摘要:Abstract.(#br)The cyclic evolution of a spin-1 system is studied under thespin-spin interaction between the transverse and the longitudinalstates. The eigenstates of the systems are obtained bygeneralized and extended Jordan-Wigner transformation with anangle φ described the...

摘要:Abstract(#br)Water produced by advanced treatment of a groundwater was evaluated to determine the amount of DBPs (Disinfection By-Products) including trihalomethanes (THMs). Both Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GS/MS) were adopted for detection a...

摘要:This article proposes a novel closed-loop rotor flux observer to estimate the rotor flux and velocity of induction motors. With the proposed algorithm, the accuracy of the estimated flux is guaranteed when the estimated stator current converges to its actual one. With the help of...

摘要:This article presents an adaptive rotor flux position observer. Compared with the traditional machine equation based observer, the salient advantage of this method is that it does not need the information of any machine parameter. Thus, potential performance deterioration due to ...

摘要:Abstract(#br)In sour environments containing H2S and water, the casing and tubing yield failure criterion is no longer used because environmental fracture is the main failure mode. In this case, a reasonable material selection and design of casing and tubing can reduce...

摘要:Crossbred wethers (n= 18, 7.5 month of age and 31 ±0.8 kg) were used in a 23-day experiment to determine effects of ad libitum consumption of diets differing in proportions of coarsely chopped bermudagrass and ryegrass-wheat hay (0, 33, 67 and 100%) on oxygen consumption by ...
