Research Computing Lab Short Course: LaTeX

“LaTeX Basics”

 Aubry Verret, Research Computing Support Specialist

Monday, February 8, 2010, from 3:30 p.m. to 5:00 p.m.

In the Brown Science and Engineering Library Electronic Classroom

This class is a hands on introduction for those who have no prior experience with LaTeX but are interested in using it to write academic/scientific papers. It will contain an overview of capabilities and features as well as basic commands. By the end of the class you will be able to create a document that includes sections, figures, a bibliography and mathematics.

Anyone interested in attending a session is asked to sign-up by submitting a ticket at the following url:   http://www2.lib.virginia.edu/brown/rescomp/help/index.html.

Squeezing Out More Power

Piezoelectric Material Harvests Record Amount Of Energy.

Technology Review (1/29) reports, “Researchers at Princeton University have created” a piezoelectric material that “can harness 80 percent of the energy applied when it is flexed–four times more than existing flexible piezoelectric materials.” The researchers used PZT, “the most efficient piezoelectric material known, but its crystalline structure means that it must be grown at high temperatures, which normally melt a flexible substrate. The Princeton researchers, led by mechanical engineering professor Michael McAlpine, got around this by making PZT at high temperatures and then transferring thin ribbons of the material onto silicone.” The researchers are particularly focused on biomedical applications.

Nuclear Fusion Milestone

Scientists Reach Milestone In Nuclear Fusion Experiment.

According to the National Nuclear Security Administration (NNSA), AFP (1/29) reports, “US scientists have produced a laser shot with an unprecedented energy level that could be a key step towards nuclear fusion.” In a statement, the NNSA said that “researchers for the first time delivered a megajoule of energy to a target by focusing 192 laser beams at the same time at a temperature of 111 million Celsius (200 million Fahrenheit).” NNSA administrator Thomas D’Agostino said, “Breaking the megajoule barrier brings us one step closer to fusion ignition,” adding, “This milestone is an example of how our nation’s investment in nuclear security is producing benefits in other areas, from advances in energy technology to a better understanding of the universe.”

In a report that only refers to the NNSA’s funding of the project, the San Francisco Chronicle (1/29, Perlman) reports that scientists at the Lawrence Livermore National Laboratory’s National Ignition Facility said that their work “marked the most important advance yet in more than 10 years of work at the $3.5 billion facility.” In the coming months, “the team will start a new round of experiments seeking finally to achieve what they call ‘ignition’ — a true thermonuclear reaction inside the laboratory’s tiny targets.” L. Jeffrey Atherton, one of the lead physicists on the project, said, “We’re confident of our ability to start seeking ignition this summer.” Atherton added, “And we’re optimistic that at some point soon we’ll achieve it.”

Federal Highway Administration Documents

U.S. Department of Transportation: Federal Highway Administration:  Geotechnical Engineering [pdf]

http://www.fhwa.dot.gov/engineering/geotech/pubs/century/index.cfm

 This important site contains a report which summarizes Federal Highway Administration (FHWA) geotechnical research and development activities over the past 25 years. The report’s author is Al DiMillio, and it is divided into seven chapters, some concluding remarks, and four appendices. The chapters cover material related to road construction and detailed maintenance and strengthening projects. Each chapter provides a background essay on the subject, along with information about each project and technical material on the ways in which each project was successfully completed. Visitors can navigate the work by subsections as well, and they will also want to look over the appendices, which give detailed histories of previous works on this subject. [KMG]

NOTE:  The parent site also contains a wealth of additional information and documents related to highways and geotechnical engineering.
