In order to study the influence of electrical collector system of wind farm from the perspective of four typical topological structures of electrical collector system of wind farm, sequential Monte Carlo model is established for reliability evaluation of electrical collector system of wind farm with consideration of multiple faults of wind turbine generator (WTG) and collection circuit in wind farms...
Fourier transform infrared was used to investigate physiological changes in the chemical composition of roots, stems and leaves of Chenopodium ambrosioides L. amended with different manganese concentrations(5, 200, 500, 2000, 5000, 10000 µmol/L) in nutrient solutions. The absorption band heights at 3350 cm-1 and 1642 cm-1 of stem tissues first increased and then decreased, which indicated that the...
Long registration delay and signaling cost restrict the practical deployment of MIP. Proxy Mobile IPv6 has been proposed to overcome limitation of Mobile IP, which can avoid tunneling overhead and support of hosts in the mobility management. In this paper, we propose an extension protocol based on Proxy Mobile IPv6 to reduce the overhead of Local Mobile Anchor and decrease handoff delay. When the...
With the rapid growth of wireless communication technologies and mobile applications, more and more mobile terminals need to access Internet seamlessly. Due to the IP address acts as both identifier and locator for a mobile terminal, it cannot guarantee the service continuity when a mobile terminal keeps moving. An efficient mobility management schemes for a mobile terminal is important. The Host...
At present, the number of Internet subscribers accessing Internet through mobility terminal equipment and other new types is gradually increasing, which shows it's important to develop mobility management protocols in order to provide mobility support for the subscribers. Several protocols were proposed to support IP mobility in the IETF, such as MIPv6, HMIPv6, FMIPv6 and F-HMIPv6. Some performance...
In this paper, we extend the conventional phase-only correlation (POC) technique to the quaternion field (QPOC) and propose a subpixel color image registration algorithm based on the QPOC. Due to mathematical limitations, traditional POC-based registration algorithms can only be applied to grayscale images or at most complex images. A color image must be first converted to a grayscale one before performing...
