Assessing Tractors’ Active Safety in Serbia: A Driving Simulator Study
The active safety of tractors remains a major concern in rural road environments, where tractor drivers face high crash risks due to limited vehicle visibility. In Serbia, 1.4% of crashes involve tractors, mainly due to poor visibility (64.3%), lack of beacon lights, unsafe overtaking, and unmarked stopped tractors (14.3% each). These issues reduce safety, increase fuel consumption and emissions, and cause economic losses. A driving simulator study with 117 drivers examined how visibility equipment...

g‐Function‐Based Approach for Solving Nonlinear Resistor–Inductor–Diode Circuits
ABSTRACTThis brief presents a modeling approach for a nonlinear series resistor–inductor–diode (RLD) circuit powered by either a direct or alternating voltage source—a configuration commonly encountered in power electronics and energy conversion systems. Due to the diode's nonlinear current–voltage characteristic and the inductor's dynamic response, the circuit is governed by a nonlinear differential equation. Because this equation lacks a closed‐form analytical solution, a novel approximate solution...

THE GENDER GAP IN LOWER SECONDARY SCHOOL PHYSICS COMPETITIONS: CONSIDERING NUMERIC AND SYMBOLIC PROBLEMS
Noticing the inconsistency in previous studies of gender differences in learning physics, it was determined to check whether a gender gap exists in a relatively large sample of competitors (N = 12,966) from Serbia. The aim of the research presented here was to analyze the achievements of male and female lower secondary school students, competitors in physics, at all rounds of the physics national competitions in Serbia. The population of respondents consisted of 3,392 competitors in the school year...

LCA Analysis of Alternative Materials in Asphalt Mixtures
In recent decades, there has been a growing global trend in research and application of recycled pavement materials with the addition of various alternative materials. The aim of this research is to theoretically substantiate, through a comparative analysis, the advantages and disadvantages of the analyzed pavement structures from the perspective of life-cycle costs, as well as to assess the environmental impact throughout the pavement’s life cycle. The analysis was conducted using the LCA software...
