Designing, Implementing, and Evaluating AI Explanations: A Scoping Review of Explainable AI Frameworks

As AI systems become increasingly integrated into our lives, the need to support appropriate human understanding of AI continues to grow. With new AI capabilities being deployed in different contexts, human-centered explainability is crucial to ensure people can interact with novel AI systems safely and effectively. To address evolving explainability needs, the field of Explainable...

Encountering Deepfakes: A Thematic Analysis of Comments on a Music Video featuring Deepfake Content

Much early research on deepfakes has focused on speculating about potential future harms of the technology. Everyday uses and experiences of existing deepfake content are, surprisingly, comparatively understudied. For example, there is little research that seeks to understand how people encounter and respond to deepfake content in today’s entertainment media. In this study, we conducted...

Explainable Attention-Guided Swin Transformer Networks for Brain Tumor Segmentation from 3D MRI

This research presents a two-stage cascaded 3D segmentation approach designed for accurate brain tumor delineation in multimodal MRI data. The design incorporates a Swin Transformer backbone alongside Atrous Spatial Pyramid Pooling (ASPP) and Squeeze-and-Excitation (SE) blocks during the coarse segmentation phase to extract comprehensive, multi-scale contextual data. The second stage enhances the preliminary output with...

A Feasibility Study to Practically Implement a High-Performance Circularly Polarised Antenna Array for Point-to-Point Wireless Communication

ABSTRACT This article presents the design, fabrication and experimental validation of a compact linear series-fed microstrip antenna array with dual circular polarisation (CP) capability. The proposed structure consists of a $4times 4$ slotted circular patch array excited via four microstrip lines using a coplanar proximity coupling technique. Dual-CP operation is achieved through two miniaturised and...

Maintaining shared understanding of non-functional requirements in small companies using continuous software engineering

Non-functional requirements (NFR) such as performance and maintainability are key to overall software quality. To ensure NFRs can be satisfied, it is important that developers and other stakeholders have a shared understanding of such NFRs to prevent divergence of interpretations and expensive rework as a result. This article is part of a research program to...

Metasurface Effect on the Performance of Planar Antennas for Wireless Communications

Abstract This paper demonstrates the performance enhancement of a conventional planar antenna by incorporating metasurface (MTS) layer using a proposed unit-cell array. The impact of MTS unit-cell density on bit-error-rate (BER) and channel capacity (CC) in a point-to-point microwave link is investigated. The MTS layer is constructed from an array of identical unit-cells, including circular,...

Large-Scale Continuous Software Engineering: Exploring Three Dimensions of Transformation

This empirical study examines the transformation of a large-scale multinational software engineering organization into a product-oriented enterprise following Continuous Software Engineering (CSE) principles. Focusing on MarketCorp — a digital marketplace organization with distributed software development teams across multiple countries — the study explores the complex dimensions of transformation required for large-scale organizational change. Drawing on...
