By both numerical simulation and experimental investigation, we found it possible to enlarge the grain size (∼3000 Å) of polycrystalline silicon (poly-Si) films by excimer laser annealing, using a new method to control the solidification process of molten Si - low-temperature (≦400°C) substrate heating during laser annealing. Poly-Si thin-film transistors (TFTs) fabricated by this new excimer laser annealing method showed a high field-effect mobility of 230 cm2/V·s, and good uniformity of field-effect mobility (±10%) within the effective laser irradiation area.
Skin temperature is an effective indicator for objectively evaluating human sensations, because it is controlled by sympathetic nerve activity which reflects the course of information processing in the brain. In this paper, we show a method to evaluate stress from skin temperature and an equipment which continuously measures skin temperature of an subject working in front of a computer terminal.An experiment is performed to investigate a relationship between stressfull task and the skin temperature. The experiment shows that there is a high correlation among stress, skin temperatures on nose and forehead. From this experiment, a regression equation is derived which computes the intensity of stress from skin temperatures on nose and forehead.A non-contact skin temperature measuring system is developed based on knowledge obtained in the experiment. The system comprised of an infrared camera, color camera, image processing unit and work station. The features are the abilities to track nose and forehead positions of an subject doing computer operation automatically and to evaluate the stress continuously.
It is shown that Pad6 approximants can be obtained directly from the Fredholm expansion for scattering phase shifts. The accuracies of various Pad6 and Fredholm approximants taken up to the third order in the strength of the interaction potential are assessed by evaluating the S-wave phase shifts for the elastic scattering of particles by square-well and exponential potentials. The second-order Pad6 and Fredholm approximants are found to be quite accurate and both superior to the second Born approximation, while taken t o third order they generally yield very accurate yalues for the phase shifts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
