摘要:
A nonaqueous ink composition for an ink jet and a method of manufacturing ink comprising the same are provided. The nonaqueous ink composition for the ink jet includes: a glycol ether acetate solvent represented by a specific chemical formula; and a polypropylene glycol binder represented by a specific chemical formula. The nonaqueous ink composition for an ink jet has dynamic viscoelasticity obtained by a chemical interaction between the solvent and the binder, exhibits excellent print quality and is capable of high-speed printing.

There are provided a printed circuit board and a manufacturing method thereof. The manufacturing method of a printed circuit board includes: preparing a substrate having active regions and non-active regions, the non-active regions being formed on edges thereof; printing resists on dummy portions corresponding to the non-active regions of the substrate by using an inkjet printing method; curing the resists; and performing plating on the active regions of the substrate. The resists are masked on the dummy portions corresponding to the non-active regions of the substrate to prevent plating from being performed on the dummy portions, thereby reducing manufacturing costs.

Disclosed is a method of predicting user's position. This method comprises, creating information on a plurality of location clusters by processing a plurality of position data for a user with a probability based clustering algorithm; receiving a current position data of the user and determining a first location cluster to which the current data is mapped among the plurality of location clusters; and creating second information related to a probability that the user moves from the first location cluster to a second location cluster among the plurality of location clusters. The position data is a data tuple including latitude, longitude, and time. For all the plurality of location clusters, the information includes a determined representative position value of each of the location clusters.

Provided is a method for predicting location of an object by using a learning model which includes an input layer, a hidden layer, and an output layer each including one or more nodes, that are associated with each other by a weight. When a definitive time value is input to the input layer, the output layer is configured to output a probability value that the object is located at a specific place.
