Multiple point spaces of finite holomorphic maps

2016

Esta tesis trata sobre espacios múltiples de aplicaciones holomorfas finitas entre variedades complejas. Nuestro enfoque es el de la teoría de singularidades, y las aplicaciones serán consideradas bajo la relación de A-equivalencia, es decir, salvo cambios de coordenadas en partida y llegada. Nos centramos en relacionar propiedades de los espacios de puntos múltiples con propiedades como la A-estabilidad y la A-determinación finita. En generaEl trabajo está organizado de la siguiente manera: El Capítulo 1 contiene los fundamentos básicos necesarios para el resto del trabajo. En el Capítulo 2 definimos los espacios de puntos múltiples de una aplicación. Demostramos que solo hay una manera de…

Uno strumento virtuale per il monitoraggio e il controllo di un impianto fotovoltaico a concentrazione

2014

In questa memoria si presenta una sintesi delle attività condotte nell'ambito del progetto SERPICO ("Sviluppo E Realizzazione di Prototipi di Inverter per impianti fotovoltaici a Concentrazione", PO-FESR Sicilia 2007-2013, Misura 4.1.1.2). Il progetto ha riguardato lo sviluppo di un prototipo di impianto fotovoltaico-termico a concentrazione e del relativo sistema di monitoraggio e controllo. Tale sistema permette di acquisire le quantità sia elettriche che termiche. Inoltre esso implementa un algoritmo per l'inseguimento solare utilizzato per ottimizzare la produzione di potenza.

Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31

2019

Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…

CuInSe2/Zn(S,O,OH) junction by electrochemical and chemical route for photovoltaic applications (GE 2014)

2014

Electrodeposition is a convenient technique for the development of low cost materials for photovoltaic (PV) device processing. Using a single step electrodeposition route, several groups have fabricated CIS (CuInSe) and CIGS (CuInGaSe) films. One of the most important requirements for successful application of one-step electrodeposition film formation is the ability to control composition of the deposited films and to develop polycrystalline microstructures with a low surface roughness and high sintered density.

Photoelectric valuation of highly efficient Dye-Sensitized Solar Cells

2015

Nowadays, a growing demand for free and clean energy requires the study and the development of new low-cost solar photovoltaic (PV) cells. Among them, Dye Sensitized Solar Cells (DSSCs) based on ruthenium complexes as sensitizers are assuming a great importance. The DSSCs under study are composed placing in succession a transparent conductive glass on which is screen-printed a mesoporous TiO2 thin film sensitized by a ruthenium based dye (N719) , an electrolytic solution containing a redox couple (I-/I3-) and another conductive glass covered by a thin transparent catalyst platinum film. In this work, we have measured the main photoelectrochemical parameters of the above mentioned DSSCs at d…

Light Soaking measurements on Ruthenium-based Dye Sensitized Solar Cells

2016

An interesting phenomenon occurring in Dye Sensitized Solar Cells (DSSCs) when exposed to an uninterrupted period of illumination is the so-called light soaking effect, which consists in the increase of the main electrical parameters of the cell, such as the photocurrent and the efficiency. Studying such an effect has noteworthy practical implications, ranging from the optimization of the manufacturing process to stability tests of DSSCs. In this paper, we present an experimental investigation on the performance variation, due to light soaking, of Ruthenium-based DSSCs.

Density of States evaluation of Molybdenum Oxide for c-Si solar cell

Silicon-based heterojunction technology (HJT) is one of the most promising candidates for high performance and low cost solar cells with world-record efficiency close to 27% in IBC architecture. The HJT exploits the excellent passivation properties of hydrogenated amorphous silicon (a-Si:H); although, the use of doped a-Si:H has drawbacks such as parasitic absorption and low-thermal budget to cope with back-end metallization. Replacing the p-type a-Si:H with molybdenum oxide (MoOx) is a viable alternative. Optimizing this hole-selective layer is needed; however information on the defect density of states (DOS), linked to oxygen vacancies is still lacking.

Effatha - mowa i mówienie w księgach Starego i Nowego Testamentu

2016

Szerokie zagadnienie mowy i mówienia w Biblii zostało przedstawione przede wszystkim na dwóch płaszczyznach: historycznej i antropologicznej. W pierwszym przypadku chodziło o prześledzenie semantycznego rozwoju hebrajskich oraz greckich określeń zwią­zanych z szeroko rozumianym procesem komunikacyjnym, w drugim zaś o ukazanie zjawiska mowy z antropologicznego punktu widzenia. Całość obrazu dopełnia odnotowanie zjawiska lingwistycznego opisanego przez autorów tekstów biblijnych. W pojemnym znaczeniowo pojęciu hebrajskiego „qól" zostało ukazane cale spektrum semantyczne, rozciągające się od rzeczownika „dźwięk" do rzeczownika „głos". Ten jeden hebrajski leksem został przetłumaczony przez Grek…
