Measurement of electromagnetic signal velocities in saturated fine-grained soils [PDF]

, 2010
Electromagnetic signal velocity measurements are common in soil disciplines, often involving Time-Domain Reflectometry. However, Time-Domain Reflectometry measurements are of limited use where velocity is frequency dependent, such as in finegrained soils.

Fine-Grained Semantic Novelty Detection [PDF]

, 2022
In this thesis, we introduce a new novelty detection problem - fine-grained semantic novelty detection. Specifically, given a text description d in natural language, we detect whether d represents a semantically novel phenomenon or not.
