Abstract Roundness/angularity is a vital shape descriptor that significantly impacts the mechanical response of granular materials and closely associated with many geotechnical problems, such as liquefaction, slope stability, bearing capacity. In this study, series biaxial shearing tests are conducted on dual-size aluminum circular hexagonal rod material. A novel image analysis technique used t...

sub basin prioritization is one of the integrated watershed management and sustainable development strategies. to protect natural resources, through marking zones of potential damage in small areas for is a primary need sustainable development. degradation potential zones project for watershed protection measures is not cost-effective economically. so this is a prerequisite for sub basin priori...

This paper addresses the mechanical behavior of buried steel pipeline crossing subsidence strata. The investigation is based on numerical simulation of the nonlinear response of the pipeline-soil system through finite element method, considering large strain and displacement, inelastic material behavior of buried pipeline and the surrounding soil, as well as contact and friction on the pipeline...

A trope is a particular property: the redness of a rose, the roundness of the moon. It is generally supposed that tropes are individuated by primitive quantity: this redness, that roundness. I argue that the trope theorist is far better served by individuating tropes by spatiotemporal relation: here redness, there roundness. In short, tropes are not this-suches but here-suches. I generally favo...

The manufacture of highly drug-loaded fine globular granules eventually applied for orally disintegrating tablets has been investigated using a unique multi-functional rotor processor with acetaminophen, which was used as a model drug substance. Experimental design and statistical analysis were used to evaluate potential relationships between three key operating parameters (i.e., the binder flo...

Previous research has demonstrated that typefaces can convey meaning over-and-above the actual semantic content of whatever happens to be written. Here, we demonstrate for the first time that people match basic taste words (sweet, sour, salty, and bitter) to typefaces varying in their roundness versus angularity. In Experiment 1, the participants matched rounder typefaces with the word "sweet,"...

Electrical discharge machining (EDM) is well established machining technique mainly used to machine complex geometries on difficult-to-machine materials and high strength temperature resistant alloys. In the present research, the objective is to study the shape of the electrode and establish the application of liquid nitrogen in reducing distortion of the electrode during electrical discharge m...

INTRODUCTION This paper describes the design and some initial evaluation of a prototype instrument for measuring roundness profiles of axially symmetric micro components with diameters below 500 μm. The instrument will measure form error in micro-scale cutting tools used for micro machining, small-hole metrology probes, and other high aspect ratio micro structures. The instrument will operate o...
