1. 6. Automatic Detection of Grammar Errors in Primary School Children's Texts. A Finite State Approach

   Författare :Sylvana Sofkova Hashemi; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grammar errors; spelling errors; punctuation; children s writing; Swedish; language checking; light parsing; finite state technology;

   Sammanfattning : This thesis concerns the analysis of grammar errors in Swedish texts written by primary school children and the development of a finite state system for finding such errors. Grammar errors are more frequent for this group of writers than for adults and the distribution of the error types is different in children's texts. LÄS MER

3. 7. Clinical fluorescence cytometry : improvements to preparation methods and instrumentation

   Författare :Thomas Heiden; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Fluorescence analysis; flow cytometry; image cytometry; DNA ploidy; proliferation; apoptosis; paraffin-embedded tissues; fresh tissues; S-phase fraction; debris; aggregates; spectral overlap; wavelength switching;

   Sammanfattning : Fluorescence cytometry, which can be carried out by flow or image cytometry (FCM, ICM), provides a highly sensitive and specific tool for quantitative analysis of cell material. It is emerging from being a pure research method and becoming an important adjunct to clinical practice. To better realize its potential, more research is needed. LÄS MER

4. 8. Three-dimensional guidance for Endovascular Aortic Repair

   Författare :Giasemi Koutouzi; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anatomy deformation; CBCT; EVAR; image fusion; image guidance; image registration;

   Sammanfattning : Image fusion (IF) of preoperative computed tomography (CT) with intraoperative cone-beam CT (CBCT) is a potentially powerful tool for guidance during endovascular aortic repair (EVAR). It may improve intraoperative anatomic visualization and reduce doses of radiation and contrast medium. LÄS MER

5. 9. Analysis of viral and cellular gene expression patterns in cells latently infected with EBV by suppression subtractive hybridization

   Författare :Csaba Kiss; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :EBV; Suppression subtractive hybridization; high-throughput; DOP-PCR; TCL- 1; BLNK Burkitt s lymphoma; gastric cancer;

   Sammanfattning : Epstein-Barr virus is a ubiquitous γ-herpes virus and causes the self-limiting lymphoproliferative disease, called infectious mononucleosis. Its presence is associated with several malignancies, including Burkitt lymphoma, gastric cancer and other malignant diseases. LÄS MER

7. 10. Charge Sampling Circuits and A/D Converters - Theory and Experiments

   Författare :Gang Xu; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pipelined A D converter; sigma-delta modulator; differential difference comparator; 2-step A D converter; FIR filter; analog filter; thermal noise; clock jitter; sub-sampling; RF sampling; current-mode sampling; Charge samling; A D converter; flexible A D converter; Electronics and Electrical technology; Elektronik och elektroteknik;

   Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER
