In the heart of Washington, D.C., contractors are working tirelessly to install heat pumps in townhouses as part of a larger effort to embrace greater home electrification. While not as glamourous as electric cars or as visible as solar panels, heat pumps play a crucial role in the shift towards more energy-efficient living spaces. This
Following an engine fire incident on a Cathay Pacific flight, Europe’s aviation safety agency has taken a proactive step in mandating inspections on a part of the fleet of Airbus A350 wide-body jets in operation. The engines on Cathay’s A350s are manufactured by Rolls-Royce, which has confirmed the initiation of “a one-time precautionary engine inspection
Emotion recognition is a crucial aspect of human interaction, providing valuable insights into a person’s mental state. Traditional emotion recognition systems have relied on static images, which limit their ability to capture the dynamic nature of emotions as they evolve over time. However, a new research study by Lanbo Xu from Northeastern University in Shenyang,
Fuel cells have emerged as a promising energy-conversion solution that generates electricity through electrochemical reactions without combustion, thereby reducing air pollution. These cells have the potential to power a wide range of technologies, from electric vehicles to portable chargers and industrial machines. However, many existing fuel cell designs rely on expensive materials and precious metal
The Volkswagen “dieselgate” scandal first came to light in 2015, when the German auto giant admitted to installing software to manipulate emissions levels in millions of vehicles across the globe. This revelation marked the beginning of one of Germany’s most significant post-war industrial scandals. Former CEO Martin Winterkorn played a key role in this scandal,
The concept of public transportation has been around for decades, providing a vital service for communities all over the world. However, with the rise of the gig economy and new technological advancements, it is time to rethink the traditional approach to public transit. Researchers at Concordia University have proposed a new system called On-Demand Transit
In the world of rideshare apps, the process of pairing drivers with riders efficiently is crucial. It’s not just about getting someone from point A to point B quickly, but also ensuring that the system maximizes happiness for all parties involved. This process, known as bipartite matching, is not just limited to rideshare apps. It’s
The recent blocking of a popular social media platform, referred to as X, in Brazil has sparked a heated debate among users and politicians regarding the legitimacy of such bans.
