A Survey on LoRa for Smart Agriculture: Current Trends and Future Perspectives
2023
This paper provides a survey on the adoption of LoRa in the agricultural field, and reviews state-of-the-art solutions for Smart Agriculture, analyzing the potential of this technology in different infield applications. In particular, we consider four reference scenarios, namely irrigation systems, plantation and crop monitoring, tree monitoring, and livestock monitoring, which exhibit heterogeneous requirements in terms of network bandwidth, density, sensors’ complexity, and energy demand, as well as latency in the decision process. We discuss how LoRa-based solutions can work in these scenarios, analyzing their scalability, interoperability, network architecture, and energy-efficiency. Fi…
Social-Behavioral Aware Optimization of Energy Consumption in Smart Homes
2018
Residential energy consumption is skyrocketing, as residential customers in the U.S. alone used 1.4 trillion kilowatt-hours in 2014 and the consumption is expected to increase in the next years. Previous efforts to limit such consumption have included demand response and smart residential environments. However, recent research has shown that such approaches can actually increase the overall energy consumption due to the numerous complex human psychological processes that take place when interacting with electrical appliances. In this paper we propose a social-behavioral aware framework for energy management in smart residential environments. We envision a smart home where appliances are int…
Equilibrium in a duopoly game with homogeneous adaptive expectations and isoelastic demand
2011
In this paper we consider a non linear discrete time Cournot duopoly game with isoelastic demand and where players have homogeneous adaptive expectations. The evolution of expected outputs over time is generated by the iteration of two-dimensional map and the long-run behavior is characterized by equilibrium points which are locally stable.

Un Modello di Massima Copertura della Domanda per l’Allocazione Ottima delle Ciclostazioni di AMAT
2018
AMAT Palermo S.p.A. is the public transport company of the municipality of Palermo. AMAT manages the bike sharing system and within a sustainable mobility project has involved the DSEAS and four secondary schools to the research project “GoToSchool”, a project whose main aim is to foster the use of the bike by the students in getting to the school.The project developed in two phases: the first phase was devoted to the estimate of the demand of bike sharing service from the students; the second phase was committed to the study of an optimal facility allocation problem in order to maximize the demand of bike sharing service arising from students.The optimization model can be easily customized…
El Contrato De Trabajo En El S. XXI: La Economma Colaborativa, On-Demand Economy, Crowdsorcing, Uber Economy Y Otras Formas De Descentralizaciin Prod…
2015
Spanish Abstract: Las nuevas plataformas virtuales estan cambiando la forma en la que se presta servicios. La tecnologia esta trasformando las organizaciones empresariales de forma que el trabajador subordinado es menos necesario. Un nuevo tipo de empresas --"on demand, economy "sharing economy"-- se dedican a conectar al cliente directamente con el prestador de servicios. De esta forma, estas companias desarrollan su principal actividad a traves de trabajadores autonomos. En este contexto, el Derecho del trabajo se enfrenta a su mayor desafio, teniendo que regular una realidad muy diferente a la existente en el momento en el que fue creado. Sin embargo, los trabajadores siguen necesitando …
Effect of micro-aeration and leachate replacement on COD solubilization and VFA production during mono-digestion of grass-silage in one-stage leach-b…
2010
The effect of micro-aeration and leachate replacement with fresh water on chemical oxygen demand (COD) solubilization and volatile fatty acid (VFA) production during the mono-digestion of grass-silage in one-stage leach-bed reactors (LBRs) was investigated in four LBRs, L0 (control), L1, L2 and L3 in batch mode at 35 + or - 1 degrees Celsius for 57 days. Results showed that leachate replacement without pH adjustment (L3) resulted in 2.7 and 1.3 times more SCOD in the leachate compared to control (L0) or leachate replacement with initial pH adjustment (L1), respectively. Micro-aeration at flow rate of 1 L min(-1) (2.5 L of air) in L2 resulted in 4-fold increase in VFA production (from 2.2 to…
Effect of macro and micro nutrients addition during anaerobic mono-digestion of grass silage in leach-bed reactors
2019
The effect of macro- (NH4Cl) (set I) and micro-nutrients (Fe, Ni, Co and Mo) (set II) addition on chemical oxygen demand (COD) solubilisation during anaerobic mono-digestion of grass silage was investigated in two sets of leach bed reactor experiments at 35°C. Results showed that addition of NH4Cl and micro-nutrients improved COD solubilisation by 18% (0.56 g SCOD g−1 volatile solids) and 7% (0.45 g SCOD g−1 VS), respectively than control. About 20–50% of the added micro-nutrients were bioavailable in the produced leachates, while the rest (50–80%) were adsorbed onto the grass silage. Results of biological methane potential assays showed that, specific methane yields of grass silage were im…
The predicting role of self-efficacyin the Job Demands-Resources Model: A longitudinal study
2012
AbstractTaking Albert Bandura's Social Cognitive Theory as our starting point, we analysed the predicting role of self-efficacy in the Job Demands-Resources Model. We tested longitudinally the two underlying psychological processes, namely: 1) the motivational process, in which job resources (i.e., job autonomy and social support climate) foster engagement, and 2) the erosion process, in which high job demands (i.e., quantitative overload and role conflict) lead to burnout. Structural equation modelling in a sample of 274 secondary-school teachers confirmed both processes, as well as the powerful predicting role of self-efficacy. Finally, we discuss the theoretical findings and the practica…
