Combining hashing and enciphering algorithms for epidemiological analysis of gathered data.
2008
Summary Objectives: Compiling individual records coming from different sources is necessary for multi-center studies. Legal aspects can be satisfied by implementing anonymization procedures. When using these procedures with a different key for each study it becomes almost impossible to link records from separate data collections. Methods: The originality of the method relies on the way the combination of hashing and enciphering techniques is performed: like in asymmetric encryption, two keys are used but the private key depends on the patient’s identity. Results: The combination of hashing and enciphering techniques provides a great improvement in the overall security of the proposed scheme…
Multi-beam cooperative frequency reuse for coordinated multi-point transmission
2010
Coordinated multi-point (CoMP) joint transmission is considered in the 3rd generation partnership project (3GPP) long term evolution (LTE)-advanced as a key technique to mitigate inter-cell interference and improve the cell-edge performance. To effectively apply CoMP joint transmission, efficient frequency reuse schemes need to be designed to support resource management cooperation among coordinated cells. However, most of the existing frequency reuse schemes are not suitable for CoMP systems due to not considering multi-point joint transmission scenarios in their frequency reuse rules. In addition, the restrictions of frequency resources in those schemes result in a high blocking probabili…
Multidisciplinary intervention in the management of breathlessness in people with non-malignant chronic diseases in advanced situation
2018
Resumen El presente trabajo muestra una revisión crítica de un artículo en que se presentan los resultados de un ensayo clínico realizado en un hospital de Reino Unido para estudiar los resultados de una intervención con enfoque paliativo utilizada en el manejo de la disnea en pacientes con enfermedades crónicas en fases avanzadas. Tras el resumen del artículo, destacando los principales resultados obtenidos, se presenta la revisión crítica del artículo, en la que se ha intentado analizar tanto el diseño como la metodología utilizada en el ensayo clínico, como las implicaciones para la práctica de enfermería y especialmente en el ámbito de los cuidados paliativos. Abstract This work shows a…
El sistema regional andaluz de los servicios avanzados (SA) con los distintos sectores económicos
2002
El artículo estudia la caracterización del entorno productivo de los SA a través de la creación de espacio relacional. El objetivo es medir su nivel tecnológico, el del espacio productivo andaluz y conocer en qué fase de la sociedad servindustrial se encuentra. Las empresas de gestión de calidad y de consultoría son las que concentran el mayor número de servicios comprados frente a los Organismos Públicos de Investigación (OPIs) que suministran el grueso de la I+D a los sectores económicos. Gran parte de la contratación de los SA y de la cooperación se realiza a escala regional, pero la densidad de relaciones es baja y poco contínua. Se trata de un sistema regional fragmentado. This paper s…
MAGICPL: A Generic Process Description Language for Distributed Pseudonymization Scenarios
2021
Abstract Objectives Pseudonymization is an important aspect of projects dealing with sensitive patient data. Most projects build their own specialized, hard-coded, solutions. However, these overlap in many aspects of their functionality. As any re-implementation binds resources, we would like to propose a solution that facilitates and encourages the reuse of existing components. Methods We analyzed already-established data protection concepts to gain an insight into their common features and the ways in which their components were linked together. We found that we could represent these pseudonymization processes with a simple descriptive language, which we have called MAGICPL, plus a relati…
GPCALMA: A Grid-based tool for mammographic screening
2005
The next generation of High Energy Physics (HEP) experiments requires a GRID approach to a distributed computing system and the associated data management: the key concept is the Virtual Organisation (VO), a group of distributed users with a common goal and the will to share their resources. A similar approach is being applied to a group of Hospitals which joined the GPCALMA project (Grid Platform for Computer Assisted Library for MAmmography), which will allow common screening programs for early diagnosis of breast and, in the future, lung cancer. HEP techniques come into play in writing the application code, which makes use of neural networks for the image analysis and proved to be useful…
Review of Knowledge Management Models for Implementation within Advanced Product Quality Planning
2014
The purpose of this paper is to review different Knowledge Management Models (KMM) based on their strengths and weaknesses and to ascertain their possible implementation within the scope of the Advanced Product Quality Planning (APQP) procedure. The KMM listed are selected based on an extensive literature review. They are presented in a visual manner and analyzed based on their structure and features, versus a predetermined set of criteria. This study offers an overview and a critical discussion of the merits and faults of a number KMM and suggests possible improvement avenues.
Development of the UV/ion shields for the Advanced X-ray Astrophysics Facility high-resolution camera (AXAF HRC)
1994
The Advanced X-ray Astrophysics Facility (AXAF) is a major NASA space observatory (launch 1998). One of its two focal plane detectors is the High Resolution Camera (HRC) assembly consisting of two microchannel plate (MCP) based detectors. Key components of the two HRC detectors are UV/Ion shields consisting of metalized sub-micron plastic membranes, designed to prevent UV light and low energy charged particles from reaching the detectors' sensitive surfaces. We discuss the design issues and present results of recent measurements and tests. Soft X-ray/UV transmission measurements have been conducted at the Space Science Laboratory (SSL), University of California at Berkeley, and at the Osser…

Heterogeneous photocatalysis: a promising advanced oxidation process
2018
This chapter reports the fundamentals of heterogeneous PC. In particular, different kinetic models and the influence of some parameters (such as pH, temperature, light intensity) on the rate of PC are described, and the effects of some photocatalyst modifications are discussed. Methods for photoreactor modeling are analyzed and the coupling of PC with other AOPs using H2O2, O3, and peroxydisulfate are discussed.
