Abstract: A computer implemented method for managing a distributed battery arrangement, wherein the arrangement comprises a pool of battery assets (121-125), wherein the battery assets of the pool are individually owned. The method is performed by obtaining real time data relating to current state of the battery assets of the pool, wherein the current state of the battery assets of the pool comprises at least information about capacity and wear profile of the battery assets of the pool; and selecting one or more battery assets from the pool based on the obtained real time data to fulfil a capacity requirement for frequency balancing of electric grid (151).

Abstract: A computer implemented method of energy consumption management and scheduling of cell shutdown periods in a communication network. The method includes individually scheduling daily shutdown period for certain target cells of the communication network by performing the following for each target cell: collecting usage data from a monitored cell for a first period of time, wherein the target cell and the monitored cell operate on different frequency bands and serve at least partially the same geographical area; comparing the usage data with a threshold value to determine a low-load period in the monitored cell; and scheduling a shutdown period for the target cell during the low-load period in the monitored cell.

Abstract: A computer implemented method for identifying a stationary user device of a communications network. This is performed by obtaining (301) usage data from the communications network; analysing (302) the usage data to check whether a user device fulfils the conditions of a stationary user device; responsive to finding that the user device fulfils said conditions of a stationary user device, concluding (303) that the user device is stationary; and outputting (304) information about the user device being stationary for the purpose of further analysis and/or management of the communications network. The conditions of a stationary user device require that the amount of data transmission to or from the user device exceeds a first threshold, and that the user device has been connected to a predefined maximum number or fewer base stations or cells.

Abstract: Monitoring of a semiconductor manufacturing process. Wafer measurement data is obtained (301); Zernike polynomials are fitted (302) to the wafer measurement data to obtain representation of respective wafermap patterns; a knowledgebase of wafermap patterns is built (303) based on the respective coefficients of the Zernike polynomials; the wafermap patterns of the knowledgebase are grouped (304) to wafermap pattern groups based on the respective coefficients of the Zernike polynomials; and at least some of the wafermap pattern groups of the knowledgebase and the respective coefficients of the Zernike polynomials are used (305) for analyzing new wafer measurement data for the purpose of monitoring the semiconductor manufacturing process.

Abstract: A computer implemented method for evaluating effect of a change made in a communication network. The method is performed by comparing values of the performance indicator in a cell of interest before and after the change to obtain a first comparison result; comparing values of the performance indicator in a set of reference cells before and after the change to obtain a second comparison result; and evaluating the effect of the change made in the communication network based on difference between the first comparison result and the second comparison result.

Abstract: A computer implemented method for controlling call capacity in a mobile network. The method includes: activating a mass event mode in a first cell of a first base station, wherein the first cell is a high frequency band cell, and wherein operating in the mass event mode comprises: checking if any low frequency band cells are available in a first sector served by the first cell; and responsive to detecting that one or more low frequency band cells are available, switching, at least some, voice call connections of the users of the first cell to at least some of the available low frequency band cells.

Abstract: Analyzing measurement results of a target system. The analysis is performed by receiving a first matrix including first measurement results of the target system; training a matrix decomposition model with the first matrix to obtain a third matrix of normal or stable measurement results and a fourth matrix of anomalous or unstable measurement results; receiving a second matrix including second measurement results of the target system, wherein the second measurement results are later measurement results compared to the first measurement results; selecting from the third matrix a subset that matches with the second matrix; subtracting the selected subset from the second matrix to obtain a fifth matrix; outputting the fifth matrix or information derived from the fifth matrix for the purpose of evaluating performance of the target system.

Abstract: A computer implemented method for obtaining an autoencoder model for the purpose of processing metrics of a target system. The method includes obtaining a data set including metrics associated with the target system, the data set being intended for training the autoencoder for processing further metrics of the target system; masking the data set with a predefined mask configured to exclude certain parts of the data set; using the unmasked parts of the data set for training the autoencoder; masking reconstructed data from the autoencoder with the same predefined mask; using reconstruction error of the unmasked parts of the reconstructed data to update parameters of the autoencoder to obtain autoencoder model; using the masked parts of the data set for testing the autoencoder model; and providing the autoencoder model for processing further metrics of the target system.
