In this study, the finite element model updating was simulated by reducing the stiffness of the members. Due to lack of access to the experimental results, the data obtained from an analytical model were used in the proposed structural damage scenarios. The updating parameters for the studied structures were defined as a reduction coefficient applied to the stiffness of the members. Parameter v...

In this paper, optimal design of arch dams is performed under frequency limitations. Colliding Bodies Optimization (CBO), a recently developed meta-heuristic optimization method, which has been successfully applied to several structural problems, is revised and utilized for finding the best feasible shape of arch dams. The formulation of CBO is derived from one-dimensional collisions between bo...

Pedestrian detection is a significant research topic in the computer vision (CV) domain for longer period. Recently, deep learning (DL) and specifically convolutional neural network (CNN) exhibit improvement tasks such as object detection, segmentation, image classification, etc. With this motivation, study develops novel Colliding Bodies Optimization with Deep Learning based Robust Detection (...

In this paper a new method for handling collisions and permanent contacts between rigid bodies is presented. Constraint-based methods for computing contact forces with friction provide a high degree of accuracy. The computation is often transformed into an optimization problem and solved with techniques like linear or quadratic programming. Impulse-based methods compute impulses to prevent coll...

Abstract Recently, several socio-/bio-inspired algorithms have been proposed for solving a variety of problems. Generally, they perform well when applied unconstrained problems; however, their performance degenerates constrained Several types penalty function approaches so far handling linear and non-linear constraints. Even though the approach is quite easy to understand, precise choice parame...

The generalized penetration depth PD of two overlapping bodies X and Y is the distance between the given colliding position of X and the closest collision-free Euclidean copy Xε to X according to a distance metric. We present geometric optimization algorithms for the computation of PD with respect to an object-oriented metric S which takes the mass distribution of the moving body X into conside...
