Concrete floor slab flatness and levelness are parameters often specified in construction documents that contractors must meet to ensure a high quality of construction. However, the measurement of these parameters is cumbersome and time-consuming.

Multi-terminal DC (MTdc) systems based on high-voltage DC (HVDC) transmission technology is an upcoming concept. In such systems, either asymmetric monopole or bi-pole systems are generally employed. Such systems are not suitable for easy expansion.

Real-time tracking and monitoring of radioactive/nuclear materials during transportation is a critical need to ensure safety and security. Current technologies rely on simple tagging, using sensors attached to transport containers, but they have limitations.

Stability performance of interconnected power grids plays crucial roles on their secure operation to prevent cascading failure and blackout.

Free-standing, thin films were fabricated with a binder resulting in nearly an order of magnitude thickness decrease while increasing porosity and activation energy. These effects of such diminished significantly. Free-standing films could be fabricated with a binder.

This technology creates a light and metalless current collector for battery application. Cathodes coated on this new current collector demonstrated similar contact resistance, lower charge transfer resistance and similar or high rate performance.

Additively manufacturing of the windings with a conductor distributed in the cross-section according to the Hilbert curve provides many benefits as it allows for the reduction of the high-frequency losses due to the reduction of the effective winding conductor size.

Making existing buildings more airtight is critical in reducing the nation's energy consumption and carbon output. Most current methods of locating building leakage sites are disruptive to occupants and none of the methods can measure the flow of individual leakage sites.
