1. On the Effects of Soft Errors in Embedded Control Systems
Abstract : This thesis investigates techniques for making closed loop control systems fault-tolerant and robust with respect to soft errors occurring in the computer hardware. Soft errors are caused by transient faults that alter the binary values stored in latches, flip-flops and other state elements without causing any permanent damage to the hardware. READ MORE

2. On Efficient Measurement of the Impact of Hardware Errors in Computer Systems
Abstract : Technology and voltage scaling is making integrated circuits increasingly susceptible to failures caused by soft errors. The source of soft errors are temporary hardware faults that alter data and signals in digital circuits. READ MORE

3. Background radiation and soft errors in CMOS circuits
Abstract : Background radiation in natural environments from ground level to airplane flight altitudes consists of electrons, neutrons, protons, pions, muons, and other types of particles. These particles originate either from cosmic rays or from radioactive decay. READ MORE

4. Techniques for Tolerating Soft Errors in Brake-by-Wire Systems
Abstract : This thesis addresses the problem of tolerating soft errors in brake-by-wire systems. Soft errors are caused by ionizing particles and manifest themselves as bit-flips in memory registers, latches, and flip-flops. As transistors are shrunk to sustain Moore's law, the frequency of such radiation-induced faults increases. READ MORE

5. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing
Abstract : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. READ MORE
