Abstract: The nitric oxide (NO) and nitrogen dioxide (NO2) content of lean-burn engine exhaust is beneficially prepared for selective catalytic reduction (SCR) of these oxides to nitrogen by two sidestream additions to the exhaust. An ozone-containing air stream is added to the exhaust to affect oxidation of NO to NO2. And a hydrocarbon(s) fuel constituent is added to a second humidified ozone-containing air stream and that mixture subjected to UV radiation. Strongly oxidizing hydroxyl radicals are formed by interaction of ozone, water, and UV radiation for reaction with the hydrocarbon. The resulting partially oxidized hydrocarbons (Pox) are added to the exhaust, providing effective reduction materials for the SCR of NO2 to nitrogen and water.

Abstract: A periodic structure is illuminated by polychromatic electromagnetic radiation. Radiation from the structure is collected and divided into two rays having different polarization states. The two rays are detected from which one or more parameters of the periodic structure may be derived. In another embodiment, when the periodic structure is illuminated by a polychromatic electromagnetic radiation, the collected radiation from the structure is passed through a polarization element having a polarization plane. The element and the polychromatic beam are controlled so that the polarization plane of the element are at two or more different orientations with respect to the plane of incidence of the polychromatic beam. Radiation that has passed through the element is detected when the plane of polarization is at the two or more positions so that one or more parameters of the periodic structure may be derived from the detected signals.

Abstract: Systems and methods are disclosed for using ellipsometer configurations to measure the partial Mueller matrix and the complete Jones matrix of a system that may be isotropic or anisotropic. In one embodiment two or more signals, which do not necessarily satisfy any symmetry assumptions individually, are combined into a composite signal which satisfies a symmetry assumption. The individual signals are collected at two or more analyzer angles. Symmetry properties of the composite signals allow easy extraction of overlay information for any relative orientation of the incident light beam with respect to a ID grating target, as well as for targets comprising general 2D gratings. Signals of a certain symmetry property also allow measurement of profile asymmetry in a very efficient manner. In another embodiment a measurement methodology is defined to measure only signals which satisfy a symmetry assumption. An optional embodiment comprises a single polarization element serving as polarizer and analyzer.

Abstract: One embodiment of the present invention provides a system that monitors system-calls to identify runaway processes within a computer system. First, the system monitors system-calls on the computer system during runtime, to generate a trace of system-calls made. Then, the system analyzes the trace to detect runaway processes.

Abstract: Ozone and, if necessary, water is added to an exhaust gas, such as air, containing hydrogen- and carbon-containing molecules of a pollutant. The exhaust gas is then continually flowed into one or more oxidizing reaction chamber modules. In the reaction chamber(s) the ozone- and water-containing gas is subjected to intense ultraviolet radiation (wavelength of 254 nm) to promote the formation of hydroxyl radicals to oxidize the pollutant molecules to carbon dioxide and water. The continually discharged gas is analyzed for residual ozone and hydrocarbon content and the analytical data used in feedback control of ozone addition and UV radiation intensity.

Abstract: A novel ?-galactosidase gene family and DNA sequences derived from the cloning of cDNAs encoding products of these genes are provided, as exemplified by a ?-galactosidase II protein which is encoded by a cDNA clone, pZBG2-1-4. A method for modifying cell wall metabolism which involves modifying the activity of at least one ?-galactosidase, and thus modifying the quality of the fruit is also provided. Also provided by the present invention is a DNA construct including some or all of a ?-galactosidase DNA sequence under control of a transcriptional initiation region operative in plants, so that the construct can generate RNA and, optionally, ?-galactosidase polypeptide in plant cells.

Abstract: A monitor interface cable for transmitting display data and command data between a computer system and a display monitor preferably including a microcontroller. The monitor interface cable enables both display and command data to be transmitted simultaneously from the computer system to the display monitor. Inside the computer system, data containing the commands written to a particular memory location in a video buffer card is applied to various signal lines located in the monitor interface cable. These signal lines are coupled to the microcontroller located in the display monitor which receives the commands and performs various controlling functions in response. Status information in the form of a command is transmitted back across a second signal line to the computer system where various software programs including drivers receive and process the status information. Display data is simultaneously transmitted over other signal lines also located in the monitor interface cable.

Abstract: A computer housing which includes a chassis that has a first compartment and a second compartment. The first compartment includes a first electronic assembly and a first fan that creates a flow of air through the compartment to create a compartment pressure that is less than an ambient pressure. The second compartment contains a second electronic assembly and a second fan which produces a flow of air that creates pressure within the compartment that is greater than the ambient pressure. The housing also contains an inner wall which separates the first compartment from the second compartment to inhibit air flow between the compartments.
