The heat of mixing HE for N, N-Diethylethanolamine(DEEA), 1-(2-hydro-xyethyl) piperazine(HEPZ) in water were measured with C-80 calorimeter at two different T=(303.15, 323.15)K and over the entire range of mole fractions. The experimentally measured HE values are correlated as a function of mole fractions using the Red-lich--Kister (RK) equation. And the nonrandom two-liquid (NRTL) parameters were...
Since the dynamic characteristics of the linear ultrasonic motor (LUSM) are highly nonlinear and time varying, it is difficult to design a suitable motor position controller to achieve high-precision position control at all time. An intelligent robust tracking control (IRTC) system employs a dynamics wavelet-based cerebellar model articulation controller (DWCMAC) is developed for LUSMs. The dynamic...
Bayesian network is an uncertainty inference network based on probability. Its structure learning is one of the main research techniques in the field of data mining and knowledge discovering, while constructing Bayesian network structures from data is NP hard. According to the information theory and conditional independence test, a new algorithm is presented for the construction of optimal Bayesian...
The scientific scheduling of maintenance support resources in the war is very important to accomplishing the task of maintenance support, but the finity of maintenance support resources has a demand that the commander of maintenance support must schedule maintenance support resources dynamically. The paper consideres total effect of maintenance support, and takes the current and latent need into account...
The inner and outer diameter of electrostatic phase plate di, dm and do limit the number of electrons passing through and then affect the high-resolution information in the phase contrast image. The current density contours at the upper surface of the phase plate is first used to determine di, dm and do. The current density contours and trajectory of un-scattered electrons under a real objective lens...
The objective of this paper is to research to use a few MEMS (Micro Electron Mechanical System) temperature sensors for measurement and estimation of temperature distribution in the core and cavity of the mold during injection molding process. Decreasing the number of MEMS temperature sensors inside the core and cavity will reduce the cost for making product and still calibrate precisely. In this...
The asymmetrical half bridge flyback converter is gaining popularity because it can achieve ZVS operation. However, the relationship between voltage transfer ratio and duty cycle is nonlinear in the condition of high switching frequency and small blocking capacitor. It is improper to use the linear model to guide the design of asymmetrical half bridge flyback converter. This paper deduces a steady-state...
