Postural transitions detection and characterization in healthy and patient populations using a single waist sensor

Kamiar Aminian, Farzin Dadashi, Benoît Mariani, Arash Atrsaei

Background: Sit-to-stand and stand-to-sit transitions are frequent daily functional tasks indicative of muscle power and balance performance. Monitoring these postural transitions with inertial sensors provides an objective tool to assess mobility in both ...

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 ...

An Instrumented High-Speed Rotor With Embedded Telemetry For The Continuous Spatial Pressure Profile Measurement In Gas Lubricated Bearings: A Proof Of Concept

Jürg Alexander Schiffmann, Karim Magdi Zakaria Abdelrahman Shalash

Gas lubricated bearings are capable of supporting high speed rotors with satisfactory load capacities. Pressure is one of the constitutional quantities governing the flow field in gas lubricated bearings. Knowledge of the pressure is of principal importanc ...

VIMO: Simultaneous Visual Inertial Model-Based Odometry and Force Estimation

Davide Scaramuzza

In recent years, many approaches to visual-inertial odometry (VIO) have become available. However, they neither exploit the robot's dynamics and known actuation inputs, nor differentiate between the desired motion due to actuation and the unwanted perturba ...

Experimental study on the hydrodynamic impact of tsunami-like waves against impervious free-standing buildings

Anton Schleiss, Michael Pfister, Davide Wüthrich, Ioan Nistor

Tsunamis, landslide-generated waves, and dam failures are rare, but highly destructive phenomena, associated with extreme loading on infrastructure. Recent events showed that specific measures must be taken to guarantee safety of both people and the built ...

Extreme Hydrodynamic impact onto buildings

Davide Wüthrich

Dam failures, impulse waves, tsunamis and storm surges are disasters that challenge humanity, often leading to massive casualties and important economic losses. These events generate highly unsteady flow conditions in the form of surges or turbulent bores, ...

Earthquake-induced floor accelerations in base isolated structure

David Michael Volpe Ruggiero

In order to meet desired seismic performances, it is increasingly evident that engineers require reliable methods for the estimation of seismic demands on both structural and non-structural elements. To this end, current design codes incorporate simplified ...

Bridge natural frequency estimation by extracting the common vibration component from the responses of two vehicles

Arka Prabhata Reksowardojo

Bridge natural frequencies are among fundamental properties of bridges. However, natural frequencies of most bridges remain unknown. Natural frequency identification through acceleration measurement with sensors installed on bridges is not practical if a l ...

Defining a braking probability to estimate extreme braking forces on road bridges

Katrin Beyer, André-Gilles Dumont, Marc-Antoine Fénart, Glauco Feltrin

A probabilistic approach is necessary to estimate the magnitude of the braking force that compares in terms of return period with the vertical traffic loads present in bridge design codes. A data set from a Danish Field Operational Test served as support t ...
