Abstract: Measuring access rates of a computer memory include subdividing the memory into subsections, monitoring access rates for each of the subsections, in response to a subsection having a relatively high access rate, subdividing the subsection into multiple subsections that are separately monitored, and, in response to at least two adjacent subsections having a relatively low access rate, merging the at least two subsections into a single subsection. Monitoring access rates may include monitoring at least one of the following operational parameters: number of data accesses, number of cache accesses, number of cache misses, number of read accesses, number of write accesses, and ratio of read accesses to write accesses. Two or more operational parameters may be used and the operational parameters may be weighted.

Abstract: The invention comprises an array of ADCs, associated either with spatially separated signal input devices such as for example antennae, or with a single signal input device and a plurality of filters having a variable phase delay, which provide a digital output which is processed to remove spurious signals introduced by the ADCs thereby providing a linearised output. An array of N antennae with respective band pass filters and ADCs (10) feeds received signals into a frequency channelisation device (12) which divides each of the N input streams into M lower bandwidth streams for distribution. In a first path, an FFT (14) is used to detect signal of interest, to determine where intermodulation products arm likely to exist and to provide course data for the spatial processing used in the signal separation sub-systems. The second path (16) includes the detection and separation of co-channels signals. Signal classification techniques are then used to identify spurious sir, which are then removed.

Abstract: A method for modulating plant growth is provided whereby seedlings that are grown in containers such as blocks are fertilized at lift. Prior to fertilization, the block, which has numerous plug cavities, is restrained. The seedlings, which are grown in plugs formed in plug cavities, are supported and a bore is drilled into the bottom of the plug. The bore extends to the top of the plug to produce a small port, which serves as a port for expulsion of air during the injection operation. The fertilizer is measured in a metering roller and is then pneumatically injected into the bore in the plug. Upon completion of the injection, the bore is closed to reduce the loss of fertilizer from the plug. The various operations may be automated or performed manually.

Abstract: A drill/injector combination is provided to inject plants that are grown in containers such as blocks at lift with plant growth modulators. The drill/injector combination is comprised of a seedlings holder, a block restraint, a cavity tool apparatus, a metering apparatus, an injection apparatus and optionally, a bore closing apparatus. The combination may be manually operated or may be automated.
