OpenArm: Volumetric & Time Series Models of Muscle Deformation

The OpenArm data sets are designed to enable study
of force- and kinematic-induced muscle deformation
for applications in biomechanics research,
computer graphics, and assistive device
development. **NEW:** The OpenArm Multisensor
2.0 data set contains new time series of
ultrasound-measured brachioradialis deformation,
surface electromyography (sEMG)-measured
activation, force, and goal trajectory data, for
various force-, deformation-, and activation-based
trajectory tracking tasks, under refined
conditions from those of the 1.0 data set. Also
included are all analysis, real-time muscle
deformation tracking, and display code. The
OpenArm Multisensor 1.0 data set contains time
series cross-sectional ultrasound scans of the
brachioradialis muscle under variable elbow
loading, alongside corresponding surface
electromyography (sEMG), acoustic myography (AMG),
and force data. The OpenArm 1.0 and 2.0 data
sets encompass factorial sets of volumetric scans
of the arm, generated using ultrasound and motion
capture, that allow for analysis of both force-
and configuration-associated muscle deformation.

Closed loop simulation of a human-exoskeleton and kinetic and kinematic modeling

This project attempts to tackle some of the
challenges in developing an exoskeleton device
using simulation methods. in this project, the
closed loop simulation of a human exoskeleton is
performed .In this study, a simulation-based
method is presented for the designing and analysis
of the parameters of an exoskeleton and its
wearer’s kinetics and kinematics. Model-based
design software, including OpenSim and Inventor,
and mathematical software, such as MATLAB, are
integrated. This method can assist in the
modification of exoskeleton devices and allow
physiologists, and physical therapists to
generate new solutions for rehabilitation programs
using exoskeletons.

In-silico LADDER: Lung Aerosol Dosimetry for Drug and Environmental Research

The in-silico LADDER project aims at developing
aerosol dosimetry multiscale models through a
modular integration of 3D computational fluid
particle dynamic CT-based lung models of the upper
and large airways with each most distal 3D airway
bi-directionally coupled with lower dimensional
airflow, aerosol transport, and tissue mechanics
models.
