2. 1. Protection and treatment of hypothermia in prehospital trauma care : with emphasis on active warming

   Author : Peter Lundgren; Ulf Björnstig; Peter Naredi; Tore Vikström; Anne Guttormsen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hypothermia; kirurgi; Surgery;

   Abstract : Background: In prehospital trauma care active warming is recommended to aid in protection from further cooling. However, scientific evidence of the effectiveness of active warming in a clinical setting is scarce. Also, evaluating the effectiveness of active warming, especially in harsh ambient conditions, by objective measures, is difficult. READ MORE

4. 2. Cold exposure and thermal comfort among patients in prehospital emergency care : innovation research in nursing

   Author : Jonas Aléx; Britt-Inger Saveman; Stig Karlsson; Ulf Björnstig; Inggard Lereim; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thermal comfort; thermal discomfort; cold exposure; cold stress; hypothermia; patients’ experiences; active warming; prehospital emergency care; finger temperature; back temperature; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

   Abstract : BackgroundPatients’ cold exposure is a neglected problem in prehospital emergency care. Cold stress increases pain and anxiety and contributes to fear and an overall sense of dissatisfaction. When left untreated, cold stress disturbs vital body functions until ultimately reaches hypothermia. READ MORE

5. 3. Vehicle Dynamic Opportunities in Electrified Vehicles for Active Safety Interventions

   Author : Adithya Arikere; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rear-end collisions; active safety; vehicle dynamics; obstacle avoidance with oncoming traffic; speed control; electrified drivetrain; torque vectoring; driver assistance systems;

   Abstract : Although the sales of electrified vehicles is growing, studies indicatethat the growth is inadequate to sufficiently reduce CO2 emissions andmitigate global warming. Some form of added incentive is needed to driveelectrified vehicle sales. READ MORE

6. 4. Vehicle Dynamics Control for Active Safety Functions using Electrified Drivelines

   Author : Adithya Arikere; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver assistance systems; intersection accidents; torque vectoring; optimal control; rear- end collisions; speed control; active safety; vehicle dynamics; electrified drivetrain; obstacle avoidance with oncoming traffic;

   Abstract : Studies have shown that even considering pledges and commitments made by various governments and organisations, the growth in electrified vehicle sales is likely to be insufficient to reduce CO2 emissions for mitigating global warming. Some form of added incentive is needed that can help drive electrified vehicle sales in the open market. READ MORE

7. 5. Experimental Study on Truck Related Power Losses: The Churning Losses in a Transmission Model and Active Flow Control at an A-pillar of Generic Truck Cabin Model

   Author : Erwin Adi Hartono; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot wire anemometry; Machine learning; Computational Fluid Dynamics; A-Pillar; Transmission; Flow separation; Churning losses; CFD; Gearbox; Torque measurement; Particle Image Velocimetry; Smoothed Particle Hydrodynamics.; Active Flow Control; SPH; Curve fit; Synthetic Jets; Load independent power losses; Aeration; Flow visu- alization;

   Abstract : The fight with global warming constantly forces vehicle manufacturers to innovate, in order to be able to reduce the CO2 emissions of their product. This means that marginal efficiency gains in every component are considered beneficial for total reduction of CO2 emissions. READ MORE
