the runoff simulation in a watershed provides insight on the processes affecting runoff generation and the stream flow characteristics like spatial and temporal variability of stream flow. this insight helps managers and planners in informed decision-makings on water resources management and planning. the objective of this study is to compare the performances of the complex swat model and the s...

The derivation of radiometric specifications for imaging spectrometers from the visible to the short-wave infrared part of the spectrum is a task based on the requirements of potential scientific applications. A method for modeling the noise equivalent radiance at-sensor level is proposed. The model starts with surface reflectance signatures, transforms them to at-sensor signatures, and combine...

The equity premium, namely the expected return on the aggregate stock market less the government bill rate, is of central importance to the portfolio allocation of individuals, to the investment decisions of firms, and to model calibration and testing. This quantity is usually estimated from the sample average excess return. We propose an alternative estimator, based on maximum likelihood, that...

Accident prediction models, also known as safety performance functions, have several important uses in modern day safety analysis. Unfortunately, calibration of these models is not straightforward. This paper documents a research effort that demonstrates the complexity of calibrating these models for urban intersections. These complexities relate to the specification of the functional form, the...
