Kurzemes un Zemgales hercogistes landtāgā skatīto jautājumu analīze (1682-1698)

2018

Pētījums veltīts maz pētītam jautājumam Latvijas vēsturē Kurzemes un Zemgales hercoga Frīdriha Kazimira valdīšanas laikam, jo 17. gadsimta nogales hercogistes vēstures pētniecība palikusi hercoga Jēkaba valdīšanas laika un 18. gadsimta sākuma cīņas par varu hercogistē ēnā. Pētījuma mērķis ir caur hercogistes landtāgu lēmumiem analizēt aktualitātes un problēmas laika periodā no 1682. gada līdz 1698. gadam. Pētījuma izstrādes laikā tika iegūta informācija par aktuāliem jautājumiem hercogistē saistībā ar baznīcu, zemnieku dzīves regulējumu, ekonomiku un tirdzniecību un ārpolitiku. Landtāgu lēmumu analīze atklāja būtisku visas hercogistes pastāvēšanas laika posma iezīmi – hercoga un muižniecība…

Sag, wie hältst Du's mit Grün-Rot? Die grün-rote Landesregierung im Urteil der Wähler 2011 bis 2015

2016

In unserem Beitrag analysieren wir, wie die Burgerinnen und Burger den Regierungswechsel und die Ubernahme der Regierungsgeschafte durch die neue grun-rote Regierung wahrgenommen, wie sich die Regierungs- und Parteienzufriedenheit (ausgedruckt durch die hypothetische Wahlentscheidung) im Zeitverlauf entwickelt haben und was die Determinanten der Zufriedenheit sind. Unsere Analysen basieren dabei auf insgesamt sechs reprasentativen telefonischen Befragungen im Zeitraum von November 2011 bis Oktober 2015. Wir konnen zeigen, dass im Laufe der Legislaturperiode die vor der Wahl stattgefundenen Ereignisse mehr und mehr an Bedeutung fur die Bewertung der Regierungsleistung verlieren. Die Landesre…

Zero Viscosity Limit for Analytic Solutions, of the Navier-Stokes Equation on a Half-Space.¶I. Existence for Euler and Prandtl Equations

1998

This is the first of two papers on the zero-viscosity limit for the incompressible Navier-Stokes equations in a half-space. In this paper we prove short time existence theorems for the Euler and Prandtl equations with analytic initial data in either two or three spatial dimensions. The main technical tool in this analysis is the abstract Cauchy-Kowalewski theorem. For the Euler equations, the projection method is used in the primitive variables, to which the Cauchy-Kowalewski theorem is directly applicable. For the Prandtl equations, Cauchy-Kowalewski is applicable once the diffusion operator in the vertical direction is inverted.

Zero Viscosity Limit for Analytic Solutions of the Navier-Stokes Equation on a Half-Space.¶ II. Construction of the Navier-Stokes Solution

1998

This is the second of two papers on the zero-viscosity limit for the incompressible Navier-Stokes equations in a half-space in either 2D or 3D. Under the assumption of analytic initial data, we construct solutions of Navier-Stokes for a short time which is independent of the viscosity. The Navier-Stokes solution is constructed through a composite asymptotic expansion involving the solutions of the Euler and Prandtl equations, which were constructed in the first paper, plus an error term. This shows that the Navier-Stokes solution goes to an Euler solution outside a boundary layer and to a solution of the Prandtl equations within the boundary layer. The error term is written as a sum of firs…

Search for First Harmonic Modulation in the Right Ascension Distribution of Cosmic Rays Detected at the Pierre Auger Observatory

2011

We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 × 1017 eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude measurements of the first harmonic modulation in the right-ascension distribution. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations.

Cómo los corpus pueden asistir a los estudiantes de traducción jurídica : la plataforma GENTT TransTools Corpora y Sketch Engine

2019

 
 Esta aportación analiza la aplicación de corpus a la enseñanza de la traducción jurídica en la educación superior utilizando la plataforma GENTT TransTools Corpora y Sketch Engine. En primer lugar, revisaremos la bibliografía sobre experiencias previas de aplicación de corpus textuales a la enseñanza de la traducción jurídica. A continuación, describiremos la experiencia de 10 años del grupo GENTT en el aula de traducción especializada, en la que hemos aplicado una metodología basada corpus y dirigida a promover la formación guiada y el aprendizaje constructivo y cooperativo. Estas experiencias sugieren que los corpus monolingües, multilingües y traducidos de textos especializados c…

Critical Digital Editions of Theatrical Texts: The Example of La estrella de Sevilla

2014

This article analyses the process of creating a multilingual and multimedia critical digital edition of the text from the Spanish Golden Age La Estrella de Sevilla. It begins with a reflection on what a critical digital edition is, and then it presents different projects about digital editions of theatrical texts as well as some practical issues on the encoding of the texts included in this digital critical edition.

Sampled-Data Control of Spacecraft Rendezvous with Discontinuous Lyapunov Approach

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/814271 Open Access This paper investigates the sampled-data stabilization problem of spacecraft relative positional holding with improved Lyapunov function approach. The classical Clohessy-Wiltshire equation is adopted to describe the relative dynamic model. The relative position holding problem is converted into an output tracking control problem using sampling signals. A time-dependent discontinuous Lyapunov functionals approach is developed, which will lead to essentially less conservative results for the stability analysis and control…
