Thank you for visiting this website.

This website's central purpose is to present some Results of my many years of study, research, investigation, and development in the fields of Mathematics, Science, and Engineering.

Some of these results involve the following works:

1) Complex System Simulator Development work:

Nolta Simulated Systems Software (NSSyssoft) is selling a new and novel PC Computer-Based Advanced Digital Communication System Modeler (AdvDCSM) software system tool product: AdvDSCM DCSS (Digital Communication System Simulator) T1 for use;

AdvDCSMT1DCSS (T1 version 1. and 2.) is a breakthrough tool for prototyping very intricate Convolutional or Block Coded Channel Signaling Communication (Comm) Systems or UnCoded Channel Signaling Comm Systems. Also, T1 version 2 is a powerful tool for prototyping very intricate Turbo Coded or Low-Density Parity-Check (LDPC) Coded Channel Signaling Comm Systems. It will allow the study of the application of Channel Codes in these systems to achieve Reliable Communication (Performance Optimization) of transmitted information through an impaired channel or multichannel.

Fundamental Idea: DISCIPLINED "Scientific Power"

T1 = T REX (King) in Modeling!

Did you see the movie or read the book Jurassic Park by Michael Critchton?: About Dinosaurs (Tyrannosaurus Rex, etc.) & Ian Malcolm's Chaos or something important like "Scientific Power" & Discipline.

Disciplined "Scientific Power": you earn the knowledge; you master and respect the power of the information.

Jurassic Park analogy (Lesson) is relevant here: the reasons why a competent scientist/engineer respects the works & discipline of others.

The system tool T1 possesses "Scientific Power" that can be used to generate information and to develop insight (understanding) for you about information-theoretic systems.

Search engines (Google, Bing, Yahoo, etc.) can lead you to this website to acquire extremely valuable information such as discussed in the 'Tutorial on Reliable Modeling and Simulation of Communication Systems' treatise/webpage and its Figure 1 or shown in this website's figures of Bit Error Rate (BER) Plots for DMT, Actual Coherency, Intersymbol Interference (ISI), Non-Square MQAM Signaling, Turbo Coded Signaling, and Low-Density Parity-Check (LDPC) Coded Signaling examples.

You can acquire a few facts from this website and not buy T1; and, thus, pass up a great opportunity to be an "Unique Explorer" in the World of "Virtual Digital Communication Systems."

The Model of today's "Internet Age" World is that "Information wants to be free."

But this model is a fallacy!!! Information and knowledge does in fact have a cost to it: overt or covert.

If you don't believe this then you don't understand Communication Theory (C.E. Shannon's 1948 work) and the modern Information Theory (Russian A.N. Kolmogoroff).

Buy T1 and become a "Unique Explorer" in the World of "Virtual Digital Communication Systems."

2) Scattering, Diffraction, and Propagation of Waves Investigation work:

My Investigation into one of the most important problems in science and mathematics: the study and development of accurate analytical and numerical formulations of the Physics of Diffraction, Scattering, and Propagation of Waves as applied to Complex 4-D (Space and Time) physical structures/systems. This endeavor belongs to the field of Computational Mathematical Physics and Engineering.

One of the fundamental and key problems of wave theory is the analytical description of the diffraction by edged obstacles. Exact formulations for interesting complex 4-D physical structures do not exist today. The joint application of the solved "canonical problems", the high-frequency theory of diffraction, and the principle of locality has been and is used today. Key to this approach is that the resulting diffracted/scattered fields/waves can be added together at any given location. Depending on the structure of the 4-D object, this approach is not valid. And, these asymptotic methods and their corresponding results can not be accurately verified since the true results can not be obtained analytically.

As a result, this problem is one of the most important problems in science and mathematics for obvious reasons.

As an example, in Communication Systems, this physics is used to describe the phenomenon of Fading in Mobile Digital Communications. Fading is a serious impairment of Reliable Communications.

Other extremely important applications involve devices of Invisibility (stealth) or Detection involving Radar Systems; SuperLens that can operate below the diffraction limit; and Energy (low and high) detectors, converters, and resonators.

Results of this extremely important Computational Science and Engineering investigation will be present at the appropriate times. Of course, you can contact me beforehand through the below listed ways.
