Abstract: A computer system, product, and method are provided. The computer system includes an artificial intelligence (AI) platform operatively coupled to a processor. The AI platform includes tools in the form of a machine learning model (MLM) manager, a metric manager, and a training manager. The MLM manager accesses a plurality of pre-trained source MLMs, and inputs a plurality of data objects of a test dataset into each of the source MLMs. The test dataset includes the plurality of data objects associated with respective labels. For each source MLM, associated labels are generated from the inputted data objects and a similarity metric is calculated. The MLM manager selects a base MLM to be used for transfer learning from the plurality of source MLMs based upon the calculated similarity metric. The training manager trains the selected base MLM with a target dataset for the target domain.

Abstract: Methods, systems, and computer readable media for utilizing an augmented neural network are disclosed. In one embodiment, the method includes utilizing a neural network (NN) pre-processor to convert generic coordinates associated with a dynamical system to canonical coordinates, concatenating a Hamiltonian neural network (HNN) to the NN pre-processor to create a generalized HNN, and training the generalized HNN to learn nonlinear dynamics present in the dynamical system from generic training data. The method also includes utilizing the trained generalized HNN to forecast the nonlinear dynamics, and quantifying chaotic behavior from the forecasted nonlinear dynamics to discover and map one or more transitions between orderly states and chaotic states exhibited by the dynamical system.

Abstract: An ultrasonic cleaner apparatus with an opening mechanism including a plurality of lugs preferably formed on a top surface of the apparatus, a lid enclosing the apparatus and resting on the lugs when the lid is in a closed position, and a rim formed exterior to the lugs, wherein the lid is secured in an open position between two or more of the plurality of lugs and the rim. A drain assembly coupled to the ultrasonic cleaner provides an advantageous configuration for dispensing cleaning and/or sterilizing fluid and the like from the apparatus.

Abstract: A package for generally circular sandwiches has two semi-circular pockets or recesses provided with flanges about the open edge of each. The flanges are connected by a hinge to facilitate closing and opening of the package.

Abstract: A foamed plastic food tray having a cover of the same material hinged to one side of the tray, is formed with a simple, secure latch constituted by a slotted portion of a strengthening rim on the periphery of the tray and an outwardly projecting flute with a flared out terminus on the front of the cover.

Abstract: A rectangularly shaped tray comprising a bottom product-supporting wall and up-standing side and end walls. The bottom product supporting wall is characterized by being elevated at its center portion, such as is provided by a quadrilateral pyramid-like bottom product-supporting wall with the apex of said quadrilateral pyramid being at the center portion of the bottom wall and at an elevation higher than the horizontal plane of the bottom of the four corners of said tray, whereby, when the commodity to be packaged is placed in the tray, the weight of said commodity presses the bottom wall of the tray downwardly resulting in the longer sidewalls of the tray being pulled inwardly.

Abstract: A meat tray of thermoformed plastic foam is provided with high side walls of sufficient stability to retain cut pieces by vertical flutes in the side walls and at the corners.

Abstract: Thermoformed cups, having elements adapted to provide a stable handle, which are nestable in a small space, the handle including a tab extending radially from the brim of the cup and a hinged flange at each side of the tab. To form the handle the flanges are turned down and are retained by shoulders of a recess in the upper surface of the cup. Weight of liquid in the cup causes the flanges to bear against the side of the cup to afford stability in addition to that resulting from retention by said shoulders.

Abstract: Stability of a thermoformed foam meat tray, especially to overwrapping by machine, is enhanced by a circumferential flange of the side walls of generally V-shaped cross section to terminate at approximately the plane of the bottom of the tray. Full nestability is afforded by upper surfaces of the flange at an angle to each other smaller than the corresponding angle between lower surfaces of the flange.

Abstract: A self-draining saucer is provided by combination of two concave discs (saucer shape). The lower disc has a central well defined by a depressed central bottom and circular wall. The upper disc is formed such that its bottom convex surface generally follows the concave upper surface of the lower disc. A vertical surface on the under side of the upper disc frictionally engages a similar surface inside the lower disc to retain the pair. Holes are provided through the top disc above the well in the lower disc for drainage of spilled liquid into the well. The combination is easily formed of thermoplastic resin and assembled on standard thermoforming machinery.

Abstract: A packaging tray, especially adapted for the containment of moisture containing food products such as meat, poultry and fresh produce comprising a bottom supporting surface having a plurality of spaced apart liquid entrapping recesses. The individual recesses have a larger cross-sectional area at their base than at their top.

Abstract: A tray for food and beverages in which the beverage cup recesses are adapted to retain differing size cups by reason of an arcuate projection from the bottom at one side of such recess.
