Transformations Between UML Diagrams

2003

The Unified Modeling Language (UML) provides various diagram types for describing a system from different perspectives or abstraction levels. Hence, UML diagrams describing the same system are dependent and strongly overlapping. In this paper we study how this can be exploited for specifying transformation operations between different diagram types. We discuss various general approaches and viewpoints of model transformations in UML. The source and target diagram types for useful transformations are analyzed and given categories. The potentially most interesting transformation operations are discussed in detail. It is concluded that the transformation operations can automate a substantial p…

Recepción escénica de Richard III en España

2020

La presente tesis doctoral analiza la recepción escénica en España de Richard III, de W. Shakespeare, desde 2005 hasta 2019, prestando atención a los diferentes contextos de producción y recepción de las adaptaciones realizadas, tanto en castellano como en gallego y catalán. El trabajo presta atención, en primer lugar, al texto de partida, particularmente complejo en esta obra. Analiza, a continuación, las distintas adaptaciones seleccionadas, atendiendo a sus transformaciones a nivel de estructura dramática, configuración de personajes, utilización de espacio y tiempo, textura lingüística y tono, análisis que se completa con la atención a los diferentes sistemas semióticos que intervienen …

Recepción escénica de Richard III en España

2020

Esta tesis doctoral tiene como principal objetivo el análisis de la recepción escénica de la obra Richard III, de William Shakespeare, entre los años 2005 y 2019. Para ello, en primer lugar analizamos el hipotexto shakesperiano y realizamos un recorrido por las principales adaptaciones de la misma a lo largo de la historia, no solo en el contexto anglófono, también en otros contextos como Europa y Oriente Medio, por ejemplo. En segundo lugar, se han analizado las adaptaciones y versiones libres que se han representado en nuestro país en el mencionado periodo de tiempo. Se ha llevado a cabo análisis a todos los niveles, a nivel lingüistico y textual, de personajes, de los elementos semiótico…

PSMA6 (rs2277460, rs1048990), PSMC6 (rs2295826, rs2295827) and PSMA3 (rs2348071) genetic diversity in Latvians, Lithuanians and Taiwanese

2014

PSMA6 (rs2277460, rs1048990), PSMC6 (rs2295826, rs2295827) and PSMA3 (rs2348071) genetic diversity was investigated in 1438 unrelated subjects from Latvia, Lithuania and Taiwan. In general, polymorphism of each individual locus showed tendencies similar to determined previously in HapMap populations. Main differences concern Taiwanese and include presence of rs2277460 rare allele A not found before in Asians and absence of rs2295827 rare alleles homozygotes TT observed in all other human populations. Observed patterns of SNPs and haplotype diversity were compatible with expectation of neutral model of evolution. Linkage disequilibrium between the rs2295826 and rs2295827 was detected to be c…

Strain gradient plasticity, strengthening effects and plastic limit analysis

2010

Abstract Within the framework of isotropic strain gradient plasticity, a rate-independent constitutive model exhibiting size dependent hardening is formulated and discussed with particular concern to its strengthening behavior. The latter is modelled as a (fictitious) isotropic hardening featured by a potential which is a positively degree-one homogeneous function of the effective plastic strain and its gradient. This potential leads to a strengthening law in which the strengthening stress, i.e. the increase of the plastically undeformed material initial yield stress, is related to the effective plastic strain through a second order PDE and related higher order boundary conditions. The plas…

AN INEXPENSIVE ULTRA-HIGH-SPEED PHOTOGRAPHIC TECHNIQUE

1968

Commercial Ultra-High-Speed Cameras for framing rates over 50,000 f.p.s. are very expensive and yield a small number of frames (8 to 24) per run. The single-flash technique with increasing delays gives photographs at a high framing rate over a comparatively long time and, as described here, requires no special electronic equipment except a good flash unit and a general-purpose oscilloscope.

Practical design rules for single-channel ultra high-speed dense dispersion management telecommunication systems

2009

International audience; In this work, we establish some efficient and practical design rules for the implementation of single-channel ultra-high speed (>160-Gbit/s) telecommunication systems based on dense dispersion management. Moreover, we analyze some of actual implementation issues such as slope compensation scenario, junction losses, polarization mode dispersion and chromatic dispersion fluctuations.

Mechanical and dentin bond strength properties of the nanosilver enriched glass ionomer cement

2019

Background The aim of this study was to investigate the mechanical properties and dentin microshear bond strength of a conventional glass ionomer cement (GIC) compared to GIC supplemented with silver nanoparticles (SNPs) at 0.1% and 0.2% (w/w). Material and Methods SNPs were incorporated into a conventional GIC at 0.1% and 0.2% (w/w). The unmodified GIC was used as the control group. Compressive strength, flexural strength, and micro-shear bond strength (µSBS) to dentin were evaluated using a universal testing machine. Surface microhardness was determined using a Vickers microhardness tester. The data were analyzed using one-way analysis of variance (ANOVA) and Tukey’s test. Results GICs co…

Influence of preheating on mechanical and surface properties of nanofilled resin composites

2019

Background Resin composite preheating is an innovative method that could be clinically beneficial by improving the handling properties, marginal adaptation, and surface properties of uncured nanofilled resin composite materials. There is conflict and unclear information regarding the effect of preheating on the microhardness, fracture toughness and surface roughness of nanofilled resin composites. Thus, it is important to assess whether dental clinicians can adopt preheating procedures without compromising composite mechanical strength. Objective: The purpose of this study was to evaluate the effect of preheating on microhardness, fracture toughness and surface roughness of nanofilled resin…
