The success of the Internet of Things and rich cloud services have helped create the need for edge computing, in which data processing occurs in part at the network edge, rather than completely in the cloud. In Edge Computing: A Primer the vision and definition of Edge computing is introduced, as well as several key techniques that enable Edge computing. Then, four applications that benefit from Edge computing are presented as case studies, ranging from smart homes and public safety to medical services, followed by a discussion of several open challenges and opportunities in Edge computing. Finally, several key tools for edge computing such as virtualization and resource management are explained.

This book focuses on the crucial theme of modern test development and analysis, specifically focusing on bridging the gap between theoretical frameworks and practical applications. This resource offers a practical and detailed exploration of psychometric principles, encompassing both Classical Test Theory (CTT)-based item analysis and Item Response Theory (IRT), specifically focusing on the One parameter model (Rasch model) for test equating. By considering CTT) and the more sophisticated Rasch model, the book provides a comprehensive pathway to enhanced measurement accuracy and efficiency in the human sciences It aims to empower readers with the tools and knowledge necessary to navigate the complexities of test equating, item bank creation, and the implementation of Computerized Adaptive Testing (CAT). It provides historical context for these methodologies and outlines prospects for Rasch research, emphasizing the importance of establishing a common scale for measuring ability. A significant contribution is the introduction of Rasch-GZ, a cutting-edge software developed during the COVID-19 pandemic that incorporates AI-driven assistance and bilingual support, potentially streamlining the calibration process of items within an item bank. The book thoroughly reviews fundamental concepts such as item difficulty and discrimination, ensuring readers grasp the theoretical underpinnings of both CTT and IRT. It delves into various test equating techniques, including Common Item Linking and potentially Common Subject Linking, crucial for maintaining invariance across different test forms within a Standardized Examination. Real-world examples with detailed interpretations serve as a step-by-step guide to these procedures, often relying on anchor items. While implicitly addressing the concept of the norm in the context of standardized examination interpretation, the resource primarily focuses on the application of psychometric software. Access to the student version of Rasch-GZ is provided through code, alongside supplementary video tutorials, facilitating hands-on learning and software mastery. This book could be used by practitioners in the fields of applied linguistics, applied psychology, language testing, education management, and researchers working on language testing methods.

文学创作需要时间、执着和锲而不舍的耐力。创作是一种不屈不饶、尝尽甜酸苦辣的经历。《创作回顾》所记录的是作者张泉先生在1995-2021年间断断续续业余创作的经历。除了回顾作者创作小说、散文、传记、回忆录的同时还记录了部分作者所创作的美篇作品。

"伸出你的手，给世界奉献一点爱，那么，我们将有一片爱的天空。 伸出你的手，用关爱温暖一颗心，那么，每个人心中都充满了爱。 伸出你的手，即使是微不足道的一点爱， 也要带给别人关怀......让我们伸出蒙恩的手传递上帝的爱，因为神先爱我们。"愿《伸出蒙恩的手》成为更多人的祝福，保住更多的心灵家园！

林慰楨教授早年考取第七屆中英庚款，一九四零年與錢偉長、郭永懷、林家翹等同船前往加拿大留學。誰也沒有料想到，第七屆中英庚款奬學金化學專業得主林慰楨在麥基爾大學所選的博士專業名義上是化學，而實際是礦冶工程(Mining and Metallurgical Engineering)。誰也不會猜想到此時此刻對林慰楨「真正有價值的」東西並不是「學位」而是盡快地掌握如何從含鋁質高的礦石中提煉鋁、如何將鋁轉化成用於製造飛機的那種質輕而堅固的鋁合金(duralumin)。 他決意不惜一切代價，把西方從礦石中提煉鋁轉化成鋁合金的最先進的理論、技術和程序學到手，用鋁合金製造出自己的戰鬥機來扭轉抗戰因沒有制空權而造成的被動戰局。一九四二年獲得博士學位后，林慰楨參與、指導、設計了多項冶金提煉研製工作，經過多年不懈的實驗努力，終於研製出一種浸出壓力冶金提煉鎳的新方法並將此法推廣、應用到提煉其它稀有金屬種類。他所參與的諸多發明專利一直被世界礦業冶金業推崇，並被世界上（包括中國）許多礦業冶金業受權採納、應用於幾乎所有回收稀有金屬提煉程序中。

轉眼間，信主二十九個春秋過去了。對於一個有限的人生，二十九個春秋實為不短的日子。但在兩千多年基督教信仰史的長河中它卻是短暫的瞬息。就像驅車奔馳在高速公路所看到的掠影一樣，即便是一瞬間、一霎那，那些盡收眼底的人物、景象，有的會刻骨銘心、終生難忘。時間、歷史的長河就是由這無數短暫的瞬間、眨眼的霎那連接而成。絢麗多彩的全景是由這無數一閃而過的掠影繪製組合。 在信主二十九個寒暑春秋里，作者所遇到遇到了很多為神國侍奉的僕人。他們中有不善言語的，做事說話令人費解的，含辛茹苦、忍辱負重的，不由自主、身不由己的，身有殘疾的，也有英年早逝的。但在侍奉中，不善言語的，卻能見證出費盡口舌也講不清的信仰、福音和《聖經》。英年早逝的，在她短暫的一生裡迸發出永恆的生命火花。 他們充滿活力的見證來自於他們獨特的國度侍奉觀。他們侍奉的是神不是人；侍奉的是那位"使我們和睦，將兩下合而為一，拆毀了中間隔斷牆"的神。國度的侍奉沒有教會內外之分、宗派之別。僕人不分彼此、同舟共濟、異曲同工。國度以外的巴別塔再高、裝飾再華麗，他們從不偏心離異。定意仰望為信心創始成終的耶穌，存心忍耐、奔那擺在前頭的路程。侍奉中被人誤會、歧視、排擠、讒言、惡語，他們繼續侍奉。因為他們堅信國度的冠冕在神不在人。 "雖然無花果樹不發旺，葡萄樹不結果，橄欖樹也不效力，田地不出糧食，圈中絕了羊，棚內也沒有牛", 他們仍舊侍奉。因為他們知道所信的是誰，並且也深信祂能保全他們所託付祂的，直到那日。國度的侍奉註重的是持守真理，言行一致，表裡如一。沒有高言大智、華麗的辭藻。沒有高低之分、貴賤之別。 兩千多年基督教信仰經久不衰、百折不饒，正是因為千千萬萬個像這樣的神國僕人，他們不分彼此、同心合一地完成主所託付的大使命。兩千年來他們為國度辛勤耕耘、兢兢業業、前赴後繼、鞠躬盡瘁。他們的侍奉跨越種族、文化、傳統；跨越教會、社區、國界；他們的腳踪遍及全地。

This is a collection of 12 short stories written by Chinese author Quan Zhang. The first story, titled "Colonel Ma's Father," was previously published in the 1996 winter issue of Folio: A literary Journal. In the second story titled "The balcony", the author used the stream of consciousness and disrupted time sequence that William Faulkner had used so well in his novel, The Sound and the Fury. As in Faulkner's novel, the protagonist is mentally challenged. From his place of imprisonment on the balcony of his family's apartment, in a privileged residential compound, he watches the unfolding of some of the madness of the Cultural Revolution. The author then wrote a half dozen more stories including "The Birds & Bees in Beijing," "The Bridge," "Chimeras," "Chicken Blood Therapy," "The Jaundice Ward" and "Trojan Rooster," all of which were accepted and published in various literary journals.

《离乡人》通过描写修建一所公馆，向读者展示了三位生活在美国的大陆人的过去和现在的不同经历。韩江，"文革"时期的红卫兵，刚获得美国历史博士学位，正面临在美国找工作的难题。好友姚陆生需要一位暖水工助手，韩江欣然同意去做他的助手。姚陆生在国内曾因家庭出身问题倍受歧视、虐待，后逃离大陆，定居美国。巴里黄曾是一个"文革"起家、后又叛逃的共产党干部。来美后，他四处投机钻营，很快就成了房地产主。人生的机运把这三位不同背景、不同经历的大陆人聚集在美国。韩江和姚陆生很快发现他们被攥在横行霸道的巴里黄的手里，重复体验到他们各自在大陆的经历。

此书为编著，转载和摘录的文章和评论大多取自世界媒体和联网论坛。所记载的大多是笔者这些年在各种网群中所浏览到的有关探讨大陆变革以来的文章和评论。许多百思不得其解的事情、事件，随着时间的推移，尘埃落定，笔者才悟出苏轼在《题西林壁》中所写那句名言："横看成岭侧成峰，远近高低各不同。不识庐山真面目, 只缘身在此山中。"
