Method and system for improving a part's resistance to stress induced failure

A method and system for designing a part with improved fatigue life and resistance to stress corrosion cracking in which residual stresses existing in the part are accounted for. The performance criteria and operating conditions of the part are assessed and a total stress state is determined from the sum of the residual stresses and applied stresses acting on the part. Unified Fatigue Performance Model or Smith-Topper-Neuber parameters are used to determine fatigue life functions which, in turn, are used in conjunction with a fatigue design diagram to determine the appropriate residual stress to introduce in order to optimize the part's resistance to stress induced failure mechanisms. A residual stress distribution is then designed to avoid distortion of the part while still imparting the beneficial effects of compressive residual stress.

Lateral collection architecture for sls detectors

Lateral collection architecture for a photodetector is achieved by depositing electrically conducting SLS layers onto a planar substrate and diffusing dopants of a carrier type opposite that of the layers through the layers at selected regions to disorder the superlattice and create diode junctions oriented transversely to the naturally enhanced lateral mobility of photogenerated charge carriers within the superlattice. The diode junctions are terminated at a top surface of the photodetector within an SLS layer of wide bandgap material to minimize unwanted currents. A related architecture disorders the superlattice of topmost SLS layers by diffusing therethrough a dopant configured as a grid and penetrating to a lower SLS layer having the same carrier type as the dopant and opposite that of the topmost layers to isolate pixels within the topmost layers. Ohmic contacts may be deposited on doped regions, pixels, and substrate to provide desired external connections.

Mid-Cycle Fuel Injection Strategies

A method and apparatus are disclosed for introducing a gaseous fuel into a combustion chamber of an internal combustion engine. The method includes dividing the engine map into three distinct operating regions, with different operating modes in each region. When the engine is operating in a low load region, gaseous fuel is introduced to the combustion chamber during an intake stroke before an intake valve associated with the combustion chamber closes. When the engine is operating in a high load low-speed region, gaseous fuel is directly injected into the combustion chamber during a compression stroke after the intake valve is closed. When the engine is operating in a high load high-speed region, a split injection strategy is employed with a first portion of the gaseous fuel introduced into the charge before the intake valve closes and a second portion being injected after the intake valve is closed.

Method and system for reheating flue gas using waste heat to maintain dry chimney stack operation

ActiveUS20160169510A1Improve energy efficiencyEliminate condensation and corrosionEmission preventionChemical industryWorking fluidWater vapor
Flue gas is a by-product of many energy and industrial plants and is typically emitted through a chimney stack. If the flue gas temperature in the chimney stack drops below the flue gas dew point, condensation of water vapor and acid gases ensues. These gases are very corrosive for chimney stacks designed to operate in a dry condition. The Flue Gas Reheat System of the present invention continuously and proactively manages flue gas chimney stack temperatures above the dew point in order to optimize emission control and effectuate energy efficiency improvements in industrial plants. Waste heat is harvested from the exterior surfaces of existing steam and pollution control equipment through conduction, convection and radiation. This heat is transferred to a working fluid. The working fluid is then directly mixed with the flue gas prior to the flue gas entering the chimney stack to raise the temperature of (or re-heat) the flue gas above its dew point to maintain a dry chimney stack condition. The use of residual or waste heat from throughout the plant and the minimal equipment required to harvest the waste heat reduces the operating cost and improves the overall reliability of the system. This method is useful in many industries, including electric power generation plants and other energy intensive process industries that seek emission control and various boiler and fuel energy efficiency improvements, many of which improvements result in a reduction in normal chimney stack temperature.

Reflection filter

A method and apparatus for generating a reflection filter. The method comprises the steps of determining an averaged step response of an acquired signal and generating a spectrum response from the averaged step response. A time at which a reflection in the averaged step response begins is determined and information in the averaged step response after the determined time when the reflection begins is replaced with an ideal flat line response to generate a required step response. A spectrum response is generated from the required step response and each frequency point of the spectrum response corresponding to the required step response is divided by each frequency point of the spectrum response corresponding to the averaged step response to generate a spectrum of the reflection filter. The result of the dividing step is processed to generate a reflection filter impulse response.
