The promise of spintronics for unconventional computing

2021

Novel computational paradigms may provide the blueprint to help solving the time and energy limitations that we face with our modern computers, and provide solutions to complex problems more efficiently (with reduced time, power consumption and/or less device footprint) than is currently possible with standard approaches. Spintronics offers a promising basis for the development of efficient devices and unconventional operations for at least three main reasons: (i) the low-power requirements of spin-based devices, i.e., requiring no standby power for operation and the possibility to write information with small dynamic energy dissipation, (ii) the strong nonlinearity, time nonlocality, and/o…

On thrusting, regional unconformities and exhumation of high-grade greenstones in Neoarchean orogens. The case of the Waroonga Shear Zone, Yilgarn Cr…

Abstract During the Neoarchean, the dominant tectonic style progressively changed from an episodic-overturn/stagnant-lid regime to modern-style plate tectonics. The Neoarchean strengthening of continental lithosphere changed the style of deformation of orogenic belts. The case study presented here provides insights into how such transition in tectonic style occurred, a matter that is generally controversial. We present structural and metamorphic data from the c. 2660 Ma Waroonga Shear Zone (WSZ) in the Neoarchean Yilgarn orogen (Western Australia). The WSZ contains a syntectonic pluton and older, high-grade greenstones. The tectonic fabric in the pluton developed during melt-present thrusti…

A Reinforcement Learning Approach for User Preference-aware Energy Sharing Systems

2021

Energy Sharing Systems (ESS) are envisioned to be the future of power systems. In these systems, consumers equipped with renewable energy generation capabilities are able to participate in an energy market to sell their energy. This paper proposes an ESS that, differently from previous works, takes into account the consumers’ preference, engagement, and bounded rationality. The problem of maximizing the energy exchange while considering such user modeling is formulated and shown to be NP-Hard. To learn the user behavior, two heuristics are proposed: 1) a Reinforcement Learning-based algorithm, which provides a bounded regret and 2) a more computationally efficient heuristic, named BPT- ${K}…

Integration of green roofs&walls in urban areas

2020

Growing urbanization is associated with the emergence of environmental problems, such as the reduction of natural resources, the atmosphere pollution and the increase of the heat islands phenomenon in cities. The integration of vegetation in the urban areas, through the creation of green hanging systems, represents a possible solution to improve the energy sustainability of buildings, to combat meteoric excesses, to improve stormwater management and to reduce pollutant levels. These energy and environmental benefits are related to the properties of evapotranspiration, shading and thermal insulation of the vegetation. The work reports the results of the main studies concerning the use of han…

Environmental Sustainability Orientation, Reward-Based Crowdfunding, and Venture Capital: The Mediating Role of Crowdfunding Performance for New Tech…

2021

Extant literature has investigated the effects of new ventures’ environmental sustainability orientation (ESO) on the crowdfunding (CF) performance and on the ability to secure venture capital, separately and with mixed results. In this article, we address the study of these relationships simultaneously. Specifically, we examine how the presence of ESO features influences new technology-based ventures’ ability to secure funding in reward-based CF campaigns and how the CF performance mediates the effect of such features on attracting subsequent venture capital. Using a sample of new hardware ventures that have launched a CF campaign on Kickstarter, we document a negative effect of the presen…

Territorial dissimilarities in energy and climate change

2013

This paper examines regional differences between EU Member States on climate change, green economy and energy in the context of the Europe 2020 strategy, based on current work undertaken for the ESPON SIESTA project . The strategy is a new key policy based on smart, sustainable and inclusive growth to help EU-27 facing global economic crisis and meeting the new environmental challenges such as energy efficiency, climate change, energy security and green economy. Drawing on the key findings and policy recommendations pointed out in the section “Sustainable growth” of the SIESTA project, this paper presents empirical data demonstrating the regional variations across Europe on a range of selec…
