Galaxies in the Local Volume

為了解決LV Germany的問題，作者Koribalski, B. s. (EDT)/ Jerjen, H. (EDT) 這樣論述：

The Local Volume' (ie, the sphere of radius 10 Mpc centered on the Local Group) is known to contain at least 500 known galaxies, many of which congregate in well-known groups like the Local Group, the relatively loose Sculptor Group, and the more compact Centaurus A group. Accurate distances are no

w available for the majority of these nearby galaxies, allowing us to visualise the Local Volume in 3D, study the local Hubble flow and its dispersion, the (baryonic) Tully-Fisher relation, the local star formation density, etc. Individual galaxies in the Local Volume can be studied in amazing detai

l across a large range of wavelengths (some stunning examples are compiled in the Multiwavelength Astronomy pages).The first catalog of galaxies within 10 Mpc was compiled by Kraan-Korteweg & Tammann (1979); it contained 179 galaxies. Following numerous updates, the latest Catalog of Neighboring Ga

laxies' was presented by Karachentsev et al. (2004); it contains 451 galaxies. They find that about 85% of the LV population are dwarf galaxies which contribute approx. 4% to the local optical luminosity density and roughly 10-15% to the local HI mass density. For the majority of galaxies within 8 M

pc we currently have quite reliable, independent distance estimates either from the luminosity of Cepheids, the tip of the red giant branch (TRGB), or surface brightness fluctuations (SBF).Several large surveys of nearby galaxies have recently been carried out or are in progress. E.g., The Westerbo

rk observations of neutral Hydrogen in Irregular and SPiral galaxies' (WHISP, Swaters et al. 2002), which is based on the Uppsala General Catalogue of Galaxies (UGC; Nielson 1973), provides HI distributions and velocity fields of about 200 gas-rich galaxies with declinations larger than +20 degrees

and velocities less than 2000 km/s. This is complemented by The Ha Galaxy Survey' (HaGS; James et al. 2004), also based on the UGC, which provides star formation parameters for a large number of mostly northern galaxies. The HI Nearby Galaxy Survey' (THINGS; Walter, Brinks, de Blok et al. 2004), w

hich provides high-resolution HI imaging of initially 36 galaxies with declinations larger than -30 degrees, has just been completed at the Very Large Array (VLA). The THINGS sample is targeting galaxies from The Spitzer Nearby Galaxies Survey' (SINGS, Kennicutt et al. 2003), a comprehensive infrar

ed imaging and spectroscopic survey of 75 nearby galaxies with distances less than 30 Mpc, as well as key objects from the Spitzer GTO list. SINGS is supplemented by high-resolution studies at many other wavelengths covering the entire spectrum from X-ray to radio. Another multi-wavelength study is

The Survey for Ionization in Neutral Gas Galaxies' (SINGG, Meurer et al. 2006, Hanish et al. 2006), the largest star formation survey of an HI-selected sample (based on The HI Parkes All-Sky Survey', HIPASS) and its sister surveys SUNGG and SONGG, based on GALEX ultraviolet and Spitzer infrared ob

servations, respectively. Surveys of nearby galaxies currently underway in Australia include The Galactic All Sky Survey' (GASS), obtained with the Parkes 64-m telescope, The Local Volume HI Survey' (LVHIS), obtained with the Australia Telescope Compact Array (ATCA), and the Local Sphere of Influ

ence H-band survey' (LSI), obtained with the Anglo-Australian Telescope (AAT).Given the many recent advances in our understanding of the star formation and ISM composition of nearby galaxies and more generally in the field of Near-Field Cosmology', which are mostly based on the large amounts and su

perb quality of new ground- and space-based multi-wavelength data, it is timely to hold a conference on the subject and review the Local Volume by combining observations, simulations and theoretical developments. We hope to provide a vibrant forum for presentations and discussions accross a broad ra

nge of astrophysical topics, including what may be possible with future facilities such as the Atacama Large Millimeter Array (ALMA), and the international Square Kilometre Array (SKA). B.S. Koribalski (Physics Diploma and PhD from the University of Bonn, Germany; now Senior Research Scientist at

無氟超疏水高分子複合材料製備及其在高效能油水分離與乳化液分離之應用

為了解決LV Germany的問題，作者Dula Daksa Ejeta 這樣論述：

在工業上以及我們的日常生活中常會產生許多含油廢水，這些含油廢水的排放以及海面上的漏油汙染皆會對自然環境造成嚴重的影響。此外，在石油化學工業中，油品中的少量水分也會對其造成許多問題，這些問題需耗費許多資源來解決。因此，開發具有高通量、低耗能、操作簡易、低成本、可量產之乳化劑穩定油包水乳化液處理材料是一個重要的課題。在本研究分為三個部分，我們製備三種具有不含氟、價格低廉之超疏水高分子複合材料。第一個研究中，我們利用聚（4-乙基苯酚）與1,3-phenylene bisoxazoline改質市售棉花，製備具有超疏水與超親油特性之高分子複合材料。此材料經壓縮後可應用於油包水乳化液分離，在重力過濾與加

壓過濾下可分別展現10,400 L m-2 h-1 (gravity-driven) and 867,500 L m-2 h-1 bar-1 (0.1 bar)的高通量。在第二個研究中，我們以主練型聚氧代氮代苯并環己烷改質美耐皿海綿製備超疏水材料，此材料展現極佳的吸油特性(最多可吸附本身重量170倍之油汙)，壓縮後可應用於油包水乳化液分離，在重力過濾與加壓過濾下可分別展現13,900 L m-2 h-1 (gravity-driven) and 1,353,000 L m-2 h-1 bar-1 (0.025 bar)的高通量。最後一個研究中，我們利用酚醛樹脂與氧代氮代苯并環己烷改質市售棉花，

製備超疏水高分子複合材料。此材料可應用於油水混和液分離，展現1.8x105 L m-2 h-1的高通量。壓縮後可應用於油包水乳化液分離，展現1.6x106 L m-2 h-1 bar-1 (0.025 bar)的高通量。以上的乳化液分離實驗中，濾液的油純度皆高於99.95 wt%，分離效果良好。我們的超疏水高分子複合材料因其高通量、高分離效率、低成本的製備方法皆說明它們在現實應用中具有巨大的潛力。

應用混合式濾波器於電力品質之綜合補償

為了解決LV Germany的問題，作者曹仁瑋 這樣論述：

隨著國際與國內經濟高速發展，帶動電力需求不斷攀升，加上電源側分散型電源的深度開發及用電側高效率可控設備的性能追求，愈來愈多單相/三相及間歇性電源/劇烈變動負載併入系統運轉，使電力品質的挑戰日益高漲。本文主要檢視用戶端因負載運轉特性而導致之電力品質問題，包括三相不平衡、諧波汙染、功率因數及電壓閃爍等，其成因、影響、相關管制標準及改善方法亦一併探討。本論文提出以靜態虛功補償器搭配主動式濾波器之混合式濾波器架構，用於改善負載側電力品質之綜合補償策略，以維持用電設備可靠且穩定的電力系統供電品質。其中，靜態虛功補償器係以對稱分量法作為無效功率控制之基礎；主動式濾波器則應用瞬時無效功率法即時計算補償電流

命令。此外，提出結合對稱分量法與瞬時無效功率法，並應用選擇性補償策略作為本文開發電力品質綜合補償系統之依據。本論文使用Matlab/Simulink 建置混合式濾波器架構及以Matlab/App Designer開發電力品質綜合補償系統，在多種不同模擬情境下驗證，結果顯示本論文所提之方法皆可達成所預期的電力品質改善目標。
