    High-resolution clean-sc

    No full text
    In this paper a high-resolution extension of CLEAN-SC is proposed: HR-CLEAN-SC. Where CLEAN-SC uses peak sources in “dirty maps” to define so-called source components, HR-CLEAN-SC takes advantage of the fact that source components can likewise be derived from points at some distance from the peak, as long as these “source markers” are on the main lobe of the Point Spread Function (PSF). This is very useful when sources are closely spaced together, such that their PSFs interfere. Then, alternative markers can be sought in which the relative influence by PSFs of other source positions is minimised. For those markers the source components better agree with the actual sources, which allows for better estimation of their locations and strengths. This paper outlines the theory needed to understand this approach and discusses applications to 2D and 3D microphone array simulations with closely spaced sources

    Yorkville Store Account Ledger - Accession 1743 - M832 (889)

    No full text
    This collection consists of pages of an account ledger from a Yorkville, SC store in November 9, 1827-December 10, 1827. The pages are believed to belong to the Hoke family at some time, and survived a fire. Each page lists the name of each customer, what they ordered, and the cost of item or items. This ledger would prove useful to researchers searching for Yorkville residents from the time period, what items were purchased by the residents in the first quarter of the 19th century and how much these items cost. Prominent names include: Edwards; Effler; Ellis; Erwin; Galbraith; Gilmore; Givens; Gordon; Harris; Hart; Herron; Hill; Hogge; Hood; Hoover; Hutchison; Jamison; Jeffrey; Latta; Lee; Lindley; Little; Love; Lowry; Martin; McCall; McKee; McLauchlin; Meek; Mellon; Melton; Miller; Mills; Moore; Owens; Perry; Riley; Robinson; Rogers; Rooker; Rowell; Sadler; Senn; ; Sitgreaves; Smith; Springs; Suggs; Sweeny; Tate; Thompson; Walker; Wallace; White; Williams; Witherspoon;https://digitalcommons.winthrop.edu/manuscriptcollection_findingaids/2774/thumbnail.jp

    Ca-modified Al–Mg–Sc alloy with high strength at elevated temperatures due to a hierarchical microstructure

    No full text
    Al-Mg alloys are normally prone to lose part of their yield and tensile strength at high temperatures due to insufficient thermal stability of the microstructure. Here, we present a Ca-modified Al–Mg–Sc alloy demonstrating high strength at elevated temperatures. The microstructure contains Al4Ca phases distributed as a network along the grain boundary and Al3(Sc,Zr) nano-particles dispersed within the grains. The microstructure evolution and age-hardening analysis indicate that the combination of an Al4Ca network and Sc-rich nano-particles leads to excellent thermal stability even upon aging at 300 °C. The tensile strength of the alloy for temperatures up to 250 °C is significantly improved by an aging treatment and is comparable with the commercial heat-resistant aluminum alloys, i.e., A356 and A319. At a high temperature of 300 °C, the tensile strength is superior to the above-mentioned commercial alloys, even more so when expressed as the specific strength due to the low density of Ca-modified Al–Mg–Sc alloy. The excellent high-temperature strength results from a synergistic effect of solid solution strengthening, grain boundary strengthening and nanoparticle order strengthening.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Novel Aerospace Material
