On the basis of the production data from a 50t LD in Jiu Steel a grey system math model is built up by taking the converter steel-making system as a gray system. Further more an optimized program of linear multi-objective plan is worked and the technology conditions for simultaneous optimization of Dephosphorization and Desulphurization in the converters in Jiu Steel determined.
By investigating the influences of grating position and coupler waist’s uniformity, a novel Two-FBGs reflecting coupler with symmetric configuration is designed and fabricated, which can simultaneously optimize add and drop filter characteristics.
This paper presents an evolutionary algorithm to simultaneously optimize constellation structure and parameters for regional coverage satellite constellation design.
A new QoS multicast tree selection algorithm based on Non-dominated Sorting technique of genetic algorithms was presented to simultaneously optimize multiple QoS parameters.
As the determination of such optimal multicast routes was computationally intractable in polynomial time, a multicast routing algorithm based on genetic algorithm was proposed to simultaneously optimize different parameters, in which multiple multicast tree route solutions were generated.
the final pH value of D1 stage, about 3.8. Under this optimized condition, when the total active chlorine charge is 45 kg/t, thebrightness of the pulp can reach 84.1%ISO, viscosity 922ml/g, and the color reversion value 0.89 and the D0 ( EOP) D1 bleached pulp hasexcellent strength properties.
With using 30% hot metal charging while the temperature of metal being no less than 1 300 ℃, and optimizing power supply schedule and foam slag process, the steelmaking power consumption of a 65 t electric arc furnace at Shiheng Special Steel decreased by 95 kWh/t, the Oxygen consumption decreased by 2.8 m 3/t and the tap to tap time reduced by 7.5 min.
The optimization experiment showed that temperature was the most notable factor influencing the hydrogen production quantity. The optimal condition combination of hydrogen production was that temperature was 30℃, light intensity was 1600lx, material pH value was 7.0 and initial activity of PSB was 60 h.
A simultaneous optimization of resolution, efficiency and migration times of enkephalin-related peptides in micellar electrokinetic capillary chromatography (MEKC) was performed.
In addition, the simulator's capability to simultaneously optimize competing movement aspects represents an interesting opportunity for the motor control community, in which the coexistence of several controlled variables has been hypothesized.
This paper describes an efficient optimality criterion method for the optimum design of antenna structure. The algorithm incorporates a set of recursion formulas derived from the necessary conditions for the conditional extreme.It has overcome the limitation of the former criterion method (virtual work approach) which was developed by R. Levy. Moreover, with the Levy method, the design variables are only restricted to the cross-sectional area of members and the geometry of structure is fixed. Both member cr...
This paper presents a general description of the design and construction of a rigid three-component millng force dynamometer developed in this university. The dynamometer features its monoblock body and a special damper. The basic dimensional parameters of the load-bearing elastic elements,the elongated octagonal rings, have been optimized, and the connection of the measuring electric bridge circuits is improved. Static and dynamic calibrations and actual cutting tests have confirmed that the main performan...
A simultaneous optimization of geometry and orbital exponents in ab initiocalculations is studied.The simplex method is employed in the optimization,and the STO-3G basis set is chosen.Full geometry optimizations with and wi-thout optimizing the STO exponents are carried out on hydrogen,methane,am-monia,water,hydrogen fluoride as well as their deprotonated species,The res-ults without exponent optimization are in excellent agreement with the dataavailable in literature.The resulting deprotonation energies ar...
