Electromagnetic Interference (EMI) resulting from high rates of changes of voltage and current, impairing other devices’ performance and harming human being’s health, has become a major concern in designing direct current (DC-DC) converters for a long time due to the increasingly wide applications of various electrical and electronic devices in industry and daily life. Thus, the question of how...

Data pre-processing plays a vital role in data mining for ensuring good quality of data. In general data preprocessing tasks include imputation of missing values, identification of outliers, smoothening out of noisy data and correction of inconsistent data. In this paper, we present an efficient missing value imputation technique called DMI, which makes use of a decision tree and expectation ma...

Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...

Intraoperative neurophysiological monitoring (IONM) is utilized to minimize neurological morbidity during spine surgery. Transcranial motor evoked potentials (TcMEPs) are principal IONM signals in which the motor cortex of the subject is stimulated with electrical pulses and the evoked potentials are recorded from the muscles of interest. Currently available monitoring systems require the conne...

The emitter series resistances (Rs,emi) can be extracted from experimentally measured JV curves using the two-light intensity method (TLIM) but it can also be calculated from the emitter geometry using analytical formulas and finally also computed with arbitrary precision using finite element simulation (FES). On the one hand formulas and FES consider Rs,emi as distributed, on the other hand th...

This application report presents the background, details, and usage of the EMI Rejection Ratio (EMIRR) parameter.

BACKGROUND Little objective laboratory data are available describing the physiologic effects of stun guns or electromuscular incapacitation (EMI) devices, but increasing morbidity and even deaths are associated with their use. We hypothesized that exposure to EMI discharges in a model animal system would induce clinically significant acidosis and cardiac arrhythmia. METHODS Ten Yucatan mini-p...
