SC and pass transistor combined circuits

The pass-transistor structure provides a powerful tool for the implementation of binary and multiple-valued logic (MVL). Circuit realisation of any general MVL function using literals, MAX and MIN is easy. However, the resulting circuits have certain limitations. A combination of pass transistors (PT) with switched-capacitor (SC) circuits is shown to provide useful improvements.<>

Learning LOGO: effects on learning BASIC and statistics

Abstract Two experiments were conducted to examine the effects of a period of training in the use of the turtle graphics aspects of LOGO on both attitudes towards computers and the learning of BASIC and statistics. A group of 15 subjects spent 10 hours learning LOGO . Their performance on subsequent learning of BASIC was significantly better than that of a control group, but no differences were found in attitudes towards computers or in the learning of statistics.     

Reliable real-time robot operation employing intelligent forward recovery

Modern computer-controlled robots typically fail at their tasks whenever they encounter an error, no matter how minor. The physical environment of a typical assembly robot is too unstructured to benefit from conventional software approaches to reliability. We present an approach which interfaces the real-time operation of the robot with an intelligent subsystem that performs error analysis and forward recovery if a failure occurs. Our approach involves a special representation of the robot's program that efficiently tracks the robot's operation in real time and is easy to modify to include automatically generated recovery procedures.
