We propose a new hypermedia data model, called CHM for Contained HyperMedia. Our model is based on set-oriented data structuring, with a strong emphasis on automatic maintenance of link integrity. In this paper, the CHM model is presented in detail: both data structuring, navigational facilities and authoring support are presented. We will also explain how we have integrated support for the CHM...

A n advantage of believing that observations are the foundation of scientific method is that the conditions in which they are made can be stated and then produced. The simplicity of this has its appeal for the psychoanalyst: an analytic situation is presumed to exist and interpretations of the observations made in that situation are then reported. It is possible to believe that the analysis has...

This paper argues that elliptical VPs do not necessarily present cases of VP ellipsis. Certain relative clauses that contain elliptical VPs are analysed as instances of transitive verb phrase ellipsis. A storing account of ellipsis resolution is given. Resolution of TVP ellipsis is achieved by resolving a binary relation that derives from an antecedent TVP. This avoids the problem of antecedent...

The possibilities for tunable electrically small antennas are explored and analyzed. Although experimental determinations were made of impedance characteristics from 30 to 220 MHz, the objective was to study the possibility of tuning and bandwidth control for antennas in the range 30 to 100 MHz. A considerable part of the discussion is devoted to acceptable circidt representations or models for...

High-level programming languages and bytecode-based virtual execution environments have become popular in software development. Bytecode-based runtimes extend embedded system by techniques to improve safety, help portability and interoperability. The ECMA/ISO Common Language Infrastructure (CLI) specifies a bytecodebased execution environment (Common Language Runtime) and a comprehensive class ...

Lewin has proved that if S is a ring and R a subring of finite index in S, then R contains an ideal of S which is also of finite index; and Feigelstock has recently shown that other classes of subrings must contain ideals belonging to the same class. We provide some extensions of these results, and apply them to prime rings. In the final section, we investigate finiteness of rings having only f...
