Error Theory Research Articles

Do we have (in)compatibilist intuitions? Surveying experimental research.

This article critically examines the experimental philosophy of free will, particularly the interplay between ordinary individuals' compatibilist and incompatibilist intuitions. It explores key insights from research studies that propose "natural compatibilism" and "natural incompatibilism". These studies reveal a complex landscape of folk intuitions, where participants appear to exhibit both types of intuitions. Here, we examine error theories, which purport to explain the coexistence of apparently contradictory intuitions: the Affective Performance Error hypothesis, the "Free Will No Matter What" hypothesis, the Bypassing hypothesis, and the Intrusion hypothesis, and the article explores the cognitive errors that could shape individuals' inconsistent perceptions of free will. We then explore three possibilities regarding folk intuitions: most individuals may hold either compatibilist or incompatibilist intuitions, both simultaneously, or neither. Our aim is to deepen the understanding of the complex dynamics of intuitions about free will, and we close with suggestions for future studies in experimental philosophy.

Restricted nominalism about number and its problems

Hofweber (Ontology and the ambitions of metaphysics, Oxford University Press, 2016) argues for a thesis he calls “internalism” with respect to natural number discourse: no expressions purporting to refer to natural numbers in fact refer, and no apparent quantification over natural numbers actually involves quantification over natural numbers as objects. He argues that while internalism leaves open the question of whether other kinds of abstracta exist, it precludes the existence of natural numbers, thus establishing what he calls “restricted nominalism” about natural numbers. We argue that Hofweber’s internalism fails to establish restricted nominalism. Not only is his primary argument for restricted nominalism invalid, the analysis of quantification proposed threatens to collapse internalism into either a traditional form of error theory or realism.

Is Biological Aging a Treatable Disease? A Consideration Based on Proposed Mechanisms of Aging

In view of the current claim by many researchers that biological aging is a treatable disease, the possibility is discussed whether the claim is realistic, based on several proposed mechanisms of aging. The definition of biological aging is stated referring to physiological aging and pathological aging, since biological aging must be defined for the discussion of whether it can be cured. Aging in animal model is compared with that in humans in terms of common age-associated phenotypes. Major proposed mechanisms of aging are next examined including Genome Instability Theory of aging, Free Radical or Oxidative Stress Theory of Aging, Mitochondrial Theory of Aging, Error Catastrophe Theory of Aging/Translational Error Theory of Aging, Altered Protein Theory of Aging/Proteostasis Theory of Aging, and Epigenetic Theory of Aging. Finally, we discuss whether treatment of aging as a disease is realistic in comparison with possible lifespan extension by retardation of biological aging.

Inner speech and the body error theory.

Inner speech is commonly understood as the conscious experience of a voice within the mind. One recurrent theme in the scientific literature is that the phenomenon involves a representation of overt speech, for example, a representation of phonetic properties that result from a copy of speech instructions that were ultimately suppressed. I propose a larger picture that involves some embodied objects and their misperception. I call it "the Body Error Theory," or BET for short. BET is a form of illusionism, but the particular version I favor is a cross-modal illusion. Newly described here, my hypothesis is that the experience of inner speech arises from a mix of interoception and audition. Specifically, there is the detection of slight but well-confirmed activities in the speech musculature that occur during inner speech, which helps to transform representations of normal but quiet nonverbal sounds that inevitably occur during inner speech, from breathing to background noise, into a mistaken perception of inner speech. Simply put, activities in the speech musculature mix with sounds to create the appearance of speech sounds, which thus explains the "voice within the mind." I also show how BET's cross-modal system fits with standard information processing accounts for speech monitoring and how it accommodates the central insights of leading theories of inner speech. In addition, I show how BET is supported by data from experience-sampling surveys and how it can be empirically tested against its rivals.

Motion Error Mechanism Analysis and Simulation Verification of Ocean Electric Field Sensor

The electric field measurement based on Unmanned Underwater Vehicle (UUV) can monitor and evaluate real-time electric field of underwater targets in motion, which has the ability to adapt to harsh marine environments. However, electric field sensors generate new errors during underwater motion, and there is still absence of studies on the error theory and simulation. To address this, the error generation mechanism of Ag/AgCl electrodes induced by the flow field was analyzed in this paper. A coupled mathematical model of flow-chemical-electric multi-physical field was established for the first time, and finite element simulation analysis was carried out. The results show that the change value of electrode surface potential under the influence of flow rate is basically in agreement with the empirical formulae. R-squared value of the two fits reaches up to 0.968, and RMSE value is less than 0.003, confirming the robustness of the model and simulations. The multi-physical field coupling model and simulation method proposed in this paper can provide theoretical and methodological support for the design of electric field sensors and motion error correction.

Improvement of photogrammetric joint roughness coefficient value by integrating automatic shooting parameter selection and composite error model

In order to improve the accuracy of the photogrammetric joint roughness coefficient (JRC) value, the present study proposed a novel method combining an autonomous shooting parameter selection algorithm with a composite error model. Firstly, according to the depth map-based photogrammetric theory, the estimation of JRC from a three-dimensional (3D) digital surface model of rock discontinuities was presented. Secondly, an automatic shooting parameter selection algorithm was novelly proposed to establish the 3D model dataset of rock discontinuities with varying shooting parameters and target sizes. Meanwhile, the photogrammetric tests were performed with custom-built equipment capable of adjusting baseline lengths, and a total of 36 sets of JRC data was gathered via a combination of laboratory and field tests. Then, by combining the theory of point cloud coordinate computation error with the equation of JRC calculation, a composite error model controlled by the shooting parameters was proposed. This newly proposed model was validated via the 3D model dataset, demonstrating the capability to correct initially obtained JRC values solely based on shooting parameters. Furthermore, the implementation of this correction can significantly reduce errors in JRC values obtained via photographic measurement. Subsequently, our proposed error model was integrated into the shooting parameter selection algorithm, thus improving the rationality and convenience of selecting suitable shooting parameter combinations when dealing with target rock masses with different sizes. Moreover, the optimal combination of three shooting parameters was offered. JRC values resulting from various combinations of shooting parameters were verified by comparing them with 3D laser scan data. Finally, the application scope and limitations of the newly proposed approach were further addressed.

Python Software Tool for Diagnostics of the Global Navigation Satellite System Station (PS-NETM)–Reviewing the New Global Navigation Satellite System Time Series Analysis Tool

The time series of GNSS coordinates contain signals caused by the age-related movement of tectonic plates, the deformation of the Earth’s surface, as well as errors at different time scales from sub-daily tidal deformation to the long-term deformation of the surface load. Depending on the nature of the signal, specific approaches are used for both the visual interpretation and pre-processing of time series and their statistical analysis. However, none of the present software analyzes the nature of the residual errors but assumes their random nature and obedience to the classical normal distribution. One of the methods for analyzing the time series of coordinates with residual, unaccounted-for systematic errors is the non-classical error theory of measurements. The result of this work is a developed software solution for analyzing the time series of GNSS coordinates to test their normality, or in other words, to test whether a particular GNSS station is subject to the influence of small, unaccounted-for errors. Conclusions: After testing our software on four reference stations in Europe, we concluded that none of the chosen stations followed the normal law of distribution; thus, it is vital to perform such tests before conducting any experiments on the time series from reference stations.

A semantics for moral error theory

Abstract Moral error theory has been criticized on formal grounds for lacking a coherent semantics of moral sentences. In this paper, I provide a truthmaker-based semantics of moral sentences that is compatible with moral error theory. The hyperintensional account draws attention to the exact truth- and falsemakers of moral propositions. Error theorists must assume that propositions that have only moral truthmakers have at least one non-moral falsemaker. A central consequence of the discussion is that moral error theory is compatible with a classical logic of moral notions.

Normative Error Theory and No Self-Defeat: A Reply to Case

Many philosophers have claimed that normative error theorists are committed to the claim ‘Error theory is true, but I have no reason to believe it’, which to some appears paradoxical. Case (2019) has claimed that the normative error theorist cannot avoid this paradox. In this paper, we argue that there is no paradox in the first place, that is once we clear up the ambiguity of the word ‘reason’, both on the error theorist’s side and those that claim that there is a self-defeat problem. Upon clarification, we also raise scepticism to what exactly the nature of self-defeat is meant to be.

Investigation of the impact of cycloidal gear pin tooth wear on transmission error in precision planetary cycloidal reducers

In light of the alteration pattern of transmission error following wear of a cycloid gear and needle tooth, this study employs the precision planetary cycloidal 80E reducer as an example. Theoretical deduction and simulation analysis of the change in transmission error were conducted, relying on the Archard wear model and an error model. Utilizing the principles of Archard wear theory and error theory, a functional relationship between wear duration and transmission error is deduced. Subsequently, a dynamic simulation of the 3D model is executed using ADAMS software, and the simulation results are processed with MATLAB software. A comparative and analytical examination is conducted between the theoretical curve and the simulation curve of transmission error to explore the influence of the cycloid gear and needle tooth wear on transmission error. Finally, the precision of the simulation results is further confirmed through experimental validation. The findings revealed that the transmission error curve gradually increased during the initial wear of the cycloid gear and the needle tooth, with the rate of increase increasing proportionally with wear duration. By comparing the theoretical calculations, simulation outcomes, and experimental results, the validity and accuracy of the transmission error calculations grounded in Archard wear theory and error theory are confirmed. This research provides a theoretical basis for accurately predicting the survival of precision planetary cycloidal reducers throughout the lifespan.

THE DEVELOPMENT AND VALIDATION OF A TACTICAL GRADE EGI SYSTEM FOR LAND VEHICULAR NAVIGATION APPLICATIONS

Abstract. Over recent years, the utilization of commercially available integrated navigation systems for the development of navigation algorithms has become increasingly commonplace. Nevertheless, the wide range of sensor quality on the market complicates system customization and restricts the evolution of navigation algorithms. This study aims to address these issues by creating an affordable, tactical-grade, real-time integrated navigation system, EGI-500 (Embedded GNSS and INS), encompassing both hardware and software components. EGI-500 incorporates a tactical-grade IMU500 and a Septentrio Mosaic-X5 GNSS receiver module. The integration process is segmented into three distinct stages. The first involves hardware integration, with an illustrative architecture diagram of the real-time navigation system. Second, we focus on data preprocessing, where a cross-correlation approach is proposed to tackle multi-sensor time synchronization issues, specifically to determine potential time lags in IMU data. The final phase covers the fusion of multi-sensor data and motion constraints. The Extended Kalman Filter (EKF) forms the backbone of this part, with Zero Velocity Update (ZUPT) and Non-Holonomic Constraints (NHC) being integrated into the Loosely Coupled (LC) scheme. Furthermore, the IMU calibration process is performed to ascertain necessary algorithmic parameters. Experimental results, conducted in diverse environments (open sky, GNSS challenging, and GNSS denied), will be presented in this paper. Comparisons with reference data indicate that the navigation accuracy of the developed integrated system, both in terms of hardware and navigation algorithm, achieves expected meter-level accuracy, fulfilling the "Which Lane" and "Which Road" level criteria in varied environments. Furthermore, outcomes from the GNSS denied environment align with predictions based on propagation error theory, demonstrating the feasibility of our navigation algorithm for tactical integrated navigation systems.

Wear characteristics analysis of variable hyperbolic circular-arc-tooth-trace cylindrical gear transmission considering assembly error theory

Wear is the main failure form of the gear transmission interface, runs through the whole life cycle of gear service, and the distributed error of the tooth surface due to the introduced assembly error will make the actual meshing state of the tooth surface different from the ideal meshing state, thus affecting the tooth surface wear trajectory and state. Therefore, considering the coupling relationship between assembly error and tooth surface contact analysis, the variation laws of the wear amount of the gear transmission interface of the variable hyperbolic circular-arc-tooth-trace cylindrical gear were studied under the consideration of assembly error in this article. Based on the tooth surface contact analysis method and Hertz contact theory, the transient linear load, the combined radius of curvature, the length axis and short axis of the contact ellipse, and the instantaneous sliding velocity were calculated. Through revising the calculation method of adhesive wear of variable hyperbolic circular-arc-tooth-trace cylindrical gears, the correlations between the tooth surface wear amount and gear parameters of variable hyperbolic circular-arc-tooth-trace cylindrical gears under different assembly errors were analyzed. The results show that the maximum wear occurs at the root of the tooth, and the wear at the indexing circle approaches zero, whether it is standard installation or non-standard installation. The vertical axial error and horizontal axial error have little effect on the wear, while the center distance error will aggravate the wear. The proposed method comprehensively considers the influence of assembly error and gear parameters on tooth surface wear, and this method can provide a theoretical reference for the design and analysis of anti-wear, wear reduction, and life extension of variable hyperbolic circular-arc-tooth-trace cylindrical gear tooth surface.

Minimalism's continued creep: Subject matter

AbstractThe problem of creeping minimalism is the problem of drawing a principled distinction between expressivists and non‐expressivists. Explanationism is a popular strategy for solving the problem, but two of its forms—ontological explanationism and representational explanationism—have fatal problems. Christine Tiefensee and Matthew Simpson have recently, and independently, endorsed a third form: subject matter explanationism. But this form also fails. At bottom, the problem is that it does not note the existence of non‐reductive expressivist views, just as earlier forms of explanationism did not note the existence of error theories, or non‐naturalist realists, or realists who wanted to endorse deflationary views of truth and representation. The failure of this latest version of explanationism—one that does indeed avoid problems with earlier versions—strengthens the case that we may not actually want a solution to the problem of creeping minimalism after all. Rather, a form of global expressivism—neopragmatism—might be regarded as yielding a version of non‐naturalist normative realism.

Paternalism Is Not Less Wrong in Intimate Relationships

Abstract Many believe that paternalism is less wrong in intimate relationships. In this paper, we argue that this view cannot be justified by appeal to (i) beneficence, (ii) shared projects, (iii) vulnerability, (iv) epistemic access, (v) expressivism, or (vi) autonomy as nonalienation. We finally provide an error theory for why many may have believed that paternalism is less wrong in intimate relations.

Explicit pipe friction factor equations: evaluation, classification, and proposal

The Colebrook equation has been used to estimate the friction factor (f) in turbulent fluids. In this regard, many equations have been proposed to eliminate the iterative process of the Colebrook equation. The goal of this article was to perform an evaluation, classification, and proposal of the friction factor for better development of hydraulic projects. In this study, Gene Expression Programming (GEP), Newton-Raphson, and Python algorithms were applied. The accuracy and model selection were performed with the Maximum Relative Error (∆f/f), Percentage Standard Deviation (PSD), Model Selection Criterion (MSC), and Akaike Information Criterion (AIC). Of the 30 equations evaluated, the Vatankhah equation was the most accurate and simplest to obtain the friction factor with a classification of very high, reaching a value of ∆f/f<0.5% and 1.5<PSD<1.6. A new equation was formulated to obtain the explicit f with fast convergence and accuracy. It was concluded that the combination of GEP, error theory, and selection criteria provides a more reliable and strengthened model.

Error theory study on EKF-based SOC and effective error estimation strategy for Li-ion batteries

Accurate state-of-charge (SOC) estimation is crucial for ensuring the safe and reliable operation of battery management systems (BMS). Among the various algorithms used for SOC estimation in real-vehicle BMS, the extended Kalman filter (EKF) algorithm holds significance due to its adherence to optimal estimation principles and its property of insensitivity to initial values. By studying the relationship between error sources and SOC estimation errors, it becomes possible to develop targeted measures for enhancing the accuracy of SOC estimation based on the EKF. From a probabilistic perspective, this paper derives theoretical equations that establish the connection between SOC estimation errors and various error sources, including measured voltage, measured current, open circuit voltage curve, capacity, ohmic internal resistance, and polarization resistance. Furthermore, the paper analyzes the relationship among multiple error sources in generating SOC estimation errors. Building upon the outcomes of this theoretical analysis, a joint SOC estimation method that combines the EKF with Ampere-hour counting (AHC) is employed to identify errors. In scenarios where simultaneous faults occur in the current and voltage sensors, they are identified based on the slope and Euclidean distance of the two SOC trajectories, respectively. Subsequently, sensor faults correction and SOC compensation are implemented by leveraging simplified equations involving capacity and SOC increments and measured voltage and SOC estimation errors. In addition to addressing sensor faults, the paper also considers battery model parameter errors. By incorporating customized current pulse profile and theoretical equations relating to error sources and SOC estimation errors, a comprehensive error estimation of model parameters is achieved, capable of handling single and multiple errors. The derived simplification bridges the gap between error sources and SOC estimation errors, offering a novel approach for parameter sensitivity analysis and a theoretical foundation for quantifying these errors. The experimental results demonstrate the effectiveness and rapidity of the proposed method for identifying and correcting sensor faults and model parameter errors.

True and error analysis instead of test of correlated proportions: Can we save lexicographic semiorder models with error theory?

This article criticizes conclusions drawn from the standard test of correlated proportions when the dependent measure contains error. It presents a tutorial on a new method of analysis based on the true and error (TE) theory. This method allows the investigator to separate measurement of error from substantive conclusions about the effects of the independent variable, but it requires replicated measures of the dependent variable. The method is illustrated with hypothetical examples and with empirical data from tests of lexicographic semiorder (LS) models proposed as descriptive theories of risky decision making. LS models imply a property known as interactive independence. Data from two previous studies are reanalyzed to test interactive independence. The new analyses yielded clear answers: interactive independence can be rejected; therefore, LSs can be rejected as descriptive, even when the most flexible error model is allowed. The new methods of analysis can be applied to situations in which the test of correlated proportions would be applied, where it is possible to obtain repeated measures.

Moralnost bez kategoričnosti

This paper argues that an agent’s moral obligations are necessarily connected to her desires. In doing so I will demonstrate that such a view is less revisionary—and more in line with our common-sense views on morality—than philosophers have previously taken it to be. You can hold a desire-based view of moral normativity, I argue, without being (e.g.) a moral relativist or error theorist about morality. I’ll make this argument by showing how two important features of an objective morality are compatible with such a desire-based account: 1) morality’s authoritative nature, 2) our ability to condemn immoral agents.

Design method for relief well trajectory to avoid side-track operations and control the relative distance

A blowout can cause significant damage to both property and the environment. The relief well is the final and most helpful option to intercept and stop the blowout. However, the relief well trajectory design methods are still closely guarded by oil companies. Compared with conventional directional wells, additional design parameters such as relative azimuth and relative distance need to be considered in the relief well trajectory design. Therefore, designing the relief well trajectory with conventional methods is challenging. Moreover, side-track operations occur frequently in relief well engineering. Quantifying and reducing side-tracking risk is also an urgent problem to be solved. A new relief well trajectory profile is established based on the dual-2D well trajectory to address these challenges. The design parameters are determined in this profile. Then, a side-tracking risk calculation model is developed based on the well trajectory control theory and error theory. To minimize the side-tracking risk, a design parameter optimization method is established. The relief well “pass-by” trajectory is designed with this new design method. The result shows that, with this optimization method, the relative distances and relative azimuths can be determined in the following and intercepting phases. The relative distances between the relief well and target well are verified. The result shows that the new relief well trajectory can meet the requirements of relative distance. The traditional design method and the new design method are compared. The result shows that the new design method can effectively avoid complicated trial calculations and control the relative distance. In this paper, an effective design method for the relief well trajectory is established. The optimization objective of side-tracking risk is introduced into the relief well trajectory design method, which provides a new way for design parameter optimization. The relief well trajectory design method with a directional target well and new optimization objectives should be paid attention to in further research.

Do formal objections to the error theory overgeneralize?

Abstract We argued that formal objections to the error theory overgeneralize and therefore fail. Christine Tiefensee and Gregory Wheeler deny this. We argue that they are wrong, for two reasons. The first concerns how we should adjudicate conflicts between formal and substantive commitments. The second concerns an overlooked tension between formal objections and non-error-theoretic views. Our discussion shows that the commitments behind formal objections to the error theory, such as the dual schema, should be regarded as much more contentious than is often assumed.
