Improving Main-memory Database System Performance through Cooperative Multitasking

Georgios Psaropoulos

Database systems access memory either sequentially or randomly. Contrary to sequential access and despite the extensive efforts of computer architects, compiler writers, and system builders, random access to data larger than the processor cache has been s ...

Navigating the validity tradeoffs of entrepreneurship research experiments: A systematic review and best-practice suggestions

Jérémy Binder, Julia Katharina Binder

Experimental methods provide important advantages for advancing academic understanding of entrepreneurship. Yet, the complex and comingled relationships between some of entrepreneurship's key characteristics pose thorny methodological challenges to entrepr ...

Hypervelocity impact testing on stochastic and structured open porosity cast Al-Si cellular structures for space applications

Andreas Mortensen

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 ...

Stable 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 ...

A 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. ...

Electrospun nanofibrous interleaves for improved low velocity impact resistance of glass fibre reinforced composite laminates

Véronique Michaud, Amaël Maximilien Cohades, Lode Geeraard Daelemans

This study analyses the damage tolerance of nanofibre interleaved composites when subjected to low velocity impact. Cross-ply glass/epoxy composite laminates are produced. Drop-weight impact and residual compressive strength measurements are performed on t ...
