Abstract: Hydrocarbon conversion and transportation methods and apparatuses are provided. An apparatus may apply electron beam irradiation to hydrocarbons (i.e., natural gas) to convert the hydrocarbons to liquid fuel. Lower-weight hydrocarbons may be converted into medium-weight organics through a gas to liquid process (GTL). The electrons may generate radicals that facilitate desired reactions. The hydrocarbons may be temperature and pressure controlled. For example, the hydrocarbons may be at lower temperatures (e.g., cryogenic or otherwise below ambient) and/or at higher pressures (e.g., greater than standard atmospheric pressures). Temperature suppression may reduce decomposition reactions. A high energy electron beam (e.g., 500 keV or higher, such as 10 MeV) could be used for the conversion process. The hydrocarbon may be liquefied. The liquid-like, higher density lower-weight hydrocarbons may lead to radical-neutral interactions.

Abstract: Systems, methods, and apparatuses are disclosed that determine a spark timing correction for an internal combustion engine during a transient event. The spark timing correction delays the spark timing to reduce or mitigate knock. The spark timing correction is based on a lambda difference between a steady state lambda that is based on engine speed and engine torque and a feedback lambda from operation of the engine. The feedback lambda can be based on a calculated lambda or a sensed lambda.

This improves the accuracy and efficiency of the obtained decision-making thresholds, thereby enhancing the accuracy of multi-model facial recognition.
