environmental sustainability. A ...
Characteristics of Water Surface Profile over Rectangular Side Weir for Supercritical Flows
Publisher: ASCE
Abstract: The supercritical flow over a side weir is a type of spatially varied flow with decreasing discharge. Most studies of side weir flows are limited to the estimation of the discharge coefficients, and less attention has been ...
The Effect of Porosity on Elastic Stability of Toroidal Shell Segments Made of Saturated Porous Functionally Graded Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research deals with the stability analysis of shallow segments of the toroidal shell made of saturated porous functionally graded (FG) material. The nonhomogeneous material properties of porous shell are assumed to ...
Axisymmetric Thermal Stresses of a Piezoelectric Poroelastic Circular Solid Plate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the steady-state thermoelasticity solution for a circular solid plate is made of an undrained porous piezoelectric hexagonal material symmetry of class 6 mm. The porosities of the plate vary through the ...
Adaptive Pneumatic Force Actuation and Position Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper an implementation of an adaptive control law for a pneumatic actuator is presented. Pneumatic actuators are of particular interest for robotic applications because of their large ...
Design of Controllers for Quadratic Stability and Disturbance Attenuation of Uncertain Systems
Publisher: The American Society of Mechanical Engineers (ASME)

Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the exact solution of the equation of transient heat conduction in two dimensions for a hollow cylinder made of functionally graded material (FGM) and piezoelectric layers is developed. Temperature distribution, ...
Actuator Saturation and Control Design for Buildings under Seismic Excitation
Publisher: American Society of Civil Engineers
Abstract: Efficient design techniques are presented for improving the response of seismic-excited buildings under actuators with limited capacity. Information regarding the actuator capacity and estimated peak ground acceleration ...
Vibration Suppression with Resettable Device
Publisher: American Society of Civil Engineers
Abstract: Novel low-power or semiactive devices are developed for vibration suppression applications. By manipulating the structural stiffness, the resisting forces generated by the devices are quite large and independent of velocity. ...
Scheduled Controllers for Buildings under Seismic Excitation with Limited Actuator Capacity
Publisher: American Society of Civil Engineers
Abstract: A new class of scheduled controllers is presented for improving the response of seismic-excited buildings under actuators with limited capacity. The controller is scheduled based on the response of the system on-line, to ...
