Autonomous thruster failure recovery for underactuated spacecraft
Thruster failures historically account for a large percentage of failures that have occurred on orbit. Therefore, autonomous thruster failure detection, isolation, and recovery (FDIR) is an essential component to any robust space-based system. This thesis focuses specifically on developing thruster …

Approximate failure recovery in distributed graph processing systems
… become faster and more scalable. However, after failures, distributed graph processing systems either largely rely on proactive fault tolerance techniques such as checkpointing, or use no fault tolerance mechanisms at all and simply restart computation. The former approach entails significant …

Separating conflict-recovery from failure-recovery in distributed consensus
… ensure that the system can mask or recover from failures. Current state-of-the-art consensus protocols re-use their failure-recovery mechanism to resolve ordering conflicts. The thesis of this dissertation is that it is feasible to separate the mechanisms for conflict-recovery and …

Zorro: zero-cost reactive failure recovery in distributed graph processing
… existing frameworks either lack the ability to recovery from failures or support proactive recovery methods. Proactive recovery methods like checkpointing incur high overheads during failure-free execution making failure recovery an expensive operation. Our hypothesis is that reactive recovery …

Hierarchical Plan Formation and Failure Recovery in the Flight Domain
… architecture that can perform both planning and recovery planning in the flight domain.

Edge disjoint spanning trees and failure recovery in data communication networks
Thesis (Ph.D.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 1983.

Capacity provisioning, failure recovery and throughput analysis for low earth orbit satellite constellations
… capacity for recovering from a link or node failure are examined. In both cases, we use a method of \cuts on a graph" to obtain lower bounds on capacity requirements and subsequently find algorithms for routing and failure recovery that meet these bounds. Finally, we quantify the benefits of …

The Toppler Effect : irregular leader transitions and the rate of state failure recovery
State failure is becoming increasingly prevalent across the globe, creating human suffering, black markets, lost economic opportunities, and safe havens for militant actors. It is imperative that the international community find a way to combat state failure. This study investigates the effects of …

SpiderNet: A Quality -Aware Service Composition Middleware
… connections to achieve high-quality and failure-resilient service composition. Second, we present two different designs for the core SpiderNet: utility SpiderNet and P2P SpiderNet, which are designed for managed enterprise systems and self-organized peer-to-peer systems, respectively. The …

Investigating system resilience in distributed evolutionary GAN training
… on systems that encounter frequent node failures. When faced with a single node failure, Lipizzaner's entire experiment comes to a halt and must be restarted. We see a need for increasing Lipizzaner's resilience to such failures and do the following. We apply a combination of …

Trust-aware virtual network embedding algorithms for wireless sensor networks
… objective, our first approach addresses node failures during mapping with a pioneering heuristic— the survivable trust-aware virtual wireless sensor networks (STA-VWSN) algorithm. It employs a failure recovery procedure, prioritizing nodes based on the technique for order of preference by …

Design, Development and Implementation of Intelligent Algorithms to Increase Autonomy of Quadrotor Unmanned Missions
… environments. Healthy flights, flights with failures, flight with GPS-denied navigation and post-failure recovery are presented.</p>

Design and evaluation of network survivability schemes for correlated multi-failure scenarios
… a central concern, as even a single link or node failure can cause widespread service disruption for thousands of users or more. Now over the years, a full range of network survivability schemes have been developed for packet routing and optical switching networks. Indeed, the open research …

Design and Implementation of a Network Server in LibrettOS
… trusted computing base contracts; (iii) enables failure recovery, which is an important feature supported by a multiserver OS. This thesis proposes a network server for LibrettOS, an operating system based on rumprun unikernels and the Xen Hypervisor developed by Virginia Tech. The proposed …

Storage system design for non-volatile byte-addressable memory using consistent and durable data structures
… same versioning scheme also enables rollback for failure recovery. When compared to a memory-backed Berkeley DB B-Tree, our prototype- based results show that a CDDS B-Tree can increase put and get throughput by 74% and 138%. Tembo, a CDDS B-Tree enabled distributed Key-Value system, has up to …

Testing advanced transactions in service-based software systems
… in terms of response time efficiency, failure recovery, flexibility and support for long running and complex business applications. This thesis focuses on another quality dimension which is the testing of WS transactions. In it, the focus of testing is to detect possible faults or …

Service recovery and the elusive paradox: an examination of the effects of magnitude of service failure, service failure responsiveness, service guarantee and additional recovery effort on service recovery comes
Service failure and recovery remain critical issues for both academicians and marketing practitioners. Defined as a service provider’s response to a failed service, service recovery can mean the difference between a firm’s success and failure, for increasing customer retention and limiting customer …

Towards a Scalable Docker Registry
Containers are an alternative to virtual machines rapidly increasing in popularity due to their minimal overhead. To help facilitate their adoption, containers use management systems with central registries to store and distribute container images. However, these registries rely on other, …

Using object process methodology to develop interfaces and smart electronic procedures for simulated telerobotic operations
… has several functions, including automating failure recovery and showing automated customize procedures to restore system to pre-failure configuration. This thesis considered only one application and further applications are needed to demonstrate the utility of OPM in the broader HFE domain. …
