On the calibration aspects of MEMS-IMUs used in micro UAVs for sensor orientation

Jan Skaloud, Philipp Clausen

We introduce a three step procedure to improve attitude determination by MEMS-IMU sensors on board a small UAV. IMU pre-calibration is performed first and only once in the lab; second in a simplified version and for every switch-on in the field. Together, ...

A three-dimensional macroelement for modelling the in-plane and out-of-plane response of masonry walls

Katrin Beyer, Francesco Vanin, Andrea Penna

The seismic performance of unreinforced masonry buildings is commonly assessed using equivalent frame modelling. Its computational efficiency allows for a large number of analyses to be conducted, which are often required to account for epistemic and aleat ...

Resonant Pzt Mems Mirror With Segmented Electrodes

Paul Muralt, Ramin Matloub Aghdam, Mohssen Moridi

We report a transduction optimization method of piezo-based MEMS structures using segmentation of the excitation electrodes. Optimal transduction is achieved by matching the electric field distribution to the polarization distribution including the direct ...

Seismic Behavior of Pine Flat Concrete Gravity Dam Using Microplane Damage-Plasticity Model

Giovanni De Cesare, Pedro Filipe De Almeida Manso, Samuel Luke Vorlet

The response of concrete gravity dams under seismic loads is a major concern of dam safety assessment in earthquake-prone areas. This study focuses on the seismic analysis of the tallest non-overflow monolith of Pine Flat Dam. The paper presents results of ...

Real-world speed estimation using single trunk IMU: methodological challenges for impaired gait patterns

Kamiar Aminian, Anisoara Ionescu, Abolfazl Soltani

Walking speed (WS) is recognized as an important dimension of functional health and a candidate endpoint for clinical trials. To be adopted as a powerful outcome measure in clinical assessment, WS should be estimated pervasively and accurately in the real- ...

Assessment of Real-World Running With Lab-Validated Algorithms Based on Foot-Worn Inertial Sensors

Mathieu Pascal Falbriard

Following the cultural revolution of the late 1960s, the number of elite and recreational runners rose consistently, reaching approximately 7.9 million road races participants in 2018. Today, running is everywhere. City parks, forests, mountain trails, and ...

Synergistic ICRH and NBI Heating for Fast Ion Generation and Maximising Fusion Rate in Mixed Plasmas at JET

Henri Weisen

The studies of recent JET experiments in H/D approximate to 0.85/0.15 plasma (2.9T/2MA) in which neutron rate was enhanced by applying 2.5MW of ICRH using D-(D-NBI)-H three-ion scheme are reported. An extensive analysis of this novel heating scenario has b ...

MEMS Piezoelectric Accelerometer for Vibration Sensing in Harsh Environments

Bradley James Petkus

This master thesis presents a detailed overview of various MEMS accelerometers used as vibrometers in harsh environments. Commercial and scientific literature accelerometers are compared to determine the best accelerometer for said application. This compar ...

Behavioural compass: animal behaviour recognition using magnetometers

Kamiar Aminian, Pritish Chakravarty, Maiki Maalberg

Animal-borne data loggers today often house several sensors recording simultaneously at high frequency. This offers opportunities to gain fine-scale insights into behaviour from individual-sensor as well as integrated multi-sensor data. In the context of b ...
