12. This requires a reasonably steady PSF because images of different stars are taken on different days.

13. Based on Fourier optical theory, PSF(Point Spread Function)and OTF(Optical Transfer Function)are introduced. Then the mechanism why digital image is focused in optics imaging system is also analyzed.

14. Due to the increased cost of polyester raw materials, DAK Americas will increase prices for all Polyester Staple Fiber (PSF) products.

15. A new method is proposed for estimating the PSF(point spread function) values of turbulence from turbulence degraded images.

16. The definition and properties of commutative weakly left PSF monoids are introduced, and furthermore a kind of special monoid which all weakly flat acts are flat are discussed.

17. The opportunity and challenge of pelletizing shaft furnace( PSF ) at present in China were firstly analyzed.

18. BACKGROUND: Acute suppurative thyroiditis (AST) is very rare. Pyriform sinus fistula (PSF) is implied as a cause of AST.

19. The point-spread function (PSF) characterizes the resolution of the image(), which is a function of the receiving array length and the ambient bandwidth.

20. Based on physical optics theorem, point spread function (PSF) is calculated.

21. By means of two - step dry mixing - loosening technique, the problem of even dispersing of PSF was solved.

22. Summary of Background Data. A common treatment for spasticity in children with cerebral palsy is ITB. This population also has a high incidence of severe spinal deformities requiring PSF.

23. Fluorescence power transfer function, three dimensional point spread function (3D PSF) and three dimensional optical transfer function (3D OTF) for the various fluorescent wavelength are calculated.

24. The increase of PEG concentration changed the phase balance in the PSF/PEG casting membrane liquid system which became an unstable one, and speeded up the phase separate.

25. Synthesis and characterization of a series of Polysulfone ( PSF ) - Polyesters ( PEs ) block copolymers were undertaken.

26. Objective. To report the technical considerations and complications associated with ITB in patients undergoing PSF.

27. A novel friction material reinforced with polysulfonainide fiber ( PSF ) was developed.

28. Selected swelling agent was applied to dyeing sequence of polysulfonamide fabric ( PSF ).

28. try its best to collect and build good sentences.

29. The impact strength of their composites increases obviously and, being toughened with PSF, by a factor of 90 %.

30. Depending upon locality, these vary from about 10 to 50 psf.

31. The algorithm restores the image and the point - spread function ( PSF ) simultaneously.

32. A multiplicative iterative blind image deconvolution algorithm was proposed, in which both estimated image and Point Spread Function (PSF) were assumed to follow Markov Random Field (MRF) models.

33. Electrospun PSF nanofibrous membranes were prepared to toughen TGDDM epoxy resin.

34. The basement membranes for ultrafiltration process are prepared by using L-S phase inversion method with PSF and PES as membrane materials, water as internal coagulant agent.

35. A new way to discrete the continuous PSF also deduced, which has the higher precision.

36. A model was set up to determine the termination of the condensation of PSF resin.

37. The most complete measures of image quality for an optical system were its point spread function (PSF) and its optical transfer function (OTF).

38. A hollow fiber ultrafiltration membrane was prepared by using polyvinyl chloride (PVC) and polysulfone (PSF) blends and the dry wet spinning technology.

39. MTF can be deduced by PSF and the filter used in image reconstruction can be made thereby, so the accuracy of PSF directly affects the performance of reconstructed image.
