Visual needle tip tracking in 2D US guided robotic interventions
(Elsevier, 2019-02)
Percutaneous needle procedures are among the most frequently performed minimally invasive surgical procedure. For tracking the needle tip in the tissue, 2D ultrasound (US) imaging is commonly used; however, the low resolution ...
High temperature flow response modeling of ultra-fine grained titanium
(MDPI AG, 2015)
This work presents the mechanical behavior modeling of commercial purity titanium subjected to severe plastic deformation (SPD) during post-SPD compression, at temperatures of 600-900 °C and at strain rates of 0.001-0.1 ...
A retrospective view on‘‘3-dimensional radiation in absorbing, emitting and scattering media using discrete-ordinates approximation’’by J.S.Truelove
(Elsevier, 2010-06)
Discrete-ordinates (DO) approximations to the radiative transfer equation in three- dimensional enclosures have extensively been used during the last three decades. The 1988 paper by Truelove [1] is one of the pioneering ...
Design of a parallel robot for needle-based interventions on small animals
(IEEE, 2013-02)
In this paper, a novel 5-degrees-of-freedom robot for performing needle-based interventions on small animal subjects is presented. The robot can realize dexterous alignment of the needle using two parallel mechanisms, and ...
Plasmonic responses of metallic/dielectric core-shell nanoparticles on a dielectric substrate
(IOP Publishing, 2019-06)
The effect of material selection on the plasmonic response and local absorption are evaluated for core- shell nanoparticles placed over a BK7 glass substrate. Eight different core-shell pairs are studied using the vectorized ...
Effect of severe plastic deformation on the damping behavior of titanium
(Elsevier, 2019-06-01)
In this work, influence of severe plastic deformation on the damping properties of commercial purity titanium is explored. Deformation induced grain refinement improved the strength at room temperature while this effect ...
The penetration of acoustic cavitation bubbles into micrometer-scale cavities
(Elsevier, 2016)
The penetration of acoustically induced cavitation bubbles in micrometer-scale cavities is investigated experimentally by means of high-speed photography and acoustic measurements. Micrometer-scale cavities of different ...
High-speed visualization of acoustically excited cavitation bubbles in a cluster near a rigid boundary
(Springer Berlin Heidelberg, 2017)
In the present work, high-speed visualizations at one million frames/s have been used to study the oscillation characteristics of acoustic cavitation bubbles. The bubbles are generated by acoustic cavitation using an ...
Effect of purity levels on the high-temperature deformation characteristics of severely deformed titanium
(Springer International Publishing, 2017)
In the present investigation, high-temperature compression tests were conducted at strain rates of 0.001 to 0.1 s−1 and at temperatures of 873 K to 1173 K (600 °C to 900 °C) in order to study the hot deformation characteristics ...
Characterization of nano-scale protective oxide films: application on metal chemical mechanical planarization
(The Electrochemical Society, 2015)
This study focuses on the characterization of nano-scale metal oxide films for chemical mechanical planarization (CMP) applications. The protective nature of the self-grown metal oxide layers in the CMP slurry environment ...
