Abstract: Robust header compression (ROHC) [1] is recently developed to be used in wireless last hop links of global Internet. It is built around an extensible core framework that can be tailored to compress new protocol stacks by adding additional ROHC profiles. The role of formal notation

, that the some of the same cognitive resources involved in representing spatial relations and proximities are also involved in representing symbolic notations. In short, formal notations are used as a kind of diagram. We examine selfgenerated productions in the domains of handwritten arithmetic expressions

This article explores a dual approach to real-time software development. Models are written in UML, as this is expected to be relatively easy and economic. Then models are automatically translated into a formal notation that supports the verification of properties such as safety, utility, liveness

(finite, small) models of the specifications. Another possibility is to build a running prototype from those specifications. In this paper we show how to obtain executable prototypes from formal specifications written in an object oriented notation by translating them into logic programs. This has a

Abstract: Active Graphing has been proposed as a spreadsheet-based pedagogic approach to support young children’s construction of meaning for graphs, particularly as a tool for interpreting experiments. This paper discusses aspects of a detailed study, illustrating how Active Graphing emerges as a facilitator of the children’s passage from a vague realisation of relationships to the articulation of rules and finally the construction of formulae.

by the program and its specification. Since it requires a minimal mathematical background and reflects the way programmers reason about the correctness of a program informally, it can be taught and practiced effectively. However, there is no formal notation supporting the functional program verification

Close to 30 percent of all patents are chemical patents, of which roughly 10 percent claim IP rights over novel chemical structures using the Markush notation[1-5]. An example of an approved patent with claims on a series of 4-anilino-3-quinolinecarbonitriles-based chemical structures for the
