Background Robust quantitative analysis in positron emission tomography (PET) and in single-photon emission computed tomography (SPECT) typically requires the time-activity curve as an input function for the pharmacokinetic modeling of tracer uptake.

Ramo's theorem provides a convenient way of simulating the currents induced through the electrodes of a radiation detector by the movement of charge carriers. The concept of weighting potential or of weighting field is the key ingredient in the calcu

Using a model, developed earlier, of trap controlled conduction, which includes both the Meyer–Neldel rule and field assisted detrapping, we have simulated picosecond timescale drift mobility and drift velocity measurements in a-Si:H. This model is

Ultrasonic sensors have proven to provide valuable information on the thermoplastic foaming process in polymers. Measurement of the attenuation of the ultrasonic signal can be easily related to the nucleation process, i.e., the onset of bubble format

The extrusion foaming process involves several critical steps, in which the physical foaming agent plays a significant role: plasticization, solubility, nucleation and bubble growth. Although these aspects can be studied by different techniques, a no

We analyze the impact of trapped carrier relaxation on the determination of the microscopic electronic mobility of a-Si:H. The calculations show that, if there is relaxation, the mobility is substantially higher than that predicted by the standard mu

Neutron response functions for superheated droplet detectors have been analyzed from threshold up to 2 MeV incident energy, taking into account a gradual threshold function, in terms of temperature and incident energy. A method for obtaining fitted p

We have performed Monte Carlo (MC) calculations of the temperature (T) and field (F) dependence of the behavior of the multiple-trapping model assuming exponential band tails of localized states with two different models for field-dependent effects f
