Dasymetric Modeling and Uncertainty [PDF]

open access: yesAnnals of the Association of American Geographers, 2013
Dasymetric models increase the spatial resolution of population data by incorporating related ancillary data layers. The role of uncertainty in dasymetric modeling has not been fully addressed as of yet. Uncertainty is usually present because most population data are themselves uncertain, and/or the geographic processes that connect population and the ...

On the Combination of Physical Parameterization Schemes for Tropical Cyclone Track and Intensity Forecasts in the Context of Uncertainty

open access: yesJournal of Advances in Modeling Earth Systems, 2023
The selection of physical parameterization schemes for tropical cyclone (TC) forecasts has required a substantial amount of effort. In general, the evaluation of physical parameterization schemes and their combined performance was based solely on the ...

Biomass Estimation and Uncertainty Quantification From Tree Height

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
We propose a tree-level biomass estimation model approximating allometric equations by LiDAR data. Since tree crown diameter estimation is challenging from spaceborne LiDAR measurements, we develop a model to correlate tree height with biomass on the ...

Robust Sliding Mode Control With Optimal Path Following for Lateral Motion of Autonomous Bus

open access: yesIEEE Access, 2023
A robust and high-performance lateral control system is necessary for autonomous bus driving in complex downtown roads. In this paper, a Sliding Mode (SM) controller with an uncertainty observer is proposed to reduce the chattering phenomenon while ...

UNCERTAINTY IN TMDL MODELS [PDF]

open access: yesTransactions of the ASABE, 2006
Although the U.S. Congress established the Total Maximum Daily Load (TMDL) program in the original Clean Water Act of 1972, Section 303(d), it did not receive attention until the 1990s. Currently, two methods are available for tracking pollution in the environment and assessing the effectiveness of the TMDL process on improving the quality of impaired ...

Quantification and Evaluation of Parameter and Model Uncertainty for Passive and Active Vibration Isolation

open access: yes, 2022
S.135-147Vibration isolation is a common method used for minimizing the vibration of dynamic load-bearing structures in a region past the resonance frequency, when excited by disturbances.

Model Uncertainty and Liquidity [PDF]

open access: yesSSRN Electronic Journal, 2002
Extreme market outcomes are often followed by a lack of liquidity and a lack of trade. This market collapse seems particularly acute for markets where traders rely heavily on a specific empirical model such as in derivative markets like the market for mortgage backed securities or credit derivatives.

Parameter identification method for multibody systems incorporating the adjoint method and feature extraction based on the proper orthogonal decomposition

open access: yesNihon Kikai Gakkai ronbunshu, 2023
Many mechanical systems such as vehicles, robots and space structures are comprised of a lot of interconnected components. The motion of the components is constrained because of mechanical joints or specified motion trajectories.
