Physics of Binary Star Evolution: From Stars to X-Ray Binaries and Gravitational Wave Sources

為了解決Telescope的問題，作者Tauris, Thomas M.,Van Den Heuvel, Edward P. J. 這樣論述：

A graduate-level textbook on the astrophysics of binary star systems and their evolutionPhysics of Binary Star Evolution is an up-to-date textbook on the astrophysics and evolution of binary star systems. Theoretical astrophysicists Thomas Tauris and Edward van den Heuvel cover a wide range of ph

enomena and processes, including mass transfer and ejection, common envelopes, novae and supernovae, X-ray binaries, millisecond radio pulsars, and gravitational wave (GW) sources, and their links to stellar evolution. The authors walk through the observed properties and evolution of different types

of binaries, with special emphasis on those containing compact objects (neutron stars, black holes, and white dwarfs). Attention is given to the formation mechanisms of GW sources--merging double neutron stars and black holes as well as ultra-compact GW binaries hosting white dwarfs--and to the pro

genitors of these sources and how they are observed with radio telescopes, X-ray satellites, and GW detectors (LIGO, Virgo, KAGRA, Einstein Telescope, Cosmic Explorer, and LISA). Supported by illustrations, equations, and exercises, Physics of Binary Star Evolution combines theory and observations t

Automated Vision-based Post-Earthquake Safety Assessment for Bridge Using STF-PointRend and EfficientNetB0

為了解決Telescope的問題，作者Kenneth Harsono 這樣論述：

Structural health monitoring (SHM) on the bridge is important to know the usability of the bridges. However, conventional inspection is labor-intensive and expensive. This method is not suitable for post-earthquake inspections that require speed and consistency. Therefore, this research aims to dev

elop an automated bridge inspection using STF-PointRend and EfficientNetB0. The STF-PointRend consists of two-part, namely symbiotic organism search as a hyper-parameter optimizer and PointRend as semantic segmentation. This model is used to recognize the component and the damage type which will be

used to get the percentage of the damaged component. On the other hand, the EfficientNetB0 uses as the image classifier. The output of this model is used to get the damage level from each component. As a base to determine the safety of the bridge, this study uses the degree of earthquake resistance.

This rating system is based on the DERU method but only considers the structural component. The result shows that STF-PointRend gets a good testing result with the mIoU of 82.67% and 71.42% for component and damage detection. Meanwhile, the EfficientNet got an average F1score of 0.85912 for the tes

ting dataset. For further evaluation, this research uses two minor bridges that suffered catastrophic earthquakes from Palu Earthquake in 2018. The evaluation shows that both bridges need maintenance as soon as possible.

探索LIGO O3訊號中的暗星

為了解決Telescope的問題，作者黃柏翔 這樣論述：

自從aLIGO重力波探測器在2015年9月14日首次直接探測到愛因斯坦廣義相對論中所預測的重力波訊號後，在現今的宇宙探索中重力波已扮演了不可獲缺的角色，由於重力波所造成的時空漣漪效應不大，因此實驗團隊不停的在各方面精進探測器的靈敏度以達到更精準的量測，目前的探測器以數個或數十個太陽質量的雙星系統互繞和進一步併合的事件為主。然而也因為重力波在傳遞的過程中不像光子或其他宇宙射線粒子容易受到干擾，所以可以更完整的保留星體合併事件中的質量、自旋等數據。在美國雷射干涉儀重力波觀測站（aLIGO)的第一次觀測（O1）與第二次觀測（O2）中首次探測出雙黑洞與雙中子星合併的訊號，這些珍貴的資料提供了科學家們

研究元素生成、星體演化以及黑洞、中子星分佈等重要的訊息。然而眾所週知，宇宙的量密度占比中，已知的標準粒子的佔比大約為5\%，而約20\%的能量密度為未知的暗物質所組成，暗物質的能量密度是一般物質的4-5倍且對於星系結構的形成扮演決定性的角色。另外目前的理論上仍存有暗物質形成緊緻星體的可能性，若該機制確實發生在宇宙星際，這樣的暗星體的豐度將不可忽略。在此研究中，我們假設暗物質為純量基本粒子，該組成的暗星又稱為玻色星，這樣的特異星體和標準星體如黑洞和中子星的最大差異在於不參與電磁交互作用，且暗星體理論上的緊緻度與形變量也和其基本物理量息息相關，如暗物質粒子質量、自相交互作用強度以及狀態方程式等，導

致其在雙星系統中相對應的變化量會隱藏於星體合併產生的重力波波形中。本篇主要使用aLIGO第三次觀測（O3）的上半年數據並使用PyCBC（A Python-based parameter estimation toolkit for c ompact binary coalescence signals.）分析去挖掘是否有玻色星合併的潛在事件。
