In this study a new approach is introduced, which is based on a lock-in measurement of gas fraction modulation.
To reliably detect such small capacitance changes, a low-noise measurement system, based on a lock-in amplifier, is implemented.
UV-Vis spectrophotometer (JASCO, UV-550) and a home-built surface photovoltage (SPV) measurement system based on a lock-in amplifier (Stanford, SR830) were employed to test the optical and photoelectric properties.
Lipofection of an antisense oligonucleotide based on a locked nucleic acids (LNA)/2′- O-methylene mixmer or electroporation of a peptide nucleic acid (PNA) oligomer is effective at blocking miR-122 activity, highlighting the use of miRNA in future therapeutic application.
Reference [3] presents a control method based on the adaptation of a dual second order generalized integrator based on a frequency locked loop (DSOGI-FLL).
These results are compared successfully with reference measurements obtained on the same sample using a conventional experimental setup based on a commercial lock-in amplifier.
This paper discusses the design and fabrication of a high-frequency wide-range frequency synthesizer based on a phase locked loop (PLL), varactorless LC-type voltage-controlled oscillator, and push push frequency doubler.
There is also potential for Unikey to partner with home control and home automation companies in order to trigger certain events in the home based on a door locking or unlocking.
After that, we proposed a two-stage scheme of sampling clock synchronization based on theoretical derivation: the preliminary SFO was jointly acquired with the carrier frequency offset by using the improved preamble-aided algorithm firstly, the timing drift resulted from residual SFO and STE was tracked based on a phase looped lock in the second stage.
Both have been toyed with over a number of previous shorts, and the character of Willy is actually based on a real-life lock keeper from De Swaef's first-year school documentary.
The rotor position and speed estimation method is based on a modified phase-locked-loop (MPLL).
