  • Publication number: 20210063188
    Abstract: A system optimizes an objective function by iteratively refining the objective function. The system evaluates an initial set of results for a set of initial candidates according to an objective function. The system generates a local model. The system identifies a plurality of new candidates. The system determines, for each new candidate, a prediction of whether the candidate violates a constraint. The system selects a new candidate based on the prediction for each of the candidates and updates the local model using the new candidate. The system identifies a potential optimal solution from the updated local model. The system distributes resources of a computing system according to the potential optimal solution.

  • Publication number: 20210064428
    Abstract: A transport service system comprises a plurality of drivers and riders over a plurality of cities. A resource allocation function using a plurality of variables associated with incentives that may be provided to the drivers and riders over the cities with an output describing a profitability of the system. The system evaluates an initial set of results for an initial set of randomized candidates according to a resource allocation function. The system generates a plurality of local models. Each local model is a Gaussian process posterior distribution over a trust region centered around a randomized candidate. The system samples a function from each distribution and identifies a candidate with an optimal result according to the sampled function. The system evaluates the best candidate chosen from among the identified candidates with the resource allocation function. The system then identifies an optimal solution from the evaluations and distributes resources according to the optimal solution.

  • Patent number: 8642811
    Abstract: The invention provides a method to produce primary diamines by catalytic conversion of diols having a linear main chain of from 4 to 31 carbon atoms into the corresponding diamines. The reaction is conducted in a liquid or supercritical phase and is catalyzed by a homogeneous ruthenium-containing complex. The primary diamines obtained may be suitable for polyamide syntheses.

  • Patent number: 6777914
    Abstract: In a method for determining the state of charge of rechargeable batteries by integration of the amounts of current flowing during charging and discharging, a first state of charge value LZA is determined by continuous integration of the rechargeable battery current. A second state of charge value LZB is determined by measurement of the no-load voltage U0 after receiving or supplying a defined amount of charge Q which is sufficient in order to leave the region of the mixed potential of the electrodes and to reach a no-load voltage of the rechargeable battery, and by comparison of this measured no-load voltage U0 with empirically determined no-load voltage characteristics for the rechargeable battery.

  • Patent number: 5074687
    Abstract: In a method for the manufacture of armatures from sheet-metal parts stacked in the manner of laminated inductors, predeterminately shaped openings or indentations (6) and corresponding coaxially opposite projections (8) are defined in and during the formation of the sheet-metal parts (1, 2, 3), the sheet-metal parts are stacked so that the projections (8) nestedly engage the shaped openings or indentations (6) of the adjacent sheet-metal part (1, 2, 3) and thereby provide form-locked mechanical connections between the parts, and the stack (11) of sheet-metal shapes is secured against loosening and disengagement of the form-locked mechanical connections (10) by cementing or thermal bonding or the like of the sheet-metal parts one to another.
