Encyclopedia of Planetary Landforms

為了解決paper.io 2的問題，作者Hargitai, Henrik (EDT)/ Kereszturi, Akos (EDT) 這樣論述：

Encyclopedia of Planetary Landforms contains a description and interpretation of all known planetary landforms that have been discovered on the planetary bodies in our Solar System. The content is separated into entries for each planetary landform. All entries are based on literature reviews, using

NASA/ESA/JAXA imagery and original general and thematic maps of the particular landform. Such a wide variety of landforms show how exotic these features could be from a terrestrial point of view, but at the same time emphasizes that the same processes will result in similar morphology, independent o

f its host planet. Illustrations show the generalized structure of each major landform type and is complete with a series of special maps published here for the first time. This organized classification of planetary landform types is not available in other books, and only partially covered in scatte

red papers. The most important places (landforms, named and unnamed) will be found in the main section as well as description and interpretation. This has never been done before. If necessary, these landforms will have an accompanying large-scale map. This will make it serve as a basic reference boo

k - not discussions of large metaconcepts but the stories of well-defined landform types and individual landforms, which is usually only found only in professional papers, one paper, one landform. So this knowledge is very much scattered around in the literature. Each landform will have a data secti

on with height (peaks and low points), diameter, age, data. USGS maps only have diameter data. How will it be used by planetary scientists? It will give a starting point to any landform he or she want to investigate. Previous works are thematic collections of knowledge (i.e., cratering in the Solar

System, volcanic processes, etc.), while this work will approach the subject from landform types and will go deeper by analyzing individual landforms and including maps and imagery. It will be as comprehensive as possible, not only describing the most popular targets but also the (now) lesser known

ones, which may be attractive for future analysis. As an example, suppose someone wants to compare valleys of the Moon and Mercury and Titan. He or she can use this work as a starting place to consult and will find imagery, examples, and the basic literature all collected in one section, including i

ndividual features, as well as where most valleys are found (global distribution). The maps will be printable and easy to handle, in contrast to large sheet paper maps. As for the content of the maps, they are not global maps but also not very detailed thematic geologic or topographic maps. They fal

l in between these extremes, which means that the researcher can understand the context but at the same time see all named features. These could serve as perfect reference maps for all planetary bodies. (Such maps are not available online.) The maps will be uniform in many of their cartographic char

acteristics, which gives the user a good opportunity to compare them, essential in any comparative planetology study (planets, moons, asteroids, etc.). Planetary bodies, where global topographic data is available, will be depicted in both topographic and photomaps and capable of being printed. The m

aps will contain official IAU names AND also informal geologic (and physiographic province) names that have never been put on maps (except for sketch maps), precisely because they are not official. However, since geologist use these names every day (and often complain about IAU's strict rules), we b

elieve that this make these maps much more useful for workers in the field. Maps are for helping to find places, and these names are very important in this respect. Geologic and physiographic names have never been collected in any form (list or map), not even by USGS Gazetteer, so this will be somet

hing brand new. Climatic data (climate diagrams) will be added to maps of Mars. The work will include a full, updated, alphabetical list of names, with links. By 2011, our Russian colleagues may be ready with their corrections of the USGS Gazetteer. If so, the work will include these as well. An Edi

torial Board will review different sections of the work.

基於特殊正交群SO(3)與積分型終端滑模的四旋翼無人機飛行控制器設計

為了解決paper.io 2的問題，作者江栢祥 這樣論述：

本論文主要研究四旋翼無人機的姿態和位置控制。首先將談論四旋翼無人機的基礎構造含硬體、韌體及飛行力學。接著將回顧其他常用姿態表示方法的優缺點。然後簡要介紹一種全域且唯一定義每一種姿態的特殊正交群SO(3)姿態表示法。基於這個姿態表示法，本文透過李亞普諾夫方程式與積分型終端滑動模式控制，設計姿態與位置控制器。除了保證無人機運動能力，滑動模式控制相較於比例積分微分控制器具有較好的強健性。最後並通過數值模擬與實際飛行實驗的結果對控制器進行有效性驗證。
