25 The purpose of this study was to quantify how volitional control of hip torque relates to 26 walking function post-stroke. Volitional phasing of hip flexion and extension torques was 27 assessed using a load-cell-instrumented servomotor drive system in 11 chronic stroke subjects 28 and 5 age-matched controls. Hips were oscillated from approximately 40 degrees of hip flexion 29 to 10 degrees ...

Ground Based Augmentation Systems (GBAS), such as the U.S. Local Area Augmentation System (LAAS) can be used for both precision approach and Differentially Corrected Positioning Service (DCPS) applications. Through its support of DCPS, the LAAS Ground Facility (LGF) is required to meet the integrity requirements of all other operations that could use the GBAS VHF Data Broadcast (VDB). Our previ...

Hallux rigidus is a “stiff big toe joint”. Patients with this condition, which is a form of arthritis, often report that it feels as if they have to force their big toe to bend at the joint when “toeing off” from the ground while walking. Often times, hallux rigidus results in the joint becoming completely rigid. Movement of the big toe joint occurs typically in an up and down plane only. The u...

A novel object movement tracer using high order correlation analysis of optical detector array signals is introduced. The optical detectors are arranged nonparallel and the movement loci is estimated by a set of detected signal delays and geometrical position of the detectors. This system is applicable to general robotic movement detection because: 1) It employs a noncontact measurement method,...

Performance in sensory-motor behaviors guides our understanding of many of the key computational functions of the brain: the representation of sensory information, the translation of sensory signals to commands for movement, and the production of behavior. Eye movement behaviors have become a valuable testing ground for theories of neural computation because the neural circuitry has been well c...

The Sichuan-Tibet grid connection project is a national key project implemented in accordance with the developmental needs of Tibet and the living requirements of 700 thousand local residents. It is the first grid project with special high voltage that passes through eastern margin of the Tibetan Plateau. The ground deformation due to widely distributed landslides and debris flow in this area i...
