Structure and phase transitions in ethylenediammonium dichloride and its salts with antimony trichloride
2000
During the mixing of ethylenediammonium dichloride and antimony trichloride except of reported earlier [NH3(CH2)2NH3]5(Sb2Cl11)2 · 4 H2O a new salt [NH3(CH2)2NH3](SbCl4)2 was obtained. The crystals are monoclinic at 295 K, space group C2/m, a = 13.829(3), b = 7.408(1), c = 7.588(2) Å; β = 103.18(3)°; V = 756.9(3) Å3; Z = 2; dc = 2.585, dm = 2.56(2) g · cm–3. The structure consists of anionic sublattice built of Sb2Cl82– units composed of two SbCl52– square pyramids connected by edge. The ethylenediammonium cations are located in anionic cavities. The cations are disordered. Each methylene carbon atom is split between two positions. The X‐ray diffraction, DSC, TGA and dilatometric methods we…
'Ardono le mie unghie e i miei pori'. Il corpo violentato nella letteratura testimoniale cilena.
2017
Pinochet (1973-1990) il corpo dei detenuti occupa uno spazio d’eccezione. Non c’è da sorprendersi, se si considera che era stata la logica stessa della repressione a porre il corpo al centro della propria strategia politica, produzione discorsiva e pratica militare. Né si tratta certo di una novità, visto che molti dei regimi repressivi che hanno fatto ricorso a retoriche massimaliste e a politiche del terrore hanno collocato il corpo nel fulcro delle loro strategie discorsive e militari; nel caso cileno, tuttavia, tale presenza ha intrapreso un percorso specifico, che molte delle testimonianze dei sopravvissuti alla violenza hanno cercato di rappresentare in diversi modi. In primo luogo, i…
Compensation appraisal processes for the realization of hydraulic works in an agricultural area.
2015
The present work aims to rationalize the process of the damages valuation for the construction of hydraulic works, considering the economic and evaluative aspects. The study deal with the damages in the sense of ex post and ex ante valuation for the task of environmental protection and the temporary employment. In this process are examined the technical and practical implications. The problem of the ex post compensation is proposed in the form of an income statement. The valuation of the ex ante damage, during the design of interventions of hydraulic nature, affect the taxation of the hydraulic constraint and the avoided future damages, to compensate in advance. The valuation of the indemni…
Data-Driven Interactive Multiobjective Optimization Using a Cluster-Based Surrogate in a Discrete Decision Space
2019
In this paper, a clustering based surrogate is proposed to be used in offline data-driven multiobjective optimization to reduce the size of the optimization problem in the decision space. The surrogate is combined with an interactive multiobjective optimization approach and it is applied to forest management planning with promising results. peerReviewed
Data-Driven Evolutionary Optimization: An Overview and Case Studies
2019
Most evolutionary optimization algorithms assume that the evaluation of the objective and constraint functions is straightforward. In solving many real-world optimization problems, however, such objective functions may not exist, instead computationally expensive numerical simulations or costly physical experiments must be performed for fitness evaluations. In more extreme cases, only historical data are available for performing optimization and no new data can be generated during optimization. Solving evolutionary optimization problems driven by data collected in simulations, physical experiments, production processes, or daily life are termed data-driven evolutionary optimization. In this…
A data-driven surrogate-assisted evolutionary algorithm applied to a many-objective blast furnace optimization problem
2017
A new data-driven reference vector-guided evolutionary algorithm has been successfully implemented to construct surrogate models for various objectives pertinent to an industrial blast furnace. A total of eight objectives have been modeled using the operational data of the furnace using 12 process variables identified through a principal component analysis and optimized simultaneously. The capability of this algorithm to handle a large number of objectives, which has been lacking earlier, results in a more efficient setting of the operational parameters of the furnace, leading to a precisely optimized hot metal production process. peerReviewed
Data-driven Interactive Multiobjective Optimization : Challenges and a Generic Multi-agent Architecture
2020
In many decision making problems, a decision maker needs computer support in finding a good compromise between multiple conflicting objectives that need to be optimized simultaneously. Interactive multiobjective optimization methods have a lot of potential for solving such problems. However, the growth of complexity in problem formulations and the abundance of data bring new challenges to be addressed by decision makers and method developers. On the other hand, advances in the field of artificial intelligence provide opportunities in this respect. We identify challenges and propose directions of addressing them in interactive multiobjective optimization methods with the help of multiple int…
Interactive evolutionary multiobjective optimization with modular physical user interface
2022
© 2022 Copyright held by the owner/author(s). Incorporating the preferences of a domain expert, a decision-maker (DM), in solving multiobjective optimization problems increased in popularity in recent years. The DM can choose to use different types of preferences depending on his/her comfort, requirements, or the problem being solved. Most papers, where preference-based and interactive algorithms have been proposed, do not pay attention to the user interfaces and input devices. If they do, they use character or graphics-based preference input methods. We propose the option of using a physical or tactile input device that gives the DM a better sense of control over providing his/her preferen…
On approaches for solving computationally expensive multiobjective optimization problems
2016
In this thesis, we consider solving computationally expensive multiobjective optimization problems that take into account the preferences of a decision maker (DM). The aim is to support the DM in identifying the most preferred solution for problems that have several conflicting objectives and when the evaluation of the candidate solutions is time consuming. This is conducted by replacing computationally expensive functions with computationally inexpensive functions, known as surrogates. First, based on a literature survey, we introduce two frameworks, i.e., a sequential and an adaptive framework, based on which surrogate-based methods are classified and compared. We then identify relevant cha…
Alcune osservazioni su recenti provvedimenti legislativi in tema di concessioni demaniali per finalità turistico-ricreative
2021
L’articolo, prendendo le mosse dalla recente legge regionale siciliana n. 32 del 2020, ripercorre le tappe relative alla più recente produzione normativa in tema di concessioni turistico-balneari, alla luce anche dei principi eurounitari (Direttiva Bolkestein, in particolare) e dei conseguenti interventi della Commissione, che ha avviato procedure di infrazione nei confronti dell’Italia. The paper, starting from the recent Sicilian regional law no. 32 of 2020, retraces the steps related to the most recent legislation on the subject of beach concessions for touristic and recreational purposes, also in light of the Euro-unitary principles (Bolkestein Directive, in particular) and the conseque…
