Notes: A fast production scheduling system, the very fast scheduler (VFS), hasbeen developed by the authors. It creates a capacity constrainedproduction schedule within one minute of elapsed time for problems of asize encountered in industry. The quality of the schedules is comparablewith the best alternative heuristic scheduling techniques. The speed ofthe scheduler is such that it can be used on a real-time basis to plancapacity, adjust priorities and other parameters and derive newschedules.

Notes: The seminal work of Nijboer and De Wette [Physica 23, 309 (1957)] enables the calculation of lattice sums of spherical harmonics, but has long been overlooked. In this article, their central result is recast in a simplified form suitable for modern multipole algorithms that employ the solid harmonics. This formulation makes possible the imposition of periodic boundary conditions within modern versions of the fast multipole method, and other fast N-body methods. The distinction between the extrinsic values obtained with the lattice sums M of the multipole interaction tensors, and the intrinsic values associated with Taylor's expansion of the Ewald formulas, is made. The central constants, M, are computed to 32 digit accuracy using extended precision arithmetic. Timings and corresponding errors obtained with a periodic version of the fast multipole method are presented for particle numbers spanning [103,106], and a range of expansion orders. A qualitative comparison is made between the present implementation, other periodic versions of the fast multipole method, and fast Ewald methods. © 1997 American Institute of Physics.

Transient convective uplift of an ancient buried landscape (2011)
Nature Publishing Group (NPG)

Description: Transient convective uplift of an ancient buried landscape Nature Geoscience 4, 562 (2011). doi:10.1038/ngeo1191 Authors: Ross A. Hartley, Gareth G. Roberts, Nicky White & Chris Richardson Sedimentary basins in the North Atlantic Ocean preserve a record of intermittent uplift during Cenozoic times. These variations in elevation are thought to result from temperature changes within the underlying Icelandic mantle plume. When parts of the European continental shelf were episodically lifted above sea level, new landscapes were carved by erosion, but these landscapes then subsided and were buried beneath marine sediments. Here, we use three-dimensional seismic data to reconstruct one of these ancient landscapes that formed off the northwest coast of Europe during the Palaeocene–Eocene Thermal Maximum. We identify a drainage network within the landscape and, by modelling the profiles of individual rivers within this network, we reconstruct the history of surface uplift. We show that the landscape was lifted above sea level in a series of three discrete steps of 200–400 m each. After about 1 million years of subaerial exposure, this landscape was reburied. We use the magnitude and duration of uplift to constrain the temperature and velocity of a mantle-plume anomaly that drove landscape formation. We conclude that pulses of hot, chemically depleted, mantle material spread out radially beneath the lithospheric plate at velocities of ∼35 cm yr−1.

Description: The Governor Lake area, Meguma terrane, Nova Scotia, is underlain mainly by ca. 373 Ma granitoid rocks of the Trafalgar plutonic suite that intruded metasedimentary rocks of the Goldenville and Halifax groups. Garnet is abundant in the Beaverbank Formation of the Goldenville Group and its enclaves in the granitoid rocks. Single crystals of garnet, locally up to 3 cm in diameter, are also present in the Twin Lakes granodiorite and Bog Island Lake tonalite. On the basis of petrographic examination and electron-microprobe data, we have identified four different types of garnet. Type-1 garnet, generally associated with coticule xenoliths, forms small spessartine-rich (Sps19-74) grains concentrated in irregular to planar aggregates. Crystals range from homogeneous (type 1A) to zoned toward a Mn-enriched rim (type 1B). Type-2 garnet is restricted to metasedimentary host rocks, where it forms small, spessartine-rich (Sps22-71) grains zoned from a Mn-rich core to a Mn-poor rim. Type-3 garnet contains abundant metamorphic inclusions (e.g., sillimanite) and commonly has an inclusion-rich core with an inclusion-poor rim. Type-3A crystals have a Mn-rich core (Sps21-52), whereas type-3B crystals have a Mn-rich rim (Sps15-21). Type-4 garnet forms large, subhedral to euhedral crystals with abundant inclusions (e.g., apatite, plagioclase) of probable igneous origin. Type-4A garnet is spessartine-poor (Sps4-11) and weakly zoned, whereas zoning in type-4B crystals suggests that a Mn-poor core (Sps8-16) was partially resorbed and overgrown by a Mn-rich rim (Sps11-26). Of the various types of garnet identified in the granitic samples, types 1A and 3B are interpreted as orthoxenocrysts, type 1B, as paraxenocrysts, type 3A, as having an orthoxenocrystic core overgrown by an orthomagmatic or paraxenocrystic rim, and types 4A and 4B, as orthomagmatic. The presence of Mn-rich xenocrystic garnet suggests that the Twin Lakes and Bog Island Lake plutons were contaminated by manganiferous rocks, probably derived from the Beaverbank Formation. Incorporation and assimilation of Mn-rich material may also have led to crystallization of orthomagmatic garnet in the granitic magmas.
