Reversible secret image sharing scheme based on difference expansion
, 2013 碩士(t, n)門檻式機密影像分享技術是將機密影像分成n張無意義的分享影像並分配給n位參與者，其中任何超過t位參與者的群組，都能利用他們的分享影像還原機密影像。反之，則不能還原機密影像。同時，為降低分享影像的顯著性，可進一步藉由偽裝學(Steganography)技術，將分享影像藏入有意義的掩護影像中形成一張偽裝影像，來避免攻擊者的注意力與提供管理上的便利性。本文提出結合偽裝學技術的可逆機密影像分享技術，讓參與者在還原過程中，除了可以從偽裝影像中擷取機密影像外，還可以將偽裝影像回復成掩護影像 ...

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

An improved boolean-based multiple secret images sharing scheme for different sized secret images
, 2016 碩士本論文提出一個可以處理相異尺寸的多重秘密影像分享技術，在此技術中又有兩種處理方式，先將不同尺寸的秘密影像做統一的處理，再利用雜湊函數還有亂數種子產生出亂數影像，透過亂數影像和秘密影像做布林函式運算，最後產出分享影像，在處理的過程中都是利用基本運算，所以在效能上有很好的效率，在安全性上也達成了秘密影像分享的效果，最後更能處理更多不同尺寸的影像。相較其他學者所提出的分享方法，本論文針對多樣性及安全性兩方面做了更佳的改進。在安全性方面，本文採取有幾張秘密影像就生成幾張亂數影像，在得到分享影像時 ...

Deep Underground Science and Engineering, EarlyView.The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
