Adding Domain Analysis to Software Development Method
2002
The researchers in the field of software development regard the reuse of components as one possible approach when creating quality software in less time and with fewer people. When components are used and created in the software development, one critical success factor is the use of domain analysis (DA). We report an action case study where the DA technique is first integrated into an existing software development method and then refined based on the experience of using it in a pilot project. The results indicate that our approach produces reusable components across a company-wide domain and eases the use of them in other development projects within domain.
Enforcing Conceptual Modeling to improve the understanding of human genome
2010
It is widely accepted that the use of Conceptual Modeling techniques in modern Software Engineering leads to a more accurate description of the problem domain. The application of these techniques in the context of challenging domains as the human genome is a fascinating task. The relevant biological concepts should be properly addressed through the creation of the corresponding conceptual schema. This schema will improve the description of the global process followed from a DNA sequence to a fully functional protein. Once the conceptual model is established, the corresponding database is created. The database is intended to act as a unified repository of integrated information that will all…
Numerical Simulation of Thermal Effects in Coupled Optoelectronic Device-circuit Systems
2008
The control of thermal effects becomes more and more important in modern semiconductor circuits like in the simplified CMOS transceiver representation described by U. Feldmann in the above article Numerical simulation of multiscale models for radio frequency circuits in the time domain. The standard approach for modeling integrated circuits is to replace the semiconductor devices by equivalent circuits consisting of basic elements and resulting in so-called compact models. Parasitic thermal effects, however, require a very large number of basic elements and a careful adjustment of the resulting large number of parameters in order to achieve the needed accuracy.

Multiferroic BiFeO<inf>3</inf> for conductance control at the LaAlO<inf>3</inf>/SrTiO<inf>3</inf>-interface
2015
Multiferroic materials possessing both magnetic and ferroelectric order enable in principle to switch order parameters using not the direct reciprocal field, e.g. to switch the magnetization by an electric field or the electric polarization by a magnetic field. A recent breakthrough was achieved by the demonstration of the ferromagnetic switching of a Co layer with an electric field employing the multiferroic BiFeO 3 [1]. The latter material is a perovskite based oxide that shows stable ferro-electricity as well as an antiferromagnetic order at room temperature [2,3]. Due to a Dzyaloshinskii-Moriya interaction induced by rotation of oxygen octahedra leading to noncollinear Fe-O-Fe bonds a s…
Temperature-induced martensite in magnetic shape memory Fe2MnGa observed by photoemission electron microscopy
2012
The magnetic domain structure in single crystals of a Heusler shape memory compound near the composition Fe2MnGa was observed during phase transition by photoelectron emission microscopy at Beamline 11.0.1.1 of the Advanced Light Source. The behavior is comparable with recent observations of an adaptive martensite phase in prototype Ni2MnGa, although the pinning in the recent work is an epitaxial interface and in this work the effective pinning plane is a boundary between martensitic variants that transform in a self-accommodating way from the single crystal austenite phase present at high temperatures. Temperature dependent observations of the twinning structure give information as to the …
Production and study of spinor condensates of <sup>87</sup>Rb released from a magnetic trap
2009
We report on our study of spinor condensates in the F=2 state of 87Rb produced in an atomic cloud expanding after releasing from a magnetic trap. The experiments are conducted in the setup described in Ref. [1].
Single-crystal EPR spectroscopy of a Co(II) single-chain magnet
2013
Abstract An electron paramagnetic resonance (EPR) study of a single crystal of Co II -based single-chain magnets (SCM) is presented. Discrete resonant absorptions are associated to the presence of magnetic domains within the chains of finite lengths determined by a competition between intra-chain exchange interactions and thermally excited single spin fluctuations. The results are interpreted as a transition from single spin dynamics at high temperature ( T ∼20 K), associated to the Kramers doublet ground state of the individual Co II ions, to archetypical SCM dynamics at low temperatures, where intra-chain correlations form long magnetic domains, whose average length is imposed by the con…
Crystal field effects and magnetic properties of Dy2Te3
1995
Abstract Magnetic susceptibility and magnetization measurements are presented for Dy 2 Te 3 . By means of crystal field calculations the energy levels of ground state and crystal field potentials for Dy 3+ ions have been evaluated taking the exchange interactions into account.
Gobierno político y luchas sociales: patricios y malhechores. Siglos XIV y XV
1989
El gobierno municipal de Valencia desde mediados del siglo XIV se encuentra monopolizado por una oligarquía de ciudadanos. El patriciado urbano queda claramente diferenciado del resto de los habitantes de la ciudad, especialmente por sus actividades políticas y por su reproducción en el poder. Este grupo social no se identificaba con la "burguesía medieval" estando envuelto en las banderías nobiliarias que asolaban la ciudad, cuyo objetivo era el control del gobierno ciudadano, y también la política que desde allí guiaba los designios ciudadanos.
