Restoration of a XVII Century’s predella reliquary: From Physico-Chemical Characterization to the Conservation Process

2021

We report on the restoration of a XVII century’s predella reliquary, which is a part of a larger setup that includes a wall reliquary and a wooden crucified Christ, both belonging to the church of “Madre Maria SS. Assunta”, in Polizzi Generosa, Sicily, Italy. The historical/artistic and paleographic research was flanked successfully by the scientific objective characterization of the materials. The scientific approach was relevant in the definition of the steps for the restoration of the artefact. The optical microscopy was used for the identification of the wood species. Electron microscopy and elemental mapping by energy-dispersive X-ray (EDX) was successful in the identification of the l…

Why Use Interactive Multi-Objective Optimization in Chemical Process Design?

2008

Problems in chemical engineering, like most real-world optimization problems, typically, have several conflicting performance criteria or objectives and they often are computationally demanding, which sets special requirements on the optimization methods used. In this chapter, we point out some shortcomings of some widely used basic methods of multi-objective optimization. As an alternative, we suggest using interactive approaches where the role of a decision maker or a designer is emphasized. Interactive multi-objective optimization has been shown to suit well for chemical process design problems because it takes the preferences of the decision maker into account in an iterative manner tha…

PALABRAS MORALES EN LAS CONSTITUCIONES. UNA CUESTIÓN DE LECTURAS

2012

Resumen: El presente trabajo pretende indagar y analizar las fuentes de significado de las diferentes referencias morales contenidas en las constituciones. El trabajo, así, envolverá varias posibles interpretaciones o “lecturas” acerca de tales fuentes de significado. Por ejemplo, se analizará una lectura intencional, una lectura literal, una lectura moral, una lectura pragmática. Todas ellas consecuentes con los tipos de interpretación más usuales en la literatura iusfilosófica actual. Tras apuntar los diversos inconvenientes de todas esas lecturas, en el trabajo se apostará por una “lectura personal”, es decir, por la subjetividad como fuente de significado de las palabras morales en las …

The Human Right to Social Security and Its Impact on Socio-Political Action in Germany and Finland

2017

Social human rights have rarely been given attention in social work research or comparative studies on welfare states. The paper aims at filling the gap by analysing the conception of human beings inherent in human rights and in unemployment policy documents in Germany and Finland. Its focus lies on the right to social security, a central norm of the International Covenant on Economic, Social and Cultural Rights. The main question is what impact does the right to social security have on socio-political action in Germany and Finland. The results of the analysis, which was based on the objective hermeneutics, revealed a structural similarity between the conceptions of human beings in both cou…

A multi-objective Pareto design approach for simultaneous control of thinning and springback in complex stamping operations.

2009

Abstract In sheet metal forming operations design, optimization problems have to be solved in order to reach optimal process conditions. In these problems, there are some crucial issues to be taken into account: - most of the problems are multi objective problems, generally characterized by conflicting objectives: the definition of proper parameters aimed to prevent both springback and fracture is a typical example of an optimization problem in sheet metal forming characterized by conflicting goals; - in an industrial environment a great interest would be focused on the availability of a cluster of possible optimal solutions instead of a single “almost optimal” solution. Taking into account…

Rethinking Vygotskian Cultural-Historical Theory in Light of Pepperian Root Metaphor Theory : Dynamic Interplay of the Organicism and Contextualism

2016

This article examines Vygotskian cultural-historical theory by putting it into dialogue with Stephen Pepper's root metaphor theory. I focus on Vygotsky's insistence on the dialectical unity of the phylogenetic and ontogenetic domains in ontogenesis, which he articulated in his account of how the natural-psychological and cultural-psychological lines of development merge with the emergence of speeching in ontogenesis. I compare Vygotsky's two genetic domains and Pepper's world hypotheses of organicism and contextualism. I argue that Vygotsky transcended what is often thought of as a fundamental dichotomy between organicism and contextualism. In accomplishing this effective reconciliation, Vy…

Agent assisted interactive algorithm for computationally demanding multiobjective optimization problems

2015

We generalize the applicability of interactive methods for solving computationally demanding, that is, time-consuming, multiobjective optimization problems. For this purpose we propose a new agent assisted interactive algorithm. It employs a computationally inexpensive surrogate problem and four different agents that intelligently update the surrogate based on the preferences specified by a decision maker. In this way, we decrease the waiting times imposed on the decision maker during the interactive solution process and at the same time decrease the amount of preference information expected from the decision maker. The agent assisted algorithm is not specific to any interactive method or s…

Exact extension of the DIRECT algorithm to multiple objectives

2019

The direct algorithm has been recognized as an efficient global optimization method which has few requirements of regularity and has proven to be globally convergent in general cases. direct has been an inspiration or has been used as a component for many multiobjective optimization algorithms. We propose an exact and as genuine as possible extension of the direct method for multiple objectives, providing a proof of global convergence (i.e., a guarantee that in an infinite time the algorithm becomes everywhere dense). We test the efficiency of the algorithm on a nonlinear and nonconvex vector function. peerReviewed

Wastewater treatment: New insight provided by interactive multiobjective optimization

2011

In this paper, we describe a new interactive tool developed for wastewater treatment plant design. The tool is aimed at supporting the designer in designing new wastewater treatment plants as well as optimizing the performance of already available plants. The idea is to utilize interactive multiobjective optimization which enables the designer to consider the design with respect to several conflicting evaluation criteria simultaneously. This is more important than ever because the requirements for wastewater treatment plants are getting tighter and tighter from both environmental and economical reasons. By combining a process simulator to simulate wastewater treatment and an interactive mul…
