In the economic and political science literature on constitutional choice and constitutional design, David Hume is almost invariably associated with a master principle of design that is congenial to rationalactor approaches. I shall call this the knavery principle. As Hume put it, "in contriving any system of government, and fixing the several checks and controuls of the constitution, every man...

The emerging discipline of Service Science Management and Engineering (SSME) apart from developing theories strives to build and evaluate IT artifacts of utility for the service economy. Especially due to the interdisciplinary character of this new discipline and the imprint of rather behavioral science oriented disciplines, for some problem areas only few innovative artifacts have been scienti...

This paper focuses on the application of structuration theory, seeking to explicate analytical considerations by which key structurational constructs may be operationalized so as to guide a detailed empirical analysis. In so doing, the paper offers a methodological contribution in respect of the conduct of structurational-based IS research. Owing to its high level of abstraction, structuration ...

First order reasoning about hyperintegers can prove things about sets of integers. In the author’s paper Nonstandard Arithmetic and Reverse Mathematics, Bulletin of Symbolic Logic 12 (2006), it was shown that each of the “big five” theories in reverse mathematics, including the base theory RCA0, has a natural nonstandard counterpart. But the counterpart RCA0 of RCA0 has a defect: it does not im...

In recent years, impedance measurement method by piezoelectric (PZT) wafer activesensor (PWAS) has been widely adopted for non-destructive evaluation (NDE). In this method, theelectrical impedance of a bonded PWAS is used to detect a structural defect. The electro-mechanicalcoupling of PZT materials constructs the original principle of this method. Accordingly, the electricalimpedance of PWAS c...

The principle of Line Scan Thermography (LST) was used to develop a self-propelled infrared thermographic nondestructive testing device for the inspection large, relatively flat composite aerospace parts, such as aircraft wings. design unit allowed suppression noise from reflected radiation. new equipment, using LST method, provided defect detectability similar that achieved with classic, stati...

In this paper, free vibration analysis of a polymer-based nano-composite beam reinforced by boron-nitride nanotubes and subjected on elastic foundation, is studied. Smooth and defect-free nanotubes with uniform and directly- orientated in matrix are intended. Also, nanotubes’ distribution in the thickness direction of beam is regarded as a uniform distribution of the three different targeted on...

This paper addresses the problem of quality inspection of regular textured surfaces as, e.g., encountered in industrial woven fabrics. The motivation for developing a novel approach is to utilize the template matching principle for defect detection in a way that does not need any particular statistical, structural or spectral features to be calculated during the checking phase. It is shown that...

in this article economic loss means those losses occurring independently of physical damage to things or to a person's body or health. there are two main positions about reparability of these losses: in some countries like french, belgium, spain, italy and luxembourg as a principle rule economic loss is recoverable and there is no difference between economic loss and other losses. but in s...

Abstract Let K/k be an extension of number fields. We describe theoretical results and computational methods for calculating the obstruction to Hasse norm principle defect weak approximation one torus \[R_{K/k}^1{\mathbb{G}_m}\] . apply our techniques give explicit computable formulae when normal closure has symmetric or alternating Galois group.
