Large is Beautiful – Progress of HelioFocus 500 m2 Dish

A NEW 500 m2 PARABOLOIDAL DISH SOLAR CONCENTRATOR

The Australian National University (ANU) has worked for many years on paraboloidal dish solar concentrators and demonstrated a 400m2 system in 1994. The commercialization of this technology has involved a re-design of the Big Dish concept for mass production. The new design is a 494 m2 concentrator with 13.4 m focal length and altitude-azimuth tracking. It uses 380 identical spherical 1.17m × 1...

What is beautiful is usable

An experiment was conducted to test the relationships between users' perceptions of a computerized system's beauty and usability. The experiment used a computerized application as a surrogate for an Automated Teller Machine (ATM). Perceptions were elicited before and after the participants used the system. Pre-experimental measures indicate strong correlations between system's perceived aesthet...

Is DISH painful?

Framelets—small is beautiful

The contribution introduces the notion of framelets. They are essentially small frameworks. Thus framelets can be easily understood and modified. As framelets are not aimed at complex application domains, they can also be assembled without the problems associated with the combination of large frameworks. Our first experiences with framelets demonstrate that these architectural building blocks a...
