biological modeling and evolution based synthesis of Metamorphic mechanisms
Journal of Mechanical Design, 2008Co-Authors: Liping Zhang, Delun Wang, Jian S DaiAbstract:A methodology for synthesis and configuration design of Metamorphic mechanisms is developed in this paper based on biological modeling and genetic evolution with biological building blocks. The goal is to conceive an appropriate source-Metamorphic-mechanism configuration when the multiple phases of kinematic functions are given. The key enabler is the way of developing genetic evolution in modeling and design by capturing the Metamorphic configuration characteristics. With the unique characteristic of achieving multiple working-phase functions in a mechanism, the Metamorphic mechanism possesses two Features: one, the ametabolic Feature referring to the specified working phases that can be accomplished by a number of traditional mechanisms; two, the Metamorphic Feature occurring in transition between different working phases, resulting in change of topology of the mechanism. Based on this transition between phases, the concept of mechanism evolution is for the first time introduced in this paper based on biological building blocks in the form of Metamorphic cells and associated intrinsic elements as the Metamorphic gene. This leads to development of cell evolution and genetic aggregation with mechanism decomposition and evolutionary operation based on mapping from the source-Metamorphic mechanism to multiphase working configurations. Examples are given to demonstrate the concept and principles.

Evolution Based Synthesis of Metamorphic Mechanisms
Volume 8: 31st Mechanisms and Robotics Conference Parts A and B, 2007Co-Authors: Liping Zhang, Delun Wang, Jian S DaiAbstract:A new methodology for configuration design of Metamorphic mechanisms is developed based on genetic evolutionary operation with biological building blocks. The goal is to conceive the appropriate source-Metamorphic-mechanism configuration given the multiple phases of kinematic functions in motion specifications. The key enabler of configuration synthesis is the method of capturing the Metamorphic configuration characteristics and the genetic evolutionary criteria and of developing genetic evolution in modeling and design. With the unique characteristics of achieving multiple working-phase functions, the Metamorphic mechanisms possess two Features: one, the ametabolic Feature referring to the specified sub-working phases that can be accomplished by traditional mechanisms; two, the Metamorphic Feature occurring transition between different working phases resulting change of topology of the mechanism. Based on this transition between phases, the concept of mechanism evolution is for the first time introduced in this paper based on biological building blocks in the form of Metamorphic cells and associated inner elements as the Metamorphic gene. This leads to development of cell evolution and genetic aggregation forms with mechanism decomposition and evolution formulation based on mapping from the source-Metamorphic-mechanism to multi-phases working configurations. Examples are given to demonstrate the concept and principles.Copyright © 2007 by ASME

Oscillatory zoned chrome lawsonite in the Tavsanli Zone, northwest Turkey
Mineralogical Magazine, 1999Co-Authors: Sarah C. Sherlock, Aral I. OkayAbstract:Blueschist-facies metabasite rocks from the Tavs∞ anl| Zone of northwest Turkey have been found to contain an abundance of lawsonite displaying oscillatory zoning. Lawsonite normally adheres to the ideal composition of CaAl2[Si2O7](OH)2.H2O. In two samples from the Tavs∞ anl| Zone, Al 3+ -Cr 3+ substitution has occurred. The Cr 3+ was probably present in the protolith as magmatic chromite, became incorporated into lawsonite during subduction, and is a Metamorphic Feature resulting from quantities of Cr in the protolith and local fluid conditions.

Islamic Philosophy and Occidental Phenomenology in Dialogue - Islamic Philosophy and Occidental Phenomenology in Dialogue
2014Co-Authors: Anna-teresa Tymieniecka, Nazif Muhtaroglu, Detlev QuinternAbstract:The deconstructive work which marked the XX century represented a benefit for thought. However Deconstructionism, which according to Derrida disseminates meaning and does not seek to remove the foundation of concepts, but only to exhibit the modalities of their development and functioning, is not concerned with satisfying the undying philosophical desire to “save the phenomena,” a desire early expressed by Plato, taken up by Leibniz and then by Hegel in his Phenomenology of the Spirit, and found again in the Husserlian search for a mathesis universalis and still today felt in the pressing problems related to communication. In effect what is difficult is not the deconstructing but rather the re-building! Even Nietzsche, who had outlined the immanent transcendence as the new form of the anthropological function of transcendence, failed to achieve any effective reconstruction of the horizon of meaning where the new phenomena of the post-metaphysics era could find adequate position. Something analogous had happened to the Husserlian phenomenological thought, despite it had enhanced the Nietzschean legacy, identifying in the Erlebnis (=living experience) itself the new resource of transcendence, which allowed to draw upon the logos constituting the world. But it is only with the phenomenology of life that the specific Metamorphic Feature of the logos, thus grasped, becomes evident. In human creative acts, particularly highlighted by A.-T. Tymieniecka, in fact, the «inward givenness of the life progress common to all living beings as such» is manifested, and there appears also the logos, which sustains it: a monistic but Metamorphic logos that proceeds from the spontaneous capacity of self-individualization of life and therefore upholds and comprises the autopoietic reproduction of pre-human constructivism as much as the creative-production-of-being of the ontopoiesis of the human level of life (cf.: A.-T. Tymieniecka, Impetus and Equipoise in the Life-Strategies of Reason, 2000, pp. 4-5). The discovery of this logoic versatility intrinsic to the flow of life leads us toward a new path of theoretic research, directed to grasp «the fullness of the Logos in the key of Life»: we can embark adventurously upon this path, renewing the illuministic-Kantian striving for “sapere aude!” (cf.: A.-T. Tymieniecka, The case of God in the new Enlightenment, 2009, pp. xxi-xxix)
