This paper presents the standardized precipitation evapotranspiration index (SPEI)-based approach to agricultural drought monitoring (ADM-SPEI approach) combining well-known methods, expert’ critical opinions, and local agro-climatic specificities. The proposed has been described in detail three phases. allows its application any region modification according different conditions. of ADM-SPEI resulted obtaining a modified SPEI for crops (agricultural (AD-SPEIcrop)) Vojvodina region. In first...

Abstract We propose novel metrics based on the Kolmogorov complexity for use in complex system behavior studies and time series analysis. consider origins of discuss its physical meaning. To get better insights into nature systems analysis we introduce three measures complexity: (i) spectrum, (ii) spectrum highest value (iii) overall complexity. The characteristics these have been tested using a generalized logistic equation. Finally, proposed applied to different originating from: model...

Motivated by the One Health paradigm, we found expected changes in temperature and UV radiation (UVR) to be a common trigger for enhancing risk that viruses, vectors, diseases pose human animal health. We compared data from mosquito field collections medical studies with regional climate model projections examine impact of change on spreading one malaria vector, circulation West Nile virus (WNV), incidence melanoma. analysed obtained ten selected years standardised vector sampling 219 unique...

The impact of adverse weather conditions (AWCs) on crop production is random in both time and space depends factors such as severity, previous agrometeorological conditions, plant vulnerability at a specific development stage. Any exclusion or improper treatment any these can cause models to produce significant under- overestimates yield. analysis presented this paper focuses range indices (AMI) related AWCs that might affect real yield well simulated For purpose, the addressed four...

Barley (Hordeum vulgare L.) is often grown in sites with low rainfall and high temperature during grain filling. Because spike architecture one of basic footprints barley domestication, the importance spikes adaptation to different environments or abiotic stresses can be hypothesised. In order compare types terms kernel growth yield components, we tested 15 two-row 10 six-row winter genotypes eight where terminal drought was simulated by defoliation at 7 days after heading (7 DAH). Control...

The purpose of this paper was to choose an appropriate information dissimilarity measure for hierarchical clustering daily streamflow discharge data, from twelve gauging stations on the Brazos River in Texas (USA), period 1989-2016. For that purpose, we selected and compared average-linkage algorithm based compression-based (NCD), permutation distribution (PDDM), Kolmogorov distance (KD). also with K-means complexity (KC), highest value spectrum (KCM), largest Lyapunov exponent (LLE). Using...

Abstract Vegetative propagation of superior genotypes via stem cuttings depends on their development strong vigorous root system. Fourteen characters cutting rooting were examined in multiannual tests with 12 eastern cottonwood (Populus deltoides BARTR. EX MARSH) course evaluation utilization selection tests. Variability and relationship among characters, survival rate analyzed according to contribution expected variances the total variance results principal component analysis, stepwise...

This paper uses RiskMetrics, GARCH and IGARCH models to calculate daily VaR for Belgrade Stock Exchange index BELEX15 returns based on the normal Student t innovation distribution. In case of values are obtained applying Extreme Value Theory standardized residuals. The Kupiec's LR statistics was used test accuracy risk measurement models. main conclusions are: (1) when modelling value-at-risk it is very important have a good model volatility stock returns; (2) both stationary integrated...

The aim of this paper is to find distributions that adequately describe returns the Belgrade Stock Exchange index BELEX15. sample period covers 1067 trading days from 4 October 2005 25 December 2009. obtained models were considered in estimating Value at Risk ( VaR ) various confidence levels. Evaluation model accuracy was based on Kupiec likelihood ratio test.

Eleven sugar beet genotypes were tested for their capacity to tolerate drought. Plants grown in semi-controlled conditions, the greenhouse, and watered daily. After 90 days, water deficit was imposed by cessation of watering, while control plants continued be up 80% FWC. Five days later concentration free proline leaves determined. Analysis done three replications. Statistical analysis performed using STATISTICA 9.0, Minitab 15, R2.11.1. Differences between statistically processed Duncan...

This paper examines quantitative changes in the capacity and actual volume of Serbian apple production period 1980-2016. On basis analysis, forecast comparison performed, condition development prospects were assessed. An analysis parameters observed was based on descriptive statistics, whereas ARIMA models employed for purposes. Based values obtained, increasing trends are expected period. At end period, total number productive trees will approximate to 25 million, 340,000 tones.

In this paper, we explored the impact of time demand characteristics in supply chain on role own-account fleet optimal transport sourcing mix. For that purpose, used multiple regression analysis to evaluate simulation and optimization results, historical database a real trade company. The reveals certain indicators variability uncertainty directly number vehicles fleet. Further, intercept equation for dependent variable can be expressed as function daily demands characteristics.

The present study focuses on interpretations of the temporal variations and between urban locations sulfur dioxide (SO2), nitrogen (NO2) black smoke (BS) during period 2001-2008 in Vojvodina Region Serbia (VR_S). In this we examined pollutants concentrations household heating non-heating seasons effect heating, traffic, rainfall wind speed air pollution levels SO2, NO2 BS eight locations. analyses showed that annual limit values these as recommended by Serbian regulations recommendations...

One of the most important phases in commercial maize breeding programs is assessment value newly-developed progeny by testing hybrid combinations. In this study, non-parametric stability measures were applied to analyze genotype ? environment interaction and assess phenotypic two half-sib populations, each consisting 40 genotypes, across 9 variable environments. Non-parametric tests significance determined presence qualitative for grain yield both observed populations. Results analysis...

The relationship between twelve genotypes of eastern cottonwood (Populus deltoides Bartr.) was analyzed according to sixteen early rooting traits and cutting survival. Principal component analysis (PCA) cluster were used on data that standardized by common one alternative way standardization. Alternative standardization (standardization with within-genotype standard deviation instead genotypes? means) in order emphasize the contribution genotype effect differences among total variation....

Trellis graphics (Becker, Cleveland, and Shyu, 1996) is a very effective method for visualizing multidimensional data sets. The basic idea behind trellis to display any of large variety 1-D, 2-D or 3-D statistical plot types in layout panels, where each panel displays subset the different values one more additional discrete continuous conditioning variables. that we use illustration applications are results field experiment conducted at Institute Field Vegetable Crops Novi Sad period...
