Classification of Targets Using Statistical Features from Range FFT of mmWave FMCW Radars
2021
Radars with mmWave frequency modulated continuous wave (FMCW) technology accurately estimate the range and velocity of targets in their field of view (FoV). The targeted angle of arrival (AoA) estimation can be improved by increasing receiving antennas or by using multiple-input multiple-output (MIMO). However, obtaining target features such as target type remains challenging. In this paper, we present a novel target classification method based on machine learning and features extracted from a range fast Fourier transform (FFT) profile by using mmWave FMCW radars operating in the frequency range of 77–81 GHz. The measurements are carried out in a variety of realistic situations, including p…
Automatic Generation of User Interfaces using the Set Description Language
2004
We present a paradigm to generate automatically graphical user interfaces from a formal description of the data model following the well-known model-view-control paradigm. This paradigm provide complete separation between data model and interface description, setting the programmer free from the low-level aspects of programming interfaces, letting him take care of higher level aspects. The interface along with the data model is described by means of a formal language, the Set Description Language. We also describe the infrastructure based on this paradigm we implemented to generate graphical user interfaces for generic applications. Moreover, it can adapt the user interface of a program to …

Non-Linear Inductor Models Comparison for Switched-Mode Power Supplies Applications
2022
The use of non-linear power inductors, intended as devices exploited up to a current at which the inductance is halved, is of great interest in switched-mode power supplies (SMPSs). Indeed, it allows the use of lighter and cheaper inductors improving the power density. On the other hand, the analysis of SMPSs equipped with non-linear inductors requires appropriate modeling of the inductor reproducing the inductance versus current. This paper compares two main analytical models proposed in the literature: the former is based on a polynomial, and the latter exploits the arctangent function to reproduce the non-linearity of the inductance. Performance is compared by considering the effort of r…
El control de la comprensión de textos científicos en inglés como lengua extranjera, en estudiantes universitarios españoles no bilingües : evaluació…
2013
'Esta tesis presenta un estudio sobre el uso de estrategias metacognitivas y su impacto en la comprensión lectora en inglés como LE de estudiantes universitarios españoles. Se analiza dónde se encuentran las deficiencias, en su caso, y cómo pueden ser superadas mediante intervenciones didácticas apropiadas. Los estudios empíricos realizados se agrupan en tres grandes bloques. El primer bloque está dedicado a la caracterización de los estudiantes universitarios en lo que respecta a su competencia lectora en inglés. Un primer estudio evalúa el dominio lingüístico en inglés y las principales dificultades que presentan estos estudiantes para poder comunicar y comprender ideas básicas en esta le…
Identification et caractérisation de candidats d’origine naturelle à action herbicide pour contrôler les adventices
2016
EASPEIPMGESTADAGROSUPINRA; The use of herbicides to control weeds is very common. However, some herbicides are both environmentally detrimental and human unhealthy. The use of microorganisms acting as natural herbicide could be an alternative control method. Symptomatic weeds will be collected in field. Microorganisms will be isolated from symptomatic weeds, purified, identified and inoculated on weeds to confirm Koch’s postulates. The identified pathogenic microorganisms will be tested against a selection of weeds and crops to characterize the host range and the specificity of these microorganisms. In parallel, the diversity of endophytic microorganisms of symptomatic weeds will be charact…
La imagen de las mujeres en la polémica sobre el lujo (siglo XVIII)
1996
En los escritos de las ilustradas hallamos, desde diferentes posturas sociales y culturales, reacciones, unas frontales y otras interpretables como matizaciones, contra la secular culpabilización de las mujeres en los hábitos suntuarios, que nos proporcionan un ángulo más en la diversidad de pensamiento de la Ilustración.
Poesía satírica y crítica de costumbres en el Diario de Valencia (1790-1800)
1993
A partir del análisis de los numerosos poemas satíricos publicados en el Diario de Valencian durante su primera década de vida (1790-1800), se aprecia el intenso esfuerzo de reforma de las costumbres característico del siglo XVIII y se sistematizan sus principales preocupaciones y objetivos
Affect in the Context of Self-Determination Theory
2018
Self-determination theory has been applied to understand the role of affect in motivation and behavior in health contexts. According to self-determination theory, autonomous forms of motivation, reflecting self-endorsed reasons for acting and the satisfaction of psychological needs, are related to participation and persistence in health behavior. Research examining the role of affect in determining health behavior from the perspective of the theory is relatively sparse. Affect has served as both an outcome and process in applications of the theory to health behavior. Positive affect and psychological well-being have been identified as important outcomes of participating in behaviors for aut…
Readers’ Theater Projects for Special Education : A Randomized Controlled Study
2022
A randomized controlled trial was conducted to study the effectiveness of two readers’ theater (RT) programs in promoting reading skills and motivation of dysfluent readers in Grades 3–4. One program (RT Goal) included a goal of preparing a performance for an audience (n = 50), while another program (RT Practice) did not include such a goal (n = 49). A group of dysfluent readers receiving traditional oral reading intervention (Control group; n = 59) and a group of classroom peers (Mainstream group; n = 159) served as controls. The results indicate that both RT groups and the Control group developed at a higher rate in oral reading speed during the intervention period than the Mainstream gro…
