  • Patent number: 11455238
    Abstract: Methods and systems are presented for testing software applications in a production-like environment that simulates real-world failures of production environments. A production environment has production applications and databases configured to process user requests from users for conducting transactions with a service provider. A testing system provides an intermediate interface that enables a software application operating in the test environment to access at least one of a production application or a production database. The intermediate interface can be configured based on different failure configurations to simulate production component failures in the production environment. Failure injection and randomized failure modes can be employed, including for network-related failures (latency, dropped packets, connections, etc.) that might occur in the production environment.

  • Patent number: 11454594
    Abstract: The invention discloses a method for identifying frostbite condition of grain seeds using the spectral feature wavebands of the grain seed embryo hyperspectral images. At first, hyperspectral image of the grain seed in the embryo side is collected, and the hyperspectral image in the embryo region of the grain seed is obtained. Then the average spectra is calculated and the wavebands containing noise are eliminated, the spectral feature wavebands are extracted by using related algorithm and the spectra value corresponding with the waveband is obtained. Next, the feature waveband spectral value and the category label of the known frostbite category grain seed are input into the classification model for obtaining the optimal training classification model. Finally, the feature waveband spectral value of each unknown frostbite category grain seed is input into the established model, the frostbite condition of seed is identified.
