Accurate and stable reduction of RLC networks using split congurence transformations
(1996)RLC (resistor, inductor, capacitor) network reduction refers to the formulation of small networks whose port behavior is similar to that of large RLC networks. The motivation for this research is that circuits are switching ... -
Activity Recognition for Trans-Tibial Prosthesis Users
(2013-07-25)Prosthetists and medical researchers often find it difficult to assess the results of specific prosthesis prescriptions or therapies, which causes difficulties in medical decisions regarding an amputee. Currently, subject ... -
Adaptation for Brain-Computer Interfaces
(2014-04-30)Brain-computer interface (BCI) technology is evolving rapidly, and shows promise for restoring and even augmenting dextrous control of movement. Recent studies have demonstrated control of robotic arms and computer cursors ... -
Adaptive Wireless Power for Ventricular Assist Devices
Every device needs power to function. Whether that device is a cell-phone, laptop, wearable device, or even a robot, if the power source dies then the device is unusable until charged up again. In our world today, this is ... -
Advanced Clocking and Power Management Techniques for Microprocessors
Ensuring high performance and low-power is the goal for almost all system-on-chips~(SoCs). With the recent slow-down in technology scaling, innovations in circuits and systems are playing a significant role to improve the ... -
