Wavelet analysis and HHG in nanorings Their applications in logic gates and memory mass devices

We study the application of one nanoring driven by a laser field in different states of polarization in logic circuits. In particular we show that assigning boolean values to different state of the incident laser field and to the emitted signals, we can create logic gates such as OR, XOR and AND. We also show the possibility to make logic circuits such as half-adder and full-adder using one and two nanoring respectively. Using two nanorings we made the Toffoli gate. Finally we use the final angular momentum acquired by the electron to store information and hence show the possibility to use an array of nanorings as a mass memory device

Momentum partition between constituents of exotic atoms during laser induced tunneling ionization

The tunneling ionization of exotic atoms such as muonic hydrogen, muonium and positronium in a strong laser field of circular polarization is investigated taking into account the impact of the motion of the center of mass on the the tunneling ionization dynamics. The momentum partition between the ionization products is deduced. The effect of the center of mass motion for the momentum distribution of the ionization components is determined. The effect scales with the ratio of the electron (muon) to the atomic core masses and is nonnegligible for exotic atoms, while being insignificant for common atoms. It is shown that the electron (muon) momentum shift during the under-the-barrier motion due to the magnetically induced Lorentz force has a significant impact on the momentum distribution of the atomic core and depends on the ratio of the electron to the atomic core masses

Reforming Beauty: The Casa delle Zitelle and Female Asylums in Early Modern Venice

This thesis examines the Casa delle Zitelle (the House of Unmarried Girls), a female asylum created to care for poor, beautiful young girls who were at risk of becoming prostitutes in early modern Venice. The institution was founded, as well as funded and administered, by a group of pious patrician women in 1559. The Casa delle Zitelle was not only sponsored by and for women, but also the predominant patrons of the institution were Venetian women. The institution’s commitment to transform the zitelle (unmarried girls) into the sixteenth century ideal of womanhood was best articulated in the design of the architectural complex, which was influenced and patronized by the founding female administrators of the institution. The ability to reform the zitelle also persisted in the devotional imagery of the Zitelle’s attached church, Santa Maria della Presentazione delle Zitelle. This thesis focuses specifically on the altarpiece commissioned by Elisabetta Foppa, The Agony in the Garden (c. 1618) by Jacopo Palma il Giovane, which assisted the zitelle in matters of religion and piety that were instrumental to the girls’ transformations. An examination of Foppa’s altarpiece further reveals an understanding of, and contributes to, an interpretation of the iconographic trends in the visual arts located in the churches of early modern female asylums

Electrons on a spherical surface: Physical properties and hollow spherical clusters

We discuss thephysical properties of a non interacting electron gas constrained to a spherical surface. In particular we consider its chemical potentials, its ionization potential,and its electric static polarizability. All these properties are discussed analytically as functions of the number N of electrons. The trends obtained with increasing N are compared with those of the corresponding properties experimentally measured or theoretically evaluated for quasi spherical hollow atomic and molecular clusters. Most of the properties investigated display similar trends, characterized by a prominence of shell effects. This leads to the de\ufb01nition of a scale-invariant distribution of magic numbers which follows a power law with critical exponent 120.5. We conclude that our completely mechanistic and analytically tractable model can be useful for the analysis of self-assembling complex systems

Modeling and control of advanced powertrain systems and Waste Heat Recovery technologies for the reduction of CO2 emissions in light-duty vehicles

2014 - 2015Transportation is the major sector in the EU where greenhouse gas emissions are still rising. Therefore, in the recent years, the OEMs research and development has focused on the reduction of carbon dioxide (CO2) and pollutants emissions. On the other hand, the European Commission proposed targets for the further reduction of CO2 emissions from new cars by 2020. In this scenario, concepts such as the engines downsizing and other advanced technologies as well as more costly hybrid solutions and, more recently, waste heat recovery (WHR) systems have been proposed...
