A Parallel Manipulator with Only Translational Degrees of Freedom
This report presents a novel three degree of freedom parallel manipulator that employs only revolute joints and constrains the manipulator output to translational motion. Closed-form solutions are developed for both the ...
Structural Optimization in a Distributed Computing Environment
This report presents the formulation and testing of a Feasible Sequential Quadratic Programming (FSQP-DIS) optimization algorithm customized to a Distributed Numerical Computing environment (DNC). DNC utilizes networking ...
Domain-Driven Reconfiguration in Collaborative Virtual Environments
When virtual environments (VE) collaborate to create a shared virtual world, events occur that can have catastrophic effects on that virtual world. These events can be system events, such as the loss of a host or a network ...
Adaptive Selectivity Estimation Using Query Feedback
A Brief Guide to C and C++ for Fortran or Basic Programmers
This paper introduces C and C++ programming for learners who already have some experience in another language such as Fortran or Basic. It explains basic syntax, dynamic space allocation, structures, classes, constructors ...
Study of Human Laryngeal motion through Mathematical Modeling
The research presented in this dissertation concentrates on the motion of the arytenoid cartilages of the human larynx. Quantitative measurement and analysis was performed on the anatomy and motion of the cricoarytenoid ...
An Information Architecture to Support the Visualization of Personal Histories
This paper proposes an information architecture for personal history data and describes how the data model can be extended to a runtime model for an intuitive visualization using graphical timelines. Our information ...
Mixed H2 /H∞ Optimization: A BMI Solution
The mixed H2 /H∞ problem arises as one means to achieve robust good performance for a controlled linear time-invariant system. The idea is to achieve H2 optimal performance subject to an H∞ bound as robustness. It has been ...
A Note on the Positive Definiteness of BFGS Update in Constrained Optimization
This note reviews a few existing methods to maintain the positive definiteness of BFGS in constrained optimization, and their impacts on both global and local convergence. The boundedness of the matrix from above is also ...
Longitudinal and Transverse Cross Sections in the 1H(e,e′K+)Λ Reaction
(American Physical Society, 1998-08-31)
The 1H(e,e′K+)Λ reaction was studied as a function of the squared four-momentum transfer, Q2, and the virtual photon polarization, ɛ. For each of four Q2 settings, 0.52, 0.75, 1.00, and 2.00 (GeV/c)2, the longitudinal and ...
