A radio channel model for D2D communications blocked by single trees in forest environments
In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ... -
Radio characterization for ISM 2.4 GHz wireless sensor networks for judo monitoring applications
In this work, the characterization of the radio channel for ISM 2.4GHz Wireless Sensor Networks (WSNs) for judo applications is presented. The environments where judo activity is held are usually complex indoor scenarios ... -
Radio wave propagation and WSN deployment in complex utility tunnel environments
The significant growth of wireless communications systems in the last years has led to the adoption of a wide range of applications not only for the general public but, also, including utilities and administrative authorities. ... -
Radiología innecesaria en Atención Primaria
Fundamento: La solicitud de pruebas diagnósticas desde atención primaria presentan un aumento progresivo en el tiempo y una gran variabilidad interpersonal en su solicitud, que sugiere que se están aplicando servicios ... -
Raising the accuracy of shadow economy measurements
En este artículo se estima el tamaño de la economía sumergida en una región española (Navarra) para el período 1986-2016. Se han empleado métodos macroeconométricos indirectos, como el enfoque de Demanda de efectivo, dos ... -
Random DFB fiber laser for remote (200 km) sensor monitoring using hybrid WDM/TDM
In this paper, a random distributed feedback fiber laser is proposed as a multiplexing scheme for ultralong range measurements (up to 200 km). Optical fiber sensors are time and wavelength multiplexed overcoming one of the ... -
Random subwavelength structures on glass to improve photovoltaic module performance
Glass samples have been processed by a single-step self-masking RIE (Reactive Ion Etching) process to obtain random subwavelength structures (SWSs), which mimic anti-reflective and anti-soiling patterns present in nature. ... -
Ranking opportunity profiles through dependent evaluation of policies
Rankings to evaluate opportunity distributions present in most of the literature judge a policy (change from one distribution of opportunities to another) on the basis of the changes created and, thus, independently ... -
Ransomware early detection by the analysis of file sharing traffic
Crypto ransomware is a type of malware that locks access to user files by encrypting them and demands a ransom in order to obtain the decryption key. This type of malware has become a serious threat for most enterprises. ... -
Rara avis: Latin American populism in the 21st century
Since the beginning of the 21st century, many Latin American countries have been ruled by governments characterized as populist (the so-called new Latin American Left). We focus on the macroeconomic implications of the ... -
Rasgos comunes entre el poder punitivo y el poder patriarcal
El poder punitivo manifestado especialmente en la existencia y el uso de las prisiones, pero expresión también del castigo en general (en la relación consigo misma y las demás personas, en la familia, la escuela, las ... -
Raw-cured Spanish traditional meat product 'Chistorra de Navarra': sensory and composition quality standards
The aim of this work was to set the quality standards of the chistorra de Navarra, a raw-cured Spanish traditional meat product, through the study of its sensory and physicochemical features. The quality of chistorra ... -
A ray launching-neural network approach for radio wave propagation analysis in complex indoor environments
A novel deterministic approach to model the radio wave propagation channels in complex indoor environments reducing computational complexity is proposed. This technique combines a neural network and a 3D ray launching ... -
Razón y cultura: una crítica a la hermenéutica constitucional moderna desde la interpretación dialógica
A través del análisis crítico de la teoría de la interpretación entendida como límite a los poderes de los últimos intérpretes de la Constitución, este trabajo intenta evidenciar la inexistencia, por una parte, de algunos ... -
Razonamiento inductivo, inteligencia y aprendizaje
Razonar inductivamente es aportar más información que la que ofrecen las premisas. La elaboración de inferencias a partir de categorías, de descubrimiento de causas, de averiguación de efectos y de cálculo de probabilidades son ... -
Razones para el abandono del tratamiento en comunidad terapéutica
Objetivo: en este estudio se analizan las razones o motivos del abandono del tratamiento en la Comunidad Terapéutica de Proyecto Hombre de Navarra. Material y métodos: se cuenta con una muestra de 61 pacientes que, tras ... -

Introducción: las razones que motivan a estudiar medicina o enfermería, y el cumplimiento de las expectativas profesionales, son los factores que determinan el volver a realizar los mismos estudios. El objetivo de este ... -
The RD-connect genome-phenome analysis platform: accelerating diagnosis, research, and gene discovery for rare diseases
Rare disease patients are more likely to receive a rapid molecular diagnosis nowadays thanks to the wide adoption of next-generation sequencing. However, many cases remain undiagnosed even after exome or genome analysis, ... -
Reaction monitoring by ultrasounds in a pseudohomogeneous medium: triglyceride ethanolysis for biodiesel production
The sound propagation speed measurement us is used for monitoring triglyceride ethanol-ysis in a broad range of reaction conditions (mainly, temperature: 23–50◦C; ethanol/oil: from 6 to 24 mol/mol). Experimentally, us ... -
Real elements and p-nilpotence of finite groups
Our first main result proves that every element of order 4 of a Sylow 2-subgroup S of a minimal non-2-nilpotent group G, is a real element of S. This allows to give a character-free proof of a theorem due to Isaacs and ...
