Abstract: A method of reconstructing an electron microscopy image of size [Mx N] pixels of a first sample, the method implemented by a computer comprising a processor and a memory, the method comprising: providing a set of pre-learned dictionaries, including a first pre-learned dictionary including a set of p1 atoms; acquiring a sparse set of S acquired sub-images, including a first sub-image of size [a×b] pixels wherein a, b?[2, min {M,N}], of the first sample; and reconstructing the electron microscopy image of the first sample using the sparse set of S sub-images of the first sample and the set of pre-learned dictionaries.

Abstract: A method of simulating an electron microscopy image of a sample is described. The method implemented by a computer comprising a processor and a memory. The method comprises: obtaining parameters of the electron microscopy, attributes of the sample and respective thresholds of one or more target properties of the simulated electron microscopy image; and computing the simulated electron microscopy image of size [M×N] pixels of the sample using the obtained parameters of the electron microscope and the obtained attributes of the sample, according to the obtained respective thresholds of the one or more target properties of the simulated electron microscopy image.

Abstract: A method of operating a mobile cleaning robot can include navigating the mobile cleaning robot within an environment. A vacuum system of the mobile cleaning robot can be operated to ingest debris from the environment Whether a dispense condition is satisfied can be determined. Fluid can be dispensed from the mobile cleaning robot when the dispense condition is satisfied.

Abstract: A flue connection system for an appliance provides a flue connection member. The flue connection member defines an aperture and includes an extending member. The flue connection member is configured to be coupled to a flue duct and an appliance, including a fireplace. An appliance connection member may also be provided for attachment to the appliance. The flue connection member and the appliance connection member are configured to be coupled to one another with the flue connection member positioned in contact with the appliance connection member.
