The Problem

• Photovoltaic output power can be affected by many factors including clouds passing overhead.

• Utilities in generally prefer a guaranteed power delivery level over some specified power delivery period.

• Power delivered during peak demand hours is generally more valued by utilities. For the Desert Southwest this is in the summertime afternoons. For the local area this will be defined as 1-5 pm for the three summer months.

• While battery power can be adapted to this problem, large batteries to be expensive.

Energy Consumption In Large Wastewater Treatment Plants As A Function Of Wastewater Strength, Timothy Newell, Jacimaria R. Batista, Sajjad Ahmad, Walter Johnson

Wastewater treatment (WWT) is an energy-intensive process. Strict standards for discharge often require energy intensive advanced treatment technologies. As a result, the number of plants using advanced treatment has increased (Figure 1).

Rising energy costs and concerns about greenhouse gas generation present a major incentive for tracking energy usage of WWT. Energy usage in plant, for instance, typically represents 18 to 30% of the operational budget.

Water efficient fixtures are also increasing loadings of organic matter to plants while lowering or maintaining overall liquid flow. The increased loadings have a significant impact on energy consumption.

Thermal Conductivity Measurement With 3Ω Method Background And Synopsis Of Its Implementation, Fiifi Blankson

College of Engineering: Graduate Celebration Programs

ABSTRACT

Continued advances in nanostructured materials have made it necessary to develop materials with specific thermoelectric properties. The 3ω Method provides an accurate measurement of one such property, thermal conductivity. It will be used in this research to find high electrical conductivity alloys with low thermal conductivity.
