A hybrid LUN copy operation that ultimately produces a full LUN copy, but involves a transient snapshot-copy-like intermediate stage. In one embodiment, a statically pre-allocated copy LUN is initialized with references pointing back to the primary LUN. Over time, the sectors, blocks, or other data-storage units of the primary LUN are copied to the copy LUN, so that, in the end, a full copy LUN in completed. In a second, alternative embodiment, both the primary LUN and copy LUN are READ and WRITE accessible immediately following the nearly instantaneous initialization of the copy LUN. In both embodiments, the copy LUN may be statically allocated. The immediate-full-LUN-copy operations provided by the present invention further enable rotatable copy-LUN groups, each copy LUN within a copy-LUN group representing a full, robust copy LUN.

A duplexer has an asymmetrical antenna port and a symmetrical reception output, and therefore can be interconnected (without any intermediate stages) to an amplifier with a differential input. A reception bandpass filter is arranged in the reception path of the duplexer. The reception bandpass filter can have the functionality of a balun. The transmission input of the duplexer can be designed symmetrically, in which case a transmission bandpass filter arranged in the transmission path should be designed symmetrically on the input side. The impedance of the antenna port of the duplexer can differ from the impedance of the reception output or the transmission input. No intermediate stages (such as a balun or—in cases of impedances that differ between the duplexer and its corresponding amplifier—an impedance transformer) are required between the duplexer and the amplifier that is interconnected (whether before or after) in the transmission or reception path.

A cascaded MZI-TDC arrangement with also only a single control is formed by cascading two MZI-TDC arrangements and driving all adjustable couplers with the same control signal.

A method and apparatus for partitioning a data set for clustering, based on the physical properties of an inhomogeneous ferromagnet. No assumption is made regarding the underlying distribution of the data. A Potts spin is assigned to each data point and an interaction between neighboring points is introduced, whose strength is a decreasing function of the distance between the neighbors. This magnetic system exhibits three phases. At very low temperatures it is completely ordered; i.e. all spins are aligned. At very high temperatures the system does not exhibit any ordering and in an intermediate regime clusters of relatively strongly coupled spins become ordered, whereas different clusters remain uncorrelated. This intermediate phase is identified by a jump in the order parameters. The spin-spin correlation function is used to partition the spins and the corresponding data points into clusters.

The process involves producing an aluminum alloy sheet product by direct chill casting an aluminum alloy to form a cast ingot, homogenizing the ingot, hot rolling the ingot to form and intermediate gauge product, cold rolling the intermediate gauge product to form a product of final gauge, and subjecting the final gauge product to a solutionizing treatment by heating the product to a solutionizing temperature, followed by a pre-aging step involving cooling the product to a coiling temperature above 50 DEG C., coiling the cooled product at the coiling temperature, and cooling the coiled final gauge product from the coiling temperature above 50 DEG C. to ambient temperature at a rate less than about 10 DEG C. per hour to improve T8X temper characteristics of the product. Additionally, a batch anneal step is carried out on the intermediate gauge product or at an intermediate stage of the cold rolling to reduce or eliminate roping tendencies of the alloy sheet product. To maintain a high T8X response, the alloy used in the process has the following composition: 0.4 to 1.1% by weight magnesium; 0.3 to 1.4% by weight silicon; 0 to 1.0% by weight copper; 0 to 0.4% by weight iron; 0 to 0.15% by weight manganese; 0 to 0.15% weight naturally-occurring impurities (collective total); and the balance aluminum.
