1. 1. Preprocessing perceptrons

   Författare :Lena Kallin Westin; Patrik Eklund; Lothar Gierl; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datalogi; Preprocessing perceptron; Production line; Neural networks; Backpropagation; Fuzzy logic; ROC and QROC curves; Multivariate decision limits; Datalogi; Computer science; Datalogi; business data processing; administrativ databehandling;

   Sammanfattning : Reliable results are crucial when working with medical decision support systems. A decision support system should be reliable but also be interpretable, i.e. able to show how it has inferred its conclusions. LÄS MER

3. 2. Multimodal applications in medical technology that utilize Raman spectroscopy

   Författare :Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Thomas Bocklitz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Raman spectroscopy; Preprocessing; Pulmonary arterial smooth muscle cells; Brain tumors; Experimental Mechanics; Experimentell mekanik;

   Sammanfattning : Biology can often be explained by structures and interactions between molecules. It is therefore of importance for medical sciences that the chemical reactions and molecular compositions of biological samples can be measured. The purpose of this thesis is twofold. LÄS MER

4. 3. Morphosyntactic Corpora and Tools for Persian

   Författare :Mojgan Seraji; Joakim Nivre; Carina Jahani; Jan Hajic; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Persian; language technology; corpus; treebank; preprocessing; segmentation; part-of-speech tagging; dependency parsing; Computational Linguistics; Datorlingvistik;

   Sammanfattning : This thesis presents open source resources in the form of annotated corpora and modules for automatic morphosyntactic processing and analysis of Persian texts. More specifically, the resources consist of an improved part-of-speech tagged corpus and a dependency treebank, as well as tools for text normalization, sentence segmentation, tokenization, part-of-speech tagging, and dependency parsing for Persian.

5. 4. Development of Preprocessing Methods for Multivariate Sensor Data

   Författare :Tom Artursson; Corrado Di Natale; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In this work various aspects of data preprocessing are discussed. Preprocessing of data from multivariate sensor data systems is often necessary to extract relevant information or remove disturbances. Depending on the sensor type different preprocessing techniques have to be used. A number of important problems face the user e. LÄS MER

7. 5. Adaptive Baseband Pro cessing and Configurable Hardware for Wireless Communication

   Författare :Rakesh Gangarajaiah; Integrerade elektroniksystem; []
   Nyckelord :Wireless receivers; baseband processing; LTE-A; MIMO; OFDM; carrier aggregation; channel preprocessing; adaptive signal processing; non-linearity mitigation; massive MIMO;

   Sammanfattning : The world of information is literally at one’s fingertips, allowing access to previously unimaginable amounts of data, thanks to advances in wireless communication. The growing demand for high speed data has necessitated theuse of wider bandwidths, and wireless technologies such as Multiple-InputMultiple-Output (MIMO) have been adopted to increase spectral efficiency.
