Abstract: A turbine engine has a combustor in a core air flow path that generates combustion gases and a fuel and steam system fluidly coupled to the combustor. The fuel and steam system has a steam system to provide a steam flow to the combustor and a fuel system to provide a primary fuel flow and a secondary fuel flow to the combustor. The fuel system has a first state in which there is a first flow rate of the secondary fuel flow to the combustor and a second state in which there is a second flow rate of the secondary fuel flow to the combustor. The first flow rate and the second flow rate are different. The first state and the second state are based on a condition of the steam system.

Abstract: An initial probability of occurrence of a stochastic defect over an inspection area of a workpiece is received. All locations of the stochastic defects are sorted by the initial probability of occurrence. A cumulative expected defect count is determined and the cumulative expected defect count is normalized to be a fraction of a total expected defect count. A number of defect locations is determined to capture potential stochastic defects above a threshold of total stochastic defects.

Abstract: Based on an initial probability of occurrence of a stochastic defect over a layout of a workpiece, a subset of locations on the workpiece are selected where the initial probability is above a threshold. The subset of locations are grouped by pattern shapes. An expected defect count is determined for each of the pattern shapes. A subset of the pattern shapes is then selected for repair.

Abstract: Described herein are devices, systems, methods, and processes for determining the geo-positions of access points (APs) in a wireless network. The techniques involve utilizing geo-positioning data including global navigation satellite system (GNSS) measurements, wireless local area network (WLAN) signal measurements, air pressure measurements, preexisting knowledge, or any combination thereof. The GNSS measurements may include pseudo range measurements. The WLAN signal measurements can include time of arrival (ToA), channel state information (CSI), and/or received signal strength indicator (RSSI) measurements. The geo-position of each AP is calculated by applying Bayes' theorem to all available geo-positioning data and selecting the geo-position hypothesis with the highest probability. The geo-positions of the APs can be updated when a new measurement is obtained. The techniques can handle diverse AP deployments including heterogeneous APs with varying sensor capabilities.

Abstract: Using an initial probability of occurrence of a stochastic defect over an inspection area of a workpiece, one or more defects within the inspection area are imaged using an optical tool or an electron beam tool. A probability of occurrence of a stochastic defect at each of the defect locations is generated using the model. The defect locations are grouped into probability bins. A consistency between the initial probability and observed results is determined and the model can be tuned based on the consistency.

Abstract: A user equipment device may include a radio that conveys wireless data with one or more base stations using a set of component carriers (CCs) that are concurrently-active under a carrier aggregation scheme or a dual connectivity scheme. When in a thermally-constrained state, a resource manager on the radio may intelligently select a CC to drop from use in conveying the wireless data. The resource manager may select the CC to drop based on the bandwidths, data rates, error rates, and/or activation/deactivation rates of the set of CCs, a power budget assigned to the radio, and/or information about the demodulation and decoding clusters in a modem of the radio. Selecting the CC to drop in this way may provide greater power and temperature reduction at the radio and/or less wireless performance reduction than blindly dropping the most recently added CC from use in conveying the wireless data.
