4+ hour, 54+ min ago   (632+ words) Beneath many of the world’s cities and agricultural regions lies a hidden network of long-distance water conveyance tunnels, structures that move drinking water, irrigation supplies and hydropower flows across tens or even hundreds of kilometres. These tunnels are among the…...

2+ day, 22+ hour ago   (736+ words) Standing up the narrow prototype had been genuinely fast. Portable agent policy, skills, and repo bootstrap had already made that part easy. Safe retirement was not. The experiment had tested one narrow claim: a working agent could turn captured learnings…...

2+ day, 22+ hour ago   (414+ words) To evaluate freeze–thaw damage and asymmetric deterioration in shallow-buried bias tunnel linings in cold regions, an explainable data-driven predictive framework was developed. Guided by the underlying frost heave mechanisms, an optimal support vector machine (SVM) surrogate model was trained…...

4+ day, 10+ hour ago   (421+ words) Keeping a pole balanced vertically on a single point is a classic control problem. Even the slightest disturbance will cause it to start falling, and once that happens, a control system has to react quickly enough to push it back…...

6+ day, 3+ hour ago   (258+ words) MIT researchers sent a remotely operated robot beneath 3.6 feet of Arctic ice and managed to transmit data through the frozen surface, a step toward...

5+ day, 13+ hour ago   (654+ words) Large deformation is one of the most critical hazards in tunnels excavated under complex geological conditions. It often causes significant economic losses and threatens construction safety. For layered soft rock tunnels subjected to high in situ stress, the deformation and…...

5+ day, 22+ hour ago   (23+ words) MIT researchers have demonstrated through-ice communication using magnetic fields, combining rugged sensors, robotics, and magneto-inductive electronics to collect data beneath Arctic sea ice....
