Für die Steigerung der Qualität, Effizienz und Ausbeute bei der Herstellung moderner elektronischer und optoelektronischer Bauelemente aus GaN ist die Verfügbarkeit von defektarmen GaN-Schichten wichtig. Moderne Methoden zur Erzeugung defektarmer Schichten auf Fremdsubstraten stoßen an ihre Grenzen, die durch die große Fehlanpassung zwischen Fremdsubstrat und GaN gegeben sind. Ein Ausweg ist das Wachstum auf GaN-Substraten (Homoepitaxie). Deshalb sollen in dieser Arbeit mögliche Wege und Prozesse untersucht werden, um freistehende GaN-Substrate zu erzeugen. ····· 10361170004

Ultrashort laser pulses are applied to prepare vibrational wave packets on the molecules. Their dynamics is investigated via the pump-probe method. The priniples of classical and quantum mechanical coherence are introduced in the first chapters together with the concepts of wave packet focusing and fractional revivals. Those are used to deduce the vibrational and electronic decoherence of molecular wave packets in the rare gas host. A novel coherent control scheme based on chirped laser pulse excitation is worked out to manipulate the wave packets. Furthermore, the molecular energy relaxation and the rotational behaviour in the rare gas host are discussed. Apart from the molecular wave packets, coherent phonons of the rare gas crystal are investigated via the pump-probe spectroscopy on the molecule. Those phonons are excited impulsively in a molecular electronic transition and modulate the host density close to the molecule. Due to the special probe situation, only coherent zone boundary phonons show up in the transients. ····· 10361158104

En el modelo de una temperatura se considera la absorción volumétrica de un pulso rectangular de radiación láser en una muestra sólida de dimensiones finitas. Se analizaron los casos de aislamiento adiabático y el de contacto isotérmico. Se obtuvieron los criterios de absorción de luz superficial y volumétrica. En el modelo de dos temperaturas se obtiene la distribución de temperatura para el subsistema de electrones y de fonones en películas delgadas y muestras masiva. Este modelo muestra que la difusión térmica es el principal mecanismo de relajación de energía en el subsistema de fonones. Se muestra que el mecanismo depende de la correlación entre la longitud de la muestra y la longitud de enfriamiento de los electrones. Para estos modelos de temperatura se realizó la modelación numérica, así como el análisis de la distribución de temperatura para pulsos cortos y largos, así mismo para películas delgadas y masivas se analizaron las diferentes correlaciones entre la duración del pulso láser y los tiempos característicos. ····· 10361137003

The remaining is dark energy with a strange and unique feature: it repels. Many cosmologists, though, are now leaning toward a different idea, known as quintessence. The dynamism is what cosmologists find so appealing about quintessence. While vacuum energy is completely inert, the quintessence interacts with matter and evolves with time, so it might naturally adjust itself to reach the observed value today. Recent observations have shown that the Universe is not only expanding, but it is accelerating. Due to cosmic expansion and curvature of space-time, observing distanced objects becomes difficult. For constraining the parameters that describe the Universe one needs measurements obtained independently of the cosmological model: angular diameter, luminosity distance, the Hubble parameter at different redshifts and the first acoustic peak from the power spectrum of the cosmic microwave background. Data will be fitted to test the quintessence model and hopefully to answer the question: What kind of Universe do we live in ····· 1036191613

La intuición básica de Einstein fue postular que en un punto concreto no se puede distinguir experimentalmente entre un cuerpo acelerado uniformemente y un campo gravitatorio uniforme. Desde que Einstein propuso su teoría en 1916 hasta el 2007, solo se tenían 4 formulaciones lagrangianas para relatividad general, a saber Einstein-Hilbert, Hilbert- Palatini, Capovilla-Dell-Jacobson (CDJ) y Pleba ski, las cuales discutiremos ampliamente en este trabajo.

In this thesis, we use various approaches and techniques to investigate different aspects of this interaction, and compare our models to observations. We start with a semi-empirical analysis of post-CE systems to predict the outcome of a CE interaction. Using detailed stellar evolutionary models, we revise the a equation and calculate the ejection efficiency, a, both from observations and simulations consistently. We find a possible anti-correlation between a and the secondary-toprimary mass ratio, suggesting that the response of the donor star might be important for the envelope ejection. Secondly, we present a survey of three-dimensional hydrodynamical simulations of the CE evolution using two different numerical techniques, and find very good agreement overall. However, most of the envelope of the donor is still bound at the end of the simulations and the final orbital separations are larger than the ones of young observed post-CE systems. Despite these two investigations, questions remain about the nature of the extra mechanism required to eject the envelope. In order to study the dynamical response of the donor, we perform one-dimensional stellar evolution simulations of stars evolving with mass loss rates from 10-3 up to a few M /yr. For mass-losing giant stars, the evolution is dynamical and not adiabatic, and we find no significant radius increase in any case. Finally, we investigate whether the substellar companions recently observed in close orbits around evolved stars could have survived the CE interaction, and whether they might have been more massive prior to their engulfment. Using an analytical prescription for the disruption of gravitationally bound objects by ram pressure stripping, we find that the Earth-mass planets around KIC 05807616 could be the remnants of a Jovian-mass planet, and that the other substellar objects are unlikely to have lost significant mass during the CE interaction. ····· 10361107859

This book focuses on charm production in the neutrino interactions. The analysis reported in this book is based on data collected by the CHORUS collaboration. Most of the data on charmed particle production by neutrinos has been obtained using large neutrino detectors. Usually the decay of a charmed particle is not seen directly, its presence is inferred from the observation of strange particles or final state leptons. This requires large background subtractions. Major advantages of emulsion techniques used in the CHORUS experiment are the ability to fully reconstruct event kinematics. This suppresses the large background that comes from the decays of kaons and pions. On the other hand there is a disadvantage: low statistics due to scanning load. The improvements in scanning systems and methods which have been done in the CHORUS collaboration, solved this problem.

In this book the Universe is considered as `Anisotropic Universe` and how the different Dark Energy models can dominate it to speed up the expansion has been explained thoroughly with the support of some geometrical parameters and 2D, 3D figures. ····· 1036188055
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In this thesis, I study hydrodynamical models of slim accretion disks - advective, optically thick disks which generalize the standard models of radiatively efficient thin disks to all accretion rates. I start with a general introduction to the theory of accretion onto compact objects. It is followed by a derivation of the commonly-used standard models of thin disks. In the subsequent section I introduce the equations describing slim disks, explain the numerical methods I used to solve them and discuss properties of such solutions. I also give a general derivation of non-stationary equations and present the time evolution of thermally unstable accretion disks. I introduce a state-of-the-art approach coupling the radial and vertical structures of an advective accretion disk and discuss the improvements it brings to vertically-averaged solutions. I also present a numerical model of self-illuminated slim accretion disks. Finally, I present and discuss applications of slim accretion disks. ····· 10361115324
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Mareogramas de distintos puertos de la zona del Estrecho de Gibraltar muestran episodios de oscilaciones de corto periodo (minutos a decenas de minutos) que pueden persistir durante varios días. Estos episodios se registran a lo largo del año aunque, tanto la amplitud como la duración, presenta una distribución temporal con una clara desviación hacia los meses de verano. Las frecuencias de estas oscilaciones son características de los lugares en que se han medido, observándose una respuesta más selectiva en Tarifa que en Ceuta y Algeciras. Se prueba mediante la aplicación de un modelo numérico que estas frecuencias son resonancias de los puertos excitadas a su vez por modos normales de la región del Estrecho de Gibraltar (dominio regional). Perturbaciones atmosféricas pseudo periódicas de alta frecuencia, propagándose por el dominio, pueden generar una amplificación importante en el interior de los puertos, con ganancias modeladas entre 5 y 10. Por tanto, se subraya como el acoplamiento de la dinámica del Estrecho con las estructuras de los puertos cobra importancia por realizarse con relativa frecuencia en condiciones casi resonantes de los dos dominios: Estrecho y puertos. ····· 10361117430
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Dynamic Universe model is based on hard observed facts and does NOT depend on speculation. In this fourth book the simulations predicted the existnce of the large number of Blue shifted Galaxies, in an expanding universe, in 2004 itself. It was confirmed by by Hubble Space Teliscope (HST) observations in the year 2009. This prediction process is clearly shown in the output pictures formed from this Model from old and new simulations. These pictures depict the three dimensional orbit formations. An orbit formation means some Galaxies are coming near (Blue shifted) and some are going away (Red shifted). This book goes on two main lines. First is the main line of thinking, to show mathematically that there will be lots and lots of blue shifted Galaxies mathematically. To support this concept the question what are the possible blue shifted Galaxies is answered further. We find that quasars are blue shifted galaxies. The second line of thinking goes with this finding, that the Quasars are blue shifted galaxies.Forrest Noble (Pan Theory) in his foreword said over 7,000 blueshifted galaxies have been discovered extending beyond the Local Group, first predicted by Mr.Gupta. ····· 1036118979
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Solid state gas sensors have proved to be verypromising for monitoring the emission of airpollutant and toxic gases because they are a low cost element. Titanium dioxide (TiO2) is metal oxide semiconductor.TiO2 has been extensively studied owing to its wide range of applications which include photo catalysis, heterogeneous catalysis, energy storage,solar cell components, corrosion-protective coatings,optical coatings and gas sensing.The objectives of this project was to study the structural, electrical and gas sensing properties of undoped and doped TiO2 thick films.Gas sensing properties of the films werestudied in static gas sensing system by exposing the films to the different gases as CO2, H2S, NH3,Ethanol, LPG and NO2 at different operating temperatures. The optimum operating temperature,sensitivity, selectivity, response, recovery time and the active region of detected gas were determined.Results showed that the doping alters the orientation of microstructure, grain size, composition, electrical and gas sensing characteristics.TiO2 films were observed to be most sensitive to reducing gases than oxidizing gases. ····· 10361118615
