Direct volume rendering (DVR) is a very useful visualisation technique. However, the difficulty in specifying a suitable transfer function often discourages its application to visualisation problems. This work presents a technique for providing meaningful and fast visual feedback that greatly facilitates the transfer function specification process. The feedback is based on a slice-based preview...

We report preliminary results of lattice super-Yang-Mills computations using domain wall fermions, performed at an actual rate of 1000 Gflop/s, over the course of six months, using two BlueGene/L racks at Rensselaer’s CCNI supercomputing center. This has allowed us to compute the gluino condensate and string tension over a wide range of lattice parameters, setting the stage for continuum, chira...

The structure of β-Mn crystallizes in space group P4132. The pseudo 8-fold nature of the 41 axes makes it constitute an approximant to the octagonal quasicrystals. In this paper we analyze why a five-dimensional super space group containing mutually perpendicular 8-fold axes cannot generate P4132 on projection to 3-d space and how this may instead be accomplished from a six-dimensional model. A...

We describe geometrical algorithms for interface reconstructions for 3D generalized polyhedral meshes. Three representative piece-wise linear interface calculation methods are considered, namely gradient based method, least squares volume-of-fluid interface reconstruction algorithm, and moment-of-fluid method. Geometric algorithms for the 3D interface reconstructions are described. Algorithm fo...

to investigate the effects of drought stress and different combinations of animal manure with super absorbent polymer on yield and yield components of corn, a split plots design was conducted based on a randomized complete block design with 3 replications in fars agricultural research center in 2007. irrigation treatments were assigned as the main factor in three levels: 70, 105 and 140 mm evap...

Manufacturing performances tend to produce defects due to various reasons which can be improved by identifying and eliminating them using six sigma. In the present work, DMAIC (Define, Measure, Analyze, Improve and Control) has been used to reduce the number of vehicle engine rejection. In define phase problem was defined by selecting the core issues concerned. In the measure phase data was col...

A number of recent advances in our understanding of scattering amplitudes have been inspired by ideas from twistor theory. While there has been much work studying the twistor space support of scattering amplitudes, this has largely been done by examining the amplitudes in momentum space. In this paper, we construct the actual twistor scattering amplitudes themselves. This gives a formulation of...

Constructed wetlands are gaining increased attention for treatment of nonpoint sources of water pollution. Although constructed wetlands have been utilized for wastewater treatment in warm climates, their performance in cold climates has been questioned. A surface-flow wetland, designed to treat 2.65 m super(3) d super(-1) of milkhouse wastewater, was constructed on the University of Connecticu...

Several of the inconsistencies plaguing the field of novae are resolved once we consider novae to be steady state super-Eddington objects. In particular, we show that the super-Eddington shell burning state is a natural consequence of the equations of stellar structure, and that the predicted mass loss in the super-Eddington state agrees with nova observations. We also find that the transition ...
