Abstract: A computed tomography scanner may include a component mounting assembly, an x-ray tube, a filter assembly, and a detector assembly. The filter assembly filters an x-ray fan or cone beam generated by the x-ray tube such that the x-ray beam comprises a high dose portion and one or more low dose portions. The filter assembly reduces the photon count of the low dose portions. The x-ray tube may be coupled to the component mounting assembly at a first end and the detector assembly coupled at a second end that is opposite from the first end. The component mounting assembly is rotatable about a rotation axis. The detector assembly includes an array of individual detector elements capable of detecting x-ray photons of the x-ray beam. The high dose portion strikes a high resolution region of the detector assembly and the low dose portion strikes a low resolution region of the detector assembly.

Abstract: In one embodiment, a method for generating an ensemble classifier may include transforming multidimensional training data into a plurality of response planes. Each of the response planes includes a set of confidence scores. The response planes are transformed into a plurality of binary response planes. Each of the binary response planes include a set of binary scores corresponding to one of the confidence scores.

A predicted performance of a child combination of the recognition algorithms corresponding to the combinations is generated. The predicted performance is based at least in part upon the metrics. Parent recognition algorithms are selected from the recognition algorithms based at least in part upon the predicted performance. The ensemble classifier is generated and includes the parent recognition algorithms.

Abstract: The embodiments described herein generally relate to a discrete event simulation (DES) tool which combines the process-driven model and the event-driven model. This integrated process (which uses entities) and event simulation framework according to the various embodiments provides a platform that is appropriate for all combinations of simulation model requirements and at the same time provides higher level of model abstraction. The DES tool instantiates a new paradigm that permits flow of entities at the event-driven model layer that is analogous to their treatment at the process-driven model layer.

Abstract: Embodiments of this invention comprise modeling a subject's state and the influence of training scenarios, or actions, on that state to create a training policy. Both state and effects of actions are modeled as probabilistic using Partially Observable Markov Decision Process (POMDP) techniques. The POMDP is well suited to decision-theoretic planning under uncertainty. Utilizing this model and the resulting training policy with real world subjects creates a surprisingly effective decision aid for instructors to improve learning relative to a traditional scenario selection strategy. POMDP provides a more valid representation of trainee state and training effects, thus it is capable of producing more valid recommendations concerning how to structure training to subjects.
