THE EQUITABLE TOTAL CHROMATIC NUMBER OF THE GRAPH $HM(W_n)$
Wang, Haiying,Wei, Jianxin 한국전산응용수학회 2007 Journal of applied mathematics & informatics Vol.24 No.1
The equitable total chromatic number ${\chi}_{et}(G)$ of a graph G is the smallest integer ${\kappa}$ for which G has a total ${\kappa}$-coloring such that the number of vertices and edges in any two color classes differ by at most one. In this paper, we determine the equitable total chromatic number of one class of the graphs.

3,3'-[1,2-ethanediylbis (oxy-2,1-ethanediyl)]-bis[1-methyl-imidazolium]-dibromide (DImDBr), a gemini imidazolium ionic liquid, was synthesized for the modification and dyeing promotion of poly(ethylene terephthalate) (PET) filaments. The results showed that parameters such as treatment temperature, time, and DImDBr concentration played a critical role on the tensile strength and tensile strength retention of modified PET filaments. The optimal treatment parameters of the PET filaments were 120 ℃ for 90 min with addition of 6 % ionic liquid. The influence of disperse dyeing parameters (temperature, time, and dye concentration) on DImDBr modified PET filaments were also studied. The disperse dyed PET filaments (after treatment with DImDBr) exhibited a desirable color strength (K/S value), excellent soap washing fastness, light fastness, and rubbing fastness. Furthermore, the native PET filaments and DImDBr treated PET filaments werecharacterized by FT-IR, XRD, DSC, TGA, and SEM. Density functional theory (DFT) simulation showed the presence of two kinds of hydrogen bonds (C-H/O and O-H/Br) and eight strong hydrogen bonds in the DImDBr/cis-PET monomers, while only three hydrogen bonds were found in the DImDBr/trans-PET monomers. The structural transformation from the crystalline phase to the amorphous phase (FT-IR, XRD, and DFT simulation) after DImDBr modification confirmed thedyeing promotion of PET filaments at lower temperature.

With the development of electric vehicle electronic control unit (ECU) for vehicle control technology and the key to raise the level of design electric vehicles the optimization control of the vehicle performance as direction. In order to achieve the rational, coordination of vehicles within the system of integrated control, based on the modular thought, through constructing the distributed control network design overall structure of the control system of pure electric vehicle, the vehicle controller is analyzed on the working principle and its function realization degree, as a pure electric vehicle control system provides the theory basis for performance evaluation.
Electromagnetic Analysis and Optimization for a Dual-Rotor Switched Reluctance Machine
Xing Wang,Rui Nie,Hao Chen,Haiying Wang,Tong Xu 한국자기학회 2019 Journal of Magnetics Vol.24 No.2
A dual-rotor switched reluctance motor is proposed in this paper. The structure and working principle of the motor are introduced in detail. The structural parameters have great influence on the performance of the motor, so sensitivity analysis of several important structural parameters to the output torque is carried out based on the two-dimensional finite element method, which improves the average torque of the rotor in the outer air gap. Additionally, the performance of the motor with various pole distributions is analyzed and compared. The results show that when the magnetic polarity distribution of the outer stator is NSNSNSNSNSNS and the magnetic polarity distribution of the inner rotor is NSNSNS, the motor has the best performance. The torque of the motor is compared with that of the traditional single-rotor switched reluctance motor. It shows that the performance of the motor proposed in this paper is better.
