Stereoscopic sequence compression typically involves the exploitation of the spatial redundancy between the left and right streams to achieve higher compressions than are possible with the independent compression of the two streams. In this paper the psychophysical property of the human visual system, that only one high resolution image in a stereo image pair is sufficient for satisfactory dept...

Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic selection methods were proposed. Local methods support the selection of a set of stream surfaces, but, contrary to global selection methods, they evaluate only the quality of...

The Magnetic Cataclysmic Variables (MCVs) are close interacting binaries where mass is transferred from a late type secondary star to a magnetic white dwarf. Two modes of accretion can be identified depending on the strength of the magnetic field, the mass transfer rate and orbital parameters. (a) Disced Accretion: In the Intermediate polars (IPs), the mass transfer stream circularises and form...

Aims. Emission lines in polars show complex profiles with multiple components that are typically ascribed to the accretion stream, threading region, accretion spot, and the irradiated secondary-star. In low-state polars the fractional contribution by the accretion stream, and the accretion spot is greatly reduced offering an opportunity to study the effect of the secondary-star irradiation or s...

1. Mice with relatively great inherent resistance to certain bacterial infections were heavier but not more fertile than mice with relatively little inherent resistance. Mice with relatively little inherent resistance were with one exception not abnormally low in weight. 2. B. enteritidis given intrastomachally to susceptibles appeared in the blood stream more promptly, in larger numbers, and i...

Dashed lines are a common, and semantically important, element in line drawings. This paper deals with the inference of a dashed lines’ grammar, given a stream of graphical symbols. A method is presented, based on syntactical pattern recognition, capable of inferring arbitrary grammars without a priori knowledge. A detailed complexity-analysis of the developed algorithms is presented, as well a...

Since the lung cancer cell (LCC) has direct access to the pulmonary vein, left heart and aorta, it has an optimum opportunity for distant dispersal. However, at necropsy, there are as many as ten dispersal patterns which are anomalous in terms of the hematogenous theory of metastasis. As such anomalies may imply imperfections in current concepts, the hematogenous route deserves comparison with ...

A method of using a dynamic texture map on 3D polylines to represent field streamlines is described, for the purpose of visualizing continuous fluid dynamics fields. The method combines stream lines and particle animation into one hybrid technique, and employs texture display on lines to represent full 3D lighting, motion and 3D flow structure in one view. The technique exploits texture graphic...

Time-resolved spectroscopy of the novalike variable UU Aquarii is analyzed with eclipse mapping techniques to produce spatially resolved spectra of its accretion disc and gas stream as a function of distance from disc centre in the range 3600-7000Å. The spectrum of inner disc shows a blue continuum filled with deep, narrow absorption lines which transition to emission with clear P Cygni profile...

We measured larval growth rates of 2 dominant stream detritivore groups to assess the mechanism underlying declines in invertebrate production following exclusion of terrestrial litter inputs to a forested headwater stream. Larval Tallaperla spp. (Plecoptera:Peltoperlidae) were chosen as representative shredders and non-Tanypodinae Chironomidae (Diptera) were selected as representative collecto...
