Development of an embedded device for real-time detection of atrial fibrillation and atrial flutter in single-channel ECG, using optimised classification based on a large training corpus

Eric Auer, Oliver Scholz, Daniel Strauss
2021 Zenodo  
The algorithm uses morphological analysis of the averaged ECG shape, properties of the R/R interval distribution and spectral analysis of the ECG to create a feature vector used for classification.  ...  Building on an earlier proof of concept project work by the author, this thesis presents a fully integrated, custom device, using an advanced classification algorithm trained on thousands of short, annotated  ...  In fact, [Reeves 1990 ] has shown in a master's thesis that even 30 years ago, even a 512 × 512 two-dimensional FHT can be used to find the results of a two-dimensional FFT on a desktop computer of the  ...

A coprocessor for fast searching in large databases: Associative Computing Engine [article]

Christophe Layer, Universität Ulm, Universität Ulm
2016
by means of approximate matching procedures.  ...  For that purpose, this thesis describes the development and prototyping of an associative search coprocessor called ACE: an Associative Computing Engine dedicated to the retrieval of digital information  ...  In the ACE computations, the key of a record is the score of a page, and the body of the record includes the page number and the query-related FHT.  ...

Implementation of variable structure control for sampled-data systems [chapter]

Wu-Chung Su, Sergey V. Drakunov, Ümit Özgüner
Robust Control via Variable Structure and Lyapunov Techniques  
Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.  ...  The quality of this reproduction is dependent upon the quality of the copy submitted.  ...  One can choose an appropriate en and obtain the corresponding switching logic (e^, eB,e c ) by looking up Table 1 . Another way of finding en is by using the Hall sensor information.  ...
