Abstract: A multifunctional vacuum sealing machine which includes a shell, and a vacuumizing device and a sealing device which are arranged in the shell, wherein the sealing device includes a hot welding device; cross sealing can be performed at a connector position twice, thus forming a completely-closed sealing line; and during vacuumizing, while a bag to be vacuumized is clamped and sealed by an upper cavity and a lower cavity, the bag is punched by a cutter head in the upper cavity, the bag is vacuumized, a punching position is in a closed area surrounded by one sealing line with the adjacent first heating wires and the second heating wire or in a closed area surrounded by the first heating wires and the second heating wires, and after vacuumizing, an opening is sealed at an original position, so that it is guaranteed that air cannot enter the vacuumized bag during sealing.

Abstract: Traditional approaches to predicting aircraft trajectories using kinematic models cannot work due to the complexity of the approach maneuver including flaps/slats, landing gear, ATC vectors, winds, and other traffic. The methods and systems disclosed can utilize Big Data Analytics (e.g., massive amounts of data of flights on each approach) to nowcast the approach stability given the state of the flight prior to the 1000?/500? check points.

Abstract: A storage system for efficiently storing samples in tubes or bottles in an upright freezer is disclosed. A rack has at least one drawer—the drawer slides out for high accessibility. Tubes or bottles may immediately be stored or retrieved without using boxes. The drawer may be fitted with a removable top plate with at least one hole. Into the hole, an insert may be placed for stabilizing tubes of different diameter and shapes and for storing other samples such as cryo-vials and slides. More importantly, the system can be easily configured for storing tubes, bottles, boxes, or any combination thereof. In the prior art, bottles and tubes are stored in boxes which are then placed in the drawer. Moreover, bottles and tubes are stored separately. Boxes must be outfitted with cell dividers in order to store tubes, and only tubes of the same diameter can be stored in the same box.
