We show how to construct in a pure, lazy functional language Haskell a low-level, FORTH-like (stack based, postfix style) virtual machine, used as a target platform in our compilation course for computer science students. The implementation is clear, reasonably efficient, and easily extensible. Two models are presented: more “classical”, with a separate return stack, and an interpreter based on...

The demand on high stability and precision on the RF voltage for modern accelerators, as well as better diagnostics, maintenance and flexibility is driving the community to develop Digital Low Level RF systems (DLLRF) for both linear accelerators and synchrotrons. The state of the art in digital technologies applied to DLLRF systems is reviewed; different designs developed or in development at ...

OBJECTIVE Low vision rehabilitation is an emerging practice area for the field of occupational therapy. As a result there is a need to develop tools and training for fieldwork educators in this practice area. PARTICIPANTS Occupational therapists with no experience in low vision rehabilitation participated in the pilot of the tools and training developed. METHOD A literature review was compl...

Saliency regions attract more human’s attention than other regions in an image. Low- level and high-level features are utilized in saliency region detection. Low-level features contain primitive information such as color or texture while high-level features usually consider visual systems. Recently, some salient region detection methods have been proposed based on only low-level features or hig...
