  • Here Is How Ithkuil Handles Mathematical Expressions and Units
    EXPRESSING MATHEMATICS AND MEASUREMENT IN ITHKUIL I have determined that, using existing Ithkuil morpho-phonology, morphology and morpho-syntax, there really isn’t an efficient way to state mathematical expressions in Ithkuil, including mathematical expressions involving units of measurement. Therefore, I’ve decided to create a formal sub-language within Ithkuil for dealing with mathematical expressions and units of measurement. You can think of this as a verbal analogy to the way that real-world written forms of mathematical expressions and rates of measurement require their own formal set of written symbols and symbolic notation rather than writing out mathematical expressions in words. Note that I have chosen to maintain the existing informal centesimal system without a root for zero as described in Chapter 12 of the Ithkuil website, as a means for efficiently conveying an everyday “naïve” means of doing counting and very basic arithmetical operations consistent with the morpho-phonology, morphology, and morpho-syntax of the Ithkuil language. At the same time, having a formal sub-language for higher mathematical expressions and measurement that follows its own internal morphological and syntactical rules allows for a succinct means of verbal mathematical expression and underscores the formalized, “special case” nature of mathematical expressions, again analagous to the formal written notation for mathematical expressions in real-world languages. This treatise is in two parts; the first part focusing on mathematical expressions, the second part on units of mearurement. MATHEMATICAL EXPRESSIONS Before introducing the new Ithkuil sub-language for formal mathematical expressions and measurement, I will first introduce the new Ithkuil roots, stems, and suffixes necessary for referencing higher mathematical concepts, terminology and expressions.

  • Phosphor Development: Synthesis, Characterization, and Chromatic Control by Dong Li
    AN ABSTRACT OF THE THESIS OF Dong Li for the degree of Doctor of Philosophy in Chemistry presented on April 6, 1999. Title: Phos hor Develo ment: S nthesis Characterization and Chromatic Control Redacted for privacy Abstract approved: / Douglas A. Keszler Selected phosphors of importance for continued development of flat-panel electroluminescent displays (ELDs) and field-emission displays (FEDs) have been synthesized andstudied. By using ceramic-processingmethods,solid-solution techniques, and codopants, the luminous efficiencies and chromaticities of several phosphors have been greatly improved.On the basis of these results, a trichromatic phosphor system has been proposed for upgrading ELD performance from monochrome to full-color capabilities. The maximum emission wavelength of Y2Si05:Ce3+ has been shifted by adding Sc to form the solid solution Y2..ScSiOs (0x 5_ 0.75.) Structures in thesolid-solution series were refined by the Rietveld method. The shift of the emission bandis associated with the distribution of Sc on the two crystallographic types of Y sites and the nephelauxetic effect. Eu2+-doped Mgi.CaxS luminescent powders were prepared by flowing H2S(g) over nanoparticulate Mgi_xCax0 that was prepared by the combustion method. The resulting materials were characterized by X-ray diffraction, scanning electron microscopy, and luminescence spectroscopy.The phosphor powder is characterized by faceted grains with a median particle size near 2p.m and a high cathodoluminescent efficiency: 8.07 lm/w at 2000V. GdNb04:Bi and YNbO4:Bi phosphors have been prepared by the sol-gel method. Compared to Y2SiO5:Ce, GdNbO4:Bi has a similar luminous efficiency, while YNbO4: Bi exhibits a higher efficiency.

THE ART OF ILLUMINATION BY LOUIS BELL, PH. D. OF THE UNIVERSITY NEW YORK McGRAW PUBLISHING CO. 114 LIBERTY STREET 1902 HALUDIE COPYRIGHTED, 1902, BY THE MCGRAW PUBLISHING COMPANY, NEW YORK. PREFACE. THIS volume is a study of the utilization of artificial light. It is intended to deal, not with the problem of dis- tributing illuminants, but with their application, and treats of the illuminants themselves only in so far as a knowl- edge of their peculiarities is necessary to their intelligent use. To compress the subject within reasonable bounds, it has been necessary to discuss general principles rather than concrete examples of artificial lighting. The science of producing light changes rapidly and the apparatus of yesterday may be discarded to-morrow, but the art of employing the materials at hand to produce the required results follows lines which are to a very considerable extent subject to fairly well-defined laws. Sins against these laws are all too common, the more so since artificial light has become relatively cheap and easy of applica- tion. If this outline of a complex art shall tend to avert even some of the commoner errors and failures in illumi- nation, it will have served its purpose. The author here desires to express his obligations to the beautiful treatise of M.

Reule Carl Zeiss, 7082 Oberkochen, Germany (May 26, 1976) . Based o~ simple principles, s l~ectrop hotoI?ct ry nevertheless demands a lot of precau­ tIOns to aVOi d errors. The followmg properties of spectrophotometers will be discussed together with methods to test them: ~pectra~ properties-wavelength accuracy, bandwidth, stray light; photometric linearity; mteractlOns between sample a~d instrument-multiple reflections, polarization, diver­ gence, sample wedge, sample tIlt, optical path length (refractive index), interferences. Calibratio~ of master instruments is feasiJ:>le only by complicated procedures. With such a master mstrument standards may be calIbrated which greatly simplify performance checks of mst:u:nen~s used for practical work. For testing high quality spcctrophotometcrs the u ~e of emiSSIOn lmes and nearly neutral absorbing solid filters as standards seems to be supenor, for some kinds of routine instruments the use of absorption bands and liquid filters may be necessary. Key words: Bandwidth; calibration; errors in spectrophotometry' interferences' multiple reflections; photometric linearity; polarization; sample characteri~tics; stray light; wave­ length accuracy.
