There are two broad approaches to formal statistical inference taken as concerned with the development of methods for analysing noisy empirical data and in particular as the attaching of measures of uncertainty to conclusions. The object of this paper is to summarize what is involved. The issue is this. We have data represented collectively by y and taken to be the observed value of a vector ra...

This paper presents the issues necessary to solve in the designing process of multichannel optical communication systems topologies. The main design assumption is the acceptance of multichanneling in communication system realization. In particular, the basics of designing physical and logical topologies are shown. Also cost aspects of physical and logical topologies realization are shown.

We investigate the gauging of conformal algebras with relations between the generators. We treat the W 5/2 –algebra as a specific example. We show that the gauge-algebra is in general reducible with an infinite number of stages. We show how to construct the BV-extended action, and hence the classical BRST charge. An important conclusion is that this can always be done in terms of the generators...

The concept of symmetry is of central importance in modern physics. Plenty information can be extracted from the symmetry of a physical system. In field theory, the symmetry plays an essential role in defining some very basic concept like particle, charge, etc. Symmetry also put strong constraint on the properties of fields/particles, as well as their interactions and correlations. In quantum f...

Centering Theory is the best known conceptual framework for theorizing about local coherence and salience; however, its claims are articulated in terms of notions which are only partially specified, such as ‘previous utterance’, ‘realization’, or ‘ranking’, and can be viewed as PARAMETERS of the theory. A great deal of research has been concerned with providing more detailed specifications for ...

‎in this paper, using the idea of convexificators, we study boundedness and nonemptiness of lagrange multipliers satisfying the first order necessary conditions. we consider a class of nons- mooth fractional programming problems with equality, inequality constraints and an arbitrary set constraint. within this context, define generalized mangasarian-fromovitz constraint qualification and show t...

A solution methodology employing finite elements and a parameterized expectations algorithm is proposed for computing the equilibrium of a CIA model economy. The stochastic growth model considered introduces money via a CIA constraint, and takes consumption as the cash good and leisure and capital investment as credit goods. The ability of the methodology to approximate the solution of the mode...

Configuring consists in simulating the realization of a complex product from a catalog of component parts, using known relations between types, and picking values for object attributes. This highly combinatorial problem in the field of constraint programming has been addressed with a variety of approaches since the foundation system R1[9]. An inherent difficulty in solving configuration problem...

This paper considers a one-stage stochastic mathematical program with a complementarity constraint (SMPCC) where uncertainties appear in both the objective function and the complementarity constraint, and an optimal decision on both upper and lower level decision variables must be made before the realization of the uncertainties. A partially exactly penalized sample average approximation (SAA) ...
