    • A feature vector computation section 24 of an image processing apparatus computes a feature vector expressing gradient histograms for each of plural child regions that have been further partitioned from plural parent regions partitioned from a discrimination-subject image. A feature relative vector computation section 26 of the image processing apparatus computes for each parent region a feature relative vector expressing relative values computed from respective combinations of the same or different elements across feature vectors computed for each child region, and relative values computed from respective combinations of the same or different elements within one of the feature vectors. A discrimination section 30 of the image processing apparatus, based on the feature relative vector computed for each parent region, discriminates whether or not the image subject to processing is an image in which a processing target object appears.

    • A method, system and apparatus are disclosed for conducting a reservoir simulation, using a reservoir model of a gridded region of interest. The grid of the region of interest includes one or more types of cells, the type of cell being distinguished by the number of unknown variables representing properties of the cells. The cells share a common variable as an unknown variable. The method includes the steps of identifying different cell types for the grid; constructing an overall matrix for the reservoir model based on the different cell types; at least partially decoupling the common variable from the other unknown variables in the matrix by using a reduction process to yield a reduced matrix; mathematically breaking up the variables in the reduced matrix into k subsets by cell types; applying an overlapping multiplicative Schwartz procedure to the reduced matrix to obtain a preconditioner and using the preconditioner to solve for the unknown variables.

    • A light emitting device made of semiconducting materials. The device has an optical microcavity which supports a resonant mode of predetermined photon energy. Within the cavity is a quantum well of predetermined thickness and energy depth. The quantum well is designed such that it forms bound electron, exciton, lower polariton, and hole energy states of predetermined energy. The energy of an exciton state is set to equal the predetermined photon energy of the microcavity mode such that polariton states are created. A means is provided for resonantly tunneling electrons into a quantum well energy state. In a first embodiment, electrons resonantly tunnel into an electron energy state. In a second embodiment, electrons resonantly tunnel into an exciton energy state, during which tunneling the electrons simultaneously fuse with holes to form excitons. In the first embodiment, the electron state to lower polariton state transition energy is made equal to the energy of a longitudinal optical (LO) phonon of the quantum well material. This energy equivalence facilitates the rapid thermalization of resonantly tunneled electrons to combine with holes and form polaritons resonant with the cavity mode. Thermalization is rapid because it only requires the scattering of a single LO phonon. The photon component of the polariton is then emitted through the leaky cavity reflector. The second embodiment sets the exciton to polariton transition energy equal to the LO phonon energy to facilitate rapid thermalization to the polariton state. Photons are then emitted through the leaky Bragg reflector in the same manner as the first embodiment.
    • 由半导体材料制成的发光器件。 该器件具有支持预定光子能量的共振模式的光学微腔。 在腔内是一个预定厚度和能量深度的量子阱。 量子阱被设计成使其形成结合的电子,激子,低极化子和预定能量的空穴能态。 将激子状态的能量设定为等于微腔模式的预定光子能量,从而产生极化子态。 提供了一种用于将电子谐振地隧穿到量子阱能量状态的装置。 在第一实施例中,电子谐振地隧穿成电子能态。 在第二个实施例中,电子谐振地隧道入激子能态,在此期间,电子同时与空穴一起熔化以形成激子。 在第一实施例中,将使极性较小的跃迁能量降低的电子状态等于量子阱材料的纵向光学(LO)声子的能量。 这种能量等价有助于谐振隧穿电子的快速热化与空穴结合并形成与腔模共振的极化子。 热化是快速的,因为它只需要单个LO声子的散射。 然后通过泄漏腔反射器发射极化子的光子分量。 第二实施例将激子设置为等于LO声子能量的极化子跃迁能量,以促进快速热化至极化子态。 然后以与第一实施例相同的方式通过漏布拉格反射器发射光子。
