Efficient distributed load balancing for parallel algorithms
(Universita degli studi di Salerno, 2011-04-29)With the advent of massive parallel processing technology, exploiting the power offered by hundreds, or even thousands of processors is all but a trivial task. Computing by using multi-processor, multi-core or many-core ... -
Electical properties of pure and Co-substituted ZnO thin films investigated by UV-assisted SPM experiments
(Universita degli studi di Salerno, 2018-06-28)ZnO is an intrinsic n-type, wide band-gap (3.4 eV at 0 K), semiconductor which has been attracted the interest of the scientific community for several decades. More recently, ZnO has caught a renewed interest due to the ... -
Electric transport properties of S/F hybrids: weak and inhomogenous ferromagnet
(Universita degli studi di Salerno, 2012-03-30)Superconductivity (S) and ferromagnetism (F) are competing phases whose coexistence is unlikely to occur. Exceptions require a non−uniform profile both for the pairing and the magnetization, as in the case of the FFLO state ... -
Electrical and thermal transport properties of superconducting materials relevant for applications
(Universita degli studi di Salerno, 2018-07-06)Superconducting materials are used in several applications among which the large-scale ones take advantage of the high energy transport capabilities of superconductors due to the low losses in electrical conduction. From ... -
Electron-electron and electron-phonon interactions in strongly correlated systems
(Universita degli studi di Salerno, 2013-04-29)In this work we investigate some aspects of the physics of strongly correlated systems by taking into account both electron-electron and electron-phonon interactions as basic mechanisms for reproducing electronic correlations ... -
Elliptic Operators with Unbounded Coefficients
(Universita degli studi di Salerno, 2017-04-28)Aim of this manuscript is to give generation results and some Hardy inequalities concerning elliptic operators with unbounded coefficients of the form Au = div(aDu) + F ·Du + V u where V is a real valued function, a(x) = ... -
Elucidation of crystal structures and structural changes using X-ray powder diffraction
(Universita degli studi di Salerno, 2021-03-12)In the process of understanding the properties and behaviour of a compound, and designing improved materials, probing the atomic-level structure is a decisive step. Single crystal X-ray diffraction, a widespread, non-destructive ... -
Enantioselective construction of new heterocyclic scaffolds via organocatalyzed cascade reactions
(Universita degli studi di Salerno, 2019-02-04)Chirality plays a vital role in human daily life. After the famous but tragic case regarding the Thalidomide, Food and Drug Administration (FDA) gave a guide in relation to the submission of new drug applications... [edited ... -
Environmental and catalytic applications of alkaline oxides
(Universita degli studi di Salerno, 2015-04-20)Alkaline oxides are widely used in industrial processes involving removal of gaseous compounds as unwanted by-products such as CO2, hydrogen sulphide and nitric oxides. Traditional processes generally involve Ca-based ... -
Enzymatic synthesis of macrolactones
(Universita degli studi di Salerno, 2011-02-24)Macrolactones are a large and structurally diverse class of compounds. Natural products having a macrolactone structure have been isolated from many natural sources such as plants, insects, marine organism and bacteria. ... -
Estimates for the transition kernel for elliptic operators with unbounded coefficients
(Universita degli studi di Salerno, 2023-02-09)This manuscript is devoted to the study of the qualitative behaviour of the solutions of evolution equations arising from elliptic and parabolic problems on unbounded domains with unbounded coefficients. In particular, we ... -
Event triggering and deep learning for particle identification in KM3NeT
(Universita degli studi di Salerno, 2018-04-11)Neutrino astronomy experiments like KM3NeT allow to survey the Universe leveraging the properties of neutrinos of being electrically neutral and weakly interacting particles, making them a suitable messenger. Observing ... -
