Abstract: Disclosed in the present invention is a method for preparing a tertiary amine by using a secondary amine as a raw material. The method comprises a step of reacting a secondary amine that serves as a raw material with an acid to generate a proton-type ionic liquid, and a step of reacting the proton-type ionic liquid with an aldehyde under the action of a reducing agent to generate a tertiary amine. The secondary amine is an aliphatic secondary amine and/or an aromatic secondary amine and/or a cyclic secondary amine; the acid is selected from one of or a combination of several of an organic carboxylic acid and an inorganic acid; the aldehyde is a monoaldehyde, a dialdehyde or an aldehyde polymer; and the reducing agent is selected from one of or a combination of several of formic acid, sodium formate, oxalic acid, sodium oxalate and triphenylsilane.

Abstract: Performing a three-dimensional (3D) reconstruction process of a set of selected image frames. In some instances, a plurality of sequential image frames that are extracted from a video file (including video content created through the use of Augmented Reality) are converted into a grayscale format. Once these image files are converted to a grayscale format, a two-dimensional (2D) entropy process is performed that is ultimately used to create a set of user-defined clusters, with each of these user-defined clusters being associated with at least a sub-set set of the grayscale frames. After a cluster is selected, a 3D reconstruction process is performed on the frames associated with the selected cluster.

Abstract: Some embodiments provide a method for configuring logical routers of a logical network. The logical routers are implemented in a Kubernetes cluster as a first set of Pods that each perform logical forwarding operations for the logical routers and a second set of Pods that each perform L7 service operations for a respective logical router. From a Kubernetes control plane component, the method receives a notification that the first set requires scaling to include an additional Pod. The first-set Pods process data messages between the logical network and external networks. Within the network management system, the method defines at least one new interface for processing data messages between the logical network and external networks. The method configures the at least one interface on the additional Pod to communicate with external physical routers to receive traffic from the external networks and send traffic to the external networks.
