基於網路化監控系統於發光二極體之功率控制及其數據化分析的時間序列設計模式
為了解決javascript number 的問題,作者蒲里亞 這樣論述:
發光二極體(LEDs)的技術品是有節能效益、照度優、效能優、長壽命優,而被認為是許多光源應用中最佳來源之照明。然而影響LEDs的最大問題所在就是其壽命週期,包括LEDs的光效能下降或突然失效,而不穩定的正向電壓、不足的限制電流和高溫會導致LEDs光衰退的發生。所以能夠即時監控LEDs參數物理變化,以及在特定條件之下控制LEDs的功率及是減少光衰退的方法之一。本論文研究是基於應用Web的網路便利性方式來構建時間序列之參數監控化系統和一個LEDs電源控制系統,以樹莓派(Raspberry Pi)和ESP32作為系統的主要設備。為了讓系統介面給使用者方便來應用,建構兩個用戶界面(UI),以及參數數
據存取方式和方便管理時間序列之資料庫數據,作為測量物理變化和執行動作由ESP32和ESP8266處理,並將傳輸和執行設備鏈結到系統,而蒐集數據與存取並藉由無線網路鏈結傳遞到Raspberry Pi,以完成更好的移動性與遠程使用MQTT發布/訂閱消息連接協議。因有Web的網路應用程序於即時監測和控制,任何設備可透過Web網路瀏覽器查詢。監控UI使用TIG (Telegraf, InfluxDB, and Grafana)堆疊技術,這是一個平臺的字體縮寫,對時間序列之參數與資料庫數據進行擷取、儲存、繪圖和警示。另外對電源控制UI是基於Web網路之應用方式來做使用HTML語言與Javascript構
建之程式,透過改變LEDs功率進行測試與實驗調整。實驗發現LEDs的驅動器能夠對LEDs使用者提供從0 V到22 V的電壓範圍設定和0 mA 到2,000 mA的電流範圍設定。
ECMAScript關鍵30天:ES5到ESNext精準進擊JS語法與核心(iT邦幫忙鐵人賽系列書)
![](/images/books_new/001/090/07/0010907980.webp)
為了解決javascript number 的問題,作者YuriTsai 這樣論述:
無論你是前端還是後端,點滿 Modern Web技能樹的第一步,就是徹底認識 ECMAScript! 本書內容改編自第12屆 iT 邦幫忙鐵人賽-Modern Web 組佳作系列文章《從 ES 到 ESNext - 30天輕鬆掌握ECMAScript》。作者以推動 JavaScript 發展的官方標準-ECMAScript 作為切入主題,從語法結構來認識 JavaScript。 本書一開始,以循序漸進、深入淺出的介紹方式,帶領讀者熟悉重要概念和基本組成,並且讓讀者在閱讀時,清楚了解有哪些相關的章節內容,藉此達到融會貫通的效果。 語法介紹部分,則是彙整參數說明、重要特性、環
境支援度等表格,加上生動的圖說和範例程式,讓讀者全面掌握語法的起手式。 作者希望本書可以成為初學者的最佳入門書,也能幫助有實務經驗的開發者在工作能發揮影響力,成為最得力的左右手! 本書特色 核心概念 一次掌握 使用圖解加上直白的敘述,深入淺出函式、物件、原型、執行環境、this 等等讓初學者頭痛的重要機制。就算是有經驗的開發者,看完也能有新的收穫! 語法分類 特性統整 根據標準內建物件的種類和常用性規劃章節,並且依情境分類重要語法,一目瞭然的圖表和程式碼,發揮工具書的最大價值! ES2022 未出先看 每年埋頭苦追新釋出的標準,已經覺得累了嗎?本書透過清楚
的中文敘述,並且搭配簡單的程式範例,快速掌握開發新潮流!
基於運行環境事件之程式行為萃取及其應用
為了解決javascript number 的問題,作者李泓暐 這樣論述:
由於電腦科技逐漸在各處都可見其身影和日益複雜的電腦系統,了解那些在電腦系統中的程式行為無可避免地成為一個重要的議題。鑒於在沒有程式輸入下僅靠程式原始碼來分析程式是有困難的,又或者靠程式機器碼,但即使是一個簡單程式,其機器碼也相當複雜而難以分析,本篇論文轉而藉由觀測那些在程序(運行中的程式)所觸發的事件來分析程式行為。雖然那些事件自然地蘊含了許多關於該程式的資訊,但相對的,種類繁多的事件語意和格式仰賴於執行環境,若要有較好的偵測效率或效果,將使得觀測或分析時期的優化需要大量的專家知識。除此之外,一次大量的事件或是快速的事件生成速率(尤其是在觀測低階事件)皆會限制其線上應用。本篇論文將提出兩個程
式行為模型涵蓋了三種不同面向的程式行為,這些行為在現今環境都有非常廣泛的應用。流域模型(Watershed model)針對程式計算量和並行性,而輪廓模型(Profile model)針對程式功能性,而且這些模型的輸入能夠非常簡單地從真實系統事件中進行對應,不需要大量專家知識以及完整的事件語意。為了證明這些模型的實務價值,本篇論文實作了兩個雛型系統分別基於其中一個模型在效能分析和安全應用上,並且進行充分地評估。
