Abstract: Meteorology (later broadened to the term atmospheric sciences) received a much-needed boost in the United States during the period 1956 to 1962. It was primarily due to the efforts of concerned members of the National ...

Abstract: A recent article presented a convincing argument that all civil engineering professors should be registered professional engineers. This paper presents a similar argument from a faculty point of view. However, it focuses ...

Abstract: Pressure traces taken from microbarograms of first-order and research network stations are prepared for objective analysis on an electronic computer by placing paired numbers of time and pressure on punched cards. Data are ...

Abstract: Hysteretic responses of single mass reinforced concrete columns subjected to seismic biaxial base motions with constant and varying axial load are studied using the triaxial spring model. Comparisons are made with the ...

Abstract: For a tuned or symmetrically mistuned bladed disk assembly, several vibration modes are coupled only to the axial dynamics, which forces controllers to rely on an axial actuator. A control ...

Abstract: Ocean-monitoring tasks can be added to military over-the-horizon radars at modest incremental cost. A surface-wind-direction analysis for the Caribbean made with a U.S. Navy radar illustrates one capability of such a system. ...

Abstract: An analytical model is developed to simulate the hysteretic and stiffness degrading behavior of reinforced concrete members subjected to axial load and biaxial bending interaction. The model separates the member into two ...

Abstract: Repetitive controllers have been shown to be effective for tracking periodic reference commands or for rejecting periodic disturbances. Typical repetitive controllers are synthesized in temporal ...

Abstract: Position coordination of multi-axis mechanical systems is studied. Under the assumption that the coordination objective can be represented by smooth functions of the positions of the multiple ...
