2. 1. Computer Assisted Coronary CT Angiography Analysis : Disease-centered Software Development

   Author : Chunliang Wang; Örjan Smedby; Anders Persson; Hans Frimmel; Markus Müller; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary CTA; vessel segmenation; centerline tracking; visualization; Radiology; Radiologi; Image analysis; Bildanalys; Cardiology; Kardiologi;

   Abstract : The substantial advances of coronary CTA have resulted in a boost of use of this new technique in the last several years, which brings a big challenge to radiologists by the increasing number of exams and the large amount of data for each patient. The main goal of this study was to develop a computer tool to facilitate coronary CTA analysis by combining knowledge of medicine and image processing. READ MORE

4. 2. User Requirements Elicitation - A Framework for the Study of the Relation between User and Artefact

   Author : MariAnne Karlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; requirements elicitation; user requirement; user study;

   Abstract : The aim of this thesis is to gain a deeper understanding of the relation between the user and the technical artefact and, further, how this relation can be studied for the formulation and assessment of user requirements. A tentative framework for the study of the user-artefact relation has been derived from adapted theory and experiences from seven empirical studies. READ MORE

5. 3. Computer-­Assisted  Coronary  CT  Angiography  Analysis : From  Software  Development  to  Clinical  Application

   Author : Chunliang Wang; Örjan Smedby; Anders Persson; Hans Frimmel; Evert-jan Vonken; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vessel segmentation; coronary CTA; fuzzy connectedness; level set; coronary artery disease; Image analysis; Bildanalys; Radiological research; Radiologisk forskning;

   Abstract : Advances in coronary Computed Tomography Angiography (CTA) have resulted in a boost in the use of this new technique in recent years, creating a challenge for radiologists due to the increasing number of exams and the large amount of data for each patient. The main goal of this study was to develop a computer tool to facilitate coronary CTA analysis by combining knowledge of medicine and image processing, and to evaluate the performance in clinical settings.

6. 4. Design, analysis and simultion for optical access and wide-area networks

   Author : Jiajia Chen; Lena Wosinska; Hussein Mouftah; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber access networks; passive optical network; dynamic bandwidth allocation; reliability; switched optical networks; switching node; optical circuit switching; optical packet switching; routing and wavelength assignment; security; Telecommunication; Telekommunikation;

   Abstract : Due to the tremendous growth of traffic volume caused by both exponential increase of number of Internet users and continual emergence of new bandwidth demanding applications, high capacity networks are required in order to satisfactorily handle the extremely large amount of traffic. Hence, optical fiber communication is the key technology for the network infrastructure. READ MORE

7. 5. A Verification Framework for Component Based Modeling and Simulation : “Putting the pieces together”

   Author : Imran Mahmood; Rassul Ayani; Gary Tan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling and Simulation; Component-based development; Composability; Semantic Composability; Dynamic-Semantic Composability; Verification; Correctness; Petri Nets Analysis; Algebraic Techniques; Colored Petri Nets; State-space Analysis; Communicating Sequential Processes; Model Checking.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : The discipline of component-based modeling and simulation offers promising gains including reduction in development cost, time, and system complexity. This paradigm is very profitable as it promotes the use and reuse of modular components and is auspicious for effective development of complex simulations. READ MORE
