When the Radio Corporation of America was founded in 1919, one of its missions was to become the world’s leading radio communications company. Among RCA’s first steps was to build a center that would transmit international signals and telegraphic messages. In 1921 the company opened Radio Central, in Rocky Point on New York’s Long Island. […]
When wireless researchers or telecom companies talk about future sixth-generation (6G) networks, they’re talking mostly about their best guesses and wish lists. There are as yet no widely agreed upon technical standards outlining 6G’s frequencies, signal modulations, and waveforms. And yet the economic and political forces that will define 6G are already in play. And […]

Airbus has signed a trilateral agreement with Thales and Diehl Aerospace for the joint development of the flight control computers of CityAirbus NextGen. The central flight control system of CityAirbus NextGen, the electric vertical take-off and landing vehicle (eVTOL) being developed by Airbus, will combine extraordinary computing power with lightweight design and highest safety standards. […]
The trees were not coming back. In the years following the 2000 Walker Ranch Fire, Tom Veblen, a forest ecologist at the nearby University of Colorado, Boulder, saw that grass and shrubs were regrowing in the charred foothills, but he had to search to find the rare baby version of the tall ponderosa pines that […]
The way people talk about our overheating planet has been getting pretty spicy. Bland, neutral-sounding phrases like global warming are out; evocative words like crisis and emergency are in. Some activists have argued that more urgent language will jolt people into realizing that climate change is already here, prompting a speedier effort to cut greenhouse […]
Power firm is one step closer to enabling the green transition of energy systems Through the research project KogniGrid, Kongsberg Digital has investigated how digital twins can be used to ensure optimal operation of power grids. As a result, Kongsberg Digital recently launched a digital twin for power grids, called Kognitwin Grid. Power operator BKK […]
Learning Objectives Examine limits and targets in a multivariable controller. Look for constraint control and optimization in multivariable control. Understand that active limits and targets should not contain MV limits. One of the chief lessons of the multivariable process control (MPC) era is multivariable control is not a specialization, but rather a central aspect […]
New variants to the COVID-19 virus have challenged the capacity of existing testing methods to deliver fast and consistently accurate test results, as PCR tests must be sent to labs and can take days to be returned. Furthermore, rapid antigen alternatives struggle to match up to the gold standard. But to effectively slow the rate […]
It was one of the prettiest sights I have ever seen: our homemade rocket floating down from the sky, slowed by a white-and-orange parachute that I had worked on during many nights at the dining room table. The 6.7-meter-tall Nexø II rocket was powered by a bipropellant engine designed and constructed by the Copenhagen Suborbitals […]
