Unexpected findings in a mouse study in which the safety of FD&C Red No. 40 (Red 40) was examined led to additional experimentation and to new statistical analyses and models. The possibility of acceleration of tumors raised questions about an operational definition of acceleration and of appropriate statistical methods for assessing acceleration. especially in the face of data dredging. The ev...

In order to enhance the display result of the LED display image, an improved algorithm of LED display image based on composed correction is proposed. Firstly, the correction principle and the development status of the current correction technologies of the LED display image is introduced, and the two main correction technologies are analyzed. Secondly, the theory of composed correction is propo...

Article history: Received 17 December 2014 Received in revised form 1 December 2015 Accepted 3 December 2015 Available online 19 December 2015 The data for the lightflux degradation and chromaticity shift of LED lamps exhibits a considerable amount of scatter due to intrinsic and extrinsic factors. In this study, some degradation models, such as the gamma process model, were reviewed in terms o...

Computerand web-based testing procedures are increasingly popular for the assessment of cognitive abilities and knowledge. This paper identified color red as a critical context factor that may influence the results. Two studies showed that color red may harm the performance in webbased tests of general knowledge. In Study 1 (N=131) a red (vs. green) progress bar impeded the performance in a kno...

We deal with the imaging spectrometer based on the Offner scheme. We define the optical transfer function of the imaging spectrometer based on the Offner scheme. We define the spectrum reconstruction error for red LED.

In this paper, we would like to introduce a second generation of headlight glare simulator to be used with a driving simulator that significantly improves spatial and brightness accuracy of previously developed prototype headlight glare simulator (Fullerton & Peli, 2009). The system combined a programmable off–the-shelf LED display board and a beamsplitter so that the LED lights, representing h...

The objective of this study is to investigate the effects of irradiation from light-emitting diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitted from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total flavonoids and several ...
