First-principles design of nanomachines.
Learning from nature's amazing molecular machines, globular proteins, we present a framework for the predictive design of nanomachines. We show that the crucial ingredients for a chain molecule to behave as a machine are its inherent anisotropy and the coupling between the local Frenet coordinate reference frames of nearby monomers. We demonstrate that, even in the absence of heterogeneity, pro...
متن کاملFirst Principles Design of Ductile Refractory Alloys
The purpose of this work is to predict elastic and thermodynamic properties of Cr-based alloys based on first-principles calculations and to demonstrate an appropriate computational approach to develop new materials for high-temperature applications in energy systems. In this study, we choose Poisson’s ratio as screening parameter for identifying ductilizing additives to the refractory alloys. ...
متن کاملCreative Mechanism Design Based on First Principles
Knowledge-based design systems and creativity are opposing concepts: the formal models used in a computer system seem to define a closed design space, while the nature of creativity is to extend the space of designs. The opposition can be resolved by introducing a clear distinction between two spaces of design solutions: those that can be represented and analyzed using first principles knowledg...
متن کاملFirst things first: design principles for worthwhile educational videogames
Three design principles are advanced for multi-user educational videogames. First, they should support situative embodiment in academic knowledge, where personally meaningful activities and coherent narratives foster collective engagement. Second, they should offer multiple levels and forms of meaningful assessment and the opportunity to succeed, fail, and try again. Third, they should provide ...
متن کاملCONSIDERATION OF DESIGN FOR PRODUCTION PRINCIPLES IN SHIP HULL DESIGN
In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...
