Multiple Scenario Analysis of Battery Energy Storage System Investment: Measuring Economic and Circular Viability
2022
Circular business models for batteries have been revealed in earlier research to achieve economic viability while reducing total resource consumption of raw materials. The objective of this study is to measure the economic performance of the preferred business model by creating different scenarios comparing second life (spent) and new battery investment for seven different European regions and four energy management strategies. Findings reveal levels of economic ability for a total of 34 scenarios simulated, including direct savings per kWh, a total change in energy costs per year, battery charge/discharge cycles, and comparative breakeven analyses. Regional effects are also measured based …
A dynamic simulation approach to frame drivers and implications of corruption practices on firm performance
2014
Corruption is a multifaceted socio-economic phenomenon widely spread - although with different intensity - all around the world. Many studies on corruption have been conducted at a country-level, but relatively little effort has been placed in evaluating its implications, in terms of both financial and competitive performance, at a firm-level. Therefore, this paper aims at exploring the causal relationships underlying the effect of corruption on firm performance in order to show the different scenarios that may emerge from the combination between external (i.e., contextual conditions) and internal (i.e., organizational characteristics) forces that drive corruption. To this end, we adopt a D…
UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey
2021
Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…
Scenario modeling for the management of international bond portfolios
1998
We address the problem of portfolio management in the international bond markets. Interest rate risk in the local market, exchange rate volatility across markets, and decisions for hedging currency risk are integral parts of this problem. The paper develops a stochastic programming optimization model for integrating these decisions in a common framework. Monte Carlo simulation procedures, calibrated using historical observations of volatility and correlation data, generate jointly scenarios of interest and exchange rates. The decision maker's risk tolerance is incorporated through a utility function, and additional views on market outlook can also be incorporated in the form of user specifi…
A multidimensional model based on the Choquet integral to evaluate performance of waterfront redevelopment projects in promoting local growth
2012
The paper aim to construct a multi-criteria model assessing the suitability of waterfront development scenarios to contribute to local growth. The model applies to the city of Catania. It is built according to the strategic directions on territorial government recognized by European Community for Sicily. The evaluation model includes a set of strategic criteria for local social and economic sustainability. The aesthetic and functional regeneration of urban waterfront areas is a very complex issue because of the manifold social, environmental and economic implications. The choice among different alternatives of redevelopment of such a kind of areas should be addressed with typical techniques…
Uncertainty Analysis in the Evaluation of the DDF Curves Parameters in Climate Change Scenarios
2016
Abstract On the global scale, there is a robust observational evidence that, over the last decades, the frequency and intensity of extreme events significantly changed, even if regional and local studies have highlighted complex and non-uniform spatial patterns. Climate change can cause increased rainfall intensities which leads to an additional impact on drainage systems, due to the alteration of magnitude and frequency of peak flows over their service life. For this reason, the design criteria of urban drainage infrastructures need to be revised and updated, in order to take into account the possible variations of extreme rainfall. In particular, the Depth-Duration-Frequency (DDF) curves,…
El cuerpo materno en la red: entre el orden de lo ?deseable? y el de lo real
2019
El estilo de vida fitness se realiza en, y a través de, un entramado subjetivo y de poder en el que circulan y se ensamblan dispositivos empresariales, terapéuticos, sanitarios y de espectacularización de los cuerpos, tendientes a inscribir la vida de la población en las tramas conflictivas de un capitalismo heterosexista, neoliberal e informacional. En dicho marco, la temporalidad, metamorfosis y plasticidad del cuerpo materno irrumpe como problema y objeto de intervención de tecnologías diversas orientadas a ajustar su tamaño, forma y devenir a los parámetros de la vida activa y saludable. En escenarios digitales, dicha tensión se materializa, por un lado, a través de dispositivos visuale…
ARCHITETTURA/INFRASTRUTTURA. Tessuti urbani e nuovi paesaggi
2013
Attraverso il materiale raccolto in questo volume, si vuole contribuire all’ordinamento e alla sistematizzazione degli apporti critici e degli apparati documentali intorno alla tematica che indaga il rapporto tra architettura e opera infrastrutturale. La sempre maggiore necessità di una verifica e messa a punto di strategie capaci di creare le basi migliori per determinare una sintesi operativa sulle questioni che derivano dalle trasformazioni che l’opera infrastrutturale determina all’interno dei nostri territori, urbani e naturali, si ritiene debba anche passare da un esame che proviene dal dibattito disciplinare e dall’esperienze sul campo, quest’ultima attraverso lo studio di opere e pr…
Opportunità attive: Palermo mia
2014
Le questioni poste nel saggio portano a considerare la dinamica contemporanea come il luogo d’elaborazione di un concetto interpretativo dell’architettura, intesa come servizio/funzione nei confronti delle mutevoli necessità dell’utenza, elemento di indirizzo strategico nella individuazione di proposte anche sostenibili. Un pretesto, questo, per parlare del progetto e spingersi oltre, anche solo di poco nel luogo ‘rassicurante’ depositario dell’identità, delle abitudini e delle emozioni negli “Interni” del nostro quotidiano.
STUDY REGARDING THE MARKOWITZ MODEL OF PORTFOLIO SELECTION
2015
The Markowitz model was introduced through the work of Harry Markowitz (1952) and analyzes the risk and the rentability of a diversified portfolio of securities. In our research, we want to use the Markowitz model in order to identify the structure of the optimal portfolio of risky assets, in other words the efficient portofolio. The study, conducted on three romanian companies from the construction sector, listed on the Bucharest Stock Exchange, leads to the conclusion that the portfolio is illegitimate, so it is necessary to sell the securities of the companies in the absence, procedure known as short sell.
