    摘要: A redundant disk array method includes allocating identically sized logical blocks of storage units together to form a stripe on each of several data storage devices, at least two of the logical blocks in the stripe being located on different data storage devices, generating a lookup table representing a mapping between a logical location of each logical block in the stripe and a physical location of the respective logical block on the corresponding data storage device, and electronically writing data to the physical locations of each logical block in the stripe, the physical locations being obtained from the lookup table. In some cases, at least two of the data storage devices are heterogeneous, and at least two of the data storage devices have a different total number of logical blocks.

    摘要: A system for the compression and decompression of image files is provided. A library of basic waveforms is produced by applying selected digital initialization codes to a chaotic system. Each basic waveform is in one-to-one correspondence with an initialization code. A weighted sum of selected basic waveforms is used to approximate each slice of an image. The basic waveforms are then discarded and only the weighting factors and the corresponding initialization codes are stored in a compressed image file. When the compressed image file is decompressed for playback, the stored initialization codes are stripped out and applied to a similar chaotic system to regenerate the basic waveforms, which are recombined according to the stored weighting factors to produce an approximation of the original image slice.

    摘要: An auxetic polygonal cell may have a plurality of chiral structures capable of rotation. The plurality of chiral structures may at least partially enclose a volume. Each of the chiral structures may include a first cross member having a first set of distal ends and a second cross member intersecting the first cross member, the second cross member having a second set of distal ends. The chiral structures may also include a first set of legs, wherein each leg of the first set of legs extends from at least one distal end of the first set of distal ends and a second set of legs, wherein each leg of the second set of legs extends from at least one distal end of the second set of distal ends.

    摘要: Solar cells fabricated from p-n junctions of boron nitride nanotubes alloyed with carbon are described. Band gaps of boron nitride carbon alloys are tailored by controlling carbon content in the boron nitride nanotubes. High efficiency solar cells can be fabricated by tailoring the band gap of boron nitride carbon alloy nanotubes, and using these nanotubes for fabricating solar cells u. Because boron nitride carbon alloy nanotubes are transparent to most wavelengths of light, the wavelengths not converted to electrons (i.e., absorbed) at a first p-n junction in a solar cell will pass through the stack to another p-n junction in the stack having a different band gap. At each successive p-n junction, each of which has a different band gap from the other p-n junctions in the stack, more wavelengths of light will be converted into electricity. This dramatically increases the efficiency of solar cells.

    摘要: This disclosure is generally directed to a microstrip phased array antenna with a switch line phase shifter to obtain steerable beam pattern. In an embodiment, the microstrip phased array antenna includes a plurality microstrip lines disposed/patterned on a substrate to form a relatively compact phase shifter network that can switchably introduce phase shifts into an RF signal. In particular, each phase shifter of the phase shifter network may be formed from a number of equal-length RF lines that extend from a common point and “loop” to form substantially circular paths. The common point from which each of the RF lines extend may include a VIA to couple to an antenna device. A plurality of switches, e.g., PIN diodes, may be disposed along the RF lines to switchably extend the overall length of each of the phase shifters, and more particularly each transmission line, to selectively introduce a target phase shift.

    摘要: A magnetic confinement system includes a magnetic minor device that includes a chamber to hold a target plasma and a coil arrangement to generate a magnetic field configuration in the chamber to confine the target plasma in cylindrically-symmetric form in the chamber, the magnetic field configuration having open ends. The magnetic confinement system further includes plasma guns to generate plasma pistons and project the plasma pistons at the open ends of the magnetic field configuration. In operation, the plasma pistons converge towards each other to close the open ends of the magnetic field configuration and to compress and heat the target plasma.
