Theoretical Concerns In the Geometric Abstractions of Peter Halley
… aesthetic theory that forms the basis for Peter Halley's artistic program. While Halley has been the subject of numerous articles and interviews, there are no full length monographs on the artist that examine the progression of his work from its emergence in the early eighties to the mature work …

An improvement of back propagation algorithm using halley third order optimisation method for classification problems
… endeavours to propose a new computational Halley method which is third order optimisation in improving the learning efficiency of BP algorithm namely Halley with Broyden-Fletcher-Goldfarb�Shanno (H-BFGS) and Halley with Davidon-Fletcher-Powell (H-DFP). The efficiency of the proposed methods …

Sir Isaac's Duel (Original play)
The play Sir Isaac's Duel concentrates on Edmond Halley's discovery of the genius of Isaac Newton. Halley attempts to bring Newton's theories out to the public, Newton refuses, and the "duel" begins. Other characters in the play are as follows: Mary Halley, the wife of Edmond; Catherine Barton, …

Chemistry of the sea ice/ snowpack/ atmosphere system in coastal Antarctica
… made at the British Antarctic Survey station Halley, in coastal Antarctica, using a Chemical Ionisation Mass Spectrometer (CIMS). During specific periods in the spring the CIMS was configured to measure concentrations of BrO, Br2 and BrCl. In addition, concurrent measurements of surface ozone …

Familias paramétricas de procesos iterativos de alto orden de convergencia
… cubic convergence: Chebyshev's method, the Super-Halley method, the Halley method or the Euler method, as well as other families of iterations. We gradually relax the hypotheses of semilocal convergence that are usually used and obtain the domains where solutions are located and unique, together …

Aerosol chemistry and air-snow transfer in coastal Antarctica
… were made from British Antarctic Survey base, Halley. Aerosol and snow sea salt were found to have maximum concentrations during the austral winter and non sea salt sulphate and methane sulphonic acid concentrations peaked during the summer, confirming previous work by other authors.These …

The Investigation of the HLA System and Wheat Gluten in Determining Risk of Schizophrenia
Genome-wide association (GWA) studies confirmed that the HLA genes were<br/>strongly associated with schizophrenia but the HLA variants identified by GWA<br/>studies had a lower frequency in patients with schizophrenia than control subjects. The HLA molecules have function of presenting peptide …

Public health implications of hot summer days and vulnerability indexes in Massachusetts
Due to ever-increasing summer temperatures and a population with minimal technological adaptations to help them cope, extreme heat events will likely have a large impact on vulnerable populations in Massachusetts. As such, heat events are likely to impact the health of residents because they are …

Fracture path transitions in peels tests of medium carbon steel spot welds
Fracture path transition, from interfacial fracture to a pulled button, in peel tests of spot welds in SAE 1039 steel was evaluated to determine the controlling material properties. Welds were tested in the as welded condition and after tempering at various temperatures to develop a range of …

Evaluating abrasive wear resistance of extruder tooling materials using the dry sand rubber wheel abrasion test
A series of experiments was performed on groups of samples made from materials currently used to manufacture tooling for extruders to determine if the ASTM G65 dry sand rubber wheel abrasion test could be used as an accelerated test to evaluate candidate materials. Samples were tested in the heat …
