  1. Is Fourier Analysis Conservative over Physical Theory?Nicholas Danne - forthcoming - Logique Et Analyse.
    Hartry Field argues that conservative rather than true mathematical sentences facilitate deductions in nominalist (i.e., abstracta-free) science without prejudging its empirical outcomes. In this paper, I identify one branch of mathematics as nonconservative, for its indispensable role in enabling nominalist language about a fundamental scientific property, in a fictional scientific community. The fundamental property is electromagnetic reflectance, and the mathematics is Fourier analysis, which renders reflectance ascribable, and nominalist reflectance claims utterable, by this community. Using a recent characterization of (...)

  2. In search of space: Fourier spectroscopy, 1950-1970.Sean F. Johnston - 2001 - In B. Joerges & T. Shinn (eds.), Instrumentation: Between Science, State and Industry, Sociology of the Sciences Yearbook. Springer. pp. 121-141.
    In the large grey area between science and technology, specialisms emerge with associated specialists. But some specialisms remain ‘peripheral sciences’, never attaining the status of disciplines ensconced in universities, and their specialists do not become recognised professionals. A major social component of such side-lined sciences – one important grouping of techno-scientific workers – is the research-technology community. An important question concerning research-technology is to explain how the grouping survives without specialised disciplinary and professional affiliations. The case discussed illustrates the dynamics (...)

  3. Cultural Identity and Intergroup Conflicts: Testing Parochial Altruism Model via Archaeological Data.Hisashi Nakao - 2023 - Annals of the Japan Association for Philosophy of Science 32:75-87.
    The present research used archaeological data, i.e., the data obtained from kamekan jar burials in the Mikuni Hills of the northern Kyushu area in the Mid- dle Yayoi period, to test the parochial altruism model. This model argued that out-group hate and in-group favor coevolved via prehistoric intergroup conflicts. If this model is accurate, such an out-group hate and in-group favor could be re- flected in the archaeological remains, such as pottery making; the more frequent intergroup conflicts are and the (...)

  4. How to make reflectance a surface property.Nicholas Danne - 2020 - Studies in History and Philosophy of Science Part B: Studies in History and Philosophy of Modern Physics 70:19-27.
    Reflectance physicalists define reflectance as the intrinsic disposition of a surface to reflect finite-duration light pulses at a given efficiency per wavelength. I criticize the received view of dispositional reflectance (David R. Hilbert’s) for failing to account for what I call “harmonic dispersion,” the inverse relationship of a light pulse's duration to its bandwidth. I argue that harmonic dispersion renders reflectance defined in terms of light pulses an extrinsic disposition. Reflectance defined as the per-wavelength efficiency to reflect the superimposed, infinite-duration, (...)

  5. An Extra-Mathematical Program Explanation of Color Experience.Nicholas Danne - 2020 - International Studies in the Philosophy of Science 33 (3):153-173.
    In the debate over whether mathematical facts, properties, or entities explain physical events (in what philosophers call “extra-mathematical” explanations), Aidan Lyon’s (2012) affirmative answer stands out for its employment of the program explanation (PE) methodology of Frank Jackson and Philip Pettit (1990). Juha Saatsi (2012; 2016) objects, however, that Lyon’s examples from the indispensabilist literature are (i) unsuitable for PE, (ii) nominalizable into non-mathematical terms, and (iii) mysterious about the explanatory relation alleged to obtain between the PE’s mathematical explanantia and (...)

  6. Frequencies Dominations for Different Rating of Distribution Transformer under Transients.Haseeb Faisal, Dr Kashif Imdad, Najeeb Hussain & Faisal Sharif - 2020 - International Journal of Engineering Works 7 (04):211-216.
    Power transients faults on high voltage lines are prominently due to high frequency transients. These transients affect the predicted life and efficiency of equipment. The Fast Fourier Transform (FFT) is helpful in analysing the effect of high frequencies and Frequency Response Analysis (FRA) provide support in diagnosis and detection of deformation in a transformers. The major aim of this study is to analyse the incorporation of frequencies based on resonating core of a particular transformer. Using transfer function method an (...)

  7. Logic, mathematics, physics: from a loose thread to the close link: Or what gravity is for both logic and mathematics rather than only for physics.Vasil Penchev - 2023 - Astrophysics, Cosmology and Gravitation Ejournal 2 (52):1-82.
    Gravitation is interpreted to be an “ontomathematical” force or interaction rather than an only physical one. That approach restores Newton’s original design of universal gravitation in the framework of “The Mathematical Principles of Natural Philosophy”, which allows for Einstein’s special and general relativity to be also reinterpreted ontomathematically. The entanglement theory of quantum gravitation is inherently involved also ontomathematically by virtue of the consideration of the qubit Hilbert space after entanglement as the Fourier counterpart of pseudo-Riemannian space. Gravitation can (...)

  8. Optimisation of mixed proportion for cement brick containing plastic waste using response surface methodology (RSM).Chuck Chuan Ng - 2022 - Innovative Infrastructure Solutions 7.
    Plastic waste is a significant environmental problem for almost all countries; therefore, protecting the environment from the problem is crucial. The most sensible solution to these problems is substituting the natural aggregates with substantial plastic waste in various building materials. This study aimed to optimise the mixed design ratio of cement brick containing plastic waste as aggregate replacement. Plastic cement brick mixtures were prepared by the incorporation of four different types of plastic waste such as polyethylene terephthalate (PET), high-density polyethylene, (...)

  9. Desde Robert Owen: contexto histórico y de pensamiento en la génesis del “socialismo utópico”.José Ramón Álvarez Layna & Pilar Centeno Galván - 2008 - A Parte Rei: Revista de Filosofía 55 (55):1-22.
    ABSTRACT: In this text, we are going to try to introduce a few brief notes - without excessive pretensions -, concerning those things that, from a historical and also from an intellectual and point of view, surround the figures of Robert Owen, Fourier or Saint Simon. Certainly, intellectually, our sources do not let us notice a very specific influence on the "utopian socialists" of the 19th Century. It will be very difficult to find historical evidence. However, what we can (...)

    ABSTRACT: In the present text, we are going to introduce a series of notes without excessive pretensions. In these pages, we will try to study figures like Cabet, Fourier or Saint - Simon, and we will do so in order to achieve better understanding concerning their own historical and their own intellectual context. Consequently and leaving our papers on Robert Owen behind, we plan to set special emphasis on the European Continent now. In a special way, we raise awareness (...)

  11. Una defensa de Robert Owen: para una nueva lectura del utopismo en la historia.José Ramón Álvarez Layna - 2007 - A Parte Rei: Revista de Filosofía 53 (53):1-76.
    ABSTRACT: In its historical deployment, socialist thought has attracted the attention of numerous experts and thinkers. The results reached from the above mentioned efforts, are quite irregular in fact. These studies are very often linked the marxist tradition, that shifted its identity to label previous social reformers as "utopian socialists". Specifically, our academic Spanish tradition has traditionally been dependant -historically and intellectually- on other Continental currents of thought. We state, that the preeminence and fundamental influence on our Spanish culture in (...)

  12. An unconvincing transformation? Michelson's interferential spectroscopy.Sean F. Johnston - 2003 - Nuncius 18 ( 2):803-823.
    Albert Abraham Michelson (1852-1931), the American optical physicist best known for his precise determination of the velocity of light and for his experiments concerning aether drift, is less often acknowledged as the creator of new spectroscopic instrumentation and new spectroscopies. He devised a new method of light analysis relying upon his favourite instrument – a particular configuration of optical interferometer – and published investigations of spectral line separation, Doppler-broadening and simple high-resolution spectra (1887-1898). Contemporaries did not pursue his method. Michelson (...)

  13. Active Techniques Implemented in an Introductory Signal Processing Course to Help Students Achieve Higher Levels of Learning.Saharnaz Baghdadchi, Rebecca Hardesty, Paul Andreas Hadjipieris & Jace Hargis - 2018 - Papers on Engineering Education Repository.
    Holding students to high standards and assessing, measuring and evaluating their learning with challenging, authentic problems in the midterm and final exams is the goal of the professors who teach core signal processing concepts. However, the heavy reliance of these subjects on mathematics makes it difficult for students to genuinely grasp the concepts and relate to a conceptual framework. Specifically, analyzing the signals and the functionality of systems in Fourier domain; separating the system level analysis from signal level analysis; (...)

    Given the hard problem of consciousness, there are no brain electrophysiological correlates of the subjective experience (the felt quality of redness or the redness of red, the experience of dark and light, the quality of depth in a visual field, the sound of a clarinet, the smell of mothball, bodily sensations from pains to orgasms, mental images that are conjured up internally, the felt quality of emotion, the experience of a stream of conscious thought, or the phenomenology of thought).

    In the light of the results obtained during the last two decades in analysis of signals by time series, it has become evident that the tools of non linear dynamics have their elective role of application in biological, and, in particular, in neuro-physiological and psycho-physiological studies. The basic concept in non linear analysis of experimental time series is that one of recurrence whose conceptual counterpart is represented from variedness and variability that are the foundations of complexity in dynamic processes. Thus, (...)

Os horrores reais de uns nos impedem de sonhar com os outros. Nossas antigas utopias De Platão a Thomas More, de Étienne Cabet a Fourier, as utopias falavam da rejeição do presente e do real: “Existe o mal na comunidade dos homens”.

    What could be more inert than mathematical objects? Nothing distinguishes them from rocks and yet, if we examine them in their historical perspective, they don't actually seem to be as lifeless as they do at first. Conceived as they are by humans, they offer a glimpse of the breath that brings them to life. Caught in the web of a language, they cannot extricate themselves from the form that the tensive forces constraining them have given them. While they do not (...)
