Reinforcement learning (RL) has received some attention in recent years from researchers, because it deals with the problem of how an autonomous manufacturing system can learn to select proper actions for achieving its ...

The paper studies the problem of the dynamic stability of a high-speed shaft, subjected to bending vibrations. The case of normal machine tool shafts placed on rigid or flexible bearings is considered for different situations. ...

The work presents firstly the representation of the typical Hysteresis-loop as function between the indoor forces of the oscillator as friction and elastic forces dependant on displacement and, otherwise, as function between ...

Base isolation systems have become a significant element to enhance reliability during an earthquake. One type of base isolation system is Friction Pendulum Bearing in which the superstructure is isolated from the foundation ...

Starting with some attributes specific to a project manager’s work, the paper presents the functions which must be performed by a project leader – planning, organizing, staffing, directing, motivating, leading – and makes ...

Modern structures of bridges and viaducts require dynamic isolation systems, designed to eliminate or mitigate the destructive effects of intense traffic and seismic activity on these constructions. This paper studies ...

This paper presents how can be design a mechanism capable of self command. It is intended as a high uniformity of the way of action, so that external control is as safe and simple. Are taken into account the concrete conditions ...

The present study presents the kinematic analysis of a mechanical structure created by cam mechanism RR-CC. It was determined the position, velocity and angular acceleration of the tapped, as depending on the position ...
