A Modeling approach for analysis and improvement of spindle-holder-tool assembly dynamics [PDF]
, 2006 The most important information required for chatter stability analysis is the dynamics of the involved structures, i.e. the frequency response functions (FRFs) which are usually determined experimentally.

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.

Experimental study of thin part vibration modes in machining [PDF]
, 2008 The machining of thin walls generally generates milling chatter, that damage surface roughness and manufacturing tools. Stability lobes which include natural frequencies are successful in case of tool chatter.

Fuzzy stability analysis of regenerative chatter in milling [PDF]
, 2010 During machining, unstable self-excited vibrations known as regenerative chatter can occur, causing excessive tool wear or failure, and a poor surface finish on the machined workpiece. Consequently it is desirable to predict, and hence avoid the onset of

Eggshell‐Based Biochar for Superior Adsorption of Crystal Violet Dye and Fluoride From Wastewater
Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.ABSTRACT Present study investigates the efficiency of eggshell biochar as a low‐cost and ecofriendly adsorbent for the simultaneous removal of fluoride ions and crystal violet (CV) dye from wastewater. The eggshell waste was pyrolyzed to produce biochar, which was thoroughly characterized and subsequently employed for contaminant adsorption.

Modelling and Simulation of a New Variable Stiffness Holder for Milling of Flexible Details
Polish Maritime Research, 2017 Modern industry expectations in terms of milling operations often demand the milling of the flexible details by using slender ball-end tools. This is a difficult task because of possible vibration occurrence. Due to existence of certain conditions (small

Chaotic vibrations in a regenerative cutting process
, 2001 We have analyzed vibrations generated in an orthogonal cutting process. Using a simple one degree of freedom model of the regenerative cutting we have observed the complex behaviour of the system.

Sex‐Specific Response to Predator Auditory Cues in Asian Corn Borer (Ostrinia furnacalis)
Ecology and Evolution, Volume 16, Issue 1, January 2026.Females downregulate more DEGs; males upregulate under predation risk. Males boost ecdysteroid; females reduce fecundity under bat ultrasound. Female O. furnacalis reacted more strongly to auditory cues of bats than males. ABSTRACT Predation risk has profound effects on prey from phenotype to gene expression.
