The research presented in this paper reports an analysis of daylight in three offices with different exposures and characteristics located in Naples (Italy). The goal was to fully investigate daylight characteristics, also considering the circadian impact of daylight entering these offices, with the hope to develop guidelines to better assess daylight quality in built environments. One of the m...

In this paper, the performance of chromatic adaptation transforms based on stable color ratios is investigated. It was found that for three different sets of reflectance data, their performance was not statistically different from CMCCAT2000, when applying the chromatic adaptation transforms to Lam’s corresponding color data set and using a perceptual error metric of CIE ∆E94. The sensors with ...

What does it take to qualify as a “problem for the twenty-first century?” Obviously, the topic must be of fundamental importance, it must be difficult to solve as manifested by the number of excellent people who have tried—but failed, and non-experts should be able to appreciate the basic issues. The particular problem described here, which involves finding certain geometric configurations that...

This PDF receipt will only be used as the basis for generating Europe PubMed Central (Europe PMC) documents. Europe PMC documents will be made available for review after conversion (approx. 2-3 weeks time). Any corrections that need to be made will be done at that time. No materials will be released to Europe PMC without the approval of an author. Only the Europe PMC documents will appear on Eu...

Although early goal-directed therapy (EGDT) has been a landmark in guiding the approach to patients with sepsis in the ED, few institutions seem willing and able to adopt it for all eligible patients. 1 The complexity and invasiveness of the protocol are the most frequently cited barriers. In particular, it has been underlined that many clinicians would not feel comfortable with inserting a cen...

in this article naser al-din shah’s accounts of travels to europe (safar-nameh) have bee examined and criticised in a discourse analysis approach. by using this approach, attention has been paid to linguistic factors, co-text and context of the situation (social, cultural, political and historical), and institutional position, as well as the writer's attitude which has been effective in informi...

Color appearance models provide a powerful tool for achieving a viewing condition independent color representation. However, current color appearance models such as CIECAM97s and CAM97s2 are more complex than previous CIE device independent color spaces, such as CIELAB and CIELUV. Therefore it is important to understand how to correctly measure and set the input parameters. This paper provides ...
