    Abstract: Various embodiments relate to a system and method of suppressing contrails emitted from an aircraft. One such system comprises a semi-closed cycle gas turbine engine of an aircraft that exhausts gases in use; a recuperator component that is positioned within an exhaust gas stream of the semi-closed cycle gas turbine engine to remove a portion of the exhaust gas stream in a form of heat energy; and one or more additional heat exchangers in a recirculation path that are configured to condense the heat energy of the portion of the exhaust gas to remove water vapor from the exhaust gas stream. Other systems and methods are also provided.

    Abstract: The present disclosure provides systems and methods for predicting the occurrence of an outbreak of an infectious disease. One such method includes acquiring environmental risk factor data associated with a particular disease, wherein the environmental risk factor data corresponds to a particular geographic region; acquiring social risk factor data associated with the particular disease; applying a prediction algorithm to the environmental and social risk factor data to generate a disease risk model for generating at least a trigger prediction and a transmission prediction for a disease-causing pathogen at the particular geographic region; generating the trigger prediction by applying the disease risk model to a forecast of data for a first lead time for the particular geographic region; and/or generating the transmission prediction by applying the disease risk model to the transmission prediction for a second lead time for the particular geographic region. Other methods and systems are also provided.

    Abstract: The present disclosure describes system and methods for determination of building code performance. One such method comprises performing design model validation, wherein design model validation comprises entering building permit application file information and checking the building permit application file information against relevant codes and regulations, using a taxonomy or neural natural language processing techniques or artificial Intelligence; performing exchange model code checking, wherein exchange model code checking comprises using a plurality of exchange models; performing code conformance checking, wherein the code conformance checking comprises receiving a request from the exchange models and passing the building permit application file information to code checking modules configured to check building code provisions and one or more regulations per local, state, national or international requirements; performing verification reporting based on input provided from the code checking modules; and performing results reporting based on findings of the verification reporting.
