A cognitive-radio-based method for improving availability in body sensor networks
One of the main threats to body sensor networks (BSNs) is denial of service attacks that disrupt communications used to transmit patients' health data. The application of cognitive radio (CR) technology into BSNs can ...
Statistical and machine learning approaches for the minimization of trigger errors in earthquake catastrophe bonds
Catastrophe bonds are financial instruments designed to transfer risk of monetary losses arising from earthquakes, hurricanes, or floods to the capital markets. The insurance and reinsurance industry, governments, and ...
Editorial of special issue on: Applications of risk analysis and analytics in engineering and economics
In areas such as engineering, economics, and insurance, real-world systems are becoming increasingly complex to analyse due to their global scale as well as to the uncertainty and dynamic conditions that characterises ...
Individual differential privacy: A utility-preserving formulation of differential privacy guarantees
Differential privacy is a popular privacy model within the research community because of the strong privacy guarantee it offers, namely that the presence or absence of any individual in a data set does not significantly ...
Accurate clock discipline for long-term synchronization intervals
Efficient spectrum usage and optimized energy consumption directly depend on the radio duty cycle of the communicating devices. Tight synchronization of communicating nodes enables optimal orchestration of the access to ...
UMLtoGraphDB: Mapping conceptual schemas to graph databases
The need to store and manipulate large volume of (unstructured) data has led to the development of several NoSQL databases for better scalability. Graph databases are a particular kind of NoSQL databases that have proven ...
¿Tiene sentido una intervención rehabilitadora con internos no motivados al cambio?
Treball de Fi de Grau en Criminologia i Polítiques Públiques de Prevenció. Curs 2012-2013/n Tutor: Antoni Forcadell Berenguer
Measuring Systems and Architectures: A Sustainability Perspective
This issue's Practioners' Digest column reports on the 2018 Measurement and Metrics for Green and Sustainable Software Systems Workshop (MeGSuS), the ACM/IEEE 21st International Conference on Model Driven Engineering ...
On the use of biased-randomized algorithms for solving non-smooth optimization problems
Soft constraints are quite common in real-life applications. For example, in freight transportation, the fleet size can be enlarged by outsourcing part of the distribution service and some deliveries to customers can be ...
Combining Monte Carlo simulation with heuristics to solve a rich and real-life multi-depot vehicle routing problem
This paper presents an optimization approach which integrates Monte Carlo simulation (MCS) within a heuristic algorithm in order to deal with a rich and real-life vehicle routing problem. A set of customers' orders must ...
Synthetic generation of spatial graphs
Graphs can be used to model many different types of interaction networks, for example, online social networks or animal transport networks. Several algorithms have thus been introduced to build graphs according to some ...
Responsible research and innovation indicators for science education assessment: how to measure the impact?
The emerging paradigm of responsible research and innovation (RRI) in the European Commission policy discourse identifies science education as a key agenda for better equipping students with skills and knowledge to tackle ...
Adaptive e-assessment system: A general approach
On any type of course (on site or online), a learner is evaluated whether he has acquired the knowledge and competences provided in the course. The evaluation should be performed by evaluating his progression by means of ...
J-SAEDES: A Java-based simulation software to improve reliability and availability of computer systems and networks
Nowadays, many companies rely on computer systems and networks for functions such as order entry, customer support, supply chain management, and employee administration. Therefore, reliability and availability of such ...
A Petri Nets-based Scheduling Methodology forMultipurpose Batch Plants.
This article presents an optimization methodology of batch production processes assembled by shared resources which rely on a mapping of state-events into time-events allowing in this way the straightforward use of a well ...
Scheduling airline reserve crew using a probabilistic crew absence and recovery model
Airlines require reserve crew to replace delayed or absent crew, with the aim of preventing consequent flight cancellations. A reserve crew schedule specifies the duty periods for which different reserve crew will be on ...
Enabling SDN in VANETs: What is the impact on security?
The demand for safe and secure journeys over roads and highways has been growing at a tremendous pace over recent decades. At the same time, the smart city paradigm has emerged to improve citizens' quality of life by ...
