Industry 4.0 (the Fourth Industrial Revolution) is a concept devised for improving the operation of modern factories through the use of the latest technologies, under paradigms such as the Industrial Internet of Things (IIoT) or Big Data. One of such technologies is Blockchain, which is able to provide industrial processes with security, trust, tra...

Cryptocurrencies are fungible digital assets whose market capitalization has not stopped growing since the appearance of their first use case in 2009, Bitcoin. However, one of the biggest problems facing cryptocurrencies is the enormous fluctuation of their value in the market. To help understand different patterns in cryptocurrency ecosystems, sev...

Artificial intelligence algorithms, developed for traditional computing, based on Von Neumann’s architecture, are slow and expensive in terms of computational resources. Quantum mechanics has opened up a new world of possibilities within this field, since, thanks to the basic properties of a quantum computer, a great degree of parallelism can be ac...

This paper proposes a machine learning approach dealing with genetic programming to build classifiers through logical rule induction. In this context, we define and test a set of mutation operators across from different clinical datasets to improve the performance of the proposal for each dataset. The use of genetic programming for rule induction h...

Logistics services involve a wide range of transport operations between distributors and clients. Currently, the large number of intermediaries are a challenge for this sector, as it makes all the processes more complicated. To face that problem, we propose a system that uses smart contracts to remove intermediaries and speed up logistics activitie...

The lack of transparency is one of the problems affecting public tendering processes.
