Abstract: A method, system and computer program for modelling an optimal mine plan is disclosed. The life of mine is divided into a plurality of increasing lengths of time (FIGS. 2 and 3) and performing optimisation steps, with each step being performed once for a predetermined time period for the remaining life of mine. Material may be stockpiled or may be sent direct to product or to waste without any stockpiling. A decision (block 10 in FIG. 1) is made as to which material is sent to product in each time period for the remaining life of mine. In each predetermined time period, material with a grade greater than a marginal grade that is not sent to produce is sent to stockpile and all material less than a marginal grade is sent to waste (14).

Abstract: A method for operating an internal combustion engine Exhaust Gas Recirculation (EGR) system that includes producing an EGR valve position signal to decrease the amount of exhaust gas passed to the EGR cooler when a processor determines the EGR cooler efficiency is less than the predetermined level and producing an EGR coolant valve position signal to decrease the amount of coolant passed to the EGR cooler when such processor determines the EGR cooler efficiency is less than the predetermined level. The processor produced EGR valve and the EGR coolant valve position signals result in regeneration within the cooler, returning the effectiveness of the cooler to a near “clean” condition.

Abstract: Systems and methods for updating the PF soot load of an engine are provided herein. In one embodiment, the method may include performing regeneration in response to both pressure-based measurements as well as estimated soot loading independent of the pressure-based measurements, where during conditions in which the pressure-based measurements may be inaccurate, the soot load is estimated based on operating conditions and previous pressure-based measurements that occurred during previous conditions in which the pressure-based measurements are more accurate. In this way, more continuous monitoring of particulate filter loading is provided, while taking advantage of pressure-based measurements from the most recent accurate reading, for example, and operating conditions that have transpired since such reading, including transient conditions. Thus, more appropriately timed regeneration may be provided.

Abstract: An image recording apparatus (2000) is disclosed, which includes forming elements (2002) for forming an image, a memory (2006) indicating relative desirability of utilizing the forming elements (2002) for forming the image, and processing unit (2008) for computing image recording signals using input image signals (2012) and the stored data. The use of a particular forming element is thereby biased dependent upon the relative desirability data for the other forming elements and the corresponding input image signals for the other forming elements.

Abstract: A method for forming carbon nanotube field effect transistors, arrays of carbon nanotube field effect transistors, and device structures and arrays of device structures formed by the methods. The methods include forming a stacked structure including a gate electrode layer and catalyst pads each coupled electrically with a source/drain contact. The gate electrode layer is divided into multiple gate electrodes and at least one semiconducting carbon nanotube is synthesized by a chemical vapor deposition process on each of the catalyst pads. The completed device structure includes a gate electrode with a sidewall covered by a gate dielectric and at least one semiconducting carbon nanotube adjacent to the sidewall of the gate electrode. Source/drain contacts are electrically coupled with opposite ends of the semiconducting carbon nanotube to complete the device structure. Multiple device structures may be configured either as a memory circuit or as a logic circuit.

Abstract: A conductive layer in an integrated circuit is formed as a sandwich having multiple sublayers, including at least one sublayer of oriented carbon nanotubes. The conductive layer sandwich preferably contains two sublayers of carbon nanotubes, in which the carbon nanotube orientation in one sublayer is substantially perpendicular to that of the other layer. The conductive layer sandwich preferably contains one or more additional sublayers of a conductive material, such as a metal. In one embodiment, oriented carbon nanotubes are created by forming a series of parallel surface ridges, covering the top and one side of the ridges with a catalyst inhibitor, and growing carbon nanotubes horizontally from the uncovered vertical sides of the ridges. In another embodiment, oriented carbon nanotubes are grown on the surface of a conductive material in the presence of a directional flow of reactant gases and a catalyst.

Abstract: Design structure embodied in a machine readable medium for designing, manufacturing, or testing a design in which the design structure includes shallow trench isolation filled with liquid phase deposited silicon dioxide (LPD-SiO2). The shallow trench isolation region is used to isolate two active regions formed on a silicon-on-insulator (SOI) substrate. By selectively depositing the oxide so that the active areas are not covered with the oxide, the polishing needed to planarize the wafer is significantly reduced as compared to a chemical-vapor deposited oxide layer that covers the entire wafer surface. Additionally, the LPD-SiO2 does not include the growth seams that CVD silicon dioxide does. Accordingly, the etch rate of the LPD-SiO2 is uniform across its entire expanse thereby preventing cavities and other etching irregularities present in prior art shallow trench isolation regions in which the etch rate of growth seams exceeds that of the other oxide areas.

Abstract: To isolate two active regions formed on a silicon-on-insulator (SOI) substrate, a shallow trench isolation region is filled with liquid phase deposited silicon dioxide (LPD-SiO2) while avoiding covering the active areas with the oxide. By selectively depositing the oxide in this manner, the polishing needed to planarize the wafer is significantly reduced as compared to a chemical-vapor deposited oxide layer that covers the entire wafer surface. Additionally, the LPD-SiO2 does not include the growth seams that CVD silicon dioxide does. Accordingly, the etch rate of the LPD-SiO2 is uniform across its entire expanse thereby preventing cavities and other etching irregularities present in prior art shallow trench isolation regions in which the etch rate of growth seams exceeds that of the other oxide areas.

Abstract: A field effect transistor is formed having wrap-around, vertically-aligned, dual gate electrodes. Starting with a silicon-on-insulator (SOI) structure having a buried silicon island, a vertical reference edge is defined, by creating a cavity within the SOI structure, and used during two etch-back steps that can be reliably performed. The first etch-back removes a portion of an oxide layer for a first distance over which a gate conductor material is then applied. The second etch-back removes a portion of the gate conductor material for a second distance. The difference between the first and second distances defines the gate length of the eventual device. After stripping away the oxide layers, a vertical gate electrode is revealed that surrounds the buried silicon island on all four side surfaces.

Abstract: A dielectric in an integrated circuit is formed by creating oriented cylindrical voids in a conventional dielectric material. Preferably, voids are formed by first forming multiple relatively long, thin carbon nanotubes perpendicular to a surface of an integrated circuit wafer, depositing a conventional dielectric on the surface surrounding the carbon nanotubes, and then removing the carbon nanotubes to produce the voids. A layer of dielectric and voids thus formed can be patterned or otherwise processed using any of various conventional processes. Recesses formed in the dielectric for conductors are lined with a non-conformal dielectric film to seal the voids. The use of a conventional dielectric material having numerous air voids substantially reduces the dielectric constant, leaving a dielectric structure which is both structurally strong and can be constructed compatibly with conventional processes and materials.

Abstract: A seat identification system for passengers in a cabin of a commercial airliner. Four sign components, identified as the aisle, mile, row and seat components, are arranged and positioned throughout the airplane in a configuration that allows the passengers to receive information about their seats when needed. The aisle signage markers direct the passengers down the appropriate aisle which leads to their seat. The interval row markers or mile markers provide a general location of the particular row in the aircraft for the passenger's seats. The individual row markers are preferably located in the passenger service unit modules and in viewing channels in order to allow the markers to be visible from the aisle. The seat markers are located preferably on the headrest on each seat and are the final vindication that the passenger is in the correct seat.
