To meet those goals, calibration and validation pre‐launch and on‐orbit methods formed a basis of the calibration and validation concept, including the combined use of on‐board references, vicarious techniques, and routine lunar imaging. International collaboration with space agencies in o...
Additional inputs for calibration and validation can be gained from the ocean-wide spreading of animal-borne cameras43, particularly from species using windrows as feeding spots. Citizen science could also contribute with opportunistic observations whereas from leisure vessels, fishing, or commercial ...
Design and error analysis of a high accurate star simulator based on optical splicing technology Dynamic tar simulator has been widely used in calibration and validation for star trackers.To achieve both high accuracy and large view field,a dynamic sta... LIU,Zengyi,ZHAO,... - 《仪器仪表学报:...
This proof-of-concept study explores quantitative imaging of articular cartilage using photon-counting detector computed tomography (PCD-CT) with a dual-contrast agent approach, comparing it to clinical dual-energy CT (DECT). The diffusion of cationic iodinated CA4 + and non-ionic gadolinium-ba...
This paper outlines the activities performed with a special focus on system calibration and validation procedures, as well as preliminary measurement results. 展开 关键词: aerospace testing calibration data acquisition spectrometers APEX Earth observation airborne prism experiment airborne pushbroom imaging ...
To date, the concept of narrow‐sense validity has been under-appreciated and not widely pursued. 到目前为止,狭义效度的概念一直没有得到足够的重视,也没有得到广泛的应用。 Furthermore, although methods for measuring calibration of prediction models are well developed, they have not been adopted for ...
This obviates the need to perform sensor-to-segment calibration and so drastically improves results. Teufl, Lorenz [40] observed an average joint angle nRMSE < 7%; our TFA data was under this threshold in three out of eight results (knee on both legs and ankle on the amputated side)....
The relationship between the RS observations and ecosystem models is also undergoing a paradigm shift. The different national aerospace agencies are currently in a major research phase of calibration and validation of the new instruments, which should provide a continuing string of independent tests for...
Positron Emission Tomography (PET) is a well-known imaging technology for the diagnosis, treatment, and monitoring of several diseases. Most PET scanners use a Ring-Shaped Detector Configuration (RSDC), which helps obtain homogeneous image quality but ar
Concept drift means that the distribution of the data changes over time, in which case the assumptions made by the regression model break down, resulting in regression estimates with unknown and possibly large errors. For example, in sensor calibration a regression model trained to model the ...
