Carbon cycling in secondary tropical dry forest from species to global scales.
Tropical forests are important in the global carbon cycle but questions remain about the distribution of carbon stocks and the controls over carbon cycle processes in these forests. This is especially true with tropical dry forests which comprise as much as 43% of global tropical forests, but have …

An analysis of energy balance in a helicon plasma source for space propulsion
This thesis covers work done on the mHTX@MIT helicon source as it relates to the analysis of power losses. A helicon plasma is a rather complex system with many potential loss mechanisms. Among the most dominant are optical radiation emission, wall losses due to poor magnetic confinement, and poor …

Total-to-peak ratios of high purity germanium gamma ray detector
This study is concerned with the percentage of [gamma]-rays of a certain energy having their energy correctly measured by a high purity Germanium [gamma]-ray detector. The ratio between the total counts and the counts within the energy peak (total-to-peak ratio) is determined for seven energies …

Structural vibration damping using lightweight, low-wave-speed media
Incorporation of a low-density, low-wave-speed medium (LWSM) into a structure yields significant damping if the speed of wave propagation in the medium is low enough for standing waves to arise in it. In this thesis, we characterize wave propagation in low-density granular media and foams for use …

Improving complex enterprises with system models
Air Force sustainment operations are the focus of an intensive internal effort to improve performance and reduce costs. Past improvement initiatives have often failed to produce the intended results, and have caused performance to decline in some cases. Exploratory research was conducted at an Air …
