Spatially resolved skin friction velocity measurements using Irwin sensors: A calibration and accuracy analysis

Michael Lehning, Katherine Colby Leonard, Benjamin Andreas Walter

This study investigates the accuracy of spatially resolved skin friction velocity ut measurements using a large number of Irwin sensors (Irwin, 1981). A fast and simple procedure to calibrate the sensors against a two-component hot-film anemometer is intro ...

A Practical Technique for Accurately Modeling reconfigurable Lumped Components in Commercial Full-Wave Solvers [EurAAP Corner]

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

A practical approach for accurately modeling reconfigurable lumped components, such as semiconductor diodes or micro-electromechanical systems (MEMS), in commercial full-wave solvers is presented. First, an equivalent-circuit model is extracted from a cali ...

Minimizing calibration time of single-trial recognition of error potentials in brain-computer interfaces

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano, Inaki Asier Iturrate Gil

One of the main problems of both synchronous and asynchronous EEG-based BCIs is the need of an initial calibration phase before the system can be used. This phase is necessary due to the high non-stationarity of the EEG, since it changes between sessions a ...

Optomechanical Coupling in a Two-Dimensional Photonic Crystal Defect Cavity

Tobias Kippenberg, Emanuel Gavartin

Periodically structured materials can sustain both optical and mechanical modes. Here we investigate and observe experimentally the optomechanical properties of a conventional two-dimensional suspended photonic crystal defect cavity with a mode volume of s ...

An oedometer for studying combined effects of temperature and suction on soils

Lyesse Laloui, Bertrand François

This paper reports the development of an advanced thermo-hydro-mechanical (THM) oedometer in order to characterize the behavior of soils under combined non-isothermal and unsaturated conditions. The simultaneous control of temperature, suction and stress s ...

Why hydrological predictions should be evaluated using information theory

Steven Vincent Weijs, Nicolaas Cornelis van de Giesen

Probabilistic predictions are becoming increasingly popular in hydrology. Equally important are methods to test such predictions, given the topical debate on uncertainty analysis in hydrology. Also in the special case of hydrological forecasting, there is ...
