für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The phenomenology of the violation of the CP symmetry by the fundamental interactions is a fascinating subject which, even after decades of dedicated theoretical and experimental research, is far to be fully understood. While investigations of the K and B systems have and will continue to play a central role in this field of research, in depth examinations of the D mesons sector have yet to be performed with enough precision, leaving a gap in our knowledge. This book describes a search for CP violation in Cabibbo-suppressed neutral D decays to two charged pions or kaons performed using the proton-antiproton collisions recorded at the Fermilab`s TeVatron collider by the CDF experiment during February 2002 and January 2010. The result is the current most accurate determination of CP-violating asymmetries in these decays and represents a pioneering measurement of high precision CP violation in the charm sector at hadron colliders that has been of inspiration for the similar studies which are now ongoing at the CERN`s Large Hadron Collider. ····· 1036120664

The analytical study have been conducted by adopting the ICEPAC model for seasonal and annual times of the years (2009-2011) within the solar cycle 24. The analytical investigation for the behavior of ionospheric parameters has been conducted for the local (Iraqi) and regional (Middle East) zones. A simplified ionospheric empirical model (SIEM) has been suggested to predict the ionospheric parameters (MUF & FOT). The suggested model based in it`s construction on the correlated relationship between the geographical locations coordinates of receiver stations and the dataset of the MUF and FOT parameters that generated from the ICEPAC model. Predictions of the ionospheric parameters using the SIEM model show a good fitting with theoretical values that calculated using the international models.

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The detection of gravitational waves coming from the universe is a challenging task and even though experimental efforts have been going on since several decades, so far no direct detection has been achieved. There is only strong indirect evidence of the existence of gravitational radiation coming from binary pulsar systems. The commissioning of a gravitational wave detector is a complex work, consisting in a large number of different tasks. This thesis presents an investigation on an alternative method to compensate thermal effects, based, not on the addition of power on the test mass, rather on the removal of power. This method ( Directional Radiative Cooling or DRC), already described in literature, relies on the radiative heat exchange between the mirror and a cold body. It is present also a description of the DRC that exploits the focusing capability of parabolic mirrors to increase the efficiency of the radiative heat exchange. The results of optical and thermo-structural simulations are reported. The prototype it is described in detail to evaluate the performances of the method.

As the ions drift upward along geomagnetic flux tubes, they move from collision-dominated (ion barosphere) to collision less (ion exosphere) regions. A transition layer is embedded between these two regions where the ion characteristics change rapidly. So, this thesis deals with modeling of major ions outflow in the polar cap at altitudes higher than 400km. Different ion outflow models are numerical investigated and the pros and cons of these models are discussed. Observations are crucial for model validations. In this work we have used Akebono Satellite observations, which showed that between 5000 and 9000km altitudes H+ and 0+ can have higher outflow velocities in the day-side region that on the night-side. classical polar wind model cannot explain fully these observations. In this thesis, in order to address the observation we discuss hydrodynamic model by considering driven shock wave. Most of observed properties are well explained by using this model than the traditional one. ····· 1036120473
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The mathematical description of shock waves has been a fundamental challenge in Fluid Dynamics and became a real problem for the calculations of the first thermonuclear explosions, during World War II. Two famous mathematicians, Von Neumann and R. D. Richtmyer, working at Los Alamos, addressed the issue by including an artificial viscosity to smooth the shock transition. In general, numerical solutions of hydrodynamic problems make use of two different grid points to represent the relevant variables, namely the Eulerian and Lagrangian representations. The arbitrariness related to the selection of grid points, ad hoc, is examined in detail in this book, as well as the reasons subjacent to the need to introduce an artificial viscosity. A new approach to Hydrodynamics is presented in which the specification of grid points is considered an intrinsic part of the dynamic problem and in which the discontinuities are taken into account in its own formulation. Based only in the Hamilton s Principle a set of differential equations is deduced for both dynamic variables and grid points. The formalism is applied to the study and analysis of supernova explosions. ····· 1036120304

For a given ensemble of non-abelian gauge theory vacuum extremal black holes carrying a nonzero pair of gauge charge and cosmological constant, we study the Gaussian fluctuations over an equilibrium ensemble and determine the criteria for the well-defined, non-degenerate, curved and regular state-space and chemical surfaces. From the notion of the fluctuation theory, we show for the extremal black hole ensembles that the global stability and phase transition curves algebraically reduce to a set of finite polynomials, as the function of the charge. The present research offers gauge/ gravity perspective for the thermodynamic geometries of the background black holes. The perspective study includes distribution theory, local and global stability domains for colored (non)extremal black holes, higher form gauge theories, (non)static (non)abelian black holes in (gauged) supergravities and their embeddings in string theories and M-theory. ····· 1036120242

The influence of one or more IJJs in the voltage state on other junctions in the IJJ array is not yet fully understood. Dynamical behaviour of Thallium thin fillm IJJ arrays was studied to understand how one junction in the voltage state influences the other junctions in the array. It was observed that dissipative environment in which the IJJ arrays are embedded plays a major role. Furthermore, switching of a single junction into the voltage state significantly changes the dissipation. IJJs were subsequently isolated from their environment by FIB-deposited tungsten resistors of resistance between 100 and 500 . The complete resistor-junction-resistor (RJR) structure is multibranched and shows a change in the DC current-voltage characteristics below and above the transition temperature of the tungsten.

A thorough assessment of a pre-existing method to quantify theoretical approach for low-dimensional systems is performed. The procedure to such method is implemented and used to predict the electrical response to an external electric field of finite 1D chains. This is relevant not just as a test of the method but also for understanding real materials, whose electrical response can be mimicked in terms of Hubbard model. The 1D case, in particular, can provide important insights into the nonlinear optical properties of polymers. Additionally, this book introduced and implemented a novel extension of the existing method in magnetic field. This is successfully applied to investigating magnetic properties of systems involving large ensemble averages. It also investigates the magnetic behavior of several systems using the computationally efficient atomic self-interaction correction scheme in density functional theory. ····· 1036120149

In the specific the background contribution coming from the materials used for the detector realization has to be minimized. Moreover the net reduction of the background produced by the bulk part of the apparatus has raised concerns about the background contribution coming from the surfaces. Many procedures and techniques were developed to minimize the presence of possible contaminants on detector surfaces. To succeed in this strategy a big effort was put in defining all possible mechanisms that lead to surface contaminations. The presence in air and gases of possible radioactive elements that can stick on the detector surfaces can lead to a recontamination process that will vanish all the applied cleaning procedures. Here is presented and analyzed the contribution to the background of rare events experiments like CUORE (DBD0v) and EDELWEISS (DM) produced by an exposure of their detector components to a Radon-222 contamination. ····· 1036120137

An investigation on the evolution of the ion-surface interaction along the trajectory of the moving particle away from the metal surface is highlighted. Accordingly, the charge exchange process between the emitted secondary particle and the solid surface is studied through out two mainly derived treatments, namely the semiclassical probability rate equation (based on the electron tunneling model) and the configurations interaction treatment. In the semiclassical probability rate equation we assumed that the occupation of the atomic level of the emitted secondary ions on leaving the solid surface can be changed following two competing processes of resonance charge exchange while all the electronics excitations are assumed to dissipate rapidly. ····· 1036120010

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray The The Standard Model (SM) of particle physics is a precise model of electroweak interactions. However, there is evidence from neutrino physics and astrophysical cosmology which is at odds with the SM framework. It appears likely that the validity of the SM will be compromised at energy scales of a few TeV. A more fundamental theory will certainly be required, and such development is already motivated by the existing dark matter and neutrino data. We confirm the viability of the Supersymmetric B-L extension of the SM as a natural Supersymmetric SM extension which resolves the neutrino mass problem, the dark matter problem, and the hierarchy problem, and which has the ability to explain the observed baryon asymmetry of the Universe. When we include quantum corrections to the Higgs potential of the model, we find that Radiative B-L symmetry breaking occurs through the interplay between large Majorana Yukawa couplings and SUSY breaking masses. This realization shows that B-L symmetry breaking naturally occurs at the TeV scale. ····· 1036119885
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Here approximate Lie symmetries are used to investigate the problem of energy in general relativity and in particular in gravitational waves (GW). For this purpose second-order approximate symmetries of the system of geodesic equations for the Reissner-Nordström, Kerr, Kerr-Newman and GW spacetimes are studied. It is shown that in the second-order approximation, energy must be rescaled for these spacetimes. Since GW spacetimes are time-varying vacuum solutions of Einstein`s equations, there is no unambiguous means to define their energy content. Here a definition, using slightly broken symmetries is proposed. A problem is noted with the use of the proposal for pp waves. To attain a better understanding of the implications of this proposal we also use an artificially constructed time-varying non-vacuum plane symmetric metric and evaluate its Weyl and stress-energy tensors so as to obtain the gravitational and matter components separately and compare them with the energy content obtained by our proposal. The procedure is also used for cylindrical GWs. The usefulness of the definition is demonstrated by the fact that it leads to a result on whether GWs suffer self-damping. ····· 1036119700
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Geometrical and topological considerations are increasingly important in fundamental physics. This book shows how a certain explicit realization of toroidal topology can expedite and simplify the modeling of the elementary particles of physics, in particular how the taxonomy, interactions and particle attributes of the Standard Model can be realized but without its quarks, gluons or color . The particles of the model featured herein exist as general-relativistically-compatible solitons, in and of an otherwise undistorted space-time continuum. The book emphasizes their geometry and topology and the symmetries of their taxonomical combination. What is achieved is, in effect, an amalgamation of two of the major responses to the particle explosion that bedeviled mid-century physicists, one the non-reductionist Sakata model and the other the Gell-Mann/Zwieg introduction of quarks. Readers with some familiarity with the Standard Model should find this book interesting and provocative. ····· 1036119675

The linear dispersion properties of such perturbation modes in such a plasma system has been first examined by the normal mode analysis. The possibility for the formation of nonlinear coherent structures (viz. solitary waves and double layers) associated with such waves in the plasma system (under consideration) has been theoretically investigated. The reductive perturbation method, which is valid for small amplitude limit, and pseudopotential approach, which is valid for arbitrary amplitude waves, has been applied to study the basic features of solitary waves (SWs) and double layers (DLs). The co-existence of positive and negative SWs, and existence of either positive or negative DLs have been observed for certain range of different plasma parameters. The basic features and the underlying physics of the non-linear waves (SWs and DLs), which are relevant to some astrophysical compact objects (e.g. white dwarfs, neutron stars, etc.), have been pin-pointed and critically discussed. ····· 1036119600· 1 · ::::: · 20 ·· 21 ·· 22 ·· 23 ·· 24 ·· 25 ·· 26 · ::::: · 27 ·
