Identity, Culture, and the Science Performance, Volume 1: From the Lab to the Streets

為了解決RE: LAB的問題，作者 這樣論述：

Identity, Culture, and the Science Performance, Volume 1: From the Lab to the Streets is the first of two volumes dedicated to the diverse sociocultural work of science-oriented performance. A dynamic volume of scholarly essays, interviews with scientists and artists, and creative entries, it exa

mines explicitly public-facing science performances that operate within and for specialist and non-specialist populations. The book’s chapters trace the theatrical and ethical contours of live science events, re-enact historical stagings of scientific expertise, and demonstrate the pedagogical and

activist potentials in performing science in community settings. Alongside the scholarly chapters, From the Lab to the Streets features creative work by contemporary science-integrative artists and interviews with popular science communicators Sahana Srinivasan (host of Netflix’s Brainchild) and Rav

en Baxter (＂Raven the Science Maven＂) and artists from performance ensembles The Olimpias and Superhero Clubhouse. In exploring the science performance as a vital but flawed method of public engagement, it offers a critique of the racist, ableist, sexist, and heteronormative ideologies prevalent ac

ross the history of science, as well as highlighting science performances that challenge and redress these ideologies. Along with its complementary volume From the Curious to the Quantum, this book documents the varied ways in which identity categories and cultural constructs are formed and reformed

through science performances.

低腔壓高濃度過氧化氫混合式火箭引擎之研究

為了解決RE: LAB的問題，作者林育宏 這樣論述：

本論文為混合式火箭系統入軌段火箭引擎的前期研究，除了高引擎效率的要求外，更需要精準的推力控制與降低入軌段火箭的結構重量比，以增加入軌精度與酬載能力。混合式火箭引擎具相對安全、綠色環保、可推力控制、管路簡單、低成本等優點，並且可以輕易地達到引擎深度節流推力控制，對於僅能單次使用、需要精準進入軌道的入軌段火箭推進系統有相當大的應用潛力。其最大的優點是燃料在常溫下為固態、易保存且安全，即使燃燒室或儲存槽受損，固態的燃料也不會因此產生劇烈的燃燒而導致爆炸。雖然混合式推進系統有不少優於固態及液態推進系統的特性，相較事先預混燃料與氧化劑的固態推進系統及可精準控制氧燃比而達到高度燃燒效率的液態推進系統，混

合式推進系統有擴散焰邊界層燃燒特性，此因素導致混合式推進系統的燃料燃燒速率普遍偏低，使得設計大推力引擎設計時需要長度較長的燃燒室來提供足夠的燃料燃燒表面積，也導致得更高長徑比的火箭設計。針對此問題，本論文利用渦漩注入氧化劑的方式，增加了氧化劑在引擎內部的滯留時間，並藉由渦旋流場提升氧化劑與燃料的混合效率以及燃料耗蝕率；同時降低引擎燃燒室工作壓力以研究其推進效能，並與較高工作壓力進行比較。本論文使用氮氣加壓供流系統驅動90%高濃度過氧化氫 (high-test peroxide) 進入觸媒床，並使用三氧化二鋁 (Al2O3) 為載體的三氧化二錳 (Mn2O3) 觸媒進行催化分解，隨後以渦漩注入的

方式注入燃燒腔，並與燃料聚丙烯（polypropylene, PP）進行燃燒，最後經由石墨鐘形噴嘴 (bell-shaped nozzle) 噴出燃燒腔後產生推力。實驗部分首先透過深度節流測試先針對原版腔壓40 barA引擎在低腔壓下的氧燃比 (O/F ratio)、特徵速度 (C*)、比衝值 (Isp) 等引擎性能進行研究，提供後續設計20 barA低腔壓引擎的依據，並整理出觸媒床等壓損以及燃燒室等流速的引擎設計轉換模型；同時使用CFD模擬驗證渦漩注射器於氧化劑全流量下 (425 g/s) 的壓損與等壓損轉換模型預測的數值接近 (~1.3 bar)。由腔壓20 barA 引擎的8秒hot-f

ire實驗結果顯示，由於推力係數 (CF) 在低腔壓引擎的理論值 (~1.4) 相較於腔壓40 barA引擎的推力係數理論值 (~1.5) 較低，因此腔壓20 barA引擎的海平面Isp相較於腔壓40 barA引擎的Isp 低了約13 s，但是兩組引擎具有相近的Isp效率 (~94%)，且長時間的24秒hot-fire測試顯示Isp效率會因長時間燃燒而提升至97%。此外，氧化劑流量皆線性正比於推力與腔壓，判定係數 (R2) 也高於99%，實現混合式火箭引擎推力控制的優異性能。透過燃料耗蝕率與氧通量之關係式可知，低腔壓引擎在相同氧化劑通量下 (100 kg/m2s) 較腔壓40 barA引擎降低

了約15%的燃料耗蝕率，因此引擎的燃料耗蝕率會受到腔體壓力轉換的影響而變動，本論文也針對此現象歸納出一校正方法以預測不同腔壓下的燃料耗蝕率，此校正後的關係式可提供未來不同腔壓引擎燃料長度設計上的準則。最後將雙氧水貯存瓶的上游氮氣加壓壓力從約58 barA降低至38 barA並進行8秒hot-fire測試，結果顯示仍能得到與過往測試相當接近的Isp效率 (~94%)，而此特性除了能讓雙氧水及氮氣貯存瓶擁有輕量化設計的可能性，搭配具流量控制的控制閥也有利於未來箭體朝向blowdown type型式的設計，因此雙氧水加壓桶槽上的氮氣調壓閥 (N2 pressure regulator valve)

將可省去，得以降低供流系統的重量，並增加箭體的酬載能力，對於未來箭體輕量化將是一大優勢。

Positive Regard in Psychotherapy: Rogers and Beyond

Barry A. Farber, PhD, is a Professor of Psychology and Education at Teachers College, Columbia University. Dr. Farber received his PhD from Yale University. Clinically, he has had training in behavioral, client-centered, and psychodynamically oriented psychotherapies. His research and scholarly int

erests are in the areas of psychotherapy process and outcome, the impact on the therapist of working in psychotherapy, the development of psychological-mindedness, and the way in which interpersonal disclosure is influenced by emerging technologies.

Previous research projects assessed the role of informal supervision among psychotherapy trainee

s, and client disclosure in correctional settings. Currently, she and her research team are exploring factors associated with therapists’ perceptions of positive regard, as well as clients’ experience of teletherapy since the onset of the COVID-19 pandemic.

基於深度學習與顏色特徵之行人辨識方法比較

為了解決RE: LAB的問題，作者陳文得 這樣論述：

行人辨識主要目的在於跨鏡頭人物的搜尋，也就是在不同鏡頭中找到同一個人。在深度學習被廣泛應用前，使用人物特徵直接進行比對是種常見方法，本文中研究的顏色特徵，便是屬於其中的一種方式。將顏色代表的數值劃分，使用KNN方式歸類各個顏色所在區域，以此為依據，取得人物圖像的顏色特徵，進行辨別。但由於鏡頭解析度不同、光線明暗不同，使得該人物即使衣著不變的情況下，顏色的特徵也會產生變化，進而影響比對的結果。所以，本文另一研究，採用深度學習方式，先對人物圖像進行水平切割，分別提取特徵，進行特徵訓練，並且加入動態對齊的演算，用來彌補人物姿態不一致的問題。最終實驗結果，優於直接特徵擷取的比對準確度相對提高。
