A Geographic Information System (GIS)–based, lumped parameter water quality model was developed to estimate the spatial and temporal nitrogen–loading patterns for lower coastal plain watersheds in eastern North Carolina. The model uses a spatially distributed delivery ratio (DR) parameter to account for nitrogen retention or loss along a drainage network. Delivery ratios are calculated from tim...
The development of electromechanical actuators (EMAs) is the key technology to build an all-electric aircraft. One of the greatest hurdles to replacing all hydraulic actuators on an aircraft with EMAs is the acquisition, transport and rejection of waste heat generated within the EMAs. The absence of hydraulic fluids removes an attractive and effective means of acquiring and transporting the hea...
The degrees of freedom of multi-compartment mathematical models for energy metabolism of a neuronastrocyte complex may offer a key to understand the different ways in which the energetic needs of the brain are met. In this paper we address the problem within a steady state framework and we use the techniques of linear algebra to identify the degrees of freedom first in a lumped model, then in i...
