Tri-Mode Hybrid Dielectric Resonator Antenna Fabricated via Laser-Based Selective Material Processing for WLAN Applications

IEEE Open Journal of Antennas and Propagation
In this paper, a novel tri-mode hybrid dielectric resonator antenna (DRA) designed for wireless local area network (WLAN) applications is presented. Through a special DRA design, the antenna profile is compressed to $0.05~\mathrm {\lambda }_{{0}}$ . TE $

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data

Advanced Engineering Materials, EarlyView.
Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.

Deciding Who's Legitimate: News Media Framing of Immigrants and Refugees

International Journal of Communication, 2017
With its relatively high immigration levels and comparatively favorable public opinion, Canada is often seen as a bastion of support for immigrants and refugees. We argue that support is uneven because Canadians differentiate between economic immigrants

CUILESS2016: a clinical corpus applying compositional normalization of text mentions

Journal of Biomedical Semantics, 2018
Background Traditionally text mention normalization corpora have normalized concepts to single ontology identifiers (“pre-coordinated concepts”). Less frequently, normalization corpora have used concepts with multiple identifiers (“post-coordinated ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Precise Local Positioning of a Mobile Device Based on Pose Reconstruction From a Visible Light Beacon

IEEE Access
This paper proposes an indoor positioning system for mobile devices using visible light beacons. The device’s camera is used to acquire images in which the beacon appears. An algorithm processes these images to reconstruct the camera’s pose
