The behavioral immune system (BIS) includes perceptual mechanisms for detecting cues of contamination.Former studies have indicated that moisture has a disgusting property.Therefore, moisture could be a target for detecting contamination cues by the BIS.We conducted two experiments to examine the psychophysical basis of moisture perception and clar
Many cost overruns in the world of construction are attributable to either unforeseen events or foreseen events for which uncertainty was not appropriately accommodated.It is argued that a significant improvement to project management performance may result from greater attention to the process of analyzing project risks.The objective of this paper
This paper presents a robust hybrid improved dolphin echolocation and ant colony optimization algorithm (IDEACO) for optimizing the truss structures with discrete sizing variables.The dolphin echolocation (DE) is inspired by the navigation and hunting behavior of dolphins.An improved version of dolphin echolocation (IDE), as the main engine, is pro
Planar and vertical epicycle frequencies and local angular velocity are related to the derivatives up to the second order of the local potential and can be used to test the shape of the potential from stellar disc samples.These samples show a Acoustic Guitar Pickups more complex velocity distribution than halo stars and should provide a more realis
To meet the demand of power head for high power deep hole Gift Set directional equipment, the double motor power head was developed by combining theory with field test.The key technologies of double motor power head, such as chuck, box and brake device were studied, and the industrial test Baby Soothers was carried out in Sihe Mine of Jincheng Anth
