Abstract: Disclosed is a method for identifying fragile lines in power grid based on electrical betweenness, which comprises the following steps: constructing the power grid into a network diagram, sequentially removing lines in the network diagram, and sorting the electrical betweenness of each line from large to small; constructing a nonlinear model of complex network cascade failure considering overload and weighted edges, and respectively performing two ways of removing lines for sorted electrical betweenness, namely sequentially removing preset proportion lines and sequentially removing all lines until no new lines are removed in the network diagram; obtaining a change of generator-load power before and after each line removal, and evaluating a severity of power grid failure based on the change of generator-load power, thus completing an identification of power grid fragile lines.

Abstract: Devices and methods are described for reducing etching due to Galvanic Effect within a printed circuit board (PCB) that may be used in an electronic device. Specifically, a contact trace is coupled to a contact finger that has a substantially larger surface area than the contact trace. The contact finger is configured to couple the electronic device to a host device. The contact trace is electrically isolated from the rest of the PCB circuitry during a fabrication process by a separation distance between an exposed portion of the contact trace and an impedance trace. The contact finger and the exposed portion of the contact trace are plated with a common material to reduce galvanic etching of the contact trace during fabrication. The contact trace is then connected to the impedance trace using a solder joint.

Abstract: The present invention makes public a method and an apparatus for the revalorization of various organic waste, by means of physics and mechanics. The bubbles are produced and injected into the mixture in the sealed tank under depressure, then establish the movement of toric rotation in the vertical direction. The high-speed movement bubble carrying focused energy vigorously collide into the mixture, thus showing the Rheo-fluidizing effect (Shear thinning), decreasing the viscosity and depolymerizing long-chain molecules. This achieves active bacteria killing, separation, concentration and de-emulsification; the solution's advantage is applied to various organic residue, with short and efficient processing cycles, without producing unpleasant odors and is non-polluting, chemical free, at low temperature, low energy consumption, no GHG emission, preserving the microorganisms and nutrients of organic matter, and separating the pollutants such as the oils and fats.
