Testing and Diagnosing Comparison Faults of TCAMs with Asymmetric Cells
IEEE Transactions on Computers, 2012Ternary content addressable memory (TCAM) is a key component in various digital systems due to its fast lookup operation. Symmetric and asymmetric TCAM cells are two widely used cells for implementing a TCAM array. This paper presents several comparison fault models of TCAMs with asymmetric cells based on electrical defects.

Masking asymmetric line faults using semi-distance codes
[1988] The Eighteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003The authors propose a masking method for asymmetric line faults in LSIs using semidistance codes, which are a class of nonlinear codes. Faults caused by open or short circuit defects in line areas of LSIs can be made asymmetric by controlling the bus driver and the bus terminal gates. The conditions required for codes to mask these faults are clarified,

Asymmetrical fault analysis using the bus impedance matrix
Proceedings of the Institution of Electrical Engineers, 1978The method of the busbar impedance matrix is applied to the solution of asymmetrical faults through the use of sequence impedances and Kron's constraint matrix. An algorithm is proposed to facilitate the routine solution of complex configurations including simultaneous and cross-country faults.

Efficient Fault Tolerance for Stateful Serverless Computing with Asymmetric Logging
ACM Transactions on Computer SystemsServerless computing separates function execution from state management. Simple retry-based fault tolerance might corrupt the shared state with duplicate updates. Existing solutions employ log-based fault tolerance to achieve exactly-once semantics, where every single read or write to the external state is associated with a log for deterministic replay.

Open transistor fault detection in asymmetric multilevel inverter
2015 IEEE International Conference on Signal Processing, Informatics, Communication and Energy Systems (SPICES), 2015The number of power semiconductor switches and DC sources will increase with the increase in the number of levels of output voltage of the multilevel inverter. As the number of power semiconductor switches increases, the possibility of its failure and hence the breakdown of the inverter operation also escalate in a nonlinear manner.

Fast generator protection against internal asymmetrical faults
IEEE Transactions on Power Apparatus and Systems, 1977An on-line digital computer technique for the protection of a generator against internal asymmetrical faults is described in this paper. The proposed technique relies on the detection of a second harmonic component in the field current at the onset of a fault in the armature winding.
