This paper studies the amplitude-frequency characteristic of frontal steady-state visual evoked potential (SSVEP) and its feasibility as a control signal for brain computer interface (BCI). SSVEPs induced by different stimulation frequencies, from 13 ~ 31 Hz in 2 Hz steps, were measured in eight young subjects, eight elders and seven ALS patients. Each subject was requested to participate in a calibration...
Multilevel resistance switching characteristics of the thin FeOx-transition layer were studies by controlling the maximum current compliance during set process. It is obtained that the LRS is mainly influenced by the compliance current value, which is nearly independent to the HRS. Moreover, statistics of set and reset electrical parameters show that the possible switching process is localized, and...
Multilevel resistance switching characteristics of the thin FeOx-transition layer were studies by controlling the maximum stopped voltage during reset process. It is obtained that the HRS is mainly influenced by the stopped voltage value, which is nearly independent to the LRS. Moreover, statistics of set and reset electrical parameters show that the possible switching process is localized, and also,...
