Space , time and objects

It is standard procedure to distinguish different kinds of spatial representation, and the most basic distinction is between allocentric (or objective) and egocentric spatial representation. The idea is that egocentric spatial representation is how an organism represents its environment for purposes of perception and action. The directions involved in egocentric spatial representation are above...

Space - Time Coding for Aeronautical Telemetry : Part I — System Description

This paper described the design and implementation of a prototype transmitter and a prototype demodulator/decoder for space-time coded SOQPSK-TG for aeronautical telemetry. The design exercise showed that the space-time coding concept can be reduced to hardware. The laboratory bit error rate tests showed that the performance of the prototype demodulator in a 2-transmit/1-receive antenna configu...

Fields and Objects in Space, Time, and Space-time

The well-known distinction between field-based and object-based approaches to spatial information is generalised to arbitrary locational frameworks, including in particular space, time and space-time. We systematically explore the different ways in which these approaches can be combined, and address the relative merits of a fully four-dimensional approach as against a more conventional ‘three-p...
