High-speed rail is a frequently discussed topic, but one that has yet to become a reality in the U.S. A number of states and regions in the U.S. including Texas, California, the Pacific Northwest and Minnesota, to name a few, have planned projects to bring high-speed rail to fruition.
If a senior engineer left an organization suddenly, how many hours would it take for the engineering team to take over his projects, confident that they understand not only the designs, but why those designs are the way they are? The typical answer is “far too many”. Widespread use of CAE and data management tools have made this task much easier than before, but these tools do little to record the thinking behind the results.
Highlighting the impact of malicious software, Target suffered the largest retail hack in U.S. history during the Christmas shopping season of 2013. To help combat this worsening trend, Virginia Tech computer scientists have used causal relations to determine whether or not network activities have justifiable and legitimate causes to occur. The work effectively isolates infected computer hosts and detects in advance stealthy malware.
Computer scientists at the Univ. of California, San Diego have developed a tool that allows hardware designers and system builders to test security—a first for the field. There is a big push to create the so-called Internet of Things, where all devices are connected and communicate with one another. As a result, embedded systems—small computer systems built around microcontrollers—are becoming more common.

Two new "cyberlearning" platforms allow non-artists to create illustrations rivaling the work of expert designers. The platforms sidestep a key creative barrier by eliminating the need for drawing skills in developing new designs. The platforms represent an important step toward replacing or augmenting the use of paper to create designs.
Self-driving cars are motoring along: Google’s cars can navigate freeways comfortably, albeit with a driver ready to take control. But city driving has been a far greater challenge for the cars' computers. In a blog entry posted April 28, the project’s leader said test cars now can handle thousands of urban situations that would have stumped them a year or two ago.
A team of computer scientists, mathematicians and geophysicists in Germany have optimized the SeisSol earthquake simulation software at Leibniz Supercomputing Center to push its performance beyond the one petaflop/sec mark, which equates to one quadrillion floating point operations per second. SeisSol is used to investigate rupture processes and seismic waves.
In today’s fast-paced markets, engineers are continuously challenged to deliver products that meet market demand, improve operational efficiency and exceed customer expectations. Multiphysics simulation is an essential component of the product design workflow for creating innovative designs, especially when building prototypes becomes impractical or when taking actual measurements is not possible.

Researchers are working on a new algorithm that could make re-identification much easier for computers by identifying the major orientations in 3-D scenes. The same algorithm could also simplify the problem of scene understanding, one of the central challenges in computer vision research.
Long before next-generation sequencing technology appeared, clinicians have been taking family histories by jotting down pedigrees: hand-drawn diagrams recording how diseases may recur across generations. Now healthcare providers can create those diagrams digitally on an iPad screen with a few finger taps, during a face-to-face encounter with an individual and his or her family.
Microsoft has released an iPad version of its popular Office software suite, a breakthrough heralding a new era under a CEO who promises to focus more on the devices that people are using instead of trying to protect the company's lucrative Windows franchise. Thursday's unveiling of the much-anticipated iPad apps for Microsoft's software bundle comes nearly four years after Apple Inc. released the tablet computer.
Industrial plants must function effectively. Remedying production downtimes and breakdowns is an expensive and time consuming business. That is why companies collect data to evaluate how their facilities are doing. At the Hannover Messe Digital Factory, held April 7-11, researchers in Germany will show how operators can analyze these huge amounts of data and use it as an early warning system when problems threaten.
A smartphone app for recovering alcoholics that includes a panic button and sounds an alert when they get too close to taverns helped keep some on the wagon, researchers who developed the tool found. The sober app studied joins a host of others that serve as electronic shoulder angels, featuring a variety of options for trying to prevent alcoholics and drug addicts from relapsing.
Geneticists at the Univ. of California, Davis have decoded the genome sequence for the loblolly pine. The accomplishment is a milestone for genetics because this pine’s genome is massive. Bloated with repetitive sequences, it is seven times larger than the human genome and easily big enough to overwhelm standard genome assembly methods.
A new app developed by researchers the U.K. accurately measures color-based, or colorimetric, tests for use in home, clinical or remote settings, and enables the transmission of medical data from patients directly to health professionals. Called Colorimetrix, the app helps transform any smartphone into a portable medical diagnostic device.
Researchers are working to enable smartphones and other mobile devices to understand and immediately identify objects in a camera's field of view, overlaying lines of text that describe items in the environment. The innovation could find applications in "augmented reality" technologies like Google Glass, facial recognition systems and robotic cars that drive themselves.
Small wind turbines tend to be located in areas where wind conditions are more unfavorable and control systems of current wind turbines cannot adapt. To address this problem, researchers in Spain have developed an adaptive algorithm that can contribute toward making these miniature turbines more efficient.
A computer-aided design tool has been used by researchers at Virginia Tech and the Massachusetts Institute of Technology to create genetic languages to guide the design of biological systems.
