Abstract: A composite steel plate includes at least two steel sheets rolled to form a plate. One of the sheets has a composition that varies in a depthwise direction, between nanocrystalline and micron grained. The plate is made by treating a steel sheet to produce a composition in the sheet that varies in a depthwise direction of the sheet between nanocrystalline and micron grained, stacking the treated sheet with at least one other steel sheets and rolling the stacked sheets to form the plate.

Abstract: To use the memory space more effectively, cell memory can be shared by an input link and all output links. To prevent one flow from occupying the entire memory space, a threshold may be provided for the queue. The queue threshold may accommodate the RTT delay of the link. Queue length information about a downstream switch module may be sent to an upstream switch module via cell headers in every credit update period per link. Cell and/or credit loss may be recovered from. Increasing the credit update period reduces the cell header bandwidth but doesn't degrade performance significantly. Sending a credit per link simplifies implementation and eliminates interference between other links.
Abstract: The present invention relates to an energy-saving system for three-phase induction motors and is based on the principle of variable voltage control at constant speed. It is composed of a microprocessor, exampling circuit, sensing circuit, acquiring circuit, firing circuit, and AC to AC converter. The system is to automatically adjust the voltage to the induction motor with the variation in the motor load, in order to obtain high operating power factor and efficiency. The system will result in considerable energy-savings when a three-phase induction motor runs under constant light-load or variable-load with low duty ratio.

Abstract: This invention involves fabric-supported chitosan modified temperature responsive PNIPAAm/PU hydrogel and the use thereof in preparation of facial mask. The merit of this invention is the hydrogel formed can reversibly swell and deswell near body temperature; the incorporation of PU can suppress the syneresis of PNIPAAm at an elevated temperature; Grafting of PNIPAAm and PU onto the surface of cellulose fabrics can enhance the mechanical strength of hydrogel; Coupling of chitosan to the surface of hydrogel can not only improve the handle and skin affinity, but also render the facial mask antibacterial; The hydrogel is capable of loading a variety of nutrients (or other functional components), which can release at body temperature; the hydrogel facial mask can be reusable with repeated rinsing.
Abstract: A system for automatically controlling power supply to a lamp (101) of a vehicle, the system comprising: a detection module (20) to detect whether the vehicle is stationary or non-stationary; a controller (102) to receive a signal (25) having a first value transmitted by the detection module (20) when the vehicle is detected as stationary, and the controller (102) to receive a signal (25) having a second value transmitted by the detection module (20) when the vehicle is detected as non-stationary, wherein if the signal (20) having the first value is received by the controller (102), the controller (102) reduces the power supply to the lamp (101) from a first power level to a lower second power level in order to reduce energy consumption of the lamp (101), and if the signal (25) having the second value is received by the controller (102), the controller (102) restores the power supply to the lamp (101) from the lower second power level to the first power level.

Abstract: An magnetorheological damper useful in structural vibration control has a damper body and a moveable portion relative to the damper body. The damper includes an magnetorheological material contained within the damper body for resisting movement of the moveable portion. Rheology changes can be generated in the magnetorheological material owing to changes in a magnetic field, to which the magnetorheological material is exposed. The damper further includes at least a sensor embedded in the damper for monitoring an external force exerted on the damper, and for generating a signal to control the magnetic field and hence the resulting yield force and rheological damping of the damper in response to a variance in the external force.
Abstract: Packets out-of-sequence problem can be solved by using a window flow control scheme that can dispatch traffic at the cell level, in a round robin fashion, as evenly as possible. Each VOQ at the input port has a sequence head pointer that is used to assign sequence numbers (SN) to the cells. Also a sequence tail pointer is available at each VOQ that is used to acknowledge and limit the amount of cells that can be sent to the output ports based on the window size of the scheme. Each VIQ at the output port has a sequence pointer or sequence number (SN) pointer that indicates to the VIQ which cell to wait for. Once the VIQ receives the cell that the SN pointer indicated, the output port sends an ACK packet back to the input port. By using sequence numbers and the relevant pointers, the packet out-of-sequence problem is solved.
Abstract: A sequence online analytical processing (S-OLAP) system 50 for analysing an event database (41) storing events (12), the system (50) comprising: an S-OLAP engine (53) to compute an S-cuboid (49) for a query on the event database (41); a sequence query engine (54) to form part of the S-cuboid (49) by performing the steps of: selection, clustering, sequence formation and sequence grouping; a cuboid repository (52) to store computed S-cuboids (49) and to be searched by the S-OLAP engine (53) for an S-cuboid query to determine whether an S-cuboid has previously been computed; and a sequence cache (56) to cache constructed sequence groups.

Abstract: Amphiphilic, magnetic composite particles are comprised of cores and shells. The core contains both hydrophobic vinylic graft copolymer, hydrophobic vinylic homopolymer and magnetic nanoparticles, and the shell to which the hydrophobic vinylic polymer is grafted is a hydrophilic, nitrogen-containing polymer. Typically, the composite particles are made by a process which involves generating radicals on nitrogen atoms of the water-soluble polymer, and then initiating free-radical copolymerization of said vinylic monomer(s) and vinylic-coated magnetic nanoparticles, whereby vinylic polymer(s) undergo(es) phase separation and the vinylic coated magnetic nanoparticles are encapsulated within the vinylic polymer to form a composite latex.
