The Covid-19 pandemic and the measures that have been adopted to try and contain it have had a deep impact on the Italian economy, the scope of which cannot be perfectly gauged as yet. The consequences of Covid-19 crisis have affected Italian enterprises’ operating in different sectors. Most of enterprises have been obliged to change their technical ways. Thus, new specific trends and actions have been adopted during this challenging period.

The World

Introduction. The situation in the global economy and business during the COVID-19 pandemic is analyzed in this article. More than 30 million people worldwide have already been infected with the coronavirus, which came from China. However, the spread of the disease has also had an extremely serious impact on the economies of various countries in the world. The Organization for Economic Co-operation and Development has already said that it will take many years for the world to recover from the pandemic. EU GDP in the second quarter of 2020 showed a record decline - 14.4% year on year. The German economy returned to the level of 2011, the Spanish - in 2002, and the Italian economy was rejected in the early 1990s. These and other characteristics show the importance of research on this topic and problem, because it does not apply to a particular region or a particular country, but the whole world.

Hybrid Rockets

Ablative-cooled hybrid rockets could potentially combine a similar versatility of a liquid propulsion system with a much simplified architecture. These characteristics make this kind of propulsion attractive, among others, for applications such as satellites and upper stages. In this paper, the use of hybrid rockets for those situations is reviewed. It is shown that, for a competitive implementation, several challenges need to be addressed, which are not the general ones often discussed in the hybrid literature. In particular, the optimal thrust to burning time ratio, which is often relatively low in liquid engines, has a deep impact on the grain geometry, that, in turn, must comply some constrains. The regression rate sometime needs to be tailored in order to avoid unreasonable grain shapes, with the consequence that the dimensional trends start to follow some sort of counter-intuitive behavior. The length to diameter ratio of the hybrid combustion chamber imposes some packaging issues in order to compact the whole propulsion system. Finally, the heat soak-back during long off phases between multiple burns could compromise the integrity of the case and of the solid fuel. Therefore, if the advantages of hybrid propulsion are to be exploited, the aspects mentioned in this paper shall be carefully considered and properly faced.

Power Pulse

Flip-flop is an important unit in digital integrated circuits, whose characteristics have a deep impact on the performance of the circuits. To reduce the power dissipation of flip-flops, clock triggering edge control technique is proposed, which is feasible to block one or two triggering edges of a clock cycle if they are redundant in dual-edge pulse-triggered flip-flops (DEPFFs). Based on this technique, redundant pulses can be suppressed when the input stays unchanged, and all the redundant triggerings are eliminated to reduce redundant transitions at the internal nodes of the flip-flop, so the power dissipation can be decreased. Then a novel DEPFF based on clock triggering edge control (DEPFF-CEC) technique is proposed. Based on the SMIC 65-nm technology, the post layout simulation results show that the proposed DEPFF-CEC gains an improvement of 8.03–39.83% in terms of power dissipation when the input switching activity is 10%, as compared with its counterparts. Thus, it is suitable for energy-efficient designs whose input data switching activity is low.

The Impact

AbstractThe objective of this paper is twofold: firstly, it analyzes the evolution of frauds in the Italian wine value chain over the period 2007–2015, and then, using a properly disaggregated social accounting matrix (SAM) of the Italian economy, it simulates the impact of wine frauds on the national economy in terms of growth, employment, value added and income. The wine industry is the sector most exposed to frauds within the Italian agro-food system accounting for 88% of total value of seized agro-food outputs. Most irregularities (95%) are made by only three agents, specifically individual wineries, bottlers-wholesalers and retailers. We estimated industry-specific SAM multipliers to assess the share of the Italian economy depending on irregular wine production. These activities account for 11.5% of specialized permanent crop farms output and over 25% of wine industry output. This is a sign of vulnerability of the wine industry: should a food scandal/scare determine a drop in consumers’ demand, the negative effect on production activities of these sectors may be large. The SAM was also used to perform an impact analysis adopting a counterfactual approach. Results show a slightly positive increase of value added (6 million euro) along with an overall decrease in the activity level (an output loss of 406 million euro and more than six thousand full time jobs lost). This contractionary effect can be explained with fraud rents. Indeed, the extra-profits from frauds do not activate the economy circular flow as most of them leak out to exogenous accounts such as the public administration and the rest of the world.
