Parallel optical readout of cantilever arrays in dynamic mode

Peter Vettiger

Parallel frequency readout of an array of cantilevers is demonstrated using optical beam deflection with a single laser-diode pair. Multi-frequency addressing makes the individual nanomechanical response of each cantilever distinguishable within the receiv ...

Sub-100μW low power operation of vibrating body FETs

Mihai Adrian Ionescu, Daniel Grogg

This paper reports the low power operation of Vibrating Body Field Effect Transistors as active resonators for communication applications. For the first time we report active resonators operating at 2MHz and 20MHz with power consumption less than 100μW and ...

Mechanisms for Making Crowds Truthful

Boi Faltings, Radu Jurca

We consider schemes for obtaining truthful reports on a common but hidden signal from large groups of rational, self-interested agents. One example are online feedback mechanisms, where users provide observations about the quality of a product or service s ...

Towards Probabilistic Estimation of Quality of Online Services

Karl Aberer

Accurate estimation of quality of online services is both an important and difficult problem, since a service has many interdependent quality attributes influenced by several contextual factors. It is even more challenging as quality ratings come from sour ...

Nano-gap high quality factor thin film SOI MEM resonators

Mihai Adrian Ionescu, Dimitrios Tsamados, Daniel Grogg, Marco Mazza, Hüseyin Cumhur Tekin

A 1.25 m thin SOI micro-electro-mechanical (MEM) resonator with a quality factor of 100’000 at 24.6 MHz is demonstrated. A nanogap fabrication process allows the fabrication of < 200 nm gaps, allowing for low polarization voltages. A motional resistance of ...

Delayed Multiattribute Product Differentiation

Thomas Alois Weber

We develop a two-stage model for versioning products with respect to both vertical and horizontal attributes. At first, a firm positions its top-quality “flagship” product in a market with an imperfectly known distribution of tastes and reservation prices. ...
