    Model-Driven Approach for Software Process Line Engineering

    , Ph.D. Dissertation Sharif University of Technology Agh, Halimeh (Author) ; Ramsin, Raman (Supervisor)
    Abstract
    Constructing bespoke software development processes according to the specifications of the project at hand has become a crucial issue, but defining a separate process for each potential project context is a time-consuming and costly endeavor. The Software Process Line (SPrL) is a concept similar to the Software Product Line (SPL), except that it belongs to the domain of software development process engineering; it allows software processes to be constructed according to a specific context by reusing core process assets. Tailoring a process line for constructing project-specific processes is time-consuming and error-prone if done manually; therefore, it is important that a high...

    , Article IEEE Transactions on Parallel and Distributed Systems ; Vol. 22, issue. 5 , 2011 , p. 817-832 ; ISSN: 10459219 Moraveji, R ; Moinzadeh, P ; Sarbazi-Azad, H ; Zomaya, A.Y ; Sharif University of Technology
    Abstract
    In this paper, a diverse range of routing algorithms is classified into a new family of routings called zone-ordered label-based routing algorithms. The proposed classification is based on three common steps (factors) for generating such routings, namely, graph labeling, deadlock-free zones, and zone ordering. The main goal of this classification is to define several new routing concepts and streamline the knowledge on routing algorithms. Following the classification, a novel methodology is proposed to generate routing algorithms for irregular networks. The methodology uses the three mentioned steps to generate deadlock-free routings. Consequently, the methodology-based routings fall into...

    , Article European Biophysics Journal ; Vol. 43, Issue. 12 , 2014 , pp. 595-602 ; ISSN: 1432-1017 Baroji,Y. F ; Oddershede, L. B ; Reihani, S. N. S ; Bendix, P. M ; Sharif University of Technology
    Abstract
    Membrane nanotubes, ubiquitous in cellular systems, adopt a spectrum of curvatures and shapes that are dictated by their intrinsic physical characteristics as well as their interactions with the local cellular environment. A high bending flexibility is needed in the crowded cytoplasm where tubes often need to bend significantly in the axial direction at sub-micron length scales. We find the stiffness of spontaneously formed membrane nanotubes by measuring the persistence length of reconstituted membrane nanotubes freely suspended in solution and imaged by fluorescence microscopy. By quantifying the tube diameter we demonstrate for the first time that the persistence length scales linearly...
