A Two-level Test Data Compression and Test Time Reduction Technique for SOC

, 2007
在單晶片系統日益成熟的紀元，巨大的測試資料量及極長的測試時間為其發展過程中所亟需克服的兩大問題。在本篇論文中，我們提出了一個單晶片系統層級中減低測試資料量及測試時間之兩階層式壓縮技巧。在第一階層中我們使用了選擇式霍夫曼編碼來對單晶片系統環境進行測試資料壓縮。於第二階層中我們藉由同時地廣播測試圖樣進入多個核心晶片來達成再一次的測試壓縮。最後我們使用d695為標的單晶片系統來進行實驗，得到了64%的測試資料壓縮及35%的測試時間壓縮。由於我們所提出的測試壓縮方法並不需要修改原有的核心晶片 ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

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.

Flexural Behavior of 3D‐Printed Porous Bouligand‐Structured Polymers: Influence of Pitch Angle and Porosity

Advanced Engineering Materials, EarlyView.
This study examines how helicoidal architectures with different porosities respond to bending. Adjusting layer angle and spacing in 3D‐printed polymers reveals clear tradeoffs between stiffness, strength, and energy absorption. Experiments and simulations highlight designs that distribute stress effectively, offering pathways for optimizing lightweight
