(Virginia Tech, 1994)
An experimental auger-boom-type fertilizer distributor with automatic control
(Virginia Tech, 1964-05-06)
Software Architecture Considerations for Facilitating Electric Power System Planning Incorporating a Variety of Design Categories
(Virginia Tech, 2012-03-01)
This work investigates some of the features of existing software applications for electric power system planning as well as some of the limitations that keep these applications from being more frequently used in distribution ...
Evaluation of shallow-placed low pressure distribution systems in soils marginally suited for on-site waste treatment
(Virginia Tech, 1990-06-14)
Two shallow-placed low pressure distribution (LPD) systems were evaluated in soils that were marginally suited for a conventional on-site wastewater disposal system (OSWDS) because of low hydraulic conductivity and shallow ...

Singular optimal atmospheric rocket trajectories
(Virginia Tech, 1986-10-05)
<p>Singular subarcs arise in quite a few problems of flight dynamics. The present study is devoted to the specific problem of ascent and acceleration of a vehicle in atmospheric flight in which a variable-thrust arc forms ...
Integrated urban transportation and land use modeling by application of system dynamics
(Virginia Tech, 1995-01-16)
The spatial allocation of land uses and vehicle route selection within an urban network are both dependent upon travel times between zones in an urban region. These location and accessibility components form the basis of ...
A prevention of significant deterioration case study
(Virginia Tech, 1993-02-05)
<p>The PSD permitting of new sources has drawn increasing public and governmental opposition. Much of the opposition is due to heightened environmental awareness. The issues are further compounded by inherent ...
