Abstract: The present disclosure provides novel techniques to segment mobile entities based on signals from mobile devices associated with these mobile entities. In certain embodiments, a data file is built for each mobile entity to transform originally extremely high dimensional raw data derived from mobile devices communicating with a network into structured data characterizing associated mobile entities. The data files are structured for filtering and searching with respect to features associated with the signals from mobile devices, including location and non-location features. The data files are used to determine feature gains corresponding respectively to features related to a mobile segment. The features include first features of a first type and second features of a second type. The feature gains are used, among other things, to rank mobile entities for the mobile segment, with feature gains corresponding to the first features given a larger weight than feature gains corresponding to the second features.

Abstract: An automated control loop for dynamically adjusting a temperature of wet steam is provided. This leads to increased heat transfer and decreased fouling in a reboiler of a distillation column used for distilling a petrochemical. The control loop includes controlling the combining of condensed water with dry steam to produce the wet steam. The produced wet steam is input to the reboiler in order to transfer heat to the petrochemical while being converted to the condensed water. The control loop further includes monitoring a pressure of the produced wet steam, and setting a target temperature for the produced wet steam based on the monitored pressure. In addition, the control loop includes monitoring the temperature of the produced wet steam, and adjusting a proportion of the condensed water in the produced wet steam in response to the monitored temperature deviating from the set target temperature by at least a threshold value.
