Study on the tunnel pasteurizer in table olives processing

2014

The application of heat treatment is especially important in maintaining the organoleptic characteristics of fermented agro-food products, which potential consumers perceive as reflecting the quality of these foodstuffs. However, heat treatments can be cause of deterioration of many quality parameters of agro-food products including texture, intended as the consistency of the pulp. Pasteurization is one of the most important steps of the table olives packaging process; it is applied after that olives are properly treated for debittering process. In this study ‘Nocellara del Belice’ table olives produced in 2010 and packaged in glass jars, were subjected to pasteurization at industrial scale…

Sindrome del tunnel carpale: malattia professionale o patologia correlata al lavoro?

2011

La sindrome del tunnel carpale costituisce la più frequente neuropatia da compressione dell’arto superiore, originando dall’intrappolamento del nervo mediano nel canale carpale. Nel determinismo della sua comparsa risultano coinvolti numerosi fattori (precedenti fratture, traumatismi cronici, sport, hobbies, attività casalinghe). Vieppiù, è noto che tale malattia riconosce come primo momento etiopatogenetico non solo ripetuti movimenti di flesso-estensione del polso, ma anche malattie sistemiche o condizioni parafisiologiche (menopausa, gravidanza). La sindrome del tunnel carpale, se “secondaria” si manifesta generalmente con carattere di bilateralità soprattutto in donne tra i 30 ed i 60 a…

A measurement-based channel model for vehicular communications in tunnels

2014

Wireless Communications and Networking Conference (WCNC), 2014 IEEE, Istanbul, TURQUIE, 06-/04/2014 - 09/04/2014; In this paper, we present a new version of the iterative nonlinear least square approximation (INLSA) algorithm for the design of measurement-based channel simulators. The proposed method aims to match the time-variant impulse response (TVIR) of the simulation model to that of the measured channel. The propagation delays are discerned directly from the measurements, whereas the gains, the Doppler frequencies, and the phases are computed iteratively by minimizing a matching error norm. We evaluate the performance of the proposed method in terms of the approximation of the transfe…

Magnetic domain-wall racetrack memory for high density and fast data storage

2012

The racetrack memory device is a new concept of Magnetic RAM (MRAM) based on controlling domain wall (DW) motion in ferromagnetic nanowires. It promises ultra-high storage density thanks to the possibility to store multiple narrow DWS per memory cell. By using read and write heads based on magnetic tunnel junctions (MTJ) with perpendicular magnetic anisotropy (PMA) fast data access speed can also be achieved. Thereby the racetrack memory can be used as universal storage to address both embedded and standalone applications. In this paper, we present the device physics, integration circuit and architecture designs of a racetrack memory based on MTJs with PMA. Mixed SPICE simulations at 65 nm …

Quantum dissipative dynamics of a bistable system in the sub-Ohmic to super-Ohmic regime

2016

We investigate the quantum dynamics of a multilevel bistable system coupled to a bosonic heat bath beyond the perturbative regime. We consider different spectral densities of the bath, in the transition from sub-Ohmic to super-Ohmic dissipation, and different cutoff frequencies. The study is carried out by using the real-time path integral approach of the Feynman-Vernon influence functional. We find that, in the crossover dynamical regime characterized by damped \emph{intrawell} oscillations and incoherent tunneling, the short time behavior and the time scales of the relaxation starting from a nonequilibrium initial condition depend nontrivially on the spectral properties of the heat bath.

Resonant Transitions Due to Changing Boundaries

2019

The problem of a particle confined in a box with moving walls is studied, focusing on the case of small perturbations which do not alter the shape of the boundary (\lq pantography\rq). The presence of resonant transitions involving the natural transition frequencies of the system and the Fourier transform of the velocity of the walls of the box is brought to the light. The special case of a pantographic change of a circular box is analyzed in dept, also bringing to light the fact that the movement of the boundary cannot affect the angular momentum of the particle.
