifer and retention basin characteristics. This paper deals with the possibility of analysis and simulation of baseflow, and the determination of the pattern of its changes based on the total registered streamflow hydrograph at the catchment outlet. The basis for modeling the base flow changes in the time were base flow values obtained from the streamflow hydrograph by application of the graphical local minimum method. Applying the simulation model developed in this study, simulations of base flow hydrographs were performed for three characteristic years (1970, 1985, and 1990). It was shown that discrepancies between values of the base flows obtained through application of the local minimum method and the model are within the limits of tolerance.
