    Muslim scholars and technological volition

    , Article Technology in Society ; Volume 61 , 2020 Ravanbakhsh, R ; Taqavi, M ; Sharif University of Technology
    Elsevier Ltd  2020
    Abstract
    What purpose, according to Muslim scholars, should technological development serve? To answer this question, first we explain the views of seven Muslim scholars who have theorized about technology from an Islamic viewpoint. We then set out Carl Mitcham's fourfold analysis of technology, and summarize the views of philosophers of technology on technological volition. This places us in a position to classify Muslim scholars' opinions on technological development under seven broad headings, namely: meeting human beings' needs, implementation of an Islamic culture and lifestyle, serving human beings, serving nature, understanding the splendor of creation, providing personal and social happiness,... 

    Elaborating Religious Guidelines for Technological Development

    , Ph.D. Dissertation Sharif University of Technology Ravanbakhsh, Rostam (Author) ; Taqavi, Mostafa (Supervisor)
    Abstract
    Some philosophers and thinkers have made serious criticisms of modern technology, considering it the cause of major problems. These critiques and problems have motivated some philosophers to think of alternatives for technology. Andrew Feenberg, one of the scholars seeking alternatives for technology, argues that the modern technical system is derived from the values of capitalism and serves a select few. As a diagnosis, Feenberg considers the capitalistic values to be the root of modern technological crises and as a prescription, he recommends a “democratic technological design system”. Feenberg has proposed no criteria for evaluating the values that could be incorporated into the... 

    A Historical Analysis of the Evolution of Dominant Industrial Development Approaches in the Age of Pahlavi in Iran

    , M.Sc. Thesis Sharif University of Technology Hosseini, Siavash (Author) ; Souzanchi Kashani, Ebrahim (Supervisor)
    Abstract
    Our country in no measure is considered as an industrial one, despite its chain of small, medium and large industries. The vague, general “developing” term might be the best term to assign to economic-industrial condition of our country. We have a fairly limited number of big industrial firms (BIF) which could continue operation without state’s supports in a world BIFs are considered as the key indices in industrial development. The question comes to mind with reading what came above is this study’s main question, “What went wrong?”. This study follows the historical approach to the question through a comprehensive case study. Historical case-study thus is our main research approach here.... 

    Design for well-being: The fourth generation of technology development

    , Article Technology in Society ; Volume 67 , November , 2021 ; 0160791X (ISSN) Kafaee, M ; Ansarian, Z ; Taqavi, M ; Heidari, S ; Sharif University of Technology
    Elsevier Ltd  2021
    Abstract
    Despite the importance of well-being, few studies have been conducted on the relationship between well-being and technology. In this paper, the development of technology from the perspective of well-being studies are divided into three generations. In higher generations, the main criterion of technology development becomes more comprehensive, in order to decrease the side effects of technology. We introduce the fourth generation in which well-being is the main criterion of the design process. Although it may not seem necessary to say that the purpose of most technologies is implicitly well-being, we show that the domination of physical pleasure in terms of “use and convenience” in the modern... 

    Turboexpander Technology Development Model and Display Roadmap for Pressure Reducing System based Energy Recovery by Turboexpander

    , M.Sc. Thesis Sharif University of Technology Ramezani, Roohollah (Author) ; Saboohi, Yadollah (Supervisor)
    Abstract
    High pressure natural gas is transported from processing plants to end users via a network of natural gas system. Pressure reduction along the transport system is compensated in compressor stations. High pressure natural gas flows in to distribution network in demand center which operates at medium pressure. Medium pressure gas is transferred to end users who can use natural gas with low pressure. Therefore, pressure of natural gas is reduced consequently when gas flows from transport systems to distribution network and end users. Work is dissipated during pressure reduction which otherwise could be converted in to power.A technology that could be utilized for conversion of pressure work in...

    Abstract
    This article concerns the notion of methodology in strategic management of R&D/technology. Though development of new tools and methods has received much attention during the recent decades, attention to understanding methodologies has remained disproportionally low. In this study we distinguish two methodologies that are used in strategic management of R&D/technology: planning methodology and evolutionary learning methodology. We mainly focus on defining and describing the origins, nature, and characteristics of the latter. We propose a framework for methodology selection by investigating context, content, and process factors. Using this framework, we provide supportive evidence for...

    Proposal of a new design for valveless micropumps

    , Article Scientia Iranica ; Volume 18, Issue 6 , December , 2011 , Pages 1261-1266 ; 10263098 (ISSN) Afrasiab, H ; Movahhedy, M. R ; Assempour, A ; Sharif University of Technology
    2011
    Abstract
    A new design for a valveless micropumping device has been proposed that integrates two existing pumping technologies, namely, the wall induced traveling wave and the obstacle-type valveless micropump. The liquid in the microchannel is transported by generating a traveling wave on the channel, while the placing of two asymmetric trapezoid obstacles, along the centerline of the channel inlet and outlet, leads to a significant (up to seven times) increase of the net flow rate of the device. The effectiveness of this innovative design has been proved through a verified three-dimensional finite element model. FluidStructure Interaction (FSI) analysis is performed in the framework of an Arbitrary...
