The application of COS/MOS integrated circuits in the construction of a three-valued positional control system is presented. A unit-distance ternary code and the design of a ternary encoder are given. A ternary code converter able to translate this unit-distance code to the signed ternary code is described. A ternary threshold level detector is required to convert a noisy, slowly-changing, anal...

Computer Go offers researchers a new challenge and opens up a very wide scope of possibilities for artificial intelligence. In a computer Go program, the most important element is a positional judgment system. Following the methods of human Go experts, we designed and implemented a new model of positional judgment for computer Go. This model was employed successfully in a computer Go program, J...

Compartmented Bienzyme Biocatalysts Biomimetic mineralization and slow seed-induced nucleation strategy enables the synthesis of compartmented bienzyme system based on core-shell [email protected] in aqueous solution. can be accurately localized into shell core with uniform distribution. The optimization pore structure positional assembly provides a guidance for preparing efficient multi-enzyme...

The concept of configuration of groups which is defined in terms of finite partitions and finite strings of elements of the group is presented by Rosenblatt and Willis. To each set of configurations, a finite system of equations known as configuration equations, is associated. Rosenblatt and Willis proved that a discrete group G is amenable if and only if every possible instance of its configur...

What a study of the historical development of mathematical concepts can offer teaching is still being debated. This study examines use of a combination of the historical development of number systems and modelling, with concrete materials as a way of deepening students’ understanding of positional notation. It looks at place value in different number bases as a way of enhancing students’ unders...
