Uncertainty arises in all stages of the visualization pipeline. However, the majority of flow visualization applications convey no uncertainty information to the user. In tools where uncertainty is conveyed, the focus is generally on data, such as error that stems from numerical methods used to generate a simulation or on uncertainty associated with mapping visualization primitives to data. Our...

Seeding effects on the microstructure and mechanical properties of single-phase Ca-α-SiAlON ceramics have been investigated. Whereas a small amount of seeds can transform the microstructure from one of fine equiaxed grains to one consisting of many needle-like grains, the highest fracture toughness of 8 MPa . m1/2 is not reached until 8% seeding. This contrasts with the much higher seed efficie...

A study of rainfall stimulation was made with the aim of assessing its economic potential for the Natal cane belt. High variability of precipitation in both space and time makes the determination of requirements and effects of large scale seeding programmes very difficult. Evaluation of field and laboratory tests have, however, identified two conditions under which seeding could increase precip...

Surface acoustic waves (SAW) have been employed to drive a particle suspension into a porous scaffold as a means for cell seeding. Straight, simple interdigital electrode structures were fabricated on lithium niobate to permit the generation of Rayleigh SAW radiation. Fluorescent microscopy was used to investigate the seeding process; the SAW-driven seeding process occurred in approximately 10s...

The use of glyphosate resistant soybean (GRS) cultivars has increased rapidly from their introduction in 1996 to over 50% of Wisconsin soybean acres in 1999. While much research has been conducted using conventional cultivars to measure the influence of row spacing and seeding rates on soybean growth and yield, little has been done with new GRS cultivars. It may be necessary and/or more profita...

Selective intra-arterial chemotherapy (IAC) has been adopted by many ocular oncology centers to treat advanced intraocular retinoblastoma. In this report, we describe two patients with unilateral intraocular retinoblastoma and persistent vitreous seeding, who were treated with IAC after failed systemic chemotherapy. Despite multiple sessions and increasing dosage of drug delivery, vitreous seed...

The spread of neurofibrillary tangle (NFT) pathology through the human brain is a hallmark of Alzheimer's disease (AD), which is thought to be caused by the propagation of "seeding" competent soluble misfolded tau. "TauC3", a C-terminally truncated form of tau that is generated by caspase-3 cleavage at D421, has previously been observed in NFTs and has been implicated in tau toxicity. Here we s...

The visualisation of 3D flow poses many challenges. Difficulties can stem from attempting to capture all flow features, the speed of computation, and spatial perception. Streamlines and stream surfaces are standard tools for visualising 3D flow. Although a variety of automatic seeding approaches have been proposed for streamlines, little work has been presented for stream surfaces. We present a...

22-151 ABSTRACT The main objective of this study was to evaluate the effectiveness and improved productivity of reduced tillage pasture renovation methods in the establishment of triple species pasture mixtures into an existing naturalized stand. Experimental treatments, 2 (low and high stocking rates) by 2 (frostand sod-seeding methods) factorial with an additional non-renovated pasture contro...

We study the power of a tournament organizer in manipulating the outcome of a balanced single-elimination tournament by fixing the initial seeding. This problem is known as agenda control for balanced voting trees. It is not known whether there is a polynomial time algorithm that computes a seeding for which a given player can win the tournament, even if the match outcomes for all pairwise play...
