ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data
by antonio.pievatolo＠cnr.it 19 Jan '17

19 Jan '17

Call for papers *ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data* Monastery of Schlägl in Upper Austria, from 28th to 30th May, 2017 Abstract submission deadline: *26 February 2017* Web page: http://www.enbis.org/activities/events/current/533_ENBIS_Spring_Meeting_201… Description The meeting will focus on predictive maintenance and reliability with big and complex data. Industrial statistics and in particular reliability engineering is a strongly growing field of interest as technical products determine more and more our daily life (communication, mobility, logistics, energy, nutrition, etc.). This dependence motivates the importance of high reliability of processes and devices. The 2017 ENBIS Spring Meeting will contribute to the discussion of current problems and challenges in reliability and maintenance and to the exchange of knowledge among experts from industry, consultancy and academia. The meeting will focus on the application of statistical methods in the contemporary big data and internet of things context, where the sustained flow of failure and maintenance data can be of great value for prognosis and decision making if properly integrated with data analytic methods. Contributions are welcome on the illustration of particularly challenging reliability and maintenance problems, as well as on methodologies such as stochastic modelling, association modelling and data analysis methods designed for big data. -- Dr Antonio Pievatolo IMATI-CNR http://www.imati.cnr.it/joomla/index.php/people?layout=edit&id=101

Our proof is based upon adecomposition of the Euler-Poincaré Characteristic into differentWiener-chaos components: we prove that its asymptotic behaviour isdominated by a single term, corresponding to the chaotic component oforder two. As a consequence, we show how the asymptotic dependence on the threshold level u is fully degenerate, i.e. the Euler-PoincaréCharacteristic converges to a single random variable times a deterministicfunction of the threshold. This deterministic function has a zero at theorigin, where the variance is thus asymptotically of smaller order. Ourresults can be written as an asymptotic second-order Gaussian KinematicFormula for the excursion sets of Gaussian spherical harmonics.Based on a joint work with Valentina Cammarota.* *Prossimo seminario: Valentina Cammarota, 31/1* *Tutti gli interessati sono invitati ad intervenire.* *Per richieste di informazioni scrivere a piccioni(a)mat.uniroma1.it.*

Following the paradigm of preferential attachment, these models offer a simple explanation to why power laws can be observed in real-life networks such as the world wide web. The basic rule is that when new nodes are introduced into the network, they prefer to establish connections to old nodes that already have many connections. In this project we will consider the preferential network model with fitness. Here, the classical preferential attachment mechanism is modified by equipping each node with a random fitness. This models the fact that not every new node in a real-life network has the same initial attractiveness. The aim of the project is to understand how this extra randomness modifies the structure of the network. The mathematical analysis is closely related to studying processes in random environment and in particular to non-homogeneous branching processes. > > The project will be based at the internationally recognised probability laboratory at the University of Bath and the PhD candidate would benefit from a vibrant research environment and the interaction with other postgraduate students and other specialists working on closely related topics. >

de Finetti Risk Seminar - January 24, 2017
by Emanuela Rosazza 17 Jan '17

17 Jan '17

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture TITLE: Partial Differential Equations (PDEs) in Infinite Dimension: Economic and Financial models Fausto Gozzi LUISS, Italy ABSTRACT: "PDEs in Infinite Dimension" seems, already from the name, a very abstract and difficult subject. We aim to show how it can be very useful in treating, in particular, economic and financial models. We start by presenting some motivating problems in Economic and Finance (e.g. Growth and Pricing/Hedging) which can be naturally attacked using, as main mathematical tools, infinite dimensional PDEs. We then point out the state of the art on these kind of problems and present some recent results on them. Finally we will discuss the applicability of such results to the motivating problems and give some ideas on possible future developments. LOCATION: The seminar will be held on Tuesday, January 24, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 19.00. Scientific Committee Prof. Simone Cerreia-Voglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ.

----- Annuncio Seminario di Probabilità, Pisa ---- Dipartmento di Matematica, Università di Pisa Mercoledi, 18 gennaio, ore 11:00, Sala Riunioni. Seminario di Probabilità SPEAKER 1: Dario Trevisan, Universita di Pisa TITLE: A PDE approach to a 2-dimensional matching problem ABSTRACT: We prove asymptotic results for 2-dimensional random matching problems. In particular, we obtain the leading term in the asymptotic expansion of the expected quadratic transportation cost for empirical measures of two samples of independent uniform random variables in the square. Our technique is based on a rigorous formulation of the challenging PDE ansatz by S. Caracciolo et al. (Phys. Rev. E, 90, 012118, 2014) that linearizes the Monge-Ampère equation. Moreover, it provides a new approach to classical bounds due to Ajtai et al. (Combinatorica, 4, 1984). Joint work with L. Ambrosio and F. Stra. Dopo una pausa di circa 15min, proseguiamo con SPEAKER 2: Franco Flandoli, Università di Pisa TITLE: Sistemi di particelle (proseguimento): l'idea dell'equilibrio locale. ABSTRACT. Si prosegue la breve introduzione ai limiti macroscopici in diversi regimi approfondendo, pur solo euristicamente, il caso del limite idrodinamico, basato sull'idea di equilibrio locale. Tutti gli interessati sono invitati a partecipare. Per informazioni scrivere a carina.geldhauser(a)dm.unipi.it

Seminario di Tiziano De Angelis (School of Mathematics - The University of Leeds) Giovedi' 19 gennaio 2017 - ore 11:00 - aula 200 Università Cattolica del Sacro cuore, Milano, Dipartimento di di Discipline matematiche, Finanza matematica ed Econometria Viale Necchi, 9 - Milano TITLE: The dividend problem with a finite horizon ABSTRACT: We characterize the value function of the optimal dividend problem with a finite time horizon as the unique classical solution of a suitable Hamilton-Jacobi-Bellman equation. The optimal dividend strategy is realized by a Skorokhod reflection of the fund's value at a time-dependent optimal boundary. Our results are obtained by establishing for the first time a new connection between singular control problems with an absorbing boundary and optimal stopping problems on a diffusion reflected at an elastic boundary.
