A subspace based fault diagnose method and its application on mechatronics systems
2014
The mechatronics systems are widely used in modern society. This paper presents a novel data-driven scheme which can be used for fault diagnose of mechatronics systems. The proposed method is based on the subspace identification of parity vector. By constructing the output observer, critical variables can be acquired by soft sensors. This makes the fault diagnoses free from the limitation of online measurement. A diagnose observer is designed directly from the parity vector. Finally, the proposed scheme is tested by the Simulink benchmark of vehicle suspension and shows its good performance.
Post Feed-in Scheme Photovoltaic System Feasibility Evaluation in Italy: Sicilian Case Studies
2014
: Thanks to national energy policies, over recent years the Italian photovoltaic (PV) sector has undergone an extraordinary growth, also affecting the primary sector. In this context, Mediterranean greenhouses are well-adapted to photovoltaic systems because they represent one of the most energy-intensive sectors in agriculture. The Italian feed-in scheme ended at the beginning of 2013, making it necessary to investigate the feasibility of photovoltaic systems devoid of any electricity production-related incentives. In this paper, production cost and profitability analyses of photovoltaic electricity have been conducted, considering Mediterranean solar greenhouses in which, thanks to net me…
The Euro-Dollar Exchange Rate: Is it Fundamental?
2002
In this paper we have applied two approaches to the study of the dollar real exchange rate in relation with the Euro-area currencies. First, using dynamic panel techniques, we estimate an error correction model for the dollar real exchange rate versus seven developed countries, four of them Euro-area members. Second, we aggregate the European variables and estimate a model for the Euro-dollar real exchange rate using time series techniques. After identification and model selection, the same specification can be adopted in the two cases, in an eclectic model including real interest rate and productivity differentials, together with relative fiscal policy and net foreign asset positions. This…
The Euro-Mediterranean Partnership and Financial Integration: a first assessment for selected countries
2009
In this paper, we try to provide a first assessment on the extent of financial integration and convergence between selected European and Southern Mediterranean countries involved in the Barcelona process. In particular, we implement a simple test of capital mobility based on the verification of the international real interest parity hypothesis between domestic rates against the real rate of Germany, used as the European reference country, and against the real rate of the US. We repeat the test before and after the introduction of the Euro, and then measure the speed of real interest rate convergence.
Leading the way toward fuel parity in photovoltaics: The utility-scale market in Sicily, Italy
2016
The global photovoltaic (PV) market has been growing exponentially since almost twenty years. This huge demand for photovoltaic systems has been mainly driven by public subsidies in the form of a variet y of national incentive schemes. However, in Countries where successful incentive schemes have been pioneered and are now – as planned - being brought to an end, the PV market is called to the challenge of surviving without any incentive to the end user. Grid and fuel-parity represent the keystone of this emerging new phase in the history of this renewable energy technology. In this paper we present a sensitivity analysis showing that in Sicily, Italy, the Levelized Cost of Energy from utili…
Reversal of Gender Disparity in Journalism Education- Study of Ghana Institute of Journalism
2017
Journalism has practically become a feminine profession across the world. To understand the root of the flow of women into the Journalism profession it is pertinent to begin at the university education level. Gallagher’s 1992 worldwide survey of female students in 83 journalism institutions reveals a significant increase in number of female students. Djerf-Pierre (2007) and others argue along Bourdieu’s conception of education as a form of social capital which empowers, enables and enhances women’s competitiveness in a pre-dominantly androgynous social arena. The study analyses 16 years of enrolment data of the Academic Affairs Unit of the Ghana Institute of Journalism (GIJ), a leading Jour…
Load mismatch of grid-connected photovoltaic systems: Review of the effects and analysis in an urban context
2013
Abstract The mismatch between generated and consumed electricity is a relevant topic of the energy and economic assessment of photovoltaic (PV) systems. Due to the load mismatch some amount of PV electricity may be exported to the grid because the electrical demand is temporarily lower than production, whereas a consumption, which is higher than production and/or that does not match the available PV generation, will require to be supplemented by the public grid electricity. The presence of the load mismatch can cause the effect of disadvantageously purchasing electricity from the grid and/or squandering the unexploited PV energy. If only a very small part of the PV generation is used to sup…
Measurement of CP asymmetry in D 0 → K - K + and D 0 → π - πdecays
2014
Time-integrated $CP$ asymmetries in $D^0$ decays to the final states $K^- K^+$ and $\pi^- \pi^+$ are measured using proton-proton collisions corresponding to $3\mathrm{\,fb}^{-1}$ of integrated luminosity collected at centre-of-mass energies of $7\mathrm{\,Te\kern -0.1em V}$ and $8\mathrm{\,Te\kern -0.1em V}$. The $D^0$ mesons are produced in semileptonic $b$-hadron decays, where the charge of the accompanying muon is used to determine the initial flavour of the charm meson. The difference in $CP$ asymmetries between the two final states is measured to be \begin{align} \Delta A_{CP} = A_{CP}(K^-K^+)-A_{CP}(\pi^-\pi^+) = (+0.14 \pm 0.16\mathrm{\,(stat)} \pm 0.08\mathrm{\,(syst)})\% \ . \nonu…

Exchange Rate and Interest-Rate Driven Competitive Advantages in the EMU
2002
Real exchange and interest rates may still fluctuate inside the EMU and give rise to changes in competitiveness. We find, in contrast to what is generally expected, no convergence in these variables after the introduction of the euro. On the contrary, a divergence is found that is extraordinary when compared to the preceding 40 years. The magnitude of the divergence should urge on a wave of restructuring in the EMU, conditioned upon adequate policy responses. The worst-case scenario involves a flight to structural support and protectionism, challenging the whole idea of the EMU.
