Coupled Rotary and Oscillatory Motion in a Second-Generation Molecular Motor Pd Complex

Lukas Pfeifer

Molecular machines offer many opportunities for the development of responsive materials and introduce autono-mous motion in molecular systems. While basic molecular switches and motors carry out one type of motion upon being exposed to an external stimulus ...

Alternative, Magnetically-Levitated Motor Topologies for High Speed

A slotless magnetically-levitated high speed motor had been designed and build prior to the beginning of this project. This report presents the work done to develop a slotted alternative design to this motor. In this study, the principle of magnetically-le ...

High Stiffness Bearingless Motor

At LAI, a micro bearingless motor system is being developed, in collaboration with a Swiss company. The developed motor must support vibrations, axial and tilting loads. Given the millimetric scale of the motor, a proper bearing design is of paramount impo ...

Validation by Measurements of a Windage Losses Model for Very-High-Speed Machines

Yves Perriard, Douglas Martins Araujo, Guillaume Paul-André Burnand

When designing a very-high-speed (VHS) machine, it is crucial to evaluate the windage losses accurately, because they are an important part of the total losses. It is therefore important to validate a reliable model, further used for the design and optimiz ...

A low-cost method to assess the epidemiological importance of individuals in controlling infectious disease outbreaks

Marcel Salathé

Infectious disease outbreaks in communities can be controlled by early detection and effective prevention measures. Assessing the relative importance of each individual community member with respect to these two processes requires detailed knowledge about ...

Analyse et mise en oeuvre d'un moteur électromagnétique microfabriqué

Sebastiano Merzaghi

Until now, the preferred solution for MEMS (Micro Electro Mechanical Systems) actuation is the electrostatic one. The main reason is that this kind of actuators can be easily manufactured following the microfabrication rules, as their geometry perfectly fi ...
