A method for identifying corrosion under insulation (CUI) in a structure comprises receiving thermographs from the structure using an infrared camera, applying filters to the thermograph using a first machine learning system, initially determining a CUI classification based on output from the filters, and validating the initial CUI classification by an inspection of the structure. The first machine learning system is trained using results of the validation. Outputs of the first machine learning system and additional structural and environmental data are fed into a second machine learning system that incorporates information from earlier states into current states. The second machine learning system is trained to identify CUI according to changes in the outputs of the first machine learning system and the additional data over time until a second threshold for CUI classification accuracy is reached. CUI is thereafter identified using the first and second machine learning systems in coordination.

Grain dryer of the type comprising a vertical main structure consisting of a central body through which the grain to be dried passes, a front hot air intake chamber and a rear used air outlet chamber, being that the main body has in its upper part an entrance from where wet grains are loaded, underneath which there is a loading hopper that communicates with the central body, wherein the grain descends along the central body within which it is dried during its fall by a flow of hot air that passes through the mass of grain, finally exiting through a discharge hopper arranged at the lower end of the dryer, the dryer of the invention being characterized in that it allows to significantly reduce the energy consumption in order to obtain a better quality of grain and a process much faster than conventional ones due to the arrangement of one or more preheating chambers without extraction of moisture from the grain.

Various examples are provided related to high-resolution sediment sensing including, e.g., water depth and/or water velocity sensing. In one example, a sediment dynamics monitoring system for scour, erosion or deposition detection includes a fiber-optic distributed temperature sensing (FO-DTS) sediment dynamics monitoring device including a support structure; a FO cable providing continuous sensing along a length of the support structure; and a heating element collocated along the FO cable; a power controller configured to control heating of the heating element; and a DTS system that can measure a temperature profile along a length of the FO cable. An anomaly in the measured temperature profile indicates an interface surrounding the FO-DTS sediment dynamics monitoring device. interface can be a sediment-water interface or a water-air interface.

The present disclosure relates to a computer based system for collecting, analyzing and presenting temperature information from sensors associated with an HVAC system. The system makes use of a processor for communicating with the plurality of sensors and obtaining temperature data reported by each of the sensors. A graphical user interface (GUI) module is provided which is embodied in a non-transient medium and configured to run on a computing device having a display screen. The user GUI module uses the temperature data, in real time, to generate a graph on the display screen. The graph includes a plurality of components each having different indicia to indicate groups of sensors that are below a predetermined lower temperature limit, above a predetermined upper temperature limit, and within a predetermined temperature range. Standard deviation information may be supplied with the graph which relates to the maximum standard deviation of those groups of sensors that are reporting temperatures above and below the predetermined temperature range.

A temperature gauge display and a method of using the same to determine whether a saturated steam temperature is as it should be or if the saturated steam temperature is in the unacceptable subcooled range. The gauge display embodies a dial face providing a pointer movable along the dial face in the clockwise directions for indicating steam system temperature while an arcuate colored portion is located along a portion of the path of the pointer so that the pointer, the dial face, and the colored portion visually cooperate to indicate sufficient operation of the system being monitored, wherein the colored portion defines a subcooled range of saturated steam temperature for a specific saturated steam pressure.

A handheld apparatus for measuring atmospheric temperature inversions consisting of a battery powered electronic display portion, a folding pole portion, and a temperature sensor protected from sources of heat radiation. An electronic circuit measures air temperatures at multiple heights accurately by automatically determining when readings have stabilized and reads a tilt sensor to assure temperature readings are at the proper height. Affixing said temperature sensor to the end of a pole while the opposite end is held in the user's hand facilitates waving of the temperature sensor end through the air to increase air flow, therefore, assuring quicker response and accurate air temperature readings. An electronic display indicates the presence and intensity of an atmospheric temperature inversion.
