Abstract: A method, a system, and a non-transitory computer readable medium for simulating a circuit are provided. The method includes generating a digital simulation file for the circuit that includes a block, generating a mixed simulation file for the circuit, generating a waveform file by executing the digital simulation file for a first time window of a simulation, determining a plurality of analog values for the block based on the waveform file, and executing, by a processor, the mixed simulation file for a second time window of the simulation with the plurality of analog values annotated to the block at a start of the second time window. The digital simulation file corresponds to the block in a digital view and the mixed simulation file corresponds to the block in an analog view.

Abstract: A hand-carry gravity-driven water filter with high throughput and water disinfection performance is formed. Membranes used for this water filter can be fabricated using electrospun method and non-solvent induced phase inversion method. A novel composite membrane structure (interwoven composite structure) was designed for further enhances water permeability and mechanical strength. The composite membrane can be composed of nanofibers with different diameter from the same polymer or different polymers. Membrane porosity and surface pore size can be controlled. Silver nanoparticles can be in-situ loaded on the surface of the membranes. The developed filter is effective for removal of a wide range of contaminants (e.g., pathogens, suspended solids and heavy metals). The purification process can be carried out under the drive of gravity (with an option for mechanically-enhanced filtration) without electricity.
