Fuzzy Control of Uncertain Nonlinear Systems with Numerical Techniques: A Survey
2019
This paper provides an overview of numerical methods in order to solve fuzzy equations (FEs). It focuses on different numerical methodologies to solve FEs, dual fuzzy equations (DFEs), fuzzy differential equations (FDEs) and partial fuzzy differential equations (PFDEs). The solutions which are produced by these equations are taken to be the controllers. This paper also analyzes the existence of the roots of FEs and some important implementation problems. Finally, several examples are reviewed with different methods.
Die Wissenschaftsübersetzung als Generator symbolischen Kapitals
2021
ZusammenfassungThis paper investigates the function of translation in the context of scientific communication, examining the correspondence between the Italian universal scientist Lazzaro Spallanzani, his translator Jean Senebier, and the Swiss naturalist Charles Bonnet. The main thesis is that the function of scientific translation goes far beyond the simple communication of scientific content and that it in fact played a complex role in the system of exchange and circulation of symbolic capital within the scientific community in the Early Modern Period. To illustrate the complexity of scientific translation, the paper focusses on Spallanzani’s remarkable adoption of a twofold perspective:…
"The Referee Plays to Be Insulted!": An Exploratory Qualitative Study on the Spanish Football Referees' Experiences of Aggression, Violence, and Copi…
2021
Referees are essential participants in the sport of football. They are responsible for enforcing the rules and achieving the necessary impartiality for the matches. Referees are often target of hostile reactions from fans, players, and coaches. However, few studies have focused on these experiences and the strategies they use to manage them. In order to fill this gap, a qualitative interview-based study was developed to explore the experiences of a group of football referees (four males and four females) on aggression, violence, and coping. A thematic analysis was developed combining inductive and deductive processes. Results indicated that the most frequent aggressions experienced were ver…
Elementary Integration of Superelliptic Integrals
2021
Consider a superelliptic integral $I=\int P/(Q S^{1/k}) dx$ with $\mathbb{K}=\mathbb{Q}(\xi)$, $\xi$ a primitive $k$th root of unity, $P,Q,S\in\mathbb{K}[x]$ and $S$ has simple roots and degree coprime with $k$. Note $d$ the maximum of the degree of $P,Q,S$, $h$ the logarithmic height of the coefficients and $g$ the genus of $y^k-S(x)$. We present an algorithm which solves the elementary integration problem of $I$ generically in $O((kd)^{\omega+2g+1} h^{g+1})$ operations.
Incomplete Riemann Solvers Based on Functional Approximations to the Absolute Value Function
2021
We give an overview on the work developed in recent years about certain classes of incomplete Riemann solvers for hyperbolic systems. These solvers are based on polynomial or rational approximations to |x|, and they do not require the knowledge of the complete eigenstructure of the system, but only a bound on the maximum wave speed. Our solvers can be readily applied to nonconservative hyperbolic systems, by following the theory of path-conservative schemes. In particular, this allows for an automatic treatment of source or coupling terms in systems of balance laws. The properties of our schemes have been tested with some challenging numerical experiments involving systems such as the Euler…
Block 21 and the Pensabilità of the Representation of Auschwitz
2012
Abstract Building on the assumption that the Memorial in Honor of Italians Fallen in Nazi Extermination Camps (situated in Auschwitz I, Block 21) expresses the meta-reflexive inclination that strengthened the twentieth century (the capacity of that century to think of itself as a subject), this article aims to highlight and illustrate the dual philosophical significance of the Memorial. From the perspective of the philosophy of history, this philosophical significance, which has a symbolic value, leads us to investigate an organic and historically embodied conception of deportation. From the perspective of the aesthetics of memory, this philosophical meaning offers a new framework for the …
From heritage to hyper-reality? Tourism destination development in the Middle East between Petra and the Palm
2010
Tourism destination development in the Middle East and North Africa (MENA) has been remarkably strong in the last few years, but different types of destinations vary in terms of degree of success. While classical European-centred heritage tourism destinations, such as the Nile valley in Egypt and Petra in Jordan, have been stagnating, other destinations, such as Egypt's coastal resort of Sharm El-Sheikh and the emirate of Dubai, are booming. The expansion in the latter destinations has been enhanced by the construction of new development projects such as El Gouna, Ibn Battuta Mall, Burj Al Arab, and The Palm Islands. Drawing on the work of Eco and Baudrillard, this article interprets these …
The minimal free resolution of fat almost complete intersections in ℙ1 x ℙ1
2017
AbstractA current research theme is to compare symbolic powers of an ideal I with the regular powers of I. In this paper, we focus on the case where I = IX is an ideal deûning an almost complete intersection (ACI) set of points X in ℙ1 × ℙ1. In particular, we describe a minimal free bigraded resolution of a non-arithmetically Cohen-Macaulay (also non-homogeneous) set 𝒵 of fat points whose support is an ACI, generalizing an earlier result of Cooper et al. for homogeneous sets of triple points. We call 𝒵 a fat ACI.We also show that its symbolic and ordinary powers are equal, i.e, .
Symbolic and conceptual representation of dynamic scenes: Interpreting situation calculus on conceptual spaces
2001
In (Chella et al. [1,2]) we proposed a framework for the representation of visual knowledge, with particular attention to the analysis and the representation of scenes with moving objects and people. One of our aims is a principled integration of the models developed within the artificial vision community with the propositional knowledge representation systems developed within symbolic AI. In the present note we show how the approach we adopted fits well with the representational choices underlying one of the most popular symbolic formalisms used in cognitive robotics, namely the situation calculus.
