Contrastive Characters of Spatial Composition Process between Architecturally Trained and Untrained Students

Inductive logic programming was applied to the analysis of spatial composition processes using an architectural space montage technique. The complexly structured data of the spatial composition processes that consist of many objects, their relationships, and their attributes were modeled with first-order logic. One architectural space montage technique experiment was conducted on 14 architecturally trained students and on 14 untrained students. These experimental cases were analyzed by Progol, which is one ILP system. 513 rules for the trained students and 458 for the untrained students were found. By comparing these rules, we found contrastive characteristics between the two groups from four points of view: (1) extension method of chain of miniatures, (2) relationship as basic unit of composition, (3) type of miniature, and (4) multiplicity of rules

Survey of Period Variations of Superhumps in SU UMa-Type Dwarf Novae. VIII: The Eighth Year (2015-2016)

Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016 season and characterized these objects. The data have improved the distribution of orbital periods, the relation between the orbital period and the variation of superhumps, the relation between period variations and the rebrightening type in WZ Sge-type objects. Coupled with new measurements of mass ratios using growing stages of superhumps, we now have a clearer and statistically greatly improved evolutionary path near the terminal stage of evolution of cataclysmic variables. Three objects (V452 Cas, KK Tel, ASASSN-15cl) appear to have slowly growing superhumps, which is proposed to reflect the slow growth of the 3:1 resonance near the stability border. ASASSN-15sl, ASASSN-15ux, SDSS J074859.55+312512.6 and CRTS J200331.3-284941 are newly identified eclipsing SU UMa-type (or WZ Sge-type) dwarf novae. ASASSN-15cy has a short (~0.050 d) superhump period and appears to belong to EI Psc-type objects with compact secondaries having an evolved core. ASASSN-15gn, ASASSN-15hn, ASASSN-15kh and ASASSN-16bu are candidate period bouncers with superhump periods longer than 0.06 d. We have newly obtained superhump periods for 79 objects and 13 orbital periods, including periods from early superhumps. In order that the future observations will be more astrophysically beneficial and rewarding to observers, we propose guidelines how to organize observations of various superoutbursts.Comment: 123 pages, 162 figures, 119 tables, accepted for publication in PASJ (including supplementary information

Design of Hanshin Electric Railway Naruo Station with Plank Sheets

This paper reports a Japanese railway station’s design that consists of minimal architectural materials and a structural experiment with plank sheets as an element of shell structure. The station’s space is created by unifying walls and ceilings with plank sheets that do not require any support. Stairs, escalators, elevators, and signs are clearly visible as symbolic components for the passengers
