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...

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

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

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

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

Study Shows How Granular Materials Get Themselves Out of a Jam

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

Glass flows just like liquids do, but at such a super-sluggish pace that for all practical purposes it takes on the appearance of a solid at room temperature. Yet after years of experiments, scientists still have failed to determine if atoms arrange themselves differently in glass than in liquids…
