Coming Soon - Additive Manufacturing Initiatives at Sandia National Laboratories

Additive manufacturing (AM), commonly referred to as 3D printing, is a hot topic these days. Sandia National Laboratories has been pioneering development and commercialization of the technology for over 30 years now.

Are FAA drone rules too restrictive?

This week's Question: This month, the Federal Aviation Administration proposed long-awaited rules on the commercial use of small drones, requiring operators to be certified, fly only during daylight, and keep their aircraft in sight. The ruling, for now, prevents drones from being used for a range of possible other commercial uses, including crop inspection and package delivery. What do you think? Are FAA drone rules too restrictive?

Restricting Sugar-Sweetened Beverages From SNAP Purchases Not Likely To Lower Consumption

To reduce obesity and improve health outcomes, some policymakers and nutrition advocates have argued that Supplemental Nutrition Assistance Program (SNAP) benefits should not be allowed to be used for purchasing sugar-sweetened beverages. ERS research suggests that such a restriction is not likely to have much of an impact on SNAP participants' consumption of these beverages.

Measuring Access to Food in Tanzania: A Food Basket Approach

Household access to food over time in Tanzania is measured by comparing the cost of representative food baskets to household income. Consumption patterns show considerable diversity across the country. Combining food basket cost data and income data suggests that households in the bottom two income quintiles have significant difficulties with access to food.

Recession Had Greater Impact on Visits to Sit-Down Restaurants Than Fast Food Places

American Time Use Survey (ATUS) diaries from 2003-11 reveal that visits to sit-down restaurants declined during and after the 2007-09 recession, while fast food visits were little changed.

How Do Households Respond to Rising Food Prices in Developing Countries? (1)

ERS analyzed Indian household consumption data to estimate the effects of rising food prices on food consumption and household welfare. Researchers found that because rice prices rose faster than wheat prices, households whose diets were dominated by rice suffered more than households who ate more wheat.

Many U.S. School Districts Serve Local Foods

USDA’s Farm to School Census, covering school years 2011-12 and 2012-13, found 36 percent of responding school districts served locally produced food in school meals and an additional 9 percent planned to serve local foods in the future.

Multivariate Time Series Search Capability to Identify Complex Patterns in Large Datasets

Ames Research Center, Moffett Field, California
There exist many datasets that can be viewed as multivariate time series, such as the daily high temperature at a locality, sensor recordings in diagnostic systems and scientific data, and music and video recordings. These time series reside in large repositories, and there is often a need to search for particular time series exhibiting certain types of behaviors. Many current approaches to time series search are too slow on large repositories, or constrain the range of possible queries.

NGDCS Linux Application for Imaging-Spectrometer Data Acquisition and Display

NASA’s Jet Propulsion Laboratory, Pasadena, California
A simple method of controlling recording and display of imaging spectrometer data in (airborne) flight was needed. Existing commercial packages were overly complicated, and sometimes difficult to operate in a bouncing plane. The software also was required to keep up with the imaging data rate, while still running on commodity hardware and a desktop operating system. Finally, the software needed to be as robust as possible — repeating a flight because of lost data is sometimes impossible, and always expensive.

Kepler Community Data Analysis Tools

Ames Research Center, Moffett Field, California
A series of scripts stitch together existing open-source Python modules for the purpose of displaying, cleaning, and measuring photometric properties within public Kepler data. The intent of these tools is to provide convenience to the Kepler science community, and to increase cost efficiency for the project. With 500+ users in the community, an open-source development provides the best resource for sharing tools, while minimizing cost and duplicated effort.
