State space modeling of differential-algebraic systems using singularly perturbed sliding manifolds
(Massachusetts Institute of Technology, 1999)
This thesis introduces a new approach for modeling and control of algebraically constrained dynamic systems. The formulation of dynamic systems in terms of differential equations ·and algebraic constraints provides a ...
Multi-connection vias for printed circuit boards
(Massachusetts Institute of Technology, 1999)
As the performance of digital electronic components improves, maintaining the integrity of high-frequency signals through circuit boards becomes increasingly challenging. The dimensions and material parameters of in-plane ...
Problems in interface fracture
(Massachusetts Institute of Technology, 1990)
A three-dimensional mathematical model of the human knee joint
(Massachusetts Institute of Technology, 1990)
Hydrostatic machine tool spindles
(Massachusetts Institute of Technology, 1996)
This work investigates the application of hydrostatic bearings, particularly those of the self-compensating type, to precision machine tool spindles. First, relations are developed that can be used to calculate the hydraulic ...
A model approach to precision motion control
(Massachusetts Institute of Technology, 1999)
Understanding estimation and its relation to engineering education
(Massachusetts Institute of Technology, 1999)
A wide variety of engineering activities benefit from the use of rough estimates of the type commonly referred to as back-of-the-envelope calculations. These include evaluating the feasibility of an idea, planning experiments, ...
Dynamic analysis and control system design for an advanced nuclear gas turbine power plant
(Massachusetts Institute of Technology, 1990)
Cyclic deformation of monocrystalline nickel aluminide and high temperature coatings
(Massachusetts Institute of Technology, 1990)
High green density metal parts by vibrational compaction of dry powder in three dimensional printing process
(Massachusetts Institute of Technology, 1996)
The material properties and dimensional accuracy of metal tooling produced by the Three Dimensional Printing process can be enhanced by increasing the green density of the 3D printed part. Green density is the ratio of ...
