Trajectory Specification for High-Capacity Air Traffic Control

Automating separation monitoring and guidance would relieve human controllers of the primary responsibility for safe separation. The doubling or tripling of airspace capacity that will be needed over the next several decades will require that tactical separation guidance be automated for appropriately equipped aircraft in high-density airspace. Four-dimensional (4D) trajectory assignment (three-dimensional position as a function of time) will facilitate such automation. A standard trajectory specification format based on XML (Extensible Markup Language) is proposed for that purpose.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Optical Inspection System Finds Defects in Ultra-High-Speed Manufacturing

Researchers at the Fraunhofer Institute for Physical Measurement Techniques IPM in Germany have developed an optical inspection system called WIRE-AOI that can detect defects in strip products such as pipes, rails, and wires in real time. The system detects micro-defects that zoom past it at 10 meters per second, and are no thicker than a human hair. Workers then see the processed defects depicted graphically on a monitor, and can remove the corresponding pieces.

NASA Radar Demonstrates Ability to Predict Sinkholes

New analyses of NASA airborne radar data collected in 2012 reveal that radar detected indications of a huge sinkhole before it collapsed and forced evacuations in Louisiana that year. The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they happen, decreasing danger to people and property.

NASA Model Provides 3-D View of L.A. Earthquake

On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1.Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have developed a model of the earthquake, based on the distribution of aftershocks and other seismic information from the U.S. Geological Survey.A new image based on the model shows what the earthquake may look like through the eyes of an interferometric synthetic aperture radar, such as NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). JPL scientists plan to acquire UAVSAR data from the region of the March 28 quake, possibly as soon as this week, and process the data to validate and improve the results of their model. The UAVSAR flights serve as a baseline for pre-earthquake activity. As earthquakes occur during the course of this project, the team is measuring the deformation at the time of the earthquakes to determine the distribution of slip on the faults, and then monitoring longer-term motions after the earthquakes to learn more about fault zone properties.

Mini Science Lab Detects Multiple Bio Agents

It can cost hundreds of dollars and days to scan biological materials for important biomarkers that signal diseases such as diabetes or cancer using industry standard equipment. Researchers face enormous time constraints and financial hurdles from having to run these analyses on a regular basis. A Northeastern University professor has developed a single instrument that can do multiple scans at a fraction of the time and cost. That's because it uses considerably less material and ultra-sensitive detection methods to do the same thing. ScanDrop is a portable instrument no bigger than a shoebox that has the capacity to detect a variety of biological specimen. For that reason it will benefit a wide range of users beyond the medical community, including environmental monitoring and basic scientific research. The instrument acts as a miniature science lab, of sorts. It contains a tiny chip, made of polymer or glass, connected to equally tiny tubes. An extremely small-volume liquid sample — whether it's water or a biological fluid such as serum — flows in one of those tubes, through the lab-on-a-chip device, and out the other side. While inside, the sample is exposed to a slug of microscopic beads functionalized to react with the lab test's search parameters. The beads fluoresce when the specific marker or cell in question has been detected; from there, an analysis by ScanDrop can provide the concentration levels of that marker or cell. Because the volumes being tested with ScanDrop are so small, the testing time dwindles to just minutes. This means you could get near-real time measures of a changing sample — be it bacteria levels in a flowing body of water or dynamic insulin levels in the bloodstream of a person with diabetes.

R&S® SMB100A, NRP, FSW-K6, ZVL Radar Educational Videos

Welcome to our short video tutorials on how to test radars using Rohde & Schwarz test equipment. Access to most information about radar tests is pretty restricted, as many radar applications are military or secretive industrial research. To show some basic radar tests we have created radar demo tools, which functions at a frequency of 2.45 GHz, which is in the unlicensed 2.4 GHz Industrial, Scientific and Medical (ISM) band. So tests can be performed in unshielded rooms. The frequencies are also used by radar operating in the ITU "S"-band from 2.3 to 2.5 GHz for air traffic control, weather and marine radar.
