Abstract: A method of determining the center of loading of a rolling element includes providing a rolling element body and at least three load sensors. The sensors are each positioned within a bore of the rolling element body at a separate distance from a reference position. Load measurements are taken with each one of the sensors at various positions about the circumference of the bearing and the center of loading is calculated at each one of the positions to determine the variation in axial loading about the bearing circumference.

Abstract: The present disclosure belongs to the technical field of plant photoresponse and discloses a regression-based plant light environment-carbon sequestration benefit (a light response curve) determination method and system, and a medium. The method includes: performing data regression analysis by using various models; verifying data regression equations corresponding to the respective models; selecting a double hyperbolic curve regression model as an optimal one of the models; measuring red-blue light source by using a Li6400XT photosynthesis system; obtaining a light response curve through regression of the double hyperbolic curve; and obtaining corresponding formulas of light compensation (LCP) and a light saturation point (LSP) through regression. According to the present disclosure, a new double hyperbolic curve regression model is first adopted to fit the light response curve, so as to construct a more accurate photoresponse model.

Abstract: The present disclosure relates to systems, non-transitory computer-readable media, and methods for training and/or implementing machine learning models utilizing compressed log scene measurement maps. For example, the disclosed system generates compressed log scene measurement maps by converting scene measurement maps to compressed log scene measurement maps by applying a logarithmic function. In particular, the disclosed system uses scene measurement distribution metrics from a digital image to determine a base for the logarithmic function. In this way, the compressed log scene measurement maps normalize ranges within a digital image and accurately differentiates between scene elements objects at a variety of depths. Moreover, for training, the disclosed system generates a predicted scene measurement map via a machine learning model and compares the predicted scene measurement map with a compressed log ground truth map. By doing so, the disclosed system trains the machine learning model to generate accurate compressed log depth maps.

Abstract: Techniques for simulating fluid flow on a computer that involve a stable entropy solver are described. The techniques include simulating activity of a fluid across a mesh, the activity of the fluid being simulated so as to model movement of particles across the mesh, storing, in a computer accessible memory, a set of state vectors for each mesh location in the mesh, each of the state vectors comprising a plurality of entries that correspond to particular momentum states of possible momentum states at a corresponding mesh location, simulating a time evolution of entropy of the flow by collecting incoming set of distributions from neighboring mesh locations for the collision operation, calculating by the computer scalar values in each location, determining outgoing distributions as a product of the collision operation and addition of a heat source, and modifying the flow by the computer performing for a time interval, an advection of the particles to subsequent mesh locations.

Abstract: The present invention discloses a disruptive low capital and operational cost logistics system and method that provides for fast and massive delivery of e-commerce merchandise, including same day delivery, of thousands of items and packages, reducing the need for building, operating, or using multiple fulfillment warehouses located near the consumers as in traditional e-commerce logistics. The systems and methods of the present invention facilitate the logistics for e-commerce delivery processes, and also may allow at the same time reducing the use of massive quantities of cardboard packages that are used for protection and containment for e-commerce orders, being sustainably beneficial. This is achieved by the use of multibox packages that are configured to contain a set of products including orders from different consumers and not necessarily having individual packages for individual consumers, where such multibox packages are sorted at the origin in a Central Fulfillment Center.

Abstract: In an example data processing method, a data processing task is received, which includes a to-be-processed non-polynomial function and to-be-processed data corresponding to an independent variable of the non-polynomial function. A first linear transformation is performed on the to-be-processed data, so that an independent variable value corresponding to data obtained after the first linear transformation falls within a fitting domain of definition. The fitting domain of definition is an interval selected from a domain of definition of the independent variable of the non-polynomial function. A fitting polynomial function value is obtained based on the data obtained after the first linear transformation. The fitting polynomial is obtained by performing Chebyshev series fitting on the non-polynomial function in the fitting domain of definition. A second linear transformation is performed on the fitting polynomial function value based on the first linear transformation, and a value of the non-polynomial function is obtained.
