Interconnecting two adjacent areas of electricity production generates benefits in combined consumer surplus and welfare by allowing electricity to flow from the low cost area to the high cost area. It will lower prices in the high cost area, raise them in the low cost area and will thus have prices in the two areas converge. With unconstrained interconnection capacity, price convergence is, of course, complete and the two areas are merged into a single area. With constrained interconnection capacity, the challenge for transport system operators (TSOs) and market operators is using the available capacity in an optimal manner. This...

In this paper, we give precise mathematical form to the idea of a structure whose data and axioms are faithfully represented by a graphical calculus; some prominent examples are operads, polycategories, properads, and PROPs. Building on the established presentation of such structures as algebras for monads on presheaf categories, we describe a characteristic property of the associated monadsthe shapeliness of the titlewhich says that “any two operations of the same shape agree”. An important part of this work is the study of analytic functors between presheaf categories, which are a common generalisation of Joyal's analytic endofunctors on sets and of...

El cuidado y conservación de los ecosistemas forestales es un tema que, actualmente,
resulta de interés mundial, ya que se tratan de la solución a diferentes problemas
medioambientales, sociales y culturales. Hacer uso de prácticas de manejo de tierras
para asegurar la protección, conservación, restauración y aprovechamiento de los
recursos forestales producen alteraciones en las propiedades fisicoquímicas,
microbiológicas y bioquímicas del suelo, las cuales pueden llegar a afectar a las
funciones del mismo. En este trabajo se han estudiado las propiedades de dos parcelas,
una tratada y otra control, para poder comparar las propiedades de cada una y así
conocer como varían en un periodo corto de tiempo....

While classical image processing algorithms were designed for scalarvalued (binary or grayscale) images, new technologies have made it commonplace to work with vectorvalued ones. These technologies can involve new types of sensors, as in remote sensing, but also mathematical models leading to an increased cardinality at each pixel. This work analyzes the role of firstorder differentiation in vectorvalued images; specifically, we explore a novel operator to produce a 2D vector from a Jacobian matrix, in order to represent the variation in a vectorvalued image as a planar feature.

This work extends the notion of consistency in terms of stability for Families of Aggregation Operators (FAO), as defined in previous works. The notion of stability proposed in this work, not only extends the previous one, but it can be applied to a wider set of FAOs, particularly, to those that we name here as Family of Improper Aggregation Operators (FIAO), or improper FAOs. When the aggregated value cannot be considered as a new item from the input, the present definition of onsistency cannot be applied. This is usual in several areas, namely in the development of social, economic and...

This paper focuses on key issues related to aggregation tools within knowledge acquisition, and in particular for image processing. In particular, it is claimed the need of a number of simultaneous indices in order to evaluate the quality of a fuzzy classification (e.g., overlapping, covering and relevance), and that such a family of indices should allow learning, giving a hint on how such a classification can be improved. Our guess is that those indices can be obtained from certain families of wellknown aggregation tools.

In this paper we discuss about graph approach in image segmentation. In first place, some main image processing techniques are classified based upon the output these methods provide. Then, a fuzzy image segmentation definition is presented because in the literature review was found that it was not clearly defined. This definition of fuzzy image segmentation is then related to a hierarchical image segmentation procedure, so this concept is also formally defined in this work. As every output of an image processing algorithm has to be evaluated, then a method to evaluate a hierarchical segmentation output is proposed in order to...

Hesitant Fuzzy Sets are useful to represent the information given by several experts. However, this possibility usually require to deal with sets of values with different cardinality and the necessity to compare them, it is, not all experts evaluate all the elements in the universe. In this paper it is proposed a new nomenclature for Hesitant Fuzzy Sets called Hesitant Fuzzy Sets using Lists. It is proposed a new partial order relation between lists of membership degrees. This partial order relation allows to handle lists with different lengths. In addition, Hesitant Fuzzy Relations on Lists operations are defined and the...

The problem of missing data is common in realworld applications of supervised machine learning such as classification and regression. Such data often gives rise to the need for functions defined for varying dimension. Here we propose optimization methods for learning the weights of quasiarithmetic means in the context of data with missing values. We investigate some alternative approaches depending on the number of variables that have missing values and show results for several numerical experiments.

In this paper, the meaning of a vague concept α is assumed to be rendered through two (mutually exclusive) finite sets of prototypes and counterexamples. In the remaining set of situations the concept is assumed to be applied only partially. A logical model for this setting can be fit into the threevalued Łukasiewicz’s logic Ł3set up by considering, besides the usual notion of logical consequence = (based on the truth preservation), the logical consequence =≤based on the preservation of all truthdegrees as well. Moreover, we go one step further by considering a relaxed notion of consequence to some degree a...

The cognitive theory of conceptual blending models human creativity as a mental process that combines two mental spaces into a new mental space, called a blend. According to this theory, a blend is constructed by taking the commonalities among the input mental spaces into account, to form a socalled generic space, and by projecting their noncommon structure in a selective way to the novel blended space. In this paper, we apply this idea to blend input spaces modeled as complex EL++ concepts. To construct the generic space of two EL++ concepts, these need to be generalised in a controlled manner....
