Abstract: A Brayton cycle engine and method for operation. The engine includes an inner wall assembly and an upstream wall assembly each extended from a longitudinal wall into a gas flowpath. An actuator adjusts a depth of the detonation combustion region into the gas flowpath between the inner wall assembly and the upstream wall assembly. The engine flows an oxidizer through the gas flowpath and the inner wall captures a portion of the oxidizer. The engine further adjusts the captured flow of oxidizer via the upstream wall and flows a first flow of fuel to the captured flow of oxidizer to produce rotating detonation gases. The engine flows the detonation gases downstream and to mix with the flow of oxidizer, and flows and burns a second flow of fuel to the detonation gases/oxidizer mixture to produce thrust.

Abstract: A safety stock correction represents a number of units over standard inventory that will meet intense increases in demand. In the safety stock correction, an average present demand, a total present demand, a total past demand for each past day, and a standard deviation of total demand are obtained. Further, an average present lead time, an average past lead time for each past day, and a standard deviation of average lead time are obtained. A standard deviation of lead time demand is obtained, which is the square root of a sum of a product of the average present lead time and the square of the standard deviation of total demand and a product of the average present demand and the square of the standard deviation of average lead time. The safety stock correction is a product of a service level and the standard deviation of lead time demand.

Abstract: Systems and methods are provided for creating and maintaining an ecosystem, such as for trading securities. For example, in one system, at least one eligibility prerequisite is identified—governing whether an entity is eligible to participate in the ecosystem—and whether the entity meets the eligibility prerequisite(s) is determined. In addition, at least one ecosystem rule is identified, governing whether an entity is qualified to participate in the ecosystem. An eligible entity may execute a contract in which the entity agrees to adhere to the ecosystem rule(s), thus allowing the entity to participate in the ecosystem. The entity may then enter into at least one designated ecosystem transaction, such as buying a security. Participants in the ecosystem may include issuers of securities, investors, brokers, dealers, and research analysts. In this example, the ecosystem seeks to maximize liquidity and transparency while minimizing regulatory obligations.

Abstract: A technique, system, and computer program for improving access to shared resources in a computing system. The shared resources are grouped into application-defined resource sets. Mutual exclusion semaphores are used. A semaphore is associated with each resource set to provide mutually-exclusive (serialized) access to the resources in the set. The number of semaphores will be smaller (typically, much smaller) than the number of resource sets, so that a given semaphore will be associated with multiple of such sets. Thus, the set of semaphores is striped across the collection of resource sets. This greatly increases allowable parallelism in accessing shared resources, while reducing the number of semaphores that are required.
