Aerobic granular sludge treating high strength citrus wastewater: Analysis of pH and organic loading rate effect on kinetics, performance and stabili…
2017
Abstract In the present paper, the feasibility of citrus wastewater treatment with aerobic granular sludge sequencing batch reactors (AGSBR) was investigated. Two AGSBRs (named R1 and R2, respectively) were operated for 90 days under different organic loading rates (OLR) and pH in two experimental periods. The OLR ranged approximately between 3.0 kg TCOD m−3d−1 and 7 kg TCOD m−3d−1 during Period I, whereas between 7 kg TCOD m−3d−1 and 15 kg TCOD m−3d−1 during Period II. pH was maintained at 7.0 and 5.5 in R1 and R2, respectively. The results revealed that under high OLR and unbalanced feast/famine regime (Period I), the development of fast-growing microorganisms (fungi and filamentous bacte…
Organised Crime and the Economy: a Framework for Policy Prescriptions
2014
In this paper we discuss policies to combat organised crime from the perspective of economic analysis. We introduce concepts such as supply and demand for Mafia and the implied notion of equilibrium to build a framework to classify the contexts in which organised crime interferes with the economy. We then use this framework to discuss policy interventions, distinguishing between policies implemented by the State and mobilisation of civil society. We show that using the economic approach helps understand the aspect of persistence of criminal organisations and identify vicious circles of different nature. The broad spectrum of State policies identified includes norms on competition, on the ef…

Energy saving in airports by trigeneration. Part I: Assessing economic and technical potential
2006
Airports are very energy-intensive areas, because of the large buildings (both terminals and non-passengers areas) equipped with heating and air-conditioning systems, the high power demand for lighting and electric equipment and the energy requests from many facilities within the airport area. The contemporaneous and high demand for power and heat makes cogeneration to represent a viable solution for energy saving; in southern climate zones, however, combined heating, cooling and power (CHCP) systems can lead to even better results. This paper constitutes the first part of a work in two parts; starting from an analysis of typical energy demand profiles in airports, economical and technical …
Market Must Be Defended: The Role of Counter-Espionage Policy in Maximizing Domestic Market Welfare
2020
Countering economic espionage is becoming one of the priorities of the governments of advanced economies. The present paper takes a step forward in the theoretical analysis of the interaction between economic espionage and counter-espionage by focusing on the case of a market opened to international trade. This analysis represents a first approximation to an inquiry into the rationale for the influence of the market level of competition on the dynamics of such interaction. The results suggest that this influence is complex in the case of the effort exerted in economic espionage and the characteristics of market demand play an important role in it. In the case of the counter-espionage policy…
Theoretical and Analytical Framework
2021
Analytically, the present work relies on two foundations, Anthony Downs’ (1957) Proximity model of electoral competition which states that political parties or candidates will seek to position themselves as close as possible to the (preferred) policy positions of voters and Ian Budge’s past election model (1994), according to which parties and candidates use the results of past elections in order to gain information about the electorate landscape. Both models rely on a ‘marketplace’ analogy with demand and supply. Candidates, parties, and politicians supply policies (advertised as policy positions), while the electorate, voters, and constituencies demand policies. Just like in a marketplace…
A new low cost power line communication solution for smart grid monitoring and management
2018
Modern smart grids require the improvement of measurement and communication infrastructures of distribution networks, at both medium voltage (MV) and low voltage (LV) levels. Distributed sensing and measurement systems are needed to provide all necessary data for grid monitoring, control and management, as well as for the implementation of a number of smart functionalities, such as remote control of distributed generators (DGs), real time analysis of power flows, automatic meter reading (AMR), demand side management (DSM), grid automation and so on [1]-[6]. Acquired network data include typical electrical network quantities and status variables (such as powers, voltages, currents, switches …
Effect of Demand Side Management on the Operation of PV-Integrated Distribution Systems
2020
In this new era of high electrical energy dependency, electrical energy must be abundant and reliable, thus smart grids are conducted to deliver load demands. Hence, smart grids are implemented alongside distributed generation of renewable energies to increase the reliability and controllability of the grid, but, with the very volatile nature of the Distributed Generation (DG), Demand Side Management (DSM) helps monitor and control the load shape of the consumed power. The interaction of DSM with the grid provides a wide range of mutual benefits to the user, the utility and the market. DSM methodologies such as Conservation Voltage Reduction (CVR) and Direct Load Control (DLC) collaborate i…
A Novel Priority-Based Ambulance-to-Traffic Light Communication for Delay Reduction in Emergency Rescue Operations
2019
Rescue operations are very critical and sensitive. Only one-second delay could make a serious difference between life and death. Therefore, the delay in rescue operations must be reduced as much as possible. The siren signal can be used to warn other vehicles nearby the ambulance. However, it has no impact on the traffic lights, which is normally a main cause of delay in rescue operations. For this reason, many ambulances get stuck and experience long delay at the intersections, which should not happen by any means. To enhance the rescue operations, this paper proposes a novel Priority-based Ambulance-to-Traffic Light Communication (PATCom). PATCom allows information exchanging between traf…
A decentralized load control architecture for smart energy consumption in small islands
2020
Abstract In this paper we propose the adoption of Overgrid, a new decentralized load control architecture, for balancing the energy production variations introduced with the adoption of renewable sources, facilitating and improving the smart energy retrofit. The system is presented and applied for managing the aggregated daily load profile of a community of domestic end-users in the island of Lampedusa, Italy, exploiting the load profiles gathered in a real measurement campaign. The Overgrid Demand Response (DR) architecture is used for managing the residential flexible loads, estimating the aggregated power demand without any centralized server and creating a virtual “community” of smart b…
