A control system for Hall B at the Thomas Jefferson National Accelerator Facility is being developed within the framework of the Experimental Physics and Industrial Control System (EPICS). The Hall B equipment currently under EPICS control includes numerous beam line devices, high voltage power supplies, detector gas systems, and safety systems. The status of the control system is described.

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well-controlled tactile signals in order to conveniently demonstrate four different tactile ill...

In July 2000 I spent 3 weeks in Haiti on a medical student elective. Eager to work in a new country and experience a new culture, I’d read about Haitian culture and history. This was my first exposure to medicine outside of North America. People warned me: “Haiti? Be careful! You can’t trust anyone there! They’re so poor, they’ll take anything they can get their hands on!” I was confident commo...

The problems of reactive power compensation and improving the quality electrical energy in supply systems industrial enterprises are inseparable. Their relevance is due to widespread use electric receivers that consume distort network, as well implementation new technologies, equipment into production make increased demands on consumed. An important characteristic rationed by GOST 32144–2013 no...

Mass casualty events and disasters, both natural and human-generated, occur frequently around the world and can generate scores of injured or ill victims in need of resources. Of the available medical supplies, oxygen remains the critical consumable resource in disaster management. Strategic management of oxygen supplies in disaster scenarios remains a priority. Hospitals have large supplies of...

Historically, the locations of cities mainly depend on the available water source and the urban river not only supplies the fresh water to city but also receives its wastewaters. To analyze the influences of urban zone on its receiving water river, the Jialu River in Henan Province, China, a typical urban river was chosen. Water and sediment samples were collected along the river in 2007 to ana...

Array detector-based instruments are now fundamental to measurements of ozone and other atmospheric trace gases from space in the ultraviolet, visible, and infrared. The present generation of such instruments suffers, to a greater or lesser degree, from undersampling of the spectra, leading to difficulties in the analysis of atmospheric radiances. We provide extended analysis of the undersampli...
