This paper describes a modification to, and a fast implementation of, the Viterbi algorithm for use in stochastic lettertophoneme conversion. A straightforward (but unrealistic) implementation of the Viterbi algorithm has a linear time complexity with respect to the length of the letter string, but quadratic complexity if we additionally consider the number of lettertophoneme correspondences to be a variable determining the problem size. Since the number of correspondences can be large, processing time is long. If the correspondences are precompiled to a deterministic finitestate automaton to simplify the process of matching to determine state survivors, execution time is reduced by a large multiplicative factor. Speedup is inferred indirectly since the straightforward implementation of Viterbi decoding is too slow for practical comparison, and ranges between about 200 and 4000 depending upon the number of letters processed and the particular correspondences employed in the transdu...

A scalable, multiplexed ion trap for quantum information processing is fabricated and tested. The trap design and fabrication process are optimized for scalability to small trap size and large numbers of interconnected traps, and for integration of control electronics and optics. Multiple traps with similar designs are tested with 111 Cd +, 25 Mg +, and 88 Sr + ions at room temperature and with 88 Sr + at 6 K, with respective ion lifetimes of 90 s, 300 ± 30 s, 56 ± 6 s, and 4.5 ± 1.1 hours. The motional heating rate for 25 Mg + at room temperature and a trap frequency of 1.6 MHz is measured to be 7 ± 3 quanta per millisecond. For 88 Sr + at 6 K and 540 kHz the heating rate is measured to be 220 ± 30 quanta per second.

The duration of my Ph.D. study in the computer sciences department at the University of Texas at Austin is an interesting period of my life that I will always treasure. People in different circles have touched my life in this period. I wish to thank all of them sincerely from the bottom of my heart. Foremost, on the academic front, I wish to thank my committee members, especially my advisor Dr. Martin D.F. Wong, for their guidance and patience, without which this manuscript would not have been possible. I also would like to thank my fellow classmate and good friend Dr. Xiaoping Tang. Dr. Tang was very generous in providing collaboration for various research topics we worked on together. In addition, Dr. Tang provided many entertaining discussions—many times on topics not related to research—we had had in the courtyard of Taylor Hall. Dr. Xiaoping Tang is certainly one of the smartest people I have ever had the privilege to meet. At my job at Motorola, my thanks first go to Dr. Warren Grobman and Dr. Alfred Reich for their helps and encouragements on my Ph.D. pursuit. I would also like to express my deepest gratitude to my colleagues Mr.
ASTRONOMY AND ASTROPHYSICS ISOCAM in flight?
, 1996
"... Abstract. ISOCAM, the camera on–board ISO, takes images of the sky in the wavelength range 2.5 to 18 m. It features two independent channels, containing each a 32 32 pixel detector: the short wavelength channel – 2.5 to 5.5 m, and the long wavelength channel – 4 to 18 m. Each channel features 10 or ..."

Abstract. ISOCAM, the camera on–board ISO, takes images of the sky in the wavelength range 2.5 to 18 m. It features two independent channels, containing each a 32 32 pixel detector: the short wavelength channel – 2.5 to 5.5 m, and the long wavelength channel – 4 to 18 m. Each channel features 10 or 11 discrete band pass filters and CVFs with a resolution better than 35. Each channel is fitted with a set of lenses, which reimage the focal plane of the telescope on the array, yielding a pixel field of view of 1.5, 3, 6 or 12 arcsec. Throughout the development cycle, ISOCAM has been carefully calibrated, first at component level

Portable sawmilling trials with Acacia aneura (mulga) and A. cambagei (gidgee) have been undertaken to estimate the private landholder costs associated with smallscale timber production from woodlands in western Queensland, Australia. A time study of harvesting and milling operations facilitated estimation of landholder labour input requirements. The scarcity and small size of millable logs, coupled with the prevalence of timber defects, make harvesting and portable sawmilling of western Queensland acacias an expensive undertaking for landholders. The cost of producing sawn timber that meets the High Feature (HF) grade of Australian Standard AS2796 is estimated at between A$3,000/m 3 and A$3,400/m 3 of HF timber.
