crossover
At each iterate, by reduplication, crossover and mutation, a finite set of points can be used.
      
For the genetics algorithm, chromosome coding, fitness function, parameters selection, and the basic genetics operation including selection, crossover and aberrance, are described.
      
Eight young, healthy male volunteers were exposed to two 24 h periods of continuous wakefulness during the crossover experiment.
      
Numerical investigation of aerodynamic performance influenced by circumferentially pre-swirling coming flow on the crossover and
      
Numerical investigation is implemented on aerodynamic performance inside the crossover and de-swirling cascade of a multistage centrifugal compressor.
      
The results indicate that flow separation occurs inside the crossover, and the separation area may be changed with different circumferentially pre-swirling coming flow.
      
Decreased pre-swirling intensity of the coming flow may effectively restrain the flow separation and make the outflow from the crossover more uniform, which helps to improve the aerodynamic performance of the successive de-swirling cascade.
      
The regularities of motion of a point on the plane (in the space) of adjustable controller parameters at variations of the phase margin under a fixed crossover frequency were analyzed.
      
To investigate the function of this gene in MSR-1, a fur mutant was generated by double crossover with a kanamycin cassette inserted into its coding region.
      
It is shown that the introduction of 20-25 mol % PbF2 leads to a crossover from the protonic conductivity to the unipolar fluorine ionic conductivity ().
      
An increase in the electrical conductivity and a decrease in the activation energy for electrical conduction are interpreted in the framework of a crossover of the migration mechanism.
      
An analysis of the results obtained shows that the mechanism of relaxation process of the low-temperature stabilization undergoes a crossover in the vicinity of the glass transition temperature.
      
Crossover relations for "simple" systems in the critical region
      
This relation is used to derive crossover relations which describe the thermophysical properties of the liquid and vapor phases in the critical region.
      
The errors in determining the crossover position and the beam radius in the crossover do not exceed 15%, and the error in estimating the emittance depends on the relationship between the emittance and space charge forces.
      
Coincidence summing in γ-ray spectra and determination of the intensity of weak crossover γ transitions
      
The intensities of peaks formed in γ-ray spectra by summing the pulses due to coincident cascade γ transitions in radioactive nuclides are used to determine the intensities of weak crossover γ-radiative transitions.
      
A procedure for measuring γ-ray spectra and calculating the intensities of crossover γ transitions is proposed.
      
It is shown that the proposed technique can be used to observe crossover γ transitions with an intensity as high as ~5×10-5 per decay.
      
The upper limits on the intensities of crossover γ transitions in decays of 208Tl and 207Bi nuclei have been determined for the first time.
