RISData-Driven Control Allocation for Overactuated Linear Time-Invariant Systems by Exploiting Sparsity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This paper proposes a data-driven control allocation (CA) scheme for input-redundant linear time-invariant systems. Contrary to the existing literature, the present work is built on a static state-feedback ...
Theoretical Load-Transfer Curves along Piles Considering Soil Nonlinearity
Publisher: American Society of Civil Engineers
Abstract: Soil stress-strain behavior is highly nonlinear and considerably influences the performance of a foundation. The response of single piles under axial load can be predicted from the load-transfer, or t-z, curve. This paper ...
LeaderBased Consensus in Directed Networks of Homogeneous Positive Agents With Multiple Inputs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the nonzero finite positive state consensus problem of leaderfollowing multiagent systems (MASs) connected over a directed network is investigated. The multiagent network consists of homogeneous linear ...
Applicability of Clay Soil Stabilized with Red Mud, Bioenzyme, and Red Mud–Bioenzyme as a Subgrade Material in Pavement
Publisher: American Society of Civil Engineers
Abstract: The present work evaluates and compares the performance of clay soil stabilized with red mud, bioenzyme, and red mud–bioenzyme as a subgrade material in pavement construction. Finite-element simulations have been performed ...
Identification of Tool Life Stages and Redressing Criterion for Polycrystalline Diamond Micro-Grinding Tools Using a Machine Learning Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interactions of wear debris at the tool-workpiece interface in micro-grinding are quite random which leads to considerable variability in the working life of similar tools. It is not possible to capture the effect of wear ...
Design of Gusset Plates and Interface Welds of SCBF Systems with Braces Buckling In-Plane
Publisher: American Society of Civil Engineers
Abstract: The design of connections of gusset plates, beams, and columns of concentrically braced frame systems is typically based on the forces generated by brace actions without considering the frame actions. This may result in ...
Synthesizing Negative-Imaginary Systems With Closed-Loop H∞-Performance Via Static Output Feedback Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper develops an algorithm for synthesizing negative imaginary (NI) systems with a specified H∞-norm bound by exploiting the convex relaxation technique in the static output-feedback (SOF) control design framework. ...
Geotechnical and Microstructural Mechanisms Associated with Valorization of Waste Phosphogypsum in Lime-Treated Expansive Soil Stabilization
Publisher: American Society of Civil Engineers
Abstract: Abstract In the present study, phosphogypsum (PG), a by-product from the fertilizer industry,
has been utilized to stabilize expansive soil. In order to enhance the pozzolanic
activity of PG stabilized soil, 3% and 6% of ...
Pasternak Model for Oblique Pullout of Inextensible Reinforcement
Publisher: American Society of Civil Engineers
Abstract: An analysis is presented for evaluation of the pullout capacity of sheet reinforcement subjected to oblique pullout force considering that the subgrade soil is represented as a two-parameter linear-elastic Pasternak model ...
Cyclic Behavior and Liquefaction Potential of Indian Pond Ash Located in Seismic Zones III and IV
Publisher: American Society of Civil Engineers
Abstract: In the present study, cyclic behavior and liquefaction potential of pond ashes collected from Talcher, Panki, and Panipat ash embankments located in seismic zone III and IV have been studied. Cyclic triaxial tests were ...
