Quantum formalism for events and how time can emerge from its foundations

Although time is one of our most intuitive physical concepts, its understanding at the fundamental level is still an open question in physics. For instance, time in quantum mechanics and general relativity are two distinct and incompatible entities. While relativity deals with events (points in spacetime), with time being observer-dependent and dynamical, quantum mechanics describes physical systems by treating time as an independent parameter. To resolve this conflict, in this work, we extend the classical concept of an event to the quantum domain by defining an event as a transfer of information between physical systems. Then, by describing the universe from the perspective of a certain observer, we introduce quantum states of events with space-time-symmetric wave functions that predict the joint probability distribution of a measurement (observation) at $ (t, {\vec x}) $. Under these circumstances, we propose that a well-defined instant of time, like any other observable, arises from a single event, thus being an observer-dependent property. As a result, a counterfactual asymmetry along a particular sequence of events within a stationary quantum state gives rise to the flow of time as being successive "snapshots" from the observer's perspective. In this proposal, it is the many distinguishable states in which the observer stores information that makes the existence of time possible.

Explication as a Three-Step Procedure: the case of the Church-Turing Thesis

In recent years two different axiomatic characterizations of the intuitive concept of effective calculability have been proposed, one by Sieg and the other by Dershowitz and Gurevich. Analyzing them from the perspective of Carnapian explication, I argue that these two characterizations explicate the intuitive notion of effective calculability in two different ways. I will trace back these two ways to Turing’s and Kolmogorov’s informal analyses of the intuitive notion of calculability and to their respective outputs: the notion of computorability and the notion of algorithmability. I will then argue that, in order to adequately capture the conceptual differences between these two notions, the classical two-step picture of explication is not enough. I will present a more fine-grained three-step version of Carnapian explication, showing how with its help the difference between these two notions can be better understood and explained.

Hybrid Model Predictive Current and Voltage Control for LCL-Filtered Grid-Connected Inverter

The inductive-capacitive-inductive (LCL)-filtered grid-connected inverter features a high-order plant, complex parameter design, and vulnerability under disturbance factors. The transfer-function-based active damping (TFAD) scheme is commonly adopted to mitigate the resonance problem but with cascaded control loops and high design complexity. On the contrary, multiobjective optimization can be easily realized in model predictive control (MPC) via a predefined cost function. As the coupling dynamic among state variables, a hybrid cost function, which contains the grid current, inverter-side current, and capacitor voltage tracking, is designed to guarantee system stability. The optimized control law is generated according to the minimization of the designed cost function, which is further transformed into the driving pulse by the modulator stage. In this process, the weighting factors are exactly arranged to place the desired closed-loop poles. The control law can ensure zero error tracking of grid current reference, which is better than the state feedback way. The hybrid cost function with modified reference is also proposed to reject the harmonics caused by the unhealthy grid condition. The control delay is compensated by using the forecast reference and the predictive state variable estimated from the observer. The proposed scheme performs the intuitive concept, reduced tuning complexity, and fast dynamic response. Simulated results and experiments are presented to verify the proposed control strategy.

The use of paintings and sketches as scientific knowledge

ABSTRACT This article is written in the field of the philosophy of science. The aim is to express how painting and drawing can be used as part of a phenomenological research method. The painter or drawer is a visual researcher in the process of capturing a holistic and truthful experience of a cultural phenomenon. We will highlight the visual researcher process and how the experience of truth is known throughout this process. The paining and sketches, which we present in this article, are part of a book, together with written narratives and pedagogical theory – on teaching as a phenomenon – called Lærerpraksis og Pedagogisk teori. The paintings and drawings present teaching in a way that complements and expands the written text. The sketches and painting of teaching attempt to establish the truth as unconcealment of a phenomenon. Our argumentation is based on the theories of Gadamer, Cassirer, Panofsky and Heidegger. Gadamer connects humanistic research with artistry and the experience of truth. Cassirer argues that the perception of a cultural phenomenon begins as a holistic understanding to bring forth the symbolic form or essence of the phenomenon. Panofsky transfers the theory of Cassirer into the field of painting. The concept of synthetic intuition is the intrinsic knowing of a painting, which corresponds to Cassirer’s concept of symbolic forms. Heidegger’s theory explores how art unfolds and preserves the truth. We will argue that the connection between art and truth could bring forth important perspectives on phenomenological science and turn the research activity closer to an artistic form.

Optimizing the Believers: Six Additional Beliefs and Five Practices

This paper proposed a model of Islamic beliefs that not only aid in the development and innovation, but also make an individual goal-oriented, and efficient in their worldly chores. This supplementary or additional belief system is based on 1. Living Compassionately, 2. Understanding the natural laws, 3. Pursuance of Goals, 4. Knowing your personality and capabilities for Goals, 5. sharia-based moral Anchoring, 6. and avoiding pleasure-seeking. The modern concept of struggle (or Jihad) was also highlighted, and how this new struggle should be fought. Moreover, a set of practices were also proposed, that can make it easier to follow the belief system. These practices emphasized establishing a direct connection with Allah, the concept of perfection, learning, intuition, and inclusiveness. Furthermore, a historic analysis was also performed, explaining how scientific development was achieved in the golden age of Islam, and the factors that led to its demise, especially the institutional and philosophical weakness. In the end, I explored how inter-faith harmony can be achieved through this belief system.

On the Rational Basis of Revelation in Rosenzweig’s <i>Star of Redemption</i>

The present study focuses on ‘revelation,’ one of the three constitutive concepts, and possibly the most central such concept, in Rosenzweig’s philosophy. As opposed to its ostensibly religious meaning, the article offers a view of the rational element enfolded within this concept in Rosenzweig’s Star of Redemption. By employing a textual exegesis based on a close reading of Rosenzweig’s language, the article seeks to show that Rosenzweig’s conception of revelation does not refer to an intuitive, Kabbalistic-mystical or esoteric concept. As a central pillar of Rosenzweig’s star-shaped method, revelation is the mediator between God’s love of people to a person’s love of others – which, in turn, is the basis for global redemption. The exposure of the rational-intellectual aspect of revelation thus advances the desired objective of Rosenzweig’s method, and accords with Rosenzweig’s own words when he suggested that neither does it make the claim to be a philosophy of religion – how could it do that when the word ‘religion’ does not occur in it at all! Rather, it is merely a system of philosophy. The study seeks to explore the dialectical thicket of descriptions and arguments in The Star of Redemption in order to expose the logical kernel of Rosenzweig’s philosophical method. Indeed, a close reading which isolates the mechanical concepts of Rosenzweig’s thought reveals The Star of Redemption’s philosophical motivation when Rosenzweig denudes the text from the complex of religious concepts that are the proverbial flesh that surrounds the proverbial bones of the system Rosenzweig attacks. Insofar as The Star of Redemption is concerned, we are not dealing with systematicism in the sense of a rigid consistency of rationality as a concept, but rather with a methodical outline where Rosenzweig describes religion’s sociological ‘skeleton’ and weaves his method around it using such concepts as “orientation” = “revelation” = “sharing” = “redemption.” Furthermore, the affinity between God and human passes through the affinity between one human and another. It therefore follows that the ‘warm welcome’ of revelation, is not a mystical experience, but rather a person’s conscious, rational, and reflexive orientation in her or his human environment.

Psychology in AI Stance

This review discusses the role of psychology in the development in the sector of artificial intelligence. Cognitive science bestows the scientific basis for advancement in the realm of artificial intelligence. Gleaning a high-tech machine that can think, learn, reason, experience, and can function autarchic bereft of supervision is one of the pivotal grails in all of computer science. Studies posit that higher education in psychology can smooth the path for reasoning about general issues. With a prodigiously autarchic, learning, reasoning, the artificially intelligent system comes with a need to possess hardware and software that transcribes processes and subsystems that subsist within a human brain including intuitive and emotional concepts. The idea of interweaving these two immense realms: the complexities of psychology and vitality of artificial intelligence has gained escalation in recent times. This review focuses on how computer implementation and psychological tools bring enhancement in the field of artificial intelligence.

Demystifying intuition as the main decision system used by farmers

Over the decades, many researchers have explored the concept of intuition as a decision-making process. However, most of this research does not quantify the important aspects of intuition, making it difficult to fully understand its nature and improve the intuitive process, enabling an efficient method of decision-making. The research described here, through a review of the relevant literature, demystifies intuition as a decision system by isolating the important intuition determining variables and relating them to quantitative intuition research. As most farm decisions are made through intuition, farmers, consultants, researchers and students of farm management will find the review useful, stimulating efforts for improving decision-making skills in farmers. The literature search covered all journals and recent decades and includes articles that consider the variables to be targeted in improving intuitive skill. This provides a basis for thinking about intuition and its improvement within the farming world. It was found from the literature that most of the logical areas that should influence decisions do in fact do so and should be targeted in improving intuition. One of the most important improvement processes is a farmer’s self-criticism skills through using a decision diary in conjunction with reflection and consultation leading to improved decisions. This must be in conjunction with understanding, and learning about, the many other variables also impacting on intuitive skill.

Theoretical study of the Cl(2P) + SiH4 reaction: global potential energy surface and product pair-correlated distributions. Comparison with experiment.

For the theoretical study of the title reaction, an analytical full-dimensional potential energy surface named PES-2021 was developed for the first time, by fitting high-level explicitly-correlated ab initio data. This reaction presented high exothermicity, (298 K) = -11.6 kcal mol-1, reproducing the experimental evidence; it is a barrierless reaction and no intermediate complexes were found. PES-2021 is a continuous and smooth potential energy surface, it includes intuitive concepts in its development and fitting, such as stretching and bending nuclear motions, and it presents analytical first energy derivatives. Based on PES-2021, kinetics and dynamics studies were carried out using quasi-classical trajectory calculations. In the kinetics study, over the temperature range 300-450 K, we observed that rate constants were practically independent of temperature, with an almost zero activation energy, as compared to 0.0 and -0.48 kcal mol-1 experimentally reported. In this kinetics study the role of the spin-orbit effect on reactivity was analysed. In the dynamics study, different product pair-correlated dynamics properties were compared with the only experimental evidence: product energy partition, product vibrational distribution, product angular distribution and product speed distribution. We observed two mechanisms of reaction, a stripping mechanism associated with large impact parameters and forward scattering, and an indirect mechanism associated with sideways-backward scattering related with "nearly-trapped" trajectories due to the product rotation. In general, theoretical results reasonably simulate the experimental measurements when they consider some rotational and vibrational constraints as well as binning techniques to mimic a quantum-mechanical behaviour. Although the agreement is not quantitative, the present results shed light on the mechanism of this difficult polyatomic reactive system.

Living on the Edge

Roman Stoicism is typically read as a therapeutic philosophy that is centered around the care of the self and presented in the form of a self-help manual. Closer examination reveals a less reassuring and more challenging side to the school’s teachings, one that provokes ethical reflection at the limits of the self’s intactness and coherence. The self is less an object of inquiry than the by-product of a complex set of experiences in the face of nature and society and across any number of flashpoints, from one’s own or others’ beliefs, actions, values, and relationships to the difficulty of sizing up one’s place in the universe. The pressures of natural and ethical reflection put intuitive conceptions of the self at considerable risk. The Roman Stoic self proves to be vulnerable, contingent, unbounded, relational, and opaque—in short, a rich matrix of problems that point beyond the individual self and anticipate contemporary critiques of the self.

OMNIVIL-An Autonomous Mobile Manipulator for Flexible Production.

Flexible production is a key element in modern industrial manufacturing. Autonomous mobile manipulators can be used to execute various tasks: from logistics, to pick and place, or handling. Therefore, autonomous robotic systems can even increase the flexibility of existing production environments. However, the application of robotic systems is challenging due to their complexity and safety concerns. This paper addresses the design and implementation of the autonomous mobile manipulator OMNIVIL. A holonomic kinematic design provides high maneuverability and the implemented sensor setup with the underlying localization strategies are robust against typical static and dynamic uncertainties in industrial environments. For a safe and efficient human–robot collaboration (HRC), a novel workspace monitoring system (WMS) is developed to detect human co-workers and other objects in the workspace. The multilayer sensor setup and the parallel data analyzing capability provide superior accuracy and reliability. An intuitive zone-based navigation concept is implemented, based on the workspace monitoring system. Preventive behaviors are predefined for a conflict-free interaction with human co-workers. A workspace analyzing tool is implemented for adaptive manipulation, which significantly simplifies the determination of suitable platform positions for a manipulation task.

Towards Higgs masses and decay widths satisfying the symmetries in the (N)MSSM

In models with an extended Higgs sector, such as the (N)MSSM, scalar states mix with one another. Yet, the concept of Higgs mixing is problematic at the radiative level, since it introduces both a scheme and a gauge dependence. In particular, the definition of Higgs masses and decay amplitudes can be impaired by the presence of gauge-violating pieces of higher order. We discuss in depth the origin and magnitude of such effects and consider two strategies that minimize the dependence on the gauge-fixing parameter and field-renormalization of one-loop order in the definition of the mass and decay observables, both in degenerate and non-degenerate scenarios. In addition, the intuitive concept of mixing and the simplicity of its definition in terms of two-point diagrams can make it tempting to include higher-order corrections on this side of the calculation, irrespectively of the order achieved in vertex diagrams. Using the global SU(2)_{mathrm{L}}-symmetry in the decoupling limit, we show that no improvement can be expected from such an approach at the level of the Higgs decays, but that, on the contrary, the higher-order terms may lead to numerically large spurious effects.

Evaluation of power supply capability and quality for traction power supply system considering the access of distributed generations

The access of distributed generations (DGs) in the traction power supply system (TPSS) can not only make use of the renewable energy near the railway route, but also improve the condition of weak external power supply. In order to quantify the effect when DGs access TPSS, this study proposes a method for evaluating the power supply capability and quality of TPSS which considers the access of DGs. First, the method fully considers the randomness and uncertainty of the power provided by DGs and that consumed by electrical locomotives. A comprehensive model of TPSS with the access of DGs is built by means of the stochastic model, and then the index system for evaluating the power supply capability and quality of TPSS is formulated. Finally, the Monte Carlo simulation is applied to calculate the probabilistic load flow to obtain the evaluation indices. The proposed method is verified by simulating a typical TPSS in a remote mountain area. The results show that the method can quantify the power supply capability and quality of the system after the access of DGs. It can provide an intuitive conception of the power supply condition for design and operation personnel.

Inhomogeneous interval fields based on scaled inverse distance weighting interpolation

This paper introduces a novel method to model non-deterministic quantities based on experimental measurement data. The focus of this work is on quantities that vary over a continuous domain, e.g., material properties, time-dependent strain rate effects, or stress–strain curves. These quantities are modelled by means of the recently introduced concept of interval fields. An interval field defines intervals that are defined throughout the continuous domain and have dependence in this domain by expanding them over a set of basis functions, describing the spatial nature of the non-determinism of the modelled quantities. One of the more intuitive concepts of defining basis functions in an interval field is through inverse distance weighting interpolation (IDW), which starts from known intervals at specific control points within the domain. For each of these control points, a corresponding basis function is defined, the relative weight of which is decreasing inversely with the distance. Through this definition, all intervals have non-vanishing basis functions throughout the model domain. This makes the application of standard IDW extremely challenging when the interval uncertainty varies inhomogeneously over the domain, i.e., when local effects are present in the model.Therefore, in this paper standard IDW is adapted by changing the distance measure. More specifically, the weight of intervals is increased locally, while diminishing the weight in other regions. For this purpose, a function is introduced that maps the domain to a higher dimension feature space, in which the distances that determine the weight are measured. This mapping function is based on either the size of the intervals at the control points or experimental data, which both yield additional control resulting in increased agreement with experimental data.This paper demonstrates that this method outperforms standard IDW in controllability, while limiting the number of control points. This is illustrated in three case studies: a first case concerning modelling local non-determinism; a second case where a mix of global and local effects is modelled; and the third case, where the interval field is based on experimental stress strain curves. In all these cases, multiple configurations demonstrate the effects of the parameters, and how the new technique is applied. The proposed technique outperforms standard IDW in all three case studies, with an increased coefficient of determination, R2, between 22% and 56%, in comparison to standard IDW.

Herd Agency

Abstract In this article, we draw upon ethnographic fieldwork conducted in Mongolia and China to develop understandings of herd–herder (mal–malchin) relations further. We focus primarily on horse-herding practices and related divisions of labour, and the three concepts of herd intuition (zön), serenity (taa) and fortune (buyan, khishig, zaya), to present additional interpretations of human–animal relations in Mongolia. Through this exploration, we develop the concept of herd agency and examine how it relates to specific horse-herding knowledge and techniques, as well as the cosmological significance of human–animal relations. All three concepts reveal the importance of cosmological agents with herd–herder relations. We conclude by emphasising the changing nature and politics of human–animal relations in these regions.

Counterfactual Knowledge, Factivity, and the Overgeneration of Knowledge

Antirealists who hold the knowability thesis, namely that all truths are knowable, have been put on the defensive by the Church–Fitch paradox of knowability. Rejecting the non-factivity of the concept of knowability used in that paradox, Edgington has adopted a factive notion of knowability, according to which only actual truths are knowable. She has used this new notion to reformulate the knowability thesis. The result has been argued to be immune against the Church–Fitch paradox, but it has encountered several other triviality objections. Schloder in a forthcoming paper defends the general approach taken by Edgington, but amends it to save it in turn from the triviality objections. In this paper I will argue, first, that Schloder’s justification for the factivity of his version of the concept of knowability is vulnerable to criticism, but I will also offer an improved justification that is in the same spirit as his. To the extent that some philosophers are right about our intuitive concept of knowability being a factive one, it is important to explore factive concepts of knowability that are made formally precise. I will subsequently argue that Schloder’s version of the knowability thesis overgenerates knowledge or, in other words, it leads to attributions of knowledge where there is ignorance. This fits a general pattern for the research programme initiated by Edgington. This paper also contains preliminary investigations into the internal and logical structure of lines of inquiries, which raise interesting research questions.

교수학적 상황론에 따른 직관적 확률 개념 지도

The purpose of this study is to search a possibility of desirable didactical situations for intuitive probability by designing and applying its mathematics lesson based on Brousseau’s theory of didactial situations(TDS). Based on my critical analysis on the didactical situations suggested by some precedent studies, I tried to design a didactical situation which makes the most of the intention of TDS through referring Brousseau’s lesson case so-called ‘the course to 20’. To do this, one-to-one game, team game, sharing strategies, and teacher’s intervention were designed respectively as situation of action, situation of formulation, situation of validation, and situation of institutionalization using Roller Derby game. I applied these situations to 18 fifth grade students and recognized their intuitive conceptions and misconceptions of probability by analyzing their game boards, their spoken words and discussion, and their discovered strategies through four phased situations. Furthermore, several didactical implications were induced for designing mathematics lessons based on TDS.

Spite and the Geometry of Negative Relatedness.

AbstractSpite is the most surprising prediction of inclusive fitness theory because it suggests that a gene can be favored by natural selection despite causing harm to both the individuals that carry it and those around them. A gene for spite can only be favored because of negative relatedness, which means that the actor that carries the gene is less likely to share the gene for spite with the surrounding recipients than the random expectation. While positive relatedness can be simply reduced to the intuitive concept of kinship, negative relatedness is deeply counterintuitive. Here I clarify that negative relatedness is frequency dependent, and I identify a hidden assumption in its widely used formula. Accordingly, while the well-studied "lighter" side of inclusive fitness (with helping behaviors and positive relatedness) is dominated by traits that are favored under kin selection, I predict that the understudied "darker" side of inclusive fitness (with harming behaviors and negative relatedness) is dominated by traits that are favored under greenbeard/kind selection-and I discuss the existing evidence that tentatively supports this hypothesis.

Implicit and Explicit Examples of the Phenomenon of Deviant Encodings

Abstract The core of the problem discussed in this paper is the following: the Church-Turing Thesis states that Turing Machines formally explicate the intuitive concept of computability. The description of Turing Machines requires description of the notation used for the input and for the output. Providing a general definition of notations acceptable in the process of computations causes problems. This is because a notation, or an encoding suitable for a computation, has to be computable. Yet, using the concept of computation, in a definition of a notation, which will be further used in a definition of the concept of computation yields an obvious vicious circle. The circularity of this definition causes trouble in distinguishing on the theoretical level, what is an acceptable notation from what is not an acceptable notation, or as it is usually referred to in the literature, “deviant encodings”. Deviant encodings appear explicitly in discussions about what is an adequate or correct conceptual analysis of the concept of computation. In this paper, I focus on philosophical examples where the phenomenon appears implicitly, in a “disguised” version. In particular, I present its use in the analysis of the concept of natural number. I also point at additional phenomena related to deviant encodings: conceptual fixed points and apparent “computability” of uncomputable functions. In parallel, I develop the idea that Carnapian explications provide a much more adequate framework for understanding the concept of computation, than the classical philosophical analysis.

IMOVE-An Intuitive Concept Mobility Systems for Perioperative Transfer and Induction of Anaesthesia for Special Needs Children.

Children with autistic spectrum disorder (ASD) often exhibit uncontrollable disruptive behaviour during transfer to the operating room and operating table and at the induction of anaesthesia (sleep). This process often involves the physical restraining of children. These children are then lifted onto the operating table by healthcare staff after being anaesthetized. This predisposes children to fall risk and hospital staff to musculoskeletal injuries. We developed two concept mobility devices, IMOVE-I and -II, based on robotics systems comprising of restraint modules and multi-positional modality (sitting, supine, Trendelenburg). The aim was to intuitively secure children to facilitate the safe induction of sleep and ease of transfer onto operating tables upon sleep. IMOVE-I loads the child in standing position using a dual arm restraint module that is activated by trained healthcare staff. IMOVE-II loads the child in the sitting position by motivating the self-application of restraints. Opinions were obtained from 21 operating theatre healthcare staff with experience in the care of ASD children and parents with ASD children. The mean satisfaction rating of IMOVE-I was 5.62 (95% CI 5.00, 6.27) versus 8.10 (95% CI 7.64, 8.55) in IMOVE-II, p < 0.001. IMOVE-II is favoured over IMOVE-I in system operation and safety, ease of use and module functionality.
