Notes on Consulting

---by Dail Singleton, PhD

Summary of expertise:

  • PhD (University of Rochester) and BChE (University of Delaware) in chemical engineering with research in fluid flow with mixing and involving numerical computations modelling various dynamic systems.

  • Delphi Pascal (MS Windows), Basic, and FORTRAN programming (general purpose and including numerical algorithm design and development)

  • Statistical programming, regression analyses and teaching of statistics and other courses as adjunct faculty, University of Houston Clear Lake. Earlier work was as an analyst with an interdisciplinary engineering/business group at the University of Houston Central Campus studying energy, chemical and environmental economics.

  • Technical writing

  • Analyses using linear and nonlinear optimization techniques and related to the energy and chemical industries


Some Details --- Analysis:
  Consulting over the last thirty years has included a number of projects involving the analysis of pre-existing databases as regards issues such as correctness and completeness of data in a large corporate database, and evidence for or against racial, sexual, age, etc. discrimination in corporate or governmental databases. This work has been performed in collaboration with colleague Dr. R. R. Hill, a professor at the University of Houston at Clear Lake. In this work Dr. Hill provides his expertise in the areas of statistical theory and methodology, and I have provided implementation of statistical calculations on the computer using various commercial software or custom written routines. Microsoft Access databases were used on the last project and we have used Stata and SPSS statistical packages.

--- Software:
 Digital Analytics software is designed to speed the analysis of complex (or simple!) systems. As a consultant I am able to customize the software and develop special purpose applications for the user. For example, I have customized BOAT3D when the user's boat shape could not be matched by the standard version.

  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.


The Prototype Dynafoil(tm):

Prototype Dynafoil

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.
