    “Artworks are not being but a process of becoming” —Theodor W. Adorno, Aesthetic Theory In the everyday use of the concept, saying that something is grotesque rarely implies anything other than saying that something is a bit outside of the normal structure of language or meaning – that something is a peculiarity. But in its historical use the concept has often had more far reaching connotations. In different phases of history the grotesque has manifested its forms as a means of (...)

    Dynamic Learning from Adaptive Neural Control of Uncertain Robots with Guaranteed Full-State Tracking Precision.Min Wang, Yanwen Zhang & Huiping Ye - 2017 - Complexity 2017:1-14.
    A dynamic learning method is developed for an uncertain n-link robot with unknown system dynamics, achieving predefined performance attributes on the link angular position and velocity tracking errors. For a known nonsingular initial robotic condition, performance functions and unconstrained transformation errors are employed to prevent the violation of the full-state tracking error constraints. By combining two independent Lyapunov functions and radial basis function neural network approximator, a novel and simple adaptive neural control scheme is proposed for the dynamics (...)

  4. Dynamics of nonlinear feedback control.H. Snippe & J. H. van Hateren - 1996 - In Enrique Villanueva (ed.), Perception. Ridgeview Pub. Co. pp. 182-182.
    Feedback control in neural systems is ubiquitous. Here we study the mathematics of nonlinear feedback control. We compare models in which the input is multiplied by a dynamic gain (multiplicative control) with models in which the input is divided by a dynamic attenuation (divisive control). The gain signal (resp. the attenuation signal) is obtained through a concatenation of an instantaneous nonlinearity and a linear low-pass filter operating on the output of the feedback loop. For input steps, (...)

    Asynchronous Stabilization of Nonlinear Markov Jump Singularly Perturbed Systems via Fuzzy Static Output Feedback Control.Baogang Ding, Tingting Ma, Xiaoxin Feng & Yueying Wang - 2021 - Complexity 2021:1-10.
    This study focuses on the static output feedback control of nonlinear Markov jump singularly perturbed systems within the framework of Takagi–Sugeno fuzzy approximation. From a practical point of view, the phenomenon of asynchronous switching between the plant and the controller is considered and characterized by a finite piecewise-homogenous Markov process. Particularly, for facilitating the controller synthesis, the closed-loop system is transformed into a fuzzy Markov jump singularly perturbed descriptor system by adopting descriptor representation. In order to fully (...)

  6. Cosmic Pessimism.Eugene Thacker - 2012 - Continent 2 (2):66-75.
    continent. 2.2 (2012): 66–75 ~*~ We’re Doomed. Pessimism is the night-side of thought, a melodrama of the futility of the brain, a poetry written in the graveyard of philosophy. Pessimism is a lyrical failure of philosophical thinking, each attempt at clear and coherent thought, sullen and submerged in the hidden joy of its own futility. The closest pessimism comes to philosophical argument is the droll and laconic “We’ll never make it,” or simply: “We’re doomed.” Every effort doomed to failure, every (...)

    Event-Triggered Consensus Control for Leader-Following Multiagent Systems Using Output Feedback.Yang Liu & Xiaohui Hou - 2018 - Complexity 2018:1-9.
    The event-triggered consensus control for leader-following multiagent systems subjected to external disturbances is investigated, by using the output feedback. In particular, a novel distributed event-triggered protocol is proposed by adopting dynamic observers to estimate the internal state information based on the measurable output signal. It is shown that under the developed observer-based event-triggered protocol, multiple agents will reach consensus with the desired disturbance attenuation ability and meanwhile exhibit no Zeno behaviors. Finally, a simulation is presented to (...)

    Output Feedback Model Predictive Control for NCSs with Input Quantization.Hongchun Qu, Yu Li & Wei Liu - 2022 - Complexity 2022:1-20.
    This paper addresses the robust output feedback model predictive control schemes for networked control systems with input quantization. The logarithmic quantizer is considered in this paper, and the sector bound approach is applied, which appropriately treats the quantization error as a sector-bounded uncertainty. The presented method involves an offline designed state observer using linear matrix inequality and online robust output feedback MPC algorithms which optimize one free control move followed by the output feedback (...)

    Output Feedback Recursive Dynamic Surface Control with Antiwindup Compensation.Guofa Sun, Hui Du, Gang Wang & Hanbo Yu - 2021 - Complexity 2021:1-16.
    Actuator saturation phenomenon often exists in the actual control system, which could destroy the closed-loop performance of the system and even lead to unstable behavior. Our main contribution is to provide an antiwindup recursive dynamic surface control for a discrete-time system with an unknown state and actuator saturation. The fuzzy compensator is added to perform as an active disturbance rejection term in the feedforward path to avoid windup caused by input saturation. To construct output feedback control, the (...)

    Finite-Time Tracking Control for Nonstrict-Feedback State-Delayed Nonlinear Systems with Full-State Constraints and Unmodeled Dynamics.Yangang Yao, Jieqing Tan & Jian Wu - 2020 - Complexity 2020:1-18.
    The problem of finite-time tracking control is discussed for a class of uncertain nonstrict-feedback time-varying state delay nonlinear systems with full-state constraints and unmodeled dynamics. Different from traditional finite-control methods, a C 1 smooth finite-time adaptive control framework is introduced by employing a smooth switch between the fractional and cubic form state feedback, so that the desired fast finite-time control performance can be guaranteed. By constructing appropriate Lyapunov-Krasovskii functionals, the uncertain terms produced by time-varying (...)

    Neural Network-Based Output Feedback Fault Tolerant Tracking Control for Nonlinear Systems with Unknown Control Directions.Kun Yan, Chaobo Chen, Xiaofeng Xu & Qingxian Wu - 2022 - Complexity 2022:1-14.
    In this study, an adaptive output feedback fault tolerant control scheme is proposed for a class of multi-input and multioutput nonlinear systems with multiple constraints. The neural network is adopted to handle the unknown nonlinearity by means of its superior approximation capability. Based on it, the state observer is designed to estimate the unmeasured states, and the nonlinear disturbance observer is constructed to tackle the external disturbances. In addition, the Nussbaum function is utilized to cope with the (...)

    State feedback based on grey wolf optimizer controller for two-wheeled self-balancing robot.Wesam M. Jasim - 2022 - Journal of Intelligent Systems 31 (1):511-519.
    The two-wheeled self-balancing robot is based on the axletree and inverted pendulum. Its balancing problem requires a control action. To speed up the response of the robot and minimize the steady state error, in this article, a grey wolf optimizer method is proposed for TWSBR control based on state space feedback control technique. The controller stabilizes the balancing robot and minimizes the overshoot value of the system. The dynamic model of the system is derived based on Euler (...)

    Reflection machines: increasing meaningful human control over Decision Support Systems.W. F. G. Haselager, H. K. Schraffenberger, R. J. M. van Eerdt & N. A. J. Cornelissen - 2022 - Ethics and Information Technology 24 (2).
    Rapid developments in Artificial Intelligence are leading to an increasing human reliance on machine decision making. Even in collaborative efforts with Decision Support Systems (DSSs), where a human expert is expected to make the final decisions, it can be hard to keep the expert actively involved throughout the decision process. DSSs suggest their own solutions and thus invite passive decision making. To keep humans actively ‘on’ the decision-making loop and counter overreliance on machines, we propose a ‘reflection machine’ (RM). This (...)

    Nonfragile H ∞ Stabilizing Nonlinear Systems Described by Multivariable Hammerstein Models.Zeineb Rayouf, Chekib Ghorbel & Naceur Benhadj Braiek - 2021 - Complexity 2021:1-12.
    This paper presents the problem of robust and nonfragile stabilization of nonlinear systems described by multivariable Hammerstein models. The objective is focused on the design of a nonfragile feedback controller such that the resulting closed-loop system is globally asymptotically stable with robust H ∞ disturbance attenuation in spite of controller gain variations. First, the parameters of linear and nonlinear blocks characterizing the multivariable Hammerstein model structure are separately estimated by using a subspace identification algorithm. Second, approximate inverse nonlinear functions (...)

    Social Choice Should Guide AI Alignment in Dealing with Diverse Human Feedback.Vincent Conitzer, Rachel Freedman, Jobst Heitzig, Wesley H. Holliday, Bob M. Jacobs, Nathan Lambert, Milan Mosse, Eric Pacuit, Stuart Russell, Hailey Schoelkopf, Emanuel Tewolde & William S. Zwicker - forthcoming - Proceedings of the Forty-First International Conference on Machine Learning.
    Foundation models such as GPT-4 are fine-tuned to avoid unsafe or otherwise problematic behavior, such as helping to commit crimes or producing racist text. One approach to fine-tuning, called reinforcement learning from human feedback, learns from humans' expressed preferences over multiple outputs. Another approach is constitutional AI, in which the input from humans is a list of high-level principles. But how do we deal with potentially diverging input from humans? How can we aggregate the input into consistent data about (...)

    Robust H∞ Control for Markovian-Jump-Parameters Takagi–Sugeno Fuzzy Systems.Wenzhao Qin, Yukai Shen & Lifang Wang - 2022 - Complexity 2022:1-10.
    The H ∞ performance of a class of T-S fuzzy systems with Markovian-jump parameters is analyzed. A state feedback controller is designed for T-S fuzzy systems with Markovian-jump parameters. First, a new modal-dependent Lyapunov function composed of closed-loop functions is constructed, which can fully use system status information. Based on this function, the stability conditions with less conservatism are given by linear matrix inequalities. At the same time, a design algorithm for a state feedback controller is (...)

    A real-time fMRI neurofeedback system for the clinical alleviation of depression with a subject-independent classification of brain states: A proof of principle study.Jaime A. Pereira, Andreas Ray, Mohit Rana, Claudio Silva, Cesar Salinas, Francisco Zamorano, Martin Irani, Patricia Opazo, Ranganatha Sitaram & Sergio Ruiz - 2022 - Frontiers in Human Neuroscience 16.
    Most clinical neurofeedback studies based on functional magnetic resonance imaging use the patient's own neural activity as feedback. The objective of this study was to create a subject-independent brain state classifier as part of a real-time fMRI neurofeedback system that can guide patients with depression in achieving a healthy brain state, and then to examine subsequent clinical changes. In a first step, a brain classifier based on a support vector machine was trained from the neural information of (...)

    Robust H ∞ Feedback Compensator Design for Linear Parabolic DPSs with Pointwise/Piecewise Control and Pointwise/Piecewise Measurement.Liu Yaqiang, Ren Zhigang & Jin Zengwang - 2021 - Complexity 2021:1-14.
    In this paper, a robust H ∞ control problem of a class of linear parabolic distributed parameter systems with pointwise/piecewise control and pointwise/piecewise measurement has been investigated via the robust H ∞ feedback compensator design approach. A unified Lyapunov direct approach is proposed in consideration of the pointwise/piecewise control and point/piecewise measurement based on the distributions of the actuators and sensors. A new type of Luenberger observer is developed on the continuous interval of space domain to track the (...) of the system, and an H ∞ performance constraint with prescribed H ∞ attenuation levels is proposed in this paper. By utilizing Lyapunov technique, mathematical inequalities, and integration theory, a sufficient condition based on LMI for the exponential stability of the corresponding closed-loop coupled system under an H ∞ performance constraint is presented. Finally, the effectiveness of the proposed design method is verified by numerical simulation results. (shrink)

    Employees Adhere More to Unethical Instructions from Human Than AI Supervisors: Complementing Experimental Evidence with Machine Learning.Lukas Lanz, Roman Briker & Fabiola H. Gerpott - 2023 - Journal of Business Ethics 189 (3):625-646.
    The role of artificial intelligence (AI) in organizations has fundamentally changed from performing routine tasks to supervising human employees. While prior studies focused on normative perceptions of such AI supervisors, employees’ behavioral reactions towards them remained largely unexplored. We draw from theories on AI aversion and appreciation to tackle the ambiguity within this field and investigate if and why employees might adhere to unethical instructions either from a human or an AI supervisor. In addition, we identify employee characteristics affecting this (...)

    Robust H ∞ Control of DC Motor in the Presence of Input Delay and Disturbance by the Predictor-Based Method.Nima Maleki & Elahe Moradi - 2022 - Complexity 2022:1-10.
    In this study, the speed control of a DC motor with input delay and external disturbance is investigated. A delay-dependent memory state feedback robust predictor-based H ∞ controller that formerly has presented is utilized. Sufficient LMIs conditions provide the stabilizing gain of the predictor-based controller. The first-order model of a DC motor has been studied previously using PID and STA methods. However, in this paper, the delay-dependent robust H ∞ controller is used on both the first and second (...)

    This commentary discusses three features of the general theoretical framework proposed by Nunez: (1) Functional concepts, such as computation and control, are not foundational. (2) A mismatch between the concept of subcortical input and EEG output is problematic for the input/output operator concept of cortical dynamics. (3) The concept of brain state is relatively static.

    Mood state, task demand, and effort-related cardiovascular response.Guido H. E. Gendolla & Jan Krüsken - 2002 - Cognition and Emotion 16 (5):577-603.
    Drawing on the mood-behaviour model (Gendolla, 2000), two studies investigated informational effects of mood on effort-related cardiovascular response. Experiment 1 manipulated mood state (positive, negative) and task difficulty (easy, difficult, extremely difficult). Effects on cardiovascular reactivity were as expected: On the easy level, reactivity was weak in a positive mood, but strong in a negative mood; on the difficult level, reactivity was strong in a positive mood, but weak in a negative mood; on the extremely difficulty level mood had (...)

This separation is named the epistemic cut, and explaining clearly how the stands-for relation is (...)

    The phenomenology of controlled action depends on comparisons between predicted and actually perceived sensory feedback called action-effects. We investigated if intervening task-irrelevant but semantically related information influences monitoring processes that give rise to a sense of control. Participants judged whether a moving box “obeyed” or “disobeyed” their own arrow keystrokes or visual cues representing the computer’s choices . During 1 s delays between keystrokes/cues and box movements, participants vocalized directions cued by letters inside the box. Congruency of cued vocalizations (...)

    The mind-body relation or, more particularly, the mind-brain relation 1 has been a perennial puzzle for philosophers—how can things so different be intimately related? Husserl dealt with the mind-brain relation in Section 63 of Ideen II, “Psychophysischer Parallelismus and Wechselwirkung,” 2 where he gave a critique of psychophysical parallelism. For Husserl, the mind-brain relation is to be understood not as a material or metaphysical relation, but as a relation between the presented sense or significance of two varieties of appearances. Husserl’s (...)

    The two theories that revolutionized physics in the twentieth century, relativity and quantum mechanics, are full of predictions that defy common sense. Recently, we used three such paradoxical ideas to prove “The Free Will Theorem” (strengthened here), which is the culmination of a series of theorems about quantum mechanics that began in the 1960s. It asserts, roughly, that if indeed we humans have free will, then elementary particles already have their own small share of this valuable commodity. More precisely, (...)

    Quantitatively characterizing reflexive responses to pitch perturbations.Elaine Kearney, Alfonso Nieto-Castañón, Riccardo Falsini, Ayoub Daliri, Elizabeth S. Heller Murray, Dante J. Smith & Frank H. Guenther - 2022 - Frontiers in Human Neuroscience 16:929687.
    BackgroundReflexive pitch perturbation experiments are commonly used to investigate the neural mechanisms underlying vocal motor control. In these experiments, the fundamental frequency–the acoustic correlate of pitch–of a speech signal is shifted unexpectedly and played back to the speaker via headphones in near real-time. In response to the shift, speakers increase or decrease their fundamental frequency in the direction opposing the shift so that their perceived pitch is closer to what they intended. The goal of the current work is to develop (...)

    Perhaps nothing symbolizes the current polarized political climate in the United States more than the world of public health. Public health schools and health departments are full of “true believers,” people willing to crusade for any program designed to reduce morbidity and mortality. But in the “real world,” proven programs and strategies—such as gun-control measures, universal vaccination, and improved traffic safety—are routinely thwarted. Why do critics oppose efforts to improve the public's health? History can provide some answers.

    This study first investigates robust iterative learning control issue for a class of two-dimensional linear discrete singular Fornasini–Marchesini systems under iteration-varying boundary states. Initially, using the singular value decomposition theory, an equivalent dynamical decomposition form of 2-D LDSFM is derived. A simple P-type ILC law is proposed such that the ILC tracking error can be driven into a residual range, the bound of which is relevant to the bound parameters of boundary states. Specially, while the boundary states of 2-D LDSFM (...)

    Ethical considerations for DNA testing as a proxy for nationality.Valedie Oray & Sara H. Katsanis - 2021 - Global Bioethics 32 (1):51-66.
    As nations strengthen borders and restrict refugee admissions, national security officials are screening for fraudulent nationality claims. One tool to investigate nationality claims is DNA testing, either for claimed relationships or for ancestral origins. At the same time, the plight of global statelessness leaves millions without documentation of their nationality, and DNA testing might be the only recourse to provide evidence of heritage or relationships. DNA testing has been used sparsely to date to determine ancestral origin as a proxy for (...)

    Dynamic Analysis and Degenerate Hopf Bifurcation-Based Feedback Control of a Conservative Chaotic System and Its Circuit Simulation.Xiaojuan Zhang, Mingshu Chen, Yang Wang, Huaigu Tian & Zhen Wang - 2021 - Complexity 2021:1-15.
    A novel conservative chaotic system with no equilibrium is investigated in this study. Various dynamics such as the conservativeness, coexistence, symmetry, and invariance are presented. Furthermore, a partial-state feedback control scheme is proposed, and the stable domain of control parameters is analyzed based on the degenerate Hopf bifurcation. In order to verify the numerical simulation analysis, an analog circuit is designed. The simulation results show that the output of the analog circuit system can reproduce the numerical simulation (...)

    Optimal Control for Networked Control Systems with Markovian Packet Losses.Xiao Han, Zhijian Ji & Qingyuan Qi - 2020 - Complexity 2020:1-11.
    This paper is concerned with the optimal output feedback control problem for networked control systems with Markovian packet losses. In this paper, the packet losses occur both between the sensor and controller and between the controller and actuator. Moreover, the packet loss channels are described with two-state Markov chains. Since the precise state information cannot be obtained, thus an optimal recursive estimator is designed. Furthermore, by adopting the dynamic programming approach, we derive the optimal output (...)

    This piece, included in the drift special issue of continent. , was created as one step in a thread of inquiry. While each of the contributions to drift stand on their own, the project was an attempt to follow a line of theoretical inquiry as it passed through time and the postal service(s) from October 2012 until May 2013. This issue hosts two threads: between space & place and between intention & attention . The editors recommend that to experience the (...)

    An approach to deciding the observational equivalence of Algol-like languages.C. -H. L. Ong - 2004 - Annals of Pure and Applied Logic 130 (1-3):125-171.
    We prove that the observational equivalence of third-order finitary Idealized Algol is decidable using Game Semantics. By modelling the state explicitly in our games, we show that the denotation of a term M of this fragment of IA is a compactly innocent strategy-with-state, i.e. the strategy is generated by a finite view function fM. Given any such fM, we construct a real-time deterministic pushdown automaton that recognizes the complete plays of the knowing-strategy denotation of M. Since such plays (...)

    There are four types of information an agent can have concerning the state of the universe: information acquired via observation, via control, via prediction, or via retrodiction, i.e., memory. Each of these four types of information appear to rely on a different kind of physical device. However it turns out that there is some mathematical structure that is common to those four types of devices. Any device that possesses that structure is known as an “inference device”. Here I review (...)

    The Ties That Bind: University Nostalgia Fosters Relational and Collective University Engagement.Jeffrey D. Green, Athena H. Cairo, Tim Wildschut & Constantine Sedikides - 2021 - Frontiers in Psychology 11.
    Does nostalgia for one’s time at university predict current intentions to engage with the university? In Study 1, United States participants’ nostalgia for their university experience (university nostalgia) at a southern public university predicted stronger intentions to socialize with fellow alumni, attend a future reunion, volunteer for their university, and donate money to their university. Study 2 replicated these findings with alumni from a northeastern private university, and extended them by finding that the links between university nostalgia and university engagement (...)

    Brain state-dependent robotic reaching movement with a multi-joint arm exoskeleton: combining brain-machine interfacing and robotic rehabilitation.Daniel Brauchle, Mathias Vukelić, Robert Bauer & Alireza Gharabaghi - 2015 - Frontiers in Human Neuroscience 9:130134.
    While robot-assisted arm and hand training after stroke allows for intensive task-oriented practice, it has provided only limited additional benefit over dose-matched physiotherapy up to now. These rehabilitation devices are possibly too supportive during the exercises. Neurophysiological signals might be one way of avoiding slacking and providing robotic support only when the brain is particularly responsive to peripheral input. We tested the feasibility of three-dimensional robotic assistance for reach-to-grasp movements with a multi-joint exoskeleton during motor imagery-related desynchronization of sensorimotor oscillations (...)

    Don't tell terrible stories—everyone here has enough of their own. Everyone here has a whole bloody sack of terrible stories, and at the bottom of the sack is a hammer the narrator uses to pound you on the skull the instant you dare not believe your ears. Or to pound you when you do believe. Not long ago I saw a tomboyish girl on Khreshchatyk Street demand money of an elderly woman, threatening to bite her and infect her with syphilis. (...)
