In order to solve the fight problem of damaged airplane in war, based on linear elasticity, elastoplasticity and net section yield criterion, the calculation model for residual strength of plate with smooth circular hole is founded. Furthermore, the flexibility of calculation models using these three methods is analyzed through examples. All above can be basis for airplane battle damage assessment.
The necessity and actuality of spare part requirement prediction on aircraft battle damage assessment and repair were analysised. The calculation models, such as the quantity of the battle damage aircraft, the battle ...

The necessity and actuality of spare part requirement prediction on aircraft battle damage assessment and repair were analysised. The calculation models, such as the quantity of the battle damage aircraft, the battle damage number of aircraft component, the equipment of aircraft battle damage assessment and repair, were set up. They could provide the reference and basis for constituting the advance project of aircraft battle damage assessment and repair and for repair guarantee.

Objectives: The aim was to investigate the free fatty acid (FFA) metabolic profiles and to identify biomarkers that can be used to distinguish patients with breast cancer (BC) from benign (BE) patients or healthy controls. Design and methods: A total of 114 subjects were divided into the following three groups: BC patients, BE patients and controls. The FFA profiles in three groups were studied by gas chromatography-mass spectrometry coupled with multivariate statistical analysis. Results: Three saturated fatty acids (C14:0, C16:0 and C18:0) and three unsaturated fatty acids (C18:2. C18:3 and C20:5) in BC were significantly different than controls. Palmitic acid, stearic acid, linoleic acid and total FFA were identified as potential biomarkers distinguished BC from the other groups. Conclusion: The alterations of FFA could reflect underlying metabolic changes in BC patients, and this study has demonstrated that FFA biomarkers might be helpful for prevention and characterization of BC patients.

In this paper, an intelligent static traffic grooming scheme based on predatory search algorithm (PSA) and gaming is proposed in IP over WDM (Wavelength Division Multiplexing) optical Internet. Based on the layered graph, the proposed scheme tries to maximize the comprehensive user traffic request delay satisfaction degree and minimize the network relative cost, and then the optimal traffic grooming scheme is found through the transition between the local and the global search realized by adjusting the restriction level of search area. It is simulated over actual network topologies. Simulation results show that it is both feasible and effective with better performance than certain existing traffic grooming scheme.
