Voltage and VAR optimization for energy control
The topic of voltage optimization has been of recent interest to many researchers and is being considered by many utilities for implementation in their Energy Control Centers. Much of the past research has utilized linear programming incremental models or strictly gradient techniques. This research …

Dutch Disease in Australia: A Structural VAR Model
We applied a Structural VAR model to empirically investigate the adverse effect of positive growth shock in the resource sector on economic activity in a small open economy, like Australia. We observed the key eight variables important for explaining the evidence of Dutch disease over the period of …

^The^ causes of German unemployment: a structural VAR approach
… the help of Structural Vector AutoRegressive (SVAR) approach, this thesis aims at shedding more light on the role of macroeconomic shocks hitting the economy over time and their persistent effects due to structural rigidities in the labor market in accounting for the high unemployment. This work …

WRF-Var implementation for data assimilation experimentation at MIT
… project is to implement the WRF model with 3D variational assimilation (3DVAR) at MIT. A working version of WRF extends the scope of experimentation to mesoscale problems in both real and idealized scenarios. A state-of-the-art model and assimilation package can now be used to conduct science …

Grünkohl (Brassica oleracea var. sabellica): Untersuchungen zur Diversität verschiedener Sorten
Grünkohl ist besonders im Norden Deutschlands jedem ein Begriff und beliebt als wohlschmeckendes und traditionelles Wintergemüse. Doch Grünkohl ist nicht gleich Grünkohl. Das sollte im Rahmen dieser Arbeit schnell deutlich werden, als 12 kommerziell im Handel erhältliche sowie 12 alte ostfriesische …

Optimal Volt/VAR Control and Power Dispatch in Active Distribution Systems
… we address some of these challenges by proposing various problem statements along with new techniques to show how a distribution system with different MGs and DERs should work. These problem statements include economic dispatch, multi-objective economic-emission dispatch, economic-reliability …
