Introduction


Thermography is a non-contact, non-destructive test method that utilizes a thermal imager to detect, display and record thermal patterns and temperatures across the surface of an object. Infrared thermography may be applied to any situation where knowledge of thermal profiles and temperatures will provide meaningful data about a system, object or process.

Since infrared radiation is emitted by all objects based on their temperatures, according to the black body radiation law, thermography makes it possible to see one's en ....etc

ABSTRACT

Thermography is a non-contact, non-destructive test method that utilizes a thermal image to detect, display and record thermal patterns and temperatures across the surface of an object. Thermography is widely used in industry for predictive maintenance, quality assurance and forensic investigations of electrical, mechanical and structural systems. Other applications include, tank and concrete inspection, nondestructive testing, condition monitoring, night vision and medical and veterinary sciences.

Thermography is useful because: ....etc

Abstract Breadth-first and depth-first search are basic search strategies upon which many other search algorithms are built. In this paper, we describe an approach to integrating these two strategies in a single algorithm that combi ....etc

Infrared thermography has evolved into one of the most valuable diagnostic tools for Predictive Maintenance of electrical equipment from reliability and safety point of view.

By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur or where safety of man and machine are at stake. By utilizing thermography to inspect electrical systems and components under load, the faulty components can be identified and thus heavy loss of health and wealth is avoided.

Definition
Satellites have been used for years to provide communication network links. Historically, the use of satellites in the Internet can be divided into two generations. In the first generation, satellites were simply used to provide commodity links (e.g., T1) between countries. Internet Protocol (IP) routers were attached to the page link endpoints to use the links as single-hop alternatives to multiple terrestrial hops. Two characteristics marked these first-generation systems: they had limited bandwidth, and they had large latencies t ....etc
