Crack kinematics prediction in concrete structures and assessment of their criticality
The observation of cracks in normally functioning reinforced concrete (RC) structures is expected as the tensile strength of concrete is relatively low. However, one or more of those cracks can start to propagate with increasing crack openings, localizing ...
2023Piecewise Affine Curvature model: a reduced-order model for soft robot-environment interaction beyond PCC
Josephine Anna Eleanor Hughes, Francesco Stella, Qinghua Guan
Soft robot are celebrated for their propensity to enable compliant and complex robot-environment interactions. Soft robotic manipulators, or slender continuum structure robots have the potential to exploit these interactions to enable new exploration and m ...
IEEE2023Tribological Approach to the Watch Movements
Valentine Agnès Madeleine Magnin
Mechanical watches are complex and sensitive systems that have to maintain a faultless precision over their lifetime. However, this precision can be altered by disturbances occurring during the functioning time, such as friction, lubricant drying, or wear, ...
EPFL2020Postural 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 ...
2020Adaptive Gradient Descent without Descent
We present a strikingly simple proof that two rules are sufficient to automate gradient descent: 1) don’t increase the stepsize too fast and 2) don’t overstep the local curvature. No need for functional values, no line search, no information about the func ...
2020Rigid foldability and mountain-valley crease assignments of square-twist origami pattern
Rigid foldability allows an origami pattern to fold about crease lines without twisting or stretching component panels. It enables folding of rigid materials, facilitating the design of foldable structures. Recent study shows that rigid foldability is affe ...
PERGAMON-ELSEVIER SCIENCE LTD2020SCALAR: Simultaneous Calibration of 2-D Laser and Robot Kinematic Parameters Using Planarity and Distance Constraints
In this paper, we propose SCALAR, a calibration method to simultaneously calibrate the kinematic parameters of a 6-DoF robot and the extrinsic parameters of a 2-D laser range finder (LRF) attached to the robot's flange. The calibration setup requires only ...
2019Patient Motion Using a Computerized Leg Brace in Everyday Locomotion Tasks
Exoskeletal systems are becoming a rehabilitation standard of care for persons with lower limb paralysis. As muscular dysfunctions affect a heterogeneous patient group, each individual develops their own strategy to negotiate everyday locomotion challenges ...
2019Reading from the Black Box: What Sensors Tell Us about Resting and Recovery after Real-World Falls
Lying on the floor for a long time after falls, regardless of whether an injury results, remains an unsolved health care problem. In order to develop efficient and acceptable fall detection and reaction approaches, it is relevant to improve the understandi ...
2018Out-of-plane instability of thin reinforced concrete walls under seismic loading
Out of plane instability of reinforced concrete walls is a failure mechanism observed rather recently following the earthquakes in Chile (2010) and New Zealand (2011). Global out of plane instability is a phenomenon that may occur in thin walls, subjected ...
