Tabular forms are commonly used in software. Those tabular forms are represented as rectangular dissections. In rectangular dissections, ruled line oriented operations such as cell merge, line and column operations are often used. With respect to ruled line oriented operations, 8k-ary grid graphs have been introduced as models of rectangular dissections that provide fast algorithms. This paper surveys octal and hexa-decimal grid graph models of rectangular dissections. First, octal grids, called octgrids, for single layer rectangular dissections and related algorithms are introduced. Next, hexa-decimal grid graphs for multiple layer rectangular dissections, called hexadeci-grids, and related algorithms are introduced. Furthermore, tetraicosa-grid graphs for rectangular solid dissections for CG applications, called tetraicosa-grids and related algorithms are introduced. © 2014 Springer-Verlag Berlin Heidelberg.

In order to decipher the origin and tectonothermal history of the Kuncha nappe, we undertook a geological investigation in the Taplejung window in eastern Nepal, and carried out multichronological analyses of zircon, apatite, and mica of the Kuncha Formation and Taplejung granites. Three granite bodies that intrude into the Kuncha Formation show fission-track (FT) ages of 6.2 to 4.8Ma for zircon and 2.9 to 2.1Ma for apatite, although the granites yielded zircon U-Pb ages of 1852±24Ma and 1877±21Ma, and muscovite 40Ar-39Ar ages of ca 1650Ma. The U-Pb intercept age of detrital zircons from the Kuncha schist is 1888±16Ma, and this age represents a probable depositional age of the lower part of the Kuncha Formation. The FT ages of zircon and apatite from the same schist are found to be 5.4 and 2.5Ma, respectively. No zircon younger than 1.6Ga was identified from any of these samples. It means that the Kuncha nappe has never undergone thermal events after 1.6Ga until the Himalayan orogeny in Miocene. The Kuncha Formation and overlying Kali Gandaki Supergroup as well as the Taplejung granites can be correlated with the Coronation Supergroup and the Hepburn intrusives in the Wopmay orogen, northwest Canada. They are interpreted to be deposits in the basins of continental rift system and subsequent passive-margin settings. All the FT age data of zircon and apatite provide evidence that both the Kuncha nappe and overlying Crystalline nappe seem to have cooled laterally from the nappe front to the north. The FT ages from the front to central part of the nappe in Taplejung suggest that isotherm of 240°C, closure temperature of zircon FT, retreated toward north at about 10mm/y during the middle to late Miocene and Pliocene. © 2013 Wiley Publishing Asia Pty Ltd.

A multichronological study of the weakly metamorphosed Early Miocene fluvial Dumri Formation and the overlying Kuncha and Lesser Himalayan Crystalline nappes has helped to clarify the timing and heat source of the metamorphism, as well as the history of emplacement and cooling of the nappes. U-Pb ages of detrital zircons from the Dumri Formation show peaks at ca 1Ga and 500-600Ma, and fission-track dating indicates a thermal imprint on the formation at 11-10Ma. In the Naudanda Quartzite, overlying the Kuncha Formation, reset fission-track detrital zircon ages are 9.5Ma, but the U-Pb ages are older than 1.7Ga. The differences in the U-Pb ages for detrital zircons from the Dumri and Kuncha Formations indicate that the Kuncha nappe was never exposed at the surface during the Early Miocene when the Dumri Formation was deposited. Two-mica garnet schists of the Main Central Thrust (MCT) zone have fission-track detrital zircon ages of 7.8Ma and 40Ar-39Ar muscovite ages of 19Ma, though the zircons have U-Pb ages older than 600Ma. Our interpretation is that the heat for the Dumri Formation metamorphism came from the overlying nappes. The timing of the thermal imprint on the Dumri Formation indicates that the metamorphic nappe reached its present position before ca 10Ma. The Parajul Khola granite in the frontal zone of the Kuncha nappe yields U-Pb zircon ages of 1.89Ga, and it underwent an Early Miocene thermal event, cooling below 240°C at 14.7Ma and below 100°C at 10.3Ma. These thermochronological data suggest that the frontal part of the Kuncha nappe was exposed at the surface around 15-14Ma and cooled immediately, but inner parts of the nappe were still hot during its emplacement. © 2013 Wiley Publishing Asia Pty Ltd.

We deal with a formalization of financial statements. In order to formalize financial statements, we have to specify the spatial order of items, and specify calculation methods. In this paper, we construct a context sensitive graph grammar to specify the order of items of financial statement. Furthermore we also append attribute rules to the context-sensitive graph grammar to specify calculation methods © 2011 IEEE.

We deal with a formalization of financial statements which is a type of business documents. In order to formalize financial statements, we have to specify the order and number of items, and specify calculation methods. In this paper, we construct a context-sensitive graph grammar to specify the order of items of financial statement with heterogeneous parts. We also show examples of derivation. © 2015 IEEE.
