3D human motion analysis system is gaining more and more popularity and importance in sports training, game simulation and many other areas. Particle filter algorithm, as a powerful optimized method, can be applied to 3D human motion analysis system with more accurate results delivered and assured. An improved (hybrid) particle filter algorithm (IPFA) is proposed in this paper which integrates the advantages of partitioned particle filter algorithm (PPFA) with annealed particle filter algorithm (APFA). The results show that, the hybrid algorithm (IPFA) gives rise to more accurate results with less computational time consumed, compared to PPFA and APFA, and improves tracking efficiency and accuracy of 3D human motion substantially.

A soluble, but nontrivial, model of a dilute Ising ferromagnet is studied, with infinite-range in- teractions but finite average connectivity c. The density of (Yang-Lee) zeros of the partition func- tion in the complex z=exp(-2H) plane (where H is the external magnetic field in units of the tem- perature) is calculated explicitly in the high-temperature phase for large but finite c and small ]H]. The density of zeros on the unit circle H=iO has the form p(θ)～exp{-[cf(K)/]θ]ln( 1/[θ]for [01 >0. The function f(K) (K=J/73 vanishes at the critical coupling Kc(c). Heuristic arguments are given for the form of p(θ) expected for systems with short-range interactions.

e, fcc solid solution: we have taken Ni3Al and a Au solute in copper as examples of these systems. Many-body interatomic potentials for these alloys have been used, but modified at small separations to provide suitable descriptions of collisions at near-threshold energies. The properties of point defects associated with a single Au solute atom in a copper matrix are presented, and it is then shown that the threshold energy, Ed, for the Au recoil in this alloy is smaller and has much less orientation-dependence than is found for a Cu recoil in the pure metal. This effect is related to the number of atoms temporarily displaced from their sites during the creation of a stable Frenkel pair. Ed for Al in Ni3Al is much higher than in pure aluminium and similar in size to that of a Ni atom. The stable defect arrangements produced at threshold are in general much more complex than for pure metals, and defects on the Ni sublattices are usually the majority species. A striking effect occurs for 110 recoils along mixed Ni-Al-Ni-Al- … rows, for chains of antisite defects created by replacement sequences break to form two Frenkel pairs for each primary recoil atom.

On the basis of a new physical picture universally valid for all condensed matter of the infrared-divergence theory and starting from a non-Markovian process, the author investigates electronic excited-state or exciton transfer in disordered systems. The obtained results indicate that the present picture, which differs from the traditional Markovian-transport picture, is more reasonable and more universal than other existing theories. The theoretical predictions are in good agreement with the experimental investigation.
