Unpiloted systems continue transforming civil and structural engineering by improving efficiency, accuracy, and safety while empowering civil and structural engineers to control costs. Unmanned aerial vehicles (UAVs), or drones, have captured much of the conversation. However, they are just one part of the equation. The construction industry is constantly looking for solutions

I've always been interested in how things work. I originally thought I'd study Applied Physics but after some reflection, engineering made more sense. It offered practical application, a clearer path into industry and broader career options. I studied a wide range of disciplines before specialising in mechanical engineering, which eventually

The classic sales funnel is outdated for Gen Z, as their shopping journey is now non-linear. It involves platforms like TikTok, Instagram and YouTube, focusing on viral videos, user-generated content and influencer recommendations rather than traditional ads. Landing pages have been replaced by in-app storefronts that turn moments of inspiration into

The study addresses the ethical implications of traffic decision-making in the context of autonomous vehicles. Researchers have validated a new technique that helps driverless cars to make “moral” decisions. The method tests how people judge the morality of driving decisions by sharing a variety of traffic scenarios with test subjects, and

For roughly three decades, the JPEG has been the World Wide Web’s primary image format. But it wasn’t the one the Web started with. In fact, the first mainstream graphical browser, NCSA Mosaic, didn’t initially support inline JPEG files—just inline GIFs, along with a couple of other formats forgotten to history.
