Abstract: The present disclosure provides a method for interconnecting a data lake and a relational database, including the following steps: S1: adding a data source class of a relational database to a data lake; S2: matching and using, by the data lake, a data source class of the relational database; and S3: determining and loading a corresponding driver according to the data source class, so as to connect the corresponding relational database. By cascading a data source registering configuration file, a relational database configuration file and a driver package catalog in a parameter passing method, when the data lake is started, a specific database to be used is designated unnecessarily, but a corresponding database is used directly. The configuration file is also traversed unnecessarily, but the user acquires configuration information as required in the parameter passing method.

Abstract: Logo candidates for a specific ISO data can be identified from external resources based on the enriched merchant data. Low quality images of the logo candidates are filtered out with image analysis including entropy ratio evaluations of the logo candidates. Also, the logo candidates are processed with high quality filtering including classification of the logo candidates with a deep learning classifier for distinguishing logos from non-logos. A logo from the logo candidates is selected to associate with the ISO data packets. A display having the selected logo associated with a transaction of the ISO data packets can be generated for display to users.

Abstract: A vehicle curtain capable of being used in double-layer includes an outer mesh cloth, an interlayer plain cloth, and an inner covering plain cloth. The outer mesh cloth and the inner covering plain cloth are respectively arranged on an outer side and an inner side of the interlayer plain cloth, and an edge of the outer mesh cloth is disposed with several mounting connection blocks. The interlayer plain cloth includes an upper interlayer plain cloth and a lower interlayer plain cloth, the upper interlayer plain cloth is sewn and connected to the outer mesh cloth, and the lower interlayer plain cloth and the upper interlayer plain cloth are movably connected. By using a double-layer structure, a user can open and close the lower interlayer plain cloth through a guide rail or a zipper to realize semi shading and full shading functions of a vehicle window thereby greatly improving user's experience.

Abstract: Implementations of semiconductor clips may include a die attach portion coupled to a step portion, a lead attach portion directly coupled to the step portion, a first alignment feature directly coupled to a first side of the lead attach portion, and a second alignment feature directly coupled to a second side of the lead attach portion. The second side may be opposite the first side. The lead attach portion may be in a plane substantially parallel with a plane formed by the die attach portion.

Abstract: A rapid synthesis method of a small-crystal-grain ZSM-5 molecular sieve, the method comprising: preparing a mixed silicon-aluminum glue solution, placing the solution in a crystallization kettle for low-temperature nucleation, enabling high-temperature crystallization growth of the solution, and obtaining a crystallization product, namely, a small-crystal-grain ZSM-5 molecular sieve, the nucleation temperature being 60-120° C., nucleation time being 1-3 hours, a crystallization growth temperature being 150-170° C., and crystallization growth time being 1-3 hours. The method is easy to operate, and has a short operation time, thus being able to complete within 6 hours; in addition, the product has uniform grain sizes, is in a mono-dispersed state, and has a high crystallization degree to a submicron degree.

Abstract: A method for directly preparing an empty shell type small grain ZSM-5 molecular sieve. The method comprises: uniformly mixing and stirring an organic template agent, a silicon source and water; dripping an aqueous solution of an aluminum source into the mixture; preserving room temperature, and continuously stirring for a period of time; and performing hydrothermal crystallization, and washing, drying and roasting the obtained product to obtain the molecular sieve.
