Product Returns in Closed Loop Demand Chains
… now driving the need to better manage returns. A closed loop supply chain is a supply chain that is designed to consider the acquisition and return flows of products, reuse activities, and the distribution of the recovered products. A ""demand chain"" focuses on what the customer wants and needs, …

Moving fast : neural constraints in closed loop
The generation of fast movements during sensorimotor control is fundamentally limited by the biophysics of neural activity and the physiological dynamics of the muscles involved. Yet, the limiting factors and the corresponding tradeoffs have not been rigorously quantified. We use feedback control …

Closed-loop auditory-based representation for robust speech recognition
A closed-loop auditory based speech feature extraction algorithm is presented to address the problem of unseen noise for robust speech recognition. This closed-loop model is inspired by the possible role of the medial olivocochlear (MOC) efferent system of the human auditory periphery, which has …
