This paper purpose a motion generator approach to translating human motion from video image sequences to computer animations in real-time. In the motion generator approach, a motion generator makes ...inferences on the current human motion and posture from the data obtained by processing the source video source, and then generates and sends a set of joint angles to the target human body model. Compared with the existing motion capture approach, our approach is more robust, and tolerant of broader environmental and postural conditions. Experiments on a prototype system show that an animated virtual human can walk, sit, and lie as the real human performs without special illuminations control.
The rice slender mutant (slr1-1) is caused by a single recessive mutation and results in a constitutive gibberellin (GA) response phenotype. The mutant elongates as if saturated with GAs. In this ...mutant, (1) elongation was unaffected by an inhibitor of GA biosynthesis, (2) GA-inducible α-amylase was produced by the aleurone layers without gibberellic acid application, and (3) endogenous GA content was lower than in the wild-type plant. These results indicate that the product of the SLR1 gene is an intermediate of the GA signal transduction pathway. SLR1 maps to OsGAI in rice and has significant homology with height-regulating genes, such as RHT-1Da in wheat, D8 in maize, and GAI and RGA in Arabidopsis. The GAI gene family is likely to encode transcriptional factors belonging to the GRAS gene superfamily. DNA sequence analysis revealed that the slr1-1 mutation is a single basepair deletion of the nuclear localization signal domain, resulting in a frameshift mutation that abolishes protein production. Furthermore, introduction of a 6-kb genomic DNA fragment containing the wild-type SLR1 gene into the slr1-1 mutant restored GA sensitivity to normal. These results indicate that the slr1-1 mutant is caused by a loss-of-function mutation of the SLR1 gene, which is an ortholog of GAI, RGA, RHT, and D8. We also succeeded in producing GA-insensitive dwarf rice by transforming wild-type rice with a modified SLR1 gene construct that has a 17-amino acid deletion affecting the DELLA region. Thus, we demonstrate opposite GA response phenotypes depending on the type of mutations in SLR1.
Zirconium-phosphate self-assembled films and their derivatives have been developed on aluminum alloy, AL1100. The characterizations of the self-assembled zirconium phosphate layers were executed by ...X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and atomic force microscopy. To examine the resistance of the films against corrosion, a salt-spray test has been executed. The test results have indicated that self-assembled zirconium-phosphate derivative films effectively protected aluminum substrates. In particular, the multi-layered zirconium-phosphate film fabricated by adsorbing 1,12-dodecyldiphosphonic acid has shown superior anti-corrosion properties to AL1100. The zirconium-phosphate self-assembled monolayers would be promising for surface finishing.
