    • Automatic Qualitative Analysis of Ordinary Differential Equations Using Piecewise Linear Approximations 

      Sacks, Elisha (1988-03-01)
      This paper explores automating the qualitative analysis of physical systems. It describes a program, called PLR, that takes parameterized ordinary differential equations as input and produces a qualitative description of ...

    • Automatic Qualitative Modeling of Dynamic Physical Systems 

      Amsterdam, Jonathan (1993-01-01)
      This report describes MM, a computer program that can model a variety of mechanical and fluid systems. Given a system's structure and qualitative behavior, MM searches for models using an energy-based modeling framework. ...

    • Hypothesizing Device Mechanisms: Opening Up the Black Box 

      Doyle, Richard James (1988-06-01)
      I describe an approach to forming hypotheses about hidden mechanism configurations within devices given external observations and a vocabulary of primitive mechanisms. An implemented causal modelling system called ...

    • The Performance of a Mechanical Design 'Compiler' 

      Ward, Allen C.; Seering, Warren (1989-01-01)
      A mechanical design "compiler" has been developed which, given an appropriate schematic, specifications, and utility function for a mechanical design, returns catalog numbers for an optimal implementation. The compiler ...

    • Qualitative Process Theory 

      Forbus, Kenneth D. (1984-07-01)
      Objects move, collide, flow, bend, heat up, cool down, stretch, compress and boil. These and other things that cause changes in objects over time are intuitively characterized as processes. To understand common sense ...
