Two hazards commonly associated with manual memory management are allocating a block of memory without ever freeing it (memory leak) and attempting to access a block of memory which has already been freed (dangling pointer access). Tofte and Talpin described a “region type” system, in which data in the store is associated with a named region. The expression (e at ⇢) allocates store space for th...

Introduction We can learn a lot by studying the development of object perception and recognition. For example, creating a developmental timeline of perceptual abilities can help to show which tasks are most easily learned and performed. In turn, this ordering can be used to break a complex perception task into a series of simpler components. Studies often reveal impressive perceptual skills in ...

This white paper supports the goal of establishing Computer Vision as a coherent intellectual discipline by suggesting a specific agenda for the unification of many low-level vision principles, algorithms, and data structures. Our goal is to identify a set of highly related low-level vision problems, define their common structure, and establish a coherent intellectual discipline around the shar...

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...

Anthropogenic emission of platinum group elements (PGEs) from the abrasion of automotive catalytic converters into the environment has significantly increased. Dust emitted from the catalyst is causing pollution problems of these metals in the future. However, the concentration level of these PGEs is still very low in the nature. The choice of which determination method to use depends on the le...
