Characteristic rupture height of the mediating air film beneath an impacting drop on atomically smooth mica
John Martin Kolinski, Ramin Kaviani
Before a droplet can contact a surface during impact, it must first displace the air beneath it. Over a wide range of impact velocities, the droplet first squeezes the air into a thin film, enhancing its resistance to drainage; this slows the progress of t ...
College Pk2023Rapid Elastic Contact: Image Processing and the Virtual Frame Technique (VFT)
A central air bubble is observed to be maintained during the process of an elastic hemi-sphere impacting on a smooth rigid surface. The similar phenomenon has been found in droplet impact in other studies. The effect of air gap between the two solids has b ...
2020Evidence of extensive lunar crust formation in impact melt sheets 4,330 Myr ago
Accurately constraining the formation and evolution of the lunar magnesian suite is key to understanding the earliest periods of magmatic crustal building that followed accretion and primordial differentiation of the Moon. However, the origin and evolution ...
2020Analysis of volumetric mass transfer coefficient (k(L)a) in small- (250 mL) to large-scale (2500 L) orbitally shaken bioreactors
Florian Maria Wurm, David Hacker, Likuan Zhu
In this study, the combination of dimensional analysis (DA) and analysis of variance (ANOVA) was used to predict the volumetric mass transfer coefficient (k(L)a) values under different operating conditions for orbitally shaken bioreactors (OSRs) with diffe ...
SPRINGER HEIDELBERG2020The sediment challenge of Swiss river corridors interrupted by man-made reservoirs
Giovanni De Cesare, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet, Christian Mörtl
Depending on their characteristics and management, man-made reservoirs can have a significant impact on the natural sediment continuity of rivers. We classify different reservoir types and describe potential risks for the dam and downstream river reach. Ou ...
CRC Press2020Shock-produced high-pressure (La, Ce, Th)PO4 polymorph revealed by microstructural phase heritage of monazite
The responses of uranium-bearing accessory minerals to shock metamorphism have received growing interest, because under extreme pressure and temperature conditions, these phases can form unique microstructures and/or polymorphs and their radiometric ages c ...
GEOLOGICAL SOC AMER, INC2019Hypervelocity impact testing on stochastic and structured open porosity cast Al-Si cellular structures for space applications
A hypervelocity (6.7–7.0 km/s) impact testing campaign was conducted using Ø 2 mm, 95% Al projectiles onto A357 aluminium alloy stochastic foams with 4–5 mm typical pore dimensions, or alternatively diamond cubic periodic structures of cast AlSi12 with a 6 ...
2018Stable Transitions from Free-space to Contact: A Dynamical System Based Approach
Aude Billard, Seyed Sina Mirrazavi Salehian
In this work, we propose a dynamical system based strategy for establishing a stable contact with convex shaped surfaces during non-contact/contact scenarios. A contact is called stable if the impact occurs only once and the robot remains in contact with t ...
2018Transitioning with confidence during contact/non-contact scenarios
Aude Billard, Nadia Barbara Figueroa Fernandez, Seyed Sina Mirrazavi Salehian, Hsiu-Chin Lin
In this work, we propose a dynamical system based strategy for establishing a stable contact with convex shaped surfaces during non-contact/contact scenarios. A contact is called stable if the impact occurs only once and the robot remains in contact with t ...
In Proceedings of the Workshop on Towards Robots that Exhibit Manipulation Intelligence.2018A Dynamical System Based Approach for Controlling Robotic Manipulators During Non-contact/Contact Transitions
Aude Billard, Seyed Sina Mirrazavi Salehian
Many daily life tasks require precise control when making contact with surfaces. Ensuring a smooth transition from free motion to contact is crucial as incurring a large impact force may lead to unstable contact with the robot bouncing on the surface, i.e. ...
