Sintering of NaCl powder: Mechanisms and first stage kinetics

Andreas Mortensen, Jean-François Despois

Isothermal NaCl sintering experiments are conducted between 500 and 790 degrees C on powders 75, 100, 150 and 400 mu m in average diameter. Along with literature data, the results are compared with theoretical predictions for the initial stage of sintering ...

Self-Organized Embedded Sensor/Actuator Networks for ''Smart'' Turbines

Alcherio Martinoli, Nicolaus Correll, Christopher Cianci, Xavier Raemy

Combining networks of static sensors with minimalist robotic swarms might enable a new generation of micromachinery equipped with sensor and actuator networks for inspection, maintenance, and repair. In such a scenario, limited capabilities of swarm member ...

Characterization of supersonic low pressure plasma jets

Malko Gindrat

Low Pressure Plasma Spraying (LPPS) processes use a DC plasma jet expanding at low pressure for fast deposition of dense coatings in a controlled atmosphere. The LPPS technology is widely used industrially in particular in the aeronautics and medical indus ...

Dynamic Group Communication

André Schiper

Group communication is the basic infrastructure for implementing fault-tolerant replicated servers. While group communication is well understood in the context of static systems (in which all processes are created at the start of the computation), current ...

Density measurements of liquid Fe-S alloys at high-pressure

Philippe Gillet

We present the first static measurements of the density of metallic liquids in the Fe-S system in the pressure and temperature range 1.5 GPa-6.2 GPa and 1500 K - 1780 K. Density is inferred from X-ray absorption experiments carried out with a large volume ...

Position control of the center of mass for articulated figures in multiple support

Daniel Thalmann, Ronan Boulic

We extend a recent approach for the position control of the center of mass for any tree structured articulated figure in a multiple support context. Our approach fits into existing high level interfaces of behavioral control of human figures; it brings the ...

Dependence of the direct piezoelectric effect in coarse and fine grain barium titanate ceramics on dynamic and static pressure

Dragan Damjanovic

The direct piezoelectric effect in fine and coarse grain barium titanate ceramics is examined as a function of the external alternating and static pressure. It is found that domain wall vibrations contribute to the piezoelectric effect in both types of cer ...

Improving the accuracy of parallel robots

The main objective of this thesis is the accuracy improvement of parallel robots. Accuracy can be improved either by precise manufacturing and assembly or by calibration of each individual robot using a kinematic model which takes geometric deviations into ...

Experimental flow study of the GAMM turbine model

François Avellan, Mohamed Farhat, Philippe Dupont

An experimental study of flow in a Francis hydraulic turbine, especially designed for the GAMM Workshop, has been carried out. In order to provide a data base for the validation and comparison of computational fluid dynamics codes, a Francis turbine mode! ...

Flow survey and blade pressure measurements in a Francis turbine model

François Avellan, Mohamed Farhat, Philippe Dupont

Experimental flow analysis of hydraulic machines is of prime importance for improving the design of such a unit. Moreover, computational fluid dynamics codes need an experimental data reference in order to check their ability to simulate the main flow feat ...
