Visual acuity is d&ned as the reciprocal of the visual angle, in minutes. subtended by a just resolvable stimulus. This critical dimension can be the gap in a Landolt C, the spatiat period of a grating or the offset of a vernier. etc. Acuity declines progressively from the fovea out to the periphery of the retina. It is down to half its maximum value at an eccentricity of only 30 min according ...

The influence of epidemics of infectious disease on the history of civilization is one of recurring interest, and one which has yet to be comprehensively studied; indeed until our knowledge of the extent and severity of the individual epidemics has been plotted no true measure of their effects can be made. Professor Shrewsbury in this work has attempted to do just this for bubonic plague. All f...

THE Black Death was part ofthe second pandemic ofplague which wrought inconceivable devastation throughout Europe during the Middle Ages. It invaded Europe from the East in the autumn of I347, and entered England through Weymouth early in August I348. By the end of 1349 it had spread all over the country and it remained until i666. During this time when the plague was domesticated there were fo...

Paris (PArallel, Robust, Interface Simulator) is a finite volume code for simulations of immiscible multifluid or multiphase flows. It based on the “one-fluid” formulation Navier–Stokes equations where different fluids are treated as one material with variable properties, and surface tension added singular interface force. The fluid solved regular structured staggered grid using an explicit pro...

--Key assumptions and components of biophysical models of hummingbird licking that are central to current interpretations of plant-pollinator coevolution have not previously been verified. To test the realism of the models, I measured fine-scale parameters of a Rufous Hummingbird's (Selasphorus rufus) licking, including licking frequency and volume extracted per lick, with a photodetector array...

Over the last two decades, there have been many high profile success stories where cutting edge computer graphics (CG) technology was used in collaboration with cultural heritage (CH) professionals to unlock the secrets of humanity’s legacy. Well known examples include the empirical 3D acquisition of Michelangelo’s David, the laser scan-based 3D mapping of the tombs found in the Valley of the K...

CIRCA: THE COOPERATIVE INTELLIGENT REAL-TIME CONTROL ARCHITECTURE by David John Musliner Co-Chairs: Kang G. Shin and Edmund H. Durfee The Cooperative Intelligent Real-time Control Architecture (CIRCA) is a novel architecture for intelligent real-time control that can guarantee to meet hard deadlines while still using unpredictable, unrestricted AI methods. CIRCA includes a real-time subsystem u...

The crustal history of volcanic rocks can be inferred from the mineralogy and compositions of their phenocrysts which record episodes of magma mixing as well as the pressures and temperatures when magmas cooled. Submarine lavas erupted on the Hilo Ridge, a rift zone directly east of Mauna Kea volcano, contain olivine, plagioclase, augite ‹orthopyroxene phenocrysts. The compositions of these phe...

Although Owatonna, Minnesota, enjoyed a limited amount of social library provision from the mid-nineteenth century onward, it was not until the 1890s that pressure mounted for a public library to be established under the terms of the State Library Act of 1879. The opportunity to provide a public library arose with a bequest from Mr. and Mrs. Elisha Hunewill, who had run a hardware business in t...

During February 2000, two trout farms, situated in NW Greece, reported unusually high losses of hatchery reared rainbow trout fry and fingerlings. Live fish and chilled samples of diseased whole fish were delivered to a veterinary laboratory in Athens for diagnostic investigation. Infections with the fungus Ichthyophonus hoferi as well as the Gram negative bacterium Aeromonas hydrophila were di...
