Construction for Ontology of Domain Terms and Tasks (ODT<sup>2</sup>)
Miyamoto, Junya,Kawabata, Ryo,Itoh, Kiyoshi The Korean Institute of Electrical Engineers 2013 The Journal of International Council on Electrical Vol.3 No.1
This papers proposes Diagram for Ontology of Domain Terms and Tasks (referred to as $DODT^2$) in order to visualize Ontology. $DODT^2$ is divided into two diagrams. The first diagram is Diagram for Ontology of Domain Tasks (referred to as DODTasks). DODTasks visualize Ontology of Domain Tasks represented in Case Grammar. A component of this diagram describes a term which corresponds to each case of Case Grammar. In addition, to respond to any of various situations, three notations for DODTasks are proposed: Conditional Branch, Parallel Execution, and Random Order. The second diagram is Diagram for Ontology of Domain Terms (referred to as DODTerms). DODTerms represents the super-/sub-relation of Domain Terms. Moreover, to assist Construction of Ontology, the author implemented $DODT^2$ Editor. It can edit $DODT^2$. $DODT^2$ Editor involves functions to help construction of Ontology.
CONSTRAINTS ON A-DECAYING COSMOLOGY FROM OBSERVATIONAL POINT OF VIEW

To constrain the values of the model parameters for the cosmological models involving the time-decaying $\Lambda$ term, we have computed sets of theoretical predictions for the N-m relation of galaxies as well as the CMB angular power spectrum: three types of variation, viz., ${\Lambda}{\propto} T^{-1},\;a^{-m}$, and $H^n$ are thereby assumed following Overduin & Cooperstock (1998), although we concentrate here on the discussion of the results obtained from the first type. Our results for the N-m relation indicate that the observed excess of the galaxy counts N in the faint region beyond the blue apparent magnitude 24 can be reasonably well accounted for with the value of ${\iota}$ in the range between 0.2 and 1. Furthermore, a comparison of our computational results of the CMB spectra with the observational data shows that the models with a mild degree of the $\Lambda$ term decay, viz., with the value of ${\iota}{\le}$0.4, are favorable. In this case, the age of our universe turns out to be larger than or equal to 14 Gyr, the lower limit inferred from some Uranium datings.
