Highly complex learning communities where diverse participants collaborate to achieve multiple aims through synergy have the potential to be highly creative and productive. However the diversity and multiple aims can also mean the advantages of a community share understand, trust and direction are difficult to achieve, resulting in few if any of the aims being realised. We review two case studi...

This position paper argues that more research is needed into identifying key abstractions and reference criteria for multi-purpose display systems. This would enable research in this area to go beyond the development of specific applications and move towards enabling infrastructures that could serve the needs of multiple applications.

A multi-purpose symbolic system which can describe all of the mouth shapes conveying various kinds of linguistic information in signing, speech dialogue, and speechreading is developed, taking account of the constraints of anatomical structure and neural control and the possibility of visual discrimination. In order to make the changes in the three-dimensional shape of lips, the changes are des...

This study established a list of criteria to select a first programming language. We used a literature study to create criteria for developing thinking and programming skills, student appropriate programming learning environments, new tendencies in programming, practical programming issues, affordability, training and resources, and general-purpose programming. An empirical study verified the v...

To address security of farm produce’s quality, using object-oriented technologies to build multi-purpose database, it meets the current and future data needs of a variety of operational systems. Further, base on WebGIS, to establish management and decision-making system for producing area, This system could be implement digital management for the entire agricultural park, and evaluate individua...
