Several approaches for optimization of fluorescence lifetime imaging microscopy (FLIM) system have been recently suggested. This paper discusses the influences of photons losses on the optimization of FLIM systems based time-correlated single photon counting (TCSPC) technique, considering the limitations associated with detecting the required amount of photons by the system. The fluorescence intensity (FI) and f Read More

The scientific and accurate prediction for state of bearing is the key to ensure its safe operation. A rotating bearing monitoring system was presented in U.S. Patent 7606673 and a bearing condition monitoring apparatus was presented in U.S. Patent 8229682, however, the system or apparatus lacks state prediction function of bearing. State prediction of bearing based on relevance vector regression algorithm with RB Read More

The THREAD Act (Transportation Recall Enhancement, Accountability and Documentation) mandated the use of a suitable tyre pressure monitoring system (TPMS) technology in all light motor vehicles under 5 tons. In the United States, as of 2008 and the European Union, as of November 1, 2012, all new passenger car models released must be equipped with a TPMS. This would alert drivers of under-inflation events. Many co Read More

Block matching motion estimation is a popular method in developing video coding applications. The use of fixed pattern prevents the motion estimation algorithms from locating the actual position of the global distortion minimum. Hence, to address the problem of local optima in motion estimation, it can be viewed as an optimization process to find the best matching block with reduced number of search points which is s Read More

Chemometrics, a relatively young area of analytical chemistry involves extracting meaningful information from experimental data by utilizing mathematical, statistical, and computational methods with the ultimate goal of evaluating and interpreting analytical data or signals. In this article, we provide a comparison of the performance of various chemometrics techniques using data obtained from the colored complexes for Read More

Mostly pure tone fault of loudspeakers in the world is detected by human hearing. Obviously the accuracy could not be guaranteed due to subjectivity and it is easy to cause auditory fatigue. Based on the characteristics of loudspeaker’s pure tone detection, we propose that the response signal of frequency sweep can be converted into two-dimension timefrequency image signal to enhance the characteristics of Read More
