Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Indoor Localization for Wireless Sensor Networks
, 2007 在無線感測器網路中，位置(即座標)是一項非常重要的資訊，這是因為有需多的感測器網路應用都會需要使用到此資訊，如安全監視系統，燈光控制系統，火警系統等等,而室內環境中複雜的電磁波傳輸特性是室內定位演算法遭遇的一個大問題。我們經觀察後發現目前對於室內定位演算法的研究大部分是先將大量的事前知識先輸入給網路中的幾個特定感測器在進行定位計算，透過這種方式獲得的定位準確度雖然相當精確，但是同時也需要在定位之前執行需多的準備工作。因此在本篇論文當中，我們提出一個只需要非常少量事前知識的無線感測器網路室內定位演算法 ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology
Deep Underground Science and Engineering, EarlyView.This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

EcoEnergy, EarlyView.This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

EcoEnergy, EarlyView.A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,
