Polarimetric SAR Speckle Reduction Based on Bilateral Filtering

open access: yesLeida xuebao, 2014
The priority during speckle reduction in Polarimetric Synthetic Aperture Radar (Pol-SAR) data is to maintain the polarization information. For this reason, it is undesirable to separate each element of polarimetric SAR.

Semi-supervised Learning for Classification of Polarimetric SAR Images Based on SVM-Wishart

open access: yesLeida xuebao, 2015
In this study, we propose a new semi-supervised classification method for Polarimetric SAR (PolSAR) images, aiming at handling the issue that the number of train set is small.

‘This funny place’: Uncovering the ambiguity of saltmarshes using a multimodal approach

open access: yesPeople and Nature, 2022
Saltmarshes are increasingly recognised for the range of benefits they offer, including coastal protection, flood regulation and carbon sequestration. However, much less is known about how people perceive these environments and their importance for non ...

HierTTS: Expressive End-to-End Text-to-Waveform Using a Multi-Scale Hierarchical Variational Auto-Encoder

open access: yesApplied Sciences, 2023
End-to-end text-to-speech (TTS) models that directly generate waveforms from text are gaining popularity. However, existing end-to-end models are still not natural enough in their prosodic expressiveness.

GLBR: A novel global load balancing routing scheme based on intelligent computing in partially disconnected wireless sensor networks

open access: yesInternational Journal of Distributed Sensor Networks, 2022
Load balancing is of great significance to extend the longevity of wireless sensor networks, due to the inherent imbalanced energy overhead in such networks.

Understanding collaborative supply chain relationships through the application of the Williamson organisational failure framework [PDF]

open access: yes, 2006
Many researchers have studied supply chain relationships however, the preponderance of open markets situations and ‘industry-style’ surveys have reduced the empirical focus on the dynamics of long-term, collaborative dyadic relationships.
