Due to low stiffness of braces after yielding, the structures with buckling-restrained braces (BRBs) experience high residual drifts during an earthquake, which can be intensified by aftershocks and causes considerable damages to structures. Also, due to poor distribution of stiffness, this problem is exacerbated for irregular structures. Recently, the yielding brace system (YBS) has been intro...

In practical engineering, it is difficult to establish complex nonlinear dynamic equations based on theories of mechanics. Data-driven models are built using neural networks in this paper meet the needs high dimension, multi-scale and precision. We construct a two-coefficient loss function for whole data-driven modeling substructure according linear multi-step method. The forward Euler method c...

Simulation can be an effective training method if the simulation environment is as realistic as possible. An ‘important part of the training for Navy pilots involves flying against computer-controlled agents in simulated tactical scenarios. In order for such a situation to be realistic, the computer-controlled agents must be indistinguishable from human-piloted agents within the simulated envir...

Currently, there are a large number of traffic simulation frameworks available. Usually, the principle of these simulation frameworks is to move vehicles from some location A to some location B as the result of different equations of motion or fluid dynamics. As it is, reality is much more complex because what actually happens between A and B is highly determined by the preferences and attitude...

This paper presents novel details on the dynamic behavior of human eyes (see Fig. 1). A high speed camera is used to capture the movement of the eye surface, which is excited by an air jet. For a group of subjects the dynamic response ends shortly after the excitation is over. For another group of subjects this first phase ends with a distinct offset in the displacement, which takes a significa...

The study of the dynamic behavior of a rigid body with one fixed point (gyroscope) has a long history. A number of famous mathematicians and mechanical engineers have devoted enormous time and effort to clarify the role of dynamic effects on its movement (behavior) – stable, periodic, quasi-periodic or chaotic. The main objectives of this review are: 1) to outline the characteristic features of...
