Quantile based risk measures in cyber security

Measures and methods used in financial sector to quantify risk, have been recently applied to cyber world. The aim is to help organizations to improve risk management strategies and to wisely plan investments in cyber security. On the other hand, they are useful instruments for insurance companies in pricing cyber insurance contracts and setting the minimum capital requirements defined by the regulators. In this paper we propose an estimation of Value at Risk (VaR), referred to as Cyber Value at Risk in cyber security domain, and Tail Value at risk (TVaR).

Cyber Risk management: an actuarial point of view

In the last decades companies worldwide are facing a new kind of risk, namely cyber risk, that has emerged as one of the top challenges in risk management. Insurance was only recently applied to cyber world and it is increasingly becoming part of the risk management process, posing many challenges to actuaries. One of the main issues is the lack of data, in particular nancial ones.

Assessment of cumulative discriminant analysis for cloud detection in the ESA PROBA-V Round Robin exercise

Cloud detection is a critical issue for satellite optical remote sensing, since potential errors in cloud masking can be translated directly into significant uncertainty in the retrieved downstream geophysical products. The problem is particularly challenging when only of a limited number of spectral bands is available, and thermal infrared bands are lacking.

Effect of parameter selection on different topological structures for Particle Swarm Optimization algorithm

Particle Swarm Optimization is an evolutionary optimization algorithm, largely studied during the years: analysis of convergence, determination of the optimal coefficients, hybridization of the original algorithm and also the determination of the best relationship structure between the swarm elements (topology) have been investigated largely. Unfortunately, all these studies have been produced separately, and the same coefficients, derived for the original topology of the algorithm, have been always applied.

Hybridization of the imperialist competitive algorithm and local search with application to ship design optimization

In the wide scenario of the optimization techniques, a large number of algorithms are inspired by natural processes, in many different ways. One of the latest is the Imperialist Competitive Algorithm (ICA) Atashpaz-Gargari and Lucas (2007), judged by their authors as very efficient and competitive with other popular optimization algorithms. However, its diffusion is still limited, so that it has not yet been adequately studied.

Low and high resonance components restoration in multichannel data

A technique for the restoration of low resonance component and high res- onance component of K independently measured signals is presented. The definition of low and high resonance component is given by the Rational Dilatation Wavelet Transform (RADWT), a particular kind of finite frame that provides sparse repre- sentation of functions with different oscillations persistence.

HiCeekR: A Novel Shiny App for Hi-C Data Analysis

The High-throughput Chromosome Conformation Capture (Hi-C) technique combines the power of the Next Generation Sequencing technologies with chromosome conformation capture approach to study the 3D chromatin organization at the genome-wide scale. Although such a technique is quite recent, many tools are already available for pre-processing and analyzing Hi-C data, allowing to identify chromatin loops, topological associating domains and A/B compartments. However, only a few of them provide an exhaustive analysis pipeline or allow to easily integrate and visualize other omic layers.

Sintesi di immagini: risultati e prodotti delle ricerche svolte nei sottoprogetti 1 e 2 del progetto finalizzato: sistemi informatici e calcolo parallelo

Il Progetto Finalizzato "Sistemi Informatici e Calcolo Parallelo" è stato negli ultimi anni l'unica iniziativa a livello nazionale che ha avuto come obiettivo fondamentale lo sviluppo di ricerche avanzate e di prodotti innovativi nel campo dell'informatica, con particolare riferimento anche al calcolo parallelo. Per innalzare il livello tecnico-scientifico della comunità nazionale nel settore, il Progetto si è posto come obiettivo essenziale di favorire lo sviluppo di teorie e tecnologie avanzate, in grado di migliorare le conoscenze e le competenze sia metodologiche sia implementative.
