In this article, we study the coding problem for real-valued Lévy processes X (original) under Lp[0, 1]-norm distortion for some fixed p ∈ [1,∞). Here we think of X being a D[0,∞)-valued process, where D[0,∞) denotes the space of càdlàg functions endowed with the Skorohod topology. We shall denote by ‖ · ‖ the standard Lp[0, 1]-norm. Let 0 < s ≤ ∞. The objective is now to find a càdlàg real-val...

real coded genetic algorithm, rcga, is the type of ga which operates on chromosomes with real valued parameters. different mutation and crossover operations are defined for rcga. one usable crossover for this kind of ga is to consider its chromosomes simply as bit strings and utilize the same operations as binary coded ga. in this paper, we attempt to show that this kind of crossover can not ha...

We study the one-sided limit order book corresponding to limit sell orders and model it as a measure-valued process. Limit orders arrive to the book according to a Poisson process and are placed on the book according to a distribution which varies depending on the current best price. Market orders to buy periodically arrive to the book according to a second, independent Poisson process and remo...

Purpose – The primary purpose of this study is to illustrate an analytical method to identify tangible and intangible customer values and to translate those values into brand identity differentiators and product specifications. Design/methodology/approach – The authors adapt a product development analysis tool, the Value Opportunity Analysis (VOA), to the design of a brand identity, illustratin...

In this paper we compare the expressive power of elementary representation formats for vague, incomplete or conflicting information. These include Boolean valuation pairs introduced by Lawry and Gonzalez-Rodriguez, orthopairs of sets of variables, Boolean possibility and necessity measures, three-valued valuations, supervaluations. We make explicit their connections with strong Kleene logic and...

We propose a set–valued framework for the well–posedness of birth– and–growth process. Our birth–and–growth model is rigorously defined as a suitable combination, involving Minkowski sum and Aumann integral, of two very general set–valued processes representing nucleation and growth respectively. The simplicity of the used geometrical approach leads us to avoid problems arising by an analytical...

We consider the tree-valued Fleming–Viot process, (Xt)t≥0, with mutation and selection as studied in Depperschmidt, Greven and Pfaffelhuber (2012). This process models the stochastic evolution of the genealogies and (allelic) types under resampling, mutation and selection in the population currently alive in the limit of infinitely large populations. Genealogies and types are described by (isom...

process management (pm) is a structured, systematic approach that is adopted by firms in order to analyze, improve and control their processes. this paper has been focused on identifying and testing the effective critical success factors (csfs) in the preparation and successful implementation of process management. according that in this study by reviewing the literature and studying various re...

We define and study a quantale-valued Wijsman structure on the hyperspace of all non-empty closed sets of a quantale-valued metric space. We show its admissibility and that the metrical coreflection coincides with the quantale-valued Hausdorff metric and that, for a metric space, the topological coreflection coincides with the classical Wijsman topology. We further define an index of compactnes...
