Abstract: Techniques and solutions are provided for database testing. In particular, aspects of the present disclosure facilitate “automatic exploration” of testing of database features, such as database commands. In particular, test definitions can be created for particular database features, where a test definition can have variants. Different test definitions can be combined into a composite test, which can include different variants for different tests. An executable test can be created that allows a database to execute a composite test. The present disclose also provides techniques and solutions for analyzing test results, particularly when voluminous test results are returned. In one example, test results for multiple iterations of a test can be compared. A change in test results, for example, can cause a test result to be flagged for further review. The composite tests, or result analysis techniques, can help provide better testing of database software to help identify software errors/bugs.

Abstract: A capillary type multi-jet nozzle is provided for fabricating high throughput nanofibers by an electrospinning technique. The capillary type multi-jet nozzle includes a cap system with one or more pores and a crew system with a screw groove system. The cap system and the crew system are connected through a cap and crew system. The pores in the cap system are customized in count based on a requirement. The angle between the pores is reduced to make multiple non-interfering and non-hindering jets in less time. A TEFLON® gasket is used for proper tightening and sealing of the cap system and screw system. The cap system includes knurling at an outer surface for grip. The capillary type multi-jet nozzle is made of a conducting material to with stand a high voltage and is fabricated using micro-machining process.

Abstract: An electronic gaming system including a memory device with instructions stored thereon and a processor in communication with a plurality of electronic gaming devices and the memory device is described. The instructions, when executed by the processor, cause the processor to receive digital wallet registration data including a digital wallet ID, determine that the digital wallet registration data is associated with a first player account, and store a digital wallet flag in the first player account. The instructions also cause the processor to, upon receipt of player data based on a card-in event, determine that the player data is associated with the first player account, determine that the digital wallet flag is stored in the first player account, and cause access to the digital wallet to be provided.

Abstract: Embodiments of the present invention provide a delivery enclosure configurable onto a door or like platform. The enclosure includes sections forming the pair of side covers, the top cover, the bottom cover, wherein each of the sections is sized such as to enable collapsing of one section over the successive section, a scissorian assembly comprising at least two arms configured onto each of the pair of side covers connecting the sections together, a handle operationally connected to one of the arms on each of the pair of side covers, wherein a pull of the handle by a resident enables the enclosure to attain at least one of an expanded configuration and a collapsed configuration, and an electronic locking system provided on the front cover for securely locking one or more deliveries within the secure compartment.
