Abstract: Various aspects of the present disclosure are directed towards devices, systems, and methods for optimizing debt portfolio by actively monitoring for rate quotes from one or more lenders and performing real-time optimization to determine global optimum parameters in order for the user to be qualified for the optimal loan product that meets the user's goals.

Abstract: A multi-pass catalytic converter can divide a catalyst block into several catalytic volumes and enable the exhaust gas to flow through each volume in two or more passes consecutively. As the exhaust gas in an early pass can emit sensible thermal energy and chemical reaction energy to preheat the remaining catalytic volumes via conductive heat transfer, it can shorten the catalyst light-off time for the later passes and the whole catalyst block. By recouping the previously lost dissipating heat from the early catalytic volume, the present disclosure can significantly reduce the catalyst light-off time and emission concentration. Furthermore, one or more mixing chambers can be utilized to thoroughly mix the exhaust gas.

Abstract: A gas turbine engine component (10), having: a base layer (60) including an array (110) of pockets (52) separated by raised ribs (36), and a film cooling hole (70) through the base layer in each pocket; and a cover sheet (62) diffusion bonded to the raised ribs and including an impingement hole (72) for each pocket of the array of pockets. The raised ribs include a thickness (104) that is less than half of a smallest dimension (96) of the pocket. The component is configured to receive combustion gases from a combustor and accelerate and deliver the combustion gases onto a first row of turbine blades without a turning vane.

Abstract: A programmable processor receives engine speed data for an engine. The programmable processor calculates a work corresponding to a component of the engine. The calculated work is based on a change in the engine speed data over a range. A predicted work value is read from a table based on an engine speed and first metric. A value is transmitted to a control system when the calculated work is not the predicted work value. The value, when implemented by the control system, reduces a difference between the predicted work value and the calculated work for the component.

Abstract: Implementations of the current subject-matter include systems, methods, and techniques that assist with controlling of injected fuel and spark timing across a range of operating conditions. For example, a prediction technique can be used to predict variation in combustion cylinder wall and internal metal temperatures over time, thereby enabling the likely effect of one of the calculated temperatures on airflow and hence on combustion to be assessed. The obtained information can be used to adjust fuel flow or spark timing in accordance with the predicted temperature variation from steady state conditions.
