A method for the calculation of spectral line broadening in plasma has been developed and implemented. The method is based on a numerical simulation of the motion of the interacting plasma particles (both ions and electrons) and the use of the resulting time-dependent field to obtain the evolution of the radiator system. The Fourier transform of the resulting radiator time-dependent dipole func...

A preventable subgroup of motor vehicle injuries is burns from motor-vehicle radiators. Such burns can have a significant impact on return to work and patient psychological wellbeing.1 These injuries are commonly scald burns, often occurring following attempts to remove the lid of a hot radiator with high pressure or explosion of the radiator. This results in a spray of superheated fluid and st...

Bistability is common in nonlinear dynamical systems, but there have been no reports of intrinsic instabilities in black-body emission of optically excited media. Intrinsically bistable photo-luminescence has been reported however in Yb-doped heavy metal halide crystals at cryogenic temperatures and also in room temperature experiments in rare-earth-doped laser glass and transition metal laser ...

A very thin, solid radiator, totally internally reflecting, imaging Cherenkov counter (DIRC) is described. This device is well matched to the hadronic charged particle identification requirements at an asymmetric e+eB Factory.

In this paper, a novel design of a compact planar ultra wide band (UWB) monopole antenna with triple band notched characteristics has been presented. The antenna has a unique shape and has been fed through a 50 Ω microstrip feedline. The strength of the antenna lies in three band notched properties for WiMax system at 3.3 3.7 GHz, WLAN IEEE 802.11a at 5.15 5.85 GHz and X band satellite communic...

We discuss the development of a simplified model for the jet noise source that can be used in practical predictions of installed noise. In the proposed scheme, the source is prescribed on a radiator surface defining the boundary between the inner rotational jet flow and the outer linear pressure field. The source consists of wavepacket-type partial fields whose noise propagation can be computed...

This paper presents an analysis of solar-heat driven Brayton, Rankine and Stirling cycles operating in space with different working fluids. Generation of power in space for terrestrial use can represent a great future opportunity: the low-temperature of space (~3 K), allows the attainment of very high efficiency even with low-temperature heat inputs, and the solar energy input is higher in spac...

Direct-radiator loudspeakers typically have a very low efficiency since the acoustic load on the diaphragm or cone is relatively low compared to the mechanical load, and in addition the driving mechanism of a voice coil is quite inefficient in converting electric energy into mechanical motion. The drivers have a magnetic structure that is deliberately kept mediocre so that the typical response ...
