In this work we elaborated, by means of the novel 3D Reconstructing Cutting method, 5 sets of cadaver glenoids, scanned with dual-source CT. The obtained high-resolution models were used to print polylactic acid replicas of the 10 glenoids. The realization of these bionic target structures based on smart devices allows the design of neural networks, able to support the clinicians’ response for personalized clinical and surgical therapy planning, in keeping with the society 5.0 concept.

Hyper-Spectral Imaging (HSI) is gaining, as a diagnostic tool in the field of cultural heritage, an increasing interest and it has been largely utilized in the last decade tanks to its ability to obtain both spatial and spectral information from a sample. Furthermore, it is a consolidated practice, to perform a better sample characterization, to acquire multiple imaging data coming from different devices covering different spectral ranges. In the present study, we present an analytical approach based on data fusion strategies to classify layers of different pigments using hyperspectral images acquired in two spectral ranges: visible near infrared (Vis-NIR: 400–1000 nm) and short infrared wavelength infrared (SWIR: 1000–2500 nm). The main aim of the study was to combine the data acquired by the two HSI sensors following a multivariate approach to classify pigments, thanks to the complementary information collected in the different spectral regions.

Network operators have cope with the never stopping traffic growth and also with the new service dynamicity, due to the increase of data-center and 5G traffic, video service and caching. With multimedia traffic more and more dominant with respect to voice, network operators have reduced their revenues and need to reduce the overall network costs associated to the management. To deal with traffic and operator requirements, new control and management paradigms became necessary and are based mainly on software-defined networking (SDN) architecture, which improve network flexibility and manageability. In this paper we presented SMART-A, an SDN-application prototype able to reconfigure the optical network in case of defragmentation, due to the sub-optimal spectrum resource occupation, and re-routing, due to optical connection failure caused by physical degradation of the optical medium.

A complete theoretical model of an amplified spontaneous emission (ASE) source based on a Tm:Er:Yb:Ho co-doped germanate glass is developed. It is based on a nonlinear rate equations system, together with the power propagation equations for the pump and the ASE beams. The device is pumped at 980 nm. A particle swarm optimization (PSO) algorithm is used to find the best combination of the four dopants concentrations yielding an ASE spectrum as wide as possible. Preliminary results show that a broad spectrum ranging from 1480 nm to 2100 nm is obtained.

In this paper, an innovative Tm:Er:Yb:Ho co-doped germanate fiber glass amplifier, pumped at λp = 980 nm, is designed and optimized, to obtain a wideband/three band amplification in the wavelength range λ = 1.4 – 2.1 μm. A preliminary investigation has shown the dependence of the optical gain on the dopant concentrations, the fiber length and the pump power. To obtain a suitable three-band gain, a Particle Swarm Optimization (PSO) algorithm is applied in order to perform a global optimization.

Here we report about the development of a fiber optic based microfluidic sensor. It is based on a single-mode fiber having two micro-channels with a diameter of 28 μm, usually referred to as side-hole fiber (SHF). The setup for providing the fiber with both optical connection and access to the micro-channels for input/output of liquid solutions was developed. Moreover, to probe the refractive index of the substance inside the micro-channels, a long period grating (LPG) transducer was written in the SHF by electric arc discharge technique. Testing was conducted by using distilled water inside the channels, demonstrating the possibility to detect the presence of a liquid rapidly and consuming low sample volumes through the LPG response. This device can find application for bio-chemical sensing.
