In this paper, a procedure for experimental optimization under safety constraints, to be denoted as constraint-aware Bayesian Optimization, is presented. The basic ingredients are a performance objective function and a constraint function; both of them will be modeled as Gaussian processes. We incorporate a prior model (transfer learning) used for the mean of the Gaussian processes, a semi-parametric Kernel, and acquisition function optimization under chance-constrained requirements. In this way, experimental fine-tuning of a performance objective under experiment-model mismatch can be safely carried out. The methodology is illustrated in a case study on a line-follower application in a CoppeliaSim environment.

UNMANNED aerial vehicles (UAVs), either multirotor or fixed-wing UAVs, can be used in many fields to solve complex problems in safety [1], communications [2, 3], military applications [4, 5], civilian applications [6, 7], protection of nuclear plants [8], energy efficiency [9], nonlinear control [10, 11], and path planning [12], among others. Vertical takeoff and landing (VTOL) is by far the most used UAV's configuration [13]. Probably the main reason is that, nowadays, there are lots of low-cost multirotor models. VTOL strategies can be applied to fixed-wing airplanes [14]; however, in normal operation they usually fly horizontally to keep a constant altitude [15, 16], but they need to perform changes in their heading and altitude very often, especially in cluttered environments [17].

Carpophores of Ganoderma lingzhi (GZ) from industrial crops in China were analysed and compared with carpophores of three Iberian strains of cultivated Ganoderma lucidum (GL) (Aveiro, Madrid, Palencia) previously genetically characterized. The genetic determination of all the fungi in the study coincided with the identification provided by the companies and entities that supplied the samples. Cultivation time ranged between 107 and 141 days. The analysis of total phenol content showed to be 56.8% higher for GL from Palencia than for GZ. Intraspecific variation was a maximum of 56% from GL. The content of antioxidants, both intraspecific and interspecific, was found to be strain-dependent with a maximum variation of 78.5%. The nutritional analysis shows that there are differences in dietary fiber, protein, ash and sodium content between GL and GZ. In fatty acids analysis, only trans fatty acids showed significant differences, being higher in GL. Protein profile and digestibility of GZ and GL-Madrid mushroom proteins were evaluated by digestion with simulated gastric fluid and were different. The two species were perfectly differentiated according to their protein profile. These results should be considered for nutritional and industrial applications.

Contact driven tasks, such as surface conditioning operations (wiping, polishing, sanding, etc.), are difficult to program in advance to be performed autonomously by a robotic system, specially when the objects involved are moving. In many applications, human-robot physical interaction can be used for the teaching, specially in learning from demonstrations frameworks, but this solution is not always available. Robot teleoperation is very useful when user and robot cannot share the same workspace due to hazardous environments, inaccessible locations, or because of ergonomic issues. In this sense, this article introduces a novel dual-arm teleoperation architecture with haptic and visual feedback to enhance the operator immersion in surface treatment tasks. Two task-based assistance systems are also proposed to control each robotic manipulator individually. To validate the remote assisted control, some usability tests have been carried out using Baxter, a dual-arm collaborative robot. After analysing several benchmark metrics, the results show that the proposed assistance method helps to reduce the task duration and improves the overall performance of the teleoperation.

[EN] The evaluation of a subject is a fundamental part of the teaching-learning process and one of the main concerns of our students. This is a complex task that requires a lot of effort from the teacher. This is a growing effort in line with the increased weight of con-tinuous evaluation in the current educational system. In this work, different methodo-logies focused on maximizing the student’s performance are presented, thus minimizing the extra effort for the teacher in the evaluation process. We provide several examples of activities throught Moodle platform such as the workshop, glossary, databases, ques-tionnaires, etc. Some of them allow self-assessment once configured, whereas others promote the participation of students in the correction and/or evaluation., [ES] La evaluación de una asignatura es una parte fundamental del proceso de enseñanza-aprendizaje y una de la que más preocupa a nuestros estudiantes. Se trata de una tarea compleja y que requiere un gran esfuerzo por parte del profesor.

[EN] In heavy-duty vehicles, multiple signals are available to estimate the vehicle's kinematics, such as Inertial Measurement Unit (IMU), Global Positioning System (GPS) and linear and angular speed readings from wheel tachometers on the internal Controller Area Network (CAN). These signals have different noise variance, bandwidth and sampling rate (being the latter, possibly, irregular). In this paper we present a non-linear sensor fusion algorithm allowing asynchronous sampling and non-causal smoothing. It is applied to achieve accuracy improvements when incorporating odometry measurements from CAN bus to standard GPS+IMU kinematic estimation, as well as the robustness against missing data. Our results show that this asynchronous multi-sensor (GPS+IMU+CAN-based odometry) fusion is advantageous in low-speed manoeuvres, improving accuracy and robustness to missing data, thanks to non-causal filtering. The proposed algorithm is based on Extended Kalman Filter and Smoother, with exponential discretization of continuous-time stochastic differential equations, in order to process measurements at arbitrary time instants; it can provide data to subsequent processing steps at arbitrary time instants, not necessarily coincident with the original measurement ones. Given the extra information available in the smoothing case, its estimation performance is less sensitive to the noise-variance parameter setting, compared to causal filtering. Working Matlab code is provided at the end of this work., This research was supported in part by the Agencia Espanola de Investigacion (European Union) under Grants PID2020-116585GB-I00 and PID2020-118071GB-I00, and in part by the Generalitat Valenciana under Grant GV/2021/074.

[EN] Surface treatment operations, such as sanding, deburring, finishing, grinding, polishing, etc. are progressively becoming more automated using robotic systems. However, previous research in this field used a completely automatic operation of the robot system or considered a low degree of human-robot interaction. Therefore, to overcome this issue, this work develops a truly synergistic cooperation between the human operator and the robot system to get the best from both. In particular, in the application developed in this work the human operator provides flexibility, guiding the tool of the robot system to treat arbitrary regions of the workpiece surface; while the robot system provides strength, accuracy and security, not only holding the tool and keeping the right tool orientation, but also guaranteeing a smooth approach to the workpiece and confining the tool within the allowed area close to the workpiece. Moreover, to add more flexibility to the proposed method, when the user is not guiding the robot tool, a robot automatic operation is activated to perform the treatment in prior established regions. Furthermore, a camera network is used to get a global view of the robot workspace in order to obtain the workpiece location accurately and in real-time. The effectiveness of the proposed approach is shown with several experiments using a 6R robotic arm., This research was founded by the Spanish Government and the Generalitat Valenciana under Grants PID2020-117421RB-C21, GV/2021/181 and ACIF/2019/007.

[EN] There are some industrial tasks that are still mainly performed manually by human workers due to their complexity, which is the case of surface treatment operations (such as sanding, deburring, finishing, grinding, polishing, etc.) used to repair defects. This work develops an advanced teleoperation and control system for industrial robots in order to assist the human operator to perform the mentioned tasks. On the one hand, the controlled robotic system provides strength and accuracy, holding the tool, keeping the right tool orientation and guaranteeing a smooth approach to the workpiece. On the other hand, the advanced teleoperation provides security and comfort to the user when performing the task. In particular, the proposed teleoperation uses augmented virtuality (i.e., a virtual world that includes non-modeled real-world data) and haptic feedback to provide the user an immersive virtual experience when remotely teleoperating the tool of the robot system to treat arbitrary regions of the workpiece surface. The method is illustrated with a car body surface treatment operation, although it can be easily extended to other surface treatment applications or even to other industrial tasks where the human operator may benefit from robotic assistance. The effectiveness of the proposed approach is shown with several experiments using a 6R robotic arm. Moreover, a comparison of the performance obtained manually by an expert and that obtained with the proposed method has also been conducted in order to show the suitability of the proposed approach., This research was founded by the Spanish Government and the Generalitat Valenciana under Grants PID2020-117421RB-C21 and GV/2021/005

- Abstract
[EN] The acquisition of programming and data analysis skills in higher education is increa-singly necessary in all areas of Science and Engineering. In this paper we present a methodology for the motivation of programming learning, mainly focused on the deve-lopment of machine learning algorithms. This methodology is based on the hackathon idea and will have different levels. On the one hand the basic level where a competition is proposed in an improvised way during the development of the class. A second level where a programmed hackathon is proposed but within the classroom environment and using learning management systems such as Moodle. The last level consists of parti-cipation in an external hackathon and the delivery of a report. These levels have been adapted and tested in several undergraduate and master’s degree courses at the Uni-versity of Valencia. We include detailed information on how the methodology has been adapted to the teaching needs of the subject and we conducted anonymized surveys to students to know their degree of satisfaction. These surveys reveal a positive assessment of the experience by the students and include constructive comments for improvement in future editions., [ES] Se presenta una metodología para la motivación del aprendizaje de programación, principalmente enfocada al desarrollo de algoritmos de machine learning. Esta metodología está basada en la idea de hackathon o datathon y tendrá distintos niveles. Por un lado el nivel básico donde se plantea una competición de forma improvisada durante el desarrollo de la clase. Este nivel se puede utilizar para motivar, la evaluación tiene que restringirse a la mera participación. Un segundo nivel donde se plantea un hackathon programado pero dentro del entorno de la clase y utilizando sistemas de gestión de aprendizaje tipo Moodle. Este nivel se puede utilizar para evaluación tanto durante la clase como para un examen. El último nivel consiste en la participación en un hackathon externo y la entrega de un informe. Esta metodología puede servir para la evaluación de una tarea de clase y fomentar el trabajo en equipo. Además plantea un problema real en un entorno semi-profesional.

- Abstract
[EN] The evaluation of a subject is a fundamental part of the teaching-learning process and one of the main concerns of our students. This is a complex task that requires a lot of effort from the teacher. This is a growing effort in line with the increased weight of con-tinuous evaluation in the current educational system. In this work, different methodo-logies focused on maximizing the student’s performance are presented, thus minimizing the extra effort for the teacher in the evaluation process. We provide several examples of activities throught Moodle platform such as the workshop, glossary, databases, ques-tionnaires, etc. Some of them allow self-assessment once configured, whereas others promote the participation of students in the correction and/or evaluation., [ES] La evaluación de una asignatura es una parte fundamental del proceso de enseñanza-aprendizaje y una de la que más preocupa a nuestros estudiantes.

- Abstract
[EN] There are some industrial tasks that are still mainly performed manually by human workers due to their complexity, which is the case of surface treatment operations (such as sanding, deburring, finishing, grinding, polishing, etc.) used to repair defects. This work develops an advanced teleoperation and control system for industrial robots in order to assist the human operator to perform the mentioned tasks. On the one hand, the controlled robotic system provides strength and accuracy, holding the tool, keeping the right tool orientation and guaranteeing a smooth approach to the workpiece. On the other hand, the advanced teleoperation provides security and comfort to the user when performing the task. In particular, the proposed teleoperation uses augmented virtuality (i.e., a virtual world that includes non-modeled real-world data) and haptic feedback to provide the user an immersive virtual experience when remotely teleoperating the tool of the robot system to treat arbitrary regions of the workpiece surface. The method is illustrated with a car body surface treatment operation, although it can be easily extended to other surface treatment applications or even to other industrial tasks where the human operator may benefit from robotic assistance. The effectiveness of the proposed approach is shown with several experiments using a 6R robotic arm. Moreover, a comparison of the performance obtained manually by an expert and that obtained with the proposed method has also been conducted in order to show the suitability of the proposed approach.

- Abstract
[EN] Surface treatment operations, such as sanding, deburring, finishing, grinding, polishing, etc. are progressively becoming more automated using robotic systems. However, previous research in this field used a completely automatic operation of the robot system or considered a low degree of human-robot interaction. Therefore, to overcome this issue, this work develops a truly synergistic cooperation between the human operator and the robot system to get the best from both. In particular, in the application developed in this work the human operator provides flexibility, guiding the tool of the robot system to treat arbitrary regions of the workpiece surface; while the robot system provides strength, accuracy and security, not only holding the tool and keeping the right tool orientation, but also guaranteeing a smooth approach to the workpiece and confining the tool within the allowed area close to the workpiece. Moreover, to add more flexibility to the proposed method, when the user is not guiding the robot tool, a robot automatic operation is activated to perform the treatment in prior established regions. Furthermore, a camera network is used to get a global view of the robot workspace in order to obtain the workpiece location accurately and in real-time. The effectiveness of the proposed approach is shown with several experiments using a 6R robotic arm.

- Abstract
[EN] The Directive (EU) 2015/653 aimed at facilitating that the maximum force that any disabled driver could make on the vehicle's primary controls could be adjusted to their needs. The technical adjustment in the vehicle's design requires a measurement of the operational forces applied by the driver on the steering and brake controls, in order to determine its functional capacity during the execution of driving maneuvers. The objective of this paper is to define the steering and braking operative forces used for driving current market M1 motor vehicles for the ¿fitness to drive assessment of drivers with physical disabilities. A total of 200 trials were performed with 17 different vehicles and 26 drivers. The results obtained help to define a new threshold's criteria for operative forces onto the steering and braking systems for adapting motor vehicles to disabled drivers. The main contribution of this paper consist on a new technical recommendations about the use of code 20.07 -braking- and 40.01 -steering- to be used in the ¿fitness to drive assessment of driver with disabilities according to Directive (EU) 2015/653 requirements.

- Abstract
Siguiendo un patrón de alimentación saludable, diariamente consumimos alimentos del mundo vegetal llenos de compuestos bioactivos que nuestro organismo es capaz de metabolizar y sacar beneficio de ellos. Sin embargo, al consumir partes de plantas también ingerimos compuestos y sustancias que puede que no siempre tengan un efecto beneficioso, como aquellos que se comportan como inhibidores de las funciones enzimáticas de nuestro organismo. Los inhibidores de enzimas digestivas (de hidratos de carbono y de proteínas) están muy presentes en vegetales y plantas de consumo e interfieren en el proceso de digestión. Las plantas contienen también otras sustancias que se comportan como tóxicos, entre ellas las lectinas. Estas substancias tienen especial relevancia para aquellas personas que lleven una dieta muy rica en vegetales o incluso vegana , cada vez más de moda entre la población, de ahí la necesidad de conocer las correctas formas de preparación culinaria para evitar posibles efectos adversos., Grado en Nutrición Humana y Dietética

- Abstract
El calcio es un mineral esencial necesario para el correcto mantenimiento de la salud ósea a lo largo de todo el ciclo vital del ser humano. En la revisión realizada en este estudio se ha visto que en España la ingesta dietética de calcio es insuficiente en ciertos rangos de edad como son la población adolescente (10-19 años) y en los mayores de 60 años. Existe evidencia de que el uso de declaraciones de propiedades saludables (DS) mejora la calidad de las elecciones dietéticas y el conocimiento de la relación dieta-enfermedad. Por su parte, la industria alimentaria desarrolla alimentos funcionales (FF) con DS con el fin de optimizar la salud de los consumidores y la EFSA junto con la Comisión Europea se encargan de establecer los requisitos y el marco legal para asegurar la protección al consumidor. Es evidente que el desarrollo de FF debe ir acompañado de la aplicación de controles adecuados y seguimiento para garantizar que las DS se utilicen para obtener su mejor efecto en la promoción de la salud pública y la protección del consumidor frente a información engañosa. A pesar de estas garantías, el consumo de los FF con DS depende en gran medida de la percepción del consumidor. Por ello el objetivo de esta tesis, tras conocer la ingesta dietética de Ca en España, ha sido elaborar modelos predictivos de consumo de los alimentos lácteos enriquecidos en Ca en función de la percepción de las DS que llevan en su etiquetado en una muestra de la Comunidad Universitaria de la Universidad de Valladolid (CUVa). Para alcanzar los objetivos propuestos se realizó una revisión bibliográfica y un estudio cuantitativo, observacional y prospectivo con diseño de encuesta transversal analítica a 1261 personas pertenecientes a todos los colectivos de la CUVa en 2019. Con los datos obtenidos a partir de las encuestas se han desarrollado tres modelos predictivos para dos alimentos funcionales con DS relacionadas con el Ca, correspondientes a la intención de compra, compra e ingesta de, Departamento de Anatomía Patológica, Microbiología, Medicina Preventiva y Salud Pública, Medicina Legal y Forense, Doctorado en Investigación en Ciencias de la Salud

- Abstract
Las lectinas son proteínas fijadoras de glicosaminoglicanos (CBPs) capaces de reconocer carbohidratos de manera altamente específica, reversible y sin modificar su estructura, a través de los dominios de reconocimiento de carbohidratos. En el ámbito de la Farmacia Galénica estas proteínas se están empleando entre otros usos, para dirigir de manera altamente específica, fármacos o sistemas micro o nanoparticulares a la superficie glicosilada de ciertos tejidos (reverse lectin targeting) [1]. La SELfd es una lectina dimérica aislada de frutos de Sambucus ebulus L. con una gran afinidad por restos L-fucosa, D-(+)- galactosa, N-acetil-Dglucosamina, y N- acetil-D-galactosamina. Estos carbohidratos se encuentran sobreexpresados en los bordes apicales de las membranas glicoproteicas de las células M de las placas de Peyer, ciertos tumores o en tejido intestinal inflamado. El objetivo del presente estudio consiste en evaluar la especificidad de dicha proteína por tejido inflamado en un modelo reversible de daño-regeneración intestinal para determinar si dicha proteína podría emplearse en sistemas de vectorización en patologías tipo Crohn.

- Abstract
La presente revisión es un estudio completo de la soja (glycine max) con varias partes diferenciadas. Primero, introduce a la soja contextualmente, definiéndola y explicando además su composición nutricional, usos e impacto en las sociedades consumidoras como alimento funcional. Se definirán algunos de sus derivados y fermentados más comunes y los beneficios que estos últimos nos pueden aportar. Entre estos efectos se encuentran la mejora del sistema inmune, su uso como antioxidantes o el aumento de la densidad ósea, entre otros. A continuación, se tratarán algunos de sus componentes más importantes, empezando por las isoflavonas, que podrían ser muy interesantes de cara al estudio y la prevención de algunas enfermedades crónicas, así como su importancia en la inflamación y su uso para paliar algunos síntomas de la menopausia. También es muy importante el contenido en antinutrientes de la soja: por lo que se hablará de algunos de los más importantes: lectinas con dominio de leguminosas, inhibidor de α-amilasa y ácido fítico; definiéndolos y explicando sus funciones inhibitorias de la correcta digestión de algunos nutrientes. Dentro del grupo de los inhibidores de proteasas, se pondrá especial atención en los inhibidores de tripsina (inhibidores de Bowman-Birk y Kunitz); por lo que se explicará su funcionamiento, algunas de sus características principales, los beneficios que nos aportan en ciertas dosis y las mecánicas de inactivación que estos sufren tras el cocinado debido a su desnaturalización. A pesar de todos los posibles beneficios de este alimento, no se debería consumir soja de manera excesiva, pues podría derivar en problemas como la interferencia con medicamentos o problemas nutricionales como por ejemplo el déficit de nutrientes. Este problema se vería amplificado en el caso de los niños que usan la bebida de soja para sustituir la leche, afectando a su desarrollo., Grado en Nutrición Humana y Dietética

- Abstract
El presente estudio evalúa la evidencia de la efectividad del inhibidor de la α-amilasa extraído de la judía común (Phaseolus vulgaris) por su potencial uso como tratamiento de la obesidad y diabetes. Examina, además, sus propiedades estructurales y los factores que afectan a su actividad, y los efectos adversos derivados de su utilización. Su estructura y sus propiedades fisicoquímicas facilitan la inhibición de la enzima α-amilasa lo cual dificulta la conversión de hidratos de carbono complejos a azúcares simples y contribuye a una menor absorción de energía y una disminución de la glucemia postprandial. También es considerado como posible ingrediente en los alimentos para aumentar la tolerancia a los hidratos de carbono en personas diabéticas, así como poder reducir la obesidad. La evidencia es insuficiente para establecer una relación causal entre el consumo de este componente de la judía común y un efecto fisiológico beneficioso, ni para asegurar la seguridad de su uso en humanos., Grado en Nutrición Humana y Dietética

Background The wastes of pecan nut (Carya illinoinensis (Wangenh.) K. Koch) production are increasing worldwide and have high concentrations of tannins and phenols. Aims To study the biodegradation of lignocellulosic wastes of pecan used as solid substrate for the cultivation of the white-rot fungus Ganoderma lucidum (Curtis) P. Karst. Methods Six formulations of pecan wastes were used as solid substrate: pecan shells (PS100), pecan pericarp (PP100), pecan wood-chips (PB100), and the combinations PS50 + PP50, PB50 + PS50 and PB50 + PP50. The substrates were inoculated with a wild strain of G. lucidum collected in the Iberian Peninsula. The biodegradation capability of G. lucidum was estimated by using the mycelial growth rate, the biological efficiency, the production and the dry biological efficiency. Results Notably, all solid substrates were suitable for G. lucidum growth and mushroom yield. The best performance in mushroom yield was obtained with PB100 (55.4% BE), followed by PB50 + PP50 (31.7% BE) and PB50 + PS50 (25.4% BE). The mushroom yield in the substrates containing pecan wood-chips (PB) was significantly higher. Conclusions Our study is leading the way in attempting the cultivation of G. lucidum on lignocellulosic pecan waste. These results show an environmentally friendly alternative that increases the benefits for the global pecan industry, especially in rural areas, and transforms biomass into mushrooms with nutraceutical properties and biotechnological applications.

This work develops a method to perform surface treatment tasks using a bimanual robotic system, i.e. two robot arms cooperatively performing the task. In particular, one robot arm holds the workpiece while the other robot arm has the treatment tool attached to its end-effector. Moreover, the human user teleoperates all the six coordinates of the former robot arm and two coordinates of the latter robot arm, i.e. the teleoperator can move the treatment tool on the plane given by the workpiece surface. Furthermore, a force sensor attached to the treatment tool is used to automatically attain the desired pressure between the tool and the workpiece and to automatically keep the tool orientation orthogonal to the workpiece surface. In addition, to assist the human user during the teleoperation, several constraints are defined for both robot arms in order to avoid exceeding the allowed workspace, e.g. to avoid collisions with other objects in the environment. The theory used in this work to develop the bimanual robot control relies on sliding mode control and task prioritisation. Finally, the feasibility and effectiveness of the method are shown through experimental results using two robot arms. [ABSTRACT FROM AUTHOR]
