The minimum amount that can be detected and quantitatively analyzed by Fourier infrared spectrometer depends on the signal-to-noise ratio of measured gas spectrum. In order to use transform absorption spectroscopy measure CO<sub>2</sub>, CO, CH<sub>4</sub>, N<sub>2</sub>O other greenhouse gases, instrument detection limit mixed are studied. We propose a metho...

There are increasing applications that require precise calibration of cameras to perform accurate measurements on objects located within images, and an automatic algorithm would reduce this time consuming calibration procedure. The method proposed in this article uses a pattern similar to that of a chess board, which is found automatically in each image, when no information regarding the number...

BACKGROUND Research has shown that ethnic minority groups are less likely to participate in colorectal cancer (CRC) screening than the majority population and hence less likely to be diagnosed at an early stage when treatment is potentially more successful. OBJECTIVE To explore knowledge, attitudes and beliefs regarding CRC and CRC screening among ethnic minority groups in the Netherlands. ...
