Online Discovery Planets

為了解決4k resolution的問題，作者 這樣論述：

ScienceWiz(R) Online Discovery Planets includes a digital flip book that provides a grand tour of the solar system.It integrates hands-on projects and celestial observations with breathtaking online materials.These include videos, simulations, Interactive 3D models and and deep dives into the cen

ters of the gas and ice giants. Watch an incredible 4K video of the actual surface of Mars, composited from data captured by NASA’s Mars rovers. This is our first ever high resolution view of another world! Listen to the profound and stunning video narration of Carl Sagan’s ＂Pale Blue Dot.＂ Take a d

eep dive into Saturn’s interior to watch gigantic diamond ice burgs float in a liquid diamond sea. Learn about the liquid oceans found to be buried underground on numerous moons and even beneath the frozen surface of the dwarf planet Pluto. Do some of these mineral rich oceans harbor life? The race

is on to find out. The word ＂planet＂ means wandering star. Five of these wandering stars are visible to the naked eye and were known to the ancients. These wandering stars, did not travel across the night sky in lock-step with all the other visible stars. Their paths were peculiar and unique. The an

cients did not know that these wandering stars were other worlds, but we do. Children and adults alike can now pinpoint these wandering stars themselves using the digital app provided. Just point the digital phone at the night sky in your neighborhood and you can eye-ball and distinguish each planet

from among the multitude of stars. Then point a pair of strong binoculars or a telescope to get a better view. Let the tour begin! PROJECTS AND ACTIVITIES INCLUDE: Locating the five planets with the naked eye: Mercury, Venus, Mars, Jupiter & Saturn using a digital app Making a basic telescope (

materials included).Taking a multi-dimensional tour of our Solar System onlineSpinning and exploring the surface features of each planet using 3D modelsWatching a 4K video of the surface of Mars and see what NASA’s rovers sawConstructing the planets to scaleDiscovering why Pluto was demoted to a dwa

rf planetDrawing circles and ellipses for yourself(The planets travel around the Sun in elliptical orbits.)Understand what makes an ellipse different from a circleLaying out the Solar System to scaleDiscover which planet could actually float in water.Learn about the asteroid beltsDiscover how most c

omets actually hide out in the Oort CloudDiscover amazing facts about the MOST studied meteorite on the planetMankind’s ever evolving knowledge of the Solar System is explored through videos, interactive play and simulations. Learn how human knowledge of the cycles (day-night, monthly and yearly) ha

ve been observed and recorded for thousands of years. These ongoing observations have led to our current understanding of the Solar System and our place among the stars. The kit includes a handle box for easy storage and transport, as well as materials for each project.

消費型攝影機生產製程改善之研究

為了解決4k resolution的問題，作者張家瑋 這樣論述：

現今消費型攝影機普及，逐漸使民眾對它的存在產生安全感，在產品普級化且無突破性功能的情況，伴隨而來的便是售價調降，由於售價較低的影響，若於批量生產皆耗廢大量工時及人力，便會壓縮到產品的銷售利潤，除尋找其它來源以降低半成品板及機構成本外，若能提昇組裝效益，即為營收最主要的方式。本研究針對消費型攝影機製程改善，藉由縮減製程工時以提升產品毛利，改善生產流程瓶頸，將瞬間膠固定鏡頭座製程，合併在調焦設備，整合調整焦距與鏡頭座固定，藉此達到縮減工時與提升製程能力，實驗結果顯示，在製程變動及膠體固定方式變更，實質降低每一個產品製程總工時，在製程改善後，產品品質也更穩定。

David Busch’s Canon EOS 5D Mark IV Guide to Digital SLR Photography

為了解決4k resolution的問題，作者Busch, David D. 這樣論述：

David Busch's Canon EOS 5D Mark IV Guide to Digital SLR Photography is your essential reference and guide book for Canon's ground-breaking 30.4 megapixel full frame dSLR. Canon's most versatile professional/enthusiast camera is adept at still photography, combining a high-resolution sensor with 7

fps continuous shooting, blazing fast autofocus, and excellent high-ISO performance. Those shooting video will be equally impressed with its 4K Ultra High Definition movie mode and Dual Pixel AF that allows continuous autofocus even when capturing video. Touch screen access to features, a 150,000-p

ixel RGB+infrared exposure sensor, and built-in Wi-Fi and GPS add to the 5D Mark IV's appeal. With this book in hand, you will discover all the capabilities of the Canon EOS 5D Mark IV as you explore the world of digital photography, develop your creativity, and capture the best photographs you've e

ver taken. Filled with detailed how-to steps and full-color illustrations, David Busch's Canon EOS 5D Mark IV Guide to Digital SLR Photography describes every feature of this sophisticated camera in depth, from taking your first photos through advanced details of setup, exposure, lens selection, lig

hting, and more. It relates each feature to specific photographic techniques and situations. Also included is the handy camera "roadmap," an easy-to-use visual guide to the Mark IV's features and controls. Learn when to use every option and, more importantly, when not to use them, by following the a

uthor's recommended settings for every menu entry. With best-selling photographer and mentor David Busch as your guide, you'll quickly have full creative mastery of your camera's capabilities, whether you're shooting on the job, taking pictures as an advanced enthusiast exploring photography for the

first time, or are just out for fun. Start building your knowledge and confidence, while bringing your vision to light with the Canon 5D Mark IV.

量化卷積神經網路之視訊注視點超解析度成像處理器設計

為了解決4k resolution的問題，作者黃成漢 這樣論述：

邊緣運算(edge computing)是將人工智慧應用到日常生活很重要的環節，用途包含醫療診斷、穿戴裝置、自駕車等等。相對於將資料傳輸到遠端伺服器處理的雲端計算，邊緣計算少了網路傳輸的延遲，更適合在需要即時處理的應用上。量化可將浮點數(floating-point)神經網路模型轉為bit數小的定點數(fixed-point)模型，可以提升運算效率，並減少存儲空間。而低功耗的藍芽模組(Bluetooth Low Energy, BLE)，成為邊緣裝置傳輸資料的主流。本論文中，我們首先提出了一套方法搜索定點數模型位元寬度(bit-width)以及剪裁值(clipping value)，降低量化

時造成的精確度損失。沒有引介其他參數和額外訓練過程，甚至可以在平均4 bit底下得到極佳的結果，微調量化後的模型權重後還可以達到相同甚至更高的精確度。為了使視訊傳輸達到藍芽低功耗(BLE)的低傳輸率，我們降低傳輸時的解析度，並使用注視點超解析度影片成像技術(foveated video super-resolution)，於邊緣裝置還原回高解析度。本論文提出一個基於卷積神經網路(CNN)的FVSR處理器架構，結合特徵暫存(feature buffer)，就我們所知，本論文為第一個使用空間與時域的特徵的設計。利用層融合(layer fusion)架構降低對DRAM的存儲次數，減少耗能以及存儲的延

遲時間。相比傳統算法，量化後的FVSR模型更能復原細節輪廓。我們使用Xilinx Ultrascale+ ZCU-106現場可程式化邏輯閘陣列(FPGA)驗證系統，使用了178 K個查找表(LUT)與231 K個正反器(flip-flop)，以及265 Kb區塊隨機存取記憶體(Block RAM)。在150 MHz的工作頻率下，本加速器可以15 FPS速率輸出Full HD的影片。
