The Casper Company Building
No full textThe Casper Company was located at 1045 Liberty Street in Winston-Salem. This image captures three unidentified people standing outside the building with an unidentified woman in the carriage being drawn by a horse. The signage on the building reads, "THE CASPER COMPANY, INC. / DISTILLERS RECTIFIERS & BOTTLERS / AGENTS FOR PABST BLUE RIBBON BEER." The sign on the side of the building reads, "CASPER'S / SWEET MASH / CORN / WHISKEY.
Extending CasPer: A Regression Survey
No full textThe CasPer algorithm is a constructive neural network algorithm. CasPer creates cascade network architectures in a similar manner to Cascade Correlation. CasPer, however, uses a modified form of the RPROP algorithm, termed Progressive RPROP, to train the whole network after the addition of each new hidden neuron. Previous work with CasPer has shown that it builds networks which generalise better than CasCor, often using less hidden neurons. This work adds two extensions to CasPer. First, an enhancement to the RPROP algorithm, SARPROP, is used to train newly installed hidden neurons. The second extension involves the use of a pool of hidden neurons, each trained using SARPROP, with the best performing neuron selected for insertion into the network. These extensions are benchmarked on a number of regression problems and are shown to result in CasPer producing networks which generalise better than those produced by the original CasPer algorithm. 1 Introduction The CasPer algorithm has b..

CASPER: Concordia atmospheric spectroscopy of emitted radiation
No full textCASPER (Concordia Atmospheric Spectroscopy of Emitted Radiation) is a spectrometer proposed for installation at Dome C, devoted to measurements of atmospheric emission in the spectral region between 180 μm and 3 mm (3-55 cm-1). This instrument will be able to perform continuous spectral sampling at different altitudes at angular scales of ∼1°. From the recorded data it is possible to extract atmospheric transmittance within 1% in the whole wide operating band, together with water vapour content and O 2 and O3 concentrations. CASPER will allow us to characterize the site for future FIR/mm telescopes. Atmospheric data recorded by CASPER will allow for correction of astrophysical and cosmological observations without the need for telescope-specific procedures and further loss of observation time with more precision in the observations themselves. Calibration of ground-based telescopes on known sky sources is strongly affected by atmospheric absorption. CASPER has this as its primary goal. The spectrometer is based on a Martin-Puplett interferometer. Two data sampling solutions will be performed: phase modulation & fast scan strategy. Sky radiation is collected towards the interferometer by an optical setup that allows the field of view, to explore the full 0 ÷ 90° range of elevation angles. With a low spurious polarization instrument, monitoring of polarized atmospheric contribution will be possible. © EAS, EDP Sciences 2005

CASPER coupled air-sea processes and electromagnetic ducting research
No full textThe Coupled Air–Sea Processes and Electromagnetic Ducting Research (CASPER) project aims to better quantify atmospheric effects on the propagation of radar and communication signals in the marine environment. Such effects are associated with vertical gradients of temperature and water vapor in the marine atmospheric surface layer (MASL) and in the capping inversion of the marine atmospheric boundary layer (MABL), as well as the horizontal variations of these vertical gradients. CASPER field measurements emphasized simultaneous characterization of electromagnetic (EM) wave propagation, the propagation environment, and the physical processes that gave rise to the measured refractivity conditions. CASPER modeling efforts utilized state-of-the-art large-eddy simulations (LESs) with a dynamically coupled MASL and phase-resolved ocean surface waves. CASPER-East was the first of two planned field campaigns, conducted in October and November 2015 offshore of Duck, North Carolina. This article highlights the scientific motivations and objectives of CASPER and provides an overview of the CASPER-East field campaign. The CASPER-East sampling strategy enabled us to obtain EM wave propagation loss as well as concurrent environmental refractive conditions along the propagation path. This article highlights the initial results from this sampling strategy showing the range-dependent propagation loss, the atmospheric and upper-oceanic variability along the propagation range, and the MASL thermodynamic profiles measured during CASPER-East
