    Abstract
    Owing to the inherent incompatibility with water, cyanation of aryl halides may be the most challenging category of palladium-catalyzed coupling reactions. The major challenges are attributed to the catalyst deactivation by the soluble cyanide (CN−) ions and desirable conversions only could be obtained by employing toxic organic solvents. The current minireview highlights mechanistic insights and breakthrough achievements for this reaction in the aqueous media

    Automated Code Reviewer Recommendation for Pull Requests

    , M.Sc. Thesis Sharif University of Technology Moosa Reza, Mina Sadat (Author) ; Heydarnoori, Abbas (Supervisor)
    Abstract
    Nowadays, by distributed software development growth based on pull-requests, it is possible to review code changes before integrating into the master program by a third-party, informally and tool-based which is called Modern Code Review (MCR). Effectively performing MCR can facilitate the software evolution phase through reducing post-release defects. In MCR, after sending the pull request, the developer invites appropriate reviewers to inspect his code. Due to the high volume of requests and potential reviewers in many projects, selecting the appropriate reviewer is difficult and time consuming. Previously, a variety of recommender systems have been proposed that use methods based on... 

    A Symmetric Kernel Matrix for Community Detection in Directed Complex Networks

    , M.Sc. Thesis Sharif University of Technology Firouzi, Hamid Reza (Author) ; Roosta Azad, Reza (Supervisor) ; Zarei, Mina (Co-Advisor)
    Abstract
    Complex directed networks are widely used in representing, modeling and summarizing various homo and heterogeneous real networks such as protein-protein interactions, social and twitting networks, brain connectomes, chipsets mapping and marketing. While working on undirected networks in the hope for detecting communities or any other static and dynamic structures, has been on agenda of many physician and computer scientists, dealing with directed ones seems more challengeable for quick advances. Availability of theoretical basis especially symmetric adjacency matrix recommends modeling with undirected graphs but we believe that directed graphs are more general and practical to model real...

    Elsevier B.V  2021
    Abstract
    Supplier selection is an important and challenging problem in sustainable supply chain management. We propose a dynamic decision support system (DSS) for sustainable supplier selection in circular supply chains. Unlike the linear take-make-waste-dispose production systems, circular supply chains are nonlinear make-waste-recycle production systems with zero-waste vision. The proposed DSS allows users to customize and weight their economic, social, and circular criteria with a fuzzy best-worst method (BWM) and select the most suitable supplier with the fuzzy inference system (FIS). Machine learning is used to maintain and synthesize the criteria scores for the suppliers after each supplier...

    Abstract
    The increasing level of customer awareness and application of environmental laws by governments, on the one hand, and the increasing number of competitors, on the other hand, has obliged industry owners to include green activities in the design of the supply chain network. Green activities include any type of action that reduces environmental degradation. Hence, this study seeks to develop a bi-objective, mixed integer linear programming (MILP) model for designing a green supply chain network. In the proposed model, the minimisation of costs and detrimental environmental effects are discussed. LP metric method is used to solve the bi-objective model and the proposed model is run by using...

    Process Design of Ionic Liquid-Based CO2 Capture with Consideration of Economic and Environmental Issues

    , M.Sc. Thesis Sharif University of Technology Eidi, Ali (Author) ; Rashtchian, Davood (Supervisor) ; Adibi, Mina (Co-Supervisor)
    Abstract
    Concerns have increased about global warming caused by CO2 emissions in the atmosphere. At the moment, carbon capture and storage is the best available solution. Among the current technologies for CCS, amine-based chemical absorption appears to be the most common method. Amines show several inherent drawbacks such as high vapor pressure, high energy consumption in regeneration, corrosivity and degradability. So, researchers have developed new solvents with the foresight of being superior to amines. Ionic liquids (ILs) are among the most suitable alternatives. The most prominent feature of ILs is their tunable thermophysical properties. In this work, physical absorption by ILs is chosen as...
