useful efficiency
2.On-board Processing(OBP) is an important direction in satellite communications, where on-board conversion from FDMA to TDM is very useful in raising channel efficiency and decreasing cost of earth stations.
3.It is very useful for technicians using these technology in synthetically to improve the efficiency of applying Pro/E,to boost development ability of series manufacture,to speed up the step of changing product,etc.
4.The results show:the groove depth is more important for diffraction efficiency than the duty cycle,which is useful for fabrication of the BSG.
5.Because of its simplicity and high efficiency, Cre/loxP site-specific recombination system has been widely used in gene deletion and function identification, gene site-specific integration, gene trapping and chromosome engineering. It has been used as a useful tool for DNA recombination in transgenic yeast, plants, insects and mammals.
6.Here we put forward some useful techniques and suggestions that we have practiced in our classes such as predication,skimming and scanning,reading according to the sense of group,up-down and down-up comprehension and the information gap by the board covering method in addition to learning new words,phrases,analysis of sentences,paragraphs and recitation of texts to raise the efficiency of teaching and learning.
7.(19.75%) THG efficiency with chirp pulse of(3.5 nm) bandwidth at average power of (1.5 GW/cm~2) was achieved at(25 mm) optimum distance between two triples in the experiment. It will be useful to solving the problem of the large bandwidth of the THG in the high power laser system.
8.Like F ̄+_2 color center,F ̄+_2 -type center has a strong dipole moment,3 sufficient Stokes shift to allow low self-absorption,yet high efficiency,and broad tunable emission ranges in 0.8-4.0 μm NIR,and made it a potentially useful laser medium,The energy level diagram of F ̄+_2-type center shows an excellent agreement with H ̄+_2model.
9.Abstract: In this paper,we propose an improved Lagrangian relaxation algorithm to solve job-shop scheduling problems.Besides the addition of augmented objective,we expand the search scope of near-optimal solutions and improve the computational efficiency greatly by restricting the solution scope of sub-problems and modifying the search method of dual problem.At the same time,we develop a genetic algorithm combining with the LR(Lagrangian relaxation)method.Using the numerous useful solutions we get in the Lagrangian relaxation as the original genes,we can improve the solution further.Test results show that these methods achieve satisfied outcome for job-shop problems.They can also be applyed to other programming problems with constraints.
