This paper reports on a study into the aggregate power quality from multiple grid connected inverters. Measurements are presented for individual single-phase inverters generating into the low voltage network under a range of operational conditions, and for groups of similar converters connected at the same point on the network. Some results from the(More)
To accelerate both protons and heavy ions, the AGS (Alternating Gradient Synchrotron) booster requires a broadband (multi-octave) beam position monitoring system with a dynamic range spanning several orders of magnitude (2*10/sup 10/ to 1.5*10/sup 13/ particles per pulse). System requirements include the ability to acquire single-turn trajectory and average(More)
Background: Double contrast barium enema (DCBE) is the examination carried out most frequently for investigation of patients with large bowel symptoms. The aim of this study was to compare the sensitivity of DCBE and colonoscopy for the detection of colorectal cancer and neoplastic polyps ?1 cm. Methods: All patients undergoing DCBE (1389) or colonoscopy(More)
This chip, fabricated in a 0.25/spl mu/m 5M1P CMOS process with 3.7M transistors, implements a fully-compliant IEEE 802.11a PHY modem. The IEEE 802.11a standard provides for wireless local area networks (WLANs) with a physical layer based on coded orthogonal frequency domain multiplexing (COFDM) modulation, delivering data rates up to 54Mb/s, operating in(More)
Fentanyl is an attractive agent for analgesia in the emergency department. Its use in this setting has been limited to IV bolus administration. We report successful sedation, muscle relaxation, and analgesia of a multiple trauma patient with fentanyl IV bolus and continuous infusion in the ED.
Instrumenting the new AGS (Alternating Gradient Synchrotron) Booster required the construction of a great deal of support electronics for many beam monitoring devices. Modules providing generic functions such as amplification, integration, sample and hold, etc., were designed and packaged so as to provide maximum flexibility in the implementation of typical(More)
1. The cellobiose/mannitol and 51Cr-labelled ethylenediaminetetra-acetate (51Cr-EDTA) absorption tests have been compared with respect to their ability to detect altered intestinal permeability in coeliac disease. 2. In patients with clinically proven coeliac disease, 13 out of 14 (93%) had abnormal urinary cellobiose/mannitol ratios, while only five out of(More)
Scintillating fiber tracking detectors are being developed for the SDC experiment at Superconducting Super Collider (SSC) and the upgrade of the D0 detector at the Fermilab Tevatron. The many attractive features of a fiber tracker include good position resolution, low occupancy, low mass in the active volume, and excellent resistance to radiation damage. An(More)
