‎Let $M^n$ be an $n(ngeq 3)$-dimensional complete connected and‎ ‎oriented spacelike hypersurface in a de Sitter space or an anti-de‎ ‎Sitter space‎, ‎$S$ and $K$ be the squared norm of the second‎ ‎fundamental form and Gauss-Kronecker curvature of $M^n$‎. ‎If $S$ or‎ ‎$K$ is constant‎, ‎nonzero and $M^n$ has two distinct principal‎ ‎curvatures one of which is simple‎, ‎we obtain some‎ ‎charact...

One of the great challenges of putting humanoid robots into space is developing cognitive capabilities for the robots with an interface that allows human astronauts to collaborate with the robots as naturally and efficiently as they would with other astronauts. In this joint effort with NASA and the entire Robonaut team we are integrating natural language and gesture understanding, spatial reas...

in laboratory experiments the toxicity of acetone was investigated against four species of stored-product insects. in empty-space trials, estimates of the lethal concentrations of acetone (lc, 72-h exposure) for 50% mortality against adults of the lesser grain borer, rhizopertha dominica (f.), red flour beetle, tribolium castaneum (herbst), rice weevil, si-tophilus oryzae (l.) and eggs of the a...

let (x, d) be a compact metric space and f : x → x be a continuous map. consider the metric space (k(x),h) of all non empty compact subsets of x endowed with the hausdorff metric induced by d. let ¯ f : k(x) → k(x) be defined by ¯ f(a) = {f(a) : a ∈ a} . we show that block-coppels chaos in f implies block-coppels chaos in ¯ f if f is a bijection.

A review on spectral and differential-geometric properties of Delsarte transmutation operators in multidimension is given. Their differential geometrical and topological structure in multidimension is analyzed, the relationships with De Rham-Hodge-Skrypnik theory of generalized differential complexes are stated. Some applications to integrable dynamical systems theory in multidimension are pres...

H.264/AVC has been designed particularly to improve coding efficiency and network friendliness. In this paper, a simulator and profiler tool set based on the SimpleScalar framework [1] is developed to derive instruction level complexity of the H.264/AVC codec [2]. The reference software JM8.6 is analyzed. Arithmetic, logic, shift, control operations and memory bandwidth requirements for the ful...

Employing the construction method of Dirichlet forms on standard forms of von Neu-mann algebras developed in Pa], we construct Dirichlet forms and associated symmetric Markovian semigroups on CCR algebras with respect to quasi-free states. More precisely, let A(h 0) be the CCR algebra over a complex separable pre-Hilbert space h 0 and let ! be a quasi-free state on A(h 0). For any normalized ad...

Der Globefish sowie die Globemouse sind zwei an der BauhausUniversität Weimar entwickelte Eingabegeräte, welche jeweils sechs Freiheitsgrade (degree of freedom, DOF) besitzen. Das heißt, man kann damit die Rotation eines Objekts sowie seine Verschiebung im dreidimensionalen Raum steuern. Im Folgenden sollen nun die in [2] vorgestellten Geräte und Versuchsergebnisse zusammenfassend betrachtet we...

Let G be a countably infinite group and (X,μ) a standard non-atomic probability space. We denote by A(G,X, μ) the space of measure preserving actions of G on (X,μ) with the weak topology. If a,b ∈ A(G,X, μ), we say that a is weakly contained in b, in symbols a b, if a is in the closure of the set of isomorphic copies of b (i.e., it is in the closure of the orbit of b under the action of the aut...
