Micro void coalescence of ductile fracture in mild steel during tensile straining

Fracture and Structural Integrity, 2011
The ductile fracture occurs mainly in three stages i.e. void nucleation, void growth and the voidcoalescence. The present work focuses on the study the coalescence of existing micro void in a ductile material,mild steel. The specimen with holes in square

Direct measurement of the hole-nuclear spin interaction in single quantum dots

, 2010
We use photoluminescence spectroscopy of ''bright'' and ''dark'' exciton states in single InP/GaInP quantum dots to measure hyperfine interaction of the valence band hole with nuclear spins polarized along the sample growth axis.

Quantum Gravity Effects in Black Holes at the LHC [PDF]

, 2006
We study possible back-reaction and quantum gravity effects in the evaporation of black holes which could be produced at the LHC through a modification of the Hawking emission.

Experimental research on film cooling characteristics of multi-film-hole-rows

Case Studies in Thermal Engineering, 2021
The present study experimentally explores the effect of the film-hole-row layout and hole angle on the film cooling characteristics of the multi-rows of micro-film-hole by the transient infrared technique.

Evaporation of Microscopic Black Holes in String Theory and the Bound on Species [PDF]

, 2009
We address the question how string compactifications with D-branes are consistent with the black hole bound, which arises in any theory with number of particle species to which the black holes can evaporate.

Micro Hole Processing Using Electro-Chemical Discharge Machining

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Recently, micro holes processing on glass were focused on chemical and biological filed. Authors focused on Electro-Chemical Discharge Machining (ECDM) to machine micro holes on glass, and developed the ECDM device.

A Comparative Numerical Study on GEM, MHSP and MSGC

, 2012
In this work, we have tried to develop a detailed understanding of the physical processes occurring in those variants of Micro Pattern Gas Detectors (MPGDs) that share micro hole and micro strip geometry, like GEM, MHSP and MSGC etc.

Black Hole Entropy: a spacetime foam approach [PDF]

, 1997
The spacetime foam structure is reviewed briefly (topogical fluctuations and virtual black hole possibility; equation of state of the foam). A model of space foam at the surface of the event horizon is introduced.

Machining of circular micro holes by electrochemical micro-machining process [PDF]

Advances in Manufacturing, 2013
Machining of micro holes with micro electro- chemical machining (micro ECM) process has been carried out with an indigenously developed set up. This paper describes relevant problems and solutions for the circular micro holes machining process on 304 stainless steel sheets with 60 lm thickness using high speed steel cylindrical tool of diameter 500 lm ...
