Abstract: A dry mixture for use with water has been developed to be used as an erosion control spray matrix for reducing erosion of sandy soils while awaiting development of a root system of plants to hold the soil in place. The dry erosion control mixture includes alpha-calcined calcium sulfate hemihydrate, a non-gypsum binder polymer; biodegradable fibers; and wood fiber mulch. An erosion control slurry is applied to an area of soil in need of erosion-control. After obtaining the dry erosion control mixture, it is mixed with water to form erosion control slurry. The ratio of the composition to the water is preferably from about 1:8 to about 1:12. Seed is distributed over the soil and the erosion control slurry is applied over the distributed seed.
Abstract: A virtual-machine control program includes an operational-status inquiry unit that inquires of another machine about a memory usage status of virtual machines realized on another machine; a swapping-target selecting unit that selects a virtual machine capable of being swapped for a virtual machine realized on a machine from among the virtual machines realized on another machine based on information obtained by the operational-status inquiry unit; and a swapping performing unit that swaps the virtual machine realized on the machine for the virtual machine selected by the swapping-target selecting unit. The virtual-machine control program enables to move the virtual machine to another machine without preparing a free space in advance.

Abstract: A method and an apparatus are described for determining parameters of a contact between bodies occurring within an activity. A digital camera directed towards a target area during the activity captures image frames including infra red image data. Structure for comparing image data for multiple temporally spaced frames with image data of a reference datum records any localized infra red emission appearing in at least one incident frame. The image data for at least one of the incident frames is analyzed to determine at least one parameter of the contact, and the image data for the incident frame is recorded. Visual display means displays the incident frames including the image data in the IR spectrum to enable visual inspection of the activity in the target area at the time of the incident frame and that gave rise to the contact producing the infra red emission.
Abstract: An error addition apparatus receives a data signal D having a frame format having a specific signal inserted into its front, adds errors to the data signal D, and outputs a resulting signal. The apparatus has an error addition regulation unit for receiving a frame synchronization signal F, indicative of a timing at which the front of the frame of the data signal has been inputted, and regulating the errors such that the errors are added to positions other than a region of the specific signal. Accordingly, errors are not added to a specific signal.

Abstract: A tracking device for automatically following a moving light source that is detectable in the presence of ambient light. A carrier platform including one or more radiant energy conversion devices and a sensor array is mounted to an upright support column with a universal joint. Three linear actuators, each having an associated light sensor, are equally angularly spaced about the support column with an upper end connected to the carrier platform with a universal hinge and a lower end connected to a floating base with a spherical hinge. The floating base is free to move axially but not radially of the support column. The actuator of a light sensor receiving a lesser amount of radiant energy retracts, and extends when receiving a greater amount of radiant energy. Each light sensor is moved in a stepwise manner, with a predetermined, limited number of steps used to define light source acquisition for tracking purposes.
Abstract: The present invention reports a defect that has not been reported, and discloses a defect-controlled silicon ingot, a defect-controlled wafer, and a process and apparatus for manufacturing the same. The new defect is a crystal defect generated when a screw dislocation caused by a HMCZ (Horizontal Magnetic Czochralski) method applying a strong horizontal magnetic field develops into a jogged screw dislocation and propagates to form a cross slip during thermal process wherein a crystal is cooled. The present invention changes the shape and structure of an upper heat shield structure arranged between a heater and an ingot above a silicon melt, and controls initial conditions or operation conditions of a silicon single crystalline ingot growth process to reduce a screw dislocation caused by a strong horizontal magnetic field and prevent the screw dislocation from propagating into a cross slip.

Abstract: To perform image correction according to the features of an input image and output a fine and conspicuous image corresponding to a variety of scenes; an image correcting apparatus detects, from the pixels of the input image, the dark pixels that have the respective pixel values equal to or smaller than a first threshold value. Then, for each dark pixel having the pixel value equal to or smaller than the first threshold value, the image correcting apparatus detects calculates the shading variation between the dark pixel and the corresponding surrounding pixels, calculates a correction amount based on the calculated shading variation, and performs image correction with the calculated correction amount.
Abstract: A method for repairing a guide vane segment of a gas turbine, the guide vane segment including at least two guide vanes as well as an inner and an outer shroud. At least one guide vane is irreparably damaged and is separated from the guide vane segment while the guide vane segment is completed by joining at least one replacement vane. If the one irreparable guide vane is located in one half of the segment outside the circumferential center of the guide vane segment, or if the several irreparable guide vanes are located in the same half of the segment, the matching number of guide vanes to be separated from the segment and replacement vanes to be joined to the segment are determined first. The determined number of replacement vanes are then joined to the guide vane segment. The same number of guide vanes, including the at least one irreparable guide vane, are finally separated from the guide vane segment.

Abstract: A recognition result extraction unit and an agreement determination unit are provided. The recognition result extraction unit extracts, from a recognition result storage unit, N best solutions A and B obtained by an utterance B. The utterance B follows an utterance A corresponding to the N best solutions A and made by a speaker b who is different from a speaker of the utterance A. In a case where a repeat utterance determination unit determines that the N best solutions B are N best solutions obtained by a repeat utterance B according to the utterance A corresponding to the N best solutions A, when the best solution A and B are different each other, the agreement determination unit determines that some or all of the N best solutions A can be replaced with some or all of the N best solutions B.

Abstract: The optical path of the light having spread at each point of an object to be shot is limited by an iris unit of a density filter. Since the density filter unit has a desired transmittance characteristic, the amount of the light passing through the density filter unit continuously changes from the center of the luminous flux toward the periphery. After the luminous flux forms an image on the image forming surface, it spreads toward the light-receptive surface of an image sensor, and becomes an image spreading on the light-receptive surface in a predetermined range.
