The current problem of handling thousands of workflows and hundreds of tasks associated with these workflows within the current ALP architecture is enormous. In this effort we propose efficient and scalable data structure and algorithms that can order the workflows and associated tasks to be processed by the Assessor. In addition, we provide the capability to correlate workflows with actual logi ...

We shall develop a dynamic agent web architecture and software prototype that builds on top of COTS database integration technology to deliver view management and data mining services.The data mining services shall consist of case based reasoning and association. We shall use case based reasoning and association agents in identifying new links and relationships within data contain in shipboar ...

Sucessful completion of Phase I efforts shall provide the Air Force with an intelligent dynamic data mining architecture and demonstration prototype. We shall develop the concept of a profile that shall be used as a basis for identification and linking of relationships based on a rough sketch or profile of the situation. The use of profiles shall be used in enhancing existing case-based and asso ...

Master artwork for Air Force systems is traditionally delivered on polyester-based mylar film. This film tends to degrade over time, even when stored in climate-controlled facilities. In addition, drawings must be digitized before circuit boards can be manufactured, which is an expensive and time consuming step. A reliable and repeatable artwork conversion process is needed.This project will pe ...

ACX proposes an alternate approach to damping for extreme environments, which uses an electrically shunted, surface mounted, smart material. This shunting approach has been most widely used in less extreme environments in conjunction with piezoceramic materials. The smart material is bonded to the surface of the target structure, in this case a part inside an aircraft engine. Stress on the part ...

Active Control eXperts, (ACX) Inc. proposes to design, fabricate, and demonstrate a novel hybrid vibration ccntrol actuator system capable of very precise, controllable motion. This system will combine the advantages of a capacitive actuator with feedback control capability. This system will possess the force and stroke characteristics of a small hydraulic device and the bandwidth of electric moto ...

In many structures with vibration problems, the nature of the problem is uncertain, or varies over time. Thus it is not possible 'a priori to design a linear, time-invariant, (LTI) feedback control law which is guaranteed to meet performance, or possibly even stability requirements over the entire operating range. These applications require an intelligent control system which can adapt to the ch ...

ANR technologies have been successfully incorporated in communication headsets to improve speech intelligibility and hearing conservation in high noise environments. This Phase I research effort will introduce advancements in optimal controller/headset architectures that will lead to: greater SPL attenuations at the ear, significantly extended ANR bandwidth, and improvements in speech intelligibi ...
