Modeling and optimization of precipitation hardening heat treatment factors of Al2024 alloy using a two-level full factorial design
In the current study, the sources of variation in the mean hardness value of heat treated aluminum 2024 samples were identified by using metallurgical study and design of experiment methodology (full factorial method). Hardness measurements and microstructural investigations of the samples were carried out using Brinell hardness test and optical microscopy, respectively. The effects of several ...
متن کاملOn-orbit prospective echocardiography on International Space Station crew.
OBJECTIVES A prospective trial of echocardiography was conducted on six crew members onboard the International Space Station. The main objective was to determine the efficacy of remotely guided tele-echocardiography, including just-in-time e-training methods and determine what is "space normal" echocardiographic data. METHODS Each crew member operator (n = 6) had 2-hour preflight training. Ba...
متن کاملCardiovascular regulation during long-duration spaceflights to the International Space Station.
Early evidence from long-duration flights indicates general cardiovascular deconditioning, including reduced arterial baroreflex gain. The current study investigated the spontaneous baroreflex and markers of cardiovascular control in six male astronauts living for 2-6 mo on the International Space Station. Measurements were made from the finger arterial pressure waves during spontaneous breathi...
متن کاملParticipatory Design; A New Approach to Regenerate the Public Space
The following study aims to present an innovative approach for Design. Participatory Design is the model of direct involvement of different social groups in the design from functional tools to environments, social institutions and businesses. Diverse collection of practices has been developed to support this direct involvement by Participatory Design. People are invited to participate during di...
متن کاملDesign space optimization using a numerical design continuation method
A generalized optimization problem in which design space is also a design to be found is de9ned and a numerical implementation method is proposed. In conventional optimization, only a portion of structural parameters is designated as design variables while the remaining set of other parameters related to the design space are often taken for granted. A design space is speci9ed by the number of d...
