--- Software: The Digital Analytics programs have all been written in one version or the other of Borland's Pascal, as I find this to be the quickest and best general purpose language for PC's. Borland Delphi Pascal provides a well-known, powerful, and heavy-duty RAD (Rapid Application Development) environment for Microsoft Windows, but I have standardized on an older version of it. As I have explained in discussing DMSolver, Free Pascal is compatible with Borland Pascal and lets me provide at zero cost a compiler to users without having to worry about users encountering the many version changes (always incompatible with each other) and complexities of Delphi. (There are also complexities and version changes with the Free Pascal, but I can always distribute a free copy.) I also work in Microsoft Visual Basic (similar to Delphi) if the customer or application requires it, but I do not recommend Basic for larger projects. I can work in Borland's C++ Builder, a package which resembles Delphi but with C++ instead of Pascal as the language, but again I find Delphi or Lazarus/FreePascal is easiest for PC programming. (Lazarus is the gui IDE for Free Pascal.) In Feb. 1990, mechanical and aerospace engineer Peter R. Payne adopted EDTECH for his technical graphing needs. This led immediately to a long-term consulting relationship, active primarily from 1990 through 1997, with his firm, Payne Associates, Inc., and later Payne Dynafoils, Inc. of Severna Park, Maryland. The relationship unfortunately changed after Peter's death in late 1997, when company goals changed, and the company no longer exists since 2007. Almost all this consulting was done remotely with transfer of information by modem between Texas and Maryland, even before the internet became popular. During 1990...1997 I assisted Peter in his development of a set of interrelated analytical programs, BOAT3D, originally written primarily in Microsoft Visual Basic for DOS, and assisted him with various analyses and the preparation of an externally funded report on relating ride comfort to the nature of vehicle vibrations. Peter is the inventor of the Dynafoil(tm), a new concept in hydrofoil boats for high-speed travel in rough sea conditions.
In conventional hydrofoil boats the supporting wings are rigidly fixed to the hull, but in the Dynafoil, the main wing is mounted on a sprung and damped pair of arms which allow the severe oscillatory wave forces on it to be absorbed. Unfortunately, the Dynafoil project is no longer active. Peter's heirs graciously allowed me to take over the BOAT3D project in 2001. |
