Current Serbian design codes: Transferring from a deterministic to a semi- probabilistic approach [PDF]

open access: yesTehnika, 2015
The Serbian design code for reinforced concrete structures is somewhat out-of-date in its approach to structural design. In this paper, a study into the possible transition to a semi-probabilistic approach is presented.

Reliability-based design method for shear capacity of steel reinforced engineered cementitious composites (ECC) beams

open access: yesCase Studies in Construction Materials, 2023
Engineered cementitious composites (ECC) is famous for its excellent tensile deformability and crack width control ability. Steel reinforced ECC beams under shear loading exhibit brittle behaviors, which leads to a lack of structural safety.

Resistance factor calculations for LRFD of driven piles based on setup effects

open access: yesResults in Physics, 2018
Setup effects, one of a large number of uncertainties in geotechnical engineering, can strongly enhance the bearing capacity (ultimate resistance) of driven piles after initial installation, especially for ultimate shaft resistance.

Target Tracking Algorithm in Football Match Video Based on Deep Learning

open access: yesDiscrete Dynamics in Nature and Society, 2022
After the introduction of online learning mechanism, the traditional target tracking algorithm in football game video based on TLD has good tracking ability, but it will lose the target when the target is seriously obscured.
