OBJECTIVE To construct a life-sized eye model using the three-dimensional (3D) printing technology for fundus viewing study of the viewing system. METHODS We devised our schematic model eye based on Navarro's eye and redesigned some parameters because of the change of the corneal material and the implantation of intraocular lenses (IOLs). Optical performance of our schematic model eye was com...

Often, the geographic view of a network hides important connectivity information found in the network. In these cases a schematic diagram of the network data provides a representation in which connectivity relationships are highlighted. In this paper we explore issues relating to the development of information systems that not only support schematic representations of network data, but also all...

The article discusses various schematic diagrams of a reciprocating internal combustion engine (ICE) and shows their main disadvantages, in particular, low efficiency, which, depending on the type modern ICE, ranges from 0.25 to 0.5. To increase this indicator, search for more advanced ICE schemes continues. For purpose, new diagram free-piston (FPICE) is proposed, which power transferred by hy...

Abstract—In search-based graph drawing methods there are typically a number of parameters that control the search algorithm. These parameters do not affect the fitness function, but nevertheless have an impact on the final layout. One such search method is hill climbing, and, in the context of schematic layout, we explore how varying three parameters (grid spacing, the starting distance of allo...

The famous London Underground map shows the Thames and named metro stations with railway tracks as straight line segments. Strictly speaking, it is not a map that aims at a metrically accurate depiction of the network, but it is rather a diagram that accentuates the topological relations of Underground stations. Henry “Harry” C. Beck produced the first sketch for the famous diagram in 1931. His...
