Abstract: Single-walled carbon nanotubes (SWNTs) are decorated with metal nanoparticles to form high-performance flexible hydrogen sensors. The special process to form the high-performance flexible hydrogen sensors can combine a dry transfer printing technique and modification of SWNTs with palladium (Pd) nanoparticles to provide high-performance hydrogen sensors with excellent mechanical flexibility on plastic substrates. Two approaches can be used to decorate the SWNTs. One is physical deposition, such as electron beam evaporation (EBE) and the other is electrochemical deposition which can selectively grow palladium nanoparticles on the surface of the SWNTs, resulting in significantly decreasing the use of palladium. Preferably, the Pd nanoparticles are deposed on the SWNTs in a discontinuous arrangement so that the Pd nanoparticles are spaced away from each other to form individual discontinuous Pd nanoparticles rather a continuous Pd film.

Information is imprinted in the ferroelectric layer by the polarization induced by the application of a voltage pulse between the top and bottom electrodes through the conductive UNCD tips.

Abstract: It is possible to establish an estimation method capable of logically and optimally deciding a forgetting coefficient and develop an estimation algorithm and a high-speed algorithm which are numerically stable. Firstly, a Processing section reads out or receives an upper limit value ?f from a storage section or an input section (S101). The.processing section decides a forgetting coefficient ? by equation (15) (S103). After this, according to the forgetting coefficient ?, the processing section executes a hyper H? filter of equations (10-13) (S105). The processing section (101) calculates the existence condition of equation (17) (or equation (18) which will be given later) (S107). When the existence condition is satisfied at all the times (S109), ?f is decreased by ?? and the same processing is repeated (S111).
