A linear model of lung mechanics is analyzed in the following report. The model corresponds to an RLC circuit with unknown parameters. Parametric identification allows to trace the system governance coefficients once a mathematical model has been estimated. Different approaches allow to minimize the difference between the estimated parameters and Read more…
Pulmonary ventilation is a critical operation both during surgery and for assisted or replacement ventilation of the patient. This report proposes the analysis of a lung mechanics model through an electrical analogy with an equivalent circuit consisting of resistors and capacitors. This electrical-mechanical analogy makes it possible to analyze how Read more…
In the digital era, even in medicine, numerous images are produced every day and, despite their classification, the segmentation and recognition of objects are less detailed. With the recent development of artificial intelligence and convolutional neural network algorithms it is possible to achieve excellent results. This article analyzes the neural Read more…
In this period I had the opportunity to gain different experiences in the design and construction of antennas. In particular, the latest experiences have focused on the study and design of patch antennas and antenna arrays. The last opportunity, after the realization of the project for the Wireless Electromagnetics Technologies Read more…
In most phenomena it is often necessary to take into account, in addition to the mechanical characteristics, various other quantities. For example, it is important to analyze the variation over time of quantities such as temperature, thermal flows, current intensity, mass flow, concentration gradients, etc. Most biological tissues can be Read more…

Automated computational modeling (ACM) is a fairly recent technique that exploits a hybrid approach by combining symbolic computation with numerical computation. These potentialities can be exploited in finite element formulations so it is possible to automate some procedures, including derivation ones, by performing the calculations that until recently were carried Read more…
This image processing algorithm arises from the need to have a 3D volume starting from the slices of a CT. There are several algorithms online but most require DICOM images. In this case, the reference dataset is made up of 970 png images. Also, although the image is actually in Read more…
The following report introduces various simulation campaigns aimed at homogenizing trabecular bone tissue.Background, analyzing the structure of the trabecular bone it is evident how the shape of the pores and the trabecular structure influence the stiffness and the structural response. It is analyzed how the variation of the pore geometry Read more…
Modern computers have all the prerequisites for developing numerical resolution methods for a large class of physical problems that have been left without an analytical solution for years.
