Instantaneous flow vector measurement by a pair of ultrasound doppler instruments

Giovanni De Cesare, Shun Nomura, Jumpei Hitomi

Ultrasound Doppler velocity profiling is an effective method for instantaneous fluid velocity measurement along a measurement line. However, measuring vector components in multiple dimensions requires the development of multiple transducers, with the exact ...

Wall-contact sliding control strategy for a 2D caged quadrotor

Dario Floreano, Przemyslaw Mariusz Kornatowski, Pu Bai

This paper addresses the trajectory tracking problem of a 2D caged flying robot in contact with a wall. To simplify the contact problem, the models are constructed on a vertical two-dimensional plane, and our objective is to let the quadrotor hover or move ...

Evaluating upper limb impairments in multiple sclerosis by exposure to different mechanical environments

Martina Coscia

Multiple sclerosis is a chronic, autoimmune and neurodegenerative disease affecting multiple functional systems and resulting in motor impairments associated with muscle weakness and lack of movement coordination. We quantified upper limb motor deficits wi ...

Development and Comparison of Foot Interfaces for Controlling a Robotic Arm in Surgery

Hannes Bleuler, Mohamed Bouri, Etienne Burdet, Elahe Abdi

Currently available foot interfaces to command an external assistive robotic arm for laparoscopic surgery typically consist of a couple of push buttons placed on a planar platform. In this paper, we develop and compare two foot interfaces implementing isot ...

Morphogenetic degeneracies in the actomyosin cortex

Sundar Ram Naganathan

One of the great challenges in biology is to understand the mechanisms by which morphogenetic processes arise from molecular activities. We investigated this problem in the context of actomyosin-based cortical flow in C. elegans zygotes, where large-scale ...

Dynamic Modeling of Trip Completion Rate in Urban Areas with MFD Representations

Nikolaos Geroliminis, Anastasios Kouvelas, Raphael Ali Francis Lamotte, Mikhail Murashkin

A large part of the research utilizing the concept of Macroscopic Fundamental Diagram (MFD) relies heavily on the PL model, an approximation of the trip completion rate derived for steady states. There exists an alternative method to the PL approximation. ...

Experimental Characterization of a T-Shaped Programmable Multistable Mechanism

Simon Nessim Henein, Mohamed Gamal Abdelrahman Ahmed Zanaty

Programmable multistable mechanisms (PMM) exhibit a modifiable stability behavior in which the number of stable states, stiffness, and reaction force characteristics are controlled via their programming inputs. In this paper, we present experimental charac ...

Design and Evaluation of a Bowden-Cable-Based Remote Actuation System for Wearable Robotics

Roger Gassert, Olivier Lambercy

Wearable robots can assist motor-impaired individuals in activities of daily living, but weight is paramount for usability. Proximally placed actuators and remote actuation systems (RAS) minimize weight on users' extremities. State-of-the-art RAS employ pn ...
