Description : Recent developments in the use of electrospun fibrous materials, for application as scaffolds for tissue engineering and in the application of carbon fibrous materials in fuel cells, has generated new interest in the dependence of the properties and structure of these materials on those of their constituent fibres. "Modelling Stochastic Fibrous Materials with Mathematica" provides an overview of the structure of stochastic fibrous materials, and the use of Mathematica to develop models describing their structure and performance. "Modelling Stochastic Fibrous Materials with Mathematica" provides an introduction to the techniques of statistical geometry and probabilistic modelling for non-mathematicians, and assumes no previous experience of Mathematica.Using accessible notation and by providing examples of Mathematica code, expressions are derived for the structural characteristics of stochastic fibrous materials providing insights into the ways these depend upon each other and the extent to which they can be modified in the laboratory or in a manufacturing environment. "Modelling Stochastic Fibrous Materials with Mathematica" is a valuable resource for researchers and engineers in industries concerned with electrospinning and the development of nonwoven fibrous architectures for use in composites, fuel cells and filtration applications.

Geometry Expressions is the first software package that allows you to interact with their numeric and symbolic. This interaction brings together geometry and algebra symbolic, for the first time in an interactive geometry. This interaction brings together geometry and algebra symbolic, for the first time in an interactive geometry.

The benefits of this type of system are:
* Many geometric configurations are much more easily with the constraints specified by construction. Many geometric configurations are much more easily with the constraints specified by construction.
* This is a much more convenient style for expressing real world problems. It is a style much more convenient to express real world problems.
* This is the approach used in modern Computer Aided Design (CAD). This is the approach used in modern Computer Aided Design (CAD).

LightWave® v9 is the perfect combination of power, speed and value. Long considered one of the easiest 3D animation systems to learn and use, LightWave 3D® is versatile enough for any application from award-winning visual effects to stunning hi-res print graphics, dynamic video games, powerful motion graphics and more. LightWave offers modeling, animation, dynamics, volumetric rendering, particle effects and a motion picture quality rendering engine with unlimited render nodes making LightWave the centerpiece of the most cost effective 3D production pipelines in the world.

LightWave 3D is a complete solution right out of the box that includes three different operating systems to meet your particular production requirements: Windows® 32-bit, Windows 64-bit and Macintosh®. LightWave for each operating system comes with unlimited render nodes. LightWave also supports the latest generation of dual-core and multi-core processor systems at no additional cost.

LightWave v9 introduces new interface paradigms, such as a Node Editor for materials and surfaces, volumetric lights, and displacements. Exciting new physically correct cameras have been added, allowing artists to recreate any real world camera lens, and have footage rendered in LightWave match real world photography (a must for compositing CGI and real footage together). These cameras can also be extended into the hyper-real, or even bizarre, as any mesh object can itself be made into a camera and record a scene. The possibilities are limitless.

New techniques for displacement mapping, and support for ZBrush® displacements have been added. New shading models, such as Blinn, Oren- Nayar, and Ambient Occlusion now allow for a tremendous versatility for artists no longer bound by the original shading model in previous versions of LightWave. Of particular note are the new shaders for sub-surface scattering, anisotropic specular and refl ection shaders (which allow for hromatic aberration), easy to use and offering a spectacular visual impact.
