Fundamental Analysis of Cycloid Ball Reducer (3rd Report)

Research of ArtemiS in a Ring-Plate Cycloid Reducer

The noise and vibration of a ring-plate pincycloid gear reducer driven by two motors are measured respectively at different rotational speeds and different loads. The data are collected and analyzed using the HEAD acoustics multi-channel noise test and analysis system. The ArtemiS is a set of analysis system for improving product quality in all areas of sound and vibration. From the frequency s...

Dynamic modelling and natural characteristic analysis of cycloid ball transmission using lumped stiffness method

The vibration of robot joint reducer is the main factor that causes vibration or motion error of robot system. To improve the dynamic precision of robot system, the cycloid ball transmission used in robot joint is selected as study object in this paper. An efficient dynamic modelling method is presented-lumped stiffness method. Based on lumped stiffness method, a translational-torsional couplin...

Fundamental Cycle of a Periodic Box-Ball System

We investigate a soliton cellular automaton (Box-Ball system) with periodic boundary conditions. Since the cellular automaton is a deterministic dynamical system that takes only a finite number of states, it will exhibit periodic motion. We determine its fundamental cycle for a given initial state.

Improvement of cycloid psychosis following electroconvulsive therapy.

BACKGROUND The treatment of choice for cycloid psychosis has traditionally been electroconvulsive therapy (ECT), but there is a lack of studies on its effectiveness. AIMS The primary aim of this register study was to determine the rates of remission and response after ECT for cycloid psychosis. The secondary aim was to examine possible predictors of outcome. METHODS Data were obtained from ...
