The future of Cybersecurity in Italy: Strategic focus area

This volume has been created as a continuation of the previous one, with the aim of outlining a set of focus areas and actions that the Italian Nation research community considers essential. The book touches many aspects of cyber security, ranging from the definition of the infrastructure and controls needed to organize cyberdefence to the actions and technologies to be developed to be better protected, from the identification of the main technologies to be defended to the proposal of a set of horizontal actions for training, awareness raising, and risk management

The evolution of Life Cycle Assessment (LCA): some guide-lines for future research in the wine sector

The approach of Life Cycle Assessment (LCA) is an essential reference for the international scientific community in assessing the sustainability of economic activities. The purpose of this paper is to focus on the development prospects of the application of LCA in agricultural economics. Firstly we briefly summarized the evolution of this tool: from the environmental LCA to the LCSA (Life Cycle Social Assessment)  which considers the three aspects of sustainability in view of Life Cycle Thinking in order to highlight the drivers for  future researches. Then we carried out literature review on international applications in the wine industry. This exercise has been oriented  to highlight the used methodological approaches ,  investigate the economic and market already obtained results already,and propose some reflections about the consequences related to the use of conventional LCA and finally to indicate the still poorly investigated fields of research

Memristor models for pattern recognition systems

The design of Memristor Oscillatory Neurocomputers for pattern recognition tasks may not leave aside a preliminary thorough investigation of the nonlinear dynamics of the whole system and its basic components. This chapter yields novel insights into the peculiar nonlinear dynamics of different memristor models. A detailed mathematical treatment aimed at highlighting the key impact the initial condition on the flux across a memristor with odd-symmetric charge-flux characteristic has on the development of a particular dynamical behavior. It is proved how, driving the memristor with a sine-wave voltage source, the amplitude-angular frequency ratio selects a sub-class of observable current-voltage behaviors from the class of all possible dynamics, while the initial condition on flux specifies which of the behaviors in the sub-class is actually observed. In addition, a novel boundary condition-based model for memristor nano-scale films points out how specification of suitable dynamical behavior at film ends, depending on the particular physical realization under study and on driving conditions, crucially determines the observed dynamic

Improved dual sided doped memristor: modelling and applications

Memristor as a novel and emerging electronic device having vast range of applications suffer from poor frequency response and saturation length. In this paper, the authors present a novel and an innovative device structure for the memristor with two active layers and its non-linear ionic drift model for an improved frequency response and saturation length. The authors investigated and compared the I–V characteristics for the proposed model with the conventional memristors and found better results in each case (different window functions) for the proposed dual sided doped memristor. For circuit level simulation, they developed a SPICE model of the proposed memristor and designed some logic gates based on hybrid complementary metal oxide semiconductor memristive logic (memristor ratioed logic). The proposed memristor yields improved results in terms of noise margin, delay time and dynamic hazards than that of the conventional memristors (single active layer memristors)
