With the advancement in intelligent devices, social media, and the Internet of Things, staggering amounts of new data are being generated, and the pace is continuously accelerating. Real-time analytics (RTA) has emerged as a distinct branch of big data analytics focusing on the velocity aspect of big data, in which data is prepared, processed, and analyzed as it arrives, intending to generate insights and create business value in near real-time. The objective of this paper is to provide an overview of key concepts and architectural approaches for designing RTA solutions, including the relevant infrastructure, processing, and analytics platforms, as well as analytics techniques and tools with the most up-to-date machine learning and artificial intelligence considerations, and position these in the context of the most prominent platforms and analytics techniques. The paper develops a logical analytics stack to support the description of key functionality and relationships between relevant components in RTA solutions based on a thorough literature review and industrial practice. This provides practitioners with guidance in selecting the most appropriate solutions for their RTA problems, including the application of emerging AI technologies in this context. The paper discusses the complex event processing technology that has influenced many recent data streaming solutions in the analytics stack and highlights the integration of machine learning and artificial intelligence into RTA solutions. Some real-life application scenarios in the finance and health domains are presented, including several of the authors’ earlier contributions, to demonstrate the utilization of the techniques and technologies discussed in this paper. Future research directions and remaining challenges are discussed.

The aim of this study was to determine urban–rural and regional differences in anthropometric characteristics among adolescents aged 12–14, as well as to present the prevalence of weight status. A total of 534 adolescents aged 12–14 from primary schools across Montenegro participated in this cross-sectional study (283 boys, aged 13.52 ± 0.42, body height 169.43 ± 8.89, body weight 60.54 ± 13.47; 251 girls, aged 13.51 ± 0.40, body height 165.54 ± 6.67, body weight 55.28 ± 9.27). The sample was divided by geographic region in Montenegro into northern, central, and coastal regions, and according to settlement type into urban and rural inhabitants. Anthropometric characteristics were assessed using a battery of seven variables: arm span (AS); body height (BH); body weight (BW); waist circumference (WC); hip circumference (HC); body mass index (BMI); and waist-to-hip ratio (WHR). BMI was categorized based on the World Health Organization’s (WHO) cut-offs. The results indicate that girls from urban areas exhibited significantly greater body height and lower BMI values compared to their rural counterparts. Similarly, boys from urban areas also demonstrated lower BMI values compared to their rural peers. However, no statistically significant differences were observed in other anthropometric characteristics between these two groups of adolescents. Based on analysis of variance (ANOVA) and post-hoc analysis, it was found that girls from central areas had significantly greater body height compared to those from northern and coastal areas. Likewise, boys from northern areas showed higher body mass and BMI values compared to those from central areas. Additionally, both boys and girls from central areas had higher values compared to those from coastal areas. Nevertheless, no significant differences were detected in other anthropometric characteristics among adolescents from these regions. This study identified significant differences in anthropometric parameters among participants based on urban–rural status and within regional divisions. However, further research encompassing a larger sub-sample and a broader array of anthropometric variables is needed to draw a more comprehensive conclusion.

The aim of this research is to determine the elastic (repulsive) properties of the futsal ball depending on the air pressure in it. Futsal ball of standard dimensions was released on the fl at solid surface from the height of nine meters for four times. At the fi rst release the air in the ball was under prescribed pressure. At the second release the pressure in the pumped ball is reduced by 5%, at the third reduced by an additional 5%, at the fourth reduced by another 5%. The setting of the experiment was carried by cinema shooting of free fall of the prescribed futsal ball and a series of rebounds after the rejection of solid surfaces. One can conclude that the distance crossed and the total duration of four successive bouncing mostly dependent on inner pressure. In this study, the initial speed of a futsal ball was unchanged and only inner pressures were changed. It was determined how much the height of the rebound is reduced and the duration of the rebound, respectively, depending on the reduction of inner pressure. Overall, it can be concluded that the initial speed of the ball can be increased by increasing the inner pressure in the ball.

The aim of this research was to determine the differences among the top football players of the two Montenegrin club FC Buducnost and FC Mladost in the morphological characteristics and body composition. A sample of 47 examinees was divided into two sub-samples. The first sub-sample of the examinees consisted of 30 players of FC Buducnost of the average age 22.73±4.33, the champions of the Montenegrin Championship in the season 2016/17, while the other sub-sample consisted of 17 players of FC Mladost of the average age of 24.59±4.66, the vice champions of the Montenegrin Championship in the season 2016/17, with the same number of points gained as the champion. Football players were tested immediately after the end of the competition season 2016/17. Morphological characteristics in the body composition were evaluated by a battery of 11 variables: body height, body weight, body mass index, fat percentage, muscle mass, bone mass, waist size, triceps skin set, biceps skin set, back skin set and abdominal skin set. The standard central and dispersive parameters of all variables were calculated. The significance of the differences between the players of the top two football clubs in the morphological characteristics and variables for assessing body composition was determined by a t-test for independent samples. It was found that the football players of the two mentioned clubs have statistically significant differences by the variables that estimate the amount of fat percentage in a favor of FC Buducnost.

The greatest threat for the public health in Serbia is definitively smoking. 1,3 billion of people in the world are smokers and 4,9 million of death at the global level are direct consequences of smoking. If this smoking rhythm continues until 2020. the number of deaths caused by smoking will have been doubled. There are 4000 identified substances in the tobacco smoke, 50 of which have been proven to be carcinogenic. Nowdays, 14000 to 15000 young people in the developed countries and 68000-84000 in the underdeveloped contries begin to smoke. 700 millions of children, the half of the whole children population, are exposed to the passive smoking.The prevalence of smoking in Serbia, although reduced by 6,9% compared to 2000 is still very high and makes 33,6% of the whole population (38,1% of men and 29,9% of women).The aim of this study was to investigate the smoking habits of preschool children's parents, motivated by the fact that the children of that age are highly sensitive and susceptible to the toxic influence of tobacco smoke, but also to check the necessity for an aggressive public health programme implementation in the aimed populations.This research, as a cross-sectional stady, is carried out among preschool children's parents, children being 4 to 6 years old that attend nursery schools in Nis.The prevalence of smoking in preschool children's parents is extremely high, and makes 46% (45,1% of men and 46,9% of women). Having taken into consideration the parental role in upbringing and education of children, as well as the influence of passive smoking, the main conclusion is that the children's health is seriously endangered. Education, making new and maintaining already existing programmes and legal obligations considering smoking are significant steps for reducing smoking and promoting health.
