چکیده
Abstract Laminates made of metal—glass fiber-reinforced polymers—metal layers require material parameters for each constitutive model the constituents. First, although parameter identification metallic materials has been frequently discussed, stepwise in terms uncertainties previously determined is investigated by concept error propagation. Second, calibration a orthotropy describing large deformation behavior glass kernel layer challenging process, especially against background reliable determination parameters. The main problem related to lack available experiments. This issue embedded local identifiability. Thus, article provides experiments determine both steel as well polymers. Particularly latter issue, $$\mu $$ ? -CT data chosen provide representative volume element, where all modes can be investigated. In this sense, locally unique and manner studied. A linear propagation uncertainty resulting whole set homogenized material. entire process discussed thoroughly, validation examples such bending deep drawing metal forming processes, are provided estimate prediction accuracy. respect, found applied finite element simulations layered metal–composite–metal processes used simulations. contribution, we restrict ourselves at room temperature.

CREDIBILISTIC PARAMETER ESTIMATION AND ITS APPLICATION IN FUZZY PORTFOLIO SELECTION
In this paper, a maximum likelihood estimation and a minimum entropy estimation for the expected value and variance of normal fuzzy variable are discussed within the framework of credibility theory. As an application, a credibilistic portfolio selection model is proposed, which is an improvement over the traditional models as it only needs the predicted values on the security returns instead of...

there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
15 صفحه اولLensed CMB simulation and parameter estimation
Modelling of the weak lensing of the CMB will be crucial to obtain correct cosmological parameter constraints from forthcoming precision CMB anisotropy observations. The lensing affects the power spectrum as well as inducing non-Gaussianities. We discuss the simulation of full sky CMB maps in the weak lensing approximation and describe a fast numerical code. The series expansion in the deflecti...
