Abstract: An electrode for use in a lithium-ion battery. The electrode comprises a group IV-VI compound and a transition metal group VI compound on a three-dimensional graphene network. A major portion of the transition metal group VI compound is provided on top of the group IV-VI compound or in close proximity to it, whereby the molybdenum group VI compound contributes to the decomposition of a lithium group VI compound at the surface of the group IV-VI compound.

Abstract: A lithium (Li) ion battery includes a first electrode with a second electrode, and a shutdown polymer additive on an outer surface of the first electrode. The shutdown polymer additive includes at least two polyethylene layers, each polyethylene layer comprising a plurality of polyethylene microspheres. Each polyethylene microsphere is wrapped with carbon nanotubes. The polyethylene microspheres interconnect with each other such that the carbon nanotubes form a conductive network. The polyethylene layers are provided at predetermined areas of the outer surface of the first electrode.

Abstract: Method for selecting a sea clutter training area in polarimetric synthetic aperture radar input data. A sea clutter reference distribution for a pixel magnitude value is provided. Based on the input data, one or more parameters of the reference distribution and a global covariance matrix are computed. The pixels are grouped into blocks. A block that minimizes a cost function is pre-selected, the cost function being derived from empirical moments of the block and moments of the reference distribution. A goodness-of-fit is computed for the pre-selected block with respect to the reference distribution. If the goodness-of-fit is sufficient, the block is selected as sea clutter training area. Otherwise, the steps of preselecting and computing a goodness of fit are repeated.
