   Sammanfattning : Modern vehicles have several autonomous and semi-autonomous features, such as adaptive cruise control, lane keeping, adaptive headlights, and automatic emergency braking, ensuring a safe and comfortable driving experience. The vehicles typically rely on different sensors to "see" their surroundings and make decisions accordingly. LÄS MER

   Sammanfattning : Objective: To study maternal smoking in pregnancy in relation to preterm birth, placental abruption and perinatal mortality in pregnancies with placental abruption, and to pulse wave characteristics in fetal aorta. Methods: Two cohort studies with data on single births obtained from the Swedish Medical Birth Registry (N=311 977 and N=795 459, respectively). LÄS MER

7. 15. On Nonlinear Acoustics in Contrast Echocardiography

   Författare :Marcus Ressner; Birgitta Janerot-Sjöberg; Per Ask; Tomas Jansson; Hans Torp; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Ultrasound is one of the most commonly used noninvasive medical imaging techniques. Ultrasound contrast agents (UCA), consisting of encapsulated gas-filled microbubbles, have shown to increase the diagnostic precision in selected low echogenic patients. LÄS MER
