Modeling and animation of facial expressions based on B-Splines

This paper describes a technique for the automatic adaptation of a canonical facial model to data obtained by a 3D laser scanner. The facial model is a B-spline surface with 13×16 control points. We introduce a technique by which this canonical model is fit to the scanned data and that takes into consideration the requirements for the animation of facial expressions. The animation of facial expressions is based on the facial action coding system (FACS). Using B-splines in combination with FACS, we automatically create the impression of a moving skin. To increase the realism of the animation we map textural information onto the B-spline surface.     

Relationship between age and risk taking among managers.

Administered a short version of N. Kogan and M. Wallach's (see pa, vol. 39:6826) choice-dilemma test to 1,484 managers from over 200 companies. Results show a significant negative relationship between age and both risk taking and the value placed upon risk. The relationships were small in size when individual scores were correlated with age, but increased markedly when mean scores were used. Furthermore, the relationships were relatively stable across items and across companies. Developmental and sociocultural mechanisms that might underlie these findings are discussed.

L x-ray satellite energies

Theoretical energies are tabulated for the L x-ray satellites that arise from electric dipole and quadrupole transitions in the presence of one spectator hole in the M- or N-shell. Results are listed for 11 elements with atomic numbers 65 ≤ Z ≤ 95. The computations are relativistic and include quantum-electrodynamic corrections. Subsidiary tables list the Coulomb and Breit interaction energies for double-hole states and the relative x-ray intensities of double-hole multiplet states.     

Static and Dynamic Mechanical Behavior of Electron Beam‐Cured Monomer and Monomer/Liquid Crystal Systems

Summary: This paper discusses static and dynamic mechanical properties of electron beam‐cured mixtures made of the nematic liquid crystal (LC) E7 and either tripropyleneglycol diacrylate (TPGDA) or propoxylated glycerol triacrylate (GPTA) as monomers differing essentially by their functionality. Dilution of the initial mixture with LC leads to a significant weakening of the film mechanical strength. Strong effects were found on Young modulus and rubbery state modulus. As the concentration of LC increases, these mechanical parameters drop significantly together with the glass transition temperature of the polymer showing a plasticizing effect. The results for the glass transition temperatures for the polymer and the LC were confirmed by thermograms obtained by differential scanning calorimetry.
