Test Pattern Generation and Signature Analysis for Burst Errors
نویسنده
چکیده
In testing certain systems, checking for burst errors is important. This is due to the fact that errors are confined to a certain number of bits. If signature analysis is used to test a circuit then the testing capabilities depend on the polynomial that defines the linear feedback shift register (LFSR) used in the test. In this paper we show that the LFSR that is suitable for checking for burst errors is not suitable for test pattern generation. We propose a method to modify the LFSR that performs signature analysis efficiently into a nonlinear feedback shift register (NLFSR) that is suitable for test pattern generation.

متن کاملThe distinctive trace elements signature of the less-evolved MORB materials in the south of Birjand ophiolites
Mafic rocks including basalts and gabbros are the main constituents of Birjand ophiolites. They are found in several places and show low grade metamorphism in the field and under the microscope. Chondrite-normalized REE patterns for basalts and gabbros indicate that these rocks are transitional-enriched to depleted mid-oceanic ridge basalts respectively. Otherwise, N-MORB normalized trace eleme...

In this paper, we propose an approach for automatic generation of novel intrusion signatures. This approach can be used in the signature-based Network Intrusion Detection Systems (NIDSs) and for the automation of the process of intrusion detection in these systems. In the proposed approach, first, by using several one-class classifiers, the profile of the normal network traffic is established. ...
متن کاملAnalysis of Changes on Mean Particle Size in a Fluidized Bed using Vibration Signature
Vibration signals were measured in a lab-scale fluidized bed to investigate the changes in particle sizes. Experiments were carried out in the bed with a different mass fraction of coarser particles at different superficial gas velocities, and probe heights. The S-statistic test evaluates the dimensionless squared distance between two attractors reconstructed from time series of vibration signa...
متن کاملFuture Detection of Supernova Neutrino Burst and Explosion Mechanism
Future detection of a supernova neutrino burst by large underground detectors would give important information for the explosion mechanism of collapse-driven supernovae. We studied the statistical analysis for the future detection of a nearby supernova by using a numerical supernova model and realistic Monte-Carlo simulations of detection by the Super-Kamiokande detector. We mainly discuss the ...
