Speech-based assessment of PTSD in a military population using diverse feature classes
We analyzed recordings of the Clinician-Administered PTSD Scale (CAPS) interview from military personnel diagnosed as PTSD positive versus negative.

Cross-corpus depression prediction from speech
We study a new corpus of patient-clinician interactions recorded when patients are admitted to a hospital for suicide risk and again when they are released.

The Effect of the Earth’s and Stray Magnetic Fields on Mobile Mass Spectrometer Systems
Development of small, field-portable mass spectrometers has enabled a rapid growth of in-field measurements on mobile platforms. In such in-field measurements, unexpected signal variability has been observed by the authors…

Mechatronic Design of an Integrated Robotic Hand
In this paper, we present a hand designed for minimalistic dexterous manipulation, in which every stage of the design process also considered its manufacturing cost. Finally, we present the results…

Automatic 3D Change Detection for Glaucoma Diagnosis
We propose an automatic approach for detecting these changes in 3D models reconstructed from fundus images of the same patient taken at different times.

Direction-Changing Fall Control of Humanoid Robots: Theory and Experiments
In this paper we present a strategy to change the default fall direction of a robot, during the fall. By changing the fall direction the robot may avoid falling on a…
