Pavement Surface Types and Distress Assessment Indicators
Pavement or road surfaces can be categorized into four general classes, i.e., asphalt, concrete, gravel, and brick and block. Pavement condition is assessed by measuring several pavement characteristics such as roughness, surface skid resistance, pavement strength, deflection, and visual surface distresses.

Capa Vehicle
A capacitor vehicle or capa vehicle is a traction vehicle that uses supercapacitors (also called ultracapacitors) to store electricity. (As of 2010), the best ultracapacitors can only store about 5% of the energy that lithium-ion rechargeable batteries can, limiting them to a couple of miles per charge. This makes them ineffective as a general energy storage medium for passenger vehicles. But ultracapacitors can charge much faster than batteries, so in vehicles such as buses that have to stop frequently at known points where charging facilities can be provided, energy storage based exclusively on ultracapacitors becomes viable

Aero L-159 Alca
The Aero L-159 ALCA[nb 1] is a subsonic light combat aircraft and advanced trainer developed in the single-seat L-159A and two-seat L-159B versions respectively, produced in the Czech Republic by Aero Vodochody. In 2003, the Czech Air Force fleet of 72 L-159A aircraft was reduced to 24 due to budget constraints. After several years of storage, the government has re-sold most of the redundant aircraft to both military and civilian operators, namely the Iraqi Air Force and Draken International. The L-159 has seen active combat use by the Iraqi Air Force against ISIS. In Draken's service, the L-159 (colloquially known as "Honey Badger") has been employed as an aggressor aircraft. Since 2007, six L-159A aircraft have been rebuilt into T1 trainer derivatives. In 2017, Aero Vodochody unveiled a newly built L-159T1 for the Iraqi Air Force while the Czech Air Force is set to acquire L-159T2 two-seaters.

Deep-Sea Smart Composites
To solve the global shortage of land and offshore resources, the development of deep-sea resources has become a popular topic. Deep-sea composites are widely used materials in abyssal resources extraction, and corresponding marine exploration vehicles and monitoring devices for deep-sea engineering. In the process of deep-sea resources extraction by DUVs and marine engineering, cracks and fractures or other types of damage can occur due to the fatigue and aging of materials in harsh abyssal environments. With the expansion of cracks and fractures, the composite material splits could lead to the failure of composite structures. Traditional damage detection methods are limited by outdated equipment, low intelligence and poor timeliness, making it difficult to directly detect defects. To avoid irreversible disasters caused by fatigue and aging, and to reduce manpower and financial costs required for periodic inspection, it is necessary to adopt deep-sea smart composites to meet the existing needs.
