SOUND SYNTHESIS WITH CELLULAR AUTOMATA

This thesis reports on new music technology research which investigates the use of cellular automata (CA) for the digital synthesis of dynamic sounds. The research addresses the problem of the sound design limitations of synthesis techniques based on CA. These limitations fundamentally stem from the unpredictable and autonomous nature of these computational models. Therefore, the aim of this thesis is to develop a sound synthesis technique based on CA capable of allowing a sound design process. A critical analysis of previous research in this area will be presented in order to justify that this problem has not been previously solved. Also, it will be discussed why this problem is worthwhile to solve. In order to achieve such aim, a novel approach is proposed which considers the output of CA as digital signals and uses DSP procedures to analyse them. This approach opens a large variety of possibilities for better understanding the self-organization process of CA with a view to identifying not only mapping possibilities for making the synthesis of sounds possible, but also control possibilities which enable a sound design process. As a result of this approach, this thesis presents a technique called Histogram Mapping Synthesis (HMS), which is based on the statistical analysis of CA evolutions by histogram measurements. HMS will be studied with four different automatons, and a considerable number of control mechanisms will be presented. These will show that HMS enables a reasonable sound design process. With these control mechanisms it is possible to design and produce in a predictable and controllable manner a variety of timbres. Some of these timbres are imitations of sounds produced by acoustic means and others are novel. All the sounds obtained present dynamic features and many of them, including some of those that are novel, retain important characteristics of sounds produced by acoustic means

Soplar las Velas. De gesto a rito.

[ES] Este TFG surge del análisis de algunos comportamientos y acciones que se generan entorno a la mesa; de entre éstos, nos centramos en el gesto de soplar las velas de cumpleaños. Un acto simple, instantáneo, banal y repetido por todos al menos una vez al año. Un gesto capturado a menudo en instantáneas familiares que nos muestran tanto el entorno social como la etapa vital en la que se encuentra cada individuo. Abordamos esta temática a través de diversas piezas que partiendo de la imagen de archivo, y la exploración de diferentes técnicas como la fotografía, la cianotipia, se materializan en un libro de artista y varias propuestas instalativas.[EN] This TFG arises from the analysis of some behaviors and actions that are generated around the table; among these, we focus on the gesture of blowing the birthday candles. A simple, instantaneous, banal act, repeated by everyone once a year. A gesture often captured in family snapshots that show us both the social environment and the vital stage in which each individual is. We approach this theme through various pieces that starting from the archive image, and the exploration of different techniques such as painting, photography, cyanotype, are materialized in an artist¿s book and several installation proposals.Fuster Serquera, R.

Soundcool Project: Collaborative Music Creation

[EN] This paper addresses four criteria that the Soundcool project meets: to "be sustainable", "be future-oriented", "be transformative" and "be innovative". Soundcool is a pedagogical and technological project. A brief description of the technology behind Soundcool will be useful for the reader before addressing the four criteria. Soundcool is like a ¿Lego¿ for sound; Soundcool is composed of a series of software modules that run on a central computer, or host computer. Each module is sort of a musical instrument; it could be a synthesizer, a sampler, a sound effect processor, etc. these modules can be interconnected in different ways allowing the users, i.e. the students, to create their own arrangements, as we call the module creations and interconnections. Then, each module can be controlled either with the mouse or, what is more interesting, with a mobile device through WiFi. This way, every student can control one or several modules of the whole arrangement from their mobile device contributing to a collaborative and participative experience.This work is supported by Daniel & Nina Carasso Foundation, project 16- AC-2016 and Cátedra Telefónica-UPV 2016-17Robles-Mateo, E.; Serquera, J.; Lloret Romero, MN.; Sastre, J.

Thermodynamic analysis of CO2 removal process by adsorption on NaX

The continuous increase of carbon dioxide concentration in the atmosphere is the main contributor to climate change. Thus, it is imperative to develop strategies that help to control manmade emissions of this gas. Carbon dioxide capture is an intensive research area that aims to decrease the energy requirements for the separation and storage of CO2. Even though absorption using an aqueous solvent is a well-established and is the most widely implemented capture technology, it requires high energy for the regeneration of the solvent due to the need to increase the temperature of the aqueous solvent, decreasing the overall efficiency of the process. Adsorption using porous solids has been presented as an alternative process to capture CO2 while decreasing the energy requirements. In the present work, a thermodynamic analysis of the CO2 removal process by adsorption using literature reported data is performed, in order to devise a framework to evaluate and compare two adsorbents under realistic process conditions. Zeolites NaX and Beta were used as case studies to evaluate the proposed model. The results show that, although bed composition profiles have similar trends for both adsorbents, there is a significant difference in the regeneration temperature of these adsorbents, since for zeolite NaX the regeneration temperature is reached around 360K when CO2 is almost pure, whereas for Beta this value is reached around 390K. Thus, NaX has a lower energy requirement than Beta for stablished process conditions. The energy penalty is 91.08 MW per molCO2 recovered for NaX and 104.28 MW per molCO2 recovered for Beta, which is consistent with the calculation of the specific thermal energy and the working capacity

Transformaciones de la escritura : una experiencia desde el enfoque sociocultural

RESUMEN: Nuestro trabajo de profundización se ocupa de la deconstrucción y transformación de las prácticas pedagógicas relacionadas con la enseñanza de la escritura asumida como proceso desde una perspectiva sociocultural. Para ello, diseñamos, implementamos y evaluamos tres secuencias didácticas a partir de tópicos locales: lugares emblemáticos, personajes representativos y sitios comerciales. Lo anterior fue orientado desde el paradigma cualitativo a partir del método de Investigación Acción, recopilando las voces de los participantes y los detalles del proceso a través de instrumentos como el diario de campo y la entrevista semiestructurada, que seguido constituyen las categorías de análisis en el proceso de triangulación. De esta forma, concluimos que es posible transformar nuestras prácticas de aula partiendo de nuevas formas de configurar la enseñanza de la escritura, una escritura que se conecte con la vida y la realidad de nuestros contextos, yendo más allá de los muros de la escuela y al mismo tiempo de nuestras viejas concepciones.ABSTRACT: Our work of deepening takes care of the deconstruction and transformation of the pedagogical practices related to the teaching of the writing assumed like process from a sociocultural perspective. To this end, we design, implement and evaluate three didactic sequences from local topics: emblematic places, representative characters and commercial sites. The above was oriented from the qualitative paradigm from the action research method, Gathering the voices of the participants and the details of the process through instruments such as the field diary and the semi-structured interview, configuring these in categories of analysis for triangulation In this way we come to the conclusion that it is possible to transform our classroom practices starting from new ways of setting up the teaching of scripture, a scripture that connects with the life and reality of our contexts, going beyond the walls of the school and at the same time of our old conceptions

Complex Unfolding Kinetics of Single-Domain Proteins in the Presence of Force

Single-molecule force spectroscopy is providing unique, and sometimes unexpected, insights into the free-energy landscapes of proteins. Despite the complexity of the free-energy landscapes revealed by mechanical probes, forced unfolding experiments are often analyzed using one-dimensional models that predict a logarithmic dependence of the unfolding force on the pulling velocity. We previously found that the unfolding force of the protein filamin at low pulling speed did not decrease logarithmically with the pulling speed. Here we present results from a large number of unfolding simulations of a coarse-grain model of the protein filamin under a broad range of constant forces. These show that a two-path model is physically plausible and produces a deviation from the behavior predicted by one-dimensional models analogous to that observed experimentally. We also show that the analysis of the distributions of unfolding forces (p[F]) contains crucial and exploitable information, and that a proper description of the unfolding of single-domain proteins needs to account for the intrinsic multidimensionality of the underlying free-energy landscape, especially when the applied perturbation is small

El derecho a la propiedad y el fenómeno de la ocupación: las Fuerzas y Cuerpos de Seguridad como actores clave

Treball Final de Grau en Criminologia i Seguretat. Codi: CS1044. Curs acadèmic: 2022/2023El derecho a la propiedad es un derecho reconocido en el artículo 33 de la Constitución Española, por lo que este Trabajo Final de Grado tiene como objetivo realizar un acercamiento a este derecho y poder relacionarlo con el derecho fundamental a la inviolabilidad del domicilio, todo ello con el objetivo último de conocer mejor el conflicto que surge entre ambos en el caso de las ocupaciones de inmuebles y analizar el papel que desempañan las Fuerzas y Cuerpos de Seguridad para dar respuesta a estas situaciones. Se examinan los delitos (allanamiento de morada y usurpación) y la infracción administrativa relacionada con la ocupación, así como la evolución estadística de la ocupación de inmuebles entre los años 2017 y 2022. Asimismo, se analizan las opiniones de los ciudadanos españoles de cómo debería actuar el Estado, así como la sensación subjetiva de la sociedad por sufrir una intrusión. Un elemento fundamental de este Trabajo Final de Grado es analizar la Instrucción 6/2020 de la Secretaría de Estado de Seguridad para determinar la actuación de las Fuerzas y Cuerpos de Seguridad, que son uno de los actores clave ante esta situación y tienen un papel muy importante en la prevención y reducción en la inseguridad de los ciudadanos.The right to property is a right recognized in article 33 of the Spanish Constitution, so this Final Work of Degree aims to make an approach to this right and to relate it to the fundamental right to the inviolability of the home, all this with the ultimate objective of knowing better the conflict that arises between both in the case of real estate occupations and analyze the role that the Security Forces and Bodies play to respond to these situations. It examines the crimes (burglary and usurpation) and the administrative infraction related to the occupation, as well as the statistical evolution of the occupation of real estate between 2017 and 2022. It also analyzes the opinions of Spanish citizens on how the State should act, as well as the subjective feeling of society for suffering an intrusion. A fundamental element of this Final Work of Degree is to analyze Instruction 6/2020 of the Secretary of State for Security to determine the performance of the Security Forces and Bodies, who are one of the key players in this situation and have a very important role in preventing and reducing the insecurity of citizens
