  • Publication number: 20210141538
    Abstract: Volume deployment is optimized while adopting layering corresponding to IO density is adopted. A storage management apparatus calculates remaining IO density based on an amount of remaining IOPS and an amount of a remaining capacity in IOPS and a capacity that are providable by a node, the remaining IOPS and the remaining capacity being not allocated to any volume, controls the layers of the node based on the remaining IO density, selects a node on which a volume is to be deployed based on the difference between the IO density of a deployment target volume and the remaining IO density of the node, and determines a node having the smallest difference between the IO density of the deployment target volume and the remaining IO density of the node in the selection of the node as a deployment destination of the volume.

  • Publication number: 20130037479
    Abstract: It is an object of the present invention to provide a hollow fiber forward osmosis membrane, which can enhance forward osmotic pressure energy acquired by permeation, and thus improve power generation efficiency in the forward osmotic pressure power generation, when dilution water such as freshwater permeates into seawater through the osmosis membrane. The relationship between optimal conditions for an inner diameter d and a length L of the hollow fiber osmosis membrane to be used for forward osmotic pressure power generation whereby dilution water such as fresh water is caused to permeate into non-concentrate seawater through the hollow fiber osmosis membrane to increase a flow rate on the side of the seawater using forward osmotic pressure energy thus generated, and power is generated using the increased flow rate, is expressed as equation (1) in the range of d=50 to 200 ?m, L=0.5 to 2 m and J=1.7×10?7 to 5.1×10?7 m/sec, [Equation 11] d L 0.75 + J 0.5 = 1.0 × 10 5 ? 1.

  • Patent number: 7583307
    Abstract: In a stereoscopic display system, comprising a display and a lens array, it is difficult to manufacture the lens array with lens spacing at high accuracy as designed, and it is also difficult to attain high installation accuracy when the display and the lens array are combined together. An image of a stereoscopic display 27 with a display 1 and a lens array 2 integrated with each other is taken by a camera 3, and a positional relation of each pixel of the display 1 and each lens center of the lens array 2 is determined by a measuring system 4. Based on the matching positional relation information of the lenses and the pixels thus acquired, a stereoscopic image generating/outputting system 12 generates a stereoscopic image and supplies the image to the stereoscopic display 27.
