This paper explores and studies recommendation technologies based on content filtering user collaborative proposes a hybrid algorithm filtering. method not only makes use of the advantages but also can carry out similarity matching for all items, especially when items are evaluated by any user, which be filtered recommended to users, thus avoiding problem early level. At same time, this takes advantage When number users evaluation levels large, rating data matrix prediction will become...
This paper presents the design, fabrication, and characterization of a middle-infrared (MIR) linear variable optical filter (LVOF) thermopile detectors that will be used in miniaturized mixed gas detector for CH4/CO2/CO measurement. The LVOF was designed as tapered-cavity Fabry-Pérot filter, which can transform MIR continuous spectrum into multiple narrow band-pass spectra with peak wavelength variation. Multi-layer dielectric structures were to fabricate Bragg reflectors on both sides...
Many researchers believe that crystallization is responsible for drastic viscosity changes near the break temperature of mould flux; however, there are no reasonable experimental data to support this view. In study, complete process recorded in situ by inhibiting volatilization fluoride, and relationship between change studied. Mould flux with a basicity 0.65 had temperature, occurs within range test. The other three fluxes begin crystallize before but crystal volume fractions at different....

High frequency surface acoustic wave (SAW) technology offers many opportunities for aerospace applications in passive wireless sensing and communication. This paper presents the design, simulation, fabrication, test of an L-band SAW resonator based on 128° Y-X LiNbO3 substrate. The design parameters were optimized by finite element (FEM) method coupling-of-mode (COM) theory. Electron-beam lithography (EBL) was used to fabricate submicron-scale interdigital transducers (IDTs) grating...

This article introduces a real-time Bayesian estimation algorithm aimed at enhancing the spin readout efficiency of nitrogen vacancy (NV) center ensemble in diamond. By integrating both prior probability distribution and fluorescence likelihood function, stemming from implementation NV dynamics model, we offered an innovative solution to surpass Cramer–Rao lower bound variance improve efficiency. The proposed was experimentally realized by combining high-performance acquisition processing...
An H⁺-ion sensor based on a gated lateral bipolar junction transistor (BJT) pair that can operate without the classical reference electrode is proposed. The device special type of ion-sensitive field-effect (ISFET). Classical ISFETs have advantage miniaturization, but they are difficult to fabricate by single fabrication process because bulky and brittle materials. Moreover, electrodes need be separated from in some cases. proposed composed two BJT components, one which had silicide layer...
Self-driven ultraviolet photodetectors based on wide-bandgap semiconductors have been well investigated but are still being explored for further performance enhancement. Here we report a self-driven electrochemical photodetector (EUVPD) using three-dimensional nanostructured photoanode defect-engineered TiO2 nanotube arrays (TNAs) modified with single-walled carbon nanotubes (SWCNTs) to enhance photoelectric performance. The EUVPDs Ar-annealed TNAs 0.1 mg/mL of SWCNTs were found higher...
