Abstract: The embodiments of the present disclosure provide systems and methods for managing inventory placement, comprising a memory storing instructions and at least one processor configured to execute the instructions. The processor may be configured to receive an identifier of a product for inventory placement, and determine, based on historical shipment data stored in a database, a region with the highest customer demand for the product. The processor may predict, using a machine learning algorithm, a product tag associated with the product based on at least a temperature associated with the region with the highest customer demand for the product. The processor may further modify the database to assign the product tag to the product identifier, and assign the product for placement in a fulfillment center. The fulfillment center may be associated with a fulfillment center tag corresponding to the product tag assigned to the product.

Abstract: Disclosed herein are systems and methods for product registration and validation in a retail environment. The system may comprise a memory storing instructions and one or more processors configured to execute instructions to perform operations. These operations may comprise receiving a request from a user device for a product registration template for a product category; retrieving metadata relating to the product category from a first database; generating a product registration template from the metadata; sending the product registration template to the user device; receiving product properties for the one or more products through the user device utilizing the product registration template; validating the received product properties against a predefined schema; storing the validated product properties in a second database; and registering the one or more products on the web server.

Abstract: Language interoperability between source code programs not compatible with an interprocedural static code analyzer is achieved through language-independent representations of the programs. The source code programs are transformed into respective intermediate language instructions from which a language-independent control flow graph and a language-independent type environment is created. A program compatible with the interprocedural static code analyzer is generated from the language-independent control flow graph and the language-independent type environment in order to utilize the interprocedural static code analyzer to detect memory safety faults.

Abstract: The present disclosure provides a method for measuring an angle and a distance. The method includes: at an initial position, after a laser emitting device aligns with a laser receiving device, recording a first angle and measuring a first distance between the laser emitting device and the laser receiving device; and moving the laser receiving device from the initial position to a first position, and after the laser emitting device realigns with the laser receiving device, recording a second angle and measuring a second distance between the laser emitting device and the laser receiving device. The method for measuring the angle and the distance creatively records the corresponding angle and distance at different positions, respectively, such that the position of the laser receiving device relative to the laser emitting device is accurately determined.
