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
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
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
Progress in nanoscience and nanotechnology depends not only on examining the surfaces of things but on seeing deep inside biological organisms and material structures to identify what they're made of — and what electronic, magnetic, optical, and chemical processes may be in play
The Solar and Heliospheric Observatory (SOHO) spacecraft is expected to discover its 1,000th comet this summer. The SOHO spacecraft is a joint effort between NASA and the European Space Agency. It has accounted for approximately one-half of all comet discoveries…
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…
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods. Dauphas' method, which he reports in the June 29 issue of the journal Nature, can now be used to tackle other mysteries of the cosmos that have remained unsolved for decades
Quantum computers that store information in so-called quantum bits (or qubits) will be confronted with a fundamental limitation. This is the claim made by Dutch theoretical physicists from the Foundation for Fundamental Research on Matter (FOM) and Leiden University in an article…
Whether mapping genes, probing elemental particles or monitoring global warming, more and more scientists rely on massive data vaults located at universities and institutions around the world
Energy Department Seeks Proposals to Use Scientific Computing Resources at Lawrence Berkeley, Oak Ridge National LaboratoriesJune 30, 2005 8:00 pm | News | Comments
Secretary of Energy Samuel W. Bodman announced that DOE’s Office of Science is seeking proposals to support computational science projects to enable high-impact advances through the use of some of the world’s most powerful supercomputers…
MINITAB features extensive graphical enhancements. advances expanded and simplified graph creation and editing, enhanced appearance of graphs, plus many new options to increase graph flexibility.
The statistical and design of experiments platforms included in JMP provide analysis capabilities to professionals who design and develop products, refine production processes or improve quality through Six Sigma initiatives.
ChemDraw chemical drawing software draws chemically aware structures for use in database queries, publication-quality graphics, modeling and other programs that require an electronic description of molecules and reactions.
ACD/ChemSketch software enables users to draw molecules, reactions and schematic diagrams, calculate physical properties, generate accurate IUPAC names for chemical structures, and design reports and presentations.
CAChe modeling software uses the MOPAC PM5 method for heats of formation that offers fast geometry optimizations, reaction modeling, quantum chemistry calculations, and additional transition metals and all main group elements in one MOPAC method.
