RISEigenstructure Assignment by Displacement–Acceleration Feedback for Second Order Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new technique for controlling the dynamic response of secondorder systems by means of combined displacement and acceleration feedback. The necessary conditions that guarantee the solvability for the ...
Parametric Approach for Eigenstructure Assignment in Descriptor Second Order Systems via Velocity Plus Acceleration Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this article, the problem of eigenstructure in descriptor matrix secondorder linear systems using combined velocity and acceleration feedbacks is considered. This is promising for better applicability in many practical ...
Pole Placement for Single Input Linear System by Proportional Derivative State Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the direct solution of the pole placement problem for singleinput linear systems using proportionalderivative (PD) state feedback. This problem is always solvable for any controllable system. The ...
Method of Fundamental Solutions without Fictitious Boundary in Elastodynamic Behavior Using Dual Reciprocity Method
Publisher: ASCE
Abstract: In this paper, a meshless method for analyzing the elastodynamic behavior of two-dimensional problems is introduced. The nonsingular method of fundamental solutions (NMFS) is combined with the method of particular solutions. ...
A Variational Boundary Element Formulation for Shear Deformable Plate Bending Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the derivation of a new boundary element formulation for plate bending problems. The Reissner's plate bending theory is employed. Unlike the conventional direct or indirect formulations, the proposed ...
The Potential of Vegetation in Reducing Summer Cooling Loads in Residential Buildings
Publisher: American Meteorological Society
Abstract: The potential of trees and other vegetation to reduce building cooling loads has been recorded in a number of studies but the meso- and microclimate changes producing such savings are not well understood. This paper describes ...
Incorporating Multiskilling and Learning in the Optimization of Crew Composition
Publisher: American Society of Civil Engineers
Abstract: The presence of multiskilled workers in a crew can increase the crew’s productivity through reducing inefficiencies and supervision requirements, while also providing on-the-job learning opportunities for single-skilled ...
