Chatter Vibration Monitoring in the Surface Grinding Process through Digital Signal Processing of Acceleration Signal

Proceedings, 2017
The grinding process is a manufacturing process that is performed at the end of the machining chain. In such step, the workpiece has a high added-value and therefore critical problems are not allowed, as they may lead to scrap and significant financial ...

Politics and Justice: Aristotle, Rawls, and the Case for Realism in Political Theory

Philosophy &Public Affairs, EarlyView.
ABSTRACT Aristotle's analysis of stasis in Book V of the Politics offers a striking example of “distinctively political thought,” as advocated by Bernard Williams's political realism, and in contrast to the moralist approach exemplified by John Rawls. Aristotle identifies disputes over justice, driven by partial and conflicting conceptions of equality,

A vibration control method for chatter mitigation in milling process based on sliding mode control and reinforcement learning

Scientific Reports
Chatter is a self-excited vibration phenomenon that limits the productivity, surface quality and tool life of milling operations. In this study, an active chatter mitigation strategy is proposed by integrating sliding mode control (SMC) with ...

Active Control of Chatter in Milling Process Using Intelligent PD/PID Control

IEEE Access, 2018
Chatter is an obstacle for achieving high-quality machining process and high production rate in industries. Chatter is an unstable self-exciting phenomenon that leads to tool wear, poor surface finish, and downgrade the milling operations. A novel active

Effects of Lycium barbarum Residue Substituting Dietary Maize on Fecal Microbiota and Growth Performance of Crossbred Simmental Cattle

Animal Research and One Health, Volume 4, Issue 3, Page 335-346, August 2026.
The bioactive substances we extracted from Lycium barbarum residue (LBR) have a typical polysaccharide structure. When 1.80% LBR was used to replace maize in the diet, the average daily gain of rossbred Simmental was significantly increased, and anti‐inflammatory ability was improved. In addition, LBR improved the fecal microbial composition, increased

The Chatter Vibration of Lathe Tool

Transactions of the Japan Society of Mechanical Engineers, 1960
The primary chatter and regenerative chatter of the turning tools are treated in this paper. I have obtained the stability condition of the reduced equation of motion of the turning tools. The regenerative chatter may be said to consist of the forced and the self-excited vibrations.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Effect of Cross Transfer Function on Chatter Stability in Plunge Cutting

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2010
An accurate analytical model for regenerative chatter vibration in plunge cutting is proposed. Effects of the cross transfer function and the cutting force ratio on chatter stability are considered in the proposed model.
