Survivability of integrated PVDF film sensors to accelerated ageing conditions in aeronautical/aerospace structures

Alain Schorderet, Joël Cugnoni, Enrique René Guzman Solares

This work validates the use of integrated polyvinylidene fluoride (PVDF) film sensors for dynamic testing, even after being subjected to UV-thermo-hygro-mechanical accelerated ageing conditions. The verification of PVDF sensors' survivability in these envi ...

Real-time Optimized Rendezvous on Nonholonomic Resource-Constrained Robots

Alcherio Martinoli, Sven Adrian Gowal

In this work, we consider a group of differential-wheeled robots endowed with noisy relative positioning capabilities. We develop a decentralized approach based on a receding horizon controller to generate, in real-time, trajectories that guarantee the con ...

State Estimation for Legged Robots - Consistent Fusion of Leg Kinematics and IMU

Roland Siegwart, Marco Hutter

This paper introduces a state estimation framework for legged robots that allows estimating the full pose of the robot without making any assumptions about the geometrical structure of its environment. This is achieved by means of an Observability Constrai ...

Discovering relevant spatial filterbanks for VHR image classification

Devis Tuia

In very high resolution (VHR) image classification it is common to use spatial filters to enhance the discrimination among landuses related to similar spectral properties but different spatial characteristics. However, the filters types that can be used ar ...

A low power, low chip area decimation filter for Σ - Δ modulator for flywheel MEMS gyro realized in the CMOS 180 nm technology

Pierre-André Farine, Rafal Tomasz Dlugosz, Steve Tanner, Patrick Stadelmann

The paper presents a low power and low chip area decimation filter for a 15-bits Σ-Δ analog-to-digital converter (ADC) designed for a flywheel MEMS gyroscope. In contrary to typical solutions, in which decimation is performed after each filtering stage, in ...

A 2.4 GHz MEMS based sub-sampling receiver front-end with low power channel selection filtering at RF

Christian Enz, Aravind Prasad Heragu Singaiyengar

A sub-sampling RF front end which exploits the intrinsically high quality factor of MEMS devices for performing channel filtering directly at RF is proposed in this work. This narrow band filtering at RF also acts as a good anti-aliasing filter to support ...

Precise frequency and bandwidth control of switchable microstrip bandpass filters using diode and microelectro-mechanical system technologies

Julien Perruisseau-Carrier

In this study, two reconfigurable bandpass filters are presented. The first filter is able to switch between WiFi and universal mobile telecommunications (UMTS) transmit band standards. Centre frequency, bandwidth and power specifications are precisely met ...

Sampling and reconstructing spatial fields using mobile sensors

Martin Vetterli, Jayakrishnan Unnikrishnan

The classical approach to sampling time-invariant spatial fields uses static sensors distributed over space. We study a new approach involving mobile sensors that move through space measuring the field values along their paths. A single moving sensor can t ...

Efficient Schemes for Adaptive Frequency Tracking and their Relevance for EEG and ECG

Jérôme Sébastien Van Zaen

Amplitude and frequency are the two primary features of one-dimensional signals, and thus both are widely utilized to analysis data in numerous fields. While amplitude can be examined directly, frequency requires more elaborate approaches, except in the si ...

Improving the Performance of the FFT-based Parallel Code-phase Search Acquisition of GNSS Signals by Decomposition of the Circular Correlation

Pierre-André Farine, Cyril Botteron, Jérôme Leclère

This paper proposes alternative architectures to perform a circular correlation using the Fast Fourier Transform (FFT) by decomposing the initial circular correlation into several smaller circular correlations. The approach used is similar to the Fast Fini ...
