Error propagation in concurrent product development
… Depending on the type of project, some design errors may only be discoverable once the build phase has begun its work. Namely, systemic errors and assembly errors that cannot be easily discovered within the design phase. Pushing build activity earlier in the project allows the rework to be …

SEU-Induced Persistent Error Propagation in FPGAs
… section can statically be determined. Functional error mitigation techniques can leverage this identification to improve the reliability of some applications at lower costs by focusing mitigation on just the persistent cross section. The reliability of a practical signal processing application in …

Noise and error propagation in diffusion tensor imaging
… and the MRI scanner. This thesis studies the error propagation in the calculation of the DTI invariant anisotropy, mainly the Fractional Anisotropy (FA) using four methods and their comparison in terms of error, filtering and computational efficiency using simulated and human brain data. These …

Error propagation of optimal system design in a hierarchical enterprise
… model is introduced where different forms of error can be introduced at each level. Error derived from both measurement inaccuracy and modeling inaccuracy is examined coupled with the effect of system constraints as well. A hierarchical decomposition method is selected for its similarity to a …

Probabilistic Estimation of State via Propagation of Error for a Collision Warning System
… for vehicles following a flight path. Error propagation is the methodology used by the FSE because minimal information is required for implementation. A point mass system involving a UAS following a flight path is the model used for deriving the error propagation in the vehicle's body …

Quantifying software architecture attributes
… tries to use software metrics to represent the error propagation probabilities, change propagation probabilities, and requirements change propagation probabilities of a software architecture. Error propagation probability reflects the probability that an error that arises in one component of the …

Towards Explainable Event Detection and Extraction
… to obtain document probabilities resulting in error propagation. To alleviate this problem we propose to leverage recent advances in representation learning by using attention mechanisms. Specifically, for event detection we propose a method to compute document embeddings from sentence …

3D Object Detection for Road Safety at Urban Intersections
… on intersection safety. I highlight potential error propagation in prior SSA methods in the literature review. My first significant contribution was to evaluate the error propagation of 2D and 3D object detection models for SSA. To achieve this, I built a bespoke conflict simulator to generate …

Data Compression Strategies for RDAT/DDS Media in Hostile Environments
This thesis investigates the prevention of error propagation in magnetically recorded compressed data when severe environmental conditions result in uncorrected channel errors.<br/><br/>The tape format DDS is examined and a computer simulation of its error correction procedures is described. This …

Performance Evaluation of Multiuser Detectors with V-BLAST to MIMO Channel
… Next, the V-BLAST algorithm is reviewed and the error propagation of this algorithm is investigated. Then, the V-BLAST algorithm is combined with multiuser receivers to achieve high channel capacity while sharing the spectral resources over a MIMO channel. A bias reduction technique is considered …

From detection to optimization: impact of soft errors on high-performance computing applications
… on HPC system design forces the handling of errors to higher levels in the software stack. Of the types of errors facing HPC, soft errors that silently corrupt system or application state are among the most severe. The behavior of HPC applications in the presence of soft errors is critical to …

Automated wavelet analysis of low resolution gamma-ray spectra and peak area uncertainty
… The matrix form of wavelet transform and error propagation are used. The inversion of the basis matrix is obtained either by the Moore-Penrose pseudo inversion or by truncated singular value decomposition (TSVD). The results are compared with those given by OriginLab and Gaussian fitting …
