Locke o Spinoza: un punto di eresia
No full textRelying on his previous inquiries, the author discusses theories of “consciousness” which were elaborated almost simultaneously by Locke and Spinoza, as a reaction against the Cartesian doctrine of self-certainty. Because of their remarkable analogies and their sharp antithesis, they illustrate a “point of heresy” which, even today, intrinsically divides any project of framing a “psychology” or “philosophy of mind

Using the balanced scorecard framework /
No full text"... explains the balanced scorecard framework. Since its introduction in the early 1990s, the balanced scorecard framework has become a standard strategy execution and performance measurement system for many for-profit companies as well as for non-profit organizations and public sector entities. Scholars, including the author of this portfolio, Dr. Mark L. Frigo, have continued to refine this framework with cutting-edge managerial and accounting concepts.
Fausto Sozzini, la mortalità d’Adamo e la teologia moderna
No full textFausto Sozzini, Adam's Mortality and Early Modern Theology. In his dispute with Francesco Pucci, Fausto Sozzini argues that man was not created immortal but, being by nature subject to death, he could be made perpetually immune only through divine grace, which was a gift not included in his creation. It has thus been suggested that the Pucci-Sozzini querelle should be read as an expression of the broader debate that opposed the two 'souls' of modern theology, that is the Thomistic and the Augustinian. By reconstructing the late medieval theological debate on the mortality of Adam in the condition of innocence, the Author tries to show that Sozzini's theses are greatly indebted to Duns Scotus' criticisms of Thomas Aquinas
Energy and economic analysis of the local hydrogen production via electrolysis for industrial port districts
No full textIndustrial port districts are facing tough challenges in the decarbonization of their industrial and transport activities. To meet environmental requirements while maintaining economic competitiveness, ports are following several strategies to reduce their carbon footprint, e.g. the electrification and automation of the vehicle fleet, the onshore power supply for vessel stay at quay, the exploitation of Renewable Energy Sources (RES), and the use of alternative fuels and energy carriers. The combination of the last two points is a promising solution to reduce the carbon impact of industrial port districts. However, to increase the power generation from RES, the imbalance between supply and demand due to the intermittency and unpredictability of RES must be efficiently addressed. Despite the electrochemical battery systems are widely use as electric energy storage for power produced from RES, they are unfit for seasonal energy storage because of energy self-discharged and volume per unit of energy [1]. To overcome these technical limitations, several authors have proposed Power-to-X technologies, i.e. the RES are used to produce energy carriers which, in turn, are used when/where it is needed. Accordingly, it could be possible to store and transport energy produced from RES on a seasonal basis [2,3]. In particular, the hydrogen produced using RES (i.e., green hydrogen) could be employed to decarbonize both hard-to-abate industry sectors and heavy-duty transport typically located in industrial port districts [4]. In fact, ports are usually contiguous to industrial areas (e.g. refineries, metallurgical industries and chemical industries) and require a significant amount of energy for the port equipment (e.g. yard tractors, reach stackers and cranes). Several ongoing pilot projects in industrial port districts worldwide demonstrate the interest on hydrogen use in ports. For example, the port of Hamburg and the port of Rotterdam suggest the concept of ports as hydrogen hubs, i.e. an infrastructure which supply hydrogen for both industrial and port users. The use of hydrogen as fuel for cargo handling equipment has also been proposed by the port of Seattle, the port of Los Angeles and the port of Valencia [5]. This study presents a comparison of different solutions for hydrogen-based
decarbonization strategies applied to a typical Mediterranean port. At first, an overview of hydrogen production, transport, conversion, and utilization technologies is presented. A process simulation model developed by the authors in a previous study [6] is then improved and used to analyze and compare the levelized cost of hydrogen and the equivalent carbon emissions of different configurations of the energy systems, where hydrogen is (i) locally produced via RES-driven water-electrolysis, (ii) imported in its pure form via ship/trucks/pipelines, or (iii) imported as energy carrier (e.g. ammonia or LOHC) via ship/truck. The potential decarbonization of port vehicles and industrial hydrogen users is evaluated with reference to the conventional energy supply. For port cargo handling equipment and vehicles, hydrogen as fuel is compared
with the electric vehicles in terms of costs and carbon impact reduction. Preliminary results suggest a levelized cost of local-produced hydrogen of about 9 €/kgH2. Hence, it emerges that, to date, the most mature and convenient way of importing hydrogen is via trucks in liquid or compressed forms (4-5 €/kgH2 [7]). Part of the electricity used for the electrolysis process should be purchased from the grid to meet the port hydrogen demand while maintaining the competitiveness of the hydrogen production system. This,
however, implies that the locally produced hydrogen cannot reach a zerocarbon impact, although the model results show a potential reduction of the equivalent carbon emissions from port equipment of up to 70%
Practical Microarchitectural Attacks from Integrated GPUs
No full textDark silicon is pushing processor vendors to add more specialized units such as accelerators to commodity processor chips. Unfortunately this is done without enough care to security. In this paper we look at the security implications of integrated Graphical Processor Units (GPUs) found in almost all mobile processors. We demonstrate that GPUs, already widely employed to accelerate a variety of benign applications such as image rendering, can also be used to “accelerate” microarchitectural attacks (i.e., making them more effective) on commodity platforms. In particular, we show that an attacker can build all the necessary primitives for performing effective GPU-based microarchitectural attacks and that these primitives are all exposed to the web through standardized browser extensions, allowing side-channel and Rowhammer attacks from JavaScript. These attacks bypass state-of-the-art mitigations and advance existing CPU-based attacks: we show the first end-to-end microarchitectural compromise of a browser running on a mobile phone by orchestrating our GPU primitives. While powerful, these GPU primitives are not easy to implement due to undocumented hardware features. We describe novel reverse engineering techniques for peeking into the previously unknown cache architecture and replacement policy of the Adreno 330, an integrated GPU found in many common mobile platforms. This information is necessary when building shader programs implementing our GPU primitives. We conclude by discussing mitigations against GPU-enabled attackers

Jean Rolin, à la croisée des voies (et des voix) ouvrières : quête, enquête et terrain
No full textL’Organisation (1996), Traverses (1999) et Terminal frigo (2005) de Jean Rolin, véritable trilogie viatique et ouvrière, ramènent l’auteur, ancien maoïste, auprès de « la classe » et proposent des modalités différentes d’investigation d’un territoire social. Ces oeuvres nous permettent de suivre la trajectoire politique, personnelle et littéraire de l’auteur qui va du roman autobiographique, centripète, à la littérature de terrain, centrifuge ; de la quête à l’enquête ; d’une position d’autorité, de surplomb, d’une imposture en somme, à une « participation observante », in situ, qui permet à l’intellectuel d’accepter son étrangement.Jean Rolin’s L’Organisation (1996), Traverses (1999), and Terminal frigo (2005), a veritable journey and working-class trilogy, bring the author, a former Maoist, back to “the class” and propose various methods to investigate a social territory. These works allow us to follow the political, personal, and literary trajectory of the author, moving from the autobiographical, centripetal novel, to the centrifugal field literature ; from the quest to the investigation ; from a position of authority, overhanging, of imposture in fact, to an “observant participation”, in situ, which allows the intellectual acceptance of their strangeness
