A method for estimating the severity of generator unit outage and multi-terminal branch outage contingencies with respect to voltage collapse... Show moreA method for estimating the severity of generator unit outage and multi-terminal branch outage contingencies with respect to voltage collapse in large-scale electric power systems which includes the steps of estimating a post-contingency saddle-node bifurcation induced voltage collapse point of an electric power system following a set of generator unit outages and/or a set of branch outages and calculating a distance to collapse of said power system. The post-contingency voltage collapse point is determined by application of a nonlinear contingency screening method. Sponsorship: Illinois Institute of Technology United States Patent Show less

Show moreA process is provided wherein hemoglobin, a fragile material, is formulated into high hemoglobin content water-in-oil-in-water multiple emulsion while maintaining high yields and high oxygen exchange activity. A multiple emulsion of aqueous oxygen carrying material in oil in outer aqueous phase is suitable for provision of oxygen for oxygen transfer processes. A hemoglobin multiple emulsion in physiologically compatible oil in an outer aqueous saline solution is provided in sufficiently small droplet size to provide oxygen flow through blood vessels to desired body tissues or organs thereby providing a blood substitute.

Show moreA method for heat treatment of steel and a system thereof is provided. First the steel is austenitized at a suitable temperature and then the temperature is rapidly brought down to the austempering temperature. Here the cyclic austempering is carried out between two austempering temperatures by modulating the temperature with controlled heating and cooling and the controlled temperature modulation is obtained by controlling the temperature-time profile in a batch furnace or by controlling the zone temperatures in a continuous furnace. This method of cyclic austempering reduces the austempering time, reduces the energy consumption and emissions, enhances the productivity and reduces the process cost.

Show moreAn on-chip inductor device for Integrated Circuits utilizes coils on a plurality of metal layers of the IC with electrical connectors between the coils and a magnetic core for the inductor of stacked vias running between the coils. The magnetic core is made from a series of stacked vias which are deposited between each metal layer of the IC having a coil. The magnetic core desirably includes an array of magnetic bars comprising the magnetic core. The via material of the magnetic core may be both magnetic and electrically conductive. The magnetic and electrically conductive via material may also be used for the planar coil electrical connectors or other electrically conductive parts of the IC, or both, thereby lessening fabrication steps. Films of magnetic material may be formed at the ends of the inductor to provide a closed magnetic circuit for the inductor. A high Q factor inductor of small (e.g., transistor) size is thus obtained. The materials and processes which enable the on-chip inductor device are compatible with ordinary IC fabrication methods. Sponsorship: Illinois Institute of Technology United States Patent Show less
