1. 11. Memory Efficient Hard Real-Time Garbage Collection

   Författare :Tobias Ritzau; Peter Fritzson; Roger Henriksson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hardware progresses; programming languages; garbage collector; real-time reference counting; object ownership; static garbage collector; embedded systems; Computer science; Datavetenskap;

   Sammanfattning : As the development of hardware progresses, computers are expected to solve increasingly complex problems. However, solving more complex problems requires more complex software. To be able to develop these software systems, new programming languages with new features and higher abstraction levels are introduced. LÄS MER

3. 12. Can improved paediatric pneumonia diagnostic aids support frontline health workers in low resource settings? Large scale evaluation of four respiratory rate timers and five pulse oximeters in Cambodia, Ethiopia, South Sudan and Uganda

   Författare :Kevin Baker; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Pneumonia is the leading cause of infectious death in children under-five in sub-Saharan Africa and Southeast Asia. Currently, the diagnostic criterion for pneumonia is based on increased respiratory rate (RR) in children with cough and/or difficulty breathing. LÄS MER

4. 13. Design of VCO-based ADCs

   Författare :Vishnu Unnikrishnan; Mark Vesterbacka; Trond Ytterdal; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Today's complex electronic systems with billions of transistors on a single die are enabled by the aggressive scaling down of the device feature size at an exponential rate as predicted by the Moore's law. Digital circuits benefit from technology scaling to become faster, more energy efficient as well as more area efficient as the feature size is scaled down. LÄS MER

5. 14. DIXI – a Hybrid Pixel Detector for X-ray Imaging

   Författare :Fredrik Edling; Richard Brenner; Leif Gustafsson; Camilla Rönnqvist; Peter Fischer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; hybrid pixel detector; photon-counting; X-ray; imaging; simulation; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

   Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER

7. 15. Mitigation of Pressure Pulsations in Francis Turbine Draft Tube with a GuideVane System : A Numerical Investigation

   Författare :Jesline Joy; Michel Cervantes; Cécile Münch-Alligné; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational fluid dynamics; Francis turbine; Part load; Reduced modelling; Rotating vortex rope; Strömningslära; Fluid Mechanics;

   Sammanfattning : The use of renewable energy such as water and wind to produce electricity has been proven extremely effective in Sweden. The ability of these renewable resources to produce clean output energy counters the adversities caused by non-renewable resources. LÄS MER
