Electrothermal behavior

The response is indicative of die electrothermal behavior of die bridgewire-explosive interface. Bridgewir.es which deviate from the characteristic heating curve have been dissected and examined to determine the cause of die abnormality. Deliberate faults have been fabricated into squibs. The relationship of the specific abnormality and the fault associated with.it have been demon strated (Ref 1, abstracted in Ref 3)... 

The paramagnetic spinel CdCr204, when surrounding a superconducting wire shows a kind of electrothermal behavior changes in current induce changes in temperature. A current in the wire has a magnetic field around it and the chromite... 

Ihe paper of Ref 2, abstracted in Ref 3> reports a technique that will yield insight into the quality of EBW devices in a nondestructive manner. By employing a self-balancing bridge it is possible Co ascertain die electrothermal and nonlinear behavior of the device. A sinusoidal current is passed thru the device which provides a signal in the form of a unique Lissajous Display (See Note, below). This display can be qualitatively evaluated and abnormal units can be readily detected... 

Zeeman Effect Background Correction Background correction with electrothermal atomizers can be done by means of the Zeeman effect. Here a magnetic field splits normally degenerate spectral lines into components with different polarization characteristics. Analyte and background absorption can be separated because of their different magnetic and polarization behaviors. 

Electrothermal atomic absorption represents a suitable instrumental technique for the analysis of elements in petroleum products [1-5]. The technique shows very low detection limits, similar to or even better than those found for other spectroscopic techniques, such as Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) [6] and ICP-Mass Spectrometry (ICP-MS) [7-12]. Some problems were evidenced in the use of ETAAS when elements like Ni [3] and Pb [13] are analyzed, due to the different behavior of organo-metallic species during the thermal treatment of standards and samples. 

To imderstand the operation of the battery and to be able to accurately forecast its characteristics and lifetime, it is essential to have comprehensive models available that describe its behavior. Considerable research efforts have been devoted to the design of electrical models or equivalent circuits for the battery in order to have a hill view of the occurring phenomena it is however necessary also to take into accoimt the thermal behavior through thermal and electrothermal modeling. 

In order to have a more accurate prediction of the thermal behavior of the battery cell in any environmental condition, the proposed thermal model should be extended to become an electrothermal model. This approach is needed for an accurate determination of the internal resistance and for the estimation of the state of charge (see Figure 11.13). Based on this approach, there will continuously be an interaction between the electrical and the thermal models.
