Components used for thermal protection have not previously been interrogated with the impedance method. In this study, structures are fabricated to represent typical thermal protections systems. The replicas are designed to simulate actual protection systems in use. Observations are made into the verification of the impedance method in effectively monitoring complex thermal protection systems f...

Condition monitoring of power transformers, which are key components electrical systems, is essential to identify incipient faults and avoid catastrophic failures. In this paper machine learning algorithms, i.e., nonlinear autoregressive neural networks support vector machines, proposed model the transformer thermal behavior for purpose monitoring. The models developed based on historical measu...

ABSTRACT. The effectiveness of structural health monitoring via ultrasonic methods is seriously compromised by changing environmental conditions such as temperature. Variations in temperature can be spuriously identified as damage owing to thermal expansion or contraction of the material as well as changing of the wave propagation speed. This problem becomes even more serious when temperature c...

Background: Lactoperoxidase (LPO) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. The aim of this study was to provide information on activity and thermal inactivation behavior of LPO in Iranian cow and buffalo milk and whey. Methods: Sixty cow and buffalo milk samples were collected. The LPO activity was measured using spe...

A novel fully integrated dynamic thermal management circuit for system-on-chip design is proposed. Instead of worst-case thermal management used in conventional systems, this design yields continual monitoring of thermal activity and reacts to specified conditions. With the above system, we are able to incorporate on-chip power/speed modulation and integrated multi-stage fan controllers, which ...

Vision is one of the most powerful forms of non-contact sensing for monitoring and control of manufactusang processes. However, processes involving an arc plasma or flame such as welding or thermal spraying pose particularly challenging problems to conventional vision sensing and processing techniques. The arc or plasma is not typically limited to a single spectral region and thus cannot be eas...

A popular retrofit option is to install an exterior insulation finish system to the walls of existing buildings. This study evaluates the thermal and moisture performance of such a system with a vented wall assembly. In addition to being a case study, this field monitoring was intended to verify computation methods of building envelope performance. The long term monitoring was designed to be no...
