Muscle Control of an Extra Robotic Digit

Advanced Robotics Research, EarlyView.
This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Attenuation Coefficient Measurement in the Thyroid

Journal of Ultrasound in Medicine, 2003
To assess the feasibility of a novel method of measuring the attenuation coefficient in the thyroid, which offers less variability of results than the conventional method.In our new method, the attenuation coefficient was evaluated on the basis of the following equation with sound field correction: alpha = -1/4[Fc(z)-epsilon(z)] x d/dz[log(M0(z))-tau(z)

Attenuation Coefficient Estimation of Normal Placentas

Ultrasound in Medicine & Biology, 2019
Attenuation coefficient estimation has the potential to be a useful tool for placental tissue characterization. A current challenge is the presence of inhomogeneities in biological tissue that result in a large variance in the attenuation coefficient estimate (ACE), restricting its clinical utility. In this work, we propose a new Attenuation Estimation

Investigation of photon attenuation coefficients for marble

Journal of Radiological Protection, 2005
The total linear attenuation coefficients micro (cm(-1)) have been obtained using the XCOM program at photon energies of 1 keV to 1 GeV for six different natural marbles produced in different places in Turkey. The individual contribution of photon interaction processes to the total linear attenuation coefficients for marble has been investigated.

Diffuse attenuation coefficient profiles

IEEE Transactions on Geoscience and Remote Sensing, 1994
Diffuse attenuation coefficient (k/sub d/, k/sub u/) eigenanalysis, using field data, is performed. Data are partitioned into wavelength, province, season, and up/downwelling k. Resulting eigenvectors and scalar multiples allow a reconstruction of the original k profiles. Parameterizing the scalar multiples, using satellite derived surface k's, k depth
