Quel S. Giacomo (e altri dipinti) di Nicola Cacciapuoti a Monteforte
No full textAttraverso un attento studio di ricerca l’autore attribuisce i dipinti che sono nell’altare maggiore della Chiesa di San Nicola a Monteforte Irpino al pittore giuglianese Nicola Cacciapuoti, allievo del Solimena e di Domenico Antonio Vaccaro. In particolare egli evidenzia l’accostamento del Cacciapuoti, tra il 1742 e il 1748, anche allo stile di Francesco De Mura. Attraverso un’analisi stilistica ed iconografica dei dipinti, emerge la figura di Nicola Cacciapuoti, di considerevole spessore culturale e protagonista nell’ambito della pittura della prima metà del Settecento nel Meridione. Il lavoro contribuisce a far luce su un pittore sinora ancora non sufficientemente conosciuto ed ap prezzato come merita.Through a careful research study, the author attributes the paintings that are in the high altar of the Church of San Nicola in Monteforte Irpino to the Giugliano’s painter Nicola Cacciapuoti, a pupil of Solimena and Domenico Antonio Vaccaro. In particular, he highlights the combination of Cacciapuoti, between 1742 and 1748, with the style of Francesco De Mura. Through a stylistic and iconographic analysis of the paintings, the considerable cultural value of Nicola Cacciapuoti emerges as protagonist in the painting of the first half of the eighteenth century in the South Italy. The current study helps to shed light on a painter not yet sufficiently known and appreciated as he deserves

A scalable Kalman Filter algorihm: trustworthy analysis on constrained least square model
No full textKalman filter (KF) is one of the most important and common estimation algorithms. We introduce an innovative designing of Kalman filter algorithm based on domain decomposition (we call it DD‐KF). DD‐KF involves decomposition of the whole computational problem, partitioning of the solution and a slight modification of KF algorithm allowing a correction at run‐time of local solutions. The resulted parallel algorithm consists of concurrent copies of KF algorithm, each one requiring the same amount of computations on each subdomain and an exchange of boundary conditions between adjacent subdomains. Main advantage of this approach is that it can be potentially applied in a moderately nonintrusive manner to existing codes for tracking and controlling systems in location, navigation, in computer graphics and in much more state estimation problems. To highlight the capability of DD‐KF of exploiting the computing power provided by future designs of microprocessors based on multi/many‐cores CPU/GPU technologies, we consider DD both at physical core level and at microprocessor level and we discuss scalability of DD‐KF algorithm at coarse and fine grained level. Throughout the present work, we derive and discuss DD‐KF algorithm for solving constrained least square model, which underlies any data sampling and estimation problem
Self-organizing strategy design for heterogeneous coexistence in the Sub-6 GHz
No full textDue to the worldwide ongoing pressure to massively exploit the Sub-6 GHz spectrum for the deployment of independently-operated and heterogeneous networks, innovative solutions for network coexistence are deeply required. Hence, in this paper, we design a self-organizing strategy with the aim of minimizing the coexistence interference among heterogeneous networks sharing the Sub-6 GHz spectrum. The design is performed under the constraints of promoting selfless network utilization and avoiding any direct communication among the heterogeneous networks. For this, we develop an analytical framework, grounded on the nest-site selection behavior observed in honeybee swarms, to model the coexistence problem among multiple heterogeneous networks. Specifically, first, different heterogeneous networks are mapped into different populations and the allocation of a Sub-6 GHz band to a network is mapped into the population commitment. Then, the evolution of the commitment process is described through a multi-dimensional differential system. We analytically study the stability of such a system at the equilibrium, and we derive the conditions that assure the optimal allocation of the available Sub-6 GHz bands among the different heterogeneous networks. Finally, the proposed strategy is validated through an extensive performance evaluation
Kreĭn formula and convergence of hamiltonians with scaled potentials in dimension one
No full textIn this brief report we study the convergence of the Hamiltonian hε := −(⋅)′′ + V (x∕ε)∕ε2 in dimension one as ε goes to zero. This problem has already been studied in several former works (also in the more general setting of metric graphs) and the results that we present here are not new. Aim of this work is to formulate the problem in the setting of metric graphs and to exploit an approach based on a Kreı̆n formula for the resolvent of hε. Such a formula allows to mark out the rôle of the zero eigenvalue for an auxiliary Hamiltonian. The existence of the zero eigenvalue is responsible of the coupling in the limiting Hamiltonian, otherwise hε converges in norm resolvent sense to the direct sum of two Dirichlet Laplacians on the half-line. In a forthcoming paper such approach will be generalized to the study of an analogous problem on metric graphs with a small compact core
