Abstract: Methods of controlling the durability of and/or the amount of air in concrete formulations that include combining cement, water, and optionally aggregates, admixtures and/or additives to form a cement mixture; and adding prepuff particles to the cement mixture to form a concrete formulation. The prepuff particles have an average particle diameter of from 0.2 mm to 3 mm, a bulk density of from 0.015 g/cc to 0.35 g/cc, an aspect ratio of from 1 to 3, and a smooth continuous outer surface. The cured and hardened concrete formulation typically has a relative dynamic modulus of at least 70% determined according to Procedure A of ASTM C666 (2003). The amount of air in the concrete typically increases over the amount of air in similar formulations not containing prepuff particles, as determined according to ASTM C231, based on the volume percent of prepuff. The concrete formulations can be used to make articles.

Abstract: The PENT value for a resin may be estimated within ±10% by determining the % of heat flow to melt a fraction of a polymer above or below a set point and comparing it to a graph or algorithm of PENT values related to the % of heat flow to melt entire sample for a number of resins made using the same catalyst system. In a similar manner one may estimate the process conditions to prepare a polymer having a target PENT value based on the conditions used to prepare the samples for the graph or algorithms. The invention provides a simple procedure that may be used at a manufacturing site to estimate PENT values.

Abstract: A readout electronics scheme is under development for high resolution, compact PET (positron emission tomography) imagers based on LSO (lutetium ortho-oxysilicate, Lu2SiO5) scintillator and avalanche photodiode (APD) arrays. The key is to obtain sufficient timing and energy resolution at a low power level, less than about 30 mW per channel, including all required functions. To this end, a simple leading edge level crossing discriminator is used, in combination with a transimpedance preamplifier. The APD used has a gain of order 1,000, and an output noise current of several pA/?Hz, allowing bipolar technology to be used instead of CMOS, for increased speed and power efficiency. A prototype of the preamplifier and discriminator has been constructed, achieving timing resolution of 1.5 ns FWHM, 2.7 ns full width at one tenth maximum, relative to an LSO/PMT detector, and an energy resolution of 13.6% FWHM at 511 keV, while operating at a power level of 22 mW per channel.

Abstract: A variable acuity imager incorporates an array of detection elements for light energy, in the visible, infrared, ultraviolet, or light energy in another region of the electromagnetic spectrum with a means to change the spatial configuration of the array to include “superpixels” by combining energy detected by adjacent elements, thus permitting any number of high-resolution “foveal” regions to be placed within the confines of the focal plane array and moved around at the frame rate of the imaging device. Detectors to measure the pitch, yaw and roll angle rates of background imagery using velocity-sensing circuitry are employed for variation of the foveal regions to accommodate motion of the array.

The method can include formulating a finite element model of the behavior of a coupled solid-fluid formation, having complex geometry and behavior, and applying the model to derive the response of the formation in the form of one or more displacement fields for the solid phases and one or more pressure fields for the fluid phases in a zone of interest in a formation. In an exemplary embodiment, a system is disclosed for estimating the uncertainties in the derived displacement and pressure field solutions for the response of the fully coupled solid-fluid phases.
