Ultra low-power radio-frequency identification (RFID) tag with precision localization is often the enabling technology for location-aware sensor applications. Impulse-Radio Ultra-Wideband (IR-UWB) is a promising technology to fulfill the usage requirements in indoor cluttered environment. An ultra low-power precise UWB-RFID localization system is proposed(More)
Abstract-In this paper, an ultra wideband impulse radio (UWB-IR) transmitter and receiver monolithic microwave integrate circuit (MMIC) for precision localization sensor network is presented. Longer range is achieved with low power consumption at the transmitter by fully exploiting FCC's peak power constraint efficiently. The transmitter and receiver MMIC(More)
In this research, pulse analysis is performed on the data of 241 subjects collected from Department of Cardiology at Shandong Provincial Hospital in China. By taking the dynamic curve fitting, dicrotic notch is located using the third derivatives of the fitted function. Subendocardial Viability Ratio (SEVR), Systolic Time Index (SPTI), and Diastolic Time(More)
Percutaneous radiofrequency ablation (RFA) is a minimally invasive treatment to thermally destroy tumors. Ultrasound-based electrode-displacement elastography is an emerging technique for evaluating the region of RFA-induced lesions. The angle between the imaging probe and the RFA electrode can influence electrode-displacement elastography when visualizing(More)
The complex molecule in the title compound, [NiBr2(C36H40N2)], has mirror symmetry. The Ni(II) atom and two Br atoms are located on the mirror plane. The Ni(II) atom is four-coordinated by the two Br atoms and two N atoms from an N,N'-bis(2,6-diethyl-4-phenyl-phen-yl)butane-2,3-di-imine ligand in a distorted tetra-hedral geometry. The dihedral angle formed(More)
Burst-mode focused ultrasound (FUS) exposure has been shown to induce transient blood-brain barrier (BBB) opening for potential CNS drug delivery. FUS-BBB opening requires imaging guidance during the intervention, yet current imaging technology only enables postoperative outcome confirmation. In this study, we propose an approach to visualize short-burst(More)
There are some shortcomings in the CVT dynamic performance in the conventional economic model This study increased dynamic performance of vehicle through amending the target speed ratio and the proportional solenoid valve drive signal voltage With the driver's intention(the accelerator opening change rate), we get the driver's intention index. We use the(More)
