Abstract Let $M \subset X$ be a submanifold of rational homogeneous space $X$ such that the normal sequence splits. We prove $M$ is also homogeneous.

We characterize all (n?2)-dimensional linear subspaces of Pn such that the induced projection, when restricted to rational normal curve, gives a Galois morphism. give an explicit description these spaces as disjoint union locally closed subvarieties in Grassmannian G(n?2,n).

OBJECTIVE We employ a nasal tip finite element model (FEM) to evaluate contributions of two of the three major tip support mechanisms: attachments between the upper and lower lateral cartilages and attachment of the medial crura to the caudal septum. STUDY DESIGN The nasal tip FEM computed stress distribution and strain energy density (SED) during nasal tip compression. We examined the impact...

Thi~ paper is baaed on the working principle of scroll compressor and after investigating the ga~ flow condition, in especial analysis the gas leaking situation between two scroll parts mutual gearing, which influence the compressor performance very much. The working process calculating model is set up, employ the soroll compressor geometric parameter, size~ error of parts manufactured as well ...

An 11 kW R410A heat pump system with a two-stage vapor-injected scroll compressor has been developed and tested. A conventional heat pump system with a scroll compressor having the same displacement volume to the vapor-injected scroll compressor has been tested under the same conditions to serve as a baseline. The vaporinjected scroll compressor has been tested with the cycle options of both fl...

In this paper, the motion control of a mobile robot, which is based on a specific type of chaotic systems, is studied. These systems produce the well-known from the nonlinear theory double-scroll chaotic attractors. So, the proposed motion control strategy of the mobile robot is based on a chaotic path planning generator in order to cover a terrain fast and with unpredictable way. For choosing ...
