    The study of network effects on research impact in Africa

    , Article Science and Public Policy ; Volume 48, Issue 4 , 2021 , Pages 462-473 ; 03023427 (ISSN) Tahmooresnejad, L ; Beaudry, C ; Mirnezami, S. R ; Sharif University of Technology
    Oxford University Press  2021
    Abstract
    This paper studies the relationship between the position of individual scientists within co-authorship networks and their scientific performance. Using co-authorship data from African scientists in the Health and Medical Sciences within a timespan of 15 years (2000–2015), we characterize the collaboration networks and calculate centrality measures for each scientist to explore how scientific production and impact can be associated with their position within the network. Our findings reveal that authors who occupy a better position within their network and are deemed to actively collaborate with others also have a higher research impact. In this regard, South African scientists do not differ... 

    Does experiencing international research collaboration permanently affect the impact of scientific production? evidence from africa

    , Article Journal of African Economies ; Volume 31, Issue 3 , 2022 , Pages 251-271 ; 09638024 (ISSN) Mirnezami, S. R ; Beaudry, C ; Sharif University of Technology
    Oxford University Press  2022
    Abstract
    This paper examines the effect of experiencing a research collaboration between African scientists and their international partners on the African scientists' research impact, measured by scores based on the number of citations and journal impact factor. Using a difference-in-difference regression analysis on publication data of African scientists, the results show that international research collaboration in a given year has a positive and significant effect on research impact, which lasts in the subsequent years. The presence of such permanent effect suggests a sort of 'permanent learning by international collaboration'. The positive effect of international collaboration on research...

    Corporate entrepreneurship (CE) has been drawing mounting interest in recent decades. Entrepreneurial behavior holds paramount importance in organizational research, since entrepreneurship is essential for modern organizations success. Each scholarly has partly investigated the concept. This paper seeks to present the result of a systematic review of the prominent studies about CE while elaborating on fundamental concepts. To do so, we have conducted statistical analyses of significant 336 studies while categorizing CE literature on a thematic basis. The analyses suggest that CE literature may fall in three main categories, i.e., antecedent, process, and consequence. The paper proceeds to...

    Simulation, design optimization, and experimental validation of a silver SPND for neutron flux mapping in the Tehran MTR

    , Article Nuclear Engineering and Technology ; Volume 52, Issue 12 , 2020 , Pages 2852-2859 Saghafi, M ; Ayyoubzadeh, S. M ; Terman, M. S ; Sharif University of Technology
    Korean Nuclear Society  2020
    Abstract
    This paper deals with the simulation-based design optimization and experimental validation of the characteristics of an in-core silver Self-Powered Neutron Detector (SPND). Optimized dimensions of the SPND are determined by combining Monte Carlo simulations and analytical methods. As a first step, the Monte Carlo transport code MCNPX is used to follow the trajectory and fate of the neutrons emitted from an external source. This simulation is able to seamlessly integrate various phenomena, including neutron slowing-down and shielding effects. Then, the expected number of beta particles and their energy spectrum following a neutron capture reaction in the silver emitter are fetched from the...

    Abstract
    Sensor networks have recently emerged as a premier research topic. Sensor networks pose a number of new conceptual and optimization problems. Some, such as location, deployment, and tracking, are fundamental issues, in that many applications rely on them for needed information. While designing the sensor networks according to performed computation, the limited number of sensors to cover an area will be considered, so the proper placing of this limited number of sensors will cause costs to reduce regarding to coverage and development of the network in the next stage. In this paper we will present a genetic algorithm to solve the designing issue of the sensor network. The most important...

    Abstract
    The importance of scientific collaborations is mainly because of the professional learning obtained from the formation of research connections. Each researcher brings a feature and advantage to the research team, such as mastering a particular topic and its subdivisions or improving team thinking. The importance of collaboration is doubled when researchers collaborate at the international level, resulting in access to up-to-date resources and equipment, consequently increasing the quantity, quality, and impact of research activities. The primary purpose of this study is to investigate the effect of international collaboration of faculty members on the centrality of the university network... 

    Design and implementation of a PC-based digital synchronous detection system for biological signal measurement

    , Article 2007 5th Student Conference on Research and Development, SCORED, Selangor, 11 December 2007 through 12 December 2007 ; 2007 ; 1424414709 (ISBN); 9781424414703 (ISBN) Gan, K. B ; Zahedi, E ; Mohd Ali, M. A ; Sharif University of Technology

    Abstract
    A PC-based digital lock-in amplifier was implemented completely in software (Labview) for photoplethysmograph (PPG) measurement. Experiments carried out to evaluate the performance of the amplifier show that the system can recover the signals up to 40 dB below the interference (ambient light). This system can be customized later to measure the trans-abdominal PPG signal of pregnant women for fetal heart rate detection. ©2007 IEEE  

    Positioning System for a Personal Research Space

    , M.Sc. Thesis Sharif University of Technology Ayoughi, Negin (Author) ; Mahdavi-Amiri, Nezamoddin (Supervisor)
    Abstract
    We study the Personal Research Space (PRS), that is, the collection of documents a researcher gathers for her research project in order to fnd solutions for a common problem in academic research. During the orientation phase, before the academic research team makes fnal decisions on the course of its studies, abrupt change of directions of studies are common. Ideally, documents in this process are arranged in such a way that time spent in a topic saves a good portion of the time required for research studies in another. We propose an optimization model that provides solutions to parallel this ideal arrangement. PRS as an integral part of the global research system, a highly complex and...

    , Article International Journal of Production Economics ; Vol. 158, issue , 2014 , p. 18-27 Hassanzadeh, F ; Modarres, M ; Nemati, H. R ; Amoako-Gyampah, K ; Sharif University of Technology
    Abstract
    Pharmaceutical drug Research and Development (R&D) outsourcing to contract research organizations (CROs) has experienced a significant growth in recent decades and the trend is expected to continue. A key question for CROs and firms in similar environments is which projects should be included in the firm's portfolio of projects. As a distinctive contribution to the literature this paper develops and evaluates a business support tool to help a CRO decide on clinical R&D project opportunities and revise its portfolio of R&D projects given the existing constraints, and financial and resource capabilities. A new mathematical programming model in the form of a capital budgeting problem is...
