Concentrating solar power towers, which include a steam-Rankine cycle with molten salt thermal energy storage, is an emerging technology whose maximum e ectiveness relies on an optimal operational and dispatch policy. Given parameters such as start-up and shut-down penalties, expected price profiles, solar availability, and system interoperability requirements, we seek a profit-maximizing solution that determines start-up and shut-down times for the power cycle and solar receiver, and the times at which to dispatch various quantities of energy over a 48-hour horizon at hourly fidelity. - Jennifer DiCarlo


 

This figure shows a continuous steel caster.  Steel is batched and alloyed in the ladle which is then poured into an intermediate container known as the tundish.  The tundish is what feeds the oscillating mold to form the steel slab which is then pulled out by the rollers.  The rollers also support the slab while the outside shell solidifies until the entire cross section is solid.

Underground mining is commonly used to extract high value ore from deep underground for pro fit. In the design phase top-down open stope retreat mining, mine planners model the deposit as a discretized set of blocks, that are either are designated as pillars (and left in situ) or stopes (and extracted and processed). Safety is ensured by abiding by geotechnical restrictions on (i) the quotient of the area of a multiple-block stope region and its perimeter (i.e., the hydraulic radius), (ii) the length-to-width ratio of a pillar, (iii) the length of a stope relative to the length of an adjacent pillar, and (iv) the proximity of adjacent sheetlike groupings of blocks (called veins). We present a methodology consisting of (i) preprocessing, (ii) an integer program, and (iii) an iterative xing heuristic to determine the location of said pillars in order to maximize pro t while ensuring structural stability. Our solutions provided a feasible design, as opposed to the current solution and signi cantly reduces design e orts of the mining engineer, when applied to an African mine. - Levente Sipeki


As the demand for water within the South Platte Basin grows, we seek to mitigate the shortage that will ensue by the optimal placement of additional reservoir storage while including water transfers via pipeline.
