I investigated a method for facial expression recognition for a human speaker by using thermal image processing and a speech recognition system. In this study, we improved our speech recognition system to save thermal images at the three timing positions of just before speaking, and just when speaking the phonemes of the first and last vowels. With this method, intentional facial expressions of...

This study is to propose new method, called by TDP (time dependenet parameter) anlaysis, of physiological signal processing for emoiton recognition. TDP consised of delay, activation, half recovery and full recovery. TDP was determined from running average and normalization of physiological signals for finding tonic and phasic reponse according to emotion at entire time range from stimulating e...

Post-deposition rapid thermal annealing ~RTA! was performed on multilayered films consisting of a Mn capping layer on top of CoCrPt/CrTi/NiAl. High coercivities were achieved even at low M rt values and coercivity values increased more than that would have been predicted by the decrease in magnetization values. This is most likely due to the significant decrease in intergranular exchange coupli...

The tunneling magnetoresistance and perpendicular magnetic anisotropy in CoFeB(1.1-1.2 nm)/ MgO/CoFeB(1.2-1.7 nm) junctions were found to be very sensitively dependent on annealing time. During annealing at a given temperature, decay of magnetoresistance occurs much earlier compared to junctions with in-plane magnetic anisotropy. Through a rapid thermal annealing study, the decrease of magnetor...

In this paper infrared (IR) measurements and dedicated signal processing algorithms were developed and applied for defect detection on green ceramic tiles. Tiles with defects having known dimension and position were realized and tested by acquiring either heating and cooling transients of the tile subjected to thermal pulse excitation. As rarely defects appear directly in the thermal map, post-...

We show that the thermal and electrical properties of single wall carbon nanotube ~CNT!-polymer composites are significantly enhanced by magnetic alignment during processing. The electrical transport properties of the composites are mainly governed by the hopping conduction with localization lengths comparable to bundle diameters. The bundling of nanotubes during the composite processing is an ...

Infrared image processing systems are used in the beginning only as visualization systems for observation of people and objects in the night or as night vision systems. Next in these systems are included the blocks and algorithms for thermal image processing and these systems became the base of the today’s infrared image processing systems. There are many areas of infrared image processing syst...

Most customers in electricity markets do not face prices that change frequently to reflect changes in wholesale costs, known as real-time pricing (RTP). We show that not only does time-invariant pricing in competitive markets lead to prices and investment that are not first best, it even fails to achieve the constrained second-best optimum. Increasing the share of customers on RTP is likely to ...
