Magnetometer data, acquired on spacecraft and simultaneously at high and low latitudes on the ground, are compared in order to study the propagation characteristics of hydromagnetic energy deep in
The use of portable and hand-held terminals in 850-MHz cellular radio systems involves a radio field environment inside buildings that differs from the more familiar highway and street propagation
Photovoltaic diodes based on iodine- and bromine-doped pentacene single crystals as well as thin films (TFs) have been prepared.
At moderate temperatures in flowing gas, pentacene undergoes a disproportionation reaction to produce 6,13-dihydropentacene (DHP) and a series of polycondensed aromatic hydrocarbons, including the
It is difficult to deposit a very thin polymer layer onto a fiber-shaped substrate from solution because the high interfacial energy can lead to dewetting.
High K titanium oxide-polystyrene nanocomposite (TiO2-PS) has been blended with polystyrene (PS) to generate gate dielectric films with permittivities ranging from 2.5 to 8 in order to investigate
A detailed description of a current rural crossbar system.
Making effective use of the well-established Pentaconta switching equipment and techniques, the A1 system has been developed to fit in the public telephone network of North America.
The system uses cross-bar type multiswitches as selectors and special electromagnetic relays of high contact capacity for building up the associated units; markers, receivers, translators and so on
Describes the functioning and application of line concentrators which use the Pentaconta crossbar switch, a 14 detection bar multi-selector serving 52 outlets.
