The growth of sensor networks during the last years is a fact and within this field, wireless sensor networks are growing particularly as there are many applications that demand the use of many nodes, even hundreds or thousands. More and more applications are emerging to solve several problems in data acquisition and control in different environments,(More)
— A new orientation for a multidisciplinary Industrial Engineering program course on Digital Electronics is proposed. Students are trained to describe complete systems in VHDL. These systems have been previously modeled with Matlab/Simulink ®, including both continuous and discrete components. Digital controllers based on concurrent hardware are designed(More)
The fractures of the scapula are not very frequent, an incidence around the 0,4 and 1% of the fractures that affect the upper limb. The acromion fracture means the 7% of the fractures that affect to the scapula. They usually appear in politraumatized patients with more serious lesions that can mask them and postpose this way their diagnosis and treatment.(More)
The goal of this work is to determine whether relationship power in couples and sexual double standard can predict the risk of sexually transmitted infections/human immunodeficiency virus (STI/HIV) as a function of cultural and gender differences. The sample was made up of 689 adolescents living in Spain, of both sexes, aged between 14 and 19 years, who(More)
Sensor networks have reached a great relevance during the last years. The idea is to use a high number of nodes measuring different physical parameters in several environments, which implies different research challenges (low power consumption, communication protocols, platform hardware design, etc). There is a tendency to use modular hardware nodes in(More)
In this paper we study the heat transfer with a general fractional diffusion term of an incompressible fluid in a porous medium governed by Darcy’s law. We show formation of singularities with infinite energy and for finite energy we obtain existence and uniqueness results of strong solutions for the sub-critical and critical cases. We prove global(More)
Wireless sensor networks (WSNs) have become widely relevant in recent years, facilitating data collection through a large number of nodes measuring different physical parameters in various environments. Such networks require low power consumption in the individual sensors and adequate protocols for communication between the nodes. Effective platform(More)
The goal of this study was to analyze how worry about sexually-transmitted infections (STI) and HIV influences attitudes and self-efficacy towards condom use, HIV-related knowledge, HIV-perceived susceptibility and HIV-misconceptions in a multicultural sample in Spain. The sample was composed of 3,051 adolescents aged between 14 and 19 years old who lived(More)
