16. Gate Level Description of Synchronous Hardware and Automatic Verification Based on Theorem Proving
Sammanfattning : Today's hardware development industry faces enormous problems. The primary reason for this is that the complexity of state-of-the-art hardware devices is growing faster than the capacity of the tools that are used to check that they are correct. LÄS MER
17. Applications of the Complex Modulation Transfer Function on SEA-systems
Sammanfattning : The SEA coupling and dissipation loss factors are determined in-situ from Complex Modulation Transfer Functions, CMTF:s, based on measured impulse-responses. A quotient of CMTF:s is least-square curve-fitted to a SEA model and the SEA loss factors are determined from the results of the curve-fit. LÄS MER
18. Speech Enhancement Using Nonnegative MatrixFactorization and Hidden Markov Models
Sammanfattning : Reducing interference noise in a noisy speech recording has been a challenging task for many years yet has a variety of applications, for example, in handsfree mobile communications, in speech recognition, and in hearing aids. Traditional single-channel noise reduction schemes, such as Wiener filtering, do not work satisfactorily in the presence of non-stationary background noise. LÄS MER
19. Enhancing Machine Failure Detection with Artificial Intelligence and sound Analysis
Sammanfattning : The detection of damage or abnormal behavior in machines is critical in industry, as it allows faulty components to be detected and repaired as early as possible, reducing downtime and minimizing operating and personnel costs. However, manual detection of machine fault sounds is economically inefficient and labor-intensive. LÄS MER
