Motion analysis is a common clinical assessment and research tool that uses a camera system or motion sensors and force plates to collect kinematic and kinetic information of a subject performing an activity of interest. The use of force plates can be challenging and sometimes even impossible. Over the past decade, several computational methods have been(More)
The subject matter of this note was originally contained in a paper presented at the conference quoted in reference [Dau]. As we were preparing the final manuscript for the conferenc e proceedings, we realized that this subject was somewhat out of orde r within the context of that particular paper, reason why it is bein g left out of the final version.

In this note we describe conventions for string handling, and in particular for efficient string length encoding. These conventions are based on the (C-language) zero--terminator convention, and assume that the size of the area containing the string is known. They do not require any special provisions on the part of the language implementation. The(More)
1. Terminology We make a distinction between virtual memory and address mapping. Virtual memory is concerned with the mapping of a potentially large address space to a small (primary) memory. Address mapping (sometimes called memory management) is concerned with the mapping of a relatively small logical address space (e.g., limited to a 16 bit address) to a(More)
