TL;DR: The effect of neutron irradiation on the tensile properties of TZM and tungsten has been experimentally determined in this paper, and the results of these tests were correlated with a rate-temperature parameter (T ln A ϵ ) to provide a concise description of material behavior over the range of deformation conditions.

TL;DR: In this article, the fracture toughness of epoxy and polyethersulfone was measured using three point bend tests (ASTM: E-399-81), and the influence of the morphology of the epoxy/polyether sulfone blend on its fracture toughness and toughening mechanism has been studied.
Abstract: Compatibility or miscibility of a polyethersulfone (ICI: Victrex 100P) and a tetrafunctional epoxy (Ciba-Geigy: MY-720), cured with an aromatic anhydride, has been studied using scanning electron microscopy, x-ray microanalysis, and dynamic mechanical spectroscopy. Fracture toughness of epoxy and a blend of epoxy and polyethersulfone has been measured using three point bend tests (ASTM: E-399-81). Fracture surfaces were examined by x-ray microanalysis for detecting concentration of sulfur, present in polyethersulfone, in the matrix and precipitated phase. The influence of the morphology of the epoxy/polyethersulfone blend on its fracture toughness and toughening mechanism has been studied. Fracture toughness values of unmodified and modified cured epoxy resin were evaluated as a function of test temperature.

TL;DR: In this paper, a new hypothesis is considered which explains this variation of mobility in terms of changes in the concentration of vacancies at the grain boundaries, which does not seem to be due to impurities.

16 Sep 1991TL;DR: In this article, a series impedance compensation system for a set of transmission lines which are used for electrical power transmission, with these parallel lines being protected from the transient faults and dynamic subsynchronous oscillation problems, is presented.
Abstract: A series impedance compensation system for a set of transmission lines which are used for electrical power transmission, with these parallel lines being protected from the transient faults and dynamic subsynchronous oscillation problems. These problems can become aggravated by the introduction of capacitor banks which thus serve as only a partial solution to the disturbances of transient faults during conventional recovery modes of operation. The impedance compensation system is coupled in series to each transmission line to dynamically balance the inductor impedance on the transmission line, responsive to demand, by injecting a voltage component determined to be optimized substantially at quadrature leading or lagging phase angles (±90°) with respect to the transmission line voltage and current components. The impedance compensation system includes a circuit based solid-state switching power converter with self-commutating thyristor or GTO semiconductor switches connected in a parallel shunting arrangement with reverse poled or freewheeling diodes. This is done in order to provide either an absorptive component or a generated component of output pole voltage carrying a 90° segment of the output current in each cycle, as this provides dynamic stability without fostering subsynchronous resonance.

31 Jan 1975TL;DR: In this article, a distribution network power line communication system which is divided into addressable communication zones defined by repeaters located at the distribution transformers of the distribution network is described, where each repeater, when uniquely addressed by an interrogation signal from an interrogating source, strips its address from the interrogation signal and sends the resulting modified interrogation signal to its associated remote communication terminals, bypassing the associated distribution transformer.
Abstract: A distribution network power line communication system which is divided into addressable communication zones defined by repeaters located at the distribution transformers of the distribution network. Each repeater, when uniquely addressed by an interrogation signal from an interrogating source, strips its address from the interrogation signal and sends the resulting modified interrogation signal to its associated remote communication terminals, by-passing the associated distribution transformer. A timely, error-free response signal from a remote communication terminal is modified by a repeater to include the repeater address, and the modified response signal is sent back to the interrogating source. The binary base band interrogation and response signal information is preferably pulse width modulated to provide a self clocking format, and this self clocking signal is passed through two stages of frequency modulation to provide a signal which makes the receivers thereof substantially immune from drift.
