Abstract:
One embodiment of the present invention provides a method for fabricating a highly reflective electrode in a light-emitting device. During the fabrication process, a multilayer semiconductor structure is fabricated on a growth substrate, wherein the multilayer semiconductor structure includes a first doped semiconductor layer, a second doped semiconductor layer, and/or a multi-quantum-wells (MQW) active layer. The method further includes the followings operations: forming a contact-assist metal layer on the first doped semiconductor layer, annealing the multilayer structure to activate the first doped semiconductor layer, removing the contact-assist metal layer, forming a reflective ohmic-contact metal layer on the first doped semiconductor layer, forming a bonding layer coupled to the reflective ohmic-contact metal layer, bonding the multilayer structure to a conductive substrate, removing the growth substrate, forming a first electrode coupled to the conductive substrate, and forming a second electrode on the second doped semiconductor layer.
Abstract:
A patterned dielectric elastomer actuator is disclosed which includes a series of thin parallel elastomer filaments, separated by certain distances sandwiched between a pair of rigid electrodes. The elastomer filaments and air acts as a patterned dielectric layer. The elastomer filaments can compress laterally from a circular cross-section to an elliptical shape when a voltage is applied between the rigid electrodes. The elastomer filaments can touch laterally, which implies no further squeezing in order to provide a minimal secure distance between the rigid electrodes. The dielectric elastomer actuator can be fabricated utilizing a reel-to-reel fabrication process with the thin elastomer filaments fabricated ahead of time, by extrusion techniques and cured completely before storing on reels.

A low profile semiconductor package is disclosed including at least first and second stacked semiconductor die mounted to a substrate. The first semiconductor die may be electrically coupled to the substrate with a plurality of stitches in a forward ball bonding process. The second semiconductor die may in turn be electrically coupled to the first semiconductor die using a second set of stitches bonded between the die bond pads of the first and second semiconductor die. The second set of stitches may each include a lead end having a stitch ball that is bonded to the bond pads of the second semiconductor die. The tail end of each stitch in the second set of stitches may be wedge bonded directly to lead end of a stitch in the first set of stitches.

A system, a computer device implemented method, and a computer readable article of manufacture for executing a computer implemented method for a unified access control for a plurality of composed services in a distributed computing environment without requiring repeated input of security certification. The method includes the steps of: acquiring a first role of a user in a first composed service; sending an invoking request by a processing unit of the first composed service to a second composed service; receiving the first role of the user in the first composed service and predefined role-role mapping relationships, and determining a second role of the user in the second composed service by a role determining component; and then sending the determined role in the second composed service by a role sending component to the second composed service, thereby providing unified access without requiring repeated input of security certification.
Abstract:
A method, system and computer program product are disclosed for matching virtual currency exchange requests. The method comprises the step of creating a virtual currency exchange network comprised of a set of nodes and a set of edges connecting the nodes together. Each of the nodes represents a virtual currency type, each of the edges represents a virtual currency exchange request, and one of the edges represents a current virtual currency exchange request. A plurality of paths are identified in the network as potentially fulfilling the current virtual currency exchange request. Each of these paths is comprised of at least two edges of the network, and each of the paths represents one way to fulfill the current virtual currency exchange request. One of those paths is selected, using a defined set of criteria, as an optimal path for fulfilling said current virtual currency exchange request.
Abstract:
The invention relates to a kind of fly ash heat preservation board. It is made of mixed foam slurry and stuff solid in the mould. Main materials of the stuff include light burring magnesium powder, magnesium chloride solution, fly ash, oxalic acid and glass fiber. Proportion of main materials of the above-mentioned stuff is: fly ash 200 portions, light burning magnesium powder 100-150 portions, oxalic acid 1-2 portions, glass fiber 5-15 portions. Wherein said magnesium chloride is 28-32 Degree Baum'e magnesium chloride water solution, the addition quantity is 40-75 portions. Wherein said vesicant is animal protein vesicant, foam diameter should be controlled between 0.1˜1 mm, it can be maintained naturally after being mounded. The invention improve anti-pressure intensity of board, which benefits for increasing foam quantity, lowing board density and improving heat preservation performance.
Abstract:
Increased yields of naphtha and increased catalyst activity are obtained in a hydrocracking process by the use of a catalyst containing a beta zeolite and a Y zeolite having a unit cell size from 24.38 to 24.50 angstrom. The catalyst has a relatively high amount of Y zeolite relative to beta zeolite.

Abstract:
The cloning of a novel PCVII viral genome is described as is expression of proteins derived from the PCVII genome. These proteins can be used in vaccine compositions for the prevention and treatment of PCVII infections, as well as in diagnostic methods for determining the presence of PCVII infections in a vertebrate subject. Polynucleotides derived from the viral genome can be used as diagnostic primers and probes.
Abstract:
A method of modelling an object (313), comprising capturing images of the object from a plurality of spaced apart cameras (310), creating a three-dimensional model (31) of the object from the images and determining from the model and the images a lighting model (36) describing how the object is lit. Typically, the method comprises the step of estimating the appearance of the object if it were evenly lit; and minimising the entropy in the estimated appearance of the object. Similarly, also disclosed is a method of determining how a two-dimensional image is lit, comprising capturing the image (21), modelling the lighting of the image and removing the effects of the lighting, in which the method comprises calculating the entropy of the image with the effects of the lighting removed and selecting the model such that the entropy is minimised.
