40 years of massive city growth as seen from space

by Laura Domela

Cities across the globe have seen unprecedented growth in recent decades. While revisiting a city after a period of time can reveal some surprising changes, the true extent of the expansion of some urban centers can only be truly appreciated from above. Way above.

The Landsat satellite program is the longest continuous archive of images of Earth from space in existence. Run by the USGS and NASA since Landsat 1 launched on July 23, 1972, this record of the surface of our planet reveals invaluable insight for scientists and the public alike. A record like this is particularly useful for studying change and understanding the human impact on the landscape.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
