14. Comparative study of thermal stability and crystallization kinetics between melt-spun and bulk Pd77.5Cu6Si16.5metallic glasses

Abstract

A comparative study on the thermal stability and kinetics of crystallization of both melt–spun and bulk Pd77.5Cu6Si16.5metallic glasses was performed. Rapidly quenched Pd77.5Cu6Si16.5ribbon and as–cast bulk metallic glass (BMG) sample were produced by melt spinning and copper mold casting, respectively. Phase identification and transformation were studied by X–ray diffraction (XRD), transmission electronic microscopy (TEM), and differential scanning calorimeter (DSC) measurements. In non-isothermal conditions, the activation energies were calculated by Moynihan and Kissinger methods, respectively. The nucleation and growth during the crystallization were investigated in the frame work of the local activation energy and the local Avrami exponent. The local activation energy was calculated by Kissinger–Akahira–Sunose, Flynn–Wall–Ozawa and Vyazovkin methods. The local Avrami exponent was calculated. The experimental results indicated that the characteristic temperatures depend on the heating rate. The obtained activation energies indicated that the Pd77.5Cu6Si16.5amorphous alloys exhibit excellent thermal stability. The thermal stability of Pd77.5Cu6Si16.5BMG is better than that of ribbon. The local activation energy Eaincreases to a maximum and then decreases. It is indicated by local Avrami exponent that the crystallization processes of both Pd77.5Cu6Si16.5amorphous ribbon and BMG are controlled by volume nucleation with three-dimensional growth with various nucleation rates. The crystallization process of Pd77.5Cu6Si16.5amorphous ribbon is close to that of BMG. The isothermal crystallization kinetics of Pd77.5Cu6Si16.5amorphous ribbon is investigated and compared with the results of non-isothermal crystallization kinetics.

15. Optimal strategic recognition of objects based on candidate discriminating graph with coordinated sensors

Abstract

Recognizing the objects using multiple sensors greatly relies on an appropriate sensing strategy that coordinates the sensors in a feasible and least expensive way to extract the information that is critical for recognition. An approach to this strategic recognition of objects based on the proposed candidate discriminating graph (CADIG) is presented. A CADIG represents the candidates of an unknown object and the complete discriminating relations between the candidates in terms of relevant discriminators (geometric features). Based on a CADIG, the strategic recognition is decomposed into two interacting procedures, the information acknowledgment procedure (IAP) and the sensory acquisition procedure (SAP). The IAP identifies the critical information for recognition as a set of discriminators from the CADIG and receives sensory examinations of these discriminators to eliminate invalid candidates from the CADIG. The SAP coordinates multiple sensors to examine the critical information identified in the IAP. Based on a proposed constraint-based dynamic model of senors, this coordination is formulated as a constraint satisfaction problem and solved by the backtracking algorithm. The unknown object is recognized through iterations of the IAP and SAP until there is only one candidate left in the CADIG. The IAP and SAP are further integrated to achieve the optimal strategic recognition of objects. The amount of computations needed in this CADIG-based recognition is substantially reduced by pruning redundant discriminators from the CADIG. Reliable and knowledge-based recognition of objects is obtained by applying the Dempster-Shafer theory of belief functions. Computer simulations were performed to verify the feasibility and to analyze the performance of the optimal strategic recognition of objects.
