Accurate and fast detection of harmonics is the basis for active filters to work regularly. Propose an improved generalized IP-IQ harmonic detection algorithm. Analyzed generalized IP-IQ harmonic detection algorithm, pointed out two advantages of this algorithm: It can separate any order of harmonic and detect harmonic correctly even if the voltage of grid is distorted. But the generalized IP-IQ algorithm...
A geometry-based stochastic scattering model (GBSSM) combining of multi-rings and multi-ellipses model for wideband multi-input multi-output (MIMO) vehicle-to-vehicle (V2V) fading channels is developed in this paper with cross polarized antennas. The proposed model can be applied for the line-of-sight (LOS) and non-LOS (NLOS) scenarios. The channel implementation described in this paper is more concise...
In order to study the characteristics of electroencephalogram (EEG) induced by different types of music, we selected 58 volunteers (college students) with no musical training experience. Half of them are males and the rest are females. We finally adopted 49 experimental samples for further data processing. The results showed that: (1) music caused the changes of energy intensity in specific area of...
As pulse can reflect states of the circulatory system and internal organs, pulse diagnosis plays an important role in Traditional Chinese Medicine. This paper proposes an intelligent system to detect the pulse signal and display it on Android smart phone. It uses the Android Bluetooth API to achieve basic operations on the phone terminal and transmits data via the Socket connection. Android smart...
We experimentally studied the photocurrent of AlAs/GaAs/AlAs double barrier resonant tunneling diode (RTD), which is composed of an InAs layer of self-assembled quantum-dots (QDs) on top of the AlAs barrier layer. It is found that the charging InAs quantum dots can effectively modulate the carrier transport properties of the RTD. Moreover, we also found that the resonant tunneling current through...
When the capsule endoscope (CE) is travel along the gastrointestinal tract, its position and orientation are always change. In order to continuously transmit enough power to the device, a wireless energy transmission system using Helmholtz transmitting coil and three-dimensional (3-D) receiving coil is introduced in this paper. Helmholtz coil is driven to generate a uniform alternating magnetic field...
Clinical Decision Support System (CDSS), which importance has already been widely recognized, could improve the safety and quality of clinical diagnosis and treatment. Digitized clinical guidelines play a kernel role in CDSS. Arden syntax for Medical logic modules suggested by the HL7 is the most open and mature clinical guidelines language and widely applied. However, Arden syntax only focused on...
