Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Deriving iceberg ablation rates using an on-iceberg autonomous phase-sensitive radar (ApRES)
Annals of GlaciologyThe increase in iceberg discharge into the polar oceans highlights the importance of understanding how quickly icebergs are deteriorating and where the resulting freshwater injection is occurring.

Advanced Engineering Materials, EarlyView.This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

Annals of Glaciology, 2020 Numerical ice-sheet models are commonly matched to surface ice velocities from InSAR measurements by modifying basal drag, allowing the flow and form of the ice sheet to be simulated. Geophysical measurements of the bed are rarely used to examine if this

Radio echo-sounding of the Antarctic ice sheet.
Journal of the Japanese Society of Snow and Ice, 1989 氷床流動の観測に基づいて, 南極氷床の変動 (例えば, 氷床域の拡大, 縮小) を明らかにすることを目的として, 東南極の東経35度から東経45度に至るみずほ高原地域において, 過去20年にわたって観測が続けられてきた.その結果, 白瀬氷河流域では.年間約70cmもの氷厚の減少が観測された.この氷厚減少から, 白瀬氷河流域の氷床が不安定状態にあることが示唆され, 原因として, 氷床底面での“底面すぺり”が指摘された。そこで, 氷床底面の物理的状態を調べるために電波氷厚計を用いての電波探査が氷床上の流動測定・雪氷観測ルートに沿って, 1982年以降実施された.これまでの電波観測では, 送信時刻と基盤からの反射時刻の時間間隔から氷厚のみを求めていたが, この研究では, 氷床氷の厚さを測定するだけでなく,

Quantifying subglacial roughness and its link to glacial geomorphology and ice speed [PDF]
, 2013 The shape of subglacial bed topography, termed its roughness, is a recognised control on basal ice-flow. Although glaciologists have observed patterns of variations in ice speed over beds with different roughness values, the strength of this relationship

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

ImpDAR: an open-source impulse radar processor
Annals of Glaciology, 2020 Despite widespread use of radio-echo sounding (RES) in glaciology and broad distribution of processed radar products, the glaciological community has no standard software for processing impulse RES data.
