    Seismic Risk and Resilience of a System of Systems: Analysis of a Virtual City

    , M.Sc. Thesis Sharif University of Technology Lesani Shadbad, Ali (Author) ; Mahsoli, Mojtaba (Supervisor)
    Abstract
    The fundamental objective of this study is to present seismic hazard, risk and resilience assessment of a virtual city using sampling and agent-based simulation in two levels of refinement. In this context, hazard is the exceedance probability of ground shaking intensity, risk is exceedance probability of measures such as loss, and resilience is the ability to quickly recover after a hazard event. This study utilizes the Rtx risk and resilience assessment framework established at the Center for Infrastructure Sustainability and Resilience Research (INSURER) at Sharif University of Technology. This framework employs multiple interacting probabilistic models to quantify the risk and... 

    Investment Valuation Model for Retrofit of Infrastructure under Uncertainty

    , M.Sc. Thesis Sharif University of Technology Asghari, Vahid (Author) ; Haj Kazem Kashani, Hamed (Supervisor)
    Abstract
    Infrastructure systems play a critical role in the economic and social activities of a community. Effective and continuous performance of these infrastructure systems is essential to the welfare and prosperity of the communities. Infrastructure systems comprise networks of interdependent assets that are built through a long and costly process. These assets are subject to a variety of factors that reduce the performance and reliability over time. These factors also increase the vulnerability of infrastructure assets in face of future probable hazards. In order to ensure the continuous and uninterrupted performance of infrastructure assets in post-hazard situations, asset managers should plan... 

    System Design Methodology of Airbag Control Unit in Compliance with ISO 26262

    , M.Sc. Thesis Sharif University of Technology Mofatteh, Mohammad Yaser (Author) ; Fotowat Ahmadi, Ali (Supervisor) ; Safarian, Amin Ghasem (Co-Supervisor)
    Abstract
    Various safety systems have been designed and developed in recent decades, but one of the most important issues is the improvement of safety of such systems and that is the goal of this research. In this thesis, while introducing different methods of designing an electronic system, we designed one of these safety systems: the Airbag system in accordance with ISO 26262 by considering standard requirements, prediction of potential hazards of the system, and its safe design at the system level. The designed system is capable of detecting the car crash in a precise and timely maner. The airbag will deploy within 45 milliseconds protecting the health and safety of occupants of the car and in...
