  1. 1. Lineage-driven Fault Injection for Actor-based Programs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yonas Ghidei; [2019]
    Keywords : ;

    Abstract : Lineage-driven fault injection (LDFI) is an approach for finding bugs or faults in distributed systems. Its current state-of-the-art implementation, Molly, takes programs written in the logic programming language Dedalus as its input. The problem is that Dedalus is a small and obscure language, used to serve as a proof of concept for Molly. READ MORE

  2. 2. Simulation of chaos engineeringfor Internet-scale software with ns-3

    University essay from KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Author : Anton Zubayer; Tai Luong; [2018]
    Keywords : ;

    Abstract : AbstractChaos engineering is the practice of volitionally fault injecting in to a built system with the main purpose of finding the eventual bugs existed in the system before the actual system error occurs. One of the pioneers in this practice is the Simian army, a part of Netflix, where they used random fault injection and linage driven fault injection in its own enormous system with the purposes of suggesting either a relevant approach to chaos engineering or to propose methods of how to uncover the hidden weaknesses.

  3. 3. Radiation Hardened System Design with Mitigation and Detection in FPGA

    University essay from Linköpings universitet/Datorteknik

    Author : Hampus Sandberg; [2016]
    Keywords : FPGA; radiation; TMR; fault mitigation; fault injection; fault detection;

    Abstract : FPGAs are attractive devices as they enable the designer to make changes to the system during its lifetime. This is important in the early stages of development when all the details of the final system might not be known yet. READ MORE

  4. 4. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap; Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Kim Torberntsson; Vidar Stiernström; [2016]
    Keywords : numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

    Abstract : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. READ MORE

  5. 5. Stepless fault injection for electrohydraulic actuator

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Erik Jönsson; [2015]
    Keywords : Technology and Engineering;

    Abstract : One of the cases for testing the BorgWarner GEN V clutch is to see if pump and motor malfunctions are detected by the software. Until now there have been a couple of fixed configurations testing clutches with different faults. READ MORE
