Slim: Explicit Slot-Intent Mapping With Bert For Joint Multi-Intent Detection And Slot Filling

Boi Faltings, Fei Mi, Fengyu Cai, Wanhao Zhou

Utterance-level intent detection and token-level slot filling are two key tasks for spoken language understanding (SLU) in task-oriented systems. Most existing approaches assume that only a single intent exists in an utterance. However, there are often mul ...

Development of High-Strength Aluminum Alloys for Additive Manufacturing

Marvin Lennard Schuster

Metal additive manufacturing (AM) offers the possibility to rapidly produce complex geometries that are not achievable with conventional manufacturing methods. The two most common technologies, Laser Powder Bed Fusion (LPBF) and Direct Metal Deposition (DM ...

Microstructure Selection in Laser Remelted Fe-C-Si Alloys

Wilfried Kurz, Philippe Gilgien

Laser surface remelting at various velocities has been employed to study the selection of microstructures of high-purity Fe-C-Si alloys containing nominally 3.2 to 4.2 wt.% C and 1 to 3 wt.% Si. The microstructure of the remelted region consisted of metast ...

Imaging the Heterogeneity of the Oxygen Evolution Reaction on Gold Electrodes Operando: Activity is Highly Local

Sylvie Roke, Arianna Marchioro, Igor Nahálka

Understanding the mechanism of the oxygen evolution reaction (OER), the oxidative half of electrolytic water splitting, has proven challenging. Perhaps the largest hurdle has been gaining experimental insight into the active site of the electrocatalyst use ...

High Performance Tri-gate GaN Power MOSHEMTs on Silicon Substrate

Elison de Nazareth Matioli, Jun Ma

We demonstrate high-performance GaN power metal-oxide-semiconductor high electron mobility transistors (MOSHEMTs) on silicon substrate based on a nanowire tri-gate architecture. The common issue of partial removal of carriers by nanowire etching in GaN tri ...

Metal artefact reduction in computed tomography images by a fourth-order total variation flow

Alfio Quarteroni, Elena Faggiano

Permanent metallic implants, such as dental fillings and cardiac devices, generate streaks-like artefacts in computed tomography (CT) images. In this article, we propose a strategy to perform metal artefact reduction (MAR) that relies on the total variatio ...

On the micrometre precise mould filling of liquid polymer derived ceramic precursor for 300-µm-thick high aspect ratio ceramic MEMS

Jürgen Brugger, Rosario Maurizio Gullo, Jonas Grossenbacher

This paper describes a novel and scalable method for the fabrication of polymer derived ceramics (PDC) structures with high aspect ratio and micrometre scale features. Elastomeric micro-moulds composed of a filling pot are used to deliver via sacrificial m ...

Infiltration of tin bronze into alumina particle beds: influence of alloy chemistry on drainage curves

Andreas Mortensen, Ludger Weber, Alain Léger

The wetting of angular alumina particle preforms by Cu-Sn alloys is investigated by means of pressure infiltration experiments conducted at 1150 A degrees C, using a system enabling dynamic and precise measurements of the metal volume injected into the pre ...

Role of filling materials in a P-wave interaction with a rock fracture

Jian Zhao, Wei Wu

The purpose of this study is to investigate the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture. The specific fracture stiffness reflects the seismic response of a filled fracture, while ...

Isothermal Ageing of SnAgCu Solder Alloys: Three-Dimensional Morphometry Analysis of Microstructural Evolution and Its Effects on Mechanical Response

John Botsis, Joël Cugnoni, Milad Maleki

Due to the high homologous temperature and fast cooling rates, the microstructures of SnAgCu (SAC) solders are in a meta-stable state in most applications, which is the cause of significant microstructural evolution and continuous variation in the mechanic ...
