A sensitive, stability-indicating reversed-phase high-performance liquid chromatography with diode array detection (HPLC–DAD) method has been developed for the determination of TBI-166 and its 10 kinds of related impurities. Chromatographic separation was achieved on a Kromasil ODS column (250 mm × 4.6 mm, 5 μm), with a gradient elution of the mobile phase system consisting of acetonitrile and 1%...
Impulse-Radio Ultra Wideband (IR-UWB) is a promising technology for indoor localization due to its robustness against multipath interference. In this paper, to deal with the synchronization requirement among anchors in traditional time-difference-of-arrival (TDOA) localization, which is difficult to achieve, an asynchronous time-difference-of-arrival (TDOA) localization method is proposed. The theoretical...
In this paper, we will use a method of analytical calculation to identify a class weakly nonlinear dynamic system. Based on Volterra theory, the aim is to identify its first-order and second-order Volterra kernels. A model of such kind of nonlinear systems described by Riccati equation will be used to illustrate this method below.
