Abstract:
When characters are allocated to a keyboard, a plurality of consonants are divided into a plurality of groups according to pronunciation position in the oral cavity, and the groups are allocated to corresponding columns on the keyboard of (3) rows and (10) columns. A plurality of vowels are allocated to the corresponding columns according to the pronunciation position in the oral cavity. In this instance, the consonants and the vowels of which the pronunciation position are near the lips are allocated to the middle area of the area of (3) rows and (10) columns, and the consonants and the vowels of which the pronunciation position are near the vocal chords are allocated to the outer part of the area of (3) rows and (10) columns. The consonants and the vowels are allocated to the corresponding rows of the area of (3) rows and (10) columns according to usage frequency.

Abstract:
An apparatus for wavelength assignment in wavelength multiplexing optical ring networks includes: a node section receiving a connection setup request, the node section comprising a plurality of nodes; and a wavelength assignment controller connected to the node section for, when the connection setup request occurs, determining paths available between the nodes using sparse wavelength conversion and limited wavelength conversion, calculating the total number of gaps for each node available, and assigning wavelengths to a path having the smallest total number of gaps. The present invention assigns wavelengths in consideration of both sparse wavelength conversion and limited wavelength conversion to minimize the call-blocking probability, and uses the wavelength in adjacent partitions to calculate the number of gaps for each wavelength and the total number of gaps.
