1. 1. Domain-Informed Signal Processing with Application to Analysis of Human Brain Functional MRI Data

   Författare :Hamid Behjat; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :;

   Sammanfattning : Standard signal processing techniques are implicitly based on the assumption that the signal lies on a regular, homogeneous domain. In practice, however, many signals lie on an irregular or inhomogeneous domain. An application area where data are naturally defined on an irregular or inhomogeneous domain is human brain neuroimaging. LÄS MER

3. 2. Using big data to understand evolutionary patterns in Geometridae and Erebidae, the two most diverse families of Lepidoptera

   Författare :Hamid Ghanavi; Biodiversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Lepidoptera (moths and butterflies) are one of the most diverse groups of organisms on earth. They have conquered all the continents apart from Antarctica. The reasons of such high diversity are still not clear. One of the first steps to study the causes of such evolutionary success is to have a clear idea of their phylogenetic relationships. LÄS MER

4. 3. Cryoablation of cardiac arrhythmias

   Författare :Hamid Bastani; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : This thesis evaluates the safety and efficacy of cryoablation in supraventricular tachyarrhythmias. In Study I, the acute and long-term outcome of cryoablation therapy of typical atrioventricular nodal reentrant tachycardia (AVNRT) was studied in a large series of patients (n=312). LÄS MER

5. 4. On Secure and Sequential Source Coding

   Författare :Hamid Ghourchian; Mikael Skoglund; Tobias J. Oechtering; Michèle Wigger; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Secure source coding is an important research area in recent years as it deals with the problem of transmitting sensitive information over insecure channels while protecting it from unauthorized access. This is particularly relevant in the context of modern communication systems where the data transmitted is often sensitive in nature and the threat of eavesdropping or data breaches is high. LÄS MER

7. 5. Postponement and Logistics Flexibility in Retailing

   Författare :Hamid Jafari; Susanne Hertz; Jens Hultman; Anna Nyberg; Mats Abrahamsson; Jönköping University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This dissertation addresses several general logistics problems in retailing regarding meeting a variety of customer demand and availability, efficiency and effectiveness in carrying inventory, and increased logistics flexibility. It builds upon the well-established supply chain principle of postponement, and argues for the benefits associated with it in tackling certain logistics challenges. LÄS MER
