High-sensitivity receiver systems with near-ideal polarization sensitivity are highly desirable for development of millimeter and submillimeter radio astronomy. Multimoded bolometers provide a unique solution to achieve such sensitivity, for which hundreds of single-mode sensors would otherwise be required. The primary concern in employing such multimoded sensors for polarimetery is the control...

A model is investigated describing the resistive dissipation of a finite, two-dimensional current sheet subject to suddenly enhanced resistivity. The resistivity rapidly diffuses the current to a distance where it couples to fast magnetosonic modes. The current then propagates away as a sheath moving at the local Alfvén speed. A current density peak remains at the X-point producing a steady ele...

Combined resistivity and IP investigation is a powerful tool for mapping contaminant leakage as well as delineating the extent of contaminated ground and buried waste. Resistivity investigation is well established for detection and mapping of contaminated ground and groundwater. Low resistive zones around contaminated industrial sites and landfills correlate with high ion contents in groundwate...

two dimensional single frequency scalar vlf data modeling has been studied in this research. vlf method is one of the electromagnetic investigation methods. radio frequency waves are used for investigation of conductive deposits (paal, 1968). synthetic modeling and inversion of single frequency and multiple frequencies of vlf signals was done by oskooi (2004) for two dimensional simple structur...

The paper demonstrates the preliminary research carried out on fibre meshed transducers for wearable computing applications, their constructions using electroconductive fibres via the route of modern electronic flatbed knitting technology. The paper reports the construction of resistive strain and displacement transducers using electroconductive polymeric fibres (resistivity of 10 cm) and metal...

In the resistive phase transition in VO2, temperature excursions taken from points on the major hysteresis loop produce minor loops. For sufficiently small excursions these minor loops degenerate into single-valued, nonhysteretic branches NHBs linear in log versus T and having essentially the same or even higher temperature coefficient of resistance TCR as the semiconducting phase at room tempe...
