Calcium intake level was far below the Dietary Reference Intake and dairy product consumption was inconsistent with the Daily Dietary Guidelines among adolescents in Taiwan...
Digital-to-analog converters (DACs) with wide dynamic range and high
linearity are required for high-end audio applications. A multi-bit delta sigma
audio DAC, using a novel gain-correction technique, is described in this thesis. For
widely varying on-chip RC time constant, the DAC gain can be accurately
controlled by the correction circuitry....
The LifeKnowledge curriculum is a recent initiative of the National FFA Organization to develop key learning precepts in agriculture education students.

Sickle cell disease (SCD) is a phenotypically variable disorder of hemoglobin that leads to abnormally shaped and dysfunctional red blood cells. Several studies have attempted to construct early predictive models for SCD, including Miller et al.’s (2000) model which uses easily identifiable predictors in early life. The primary aim of...
Surface acoustic wave (SAW) sensors are versatile devices that can be configured to sense a variety of measurands such as temperature and pressure. The potential use of surface acoustic wave devices for magnetic field detection is explored in this study. Compared to current magnetic field sensors, a sensor based on...
Massively multiplayer role-playing games (MMORPG) are becoming a popular leisure activity world-wide. MMORPG players have created a new kind of market, one for virtual possessions. Some players will buy and sell virtual goods for real-world money. Many game developers oppose this real-market trade because it threatens the control of their...
As broadband Internet becomes widely available, Peer-to-Peer (P2P) applications over the Internet are becoming increasingly popular. Such an example is a video multicast application in which, one source streams a video to a large number of destination nodes through an overlay multicast tree consisting of peers.
These overlay multicast-based applications,...
