Towards enabling privacy preserving smart city apps

2016

Smart city applications are increasingly relying on personally identifiable data. A disclosure of such a data to a platform provider and possible 3rd parties represents a risk to the privacy of the application users. To mitigate the privacy risk, two-layer privacy-preserving platform architecture is introduced, wherein the personally identifiable information is dealt with at the inner layer (executed in a trusted environment), whereas only generic and personally unidentifiable information is made available to the apps at the outer layer of the architecture — e.g., in a form of app-specific events. The essential requirements for the platform are described, and the architectural implications …

A Unified AMBER-Compatible Molecular Mechanics Force Field for Thiolate-Protected Gold Nanoclusters.

2016

We present transferable AMBER-compatible force field parameters for thiolate-protected gold nanoclusters. Five different sized clusters containing both organo-soluble and water-soluble thiolate ligands served as test systems in MD simulations, and parameters were validated against DFT and experimental results. The cluster geometries remain intact during the MD simulations in various solvents, and structural fluctuations and energetics showed agreement with DFT calculations. Experimental diffusion coefficients and crystal structures were also reproduced with sufficient accuracy. The presented parameter set contains the minimum number of cluster-specific parameters enabling the use of these p…

Coupling high-resolution satellite imagery with ALS-based canopy height model and digital elevation model in object-based boreal forest habitat type …

2014

We developed a classification workflow for boreal forest habitat type mapping. In object-based image analysis framework, Fractal Net Evolution Approach segmentation was combined with random forest classification. High-resolution WorldView-2 imagery was coupled with ALS based canopy height model and digital terrain model. We calculated several features (e.g. spectral, textural and topographic) per image object from the used datasets. We tested different feature set alternatives; a classification accuracy of 78.0 % was obtained when all features were used. The highest classification accuracy (79.1 %) was obtained when the amount of features was reduced from the initial 328 to the 100 most imp…

Towards Mitigating the Impact of UAVs on Cellular Communications

2018

The next generation of Unmanned Aerial Vehicles (UAVs) will rely on mobile networks as a communication infrastructure. Several issues need to be addressed to enable the expected potentials from this communication. In particular, it was demonstrated that flying UAVs perceive a high number of base stations (BSs), consequently causing more interferences on non-serving BSs. This unfortunately results in decreased throughput for ground user equipments (UEs) already connected. Such a problem could be a limiting factor for mobile network-enabled UAVs, due to its consequences on the quality of experience (QoE) of served UEs. This underpins the focus of this article, wherein the effect of UAVs' comm…

Visualising maritime vessel open data for better situational awareness in ice conditions

2018

Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…

Design of mobile phones for older adults : An empirical analysis of design guidelines and checklists for feature phones and smartphones

2017

Design guidelines and checklists are suggested as a useful tool in the development and evaluation of interface design of mobile phones for older adults. Given the intense evolution of mobile phone design, understanding how the design guidelines and checklists have taken into account the advances in mobile phone usability for older adults is important for their correct application and future development. Thus, this study explores the usability dimensions of mobile phone design for older adults and the related changes in terms of time and the type of device (feature phones vs. smartphones) based on an expert coding of the eight mobile phone design guidelines and checklists for older adults pu…

Reducing Relationship Conflict in Virtual Teams With Diversity Faultlines: The Effect of an Online Affect Management Intervention on the Rate of Grow…

2020

The aim of this study was to analyze the effect of an online affect management intervention on relationship conflict through the rate of growth of team resilience in virtual teams with diversity faultlines. Fifty-two 4-person teams participated in a randomized controlled trial design with repeated measures (i.e., three measurement occasions). Teams were randomly assigned to either an intervention designed to help them manage emotions in virtual teams or a control condition. Our findings showed that affect management can reduce the level of relationship conflict in virtual teams with diversity faultlines and that this effect can be explained by the pattern of change in team resilience in re…

Teoría de la educación : educación y cultura en la sociedad de la información

2016

Las nuevas tecnologías de la información y la comunicación han construido un nuevo contexto: la sociedad de la información, en la que la escuela sufrirá necesariamente cambios importantes. La integración de estas nuevas tecnologías en la educación será adecuada si se realiza desde una perspectiva pedagógica activa y constructiva. En esa dinámica hay una serie de factores muy importantes para una integración eficaz: el apoyo institucional y el desarrollo de políticas pertinentes, lo que comporta dotación de infraestructuras y formación de los profesores, el apoyo de los equipos directivos de los centros, y el desarrollo de modelos de evaluación coherentes. The information and communication n…

Protección de la infancia y nuevas tecnologias de la comunicación : el código PEGI de regulación de los videojuegos y juegos on-line

2008

Monográfico con el título: 'Videojuegos: una herramienta en el proceso educativo del 'Homo Digitalis''. Resumen basado en el de la publicación Se dice que el futuro de un pueblo reside en sus hijos, y no sólo porque ellos son el futuro, sino porque este es mejor si protege y educa bien a sus niños. Ya en 1959 la Organización de las Naciones Unidas redactó diez principios en la Declaración de los Derechos del Niño. El segundo de estos principios afirma que 'el niño gozará de una protección especial para que pueda desarrollarse física, mental, moral, espiritual y socialmente'. En el siglo XXI, en un contexto de sociedad del conocimiento muy diferente al de 1959, el derecho a la protección deb…
