In practical system identification it is often desirable to simultaneously handle several objectives and constraints. In some cases, these objectives and constraints are often non-commensurable and the objective functions are explicitly/mathematically not available. In this paper, Interactive Evolutionary Computation (IEC) is used to effectively handle these identification problems. IEC is an o...

Usability and guessability are two conflicting criteria in assessing the suitability of an image to be used as password in the recognition based graphical authentication systems (RGBSs). We present the first work in this area that uses a new approach, which effectively integrates a series of techniques in order to rank images taking into account the values obtained for each of the dimensions of...

In this paper, a quantitative multicriteria futuristic fuzzy decision hierarchy (MFFDH)-based SWOT (strengths, weaknesses, opportunities and threats) analysis has been carried out to determine priorities among significant factors related to tourism’s internal and external environment. In MFFDH model, the fuzzy logic is combined with analytic hierarchy process (AHP) to overcome the uncertainty i...

Different methods have been proposed for merging multiple and potentially conflicting informations. Sum-based operators offer a natural method for merging commensurable prioritized belief bases. Their popularity is due to the fact that they satisfy the majority property and they adopt a non cautious attitude in deriving plausible conclusions. This paper analyses the sum-based merging operator w...

In [6], Kontsevich and Zorich conjecture that the fundamental groups of strata of the moduli space of abelian differentials are commensurable with various mapping class groups. In this paper we consider a similar question for strata of quadratic differentials, and in particular we construct a quotient group of the fundamental group for a certain family of strata. We do so by mapping a stratum i...

A modular grid is a pair of sequences ( f m ) $ (f_m _m$ and g n (g_n _n$ weakly holomorphic forms such that for almost all n, the coefficient q $q^n$ in $f_m$ negative $q^m$ $g_n$ . Zagier proved this duality weights 1/2 3/2 Kohnen plus space, grids have appeared Poincaré series, integral weight, many other situations. We give general proof canonical row-reduced bases spaces or half-integral w...

Existing educational practices focus on subject matter knowledge that is, through the act of teaching, brought into the heads of students. Materials, texts, or images qua aspects of the learning environment are treated as given in terms of fixed and unambiguous structures (ontologies). Drawing on examples from a large data base on learning physics through laboratory activities, I show that (a) ...

We provide a brief review of recent theoretical studies of optical spatial solitons in parity-time(PT-) symmetric mixed linear-nonlinear lattices. The existence and stability of optical spatial solitons forming in PT-symmetric lattices with spatially periodic modulation of the Kerr nonlinearity are briefly overviewed. The linear optical lattices are considered to be either regular lattices or s...

Microenvironmental mechanical properties of stem cell niches vary across tissues and developmental stages. Accumulating evidence suggests that matching substrate elasticity with in vivo tissue elasticity facilitates stem cell differentiation. However, it has not been established whether substrate elasticity can control the maturation stage of cells generated by stem cell differentiation. Here w...

A newmultiobjective particle swarm optimization (MOPSO) technique for environmental/economic dispatch (EED) problem is proposed in this paper. The proposed MOPSO technique evolves a multiobjective version of PSO by proposing redefinition of global best and local best individuals in multiobjective optimization domain. The proposedMOPSO technique has been implemented to solve the EED problemwith ...
