This paper focuses on investigating the driving torques of industrial robot arm joints by using the topology optimization algorithm for its links. Structural optimization criteria focus on reducing the mass of links in particular and the total mass of the system in general. Preliminary results show that there is a change in driving torques in a direction favorable for the operation of the joints when total mass of robot decreases for any trajectory.

In this research, the problems were divided into three small, medium and large groups, and for each of the solving methods the evaluation criteria was calculated. The results of this comparison indicated that non-dominated optimization algorithm outperforms the exact solving method. Therefore, it was concluded that this algorithm should be used to solve the model of real data.

This paper investigates the impact of macroprudential policies on Vietnamese public listed companies’ financial leverage over the period of 2007 to 2021. In 2011, Vietnamese Central Bank introduce credit restrictions as a monetary policy instrument to contain net credit creation by the financial sector and to safeguard the financial system as a whole. In this paper, we focus on the impact of such restrictions on the optimal leverage decision of Vietnamese non-financial firms.
