Monitoring of Engineering Applications

This paper presents a license monitoring system implemented at CERN in the Computing for Engineering (CE) group of the Information Technology (IT) division. The system gathers statistics on the use of the different software products supported by the group on both Windows and Unix platforms. The web is used for all aspects of the project; data presentation and associated interfaces. The system is completely automated. Manual intervention is required only when there are new products to be monitored. Certain technical details of this work have been reported elsewhere

The GOODSTEP project: General Object-Oriented Database for Software Engineering Processes

The goal of the GOODSTEP project is to enhance and improve the functionality of a fully object-oriented database management system to yield a platform suited for applications such as software development environments (SDEs). The baseline of the project is the O2 database management system (DBMS). The O2 DBMS already includes many of the features regulated by SDEs. The project has identified enhancements to O2 in order to make it a real software engineering DBMS. These enhancements are essentially upgrades of the existing O2 functionality, and hence require relatively easy extensions to the O2 system. They have been developed in the early stages of the project and are now exploited and validated by a number of software engineering tools built on top of the enhanced O2 DBMS. To ease tool construction, the GOODSTEP platform encompasses tool generation capabilities which allow for generation of integrated graphical and textual tools from high-level specifications. In addition, the GOODSTEP platform provides a software process toolset which enables modeling, analysis and enaction of software processes and is also built on top of the extended O2 database. The GOODSTEP platform is to be validated using two CASE studies carried out to develop an airline application and a business application

Cardiac tamponade associated with a peripheral vein central venous catheter

We present a case of cardiac tamponade associated with placement of a central venous catheter (CVC) via a peripheral vein in a 14-year-old girl with idiopathic scoliosis undergoing corrective surgery. A number of complications have been described in association with CVC misplacement. Sporadic cases of cardiac tamponade from this have been reported, but the actual incidence is unknown. Death from cardiac tamponade attributed to CVCs ranges from 65 to 100%. In our patient, cannulation of the pericardiophrenic vein was probably the cause of cardiac tamponade, based on radiological evidence that the initial location of the catheter was near the right atrium and possibly at the outlet of the pericardiophrenic vein. The catheter could have advanced into the vein and then to the pericardial sac with postural changes. The acute clinical course of cardiac tamponade in our patient had potentially lethal hemodynamic repercussions. The main diagnostic test for this condition is echocardiography and the only effective treatment is drainage of the pericardial effusion. Echocardiography should be performed before pericardiocentesis except in life-threatening situations or high clinical suspicion. Although they are rare, it is important to be aware of the potential for CVC complications

Ansiedad y respuestas electrofisiológicas a una tarea de estrés mental tras un ejercicio aeróbico máximo

El objetivo del presente trabajo fue analizar las relaciones de la ansiedad con determinadas respuestas fisiológicas a una tarea de estrés mental. Para ello, se tomó una muestra de deportistas de élite varones de la Comunidad Valenciana de diferentes disciplinas deportivas. De acuerdo con las puntuaciones que los sujetos obtuvieron en las escalas STAI-R y STAI-E, completadas antes y después respectivamente, de una ergometría máxima, fueron separados en dos grupos extremos de alta y baja ansiedad. Se registraron de forma computerizada la frecuencia cardíaca y la actividad electrodérmica antes, durante y después de una tarea Stroop en ordenador. Los niveles basales de actividad electrodérmica fueron más elevados en los sujetos con ansiedad-estado alta durante el periodo anterior a la realización de la tarea y en la fase de recuperación. Sin embargo, la frecuencia cardíaca no fue diferente en función de la ansiedad, aunque sí estaba relacionada positivamente con la ejecución en tarea

Preliminary morphologic and molecular study of teh Entoloma rusticoides group (Agaricales - Basidiomycota)

Es presenta un estudi sobre el grup rusticoides del gènere Entoloma subgènere Claudopus a la Península Ibérica. L'anàlisi filogenètica, sobre la base de 48 seqüències d'ITS i 45 seqüències de LSU, entre les quals, les dels tipus de 8 dels tàxons analitzats, mostra una marcada diversitat genètica que concorda amb la notable variabilitat observada en aquest grup. D'acord amb aquest fet, es descriuen els següents nous tàxons: E. almeriense, E. graphitipes f. cystidiatum, E. halophilum, E. muscoalpinum i E. phaeocarpum. A més, es tipifiquen E. phaeocyathus i E. rusticoides. S'inclouen claus provisionals d'identificació. S'aporten descripcions macro i microscòpiques, dibuixos i fotografies de la majoria dels tàxons estudiats.A study of the Entoloma rusticoides-group (subgenus Claudopus) in the Iberian peninsula is presented. Phylogenetic inference, based on 48 nrITS and 45 28S nrLSU sequences, including those of 8 type specimens, revealed a high genetic diversity, in accordance with the observed morphological variability in this group. In addition new taxa are proposed to accomodate independent lineages (E. almeriense, E. graphitipes f. cystidiatum, E. halophilum, E. muscoalpinum and E. phaeocarpum) and the typification of E. phaeocyathus and E. rusticoides is proposed. Preliminary taxonomic keys are included to help identification. For most species macro and microscopic descriptions, drawings and photographs are presented

Onset of a Propagating Self-Sustained Spin Reversal Front in a Magnetic System

The energy released in a magnetic material by reversing spins as they relax toward equilibrium can lead to a dynamical instability that ignites self-sustained rapid relaxation along a deflagration front that propagates at a constant subsonic speed. Using a trigger heat pulse and transverse and longitudinal magnetic fields, we investigate and control the crossover between thermally driven magnetic relaxation and magnetic deflagration in single crystals of Mn 12 -acetate

Automated Design of Common-Mode Suppressed Balanced Wideband Bandpass Filters by Means of Aggressive Space Mapping

The automated and unattended design of balanced microstrip wideband bandpass filters by means of aggressive space mapping (ASM) optimization is reported in this paper. The proposed filters are based on multisection mirrored stepped impedance resonators (SIRs) coupled through quarter-wavelength transmission lines, acting as admittance inverters.This work was supported by MINECO-Spain (projects TEC2013-47037-C5-1-R, TEC2013-40600-R, TEC2013-49221-EXP), Generalitat de Catalunya (project 2014SGR-157), Institucio Catalana de Recerca i Estudis Avancats (who awarded Ferran Martin), and by FEDER funds.Sans, M.; Selga, J.; Velez, P.; Rodriguez Perez, AM.; Bonache Albacete, J.; Boria Esbert, VE.; Martin, F.
