Implementación y uso clínico de la radioterapia adaptativa. Informe del grupo de trabajo de radioterapia adaptativa de la Sociedad Española de Física…
2021
La radioterapia adaptativa (Adaptive Radiation Therapy, ART) se puede definir como la modificación del plan de tratamiento administrado a un paciente durante el curso de la radioterapia para tener en cuenta los cambios en la anatomía.
 La aplicación de ART supone un cambio en el proceso radioterápico que implica el uso de numerosos recursos adicionales, no estando implementada de forma general. Así, aun tratándose de una idea introducida hace más de 20 años, todavía a fecha de hoy son objeto de estudio muchos de los aspectos que definen la ART: la decisión de proceder a la nueva planificación del tratamiento, el momento óptimo para adaptar el plan, el umbral dosimétrico o anatómico que…
Evolution of secondary software product businesses: Momentum of concurrent enterprising
2005
A growing part of commercial software production is provided by the so-called secondary software industry, involving both software products and services offered by other industries than the actual software industry, i.e. the primary industry. We have been investigating the evolution of businesses in the secondary software industry in two phases, first by developing a framework to analyse the change of host industries from closed and vertical to open and horizontal especially in terms of software products. Secondly, we have studied a set of selected industries in a pivotal era called the momentum of concurrent enterprising in this paper. The key finding is: the value creation is moving towar…
XPL the Extensible Presentation Language
2009
The last decade has witnessed a growing interest in the development of web interfaces enabling both multiple ways to access contents and, at the same time, fruition by multiple modalities of interaction (point-and-click, contents reading, voice commands, gestures, etc.). In this paper we describe a framework aimed at streamlining the design process of multi-channel, multimodal interfaces enabling full reuse of software components. This framework is called the eXtensible Presentation architecture and Language (XPL), a presentation language based on design pattern paradigm that keeps separated the presentation layer from the underlying programming logic. The language supplies a methodology to…
Low Degree of Separation Does Not Guarantee Easy Coordination
2012
In the times of increased global competition, software companies are forced to search for more effective development practices and often team up with onshore and offshore partners to develop faster and better products. In this paper we empirically explore a highly distributed onshore development project with a complex coordination structure. Our findings demonstrate that onshore development projects are not protected from coordination and communication challenges and task allocation complexities. Previously reported qualitative findings regarding organizational problems in this paper are supplemented with quantitative measurements of the true coordination delays and additional analysis of c…
Voxel-based General Voronoi Diagram for Complex Data with Application on Motion Planning
2020
One major challenge in Assembly Sequence Planning (ASP) for complex real-world CAD-scenarios is to find appropriate disassembly paths for all assembled parts. Such a path places demands on its length and clearance. In the past, it became apparent that planning the disassembly path based on the (approximate) General Voronoi Diagram (GVD) is a good approach to achieve these requirements. But for complex real-world data, every known solution for computing the GVD is either too slow or very memory consuming, even if only approximating the GVD.We present a new approach for computing the approximate GVD and demonstrate its practicability using a representative vehicle data set. We can calculate a…

Influence of Background Knowledge and Language Proficiency on Comprehension of Domain-Specific Texts by University Students
2019
This paper presents the results of a quantitative study that explores two factors contributing to reading comprehension of domain specific texts, namely level of language proficiency and background knowledge. Overall, 32 students participated in the study by taking two custom-designed reading comprehension tests. The test scores were further analyzed using SPSS statistical software. The results of statistical tests revealed the differences between study groups as well as the effects of compensation. More precisely, the most proficient group scored higher on almost all tests and completed the tests more quickly than the remaining groups. The statistical tools used to test the data showed th…
Computation of Yvon-Villarceau circles on Dupin cyclides and construction of circular edge right triangles on tori and Dupin cyclides
2014
Ring Dupin cyclides are non-spherical algebraic surfaces of degree four that can be defined as the image by inversion of a ring torus. They are interesting in geometric modeling because: (1) they have several families of circles embedded on them: parallel, meridian, and Yvon-Villarceau circles, and (2) they are characterized by one parametric equation and two equivalent implicit ones, allowing for better flexibility and easiness of use by adopting one representation or the other, according to the best suitability for a particular application. These facts motivate the construction of circular edge triangles lying on Dupin cyclides and exhibiting the aforementioned properties. Our first contr…
Generic attribute deviation metric for assessing mesh simplification algorithm quality
2002
International audience; This paper describes an efficient method to compare two triangular meshes. Meshes considered here contain geometric features as well as other surface attributes such as material colors, texture, temperature, radiation, etc. Two deviation measurements are presented to assess the differences between two meshes. The first measurement, called geometric deviation, returns geometric differences. The second measurement , called attribute deviation, returns attribute differences regardless of the attribute type. In this paper we present an application of this method to the Mesh Simplification Algorithm (MSA) quality assessment according to the appearance attributes. This ass…
RNN- and LSTM-Based Soft Sensors Transferability for an Industrial Process
2021
The design and application of Soft Sensors (SSs) in the process industry is a growing research field, which needs to mediate problems of model accuracy with data availability and computational complexity. Black-box machine learning (ML) methods are often used as an efficient tool to implement SSs. Many efforts are, however, required to properly select input variables, model class, model order and the needed hyperparameters. The aim of this work was to investigate the possibility to transfer the knowledge acquired in the design of a SS for a given process to a similar one. This has been approached as a transfer learning problem from a source to a target domain. The implementation of a transf…
