Inter-Joint Coordination Deficits Revealed In The Decomposition Of Endpoint Jerk During Goal-Directed Arm Movement After Stroke, Jozsef Laczko, Robert A. Scheidt, Lucia Simo, Davide Piovesan Jul 2017

Inter-Joint Coordination Deficits Revealed In The Decomposition Of Endpoint Jerk During Goal-Directed Arm Movement After Stroke, Jozsef Laczko, Robert A. Scheidt, Lucia Simo, Davide Piovesan

Biomedical Engineering Faculty Research and Publications

It is well documented that neurological deficits after stroke can disrupt motor control processes that affect the smoothness of reaching movements. The smoothness of hand trajectories during multi-joint reaching depends on shoulder and elbow joint angular velocities and their successive derivatives as well as on the instantaneous arm configuration and its rate of change. Right-handed survivors of unilateral hemiparetic stroke and neurologically-intact control participants held the handle of a two-joint robot and made horizontal planar reaching movements. We decomposed endpoint jerk into components related to shoulder and elbow joint angular velocity, acceleration, and jerk. We observed an abnormal decomposition pattern ...


Repairable Replication-Based Storage Systems Using Resolvable Designs, Oktay Olmez, Aditya Ramamoorthy Jan 2012

Repairable Replication-Based Storage Systems Using Resolvable Designs, Oktay Olmez, Aditya Ramamoorthy

Electrical and Computer Engineering Conference Papers, Posters and Presentations

We consider the design of regenerating codes for distributed storage systems at the minimum bandwidth regeneration (MBR) point. The codes allow for a repair process that is exact and uncoded, but table-based. These codes were introduced in prior work and consist of an outer MDS code followed by an inner fractional repetition (FR) code where copies of the coded symbols are placed on the storage nodes. The main challenge in this domain is the design of the inner FR code. In our work, we consider generalizations of FR codes, by establishing their connection with a family of combinatorial structures known ...
