An Accurate and Efficient Approach to Statistical Simulation for Large-Scale Analog Circuits
(1992)
A systematic approach to statistical simulation for large scale analog circuits is presented. The statistical model takes into account mismatch between devices due to variations in the process and noise, as well as interdie ...
A Stochastic Modeling for the Characterization of Random Tool Motion during Machining
(1992)
This paper presents the development of a new stochastic approach to characterize random tool motion during machining. The complexity of cutting mechanism is represented by a random excitation system related to physical ...
Bifurcations, Chaos and Crises in Power System Voltage Collapse
(1992)
Bifurcations occurring in power system models exhibiting voltage collapse have been the subject of several recent studies. Although such models have been shown to admit a variety of bifurcation phenomena, the view that ...
Jacobian and Stiffness Analysis of a Novel Class of Six-DOF Parallel Minimanipulators
(1992)
The Jacobian and stiffness matrices of two types of novel, six- DOF parallel minimanipulators are derived. A minimanipulator consists of three inextensible limbs, each of which is driven by a two-DOF driver. Bilinear stepper ...
Design, Verification and Implementation of Rule Based Information Systems for Integrated Manufacturing (INSIM)
(1992)
Full control and management of information flow in an automated factory has not yet been achieved, mainly because of the data inconsistencies and lack of established functional relationships among different manufacturing ...
Analysis of Surface Quality in Machining of Metals and Advanced Ceramics
(1992)
Of all the processes used to shape metals, it is machining in which the conditions of operation are most varied. Good dimensional accuracy and surface quality from machining processes should be maintained such that the ...
Automated Generation of Group Technology Codes from a PDES Product Information Model
(1992)
The design and implementation of an automated system that generates group technology (GT) codes for microwave modules (MWM) is presented. An established GT coding scheme (MICLASS) was employed to capture the mechanical ...
On the Effect of Constraint Softening on the Stability and Performance of Model Predictive Controllers
(1992)
The presence of constraints in the on-line optimization problem solved by Model Predictive Control algorithms results in a nonlinear control system, even if the plant and model dynamics are linear. This is the case both ...
Kinematic Synthesis of Tendon-Driven Manipulators with Isotropic Transmission Characteristics
(1992)
This paper presents a methodology for kinematic synthesis of tendon-driven manipulators with isotropic transmission characteristics. The force transmission characteristics, from the end-effector space to the actuator space, ...
On the Effects of the Initial Condition in State Estimation for Discrete-Time Linear Systems
(1992)
We consider the one-step prediction problem for discrete-time linear systems in correlated Gaussian white plant and observation noises, and non-Gaussian initial conditions. Explicit representations are obtained for the ...
