The Non-traditional Methods of Robotic Wheelchair Multi-channel Control

The most common way to control a wheelchair is the joystick. However, for some people the joystick control is difficult or impossible for one reason or another. For such people, other (non-traditional) control methods are being developed using methods of robotics. In this article, we consider possible non-traditional control methods that can be used to allow patients control a robotic wheelchair by themselves.     Keywords: robotic wheelchair, multi-channel control, non-traditional control methods, robotic

Spin dynamics and ordering of a cuprate stripe-antiferromagnet

In La1.48Nd0.4Sr0.12CuO4 the 139La and 63Cu NQR relaxation rates and signal wipe-out upon lowering temperature are shown to be due to purely magnetic fluctuations. They follow the same renormalized classical behavior as seen in neutron data, when the electronic spins order in stripes, with a small spread in spin stiffness (15% spread in activation energy). The La signal, which reappears at low temperatures, is magnetically broadened and experiences additional wipe-out due to slowing down of the Nd fluctuations.Comment: 4 pages including 3 figures - ref. 16 adde
