The thiocyanate dosimeter (10–2 mol dm–3 SCN– in O2-saturated water) has been standardised against the super-Fricke dosimeter (10–2 mol dm–3 FeII in O2-saturated 0.4 mol dm–3 H2SO4) using the hexacyanoferrate(II) dosimeter [5 × 10–3 mol dm–3 Fe(CN)64– in O2-saturated water] as a secondary standard. On the basis that G…
Polycrystalline, transparent YAG (Y 3 AI 5 O 12 ) ceramics were fabricated by a solid‐state reaction method using high‐purity Al 2 O 3 and Y 2 O 3 powders. The mixed powder compacts were sintered at 1600° to 1850°C for 5 h under vacuum. Optical transmittance in the region between the ultraviolet and infrared wavelengt…
For a system with hysteresis, the authors present a parameterized hysteresis model and develop a hysteresis inverse. The authors then design adaptive controllers with an adaptive hysteresis inverse for plants with unknown hysteresis. A new adaptive controller structure is introduced which is capable of achieving a lin…

Electrochromism: Fundamentals and Applications is the first in-depth treatise on the topic. Written by leading scientists in the field, it is a state-of-the-art account of all aspects of electrochromism, presented at a level accessible to chemists, physicists, materials scientists and engineers. Both the physical and…
An important tool for improving the reliability of HV insulation systems are partial discharge (PD) measurements. The interpretation of such measurements aims at extracting from the measured data information about insulation defects which then are used for estimating the risk of insulation failure of the equipment. Be…

Carbon dioxide corrosion of carbon steel has been studied as a function of CO{sub 2} partial pressure (0.05 to 2.1 MPa), temperature (20, 40 60 and 90 C), pH (4 to 6) and flow velocity (0.1, 3.1, 8.5, and 13 m/s) under conditions where protective iron carbonate fare do not form. The experiments were carried out under…
Rietveld analysis is a means of revealing the detailed structure and composition of a polycrystalline sample using X-ray or neutron powder diffraction data. A starting model of the material is used to calculate an entire diffraction pattern. The model parameters (and hence the calculated pattern) are refined by the me…

This symposium consisted of seven platform sessions: hydrogen effects; pressure tubes; fabrication; lithium effects and second phase particles; mechanical properties; oxide characterization; and in-reactor corrosion. The technical information contained in this book is valuable to zirconium alloy producers, nuclear fue…
Fluorine-doped silica active and passive optical fibers for different purposes have been fabricated by two novel modifications of the plasmachemical technology. These versions of the technology are shown to be convenient in laboratory conditions and very promising in developing various types of special fibers with non…
The magnetic relaxation of ferromagnetic powders has been studied for many years, largely due to its importance to recording technologies. However, only recently have experiments been performed that resolve the magnetic state of individual sub-micron particles. Motivated by these experimental developments, we use drop…
