Look Who’s Talking

Spectral learning algorithm for speech separation Bill Weaver, Ph.D. I do not know the first thing about teaching science to the blind. Even my earliest course in problem solving begins with Step 1: Read the Problem; Step 2: Draw a Picture of the Situation — both initial steps inextricably associated with sight. I've exhausted cases of dry-erase markers and meters of chalk creating elaborate diagrams on the board


The Legacy of Microsoft .NET: Delphi 2005 fully integrates .NET programming components

July 31, 2005 8:00 pm | by John R. Joyce, Ph.D. | Articles | Comments

Okay, the main focus of this column is not Microsoft .NET, but it does have a role to play, so please hang in there. I suppose the best place to start is with the question, What is Microsoft .NET? Unfortunately, that is a much more difficult question to answer than one might expect. The reason being that Microsoft’s marketing department has on occasion managed to apply the name


Catching Up with Chuck Johnson

June 30, 2005 8:00 pm | Articles | Comments

An early innovator shares his insights and vision for the future of mathematics Scientific Computing recently caught up with Charles "Chuck" W. Johnson, an early mathematics innovator, MIT alumni and Corporation Development Committee member, and founder of Visual Numerics (formerly IMSL). During our exchange, Chuck talked about his role in evolving mathematics and statistics into mainstream business analytics, as well as the profound changes the mathematics industry has seen over the past 50 years.


The Unscrambler: A Different Approach to Multivariate Data Analysis and Experimental Design

June 30, 2005 8:00 pm | by John A. Wass, Ph.D. | Articles | Comments

This is a program you may hate the first few hours and love forever after John A. Wass, Ph.D. Unscrambler is specifically directed to multivariate analysis and experimental design, with emphasis on problems in chemistry and industrial production. It is one of the more unusual packages that I have seen in terms of its logic and, in this regard, may be a welcome change


The Importance of Nothing... Identifying character errors through font substitution

June 30, 2005 8:00 pm | by John R. Joyce, Ph.D. | Articles | Comments

No! Calm down, this isn't going to be a nihilist diatribe, I have something much more concrete in mind — data validation, in fact. Hang in there, you'll see the connection soon. The bane of the laboratory is data entry errors. These can take many forms, sometimes they are simple transcription errors, sometimes it is a substitution error, where one character is mistaken


When Push Comes to Shove

June 30, 2005 8:00 pm | by Bill Weaver, Ph.D. | Articles | Comments

Quantum imaging with magnetic resonance force microscopy Bill Weaver, Ph.D. The amount of force required to press the keys of a computer keyboard is around 1 newton (N). That’s about the force provided by a pad of Post-it notes as it mistakenly rests on your spacebar, filling the buffer until your computer emits a barrage of clicks for help. On the high side of things, the world-record holder


Mathematics and Biology: Toxicogenomics as the New Frontier

June 30, 2005 8:00 pm | by John A. Wass, Ph.D. | Articles | Comments

The latest installment of my crusade to bring the biologists and mathematicians/statisticians together was given a small assist from a very interesting and scientifically "hot" area known as toxicogenomics. Recently, Morgan et. Al .[1] had published a paper entitled "Complementary Roles for Toxicologic Pathology and Mathematics in Toxicogenomics


My New Laptop Does Not Have Any RS232 Ports & #151 What Should I Do??

June 30, 2005 8:00 pm | by Thomas Lutz | Articles | Comments

Easy solutions for connecting to a USB port Thomas Lutz Although USB stands for “universal serial bus,” the USB interface does not work anything at all like a standard RS232 serial port. Like RS232 serial ports, the USB ports on a PC are designed for interfacing external devices. However, any piece of equipment that is designed to connect to a USB port must come with a Windows device driver that essentially informs


When Data Meets Math

June 30, 2005 8:00 pm | by Paul Goossens | Articles | Comments

A look at three emerging data reduction techniques that allow scientists to use data acquired from existing dynamic systems to rapidly generate mathematical models Paul Goossens Data and numbers drive engineering and science and, over the past decades, we have accumulated a vast range of software and hardware tools to efficiently gather and analyze immense datasets. But is data enough? Increasingly, industry is realizing that data supported by rich mathematical models


Leading with the Intellect

June 30, 2005 8:00 pm | by Randy C. Hice | Blogs | Comments

Remembering Digital’s Ken Olsen Randy C. Hice My boss, Doug, had witnessed another member of our unit make insulting comments to me during a unit meeting. He asked me into his office the next day to compliment my restraint. “I would have expected you to retaliate in the meeting, you really are maturing
