Towards Positive Energy Districts: Energy Renovation of a Mediterranean District and Activation of Energy Flexibility
2023
The paper presents the analysis of energy retrofitting, integration of renewable energy and activation of energy flexibility in a cluster of buildings in the surroundings of a port on the Mediterranean Sea in Southern Italy, with the aim of checking the potential for it to achieve the status of positive energy district (PED). The objective of this study is to improve the contemporaneity between local energy generation and energy demand and reduce CO2eq emissions by considering signals that reflect the environmental variability of the electricity grid, through flexibility solutions applied to the HVAC system. The proposed scenarios are based on the dynamic simulation of the district and anal…
Dynamic response of equivalent orthotropic plate model for stiffened plate: numerical-experimental assessment
2017
Abstract Over the last two decades, homogenization-based modeling techniques have attracted considerable attention. In fact, through these methods, structures such as corrugated or stiffened plates, commonly referred to as structurally orthotropic plates, can be approximately studied as equivalent flat plates with orthotropic behavior. Specifically, these homogenization techniques allow for the direct determination of the equivalent flexural and torsional rigidities which appear in the governing equation for the deflection of the equivalent orthotropic plate. It is worth noting that, the determined equivalent material properties retain the dependence on the geometric parameters of the origi…
Electrodialysis for water desalination: A critical assessment of recent developments on process fundamentals, models and applications
2018
Abstract The need for unconventional sources of fresh water is pushing a fast development of desalination technologies, which proved to be able to face and solve the problem of water scarcity in many dry areas of the planet. Membrane desalination technologies are nowadays leading the market and, among these, electrodialysis (ED) plays an important role, especially for brackish water desalination, thanks to its robustness, extreme flexibility and broad range of applications. In fact, many ED-related processes have been presented, based on the use of Ion Exchange Membranes (IEMs), which are significantly boosting the development of ED-related technologies. This paper presents the fundamentals…
Flexibility of grid interactive water heaters: The situation in the US
2023
Among different solutions to increase flexibility of electricity system, grid interactive water heaters (GIWHs) can make a large contribution, against a relatively low cost. They can advantageously be used within a single building, a local energy community or within an entire distribution grid, thanks to the very fast response time, low cost, highly distributed resource and widely demonstrated technology. In the near future, the flexibility potential of GIWHs will certainly increase, thanks to the advantageous flexibility programs that have been implementing in some area of the world, with the aim of coordinating several million of GIWHs with the electricity network. In this study, we asses…

Input for baroreflex analysis: which blood pressure signal should be used?
2022
The baroreflex (BR) is an important physiological regulatory mechanism which reacts to blood pressure perturbations with reflex changes of target variables such as the heart period (electrocardiogram derived RR interval) or the peripheral vascular resistance (PVR). Evaluation of cardiac chronotropic (RR as a target variable) and vascular resistance (target PVR) BR arms was in previous studies mainly based on the use of the spontaneous variability of the systolic or diastolic blood pressure (SBP, DBP), respectively, as the input signals. The use of other blood pressure measures such as the mean blood pressure (MBP) as an input signal for BR analysis is still under investigation. Making the a…
Enti pubblici economici, società controllate dalle pubbliche amministrazioni e lavoro flessibile.
2020
The paper analyses the recent developments of the Italian legislation regarding flexible con-tracts in the societies controlled by public administrations. It aims to demonstrate that such developments are deeply rooted in the Italian jurisprudence’s traditional approach to the topic, with some differences, originating by the European Court of Justice influence
Undeclared, informal, and precarious workform "social pollution" to “decent work” trough “nonwage security tax”
2015
The paper, basing on a multidisciplinary literature, considers flexicurity as any balance between flexibility and security and, therefore, proposes ordering any set of work-relationship, providing the same balance and with the same regulatory framework, in “communities”. It is assumed, therefore, that communities can differ either in terms of a “protective” trade-off, where the differential is not a surrogate measure of security, or in terms of an economic trade-off, where it is met by the provision of social insurance or security. One of these sets is called community 0 and it corresponds to undeclared work, not only illegal (e.g. informal), but also completely devoid of security and fully…
Lavoro e sicurezza sociale in agricoltura: breve analisi del mercato del lavoro agricolo (in Sicilia) alla scoperta della flexicurity ante litteram
2012
L'articolo propone un confronto tra tra i percorsi di flexicurity e il sistema del mercato del lavoro agricolo e relative misure di sicurezza sociale.
