Dahan, Kevin. „Domaines formels et représentations dans la composition et l'analyse des musiques électroacoustiques : systèmes dynamiques dans la création musicale assistée par ordinateur“. Paris 8, 2005. http://www.theses.fr/2005PA083580.
Der volle Inhalt der QuelleSome theories and technical approaches used to characterize the computer-assisted composition process are presented. Theories and techniques unusually used in the field of computer music are applied to the numerous problems raised by a musicology of electroacoustic music and its genetic ontology. A critical deconstruction of methods and tools used to characterize musical creation is developed and a novel conceptual tool is exposed, and formalized. The notion of object, which permits a multiscalar reading of the creative process, is described and an adaptation of the traditional electroacoustic toolkit is made neccesary by the object considered as a multiscalar seme. A prototype of a compositional system gives a first answer in order to present complexity

Der volle Inhalt der QuelleCORDIS-ANIMA is a general system for designing and simulating physical models made of modules that represent simple material elements and physical interactions. This system is implemented in a software environment for musical creation, GENESIS, which addresses sound synthesis as well as musical composition. In this thesis, we propose a general organization of musical CORDIS-ANIMA models, by identifying the elementary functions that are realized within a model, the types of physical components associated to these functions, and the main modelling techniques, which enable to obtain musically relevant physical behaviours. This work forms the conceptual basis of an Instrumentarium for musical creation using CORDIS-ANIMA, i. E. A structured and consistent view of modelling with the system, which aims at helping users to learn and master it, particulary in the GENESIS environment
Lopez, Charles Carlos. „La convergence musicale entre les médias visuels et musicaux dans la création de la musique visuelle“. Thesis, Paris 8, 2015. http://www.theses.fr/2015PA080142/document.
Der volle Inhalt der QuelleHow can the musical convergence between sound and image, between audio en video, be achieved when working with digital technology? What is "musicable" in the visual domain? I suggest that the musical convergence is achieved through the use of technological devices that allow to 1) establish a certain degree of interaction between the musical and visual media, and 2) manipulate visual materials through an ensemble of compositional operations that are coherent with a given musical paradigm. On this basis, we suggest that what is "musicable" in the visual domain is the ensemble of visual variables that can be manipulated during the compositional process, to the extent in which they make musical sense. The research begins by identifying the historical context that set the conditions for the musical convergence between visual and musical media. We then present a multiple case study that is integrated by 12 works which belong different stages of the history of visual music. The study reveals the use of 41 methods to craft the musical convergence between visual and musical media. The final chapter presents an artistic demonstration of the use of the methods and concepts that emerged from our multiple case study. The conclusions present a synthesis of the results, a discussion of the interaction between theoretical and practical approaches, and my personal reflections on the pathways for future research in the field
Sousa, Dias António de. „L'objet sonore : situation, évaluation et potentialités : un paradigme pour la création d'outils de composition musicale“. Paris 8, 2005. http://www.theses.fr/2005PA082612.
Der volle Inhalt der QuelleWe propose a study on the composition potentialities resulting from the conjunction of the object sound concept and the progressive transfer of musical technologies to the digital media. Beginning with the sound object of Schaeffer, through the writings of other authors (Bayle, Smalley, Wishart), we arrive at the concept of digital sound object of Vaggione, which articulates this conjunction. Two consequences result: the statement of the enlargement of musical writing and a compositional attitude based upon the idea of a work as the result of an interface to a musical database (adapted from Manovich). Finally we describe the software and the works which guided us to two concrete results: a software for external patches management (KITTy) and the music for the “found footage” documentary Nature Morte which would not have been possible without the reflection and consequences presented here

Der volle Inhalt der Quelle. In this thesis we study the possibility to introduce the concept of style in declarative modelling in order to aid architectural design during the conceptual phase. In order to study such a hypothesis we have develop a methodology of architectural conceptual design utilising style. The method is based in the frame of declarative modelling, and evolutionary algorithms. In particular, we develop a framework for the modelling of architectural knowledge. We define a model of style based on the declarative conceptual cycle. Moreover we develop a new engine for the generation of solutions. This engine is based on multiobjective genetic algorithms. The result is a system prototype for Evolutionary Declarative Design-MultiCAD for the aid of conceptual architectural design. The resulted method could successfully quantify aesthetic qualitative criteria of a building. Our system points towards a computer aided aesthetic design tool

Der volle Inhalt der QuelleWithin information societies the World Wide Web is a kind of technology that takes advantage of an ever-increasing important role played by digital and network technologies. Respectively, the space of the Web may be perceived as a digital machine to communicate, but also as a signifying space where several codes of signification exist according to logics and pragmatics of usage. From this scenario, the main objective of our research is to analyze in which manner the Web may serve educational practices taking into account its multi-functionality as well as its possibilities to represent different knowledge structures. In first place, we examine the Web as a technical object in order to go beyond instrumental conceptions; rather we are interested to define a communicational perspective. Then, we study the evolution lines of technical objects with the intention to propose an applicative ground for educational structures. At last, we introduce a prototype system developed to support our theoretical framework and we discuss some conclusions from first user experiences

Der volle Inhalt der QuelleThe emergence of artificial intelligence programs capable of generating artistic works, musical works and literary works raises many stakes, especially in copyright since it becomes harder to notice the difference between creations made by a human and creations made by artificial intelligence. If these creations can nowadays be mistaken, then it is relevant to question ourselves about the legal system that is applicable to them. Not long ago, questions about copyright on work created by computer programs didn’t create debates since programs were only considered as a tool for the author’s use. However, the recent progress of artificial intelligence programs shows that their implication in the process of creation goes beyond simple assistance. Therefore, it becomes necessary to question ourselves on the identity of the work’s author, the copyright ownership and the opportunity of recognizing a juridical personality to the artificial intelligence.

Der volle Inhalt der QuelleThis action research was meant to design digitised learning resources as an integrated complement to a specific teaching context. In the light of current theoretical knowledge on second language acquisition and the use of information and communication technology, a learning system was implemented in which the resources had the role of developing explicit knowledge. Once in operation the resources were assessed through detailed measurements. They fulfil their function to the learners’ satisfaction although parts of their contents and aspects of their layout need amending. Using such resources entails that teachers should assume new functions requiring new skills. This action research, prompted by a sense of deontological responsibility, led to the achievement of greater theoretical expertise and the adoption of more reliable teaching practices. Thanks to rigorous methodology the hypotheses have been validated and the practices can be transferred to other contexts

Der volle Inhalt der QuelleThis PhD research project aims at developing a new Personalized Garment Design Support System (PGDSS) for People with Atypical Morphology (PWAM). This system enables to quickly develop garments adapted to their special Functional, Expressive and Aesthetic (FEA) needs and atypical morphologies. In order to realize the proposed PGDSS, two subsystems are developed: the Personalized Fashion Recommendation System (PFRS) and Virtual 3D-to-2D Garment Prototyping Platform (VGPP). The PFRS is developed for selecting the most relevant personalized garment design solutions in terms of color, fabric and style, while the VGPP enables designers to quickly create virtual garments according to their design criteria (product profiles) and visualize them in order to adjust design parameters. The proposed PGDSS can be fully used online. It can be further connected to a garment e-shopping platform or an offline automatic garment manufacturing system.The design factors for personalized garments have been identified and analyzed in my PhD research. The new products generated by the proposed system will meet the specific demands and functions imposed by people with atypical morphology in terms of ergonomics, biophysics, psychology, aesthetics, comfort and convenience. The proposed system is able to offer more personalized designs at low-cost level for highly customized garment market
Leonard, James. „La Plateforme MSCI : vers un outil de création d'instruments virtuels à retour d'effort. Application à la création musicale“. Thesis, Université Grenoble Alpes (ComUE), 2015. http://www.theses.fr/2015GREAS036.
Der volle Inhalt der QuelleThe notion of instrumentality can be defined as the corporal relationship between a human and a physical object, called an instrument. This intimate situation simultaneously addresses the various human action and perception sensory canals, and constitutes a vector for enactive knowledge. In particular, this instrumental relationship plays a key role in the expressiveness of musical instruments.In the digital context, a vast area of research concerns sensory interactions with virtual entities, by means of sensors and actuators, including gestural interaction with force feedback systems. On the one hand the Virtual Reality domain, historically focused on visual aspects, generally focus gestural interaction on spatial features, often losing the focus of dynamic features. On the other hand, Digital Musical Instruments are essentially centered on interactive control of digital sound synthesis processes, grounded in information technologies and signal processing. These two approaches synthesize sensory phenomena destined to different perceptive channels following a multimodal approach, the virtual object being decomposed into subsections, linked together by control relations.It is however possible to conceive systems that allow for instrumental interaction with a virtual simulated object, maintaining total and bidirectional energetic coherence, from gesture to sound and reciprocally. In this case, it is necessary to bring together (a) a physical modeling formalism that allows creating intrinsically multisensory virtual objects that possess visual, acoustical and haptic properties, (b) force feedback systems with high dynamic performances and (c) specialized computation architectures that allow for a reactive, high rate synchronous simulation loop.The work of this thesis consists in the extension and convergence of concepts and techniques hereby mentioned here-above, in order to create a platform for instrumental musical creation, named MSCI (Modeleur Simulateur pour la Création Instrumentale), proposing a multi-rate architecture for the simulation of virtual musical instruments on a new dedicated simulation architecture. A modeling environment allows complete design of the virtual instrument based on mechanical and physical principles, and to configure the haptic coupling between this instrument and the user during the force-feedback simulation.Notably, it addresses the separation of the instrumental chain into zones which present mostly non-vibrating phenomena within a dynamic range close to the human sensory-motor gesture, and zones which vibrate at acoustical rates, producing sound. These two sections of the instrument may be simulated at different rates, adapted to the physical phenomena that they give birth to. In the scope of a physical modeling formalism that guarantees the energetic coherence of simulated objects, this multi-rate separation is a new topic that requires careful handling, in terms both or respect of the physical coupling and of numerical stability.To our knowledge, this is the first environment for musical creation by means of physical modeling that allows for instrumental manipulation of multisensory virtual instruments, respecting an energetic coherence between the human and the instrument, and therefore allowing embracing the creative potential of digital sound synthesis while disposing of the intimacy and expressiveness of instrumental gestures. Beyond the musical scope, this work provides the basis and the technological tools for the emergence of a true multisensory form of art, jointly addressing vision, hearing and gesture

Der volle Inhalt der QuelleAI systems can produce outputs that may purportedly be subject to copyright. To investigate this possibility, one should avoid the use of a rough model of copyright law, and an approximative description of the facts. Artificial production should be envisaged realistically, being serial and non-convergent. Most of the time, there is not one sole artificial output obtained by the so-called “AI user”. On the contrary, there are mostly supernumerary outputs due to the use of an indirect and highly iterative kind of software engineering. Then we understand the reason why this cannot be subject to copyright protection. Free choices are only creative towards works of authorship, not their indirect computed implications. This is also a confirmation of the consistency of copyright law: it protects what the author has conceived and realized, what is not excessively impeded by technical constraints, what is objectively and precisely identifiable… As a consequence, authorial determination, creative convergence and social intelligibility appear as unavoidable preconditions of copyright law
Gavazza, Giuseppe. „La synthèse par modèle physique comme outil de formalisation musicale“. Thesis, Université Grenoble Alpes (ComUE), 2018. http://www.theses.fr/2018GREAS041.
Der volle Inhalt der QuellePhysical model synthesis offers an approach to composition alternative to the more usual signal processing. Considering the musical phenomenon as a "unicum" emerging from the interaction between the musicians and their instruments the physical model synthesis realizes and gives phenomenological and sensitive corporeality to the creative actions. By conceiving not as separate entities sound material and musical structure directs the potentialities of the computer and creates an original and fruitful dialectic between the formal (structural) and perceptual (cognitive).The sphere of action for my PhD concerns the development, formalisation and categorisation of structural models – created by physical modelling – useful for musical composition in the perspective to highlight the musical formalisation function associated with the CORDIS-ANIMA physical model simulation paradigm.The starting point for this work is 20 years of personal use as a composer, of the GENESIS physical model musical creation software developed by the ACROE-ICA laboratory.This experience has led me, through works both scientific (modelling) and artistic (music composition), to consider this environment not as a synthesis tool, but as a complex instrument, which allows to create a complete musical composition covering all three usual categories of acoustics and music: micro-formal (the tone, harmony, orchestration), mezzo-formal (the rhythm, melody, and the basic sequences/harmonic structures) and macro-formal (the higher level harmonic structure, the formal outline of the entire composition).My goal is not to propose the framework of a new music or a new aesthetic, but develop "well-tempered" instruments for a new practice of music creativity that explores and accomplishes better the potentialities of computer and digital technology. This also leads in the direction of broadening the dialectic instrumentality - writing music to a "supra instrumentality" [Cadoz6] and to post-scriptic outlook on musical creation [Cadoz7]

Der volle Inhalt der QuelleThis thesis concerns the conception and development of a computer-assisted navigation sys- tem for endovascular surgery. The clinical application is the treatment of abdominal aortic aneu- rysm. The objective is real-time tracking, in pre-operative CT images, of the position of an aortic endoprosthesis inserted in the femoral artery. This research deals with the deưnition of relevant data from imaging and localization systems, as well as their processing and registra- tion for a minimally invasive navigation. The arterial tree is located in the Operating Room reference system through freehand ultrasound. An original 2D/3D registration method, based on prior knowledge, provides the transformation to register ultrasound images and pre-operative CT volume. The magnetic sensors' integration within the vascular guide allows a non invasive localization of the endoprosthesis inside the patient's aorta. Fusion of images and localization data permits real-time calculation of anatomical CT slices that correspond to the position of endovascular elements. The navigation system oers thus a non-radiative 3D visualization of the endoprosthesis. This thesis comprises several domains of computer assisted surgery : CT and ultrasound registration, calibration of magnetic and optical localization systems, calibration of a freehand ultrasound probe, and the conception of tools for a minimally invasive intervention. Preclinical validation on an anatomical piece has demonstrated an accuracy compatible with the objectives of endovascular surgery. Clinical tests on patients are underway

Der volle Inhalt der QuelleThis thesis discuss of the use of immersive environments of Virtual Reality (VR) for Computer Aided Design (CAD). We study how these new interfaces between man and information systems can improve the different tasks of geometric shape design that are actually done on workstation with screen. These workstations essentially use keyboard, mouse and graphical interface. However this kind of interaction does not take advantage of VR possibilities in term of direct 3d interaction. In addition, CAD objects does not allow ways to modify there shape with a direct and 3d interaction. We present an approach of reactive objects that allows changing the value of operations parameters in the construction history graph of the solid, from direct interaction of the user on the elements (vertex, edge, face) of the B-Rep of the solid. To this purpose, we use an inference system that decides what parameters to modify knowing the selected element, and how to map the manipulations of the user to numerical changes of the parameters. These inferences are based on sets of rules dealing with construction information attached to the elements of B-Rep. This model of reactive objects has been implemented in a software prototype allowing creation and modification of CAD objects in an intuitive way. The interface proposed is a multimodal and immersive environment. We also propose in this thesis a method for collision detection dedicated to immersive interaction and a graphic rendering system on PC cluster adapted to deformable objects

Der volle Inhalt der QuelleThe Electron Beam Melting (EBM) process allows to build metallic parts from powder. Thanks to the geometric and mechanical quality of the parts produced, the EBM process can be used to manufacture functional parts and not only prototypes. This process, with other additive metallic processes, make it possible to consider a transition from 3D printing to metallic additive manufacturing.The use of additive manufacturing in an industrial environment requires compliance with quality, cost and time criteria for the parts produced. The production of manufactured parts involves a series of numerical stages which is called the numerical chain. The numerical chain has a significant impact on the three criteria mentioned above. Thus, this thesis provides an answer to the following question:How Computer Aided Manufacturing can improve the quality, cost and time of the EBM manufacturing process?This problem is addressed through the following underlying question:What are the required characteristics for a Computer Aided Manufacturing system adapted to the EBM process?In order to answer this question, the current numerical chain is analyzed. Three main limitations are found:- the use of STL files format- the process cannot be optimized at different scales- the process cannot be simulatedTo solve these issues, a CAM environment is proposed. It allows the centralization of all numerical operations in a single environment. All supported formats can be used within this environment, such as native CAD file formats or STEP format. Software developments are done to prove the feasibility of such an environment.The CAM environment implementation reveals the crucial role of simulation in this system. It is therefore necessary to answer this second question:How to obtain an EBM process simulation allowing the development of parameters, virtually?Although EBM simulation is a recurrent subject in scientific literature, existing studies are based on the finite elements method but the calculation time needed is too important to be used in an CAM environment. Thus, an alternative type of simulation is created in this thesis: a simulation based on abacus. It is composed of a finite elements model, that allows heat maps generation for standards cases of heating and cooling. These heat maps are then transformed in abacus. The simulation algorithm based on abacus search the nearest abacus from the simulated situation in order to estimate the temperatures at the next time step.This simulation method was used to reduce the calculation time while keeping a sufficient precision to optimize process parameters.With the simulation based on abacus, a tool for the optimization of melting strategies is developed. This tool allows quality improvement for the produced parts through the calculation of melting strategies according to thermic criteria.To summarize, the main contributions of this work are:- the definition of requirements specifications of a powerful numerical chain for the EBM process- the development of a CAM environment adapted to the EBM process- the proposal of a fast simulation for the EBM process, based on abacus- the development of a tool for the optimization of melting strategies

St~d!es the preoperative planning step of tumor thermal ablation. The aim is to develop mtmtIve and automated tools to assist the selection of an optimal operative strategy, specifie to each intervention. We propose an original approach inspired by declarative modelling in CAD. This approach considers basic planning rules defined by experts as data, possibly modifiable and adaptative regarding their use. In this goal, we propose a constraints definition language in order to express them in a simple way. We also developped a generic solver that adapts itself to defined contraints. The sol ver detects the solutions set associated to each case and proposes optimal intervention strategies. We have also developped sorne interface tools in order to provide to the surgeon an intuitive planning software, displaying precious information for the choice of an operative strategy
Dias, Fernandes João Eduardo. „L’improvisation musicale électroacoustique : enjeux et problématiques du développement des technologies numériques“. Thesis, Paris 8, 2019. http://www.theses.fr/2019PA080026.
Der volle Inhalt der QuelleThis research/creation thesis is centred on the exploration of musicians’ needs for the practice of electroacoustic music improvisation. This investigation was conducted through participant observation with different musical ensembles. It also presents the strategies adopted for the development of digital tools in the case of a created musical instrument. How does the practice of free improvisation in electroacoustic music work and what knowledge is needed to achieve free improvisation? To answer these questions, several paths were taken: for example considering the context of the performance and by challenging the musical and extramusical aspects surrounding the improvised action. Furthermore, this research deployed a study of the characteristics of a digital instrument that endeavours to possess the same flexibility as acoustic instruments. The “creation” component of this thesis is through the development of a digital instrument (RJ). This instrument is implemented with a sound samples recommendation system. It was used in situation of improvisation with several ensembles, which form part of the corpus of data of this thesis. Lastly, this thesis seeks to characterize musical improvisation through the multiple interactions that occur during an improvised performance. The research therefore provides a practical and theoretical framework for the use and exploration of contemporary digital tools for musicians, which practice collective free improvisation
Bazin, Théis. „Designing novel time-frequency scales for interactive music creation with hierarchical statistical modeling“. Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS242.
Der volle Inhalt der QuelleModern musical creation unfolds on many different time scales: from the vibration of a string or the resonance of an electronic instrument at the millisecond scale, through the few seconds typical of an instrument's note, to the tens of minutes of operas or DJ sets. The interleaving of these multiple scales has led to the development of numerous technical and theoretical tools to ease the manipulation of time. These abstractions, such as scales, rhythmic notations, or even usual models of audio synthesis, largely infuse current tools -- software and hardware -- for musical creation. However, these abstractions, which emerged for the most part during the 20th century in the West on the basis of classical musical theories of written music, are not devoid of cultural a priori. They reflect various principles aimed at abstracting away certain aspects of the music (for example, micro-deviations with respect to a metronomic time or micro-deviations of frequency with respect to an idealized pitch), whose high degree of physical variability makes them typically inconvenient for musical writing. These compromises, typically relevant when the written music is intended to be performed by musicians, able to reintroduce variations and physical and musical richness, are however limiting in the context of computer-assisted music creation, with computers coldly rendering these coarse representations abstractions, and they tend to restrict the diversity of the music that can be produced with these tools. Through a review of several typical interfaces for music creation, I show that an essential factor is the scale of the human-machine interactions proposed by these abstractions. At their most flexible level, such as audio representations or piano-roll representations with unquantized time, they prove difficult to manipulate, as they require a high degree of precision, particularly unsuitable for modern mobile and touch terminals. On the other hand, in most commonly used abstractions with discretized time, such as scores or sequencers, they prove to be too constraining for the creation of culturally diverse music that does not follow the proposed time and pitch grids. In this thesis, I argue that artificial intelligence, through its ability to build high-level representations of given complex objects, allows the construction of new scales of music creation, designed for interaction, and thus enables radically new approaches to music creation. I present and illustrate this idea through the design and implementation of three web-based prototypes of music creation assisted by artificial intelligence, one of which is based on a new neural model for the inpainting of musical instrument sounds also designed in the framework of this thesis. These high-level representations -- for sheet music, piano-rolls, and spectrograms -- are deployed at a time-frequency scale coarser than the original data, but better suited to interaction. By allowing localized transformations on these representations but also capturing, through statistical modeling, aesthetic specificities and fine micro-variations of the original musical training data, these tools allow to easily and controllably obtain musically rich results. Through the evaluation of these three prototypes in real conditions by several artists, I show that these new scales of interactive creation are useful for both experts and novices. Thanks to the assistance of AI on technical aspects that normally require precision and expertise, they are also suitable for use on touch screens and mobile devices

Der volle Inhalt der QuelleThe object of our research in linguistics was basically the identification process of the referent of french personal pronoun il. The process calls for a formalisation procedure in the perspective of computer-aided translation (CAT) systems. Consequently, this research is not a study on anaphora, even if this concept remains central to the investigation. The study refers essentially to the first stage of the CAT procedures : analysis. We examined il successively as an impersonal and personal pronoun, and tried to identify or rather "calculate" the right antecedent. The corpora used for experimentation were of two types : literary (Les mots by Jean-Paul Sartre) and legal / technical (Esprit Report published by the EEC Commission). The research is therefore primarily theoritical. The point was to investigate the possibility of elborating a grammar of logic or modular type, and a dictionnary or data base that could be used at a later stage by an expert system designed to identify automatically the right antecedent. The process had to leave no room to intuitive procedures that cannot be supported by CAT systems in current state-of-the-art conditions. As a consequence, operations can be validated only if formalisation is possible. However, some amount of knowledge can be integrated into the process. In short, the study can be considered as a contribution to some of the issues involved in the man-machine dialogue issue. The application of the model provided following results : il is properly identified as an impersonal pronoun in 96% cases and the antecedent of the personal pronoun is recognised in 95. 52 occurences. Various methods including quantitative analysis, knowledge representation in pragmatics, application of unification-based grammars, Discourse Representation Theory (DRT), lexical functions, pointed at interesting solutions to solve the remaining 5% ambiguous cases. The obvious follow-up to this study would consist in the writing of a program and an implementation of the data collected to check on the valididity of the results mentioned above

Der volle Inhalt der QuelleThis work is related with the automatic inspection of manufactured parts by using the CAD model of the part and the cloud of 3D points obtained by the digitization of the part with a range sensor. Initially we determine and model the parameters which influence the accuracy of the range sensor in the digitalization of a part. This model is used to produce automatically a sensing plan in order to acquire completely and precisely the geometry of a surface or of a complete part. A sensing plan consists of a set of viewpoints which defined the exact position and orientation of the camera relative to the part and other digitizatioin parameters. The goal of the sensing plan is to improve the accuracy of the depth measurement in order to be able to use the cloud of 3D points in inspection tasks. The requirements of the system are the exact position and orientation of the part and its CAD model in IGES format. There is no limitation in the geometry of the part to be digitized, hence simple / complex parts can be scanned. After registration between the 3D data and the CAD model, the cloud is segmented. The segmentation is fulfiled by computing the minimal distance from the 3D point to the surfaces (of the CAD model) and comparing some local geometric properties of the 3D point with the closest one on the surfaces. Segementation results are used to check dimensional and geometric tolerances of the part. By using the model of the noise we have introduced a dispersion value on each 3D point acquired by the range sensor. This value of dispersion is presented as a weight factor in the results of the dispersion

C'est pourquoi nous proposons aussi dans cette thèse un nouveau modèle d'architecture logicielle plus flexible et dynamique, qui, une fois réalisé dans la boîte à outils MAGGLITE, nous a permis de faciliter et d'encourager le prototypage et la réalisation d'interactions avancées.
