A multiwavelength study of a double impulsive flare
Solar Physics, 1984Extensive data from the Solar Maximum Mission (SMM) and ground-based observatories are presented for two flares; the first occurred at 12:48 UT on 31 August, 1980 and the second just 3 min later. They were both compact events located in the same part of the active region.

A Double-wall Noise Control Enclosure for an Impulsive Sound Source
American Industrial Hygiene Association Journal, 1961Abstract The design of a group of double-wall noise control enclosures on the upper floor of an existing building is described and some noise reduction measurements are reported. A design objective for these enclosures was to achieve more effective noise reduction than that provided by existing heavy, on-grade, double-wall, reverberant enclosures, but ...

FINITE IMPULSE RESPONSE DOUBLE DENSITY FILTER BANKS AND FRAMELETS
International Journal of Wavelets, Multiresolution and Information Processing, 2013In this paper, we focus on the design of oversampled filter banks and the resulting framelets. The framelets obtained exhibit improved shift invariant properties over decimated wavelet transform. Shift invariance has applications in many areas, particularly denoising, coding and compression. Our contribution here is on filter bank completion.

Impulse studies of double diffraction: A discrete Huygens interpretation
The Journal of the Acoustical Society of America, 1982A closed-form analytical impulse solution of diffraction by a rigid wedge is interpreted from the point of view of discrete Huygens wavelets emanating from the crest of the wedge. The strengths of these secondary sources and the impulse field diffracted over a second wedge are calculated.

Characteristics of a two-phase double-superimposed auxiliary impulse commutated chopper
1978 IEEE Power Electronics Specialists Conference, 1978This paper deals with circuit configurations, operations, characteristics and evaluations of a two-phase auxiliary impulse commutated chopper derived from the McMurray inverter. The auxiliary impulse commutated chopper is composed of at least two main thyristors which alternately repeat turn-on and turn-off during each cycle operation.

A rotating spark gap for double impulse experiments
IEE Colloquium on Pulsed Power '96, 1996The switching gap is the most important circuit component in a high-voltage high-current generator. Usually these switching devices are in the form of triggered spark gaps. It is well known, that following high current sparking, the gap between the electrodes stays "hot" for some time, which affects the recovery time of the spark gap.

Impulse magnetic-field therapy for insomnia: A double-blind, placebo-controlled study
Advances in Therapy, 2001This 4-week double-blind, placebo-controlled study assessed the efficacy of impulse magnetic-field therapy for insomnia. One hundred one patients were randomly assigned to either active treatment (n = 50) or placebo (n = 51) and allocated to one of three diagnostic groups: (1) sleep latency; (2) interrupted sleep; or (3) nightmares.

Double Atrial Responses to a Single Ventricular Impulse in Long RP′ Tachycardia
Pacing and Clinical Electrophysiology, 1996Double atrial responses (DARs) to a single ventricular impulse have been described in patients with long RP' tachycardia. To define the determinants for the occurrence of DARs. 8 cases with long RP' tachycardia were examined. The mechanism of long RP' tachycardia was the orthodromic atrioventricular reciprocating tachycardia (AVRT) involving a slow ...
