Systems and methods are provided for controlling predictive medical monitoring. A non-linear-predictive-guide model estimates a patient parameter that is used as a guide in a deep neural network for improving accuracy of estimation by the deep neural network. The guide model generates a guiding first estimated patient parameter based on the guide model and patient input data. The deep neural network generates a second estimated patient parameter based on the deep neural network, the patient input data, and the guiding first estimated patient parameter. The deep neural network includes an input layer that receives the guiding first estimated patient parameter, and hidden layers including respective artificial neurons configured to perform a linear or nonlinear transformation on output of at least one artificial neuron from an adjacent layer in the deep neural network. An output layer receives at least one output from a hidden layer.

Systems and methods are described for automatically identifying a food item. A color image and a thermal image are received by an electronic processor with a first food item in the field of view of both the color image and the thermal image. The electronic processor identifies a region of pixels in the color image that corresponds to the first food item based at least in part on a temperature intensity of the pixels in the identified region of pixels relative to other pixels in the thermal image. At least one feature is extracted from the identified region of pixels in the color image corresponding to the first food item and the electronic processor automatically identifies a type of food corresponding to the first food item based at least in part on the at least extracted feature.

An energy management system includes a number of power sources, a first set of energy storage devices (ESDs), a second set of ESDs, and a control system. The first set of ESDs is coupled between the power sources and a load and has a first set of operating characteristics. The second set of ESDs is also coupled between the power sources and the load and has a second set of operating characteristics that are different from the first set of operating characteristics. The control system is configured to selectively deliver power from one of the plurality of power sources to the first plurality of ESDs, the second plurality of ESDs, or both and selectively deliver power from the first plurality of ESDs, the second plurality of ESDs, or both to the load based on short and long term variations in a set of energy delivery system characteristics.

An example method is provided and includes a multicast data message from a data source, the message in a first virtual local area network and being associated with a multicast group. The method also includes calculating a hash value based on the virtual local area network, the data source, and the multicast group, determining a port for a designated router in a Layer-2 network based on the hash value, and switching the multicast data message to the port that was determined.

A combustion gas measurement apparatus mounted in a gas turbine including: a tunable laser generating a radiation beam passing through a combustion gas path; a controller tuning the laser to emit radiation having at least a first selected wavelength and a second selected wavelength which both correspond to temperature-dependent transitions of a combustion species of the gas, wherein the first selected wavelength and the second selected wavelength are not near absorption peaks of neighboring wavelengths; a detector sensing the radiation beam passing through the combustion gas and generating an absorption signal indicative of an absorption of the beam by the combustion gas at each of the first wavelength and the second wavelength, and a processor executing a program stored on a non-transitory storage medium determining a combustion gas temperature based on a ratio of the adoption signals for the first wavelength and the second wavelength.

Techniques to optimize root network node selection for network tree paths are provided. A network disruption event is detected. Network nodes in the network are configured with root priorities. Network nodes in a first set of the network nodes operate as root nodes for ordered network tree paths. Root priority information is retrieved from a database for each of the network nodes. Based on the root priority information, network nodes are selected for a new set of network nodes to operate as new root nodes for new ordered network tree paths upon occurrence of the network disruption event. The new set of network nodes comprises common network nodes present in the first set. An order of the network nodes in the new set is determined such that at least one common network node in the new set is maintained in the same order as that in the first set.

Systems and methods may be provided embodying an optimized Trill LAN network hello mode. The optimized hello mode may allow the number of LAN hellos exchanged to be reduced significantly in a steady state mode of operation. No modifications to the current Trill specification are needed and in a converged state (when designated RBridge election and appointed forwarder appointments are complete), only 1 hello PDU per RBridge is originated in every hello interval.

In one embodiment, a method includes obtaining an indication that a state associated with a node is to be changed and preventing data from being received on a first link. The method also includes updating at least one selected from a group including an incoming interface check (IIC) table and an outgoing interface (OIF) table to reflect the state. The state indicates that a second link is to be activated. Finally, the method includes allowing the data to be received on the second link after updating either or both the IIC table and the OIF table and after the timer duration for the NULL value for IIC has expired.

In one embodiment, a method includes receiving information on layer 2 topologies at a network device in a core network, mapping one or more Virtual Local Area Networks (VLANs) to the layer 2 topologies to provide differentiated services in said layer 2 topologies, defining multiple paths for each of the layer 2 topologies, and forwarding a packet received at the network device on one of the multiple paths. An apparatus for providing differentiated services in layer 2 topologies is also disclosed.
