A circuit topology for high-swing, high-linearity
CMOS operational amplifiers has been developed. The
technique uses parallel-connected p- and n-channel
input pairs to realize an input common-mode voltage
range nearly equal to the total power supply voltage.
High linearity is achieved by summing the DC bias and
AC small-signal currents so...
This study uses an anthropological perspective
to discuss the cultural differences between Chinese
and Americans in business contexts. Through an
analysis of case studies related by businesspersons
involved in Sino-US trade, and by an analysis of
literature on the subject, it describes how cultural
differences contribute to the problems and...
This is a bibliography of doctoral dissertations and masters' theses in forestry and related topics issued during the period from July 1981 through June 1990. The colleges and universities included are all accredited by the Society of American Foresters. The actual listings were supplied by the individual institutions. Topics covered...
This thesis presents a systematic top-down methodology for simulating a phase-locked loop using a macro model in Verilog-A. The macromodel has been used to evaluate the jitter due to supply noise, thermal noise, and ground bounce. The noise simulation with the behavioral model is roughly 310 times faster (best case)...
Decision-making in environmental management is complex due to the multiplicity arid diversity of management objectives and technological choices. This suggests that modelers and experts could utilize (I) multiple-criteria decision-making (MCDM) approaches to assist stakeholder groups in integrating and synthesizing relevant data and information to address ecological and socio-economic concerns and...
PART I. The preparation of (-)-ibogamine (1) in fourteen steps from benzoquinone and in 10% overall yield is a powerful illustration of the value of the asymmetric Diels-Alder reaction as a starting point in a multistep synthesis. All four cycloadducts, 70, 77, 84 and 96, obtained with the (S)-BINOL-TiCl₂ complex...
This thesis presents an algorithm that estimates motion in image sequence using wavelet transform. The motion detection is performed under unfavorable conditions of background movement, change of brightness, and noise. The algorithm is tolerant to brightness changes, noise, and small movement in the background. The false alarm rate of motion...
This dissertation describes studies of isoprenoid biosynthesis in the
phytoflagellate Euglena gracilis. Elucidation of a novel isoprerioid pathway, the 2-Cmethyl-D-erythritol-4-phosphate (MEP) pathway, in addition to the generally known
mevalonate (MVA) pathway, led to extensive exploration of the distribution of both pathways in a variety of organisms. To date, photosynthetic eukaryotes...
MOTIVATION: The automatic identification of over-represented motifs present in a collection of sequences continues to be a challenging problem in computational biology. Many existing approaches to motif identification do not always find the relevant biological motifs, or find only a subset of the occurrences of a motif. In this paper,...
