We demonstrate the modulation of spin Seebeck effect (SSE) by hydrogenation in Pd/YIG bilayers. In presence 3% hydrogen gas, SSE voltage decreases more than 50% from magnitude observed pure Ar gas. The is reversible, but recovery to prehydrogenation value takes a few days because long time constant desorption. also that Hall magnetoresistance identical sample reduces significantly with exposure...

Finally the paper deals with the solution of the following problem: Let signals y1(iT), ..., yq(iT) (elements of output vector y(iT)) be responses of MIMO discretetime system to the input signals u1(iT),..,uq(iT) (elements of input vector u(iT)). Determine discrete-time excitations uA1,......,uAq (elements of vector uA) scaling the system responses to the required forms y1(iA-1T),...,yq(iA-1T),...

distribution of magnetic fields in the quiet-sun internetwork areas has been affected by weak polarization (in particular stokes q and u) signals. to improve the signal-to-noise ratio (snr) of the weak polarization signals, several approaches, including temporal integrations, have been proposed in the literature. in this study, we aim to investigate a proper temporal-integration time with which...

This paper proposes, investigates, and validates, by comprehensive experiments, new online automatic diagnostic technology for belt conveyor systems based on motor current signature analysis (MCSA). Motor (MCSA) is a method employed detecting faults in electric motors analyzing the waveforms generated during operation. The capitalizes fact that defects, such as mechanical misalignment, bearing ...

Biological organisms have intrinsic control systems that act in response to internal and external stimuli maintaining homeostasis. Human heart rate is not regular and varies in time and such variability, also known as heart rate variability (HRV), is not random. HRV depends upon organism's physiologic and/or pathologic state. Physicians are always interested in predicting patient's risk of deve...
