Relaxation of a weakly discontinuous functional depending on one control function
2008
The paper considers an optimal control problem of the typewhere the set M of admissible controls consists of all measurable vector‐functions h, which can take only two values h1 or h2. It is shown that the relaxation of this problem can be explicitly computed by rank‐one laminates.
Modelling and analysing oriented fibrous structures
2014
Abstract. A mathematical model for fibrous structures using a direction dependent scaling law is presented. The orientation of fibrous nets (e.g. paper) is analysed with a method based on the curvelet transform. The curvelet-based orientation analysis has been tested successfully on real data from paper samples: the major directions of fibrefibre orientation can apparently be recovered. Similar results are achieved in tests on data simulated by the new model, allowing a comparison with ground truth. peerReviewed
Towards a Contingency Framework for Engineering an Enterprise Architecture Planning Method
2007
Enterprise architecture (EA) has a key role in managing and relating business strategies and processes, information systems, and IC technologies. EA planning devises an EA plan with development steps to make necessary enhancements to the current state of the affairs in EA. Accomplishing EA planning in a systematic and efficient manner requires the availability of frameworks and methods suitable to the situation at hand. The selection and adaptation of these methodical artifacts for the use of EA planning is often quite challenging in practice. We argue that the contingency approach can help in these activities of method engineering (ME), and present a contingency framework (named here EACon…
Utilidad de la resonancia magnética en la predicción de la continencia urinaria tras prostatectomía radical endoscópica extraperitoneal
2015
Introducción: El cáncer de próstata es un problema de salud importante. Es la localización más frecuente de cáncer en el varón. Afortunadamente la tasa de curación es alta, con una tasa de supervivencia del 87% al año y del 65% a los 5 años. La mayor parte de los tumores que se diagnostican se encuentran es estadios órgano confinados. En la actualidad la mejor técnica para el estudio de extensión y para la planificación de una posible cirugía es la resonancia magnética. Si bien, la prostatectomía radical se define como el patrón de oro como terapia para el cáncer de próstata, no está exenta de complicaciones. La incontinencia urinaria es la morbilidad a largo plazo que más mina la calidad d…
Continuidad de las innovaciones tecnológicas: el reto de las intervenciones biomédicas de mejora humana
2013
One of the most recent debates among ethicists concerning the course of technological innovation is the human enhancement debate, which has been generated by the possibility of pushing human limits further by using the power of science. Many philosophers have warned us about the dangers of modifying human nature in a technical way. However, others argue that there are no morally salient differences between enhancing technical interventions and other kinds of technologies that human beings have taken to be usual for them. This paper shall critically analyze this argument. The main aim of this critical analysis is twofold, first, to show that people who make this argument are biased in severa…
On continua whose hyperspace of subcontinua is σ-locally connected
1999
Abstract We provide a structural characterization of all continua X whose hyperspace C ( X ) of all subcontinua is the countable union of Peano continua. Applying this result we prove that there exists a uniformly path connected continuum X with no continuous mapping from C ( X ) onto X.
