Imagining circles: empirical data and a perceptual model for the arc-size illusion [PDF]
, 2016 An essential part of visual object recognition is the evaluation of the curvature of both an object's outline as well as the contours on its surface. We studied a striking illusion of visual curvature--the arc-size illusion (ASI)--to gain insight into ...

Simulation of Fault Arc Using Conventional Arc Models
Energy and Power Engineering, 2013 Conventional arc models are usually used to research the interaction between switching arc and circuit. It is important to simulate the fault arc for arc flash calculations, choice of electrical equipments and power system protection. This paper investigates several conventional arc models for calculating the fault arcing current.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment
Advanced Engineering Materials, EarlyView.This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Research of Fault Arc of Low-voltage Distribution Line Based on Mayr Model
Gong-kuang zidonghua, 2011 In view of problems of high cost and difficult operation in practice because fault arc's research need build special experimental environment to simulate series fault arc, parallel fault arc and grounding fault arc, the paper proposed a design scheme of ...

Stress buildup in the Himalaya [PDF]
, 2004 The seismic cycle on a major fault involves long periods of elastic strain and stress accumulation, driven by aseismic ductile deformation at depth, ultimately released by sudden fault slip events. Coseismic slip distributions are generally heterogeneous

Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]
, 2007 Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.

Advanced Engineering Materials, EarlyView.Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Concentration of the Stationary Distribution on General Random Directed Graphs [PDF]
, 2013 We consider a random model for directed graphs whereby an arc is placed from one vertex to another with a prescribed probability which may vary from arc to arc.
