With power and programming options, RS-232 or RS-485 communications capability, pushbutton calibration, and temperature-compensated signaling, LVU40 Series sensors bring another dimension of flexibility to continuous non-contact liquid level measurement. Highly accurate over their entire range of 0.3 to 18.3 m (1 to 60'), they incorporate filtering that virtually eliminates false echoes from peripheral obstructions. In conjunction with a PLC (programmable logic controller) or an OMEGA CNi Series controller, they can be used for point level measurement.

"Cleveland Clinic is proud to host this unique conference to discuss the measurement of healthcare outcomes and how these metrics can be used to produce high-quality outcomes," said Delos M. Cosgrove, M.D., CEO and President of Cleveland Clinic. "Moving forward, information and quality indicators for treatments and procedures will be critical to demonstrating value in healthcare and providing patients and other medical consumers with the substance they need to make informed choices. This summit will offer a timely and compelling program for this area of rapidly growing interest."

A graph of mean measurement over time is one of the most commonly used statistical graphs for data exploration and presentation. It can be as simple as a line plot, or can be a complex graph involving lots of annotation. Tags: Measurement, SAS Institute, Plot, Productivity White papers 2007-05-14

The concept of measurement is often misunderstood as merely the assignment of a value, but it is possible to assign a value in a way that is not a measurement in terms of the requirements of additive conjoint measurement. One may assign a value to a person's height, but unless it can be established that there is a correlation between measurements of height and empirical relations, it is not a measurement according to additive conjoint measurement theory. Likewise, computing and assigning arbitrary values, like the "book value" of an asset in accounting, is not a measurement because it does not satisfy the necessary criteria.

In the classical definition, which is standard throughout the physical sciences, measurement is the determination or estimation of ratios of quantities. Quantity and measurement are mutually defined: quantitative attributes are those which it is possible to measure, at least in principle. The classical concept of quantity can be traced back to John Wallis and Isaac Newton, and was foreshadowed in Euclid's Elements (Michell, 1993).

Results That Matter and the new website [W]ww.resultsthatmatter.net present a new "Effective Community Governance Model" that emphasizes how performance measurement and citizen engagement can be used together to foster continual community improvement. The book (available at http://www.josseybass.com/WileyCDA/WileyTitle/productCd-0787960586.html) features case studies from across the country that illustrate how governments and nonprofit organizations measure and improve performance, engage citizens in decision and planning processes, and use both "managing for results" and "governing for results" cycles to achieve results that matter most to the people of the community.
