Abstract: Provided is a plug of a grid-side power cable assembly connected to a cable installment type charging control device for charging an electric vehicle (EV) by using power of a grid-side. An exclusive socket detecting part detects whether a socket connected to the plug is an exclusive socket for the plug. A normal operation signal generating part generates a signal notifying whether the exclusive socket is detected. A voltage dividing part outputs a voltage so that an output voltage in a case in which the grid-side assembly is short-circuited is different from that of the grid-side power cable assembly in a case in which the signal is generated.

Abstract: A method of predicting food items consumed by a user of a food-logging application is disclosed. Loggings of consumptions of food items are received. A predictive model is generated based on the received loggings. The predictive model generates a prediction of one or more additional food items that a target user will consume or is likely to have consumed (e.g., at a particular time). The prediction is generated based on an application of the predictive model to one or more data items (e.g., data items streaming into the system in real time from the target user or other users that are relevant to food consumptions by the target user). The prediction of the consumption of the one or more additional food items by the user may then be communicated for presentation to the target user in a user interface.

Abstract: Disclosed is a method of preparing a drilling fluid and lube base oil using biomass-derived fatty acid, including hydrogenating a fatty acid mixture derived from fat of biological origin so as to be converted into a fatty alcohol mixture, which is then dehydrated to give a C16 and C18 linear internal olefin mixture, which is then oligomerized to give olefinic lube base oil, followed by hydrofinishing to remove the olefin, yielding high-quality lube base oil (e.g. Group III or higher lube base oil). The C16 and C18 linear internal olefin mixture, which is a reaction intermediate, can be utilized as a high-quality drilling fluid.
