Summary: Developing liquid chromatography tandem mass spectrometry (LC-MS/MS) analyses of (bio)chemicals is both time consuming and challenging, largely because of the large number of LC and MS instrument parameters that need to be optimized. This bottleneck significantly impedes our ability to establish new (bio)analytical methods in fields such as pharmacology, metabolomics and pesticide rese...

In the Antarctic region, melting of sea ice and continental glaciers can create a surface lens of meltwater in coastal waters. When ice melts, particles concentrated within the ice are released into the water and can cause turbidity. Under these conditions, the optical properties of the water column are no longer related primarily to the phytoplankton and associated breakdown products (i.e., Ca...

The program’s general objective is to improve the variety, quantity, quality, and cost-effectiveness of observations in anticipation of a global ocean observing network of strategically placed moorings and other ocean platforms. Basic NOPP O-SCOPE goals are to: 1) identify key variables to be measured, determine capabilities and limitations of available sensors, and define specifications for ne...

Computer based analysis of human biological signals has advanced to a great extent over these years as they provide a cost effective and efficient way of detecting these signals. Signal acquisition in PC based systems may be automated by the use of LabVIEW or Bio-Bench software from National Instruments. This however requires to be supported by Data acquisition hardware units and drivers for cr...

The Coastal and Ocean Airborne Science Testbed (COAST) Project is a NASA Earth-science flight project that will advance coastal ecosystems research by providing a unique airborne payload optimized for remote sensing in the optically complex coastal zone. The COAST instrument suite combines a customized imaging spectrometer, sunphotometer system, and new bio-optical radiometer instruments to obt...

This paper describes the design of a monitoring system that can be used to measure urine glucose during daily life. It consists of a bio-chemical sensor, hardware with PIC microcontroller and control circuits, and signal analyzing part. To evaluate the performance, we compared the analyzed glucose levels of the developed system to a standard instrument, YSI glucose analyzer, based on regression...

This paper is intended as an investigation of new interactive environment for SHO (Japanese traditional instrument, a mouth organ like "Sheng" in China) performance. We have developed three styles of sensors for SHO performance with bio-sensor technology and microelectronics, designed a pattern recognizing module, and produced a multimedia / interactive environment for composition / performance...

Knowledge of tissue mechanical properties is widely required by medical applications, such as disease diagnostics, surgery operation, simulation, planning, and training. A new portable device, called Tissue Resonator Indenter Device (TRID), has been developed for measurement of regional viscoelastic properties of soft tissues at the Bio-instrument and Biomechanics Lab of the University of Toron...
