Abstract: A technique for position based dynamics constrains deformation of triangles within a simulation mesh configured to model a cloth object. The constraints comprise at least a weft, warp, and shear constraint per triangle within the simulation mesh. A non-rigid shear constraint yields realistic cloth dynamics while avoiding locking within the simulation mesh. The technique may be implemented in real-time or batch simulation environments.

Abstract: A technique for physically-based cloth simulation uses linear upsampling operators. The upsampling operators enrich the appearance of a coarse mesh physical cloth simulation. The technique starts by pre-computing the upsampling operators using a pair of coarse and fine training simulations aligned with tracking constraints using harmonic test functions. Then the upsampling operators are trained using a novel regularization technique that enables mid-scale detail learning without over-fitting. Oscillatory modes may be introduced to add dynamic details not captured by the coarse mesh simulation alone. Trained upsampling operators can then be advantageously applied to coarse mesh simulations of cloth to add realistic detail to the cloth in real-time three-dimensional applications.

Abstract: The present invention concerns a carbon coated lithium metal phosphate material containing a manganese oxide layer between the LiMnPO4 material or the C/LiMn1-x ZxPO4 material, where Z=Fe, Co, Ni, Mg, Ca, Al, Zr, V, Ti and x=0.01-0.3, and the carbon layer.

Abstract: This invention concerns a novel method for surface derivatization of electrode materials for Li-ion batteries. The derivatization is based on adsorption of a composite assembly consisting of amphiphilic redox active molecule attached to single walled carbon nanotube (SWCNT). Its role consists in the enhancement of electronic conductivity of electrode materials, such as phosphate olivines, without requesting any significant increase of the electrode volume and mass. The SWCNT is linked to the redox molecule via non-covalent or covalent interaction with the hydrophobic part of the molecule or electrostatic interaction. The hydrophilic part of the molecule serves as the anchoring site for surface modification of the electrode active material. The redox potential of the molecule is close to the redox potential of the electrode active material. The adsorbed assembly of redox-molecule & SWCNT thus improves the charge transfer from a current collector to the electrode active material.

Abstract: This invention concerns a lithium rechargeable electrochemical cell containing electrochemical redox active compounds in the electrolyte. The cell is composed of two compartments, where the cathodic compartment comprises a cathodic lithium insertion material and one or more of p-type redox active compound(s) in the electrolyte; the anodic compartment comprises an anodic lithium insertion material and one or more of n-type redox active compound(s) in the electrolyte. These two compartments are separated by a separator and the redox active compounds are confined only in each compartment. Such a rechargeable electrochemical cell is suitable for high energy density applications. The present invention also concerns the general use of redox active compounds and electrochemically addressable electrode systems containing similar components which are suitable for use in the electrochemical cell.

Abstract: For producing photocatalytically active polymer surfaces, a method is indicated by which particles of the photocatalytically active oxidic material are accelerated by a carrier gas, when impacting on the polymer surface, partially penetrate into the polymer and, as a result of their high kinetic energy, form a mechanically firmly adhering polymer/oxide bond.
