Documents that express an opinion abound, especially in the so-called web 2.0 era of social media and social networking. Jae-Young Chang of the Department of Computer Engineering at Hansung University, in Seoul, South Korea, suggests that there is a need to find ways to summarize their contents for a wide range of applications.

High-quality extended reality in easy-to-use and inexpensive devices

Leave a Comment / Business /

Augmented reality (AR), virtual reality (VR), and mixed reality (MR) technology open new possibilities across many fields. However, high-quality extended reality (XR) applications are computationally heavy in terms of computer graphics, which means that they do not run smoothly on inexpensive and easy-to-use XR devices such as VR/AR headsets and smartphones, because their GPU computing

Discovery of accurate and far more efficient algorithm for point set registration problems

Leave a Comment / Business /

A point set registration problem is a task using two shapes, each consisting of a set of points, to estimate the relationship of individual points between the two shapes. Here, a “shape” is like a human body or face, which is similar to another body or face but exhibits morphological diversity. Taking the face as

WHO launch eEML

Leave a Comment / Health Articles /

The World Health Organization has launched a new easy-to-access, digital version of its Model list of Essential Medicines (EML). The move will revolutionize the way this core WHO reference tool is used. More than 150 countries currently use the WHO list to work out which medicines best meet their national health contexts and priorities, so they
