Implementing Ios and Macos Documents With the Files App: Managing Files and Ensuring Compatibility

為了解決Location png的問題，作者Feiler, Jesse 這樣論述：

Rise above the basics of Xcode app development to implement tools like Share buttons and activity view controllers to share document content including parts of documents with other users and with other devices. This book fills the gap so that developers with even a fundamental knowledge of iOS and S

wift can implement document creation, saving, and sharing in their apps.Since the launch of iPhone in 2007, users and developers have struggled with the fact that the file system is hidden. Fortunately the Files app in iOS 11 now offers this feature and it is supported by Apple apps such as Numbers,

Pages, and Keynote as well as by the few third-party apps that support documents. By using the standard formats described in this book, you can make your app's data shareable to and from other apps like Numbers, Pages, and Word. Files also provides an interface to tools such as Dropbox and iCloud s

o that users can open and modify documents in them. If you combine standard formats such as .doc, .docx, .jpeg, and .jpg with Dropbox and eMail, you have a simple way to implement and use cross-platform sharing to Macs, PCs, and Android devices. Implementing iOS and macOS Documents with the Files Ap

p provides the combination of skills developers need to build these types of apps--working with files and constructing documents. What You'll LearnAdd Document Support to Your Apps Share your documents with iCloud and Apple IDs across your Mac and iOS devices Use standard formats from .doc, .docx, .

png, and .jpeg both for input and outputManage and organize documentsWho This Book Is ForDevelopers with a basic knowledge of app development and Swift. You should already know how to use Xcode to create an app. Knowledge of basic Swift syntax is recommended. The book can also be a useful overview a

nd guide to managers who are trying to decide how to convert legacy document-based systems to apps. Jesse Feiler is a developer, consultant, and author specializing in database technologies and location-based apps. Jesse’s apps include NP Risk, Minutes Machine, Utility Smart, Cyber Continuity, and

基於UWB人員定位技術提升智慧管理效能之研究

為了解決Location png的問題，作者葉珉辰 這樣論述：

隨著第四次工業革命後，許多領域與科技開始結合，人工智慧、5G開始進入到社會中，加上無線通信技術及網際快速發展，以及現在不斷開發室內空間，現今社會中迫切需要高精度和實質性的室內定位服務，如車間材料配送、智慧醫療、智慧家居、大賣場甚至是目前受歡迎的智慧工廠，所有都是室內空間，基於上述的需求，因此產生許多定位技術，從最一開始全球定位系統(GPS, Global Positioning System)，雖然不能應用在室內環境，但也為定位技術走出了第一步，之後陸續出現Wi-Fi、RFID(無線射頻)、藍牙、超聲波、紅外線以及ZigBee室內定位。這些定位技術都有各自的優勢，雖然可以滿足許多場域，但依照

目前情況下來看，現行的技術，只能應用在較簡單的場域，應用在較複雜的場域，因為穿透性，以及設備的干擾會造成定位精凖度偏差，無法實現高精度定位。超寬頻(UWB, Ultra-wideband)定位的出現，通過其獨特的脈衝訊號傳送加上由於頻寬較大，因此擁有較好的測距能力，定位精凖度可達公分等級，及具有一定的穿透能力，因此應用在智慧工廠上，是最好的選擇，最終我們也會透過測試不同場域，找出最適合安裝定位基站及放置定位卡片的位置，透過數據回傳至終端伺服器，可以第一時間觀察人員行為，是否有在安全場域，也會調整卡爾曼濾波器(Kalman filter)，過濾掉一些突然干擾的訊號，使連續座標出現在地圖上更加順暢

，通過反覆測試尋找最適合的數值，最終透過UWB定位技術提升智慧工廠的產能及效率。本論文，藉由比較人員放置定位卡片及基站設置的位置，經過一系列的嘗試，最終尋找出最適合智慧工廠室內定位的解決方案。關鍵字: 智慧工廠、室內定位系統、UWB、三角測量法
