Patent number: 10970115Abstract: For a task that has been partially executed, a residual complexity index is computed, the task being of a complexity that cannot be ascertained prior to executing the task. An evaluation is made whether the residual complexity index exceeds a cost of a resource that should be considered for allocation to the task. When the evaluation is affirmative, a priority of the task is established relative to a second task. The resource is scheduled to perform the task according to a timing, the timing being determined using the cost of the resource. The resource is allocated to the task according to the timing.Type: GrantFiled: November 7, 2018Date of Patent: April 6, 2021Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Munish Goyal, Qin S.

Patent number: 10748171Abstract: Aspects automatically minimize marketing rates as a function of optimized response rate models. Response rates are estimated from marketing offers targeted from a first entity to topic-entity pairs at respective specified marketing rates as a function of relative differences in their consumer sentiment scores. Marketing offers are targeted to a subset of the topic-entity pairs that each have estimated response rates meeting a threshold response rate constraint. Respective costs and actual rates of response from consumers are determined for the targeted offers. Response rates are modeled to determine modeled response parameters for the topics and entities of the subset topic-entity pairs as regressions of minimized differences in value between estimated and actual response rates. Marketing rates of the subset entity-topic pairs are minimized to meet the threshold response rate constraint and a marketing cost constraint as a function of the modeled response parameters.Type: GrantFiled: September 14, 2016Date of Patent: August 18, 2020Assignee: International Business Machines CorporationInventors: Gabriel Asaftei, Munish Goyal, Qin S. Held, Steven M. O'Brien, Jr.

Patent number: 10563616Abstract: A method of operating a gas turbine engine includes generating a flow of combustion products from a gas turbine generator that has a gas generator axis of rotation. A duct is oriented in a first position to direct the flow of combustion products that have passed over at least one gas generator turbine rotor through a fan drive turbine in response to a first desired flight condition. An axis of rotation of the fan drive turbine is transverse to a gas generator axis of rotation. The duct is oriented in a second position to direct the flow of combustion products that have passed over at least one gas generator turbine rotor through an augmentor section in response to a second desired flight condition.Type: GrantFiled: October 23, 2018Date of Patent: February 18, 2020Assignee: UNITED TECHNOLOGIES CORPORATIONInventor: Steven M.
