Abstract: Techniques for measuring vacuum pressure using a memristor element are described. A vacuum sensor can include a memristor element having a semiconductor substrate, a memristive material layer, and a conductive electrode. The off-state resistance of the memristor element can be sensitive to changes in ambient pressure at the element. The off-state resistance of the memristor element may also exhibit a well-defined increase at pressures below a threshold pressure. Measurement of the off-state resistance may be obtained with low power consumption and without changing the resistance or switching the state of the memristor element. The measurements may be used to both determine a leak rate of the ambient pressure within the volume of interest and determine if the sensor is exposed to vacuum pressure below the threshold pressure.

Abstract: Polymer flooding models for carbonate reservoirs and related methods include the trapping number effect on residual oil saturation. A method for predicting oil recovery from a reservoir using enhanced oil recovery techniques can include simulating the reservoir in a computer simulation (202). Injection of a fluid (204) can be simulated in the computer simulation and an enhanced oil recovery technique can be simulated to simulate the oil recovery from die reservoir (206).

Abstract: Methods and systems for implementing sedenion value neural network models are provided. A method includes obtaining, from a data store or a user device, values associated with a feature for which a value is to be determined. The method includes generating an input sedenion using the values and inputting the input sedenion to a sedenion value neural network (SVNN) model configured to generate an output sedenion using the input sedenion. The output sedenion may indicate a sedenion representation of the value to be determined. The method includes generating a sequence of real values using the output sedenion. The sequence may be or include the value. The method also includes outputting, to the data store or to the user device, the sequence of real values.

Abstract: A computer-implemented method of preparing an anonymised dataset for use in data analytics. The method includes the steps of: (a) labelling elements of a dataset to be analysed according to a labelling scheme; (b) selecting one or more labelled elements of the dataset to be replaced with a distance preserving hash; and for each selected element: (c) partitioning a data plane including the selected element into a plurality of channels, each channel covering a different distance space of the data plane; (d) hashing, using a cryptographic hash, data associated with the channel of the data plane in which the selected element resides, to form the distance preserving hash; and (e) replacing the selected element with the distance preserving hash.

Abstract: In this work is presented a method for fabrication of high-aspect ratio structures through spalling effect. The spalling is achieved through lithography, etching and sputtering processes, thus providing the flexibility to position the spalled structures according to the application requirements. This method has been successfully demonstrated for metal-oxides and metals. The width of the fabricated structures is dependent on the thickness of the film deposited by sputtering, where structures as small as 20 nm in width have been obtained.
