Optical injection locking and optical phase-lock loops have been used for laser synchronization. The use of a combined optical injection locking and phase-lock loop system is proposed here. We have taken into account the modification of the slave laser phase response induced by the injection locking to calculated the phase-error signal spectrum and the phase-error variance for an optical inject...

This paper proposes compensated methods to cancel the effects of charge injection error on switched-current Divider Circuits. Algorithmic structures of current dividers are presented and the final charge injection error is evaluated for each Algorithm. So, compensated methods to cancel this error are proposed.

Fault injection is a widely used technique to test the robustness of software systems and to find bugs in applications. We focus on using fault injection to judge the quality of error handling in applications. Even mature applications have serious bugs in error handling [3]. To find all bugs related to bad error handling when using a certain API one has to do exhaustive fault injection, i.e., t...

Nowadays, soft errors in logic circuits are becoming increasingly important. This is especially true in the ever shrinking nanometer technologies, and aerospace applications where soft errors are more prevalent. Previous soft error injection simulation methods using FPGAs have usually been limited to small test circuits such as ISCAS89, or parts of a larger circuit. Other software approaches ha...

In order to assess the robustness of software-based fault-tolerance methods, extensive tests have to be performed that inject faults, such as bit flips, into hardware components of a running system. Fault injection commonly uses either system simulations, resulting in execution times orders of magnitude longer than on real systems, or exposes a real system to error sources like radiation. This ...

Completely handling SQL injection consists of two activities: properly protecting the system from malicious input, and preventing any resultant error messages caused by SQL injection from revealing sensitive information. The goal of this research is to assess the relative effectiveness of unit and system level testing of web applications to reveal both error message information leak and SQL inj...

The effects of variations in the workload input when estimating error detection coverage using fault injection are investigated. Results from scanchain implemented fault injection experiments using the FIMBUL tool on the Thor microprocessor show that the estimated error non-coverage may vary by more than five percentage units for different workload input sequences. A methodology for predicting ...
