description: We analyze the tail behavior of solutions to sample average approximations (SAAs) of stochastic programs posed in Hilbert spaces. We require that the integrand be strongly convex with the same convexity parameter for each realization. Combined with a standard condition from the literature on stochastic programming, we establish non-asymptotic exponential tail bounds for the distance between the SAA solutions and the stochastic program's solution, without assuming compactness of the feasible set. Our assumptions are verified on a class of infinite-dimensional optimization problems governed by affine-linear partial differential equations with random inputs. We present numerical results illustrating our theoretical findings.

description: Le statut de la musique à l’école a constitué la préoccupation principale de ce travail. Il faut souligner que le nombre de périodes d’enseignement réservé à la musique est quelque peu insignifiant par rapport à certaines autres disciplines. L’évaluation des systèmes éducatifs est particulièrement orientée sur le développement d’une pensée logico-mathématique. Notre questionnement concerne l’impact de la musique sur le développement des facultés cognitives, affectives et psychomotrices. De nos jours, de nombreux chercheurs mettent en évidence les interactions entre la musique et les sciences cognitives. Dès lors, comment expliquer le peu d’intérêt manifesté pour la musique en tant que discipline formative par les autorités déontiques ? La présente recherche met en évidence les relations entre la musique et les différentes composantes de l’intelligence, y compris la mémoire. Par ailleurs, cette étude démontre aussi le développement des fonctions cognitives favorisé par une pratique musicale qui optimise le fonctionnement global de l’individu. Dans la littérature du genre, les notions de mémoire et d’intelligence ne sont pas toujours employées à bon escient. Ce travail éclaircit la définition de ces deux concepts afin d’éviter toute forme de confusion. De surcroît, la mémoire constitue un élément essentiel dans le développement de l’intelligence musicale. D’ailleurs, les recherches de Baddeley entre autres ont orienté cette étude afin de définir les concepts-clés de la notion de mémoire et spécifiquement l’encodage musical ainsi que les mémoires mélodiques et harmoniques. Le développement des facultés cognitives généré par la musique est consolidé par les disciplines à caractère littéraire et scientifique. L’optimisation de cette consolidation peut s’opérer par un statut horaire équitable et harmonieux entre ces disciplines.

description: Quantitative stochastic homogenization of linear elliptic operators is by now well-understood. In this contribution we move forward to the nonlinear setting of monotone operators with $p$-growth. This work is dedicated to a quantitative two-scale expansion result. By treating the range of exponents $2\le p <\infty$ in dimensions $d\le 3$, we are able to consider genuinely nonlinear elliptic equations and systems such as $-\nabla \cdot A(x)(1+|\nabla u|^{p-2})\nabla u=f$ (with $A$ random, non-necessarily symmetric) for the first time. When going from $p=2$ to $p>2$, the main difficulty is to analyze the associated linearized operator, whose coefficients are degenerate, unbounded, and depend on the random input $A$ via the solution of a nonlinear equation. One of our main achievements is the control of this intricate nonlinear dependence, leading to annealed Meyers' estimates for the linearized operator, which are key to the optimal quantitative two-scale expansion result we derive (this is also new in the periodic setting).

description: Notre travail de mémoire HEPL consiste en la création d’un QCM dont l’objectif est non seulement de tester les connaissances des élèves sur les fonctions quadratiques mais aussi, au travers de l’analyse de leurs erreurs, d’identifier les compétences qui n’ont pas été acquises. Nous présentons tout d’abord une possible classification des questions mathématiques, afin d’en déterminer la complexité et de pouvoir les comparer. Cette classification nous permet d’associer des compétences à chaque niveau. Nous posons ensuite les bases de la réalisation d’un QCM et présentons les choix effectués pour l’élaboration de nos questions. Cette partie est suivie par une analyse a priori des questions ainsi créées et par la détermination de la classification associée à chacune d’entre elles. Nous proposons ensuite une vue d’ensemble des questions en les classant dans une grille selon trois axes : Difficulté, Cadre\ Registre et Taxonomie, vérifiant ainsi la couverture du sujet. Nous enchaînons avec la présentation d’hypothèses sur les compétences manquantes en fonction de la position des questions dans cette grille. Nous passons alors à la présentation et l’analyse des résultats du QCM testé auprès d’une quarantaine d’élèves et terminons avec un bilan de ce travail. Il ressort de ce travail que l’élaboration d’un QCM est très coûteuse en temps et difficilement adaptable à des problèmes de mathématique, mais toutefois possible. Nous relevons que l’évaluation par QCM uniquement peut être dévastateur pour des élèves moyens, c’est-à-dire des élèves qui savent que faire, mais commettent quantité de petites des fautes de calcul. Il est toutefois très instructif de se prêter de temps à autre à cet exercice, car il oblige à réfléchir différemment, à chercher des nouvelles stratégies pour tester les objectifs souhaités.

description: Entanglement entropy in conformal field theories is known to satisfy a first law. For spherical entangling surfaces, this has been shown to follow via the AdS/CFT correspondence and the holographic prescription for entanglement entropy from the bulk first law for Killing horizons. The bulk first law can be extended to include variations in the cosmological constant $Λ$, which we established in earlier work. Here we show that this implies an extension of the boundary first law to include varying the number of degrees of freedom of the boundary CFT. The thermodynamic potential conjugate to $Λ$ in the bulk is called the thermodynamic volume and has a simple geometric formula. In the boundary first law it plays the role of a chemical potential. For the bulk minimal surface $Σ$ corresponding to a boundary sphere, the thermodynamic volume is found to be proportional to the area of $Σ$, in agreement with the variation of the known result for entanglement entropy of spheres. The dependence of the CFT chemical potential on the entanglement entropy and number of degrees of freedom is similar to how the thermodynamic chemical potential of an ideal gas depends on entropy and particle number.

description: A través de la historia el diseño gráfico mediante sus manifestaciones y técnicas de reproducción este refleja una línea del tiempo donde se aprecian las tendencias y técnicas de reproducción que han estado al alcance de la humanidad. La presente tesis doctoral documenta a través de un caso de estudio de comunicación visual el valor del diseño gráfico como herramienta para contribuir en la creación de identidad regional, esto mediante el objeto de estudio “Cervecería de Mexicali S.A.”, empresa establecida en el año de 1923 en la ciudad de Mexicali, Baja California, al noroeste de la república mexicana. Su apertura llegó durante una época de transformación cultural en la región la cual es consecuencia de diversos factores políticos y económicos, entre ellos, se destaca la Ley Volstead o Ley seca. Esta norma que abarcó el periodo de 1919 a 1933 prohibía el consumo y fabricación de bebidas alcohólicas en los Estados Unidos, lo que permitió el inicio actividades de empresas cerveceras la ciudad de Mexicali reflejándose rápidamente en el incremento del turísmo y el exponencial desarrollo urbano, factores que respondieron a una recursividad entre la economía, la sociedad y la política. Es en este momento del pasado que, ante la alta demanda de productos y servicios relacionados en la industria del entretenimiento y el alcohol que se dieron los primeros registros de productos y técnicas publicitarias en la región, que en el caso de la Cerveza Mexicali, gradualmente fueron creando un sentido de pertenencia, pues la marca al llevar el nombre de la ciudad representó un producto a partir de símbolos con los cuales la sociedad se podía identificar, la cual al ser conformada día a día por migrantes y sus familias vieron en la imagen del producto un elemento al cual los abrazó a todos bajo una nueva identidad y sentido de pertenencia.

description: We give a detailed account of equilibrium and non-equilibrium fluctuational electrodynamics of hyperbolic metamaterials. We show the unifying aspects of two different approaches; one utilizes the second kind of fluctuation dissipation theorem and the other makes use of the scattering method. We analyze the near-field of hyperbolic media at finite temperatures and show that the lack of spatial coherence can be attributed to the multi-modal nature of super-Planckian thermal emission. We also adopt the analysis to phonon-polaritonic super-lattice metamaterials and describe the regimes suitable for experimental verification of our predicted effects. The results reveal that far-field thermal emission spectra are dominated by epsilon-near-zero and epsilon-near-pole responses as expected from Kirchoff's laws. Our work should aid both theorists and experimentalists to study complex media and engineer equilibrium and non-equilibrium fluctuations for applications in thermal photonics.

description: Contact tracing via digital tracking applications installed on mobile phones is an important tool for controlling epidemic spreading. Its effectivity can be quantified by modifying the standard methodology for analyzing percolation and connectivity of contact networks. We apply this framework to networks with varying degree distributions, numbers of application users, and probabilities of quarantine failures. Further, we study structured populations with homophily and heterophily and the possibility of degree-targeted application distribution. Our results are based on a combination of explicit simulations and mean-field analysis. They indicate that there can be major differences in the epidemic size and epidemic probabilities which are equivalent in the normal SIR processes. Further, degree heterogeneity is seen to be especially important for the epidemic threshold but not as much for the epidemic size. The probability that tracing leads to quarantines is not as important as the application adoption rate. Finally, both strong homophily and especially heterophily with regard to application adoption can be detrimental. Overall, epidemic dynamics are very sensitive to all of the parameter values we tested out, which makes the problem of estimating the effect of digital contact tracing an inherently multidimensional problem.

description: Vehicle re-identification helps in distinguishing between images of the same and other vehicles. It is a challenging process because of significant intra-instance differences between identical vehicles from different views and subtle inter-instance differences between similar vehicles. To solve this issue, researchers have extracted view-aware or part-specific features via spatial attention mechanisms, which usually result in noisy attention maps or otherwise require expensive additional annotation for metadata, such as key points, to improve the quality. Meanwhile, based on the researchers' insights, various handcrafted multi-attention architectures for specific viewpoints or vehicle parts have been proposed. However, this approach does not guarantee that the number and nature of attention branches will be optimal for real-world re-identification tasks. To address these problems, we proposed a new vehicle re-identification network based on a multiple soft attention mechanism for capturing various discriminative regions from different viewpoints more efficiently. Furthermore, this model can significantly reduce the noise in spatial attention maps by devising a new method for creating an attention map for insignificant regions and then excluding it from generating the final result. We also combined a channel-wise attention mechanism with a spatial attention mechanism for the efficient selection of important semantic attributes for vehicle re-identification. Our experiments showed that our proposed model achieved a state-of-the-art performance among the attention-based methods without metadata and was comparable to the approaches using metadata for the VehicleID and VERI-Wild datasets.

description: At the European Union level, the management of forced migration combines elements of the policy on external-border control and instruments of the Common European Asylum System. This article aims to examine how some of the strategies applied by States in order to fight illegal immigration and one of the instruments of the policy on asylum, the Dublin system, strike a delicate balance between security and human rights. It will be argued that these strategies and normative instruments may hinder the right to seek asylum in a safe country, and that a fairer and more equitable system for sharing responsibilities should be developed.

description: In this paper, we study how to efficiently and reliably detect active devices and estimate their channels in a multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) based grant-free non-orthogonal multiple access (NOMA) system to enable massive machine-type communications (mMTC). First, by exploiting the correlation of the channel frequency responses in narrow-band mMTC, we propose a block-wise linear channel model. Specifically, the continuous OFDM subcarriers in the narrow-band are divided into several sub-blocks and a linear function with only two variables (mean and slope) is used to approximate the frequency-selective channel in each sub-block. This significantly reduces the number of variables to be determined in channel estimation and the sub-block number can be adjusted to reliably compensate the channel frequency-selectivity. Second, we formulate the joint active device detection and channel estimation in the block-wise linear system as a Bayesian inference problem. By exploiting the block-sparsity of the channel matrix, we develop an efficient turbo message passing (Turbo-MP) algorithm to resolve the Bayesian inference problem with near-linear complexity. We further incorporate machine learning approaches into Turbo-MP to learn unknown prior parameters. Numerical results demonstrate the superior performance of the proposed algorithm over state-of-the-art algorithms.

Year: 2023

description: Robber flies are a species-rich family of insects and, therefore, pose a challenge for biodiversity research. Museum collections can help to shed light on diversity patterns and to tackle ecological questions. However, in order to be used by the scientific community, collections need to be visible and accessible. Here we present the previously unidentified Asilidae specimens collected in Japan held in the collections of the Zoologisches Forschungsmuseum Alexander Koenig, Bonn, Germany. Our material was collected by Bradley Sinclair during the 1990ies using a hand net and by Alexander Blanke between 2014 and 2016 using Malaise traps. We identified 334 individuals belonging to 20 named species and one unnamed taxon. Altogether, these holdings represent 19.4% of the known Japanese asilid fauna. Malaise traps used by Blanke were placed at the Sugadaira Research Station of the University of Tsukuba, Ueda, Nagano, and they sampled 16 species (15.4% of the Japanese fauna). The collection of Sinclair stems mainly from Kyushu Island. Stichopogon gracilifemur Nagatomi, 1983 is recorded for the first time from the island of Kyushu. All recorded species are featured with high-quality color images and information on synonymy, types, literature and distribution is also provided.

description: Ce mémoire a pour but de décrire des observations faites lors de cours de littérature en langue seconde (allemand). En effet, la littérature est de nos jours l’un des objets principaux dans l’enseignement des langues étrangères au niveau de la maturité fédérale. De ce fait, il paraît légitime de s’interroger sur les différentes modalités de la didactique de la littérature qui favoriseraient l’apprentissage d’une langue étrangère. Pour ce faire, le présent travail fera l’objet d’une comparaison entre deux approches didactiques bien différentes : d’une part il décrira les procédés correspondant à une approche plus traditionnelle (plus de style universitaire) et de l’autre il révélera les caractéristiques de l’approche actionnelle (enseignement par tâches). Après le recensement des représentations, habitudes de lecture et difficultés des élèves en ce qui concerne la littérature en classe de L2, l’auteure décrira une séquence d’enseignement de chaque approche et en fera une comparaison à base de questionnaires et observations afin de pouvoir visualiser les avantages et inconvénients de chacune d’entre elles. Finalement, les activités de l’approche actionnelle ayant aboutit à la création d’une bande dessinée, elle y mentionnera les bienfaits de l’emploi d’images et symboles non-verbaux pour soutenir la compréhension de manière holistique.

description: By estimating the Turaev genus or the dealternation number, which leads to an estimate of knot floer thickness, in terms of the genus and the braid index, we show that a knot $K$ in $S^{3}$ does not admit purely cosmetic surgery whenever $g(K)\geq \frac{3}{2}b(K)$, where $g(K)$ and $b(K)$ denotes the genus and the braid index, respectively. In particular, this establishes a finiteness of purely cosmetic surgeries; for fixed $b$, all but finitely many knots with braid index $b$ satisfies the cosmetic surgery conjecture.

description: Several applications of artificially modeled drivers, such as autonomous vehicles (AVs) or surrounding traffic in driving simulations, aim to provide not only functional but also human-like behavior. The development of human-like AVs is expected to improve the interaction between AVs and humans in traffic, whereas, in a driving simulation, the objective is to create realistic replicas of real driving scenarios to investigate various research questions under safe and reproducible conditions. In urban traffic, driving behavior strongly depends on the situational context, which introduces new challenges not only for modeling but also for the evaluation of such models. However, current objective assessment strategies rarely consider situational context and human similarity, whereas subjective approaches are not suitable for iterative development processes. In this paper, we present a first attempt to make the plausibility and human-likeness of vehicles’ trajectories objectively measurable. A multidimensional quality function is presented that incorporates various parameters characterizing human-like driving behavior and compares each of those parameters to human driving behavior under similar conditions. Among other things, our validation results show that the presented evaluation methodology is scalable to a wide range of situations has the ability to identify model weaknesses, and is able to reflect the way people distinguish between artificial and human behavior.

description: We explicitly compute the dynamics of closed homogeneous and isotropic universes permeated by a single perfect fluid with a constant equation of state parameter $w$ in the context of a recent reformulation of general relativity, proposed in [1], which prevents the vacuum energy from acting as a gravitational source. This is done using an iterative algorithm, taking as an initial guess the background cosmological evolution obtained using standard general relativity in the absence of a cosmological constant. We show that, in general, the impact of the vacuum energy sequestering mechanism on the dynamics of the universe is significant, except for the $w=1/3$ case where the results are identical to those obtained in the context of general relativity with a null cosmological constant. We also show that there are well behaved models in general relativity that do not have a well behaved counterpart in the vacuum energy sequestering paradigm studied in this paper, highlighting the specific case of a quintessence scalar field with a linear potential.

description: The behavior of the leading singular values and vectors of noisy low-rank matrices is fundamental to many statistical and scientific problems. Theoretical understanding currently derives from asymptotic analysis under one of two regimes: (1) the classical regime, with a fixed number of rows and large number of columns, or vice versa, and (2) the proportional regime, with large numbers of rows and columns, proportional to one another. This paper is concerned with the disproportional regime, where the matrix is either ``tall and narrow'' or ``short and wide'': we study sequences of matrices of size $n \times m_n$ with aspect ratio $ n/m_n \rightarrow 0$ or $n/m_n \rightarrow \infty$ as $n \rightarrow \infty$. This regime has important ``big data'' applications. Theory derived here shows that the displacement of the empirical singular values and vectors from their noise-free counterparts and the associated phase transitions -- well-known under proportional growth asymptotics -- still occur in the disproportionate setting. They must be quantified, however, on a novel scale of measurement that adjusts with the changing aspect ratio as the matrix size increases. In this setting, the top singular vectors corresponding to the longer of the two matrix dimensions are asymptotically uncorrelated with the noise-free signal.

description: Intéresser les élèves au droit pénal des mineurs peut sembler être une gageure, tant leur indifférence vis-à-vis de cette matière paraît profonde, convaincue de ne pas être concernés par de possibles conséquences de leurs actes car protégés par le statut de mineur. De même, l’apprentissage du droit est souvent perçu comme rébarbatif, ils subissent plutôt que de s’impliquer. S’il est une difficulté récurrente dans la transposition des savoirs, c’est bien celle d’obtenir l’attention sans faille d’un auditoire représenté par une classe de jeunes adolescents. L’apprentissage concret du DPMin va dépendre du degré d’implication des élèves dans la compréhension des mécanismes législatifs d’une part, et leurs capacités à critiquer un raisonnement juridique d’autre part. Les travaux de groupes, l’interaction entre les élèves et le jeu de rôle vont être des facteurs déterminants dans l’établissement d’une séquence de pédagogie active, mais la capacité de guidage exercée par l’enseignant risque de rencontrer certaines limites. C’est ici qu’intervient la venue d’un professionnel, le juge, en charge de l’application du DPMin, dont l’autorité en la matière ne souffrira d’aucun doute de la part de l’ensemble de la classe. Sa présence va être l’opportunité de relier la théorie à la pratique en mettant l’accent sur les difficultés rencontrées lors d’une procédure de jugement, mais surtout la volonté de protection et de resocialisation des adolescents qui a animé la refonte du DPMin en 2007. Un jeu de rôle traitant du DPMin et imaginé à partir de faits réels va amener l’élève à s’impliquer davantage en faisant appel à ses propres expériences, victime ou bourreau ! Nous voulons que nos classes construisent leur apprentissage par le biais d’activités originales telles qu’un jeu de rôle par exemple, pour favoriser leur réflexion et leur capacité à concevoir une argumentation. L’espace d’une séquence d’enseignement, les élèves vont pouvoir appréhender les rôles de victimes, d’accusés et de juges. Outre l’acquisition de connaissances juridiques, ce dispositif d’enseignement va permettre de favoriser une prise de conscience de l’élève concernant son comportement au sein ou en dehors de l’école. Eduquer, voilà la passerelle reliant le DPMin à celui de l’enseignement.

description: Esta investigación evalúa la accesibilidad peatonal hacia las paradas de transporte público. Esta evaluación se realizó a través de indicadores que representen la interacción de los peatones con el entorno urbano de las paradas, aplicado en un caso de estudio en concreto, que son las paradas con mayor índice de ascensos y descensos dentro del sistema de transporte de la ciudad de La Paz, Baja California Sur. El estudio y evaluación de la componente peatonal del tránsito, es pertinente en los entornos urbanos de las paradas de transporte pues supone un nuevo planteamiento sobre los factores que intervienen en el transporte público más allá de las rutas y las unidades de transporte, para la mejora de la movilidad y su integración urbana.

description: Let $M$ be the $6$-manifold $M$ as the total space of the sphere bundle of a rank $3$ vector bundle over a simply connected closed $4$-manifold. We show that after looping $M$ is homotopy equivalent to a product of loops on spheres in general. This particularly implies the cohomology rigidity property of $M$ after looping. Furthermore, passing to the rational homotopy, we show that such $M$ is Koszul in the sense of Berglund.

description: We search Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3) broadband imaging data from the Panchromatic Hubble Andromeda Treasury (PHAT) survey to identify detections of cataloged planetary nebulae (PNe). Of the 711 PNe currently in the literature within the PHAT footprint, we find 467 detected in the broadband. For these 467 we are able to refine their astrometric accuracy from ~0."3 to 0."05. Using the resolution of HST, we are able to show that 152 objects currently in the catalogs are definitively not PNe, and we show that 32 objects thought to be extended in ground-based images are actually point-like and therefore good PN candidates. We also find one PN candidate that is marginally resolved. If this is a PN, it is up to 0.7 pc in diameter. With our new photometric data, we develop a method of measuring the level of excitation in individual PNe by comparing broadband and narrowband imaging and describe the effects of excitation on a PN's photometric signature. Using the photometric properties of the known PNe in the PHAT catalogs, we search for more PN, but do not find any new candidates, suggesting that ground-based emission-line surveys are complete in the PHAT footprint to F475W $\simeq$ 24.

description: We consider platoons composed of identical vehicles and controlled in a distributed way, that is, each vehicle has its own onboard controller. The regulation errors in spacing to the immediately preceeding and following vehicles are weighted differently by the onboard controller, which thus implements an asymmetric bidirectional control scheme. The weights can vary along the platoon. We prove that such platoons have a nonzero uniform bound on the second smallest eigenvalue of the graph Laplacian matrix - the Fiedler eigenvalue. Furthermore, it is shown that existence of this bound always signals undesirable scaling properties of the platoon. Namely, the H-infinity norm of the transfer function of the platoon grows exponentially with the number of vehicles regardless of the controllers used. Hence the benefits of a uniform gap in the spectrum of a Laplacian with an asymetric distributed controller are paid for by poor scaling as the number of vehicles grows.

description: Damping of longitudinal coherent bunched-beam oscillations are needed in SIS18 and SIS100 to stabilize the beam, prevent emittance growth and keep beamloss low during acceleration. In last year’s work several approaches of digital filters for beam-phase control have been examined. An FIR (finite impulse response) filter with 3 taps, cf. [1], has been successfully used at GSI in several machine experiments for a beam- phase control system and a longitudinal feedback system. In principle, much more taps can be used, but it is still an open topic, whether more complex filters will lead to better results. Therefore, a detailed control-theoretic study has been started and the progress is reported in the following.
Interval Forecasting of Electricity Demand: A Novel Bivariate EMD-based Support Vector Regression Modeling Framework

description: Highly accurate interval forecasting of electricity demand is fundamental to the success of reducing the risk when making power system planning and operational decisions by providing a range rather than point estimation. In this study, a novel modeling framework integrating bivariate empirical mode decomposition (BEMD) and support vector regression (SVR), extended from the well-established empirical mode decomposition (EMD) based time series modeling framework in the energy demand forecasting literature, is proposed for interval forecasting of electricity demand. The novelty of this study arises from the employment of BEMD, a new extension of classical empirical model decomposition (EMD) destined to handle bivariate time series treated as complex-valued time series, as decomposition method instead of classical EMD only capable of decomposing one-dimensional single-valued time series. This proposed modeling framework is endowed with BEMD to decompose simultaneously both the lower and upper bounds time series, constructed in forms of complex-valued time series, of electricity demand on a monthly per hour basis, resulting in capturing the potential interrelationship between lower and upper bounds. The proposed modeling framework is justified with monthly interval-valued electricity demand data per hour in Pennsylvania-New Jersey-Maryland Interconnection, indicating it as a promising method for interval-valued electricity demand forecasting.

description: To deploy the airframe digital twin or to conduct probabilistic evaluations of the remaining life of a structural component, a (near) real-time crack-growth simulation method is critical. In this paper, a reduced-order simulation approach is developed to achieve this goal by leveraging two methods. On the one hand, the symmetric Galerkin boundary element method - finite element method (SGBEM-FEM) coupling method is combined with parametric modeling to generate the database of computed stress intensity factors for cracks with various sizes/shapes in a complex structural component, by which hundreds of samples are automatically simulated within a day. On the other hand, machine learning methods are applied to establish the relation between crack sizes/shapes and crack-front stress intensity factors. By combining the reduced-order computational model with load inputs and fatigue growth laws, a real-time prediction of probabilistic crack growth in complex structures with minimum computational burden is realized. In an example of a round-robin helicopter component, even though the fatigue crack growth is simulated cycle by cycle, the simulation is faster than real-time (as compared with the physical test). The proposed approach is a key simulation technology toward realizing the digital twin of complex structures, which further requires fusion of model predictions with flight/inspection/monitoring data.

description: El estudio e implementación ́on de controladores en sistemas mec ́anicos es fundamental para su optimización ́on y desempeño ̃no en lazo cerrado. Todo sistema mec ́anico en lazo cerrado requiere que sus actuadores sean manipulados por un algoritmo de control. Optimizar estos algoritmos es de gran inter ́es para la industria, ya que representa ahorro de recursos, por ́esto, continua- mente se busca implementar nuevas formas de hacer los algoritmos de control más robustos, precisos y rápidos. Este trabajo se enfoca en implementar algoritmos de control para el se- guimiento de trayectoria en sistemas mec ́anicos, con el fin de evaluar resul- tados pr ́acticos y de simulaci ́on. Este tipo de controlador Terminal Sliding Mode (TSM, por sus siglas en ingl ́es), tiene un comportamiento robusto, ya que puede reaccionar ante incertidumbres param ́etricas y perturbaciones externas en el sistema y adaptarse para asegurar convergencia en tiempo finito. El control es basado en compensaciones de error utilizando modos deslizantes.
