It has been suggested by other investigators that the extent of neutral and acid steroid conversion by human intestinal flora may be correlated with large-bowel carcinogenesis. Within a population of 31 normal North Americans, we found that two distinct patterns of neutral steroid conversion could be detected by gas-liquid Chromatographie procedures. One pattern was characterized by extensive c...

We report observations of saturation effects in a Ce:LuAG and Eu-doped nitride ceramic phosphor for conversion of blue laser light for white light generation. The luminous flux from the phosphors material increases linearly with the input power until saturation effects limit the conversion. It is shown that the temperature of the phosphor layer influences the saturation power level and the conv...

In many high-level signal processing tasks, such as pitch shifting, voice conversion or sound synthesis, accurate spectral processing is required. Here, the use of Radial Basis Function Networks (RBFN) is proposed for modeling the relationships among sets of spectral envelopes. The identification of such conversion functions is based on a procedure which learns the shape of the conversion from ...

Two of the main challenges recent electric vehicles (EVs) are charging time and high initial cost. To solve problem associated with long time, car manufacturers moving from 400 V battery EV (BEV) to 800 BEV, which enables utilization multi-level converters in applications. This paper presents a power conversion system consisting Vienna rectifier two/three level hybrid inverter as machine-side d...

In smart manufacturing, engineers typically analyze unexpected real-time problems using digitally cloned discrete-event (DE) models for wafer fabrication. To achieve a faster response to problems, it is essential increase the speed of DE simulations because making optimal decisions addressing issues requires repeated simulations. This paper presents hierarchical aggregation/disaggregation (A/D)...

The field-effect enzymatic detection (FEED) technique was used to control the kinetics of the enzymatic conversion of glucose to gluconolactone. The glucose-gluconolactone conversion occurring at an enzyme-immobilized electrode, a well-studied process, was confirmed using mass spectrometry. Electrochemical studies showed that the glucose oxidation current depends on the gating voltage VG and th...

Prosody plays an important role in neutral-to-emotional voice conversion. Prosodic features like pitch are usually estimated and altered at a segmental level based on short windowing of speech signal (where the signal is expected to be quasi-stationary). This results in a frame-wise change of acoustical parameters for synthesizing emotionalized speech. In order to convert a neutral speech to an...
