A homospin ladder-like chain, [Co(Hdhq)(OAc)](n) (1; H(2)dhq = 2,3-dihydroxyquinoxaline), shows a single-chain-magnet-like (SCM-like) behavior with the characteristics of frequency dependence of the out-of-phase component in alternating current (ac) magnetic susceptibilities and hysteresis loops.

We are currently fabricating a haptic interface device to enable direct physical interaction with dynamic simulated three-dimensional environments by exerting and reacting to forces and motions between the user's hand and a magnetically levitated object. Our device uses magnetic levitation rather than a motorized linkage so that the dynamics are simple and actuator nonlinearities such as hyster...

Conjugated polymer actuators can be employed to achieve micro and nano scale precision, and have wide range of applications including biomimetic robots and biomedical devices. In comparison to robotic joints, they do not have friction or backlash, but on the other hand, they have complicated electro-chemo-mechanical dynamics which makes modeling and control of the actuator really difficult. Bes...

The control loop in the industry is a component that must be maintained because it will determine plant's performance. Most industrial controllers experience oscillations with various causes, such as noise, oscillation, backlash, dead band, hysteresis, random variation, and poor controller tuning. oscillation diagnosis system, which can understand type characteristics, built based on machine le...

Public acceptance of utility programs and initiatives is vital for efficient deployment. Consumer complaints, protests, and lawsuits, can significantly impede progress and cost utilities, cities, and taxpayers money. One recent area where this has become clear is the deployment of smart meters. While the advantages of smart meters are widely accepted by utilities, academics, and governments, so...
