    Calcium peroxide as a seed coating material for padi rice (1987)

    Notizen: Summary Measurement of oxygen uptake by germinating rice seed (Oryza sativa L) suggests that oxygen requirement is independent of temperature of incubation. However, the rate of oxygen consumption is dependent upon incubation temperature and, after an initial lag phase, is exponential with time. Although rice seed can germinate and grow at low oxygen concentrations, germination is poor and seedlings exhibit low vigour. An oxidized zone may be observed around the seed when sown in an anoxic environment but coated with a layer of calcium peroxide. The seed germinates readily and develops normally when a sufficient level of calcium peroxide is used.

    Notizen: Summary Glasshouse trials indicate the optimum coating for rice seed as 35% (w/w) on seed weight of 60% calcium peroxide. Coatings in excess of this show no improvement and a 20% (w/w) coating gives comparable results to pregerminated seed. As compared with untreated or pregerminated seeds an optimum seed coating of calcium peroxide increases the number of seedlings emerging through the water layer when rice seed is sown on the soil surface of waterlogged soil or at a depth of 1 cm below the soil surface. The coating is applicable to a wide range of rice growing temperatures and not influenced by soil type.

    Notizen: Summary Redox and chemical analysis techniques have measured the decomposition of calcium peroxide-coated rice seed (Oryza sativa L.) under flooded padi conditions. Decomposition rates, even in acid soils at high temperatures, are show enough to extend over the oxygen demand period of the germinating seed. Rice seeds coated with calcium peroxide are relatively stable and viable over a wide range of storage conditions. Magnesium peroxide coatings decomposition at approximately half the rate of calcium peroxide coatings. Differences in alkalinity, cation and oxygen release rate make magnesium peroxide a useful alternative system to calcium peroxide.

    A fault injection experiment using the AIRLAB Diagnostic Emulation Facility (1988)
    In:  CASI
    Details
    Publikationsdatum: 2019-06-28
    Beschreibung: The preparation for, conduct of, and results of a simulation based fault injection experiment conducted using the AIRLAB Diagnostic Emulation facilities is described. An objective of this experiment was to determine the effectiveness of the diagnostic self-test sequences used to uncover latent faults in a logic network providing the key fault tolerance features for a flight control computer. Another objective was to develop methods, tools, and techniques for conducting the experiment. More than 1600 faults were injected into a logic gate level model of the Data Communicator/Interstage (C/I). For each fault injected, diagnostic self-test sequences consisting of over 300 test vectors were supplied to the C/I model as inputs. For each test vector within a test sequence, the outputs from the C/I model were compared to the outputs of a fault free C/I. If the outputs differed, the fault was considered detectable for the given test vector. These results were then analyzed to determine the effectiveness of some test sequences. The results established coverage of selt-test diagnostics, identified areas in the C/I logic where the tests did not locate faults, and suggest fault latency reduction opportunities.

    A simulation-based fault injection experiment to evaluate self-test diagnostics for a fault-tolerant computer (1988)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-13
    Beschreibung: The design and results of a fault injection experiment conducted in the Airlab facility at NASA-Langley using a logic network simulator are described. An attempt was made to determine the effectiveness of the diagnostic self-test sequences used to detect failures in the communicator/interstage (C/I) of a fault-tolerant processor (FTP). Identification of the undetected faults in the C/I Status Register logic resulted in changes in the diagnostic test sequences implemented for the FTP.
