My hearts a thumpin’, bumpin’, jumpin’, I feel like dancin’! I feel like prancin’! Just chock full of joy. (Boy!) I can’t keep from watching the clock; At the door seems I hear a knock; All on fire inside an out, I just want to shout. Can’t you guess? Can’t you guess, Why I’m stuffed with happiness, I’ll tell you: [Chorus] Somebody’s coming to town (from Dixie) Someone with two eyes of brown (from Dixie) Somebody always is going to stay, never go ‘way Hip, Hip, Hooray! Somebody wrote me a note; (from Dixie) This is what somebody wrote: “I’m coming; I’m coming; meet me when the sun goes down.” Oh! Lawdy, be good to that railroad somebody’s coming to town [Verse 2] Ten after seven, I’ll be in heaven, Somebody’ll be there; see there me there; Such loving blisses, such hugs and kisses, Right there on the spot. (What?) Good, kind train please stay on the track, If you smash my poor heart’ll crack, Good kind engine, please hear my call, Get here quick, that’s all, Don’t be late, Don’t be late For your freight I just can’t wait, I’m nervous [Chorus

    Simulation Study of TenTen: A new Multi-TeV IACT array

    Full text link
    TenTen is a proposed array of Imaging Atmospheric Cherenkov Telescopes (IACT) optimized for the gamma ray energy regime of 10 TeV to 100 TeV, but with a threshold of ~1 to a few TeV. It will offer a collecting area of 10 km2 above energies of 10 TeV. In the initial phase, a cell of 3 to 5 modest-sized telescopes, each with 10-30 m2 mirror area, is suggested for an Australian site. A possible expansion of the array could comprise many such cells. Here we present work on configuration and technical issues from our simulation studies of the array. Working topics include array layout, telescope size and optics, camera field of view, telescope trigger system, electronics, and site surveys.Comment: 4 pages, 7 figures, submitted to Proceedings of the ICRC 2007, pdf forma

    TenTen: A New Array of Multi-TeV Imaging Cherenkov Telescopes

    Get PDF
    The exciting results from H.E.S.S. point to a new population of gamma-ray sources at energies E > 10 TeV, paving the way for future studies and new discoveries in the multi-TeV energy range. Connected with these energies is the search for sources of PeV cosmic-rays (CRs) and the study of multi-TeV gamma-ray production in a growing number of astrophysical environments. TenTen is a proposed stereoscopic array (with a suggested site in Australia) of modest-sized (10 to 30m^2) Cherenkov imaging telescopes with a wide field of view (8 to 10deg diameter) optimised for the E~10 to 100 TeV range. TenTen will achieve an effective area of ~10 km^2 at energies above 10 TeV. We outline here the motivation for TenTen and summarise key performance parameters.Comment: 4 pages, 2 figures, proceedings of the 30th ICRC, Merida, Mexico, 200

    Timing analysis techniques at large core distances for multi-TeV gamma ray astronomy

    Full text link
    We present an analysis technique that uses the timing information of Cherenkov images from extensive air showers (EAS). Our emphasis is on distant, or large core distance gamma-ray induced showers at multi-TeV energies. Specifically, combining pixel timing information with an improved direction reconstruction algorithm, leads to improvements in angular and core resolution as large as ~40% and ~30%, respectively, when compared with the same algorithm without the use of timing. Above 10 TeV, this results in an angular resolution approaching 0.05 degrees, together with a core resolution better than ~15 m. The off-axis post-cut gamma-ray acceptance is energy dependent and its full width at half maximum ranges from 4 degrees to 8 degrees. For shower directions that are up to ~6 degrees off-axis, the angular resolution achieved by using timing information is comparable, around 100 TeV, to the on-axis angular resolution. The telescope specifications and layout we describe here are geared towards energies above 10 TeV. However, the methods can in principle be applied to other energies, given suitable telescope parameters. The 5-telescope cell investigated in this study could initially pave the way for a larger array of sparsely spaced telescopes in an effort to push the collection area to >10 km2. These results highlight the potential of a `sparse array' approach in effectively opening up the energy range above 10 TeV.Comment: Published in Astroparticle Physic

    [Verse 1] Oh! oh! Hear the bells a ringing! Oh! oh! hear the organ singing! Are you ready? It’s our wedding day, Hooray! Oh! oh! see the folks are waiting! Take my hand, and, When the knot it tied, Standing side by side, We will start for Happy land. [Chorus] “Lets go honey spooning, Honey! In the Loving Land we’ll wander, hand in hand, Oh! Oh! Oh! Lets go honey mooning Honey! Say, won’t that be grand? Just you Listen to this: We’ll have all kinds of bliss, For we’ll hug and we’ll kiss, Not a thing will we miss! Come along! Come along to Honey moon Land” [Verse 2]Oh! oh! how my heart is humming! Oh! oh! happy days are coming! Hear that music playing soft and low, lets go! Oh! oh! Preacher is a calling; Time is here, dear, In a little while, Walking down the aisle, I will whisper in your ear: [Chorus] *Note: hand written lyrics have been added above the staf

    Proof Theory and Ordered Groups

    Full text link
    Ordering theorems, characterizing when partial orders of a group extend to total orders, are used to generate hypersequent calculi for varieties of lattice-ordered groups (l-groups). These calculi are then used to provide new proofs of theorems arising in the theory of ordered groups. More precisely: an analytic calculus for abelian l-groups is generated using an ordering theorem for abelian groups; a calculus is generated for l-groups and new decidability proofs are obtained for the equational theory of this variety and extending finite subsets of free groups to right orders; and a calculus for representable l-groups is generated and a new proof is obtained that free groups are orderable

    Influence of Land Cover and Soil Moisture based Brown Ocean Effect on an Extreme Rainfall Event from a Louisiana Gulf Coast Tropical System

    Get PDF
    Extreme flooding over southern Louisiana in mid-August of 2016 resulted from an unusual tropical low that formed and intensified over land. We used numerical experiments to highlight the role of the ‘Brown Ocean’ effect (where saturated soils function similar to a warm ocean surface) on intensification and it’s modulation by land cover change. A numerical modeling experiment that successfully captured the flood event (control) was modified to alter moisture availability by converting wetlands to open water, wet croplands, and dry croplands. Storm evolution in the control experiment with wet antecedent soils most resembles tropical lows that form and intensify over oceans. Irrespective of soil moisture conditions, conversion of wetlands to croplands reduced storm intensity, and also, nonsaturated soils reduced rain by 20% and caused shorter durations of high intensity wind conditions. Developing agricultural croplands and more so restoring wetlands and not converting them into open water can impede intensification of tropical systems that affect the area
