Therefore popular points and difficult questions of development of simulation software focus now on integrated modeling and simulation environment, sharable software framework, distributed virtual environment, synthesis simulation system and multi-agent system and so on.
And, on the basis of the above research, through further investigation of SCORM RTE API, SCORM RTE Data Model Elements, and communication mechanism between SCO and LMS, compounding with popular webpage editor,the research realized a tool of Dreamweaver plug-in based on SCORM--QuestionsBuilder.
而且,在以上研究的基础上,通过深入探索SCORM RTE API、SCORM RTE Data Model Elements以及SCO(可共享内容对象)和LMS之间的通信机制,在具有广泛用户基础的成熟的网页编辑工具上进行再次开发和标准化封装,实现了标准化网络课件开发系统的典型组成模块——基于SCORM的标准化在线试题制作插件QuestionsBuilder。
The institute of ADL(Advanced Distributed Learning) proposes for the perspective of resource a "Shareable Content Object Reference Model"(known as SCORM), aiming at solving the problems of the shareability of the learning content, interoperability, coordination in a larger scope, and intelligent guide of the distributed learning.
This also leads to a rethinking of ideology and power: as being to do with, not ideas, but the practical shaping (or not) - in moments when in practical communication with others - of collective, sharable forms of life.
In the paper, shared image, including its basic idea, characteristics, applica- tions, and related problems, is discussed, The methods, an example and some viewpoints for inplementing the shared image using VAX computer are presented.
Middeldorp and Toyama showed that it is sufficient to impose the constructor discipline to term rewriting systems for obtaining the modularity of completeness and a constructor system may be decomposed into parts which possibly share function symbols and rewrite rules in order to infer completeness.This paper generalizes their conclusion.When constructor system refer to some function symbols defined in other systems,modularity of completeness are preserved.This conclusion is useful for algebraic specificati...
Synchronous token is a new netwrok access control mode. By introducing synchronous clock and token chain,network nodes can share a common data link, and their access control circuits can be as simple as only using several D F/Fs.It has some advantage against conventional token mode.When transmission throughput and speed are not high,it works better.In the article,an application example is also discussed.
