This paper \u0000presents an electromechanical-traffic model for roadway compression-based piezoelectric energy harvesting system. \u0000A two-degree-of-freedom (2-DOF) electromechanical model has been developed for the piezoelectric energy \u0000harvesting unit to define its performance in power generation under a number of external excitations on road surface. \u0000Lead Zirconate Titanate (PZT-5H) is selected as the piezoelectric material to be used in this paper due to its high \u0000Piezoelectric Charge Constant (d) and Piezoelectric Voltage Constant (g) values. The main source of vibration energy \u0000that has been considered in this paper is the moving vehicle on the road. The effect of various frequencies on possible \u0000generated power caused by different vibration characteristics of moving vehicle has been studied.

The \u0000estimated power to be generated for multiple arrays of PCT is approximately 150 kW/ km.

Germanium diodes enriched to ∼ 86 % in the double beta emitter Ge(Ge) are exposed being both source and detectors of 0νββ decay. Neutrinoless double beta decay is considered a powerful probe to address still open issues in the neutrino sector of the (beyond) Standard Model of particle Physics. Since 2013, just after the completion of the first part of its experimental program (Phase I), the GERDA setup has been upgraded to perform its next step in the 0νββ searches (Phase II). Phase II aims to reach a sensitivity to the 0νββ decay half-life larger than 10 yr in about 3 years of physics data taking. This exposing a detector mass of about 35 kg of Ge and with a background index of about 10−3 cts/(keV·kg·yr). One of the main new implementations is the liquid argon scintillation light read-out, to veto those events that only partially deposit their energy both in Ge and in the surrounding LAr. In this paper, the GERDA Phase II expected goals, the upgrade work and few selected features from the 2015 commissioning and 2016 calibration runs will be presented. The main Phase I achievements will be also reviewed.
