Abstract: This paper provides an overview of the aircraft turbine engine control research at NASA Glenn Research Center (GRC). A brief introduction to the engine control problem is first provided with a description of the state-of-the-art ...

Abstract: Most of the hydrological models developed and used previously in sediment yield modeling are complex and lack general applicability. Moreover, the availability of sediment data for the development and calibration of such ...

Abstract: Waste disposal is a challenging environmental concern worldwide. Carbon-rich waste materials can be transformed into adsorbent and/or catalyst support to reduce treatment costs and promote waste recycling. In the present ...

Abstract: A generalized procedure has been advanced for path identification in complex multiloop interconnected directed networks. Reference to transportation networks has been made for the sake of specificity ...

Abstract: The effect of sustained load and hygrothermal environments on Mode I delamination behavior of T300/934 unidirectional graphite/epoxy laminates has been studied. Several double cantilever beam ...

Abstract: A brief literature survey of human factors engineering as applied to machine design is presented. The literature has been classified under the categories: (i) static and functional body dimensions, ...

Abstract: A systematic synthesis procedure is developed for ensuring an absence of limit cycles in nonlinear systems. Compensator parameter plots, subject to specified constraints, are generated in parameter ...

Abstract: This paper provides an improvement over the earlier theoretical analysis for a rigid, frictionless, cylindrical capsule moving parallel to the horizontal pipe wall (Garg and Round [1]) by taking into account...

Abstract: Linear spatial stability of the nonparallel developing flow in a concentric annulus shows that the asymmetric disturbance with an azimuthal wave number equal to unity is more unstable than the ...
