Concrete surface profile affects coating and lining adhesion. ICRI CSP Chips provide a visual, qualitative comparison, while ASTM D8271 describes direct quantitative measurement with a digital depth micrometer.

AI development in Vietnam is gradually shifting from simply using existing tools and models toward building self-reliant capabilities suited to the country's data, infrastructure, and domestic needs. Advancing further at the national level requires more than developing a new AI model. It also involves data, computing capacity, human resources, hardware, and the ability to independently verify technology.

Inspecting rooftop solar panels with a thermal imaging camera requires combining thermal images with visual inspection and electrical data before deciding on any corrective action. Hot spots may be associated with photovoltaic cells, bypass diodes, junction boxes, connectors, or wiring. However, shading, dirt, reflections, and irradiance conditions can also produce similar thermal patterns.

The proliferation of non-linear loads such as variable frequency drives, rectifiers, induction furnaces, and LED lighting systems is making harmonic pollution a major headache for industrial plants.

A practical overview of pull-off adhesion testing for coatings on rigid substrates, with guidance on dolly selection, test interpretation, and PosiTest AT applications.
