Needle length in young ponderosa pine (Pinus ponderosa Dougl. ex Laws var. ponderosa) was assessed for its ability to estimate site quality of afforested land in Neuquén, Argentina. The objective was to determine the best aspect on the tree, number of needle age classes, and number of trees that would...
This thesis looks at the third harmonic voltage response of a small incandescent lightbulb. The third harmonic voltage, or 3 omega (3ω) voltage, arises from applying a 1ω sinusoidal voltage across a resistive material. The 3ω voltage carries with it information about the thermal conductivity of the material. A lock-in-amplifier...
