Acoustic surface wave delay device

Creator:: Bhaskar, Eldurkar Vamanrao
Abstract:: This thesis is an experimental study of an acoustic surface wave delay line using a Lithium Niobate crystal. A brief theory of operation of the interdigital transducer with its advantages over the other methods of exciting and detecting acoustic surface waves is discussed. The experimental procedure used for evaluation of...

The role of acoustical signals in the communicative behavior of the water scavenger beetles, Tropisternus (Coleoptera:hydrophilidae)

Creator:: Ryker, Lee Chester
Abstract:: The communicative behavior of five species and subspecies of Tropisternus Solier (Coleoptera: Hydrophilidae) was studied. These aquatic beetles have stress and calling chirps (both sexes), a second male calling signal (one species), a single male courtship sound (usually), a male copulatory sound, and a female aggressive rejection buzz (three species)....

On the diffraction of a cylindrical pulse by a half plane

Creator:: Barr, George Earl
Abstract:: The effect of a pulse produced by an acoustic or electromagnetic line source oriented parallel to the edge of a perfectly conducting half plane is considered. The Green's functions for the modified Helmholtz equation are found by solving for the Green's functions for a cylinder of sectorial cross-section, then allowing...

A device for investigating wave phonomena by means of sound

Creator:: Jenne, Everett Knowlton
Abstract:: Sound waves are very convenient for the investigation of all wave phenomena with the exception of polarization. They are particularly useful in connection with microwaves because the latter's wave length can be easily duplicated with sound waves, making it possible to obtain the same diffraction pattern for both when confronted...

Sound production in three sympatric Ips (Coleoptera:Scolytidae) species co-inhabiting Sitka spruce (Picea sitchensis)

Creator:: Oester, Paul T.
Abstract:: Three sympatric species of Ips, colonizing Sitka spruce, were investigated with regard to their infestation habits, stridulating apparatus and acoustic signals. The above phenomena are evaluated qualitatively and/or quantitatively and the acoustic signal differences are proposed as a possible factor for maintaining species isolation, although function is not shown. Field...

The effects of sewage on the distribution and abundance of benthic animals in a Puget Sound bay

Creator:: Shapeero, William L.
Abstract:: The effects of discharged sewage on physico-chemical conditions and the distribution and abundance of marine benthic animals were studied in Shilshole Bay, a part of Puget Sound, off Seattle, Washington. For over 50 years prior to 1965, when this study was initiated, 87,300 pounds (32,400 pounds BOD) per day of...

Breeding habitat of harlequin ducks in Prince William Sound, Alaska

Creator:: Crowley, David W.
Abstract:: Breeding habitat of Harlequin ducks (Histrionicus histrionicus) was studied in eastern Prince William Sound, Alaska, during 1991 - 1993. Streams in Prince William Sound were surveyed for Harlequin ducks and monitored with mist nets. Physical characteristics of 24 Harlequin breeding streams were compared to those of 24 streams not used...
