A close correlation between Stiles's increment threshold (pi-mechanism) approach and color discrimination at threshold was found: a sharp transition from detection of two lights via two pi-mechanisms (pi 1 and pi 4) to detection via only one pi-mechanism (pi 1) was paralleled by a sharp decline from excellent discrimination between those two lights (even with the rods bleached) to no discrimina...

In today's world, food security is an important issue. Food shortages push prices up, impacting upon the health and well-being of hundreds of millions of rural poor across the globe. One way to increase food security is to decrease the amount of yield lost to pests. This encyclopedia provides a comprehensive overview of the fight against pests, covering chemical pesticides, biocontrol agents an...

Th is article examines the history of the veil and its changing social meanings in Iran. Embedded in the meaning of the veil is the erotic meaning of female hair. Th e symbiotic relations of the “cover” (the veil) and the “covered” (female hair) are central to this history. Iranian political regimes have assigned to the veil meanings corresponding to their own ideologies. Th rough imposed unvei...

We study the Rendezvous problem for 2 autonomous mobile robots in asynchronous settings with persistent memory called light. It is well known that Rendezvous is impossible in a basic model when robots have no lights, even if the system is semi-synchronous. On the other hand, Rendezvous is possible if robots have lights of various types with a constant number of colors [9, 22]. If robots can obs...

Abstract—In this paper, we propose the variational approach to solve single image defogging problem. In the inference process of the atmospheric veil, we defined new functional for atmospheric veil that satisfy edge-preserving regularization property. By using the fundamental lemma of calculus of variations, we derive the EulerLagrange equation foratmospheric veil that can find the maxima of a ...

Lights and siren are frequently used by Emergency Medical Service (EMS) groups to reduce response times and increase a patient’s chance for survival. However, the use of lights and siren in EMS patient transport has been associated with occasional inappropriate use, higher crash rates involving the ambulance, and a potential “wake effect” increasing crash rates in ambient traffic. This study ex...
