Reverse Engineering in DTs Using Object Detection
PhD. Ciprian Dragne* 1

Object detection has become a fairly widespread method in recent years for computer processing that uses artificial intelligence to detect certain sought-after objects in digital images or videos. Object detection and recognition techniques have also experienced continuous development as their implementa-tion, use, and benefits have become extremely evident through the speed with which answers are found in the images submitted to attention. Thus, applications that use object recognition have…

Implementation of Human Fall Activity Detection Systems
Dr. Taiwo Samuel Aina* 1

The elderly fall detection system has seen a rapid rise in medical devices due to the prediction of a 21.64% rise in the global population of elderly individuals over 65 by 2050. A significant challenge in researching elderly fall detection is the limited availability of data. The researcher cannot collect a large enough dataset on his own; access to care providers or medical institutions is extremely limited, and they typically reject ongoing research projects. However, such problems…

Optimal Control Design Results for Multiple Wheeled Mobile Robots
Dr. Yung-Hsiang Chen* 1 Chan-Hong Chao 2

This research presents the optimal control design results for the nonlinear trajectory tracking of multiple wheeled mobile robots (WMRs). The purpose of this design is to propose an optimal control method for the nonlinear trajectory tracking problem of multiple WMRs. The key contribution of this research is a simplified control structure that enables effective trajectory tracking for multiple WMRs. Generally, solving the nonlinear trajectory tracking problem for multiple WMRs is…
