  3. A Proposed Knowledge Based System for Desktop PC Troubleshooting.Ahmed Wahib Dahouk & Samy S. Abu-Naser - 2018 - International Journal of Academic Pedagogical Research (IJAPR) 2 (6):1-8.
    Abstract: Background: In spite of the fact that computers continue to improve in speed and functions operation, they remain complex to use. Problems frequently happen, and it is hard to resolve or find solutions for them. This paper outlines the significance and feasibility of building a desktop PC problems diagnosis system. The system gathers problem symptoms from users’ desktops, rather than the user describes his/her problems to primary search engines. It automatically searches global databases of problem symptoms and solutions, and (...)

    Buildings energy consumption is growing gradually and put away around 40% of total energy use. Predicting heating and cooling loads of a building in the initial phase of the design to find out optimal solutions amongst different designs is very important, as ell as in the operating phase after the building has been finished for efficient energy. In this study, an artificial neural network model was designed and developed for predicting heating and cooling loads of a building based on a (...)

  5. The Promise of Happiness.Sara Ahmed - 2010 - Duke University Press.
    _The Promise of Happiness_ is a provocative cultural critique of the imperative to be happy. It asks what follows when we make our desires and even our own happiness conditional on the happiness of others: “I just want you to be happy”; “I’m happy if you’re happy.” Combining philosophy and feminist cultural studies, Sara Ahmed reveals the affective and moral work performed by the “happiness duty,” the expectation that we will be made happy by taking part in that which (...)

    The Role of Individual Variables, Organizational Variables and Moral Intensity Dimensions in Libyan Management Accountants’ Ethical Decision Making.Ahmed Musbah, Christopher J. Cowton & David Tyfa - 2016 - Journal of Business Ethics 134 (3):335-358.
    This study investigates the association of a broad set of variables with the ethical decision making of management accountants in Libya. Adopting a cross-sectional methodology, a questionnaire including four different ethical scenarios was used to gather data from 229 participants. For each scenario, ethical decision making was examined in terms of the recognition, judgment and intention stages of Rest’s model. A significant relationship was found between ethical recognition and ethical judgment and also between ethical judgment and ethical intention, but ethical (...)

    Distinguishing Gas-Bearing Sandstone Reservoirs Within Mixed Siliciclastic-Carbonate Sequences Using Extended Elastic Impedance: Nile Delta — Egypt.Ahmed Hafez & John P. Castagna - 2016 - Interpretation: SEG 4 (4):T427-T441.
    In the Abu Madi Formation of the Nile Delta Basin, false bright spots may be misinterpreted as being indicative of hydrocarbons due to mixed clastics and carbonates. However, rock-physics analysis of well logs in a particular prospect area where such ambiguity exists suggests that attributes derived using extended elastic impedance inversion may help identify hydrocarbons because they better show anomalous behavior in particular directions that are readily related to pore fluids and lithology. The EEI attributes calculated from well logs correlate (...)

    What Does ‘Solidarity Economy’ Mean? Contours and Feasibility of a Theoretical and Political Project.Pepita Ould Ahmed - 2015 - Business Ethics: A European Review 24 (4):425-435.
    The market relationships are being contested. This can be seen in the increasing number of alternative social experiments in the ‘North’ and the ‘South’ which propose to think out the present market relationships in a different way, in particular in establishing exchange value and in facilitating access to trade. These practical alternatives are supported by trends in academic circles that over the past three decades have opposed neoliberal capitalism and individualism in today's commercialised society. Calling for greater solidarity and social (...)

    Evidence, Decision and Causality.Arif Ahmed - 2014 - Cambridge University Press.
    Most philosophers agree that causal knowledge is essential to decision-making: agents should choose from the available options those that probably cause the outcomes that they want. This book argues against this theory and in favour of evidential or Bayesian decision theory, which emphasises the symptomatic value of options over their causal role. It examines a variety of settings, including economic theory, quantum mechanics and philosophical thought-experiments, where causal knowledge seems to make a practical difference. The arguments make novel use of (...)

    Self-Sacrificial Leadership and Employee Behaviours: An Examination of the Role of Organizational Social Capital.Ahmed Mohammed Sayed Mostafa & Paul A. Bottomley - 2018 - Journal of Business Ethics 161 (3):641-652.
    Drawing on social exchange theory, this study examines a mechanism, namely organizational social capital, through which self-sacrificial leadership is related to two types of employee behaviours: organizational citizenship behaviours and counterproductive behaviours. The results of two different studies in Egypt showed that self-sacrificial leadership is positively related to OSC which, in turn, is positively related to OCBs and negatively related to CPBs. Overall, the findings suggest that self-sacrificial leaders are more likely to achieve desirable employee behaviours through improving the quality (...)

    Argumentation and Fallacy in the Justification of the 2003 War on Iraq.Ahmed Sahlane - 2012 - Argumentation 26 (4):459-488.
    The present study examined how the pre-war debate of the US decision to invade Iraq (in March 2003) was discursively constructed in the US/British mainstream newspaper opinion/editorial (op/ed) argumentation. Drawing on theoretical insights from critical discourse analysis and argumentation theory, I problematised the fallacious discussion used in the pro-war op/eds to build up a ‘moral/legal case’ for war on Iraq based on adversarial (rather than dialogical) argumentation. The proponents of war deployed ‘instrumental rationality’ (ends-justify-means reasoning), ‘ethical necessity’ (Bush’s ‘Preemption Doctrine’) (...)

    Martin's Axiom, Omitting Types, and Complete Representations in Algebraic Logic.Tarek Sayed Ahmed - 2002 - Studia Logica 72 (2):285-309.

We prove an independence result connecting cylindric algebra to Martin's axiom. Finally we apply our results to finite-variable first order logic showing that Henkin and Orey's omitting types theorem fails for $L_{n}$, the first order logic restricted to the first n variables when 2 < n < ω. $L_{n}$ has been recently studied as a many-dimensional modal (...)

    Willful Subjects.Sara Ahmed - 2014 - Duke University Press.
    In _Willful Subjects_ Sara Ahmed explores willfulness as a charge often made by some against others. One history of will is a history of attempts to eliminate willfulness from the will. Delving into philosophical and literary texts, Ahmed examines the relation between will and willfulness, ill will and good will, and the particular will and general will. Her reflections shed light on how will is embedded in a political and cultural landscape, how it is embodied, and how will (...)

  27. The Early Arabic Liar: The Liar Paradox in the Islamic World From the Mid-Ninth to the Mid-Thirteenth Centuries Ce.Ahmed Alwishah & David Sanson - 2009 - Vivarium (1):97-127.
    We describe the earliest occurrences of the Liar Paradox in the Arabic tradition. e early Mutakallimūn claim the Liar Sentence is both true and false; they also associate the Liar with problems concerning plural subjects, which is somewhat puzzling. Abharī (1200-1265) ascribes an unsatisfiable truth condition to the Liar Sentence—as he puts it, its being true is the conjunction of its being true and false—and so concludes that the sentence is not true. Tūsī (1201-1274) argues that self-referential sentences, like the (...)

    Deepwater Reservoir Heterogeneity Delineation Using Rock Physics and Extended Elastic Impedance Inversion: Nile Delta Case Study.Ahmed Hafez, Folkert Majoor & John P. Castagna - 2014 - Interpretation: SEG 2 (4):T205-T219.
    Deepwater channel reservoirs in the Nile Delta are delineated using extended elastic impedance inversion. We used the following workflow: seismic spectral blueing, rock physics and amplitude variation with offset modeling, seismic EEI and interpretation of the inverted cubes in terms of geologic facies, net-to-gross ratio, and static connectivity among depositional geobodies. Three subenvironments within the targeted reservoir interval were recognized using a combination of shale volume and [Formula: see text]-inverted cubes. These were used to generate 3D geobodies and a net-pay (...)

    A Neat Embedding Theorem For Expansions Of Cylindric Algebras.Tarek Sayed-Ahmed & Basim Samir - 2007 - Logic Journal of the IGPL 15 (1):41-51.
    We generalize two classical results on cylindric algebra to certain expansions of cylindric algebras where the extra operations are defined via first order formulas. The first result is the Neat Embedding Theorem of Henkin and the second is Monk's classical non-finitizability result of the class of representable algebras. As a corollary we obtain known classical results of Johnson and Biro published in the Journal of Symbolic logic.

    Beyond Humanism and Postmodernism: Theorizing a Feminist Practice.Sara Ahmed - 1996 - Hypatia 11 (2):71 - 93.
    The model of feminism as humanist in practice and postmodern in theory is inadequate. Feminist practice and theory directly inform each other to displace both humanist and postmodern conceptions of the subject. An examination of feminism's use of rights discourse suggests that feminist practice questions the humanist conception of the subject as a self-identity. Likewise, feminist theory undermines the postmodern emphasis on the constitutive instability and indeterminacy of the subject.

    Corporate Governance and Ethics: A Feminist Perspective.Silke Machold, Pervaiz K. Ahmed & Stuart S. Farquhar - 2008 - Journal of Business Ethics 81 (3):665-678.
    The mainstream literature on corporate governance is based on the premise of conflicts of interest in a competitive game played by variously defined stakeholders and thus builds explicitly and/or implicitly on masculinist ethical theories. This article argues that insights from feminist ethics, and in particular ethics of care, can provide a different, yet relevant, lens through which to study corporate governance. Based on feminist ethical theories, the article conceptualises a governance model that is different from the current normative orthodoxy.

  34. Differences That Matter: Feminist Theory and Postmodernism.Sara Ahmed - 1998 - Cambridge University Press.
    Differences That Matter challenges existing ways of theorising the relationship between feminism and postmodernism which ask 'is or should feminism be modern or postmodern?' Sara Ahmed suggests that postmodernism has been allowed to dictate feminist debates and calls instead for feminist theorists to speak (back) to postmodernism, rather than simply speak on (their relationship to) it. Such a 'speaking back' involves a refusal to position postmodernism as a generalisable condition of the world and requires closer readings of what postmodernism (...)

    Business relations rely on shared perceptions of what is acceptable/expected norms of behavior. Immense expansion in transnational business made rudimentary consensus on acceptable business practices across cultural boundaries particularly important. Nonetheless, as more and more nations with different cultural and historical experiences interact in the global economy, the potential for misunderstandings based on different expectations is magnified. Such misunderstandings emerge in a growing literature on "improper" business practices – articulated from a narrow cultural perspective. This paper reports an ongoing research (...)

    The Class of Infinite Dimensional Neat Reducts of Quasi‐Polyadic Algebras is Not Axiomatizable.Tarek Sayed Ahmed - 2006 - Mathematical Logic Quarterly 52 (1):106-112.
    SC, CA, QA and QEA denote the classes of Pinter's substitution algebras, Tarski's cylindric algebras, Halmos' quasi-polyadic algebras and quasi-polyadic equality algebras, respectively. Let ω ≤ α < β and let K ∈ {SC,CA,QA,QEA}. We show that the class of α -dimensional neat reducts of algebras in Kβ is not elementary. This solves a problem in [3]. Also our result generalizes results proved in [2] and [3].

    Omitting Types for Algebraizable Extensions of First Order Logic.Tarek Sayed Ahmed - 2005 - Journal of Applied Non-Classical Logics 15 (4):465-489.
    We prove an Omitting Types Theorem for certain algebraizable extensions of first order logic without equality studied in [SAI 00] and [SAY 04]. This is done by proving a representation theorem preserving given countable sets of infinite meets for certain reducts of ?- dimensional polyadic algebras, the so-called G polyadic algebras (Theorem 5). Here G is a special subsemigroup of (?, ? o) that specifies the signature of the algebras in question. We state and prove an independence result connecting our (...)

    YAP and TAZ in Epithelial Stem Cells: A Sensor for Cell Polarity, Mechanical Forces and Tissue Damage.Ahmed Elbediwy, Zoé I. Vincent‐Mistiaen & Barry J. Thompson - 2016 - Bioessays 38 (7):644-653.
    The YAP/TAZ family of transcriptional co‐activators drives cell proliferation in epithelial tissues and cancers. Yet, how YAP and TAZ are physiologically regulated remains unclear. Here we review recent reports that YAP and TAZ act primarily as sensors of epithelial cell polarity, being inhibited when cells differentiate an apical membrane domain, and being activated when cells contact the extracellular matrix via their basal membrane domain. Apical signalling occurs via the canonical Crumbs/CRB‐Hippo/MST‐Warts/LATS kinase cascade to phosphorylate and inhibit YAP/TAZ. Basal signalling occurs (...)

    A Phenomenology of Whiteness.Sara Ahmed - 2007 - Feminist Theory 8 (2):149-168.
    The paper suggests that we can usefully approach whiteness through the lens of phenomenology. Whiteness could be described as an ongoing and unfinished history, which orientates bodies in specific directions, affecting how they `take up' space, and what they `can do'. The paper considers how whiteness functions as a habit, even a bad habit, which becomes a background to social action. The paper draws on experiences of inhabiting a white world as a non-white body, and explores how whiteness becomes worldly (...)

    Neat Embeddings as Adjoint Situations.Tarek Sayed-Ahmed - 2015 - Synthese 192 (7):1-37.
    Looking at the operation of forming neat $\alpha $ -reducts as a functor, with $\alpha $ an infinite ordinal, we investigate when such a functor obtained by truncating $\omega $ dimensions, has a right adjoint. We show that the neat reduct functor for representable cylindric algebras does not have a right adjoint, while that of polyadic algebras is an equivalence. We relate this categorial result to several amalgamation properties for classes of representable algebras. We show that the variety of cylindric (...)

    "The Uncertain Science" argues that sociology has not freed itself from the influence of philosophy, and specifically from the search for certainty. This "foundationalism" which is characteristic of Western thought has influenced both the method adopted by sociologists, and their research practices. The authors criticize sociology for its formalism, arguing that this blunts the radicalism of its project.

If options have objective values, then it should always be rationally permissible for an agent to choose an option if they are certain that the option uniquely maximizes objective value. But, as we show, if options have objective values and evidential decision theory is true, then it is not always rationally permissible for an agent to choose an option if they are certain that the option uniquely (...)
