The FCNTL module defines names for many of the operations you d pass to fcntl. For example, fcntl.fcntl(file.fileno(), FCNTL.F_GETFD) returns the close-on-exec flag for the given file descriptor.

Technical graphics in three dimensions are notoriously difficult to draw by hand. Luckily a number of mathematics programs are available to do the calculations and produce convincing illustrations. The Maple program has been used extensively to produce the diagrams in [1] and this book and this appendix shows some of the expressions used. Other mathematics programs also have graphics outputs and there are a number of computer programs that can translate from one language to another.

High Water Time For any given location, the time of day when high water springs occurs is roughly constant. Likewise the time of the local high water neaps is also roughly constant. Look at your local tide tables to see what these times are for your home port, and you then have a valuable planning tool. For instance, in the UK s Solent, high water springs occurs at approximately 12 midnight and 12 noon. High water neaps occur at approximately 6 a.m. and 6 p.m. If you look in your diary to check the phase of the Moon, you can get a reasonable idea of the time of high water, which can be useful if you don t have your tide tables to hand.

chose the RLAB reproduction as the best nearly 70% of the time, the CIELAB image about 30% of the time, and the XYZ image almost never This result showed that a color appearance transformation was indeed required for these viewing conditions and that the RLAB model outperformed CIELAB Kim et al (1993) examined the performance of eight color appearance transformations for printed images viewed under different viewing conditions Original prints were viewed under a CIE illuminant A simulator and reproductions calculated using the various appearance transformations were viewed under CIE illuminant D65 simulators at three different luminance levels A paired-comparison experiment was completed and an interval scale was derived using the law of comparative judgements A sucessiveGanzfeld haploscopic viewing technique (Fairchild, Pirrotta, and Kim 1994) was used with 30 observers.

The results showed that the Hunt, RLAB, CIELAB, and von Kries models performed similarly to one another and signi cantly better than the other models The Nayatani et al model performed worse than each of the above models Three models performed signi cantly worse and were not included in further experiments These included CIELUV, LABHNU2, and a proprietary model The Nayatani et al model performed poorly due to its prediction of the Helson Judd effect resulting in yellowish highlights and bluish shadows in the reproductions The Helson Judd effect cannot be observed for complex stimuli under these viewing conditions CIELUV and the others performed poorly due to their intrinsically awed chromatic adaptation transformations Pirrotta and Fairchild (1995) performed a similar experiment using simple stimuli on gray backgrounds rather than images.
