Fast Traveling Pneumatic Probes for Turbomachinery Applications

Developing large eddy simulation for turbomachinery applications.

For jets, large eddy resolving simulations are compared for a range of numerical schemes with no subgrid scale (SGS) model and for a range of SGS models with the same scheme. There is little variation in results for the different SGS models, and it is shown that, for schemes which tend towards having dissipative elements, the SGS model can be abandoned, giving what can be termed numerical large...

Continuous measurement with traveling-wave probes

We consider the use of a traveling-wave probe to continuously measure the quantum state of an atom in free space. Unlike the more familiar cavity QED geometry, the traveling wave is intrinsically a multimode problem. Using an appropriate modal decomposition, we determine the effective measurement strength for different atom-field interactions and different initial states of the field. These inc...

Pleated Pneumatic Artificial Muscles for Robotic Applications

This work describes the implementation of Pleated Pneumatic Artificial Muscles (PPAM) into innovative robotic applications. These actuators have a very high power to weight ratio and an inherent adaptable compliance. Two applications for which these characteristics give interesting surplus values are described. Nowadays legged robots are gaining more and more interest. But most of the robots us...

Neural Probes for Chronic Applications

Developed over approximately half a century, neural probe technology is now a mature technology in terms of its fabrication technology and serves as a practical alternative to the traditional microwires for extracellular recording. Through extensive exploration of fabrication methods, structural shapes, materials, and stimulation functionalities, neural probes are now denser, more functional an...
