This paper deals with the use of Dynamic Geometry Software for teaching. We will focus on the software package WinCAG. This has been especially designed for teaching and learning (Descriptive) Geometry. It aids the visual understanding of essential aspects and interrelations for different phenomena. Modifying the viewpoint the drawings get into motion, which clarifies the shapes of the projecte...

UNLABELLED The OLINDA/EXM version 1.0 personal computer code was created as a replacement for the widely used MIRDOSE3.1 code. This paper documents the basic function of the code and how it is similar to and different from the MIRDOSE software. METHODS After creation of the code and alpha- and beta-testing phases, a premarket notification submission (510(k)) was filed with the Food and Drug A...

This papers explores some system design issues regarding the structuring and information flow of complex distributed virtual environments (VEs) containing one or more users and dialogue agents. A specification technique is proposed for modelling such systems. We define a specification technique as a suite of interrelated specification languages. It is argued that specification techniques should...

An automatic Botnet detection and notification system is developed by National Center for High-Performance Computing (NCHC) in Taiwan to efficiently inform users of malware infections on their computers. Due to the involvement with manual work in current notification flow, the notification time may last for 48 to 60 hours. By the aid of our notification system, the infected bot can be notified ...

Supporting project awareness in the context of large-scale software development is difficult. One key problem is identifying appropriate abstractions and techniques for the insertion of project awareness mechanisms into a software development environment with minimal impact. An additional problem is scaling project awareness mechanisms to handle the demands of large-scale software development p...

BACKGROUND In Australia, rural and remote communities have high rates of diabetes-related death and hospitalisation. General practitioners (GPs) play a major role in diabetes detection and management. Education of GPs could optimise diabetes management and improve patient outcomes at a population level. The study aimed to describe the uptake of a continuing medical education intervention for ru...

In hierarchical task analysis, designers study and decompose the tasks users perform while interacting with a system. Overlooking task analysis can have serious consequences on the design outcome. By making tasks clear to the designers, we can leverage an in-depth understanding of a usage scenario. Resulting from task analysis is a task model that explicitly enumerates the low-level tasks and a...

Publish/subscribe infrastructures, specifically event notification services, are used as the basic communication and integration framework in many application domains. The majority of these services, however, provide poor or no extension mechanisms as well as insufficient configuration capabilities. As a consequence, different event notification servers have been developed previously to support...
