Geochemical and sedimentological investigations of Youngest Toba Tuff ashfall deposits
The ~ 73 ka ‘super-eruption’ of the Toba caldera in Sumatra is the largest known eruption of the Quaternary. The products of this eruption, the Youngest Toba Tuff (YTT), have been implicated in global and regional climate deterioration with widespread ecological effects. In this thesis I study the …

Long-range impacts of the ~74 ka Toba super eruption
The ~74 ka Toba super eruption (Indonesia) was the largest Quaternary volcanic event and, thus, has been a topic of debate regarding its possible impact on climate, environment, and eventually, early modern humans. This dissertation was aimed at improving our understanding of the Toba impact by …

One Church, Two States: Ethnicity Among the Toba Bataks in a Transnational Christian Community
This work also analyzes Toba Batak identity dilemmas derived from incompatibility of their indigenous culture with Christianity. Both the Indonesian and the Singaporean development ideologies support Christianity and represent it as appropriate for modernization while Toba Batak indigenous culture …

Toba Batak Marriage and Alliance: Family Decisions in an Urban Context (Kinship, Sumatra, Indonesia)
I examine the Toba Batak asymmetric alliance system from an interpretive perspective, arguing that structure is rooted in the context and social action. Detailed case study data on marriage decisions by middle-class families in Medan, Indonesia, demonstrate that alliance systems are more than the …

Similarity relations of wind waves in finite depth
… in finite depth based on Phillips (1958), Toba (1972) and Donelan et al. (1985) are tested using spectral measurements from Lake St. Clair. Assuming spectral similarity in wave number space relations between the energy, equilibrium parameters and peak wave number are derived. Using a …

Forcings on Coccolithophore Evolution and Assemblage Changes
… Sea for about 8–19 years after the ~74 ka Toba supereruption, best explained by cooling of the Asian landmass that strengthened the Indian winter monsoon. However, the coccolithophore assemblage after the Toba supereruption responded differently from the succeeding cold stadial, supporting …

Modeling wind forcing in phase resolving simulation of nonlinear wind waves
… evolution parameterizations and asymptote Toba similarity law. Our simulations resolve the detailed kinematics and the nonlinear energetics of swell, windsea and their fast transition under wind forcing. We explain the difference between measurements of initial growth driven by a linear …

Understanding the Impact of Large-Scale Power Grid Architectures on Performance
<p>Grid balancing is a critical system requirement for the power grid in matching the supply to the demand. This balancing has historically been achieved by conventional power generators. However, the increasing level of renewable penetration has brought more variability and uncertainty to the grid …
