    Application of Supply-Demand-Based Optimization for Parameter Extraction of Solar Photovoltaic Models.Guojiang Xiong, Jing Zhang, Dongyuan Shi & Xufeng Yuan - 2019 - Complexity 2019:1-22.
    Modeling solar photovoltaic systems accurately is based on optimal values of unknown model parameters of PV cells and modules. In recent years, the use of metaheuristics for parameter extraction of PV models gains more and more attentions thanks to their efficacy in solving highly nonlinear multimodal optimization problems. This work addresses a novel application of supply-demand-based optimization to extract accurate and reliable parameters for PV models. SDO is a very young and efficient metaheuristic inspired by the supply and (...)

    Data Trimming, Nuclear Emissions, and Climate Change.Kristin Sharon Shrader-Frechette - 2009 - Science and Engineering Ethics 15 (1):19-23.
    Ethics requires good science. Many scientists, government leaders, and industry representatives support tripling of global-nuclear-energy capacity on the grounds that nuclear fission is “carbon free” and “releases no greenhouse gases.” However, such claims are scientifically questionable (and thus likely to lead to ethically questionable energy choices) for at least 3 reasons. (i) They rely on trimming the data on nuclear greenhouse-gas emissions (GHGE), perhaps in part because flawed Kyoto Protocol conventions require no full nuclear-fuel-cycle assessment of carbon content. (ii) They (...)

    Climate Change, Nuclear Economics, and Conflicts of Interest.Kristin Shrader-Frechette - 2011 - Science and Engineering Ethics 17 (1):75-107.
    Merck suppressed data on harmful effects of its drug Vioxx, and Guidant suppressed data on electrical flaws in one of its heart-defibrillator models. Both cases reveal how financial conflicts of interest can skew biomedical research. Such conflicts also occur in electric-utility-related research. Attempting to show that increased atomic energy can help address climate change, some industry advocates claim nuclear power is an inexpensive way to generate low-carbon electricity. Surveying 30 recent nuclear analyses, this paper shows that industry-funded studies appear to (...)

    Influences of Technological Attributes and Environmental Factors on Technology Commercialization.Chih-Jou Chen, Chia-Chin Chang & Shiu-Wan Hung - 2011 - Journal of Business Ethics 104 (4):525-535.
    As part of a new focus on sustainability, this study examines the effects of technological attributes, market potential, and environmental factors on the commercialization of technologies. A survey was conducted on two of Taiwan’s promising sustainable high-tech industries—solar photovoltaic (PV) and light emitting diodes (LEDs). We found that if the technologies possess the specific attributes of innovativeness, genericness, simplicity, and compatibility, as required by the potential adopters, the level of market potential will be more favorable and technology commercialization (...)

    El ready made y la ruptura de la noción de arte del Modernismo.Jaime Aranda del Solar - 2009 - Estudios de Filosofía: Revista del Seminaro de Filosofia del instituto Riva-Aguero 7:27-43.
    Este artículo revisa el modo en que la aparición de objetos críticos, como el Portabotellas de Duchamp, hacen entrar en crisis las nociones tradicionalmente aceptadas respecto de la obra de arte: su manualidad (la “buena factura”, producto de la destreza o habilidad del artista), su función representativa (mímesis) y su valor estético (el ser “bello”, objeto de una contemplación pura y desinteresada). Se plantea, así, que la aparición del ready made configura el momento final de un proceso de disolución de (...)

    The Role of Deployment Policies in Fostering Innovation for Clean Energy Technologies.Joern Hoppmann - 2015 - Business and Society 54 (4):540-558.
    In recent years, governments in a large number of countries have introduced so-called deployment policies to foster the diffusion of clean energy technologies. While there is little doubt that these demand-side measures have been very effective in raising the share of clean electricity generation, currently, much less is known about how deployment policies affect—and are affected by—technological innovation beyond the mere diffusion of existing technologies. Against this backdrop, this dissertation abstract and commentary presents the dissertation work of Dr. Joern Hoppmann. (...)

  20. Ethical and Technical Challenges in Compensating for Harm Due to Solar Radiation Management Geoengineering.Toby Svoboda & Peter Irvine - 2014 - Ethics, Policy and Environment 17 (2):157-174.
    As a response to climate change, geoengineering with solar radiation management has the potential to result in unjust harm. Potentially, this injustice could be ameliorated by providing compensation to victims of SRM. However, establishing a just SRM compensation system faces severe challenges. First, there is scientific uncertainty in detecting particular harmful impacts and causally attributing them to SRM. Second, there is ethical uncertainty regarding what principles should be used to determine responsibility and eligibility for compensation, as well as determining (...)

    Starting a Flood to Stop a Fire? Some Moral Constraints on Solar Radiation Management.David R. Morrow - 2014 - Ethics, Policy and Environment 17 (2):123-138.
    Solar radiation management (SRM), a form of climate engineering, would offset the effects of increased greenhouse gas concentrations by reducing the amount of sunlight absorbed by the Earth. To encourage support for SRM research, advocates argue that SRM may someday be needed to reduce the risks from climate change. This paper examines the implications of two moral constraints?the Doctrine of Doing and Allowing, and the Doctrine of Double Effect?on this argument for SRM and SRM research. The Doctrine of Doing (...)

Burns & Andrew Strauss (eds.), Climate Change Geoengineering: Philosophical Perspectives, Legal Issues, and Governance Frameworks. Cambridge University Press.
    Some types of solar radiation management (SRM) research are ethically problematic because they expose persons, animals, and ecosystems to significant risks. In our earlier work, we argued for ethical norms for SRM research based on norms for biomedical research. Biomedical researchers may not conduct research on persons without their consent, but universal consent is impractical for SRM research. We argue that instead of requiring universal consent, ethical norms for SRM research require only political legitimacy in decision-making about global SRM (...)

    Astronomers of the first half of the nineteenth century viewed our solar system entirely differently from the way twentieth-century astronomers viewed it. In the earlier period the dominant image was of a set of planets and moons, both of which kinds of bodies were inhabited by intelligent beings comparable to humans. By the early twentieth century, science had driven these beings from every planet in our system except the Earth, leaving our solar system as more or less desolate (...)

    Abstract Environmental and public health-focused sciences are increasingly characterised as constituting an emerging discipline—planetary medicine. From a governance perspective, the ethical components of that discipline may usefully be viewed as bestowing upon our ailing natural environment the symbolic moral status of a patient. Such components emphasise, for example, the origins and content of professional and social virtues and related ethical principles needed to promote global governance systems and policies that reduce ecological stresses and pathologies derived from human overpopulation, selfishness and (...)

    Solar radiation management is a form of geoengineering that involves the intentional manipulation of solar radiation with the aim of reducing global average temperature. This paper explores what precaution implies about the status of solar radiation management. It is argued that any form of solar radiation management that poses threats of catastrophe cannot constitute an appropriate precautionary measure against another threat of catastrophe, namely climate change. Research of solar radiation management is appropriate on a precautionary (...)

    This important edited collection addresses ethical issues associated with solar radiation management (SRM), a category of climate engineering techniques that would increase the planet’s reflectivity in order to offset some of the impacts of anthropogenic climate change. Such techniques include injecting sulfate aerosols into the stratosphere or brightening marine clouds with seawater. Although SRM has the potential to cool the planet by reducing the amount of incoming solar radiation absorbed by the planet, it raises a wide array of (...)

    Toward Legitimate Governance of Solar Geoengineering Research: A Role for Sub-State Actors.Sikina Jinnah, Simon Nicholson & Jane Flegal - 2019 - Ethics, Policy and Environment 21 (3):362-381.
    ABSTRACTTwo recently proposed solar radiation management experiments in the United States have highlighted the need for governance mechanisms to guide SRM research. This paper draws on the literatures on legitimacy in global governance, responsible innovation, and experimental governance to argue that public engagement is a necessary condition for any legitimate SRM governance regime. We then build on the orchestration literature to argue that, in the absence of federal leadership, U.S. states, such as California, New York, and other existing leaders (...)

    The Search on Mars for a Second Genesis of Life in the Solar System and the Need for Biologically Reversible Exploration.Christopher McKay - 2018 - Biological Theory 13 (2):103-110.
    The discovery of a second genesis of life besides the one on Earth, this time on Mars, would have profound scientific and philosophical implications. Scientifically, it would provide a second example of biochemistry and of evolutionary history. Many important biological questions may be answerable through the comparison of biochemistry between the life forms on the two planets. Philosophically, the discovery of a second genesis of life in our solar system would suggest that the phenomenon of life is distributed throughout (...)

    This paper discusses a series of case studies on observations, experiments, and the theoretical interpretation between 1890 and 1960 of a shift of dark Fraunhofer lines in the solar spectrum. I argue for the use of flow charts to analyze interconnections and to identify sequences of research strategies. Also I advocate using a newly-developed tool called "block diagram" representation of experimental systems as an appropriate method to identify recurrent patterns in the interplay of instrumentation, experiment, and theory in research (...)

    Undecidability in Rn: Riddled Basins, the KAM Tori, and the Stability of the Solar System.Matthew W. Parker - 2003 - Philosophy of Science 70 (2):359-382.
    Some have suggested that certain classical physical systems have undecidable long-term behavior, without specifying an appropriate notion of decidability over the reals. We introduce such a notion, decidability in (or d- ) for any measure , which is particularly appropriate for physics and in some ways more intuitive than Ko's (1991) recursive approximability (r.a.). For Lebesgue measure , d- implies r.a. Sets with positive -measure that are sufficiently "riddled" with holes are never d- but are often r.a. This explicates Sommerer (...)

Of them, the extensive observations of lunar eclipses available before 1000 AD for testing the ephemeredes computed from the astronomical tables are in a relatively sharp contrast to the twelve lunar observations that are pertained to the four extant accounts (...)

    Apart from hydrogen, helium is the most abundant chemical element in the universe, and yet it was only discovered on the Earth in 1895. Its early history is unique because it encompasses astronomy as well as chemistry, two sciences which the spectroscope brought into contact during the second half of the nineteenth century. In the modest form of a yellow spectral line known as D3, ‘helium’ was sometimes supposed to exist in the Sun's atmosphere, an idea which is traditionally ascribed (...)

    How Thales Was Able to "Predict" a Solar Eclipse Without the Help of Alleged Mesopotamian Wisdom.Dirk Couprie - 2004 - Early Science and Medicine 9 (4):321-337.
    The first part of this article examines Patricia O'Grady's recent attempt to identify the method by which Thales might have successfully predicted a solar eclipse. According to O'Grady, some 60% of the potentially visible lunar eclipses were followed 23½ months later by potentially visible solar eclipses. It is shown that this ratio is no more than 23%, and that the method fails to predict after which specific lunar eclipse a solar eclipse will appear. In the second half (...)

  44. "Solar Love": Nietzsche, Merleau-Ponty and the Fortunes of Perception. [REVIEW]Fred Evans - 1998 - Continental Philosophy Review 31 (2):171-193.
    Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each (...)

    The Trend of the Dansgaard-Oescher Cycle with Solar Activity.Victor Manuel Velazco Herrera & Oscar Sosa Flores - 2010 - Dialogue and Universalism 20 (11-12):77.
    The nature of the climatic response to solar variability is assessed over a long-time scale, as in the case of the periodicity of 1500 years (Dansgaard-Oeschger cycle). For this reason it is important to perform an analysis to detect the existence of this periodicity in the Holocene and the possible influence of the sun on this periodicity. For this purpose, the method of Wavelet analysis in time-frequency was used. The information of oxygen isotopes (δ18O) and Berilium-10 (10Be) at the (...)

    Another Look at Just-So Solar Neutrino Oscillations.James M. Gelb & S. P. Rosen - 2000 - Foundations of Physics 30 (4):599-606.
    We take another look at “Just-So” solar neutrino oscillations, characterizing them by the energy Eπ/2 at which the distance-varying angle is π/2, instead of by the usual Δm 2 . The rising spectrum recently observed by SuperKamiokande is consistent with an Eπ/2 ∼6–9 MeV and marginally with 48 MeV. The pp neutrinos must then be reduced to one-half the standard solar model prediction, and 7Be neutrinos must make up a significant part of the SAGE and GALLEX gallium signal. (...)

    Prelude to Solar Energy: Pouillet, Herschel, Forbes and the Solar Constant.Peggy Aldrich Kidwell - 1981 - Annals of Science 38 (4):457-476.
    Inspired by early-nineteenth-century discoveries about heat transfer, the French physicist Claude Pouillet measured the influx of solar radiation at the earth and, in 1838, asked what these observations revealed about the temperature of the sun and of space itself. At about the same time, the British natural philosophers John Herschel and J. D. Forbes made similar measurements in order to better understand the sun's influence on climate. This paper tells how and why Pouillet, Herschel and Forbes made the first (...)

    Economic and Social Foundations of Solar Energy.Bruce A. Mcdaniel - 1983 - Environmental Ethics 5 (2):155-168.
    Underlying solar energy development is a fundamental issue of values and individual choices. Where solar energy comes to include such ideas as appropriate decentralized technology, self-sufficiency and autonomy, and a responsibility to conserve and preserve the environment, solar energy can become a channel for exploring alternative values. The requirement here is to view solar energy not as just anotherenergy source maintaining an ever increasing fiow of consumption goods. Rather, solar energy should be viewed as an (...)

    Mayer, Herschel and Prévost on the Solar Motion.John Hendry - 1982 - Annals of Science 39 (1):61-75.
    It is traditionally held that Mayer denied the existence of a solar motion while Herschel and Prévost, using much the same data, demonstrated its presence. The existence of such diverse conclusions has not, however, been satisfactorily explained. It is shown here that the supposed disagreement as to the existence of a solar motion is illusory. Mayer did not make the denial attributed to him; and the estimates of Herschel and Prévost do not represent responses to the factual question (...)

    The Interplay Between Theory and Observation in the Solar Model of Hipparchus and Ptolemy.Kathleen Okruhlik - 1978 - PSA: Proceedings of the Biennial Meeting of the Philosophy of Science Association 1978:73 - 82.
    Attempts by twentieth-century historians to account for the successes and failures of the Hipparchian-Ptolemaic solar model provide valuable case studies for philosophers who are studying the relationship between observational data and theoretical constructs. A brief survey of recent literature on the solar model reveals that in some cases results which appear to be the product of highly accurate observation are, in fact, based on rather crude observations aided by a large measure of theoretical presupposition. On the other hand, (...)
