Sharpness is an important image quality attribute for projection displays. However, it has not been well studied for projection displays in the existing literature. In this paper, we conduct an experimental study of perceived sharpness on projection displays in a controlled environment. The basic idea is to simulate the optical blurring process with Gaussian filtering and apply them to selected natural...
This paper elucidates the importance of ion-yield enhancement through primary-ion bombardment in ultra-high surface sensitive Time-of-Flight Secondary Ion Mass Spectrometry (TOF-SIMS) measurements of Aluminum bond pad fluorine contamination. A good correlation is achieved, R2 of 0.97, with Auger Electron Spectroscopy (AES) that is commonly used for bond pad surface contamination quantification.
Neurotensin modulates dopamine and serotonin transmission in the brain. The study investigated whether genetic polymorphisms in the Neurotensin receptor 1 gene were associated with performance on processing speed and executive function. A total of 129 healthy Chinese-Han volunteers were recruited. Genotyping for three SNPs, including rs6090453, rs6011914, and rs2427422, was analyzed by using a PCR...
This research investigated the measured contrast of projection displays based on pictures taken by un-calibrated digital cameras under typical viewing conditions. A high-end radiometer was employed as a reference to the physical response of projection luminance. Checkerboard, gray scale and color complex test images with a range of the projector's brightness and contrast settings were projected. Two...
High quality information has an important impact on improving hospital efficiency and patient satisfaction and resolving patient disputes. In this paper, on the basis of the analysis of the research status of information quality and process performance, information quality is considered as an important contribution factor to improve process performance. Then, the research framework and main content...
The multi-fractal theory is applied for proposing the calculation formula of general fractal dimension according to the characteristic of rolling bearing vibration signal. The general dimension of measured non-stationary time-domain signal is calculated and analysed, the box dimension, the information dimension and the correlation dimension are obtained. Combined general dimension sequence value and...
