Generation of the Calibration Curve The time taken for a detectable change in signal is called detection time (DT), and it depends on the initial concentration of organisms, among some other factors. Calibration curves can be constructed relating the DT obtained to log10 of the initial bacteria...
multidimensional changepointwavelet transformationThe recently developed theory of wavelets has a remarkable ability to "zoom in" on very short-lived frequency phenomena, such as transients in signals and singularities in functions, and hence provides an ideal tool to study localized changes. This ...
4.7.1.4 Limitations of Unit Hydrograph The UH theory has the following limitations: 1. It cannot be applied to catchment areas greater than about 5000 km2, because for larger areas, the rainfall is not uniformly distributed and it does not remain constant. However, for larger areas, the catchm...

While I’m a huge advocate of the Laffer Curve in theory, I actually have very moderate views about the Laffer Curve in practice. For instance, I don’t think the Laffer Curve means all tax cuts pay for themselves. That only happens in very rare circumstances (see here and here). More...
Rogers创新采用曲线是对创新采用的各类人群进行研究归类的一种模型, 它的理论指导思想是在创新面前,部分人会比另一部分人思想更开放,更愿意采纳创新。 这个模型也被称之为,创新扩散理论(Diffusion of Innovations Theory),或多步创新流动理论(Multi-Step Flow Theory)。

A J Curve is an economic theory which states that, under certain assumptions, a country'strade deficitwill initially worsen after thedepreciation of its currency—mainly because in the near term higher prices on imports will have a greater impact on total nominal imports than the reduced volume o...
The Phillips curve is an economic theory that inflation and unemployment have a stable and inverse relationship. Developed by William Phillips, it claims that witheconomic growthcomes inflation, which in turn should lead to more jobs and less unemployment. The original concept of the Phillips curve ...
Elliptic curves have been intensively studied in algebraic geometry and number theory. In recent years they have been used in devising efficient algorithms... A Menezes - Springer US 被引量: 1722发表: 1993年 EFFICIENT MAPPING METHODS FOR ELLIPTIC CURVE CRYPTOSYSTEMS The generic name for collection...
