This research develops teaching aids for mathematics learning materials of distance, speed, and time. The making of this teaching aid is based on the needs of innovative learning, the needs of students, the results of previous research on the problem of l... see more

The critical length of grade on two-lane rural roads is used as criterion to assess the need of ascending lanes for heavy vehicles. To estimate it, a speed profile is needed, which depends on the road’s grade and length, and on the physical, dynamic and m... see more

This paper presents a primary model to maximize rail line capacity by minimizing the train headway, defining block time as the time when a train first enters until it leaves the block. The analysis was conducted under a fixed-block system, which allows on... see more

Balancing is essential in rotating machinery, which is widely employed in many technical sectors, particularly in high-speed rotor-bearing systems. The mass balancing method of the hollow shaft manufactured of composite materials is investigated in this s... see more

 
It was conducted a calculation of the parameters of the T-shaped equivalent circuit of a large asynchronous engine with the use of precise G-shaped equivalent circuit for nominal data and some characteristic sizes of the machines. It was chosen the calcul... see more

In this paper the flexural vibrations of a multi-disk rotor is considered. The analysis is made for the rotor when it is simply-simply supported and when it is free-simply supported.This is done for the asymmetric undamped case where critical speeds and r... see more
