Healing, knowing, enduring: Care and politics in damaged worlds
How can politics be articulated or at least imagined by ill, impoverished and abandoned communities? This article documents how care is invoked by activist groups and local citizens in their search for ethical recognition ...
La reactivació del Tribunal de Contrafaccions de Catalunya durant la guerra
El Tribunal de Contrafaccions fou una institució mixta i paritària, formada per tres jutges de part de la monarquia i tres de part dels braços de la Cort de Catalunya. La seva missió fou defensar a escala suprema, per sobre ...

The team orienteering problem with stochastic service times and driving-range limitations: A simheuristic approach
In the context of smart cities, unmanned aerial vehicles (UAVs) offer an alternative way of gathering data and delivering products. On the one hand, in congested urban areas UAVs might represent a faster way of performing ...
Anonymous reputation based reservations in e-commerce (AMNESIC)
Online reservation systems have grown over the last recent years to facilitate the purchase of goods and services. Generally, reservation systems require that customers provide some personal data to make a reservation ...
Prova: visualizzazione vocabolari alternativi nell'O2 repo UOC
This paper reviews the existing methodologies and best practices for digital investigations phases like collecting metadata
Experiencia de gamificación en secundaria en el aprendizaje de sistemas digitales
El uso del juego, utilizado siempre en edades tempranas para motivar el aprendizaje, ha sido frecuentemente estigmatizado en edades más avanzadas al considerarse una pérdida de tiempo. Sin embargo, en los últimos años el ...
On the use of learnheuristics in vehicle routing optimization problems with dynamic inputs
Freight transportation is becoming an increasingly critical activity for enterprises in a global world. Moreover, the distribution activities have a non-negligible impact on the environment, as well as on the citizens' ...
Dynamic pricing for vehicle ferries: using packing and simulation to optimize revenues
We propose an improved heuristic approach to the vehicle ferry revenue management problem, where the aim is to maximize the revenue obtained from the sale of vehicle tickets by varying the prices charged to different vehicle ...
Preferred spatial frequencies for human face processing are associated with optimal class discrimination in the machine
Psychophysical studies suggest that humans preferentially use a narrow band of low spatial frequencies for face recognition. Here we asked whether artificial face recognition systems have an improved recognition performance ...
Enhanced multi-directional local search for the bi-objective heterogeneous vehicle routing problem with multiple driving ranges
The transportation sector accounts for a significant amount of greenhouse gas emissions. To mitigate this problem, electric vehicles have been widely recommended as green vehicles with lower emissions. However, the driving ...
Subjectively adapted high capacity lossless image data hiding based on prediction errors
This article reports on a lossless data hiding scheme for digital images where the data hiding capacity is either determined by minimum acceptable subjective quality or by the demanded capacity. In the proposed method data ...

Off-Line Evaluation of Mobile-Centric Indoor Positioning Systems: The Experiences from the 2017 IPIN Competition
The development of indoor positioning solutions using smartphones is a growing activity with an enormous potential for everyday life and professional applications. The research activities on this topic concentrate on the ...
Lightweight and static verification of UML executable models
Executable models play a key role in many software development methods by facilitating the (semi)automatic implementation/execution of the software system under development. This is possible because executable models promote ...
Using simulation to estimate critical paths and survival functions in aircraft turnaround processes
In the context of aircraft turnaround processes, this paper illustrates how simulation can be used not only to analyze critical activities and paths, but also to generate the associated survival functions ' thus providing ...
Diffusive and arrestedlike dynamics in currency exchange markets
This work studies the symmetry between colloidal dynamics and the dynamics of the Euro-U.S. dollar currency exchange market (EURUSD). We consider the EURUSD price in the time range between 2001 and 2015, where we find ...
