Science Nation - Visualization Wall

submitted by: nsf
This 3-D experience even allows students to practice surgical techniques. When data becomes too complex to describe or even imagine, try bouncing it off a wall. But not just any wall. Measuring 14-by-8 feet, this giant behemoth is known as the VisWall (a product of Visbox, Inc.) and it can help researchers visualize some of the most complicated scientific concepts.

Design Principles for Visual Communication

submitted by: wilmotli
Visual communication via diagrams, sketches, charts, photographs, video, and animation is fundamental to the process of exploring concepts and disseminating information. The most-effective visualizations capitalize on the human facility for processing visual information, thereby improving comprehension, memory, and inference. Skilled designers create such visualizations by applying cognitive design principles that define how visual techniques can be used to emphasize important information...

CPU vs GPU: AMBER Code Simulation

submitted by: btolo

The terminal view on the left shows a 'tail' of the AMBER code output for a simulation of Myoglobin, a protein found in muscle fibers. In this video, the output is being run on a single Intel E5462 2.80 GHz CPU. The terminal view on the right shows the same AMBER code output, but run on a single NVIDIA C1060 GPU. The GPU run is about 40 times faster than the CPU run.

Modeling Early Galaxies Using Radiation Hydrodynamics

submitted by: btolo
This simulation uses a flux-limited diffusion solver to explore the radiation hydrodynamics of early galaxies, in particular, the ionizing radiation created by Population III stars. At the time of this rendering, the simulation has evolved to a redshift of 3.5. The simulation volume is 11.2 comoving megaparsecs, and has a uniform grid of 1024^3 cells, with over 1 billion dark matter and star particles. The simulation was computed on resources of the National Institute for Computational...

High resolution tomographic imaging of the alveolar region of the mammalian lung

submitted by: habi

The video is an overview of my work in the last 3.75 years at the Institute of Anatomy. It was the talk I gave as my PhD-Defense. My main work was the radiation-optimized increase in the field of view of tomographic imaging stations, thus most of the time of my talk was spent on this.
