Building a wireless mesh networked real-time electricity metering system in an MIT dormitory
… rooms was 56.53 watts, which is equivalent to an annualized cost of $84.18 and emissions of 480 pounds of CO 2. The largest consumer used 28% of the total energy, while the bottom three consumers combined used only 26% of the overall energy. The seven rooms together demanded between 300-490 watts …

A Comprehensive Decision Support System(CDSS) for Optimal Pipe Renewal using Trenchless Technologies
… within a main. The increasing repair and damage costs and degrading services demand that a deteriorating water main be replaced at an optimal time instead of continuing to repair it. In addition, expanding business districts, indirect costs, and interruptions including protected areas, waterways …

The effects of variable operation on RO plant performance
… and design are optimized to minimize the total annualized cost of the plant. The operation and size are optimized for four different electricity price functions: constant, moderately fluctuating, highly fluctuating, and actual electricity prices. The results show that significant savings (1-7%) …

Role of Hydrogen in Industrial Decarbonization: A Case for Ammonia Industry in the United States
… Here, we evaluate the spatial variations in cost of the above electrically-driven ammonia process across the U.S. predominantly, for different scenarios of electricity supply as well as technology cost scenarios for 2030. Our approach goes beyond prior techno-economic assessments of …

Optimal scheduling, design, operation and control of reverse osmosis desalination. Prediction of RO membrane performance under different design and operating conditions, synthesis of RO networks using MINLP optimization framework involving fouling, boron removal, variable seawater temperature and variable fresh water demand.
… optimal RO network which will minimize the total annualized cost while fulfilling a given boron content limit. The effect of pH on boron rejection is investigated at deferent seawater temperatures. The optimal operation policy of RO system is then studied in this work considering variations in …

A Comparative Study of Cooling System Parameters in U.S. Thermoelectric Power Plants
… Information Administration. Additionally, the cost of water saved among different categories of power plants is calculated. In general, the conditions which cause cooling systems to withdraw less water are not necessarily the more expensive conditions, and vice versa. While not all the …

DFIG-Based Split-Shaft Wind Energy Conversion Systems
… is investigated to improve the performance and cost of the system and reduce the wind power uncertainty influences on the power grid. This system utilizes a lightweight Hydraulic Transmission System (HTS) instead of the traditional gearbox and uses a Doubly-Fed Induction Generator (DFIG) instead …
