Improved Active Deep Learning for Semi-Supervised Classification of Hyperspectral Image

open access: yesRemote Sensing, 2021
Hyperspectral image (HSI) data classification often faces the problem of the scarcity of labeled samples, which is considered to be one of the major challenges in the field of remote sensing.

A New SCAE-MT Classification Model for Hyperspectral Remote Sensing Images

open access: yesSensors, 2022
Hyperspectral remote sensing images (HRSI) have the characteristics of foreign objects with the same spectrum. As it is difficult to label samples manually, the hyperspectral remote sensing images are understood to be typical “small sample” datasets ...

Gaseous radiocarbon measurements of small samples [PDF]

open access: yes, 2010
Radiocarbon dating by means of accelerator mass spectrometry (AMS) is a well-established method for samples containing carbon in the milligram range. However, the measurement of small samples containing less than 50 lg carbon often fails. It is difficult

The mechanical properties at room and low temperature of P110 steel characterised by means of small punch test [PDF]

open access: yesArchives of Metallurgy and Materials, 2019
In this paper small punch test (SPT) which is one of miniaturized samples technique, was employed to characterize the mechanical properties of carbon steel P110. The tests were carried out in the range of –175°C to RT.
