A Transformer-Based Framework for Parameter Learning of a Land Surface Hydrological Process Model

open access: yesRemote Sensing, 2023
The effective representation of land surface hydrological models strongly relies on spatially varying parameters that require calibration. Well-calibrated physical models can effectively propagate observed information to unobserved variables, but ...

Accelerating Point Cloud Computation via Memory in Embedded Structured Light Cameras

open access: yesJournal of Imaging
Embedded structured light cameras have been widely applied in various fields. However, due to constraints such as insufficient computing resources, it remains difficult to achieve high-speed structured light point cloud computation. To address this issue,

Calibration in Temperature of Photometric Parameters [PDF]

open access: yesSymposium - International Astronomical Union, 1985
It is very easy to use a Planck distribution to show that a color index is a temperature parameter, but it is more difficult to calibrate such a color index in terms of temperature because only a few Teff values are determined. A pioneering work is that of Kuiper (1938), who derived a temperature scale according to spectral type (from A0 to M2 for ...

Traffic simulation optimization considering driving styles

open access: yesCommunications in Transportation Research
Parameter calibration is essential for ensuring the accuracy of microscopic traffic simulations. The expected speed is a critical parameter that characterizes behaviors of vehicles in most simulation models, which is influenced by road traffic conditions

Multi-criteria calibration of a conceptual runoff model using a genetic algorithm [PDF]

open access: yesHydrology and Earth System Sciences, 2000
: Calibration of a model against more than one output variable is important for reliable simulations of internal processes. In this study, a genetic algorithm combined with local optimisation was proposed for automatic single- and multi-criteria ...

Calibration of a Rotating or Revolving Platform with a LiDAR Sensor

open access: yesApplied Sciences, 2019
Perceiving its environment in 3D is an important ability for a modern robot. Today, this is often done using LiDARs which come with a strongly limited field of view (FOV), however.
