Journal: Fuel processing technology / Publication Year

A new real-time 3D dynamic image analysis system was used to measure the particle shapes of different type of coal samples (lignite and hard coals) ground by different mills (ball and gyro mills). Shape factors such as circularity, ellipse aspect ratio (EAR), bounding rectangle aspect ratio (BRAR) and Feret aspect ratio (FAR) described the results.

Jul 20, 2021Flexible skew rolling (FSR) with two rollers is a new technology for forming large shaft parts, which is especially suitable for manufacturing the shafts with small-batch and multi-variety. Hollow shaft parts can achieve lightweight forming of parts under the premise of meeting strength. In this paper, an exploratory study of the hollow shaft in FSR of 40Cr steel has been conducted for

Lithium Oxide Superionic Conductors Inspired by Garnet and

The key component in lithium solid-state batteries (SSBs) is the solid electrolyte composed of lithium superionic conductors (SICs). Lithium oxide SICs offer improved electrochemical and chemical stability compared with sulfides, and their recent advancements have largely been achieved using materials in the garnet- and NASICON (sodium superionic conductor)- structured families.

Shape

May 17, 2015The jellium model is commonly used in condensed matter physics to study the properties of a two-dimensional electron gas system. Within this approximation, one assumes that electrons move in the presence of a neutralizing background consisting of uniformly spread positive charge. When properties of bulk systems (of infinite size) are studied, shape of the jellium domain is irrelevant.

Integrating Dynamics into Design and Motion Optimization

This paper presents a novel method of dynamic modeling and design optimization integrated with dynamics for parallel robot manipulators. Firstly, a computationally efficient modeling method, the discrete time transfer matrix method (DT-TMM), is proposed to establish the dynamic model of a 3-PRR planar parallel manipulator (PPM) for the first time.
