Towards a Security Competence of Software Developers
2020
Software growth has been explosive as people depend heavily on software on daily basis. Software development is a human-intensive effort, and developers' competence in software security is essential for secure software development. In addition, ubiquitous computing provides an added complexity to software security. Studies have treated security competences of software developers as a subsidiary of security engineers' competence instead of software engineers' competence, limiting the full knowledge of the security competences of software developers. This presents a crucial challenge for developers, educators, and users to maintain developers' competences in security. As a first step in pushi…
Finding Software Bugs in Embedded Devices
2021
AbstractThe goal of this chapter is to introduce the reader to the domain of bug discovery in embedded systems which are at the core of the Internet of Things. Embedded software has a number of particularities which makes it slightly different to general purpose software. In particular, embedded devices are more exposed to software attacks but have lower defense levels and are often left unattended. At the same time, analyzing their security is more difficult because they are very “opaque”, while the execution of custom and embedded software is often entangled with the hardware and peripherals. These differences have an impact on our ability to find software bugs in such systems. This chapt…
Performance Estimation using the Fitness-Fatigue Model with Kalman Filter Feedback
2016
Abstract Tracking and predicting the performance of athletes is of great interest, not only in training science but also, increasingly, for serious hobbyists. The increasing availability and use of smart watches and fitness trackers means that abundant data is becoming available, and the interest to optimally use this data for performance tracking and training optimization is great. One competitive model in this domain is the 3-time-constant fitness-fatigue model by Busso based on the model by Banister and colleagues. In the following, we will show that this model can be written equivalently as a linear, time-variant state-space model. With this understanding, it becomes clear that all meth…
Pulsed Electric Field Processing of Fruit Juices
2018
Abstract Fruit juices and other liquid foods constitute an important source of bioactive compounds. However, the techniques used for their processing may cause alterations in their contents, and consequently they do not provide the benefits expected by the consumer. This fact has led to the increasing use of nonthermal processing technologies, such as pulsed electric field (PEF), which have been developed over recent decades as alternative technologies to thermal pasteurization of liquid foods. Researchers have previously studied the effects of PEF on the main compounds affecting the quality and the health-related properties. The reported results show that PEF could be used to pasteurize fr…
Incidence de l’endophtalmie aiguë postopératoire après chirurgie de la cataracte par phacoémulsification et injection intracamérulaire d’antibiotique…
2016
National audience; Introduction La chirurgie de la cataracte est l’intervention la plus fréquente dans le monde. Parmi ses complications, l’endophtalmie aiguë postopératoire (EAPO) est une infection intraoculaire sévère, qui peut conduire à la cécité. Les objectifs étaient de déterminer l’incidence de l’EAPO après chirurgie de la cataracte par phacoémulsification en France de 2005 à 2014 et d’analyser l’association entre injection intracamérulaire d’antibiotique (IICA) et EAPO. Méthodes Tous les patients hospitalisés pour une chirurgie de la cataracte en France entre le 1er janvier 2005 et le 31 décembre 2014 ont été identifiés dans le programme de médicalisation des systèmes d’information …
Biomarcadores de peroxidación lipídica en el humor acuoso de pacientes con glaucoma primario de ángulo abierto
2016
Resumen Objetivo Investigamos la peroxidacion lipidica (PEROX) en el glaucoma primario de angulo abierto (GPAA) y si este mecanismo puede relacionarse con su progresion. Material y metodos Estudio prospectivo observacional, transversal, analitico no experimental de casos y grupo comparativo, con seleccion de 175 pacientes quirurgicos, distribuidos en: 1) grupo diagnosticado de GPAA (GG; n = 88) y 2) grupo comparativo de pacientes con cataratas (GC; n = 87). Se han obtenido datos demograficos, caracteristicas de los participantes y estilo de vida. Se realizo un examen oftalmologico centrado en GPAA. Se obtuvieron muestras de humor acuoso al principio de la cirugia programada, que fueron proc…
La atropina superdiluida al 0,01% frena el aumento de miopía en niños-adolescentes. Un estudio a largo plazo 5 años de evolución: seguridad y eficacia
2018
Resumen Objetivo Confirmar la seguridad y eficacia de la aplicacion diaria nocturna de atropina superdiluida al 0,01% en colirio para frenar la progresion de la miopia en los ninos. Material y metodos Un total de 200 ninos de 9-12 anos randomizados en el grupo tratado y control sin tratamiento. Se realizo refraccion bajo cicloplejia. Resultados La progresion miopica del grupo tratado fue de −0,14 ± 0,35 frente a −0,65 ± 0,54 en el grupo control, sin tratamiento. La obligacion de suspender el tratamiento por efectos secundarios fue solo del 2% de los casos. Conclusion La atropina superdiluida (0,01%) en colirio es eficaz y bien tolerada, reduciendo a la cuarta parte la progresion de la miopi…
Paraproteinämische Keratopathie als klinisches Zeichen einer monoklonalen Gammopathie
2017
ZusammenfassungPatienten mit monoklonaler Gammopathie können eine behandlungsbedürftige paraproteinämische Keratopathie (PPK) aufweisen. Die PPK muss gegenüber verschiedenen Formen von Hornhautdystrophie, einzelnen systemischen Stoffwechselstörungen mit Hornhautbeteiligung sowie gegenüber immunologischen und inflammatorischen Hornhauterkrankungen abgegrenzt werden.
