1. 1. Faceted conformal antenna arrays analyzed with the uniform theory of diffraction

   Författare :Carina Marcus; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Faceted Conformal Antenna; High-frequency methods; Ray tracing;

   Sammanfattning : Faceted conformal antenna arrays are analyzed with the uniform theory of diffraction (UTD). Parameters such as mutual coupling, scattering parameters, isolated and embedded element patterns are calculated.A ray tracing algorithm for handling rays on a faceted surface, which is needed for the UTD calculations, is also described..

3. 2. Sensor and Signature Modeling for Aircraft Conceptual Development

   Författare :Carina Marcus; Peter Münger; Kristian Amadori; Peter Bull; Christopher Jouannet; Torleif Martin; Kelly Griendling; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The aircraft design process has several phases, the first of which is conceptual design. In this phase, models describing an aircraft concept’s properties are used to evaluate its function and identify designs that meet given requirements. LÄS MER

4. 3. Standardized ultrasonography with cine-loop documentation : diagnostic variability in liver and kidney examinations

   Författare :Stenman Carina; Örjan Smedby; Staffan Wirell; Marcus Ressner; Odd Helge Gilja; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Background: Ultrasound examination of the abdomen is often a first choice at radiology departments due to the lack of ionizing radiation. For diagnostic accuracy and economic benefits there has been a need for new routines in this area that incorporate the benefits of an radiographer or sonographer performing a multitude of ultrasound examinations following strictly standardized examination protocols and documentation forms made by cine-loops that will give the radiologist access to all relevant information needed for an accurate postexamination diagnosis.

5. 4. Model Fidelity in Mission Scenario Simulations for Systems of Systems : A Case Study of Maritime Search and Rescue

   Författare :Sofia Schön; Petter Krus; Christopher Jouannet; Carina Marcus; Kristian Amadori; Alessandro Bertoni; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Systems of Systems (SoS) represent a view where individual, independent systems named Constituent System (CS) collaborate to achieve overarching capabilities not attainable by a single CS alone. In cyberphysical systems, CS can be engineered entities like boats or aircraft, when they collaborate in an environment it can be viewed as an SoS. LÄS MER
