New thermal wave aspects on burn evaluation of skin subjected to instantaneous heating
Comparative studies on the well-known Pennes' equation and the newly developed thermal wave model of bioheat transfer (TWMBT) were performed to investigate the wave like behaviors of bioheat transfer occurred in thermal injury of biological bodies. The one-dimensional TWMBT in a finite medium was solved using separation of variables and the analytical solution showed distinctive wave behaviors of ...Show More
Characteristics of microsecond-pulse surface flashover on epoxy resin surfaces in SF6
Surface flashover on insulating materials is likely to occur in composite apparatuses in overvoltage situations. In order to investigate the surface characteristics of epoxy resin (EP) materials, before and after flashover, microsecond pulses were applied to simulate transient overvoltage situations in a power system. Within the SF6 filled experimental chamber, pulse voltages with a frequency of 5...Show More

A. Patriciu;K. Yoshida;J.J. Struijk;T.P. DeMonte;M.L.G. Joy;H. Stodkilde-Jorgensen
The origin of electrical burns under gel-type surface electrodes is a controversial topic that is not well understood. To investigate the phenomenon, we have developed an excised porcine skin-gel model, and used low-frequency current density imaging (LFCDI) to determine the current density (CD) distribution through the skin before and after burns were induced by application of electrical current (...Show More
Contact Burn Injuries: Experimental Assessments of Short Duration Contact Exposures
2021 IEEE International Symposium on Product Compliance Engineering (ISPCE)
Year: 2021 | Conference Paper |
The quantification of contact burn injury risk is an important part of many product development cycles and hazard assessments for industrial processes. Two well-known standards relied upon for performing these assessments are primarily based on experiments conducted in the 1940s. Partially due to the manner in which these experiments were conducted, the standards implicitly make the assumption tha...Show More

Burn wounds resulting from thermal insult to the skin are typically classified according to varying depth and therefore require differential levels of medical intervention. In this paper, two methods are proposed for assessing burn injury. The two methods compared are photometric stereo (PS) and spectral analysis. Firstly, PS represents a robust topography recovery algorithm that is implemented to...Show More
