Abstract: Aspects of the disclosure are directed to predicting compute resource usage over time for various tasks in a multi-tenant compute cluster to allow for overcommitting the tasks on physical machines of the multi-tenant compute cluster. Overcommitting the tasks can result in hardware savings, as fewer physical machines are needed to run additional workloads. A machine learning model can predict the compute resource usage over time by predicting resource usage per task based on statistics of intervals of monitored task resource usages and combining the predicted task resource usages to generate a total predicted resource usage for a physical machine.

Abstract: The present disclosure discloses a Pichia kudriavzevii and a multifunctional complex microbial inoculant and use thereof, and belongs to the technical field of bioengineering. The Pichia kudriavzevii of the present disclosure has a degrading ability of lactic acid as high as 12.69 g·L?1, which is 2.04 times that of a type strain. At the same time, the strain can also metabolize ethanol and has an OD600 of 4.48 after fermentation in a sorghum juice medium at 30° C. and 200 rpm for 3 d. The Pichia kudriavzevii could completely consume 58 g·L?1 of glucose in the sorghum juice medium after 60 h of fermentation and produce 13.06 g·L?1 of ethanol. The Pichia kudriavzevii degrades lactic acid and can relieve a lactic acid pressure of a fermentation system and enable Saccharomyces cerevisiae to grow and metabolize to produce wine.

A first trench is formed in the active region. A first insulation layer is formed on a side wall of the first trench. A bottom portion of the first trench is etched to form a second trench. A gate oxide layer is formed on a side wall of the first insulation layer and a bottom portion and a side wall of the second trench. A barrier layer is formed at a bottom portion and portion of a side wall of the gate oxide layer. A metal filler layer is formed on an inner side of the barrier layer. The first insulation layer is removed to form a side trench. A second insulation layer is formed at a top end of the side trench. A sealed air spacer layer is formed.

Abstract: The application proposes a non-destructive testing method for the sealing degree of the small cigarette box packaging, which includes placing the small cigarette box to be tested in an airtight chamber, using a balance cabin to quickly form a stable negative pressure in the airtight chamber; The pressure change of the sealed chamber is continuously measured until equilibrium, and the data model is analyzed and established by using Darcy's law, Fick's diffusion law and the physical process of molecular kinetic theory. Through the non-destructive testing method for the sealing degree of the small cigarette box packaging of the present invention, the traditional destructive measurement (damaged small box packaging) for measuring the sealing degree of cigarette small box is changed into non-destructive testing; The test results have specific physical meaning; The test time of a single sample is reduced to ? of the time of destructive test.
