1. 6. Time and energy in long-distance bird migration

   Författare :Thord Fransson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologi; Zoology;

   Sammanfattning : Long-distance seasonal migration is energetically demanding and time consuming. For example, some passerine birds are on migration during six months of the year, travel more than 10 000 km and make use of many fuelling sites. Migration requires many different decisions, and an individual bird will face a variety of situations. LÄS MER

3. 7. Different Aspects of Inference for Spatio-Temporal Point Processes

   Författare :Ottmar Cronie; Göteborgs universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Edge correction; Immigration-death process; Least squares estimation; Maximum likelihood estimation; Spatio-temporal marked point process; Transition probability.; Consistency;

   Sammanfattning : This thesis deals with inference problems related to the Renshaw-Särkkä growth interaction model (RS-model). It is a continuous time spatio-temporal point process with time dependent interacting marks, in which the immigrationdeath process (a continuous time Markov chain) controls the arrivals of new marked points as well as their potential life-times.

4. 8. Enabling Time- and Mission-Critical Applications in Industrial Wireless Sensor Networks

   Författare :Hossam Farag; Mikael Gidlund; Patrik Österberg; Shaofang Gong; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Nowadays, Wireless Sensor Networks (WSNs) have gained importance as aflexible, easier deployment/maintenance and cost-effective alternative to wired networks,e.g., Fieldbus and Wired-HART, in a wide-range of applications. LÄS MER

5. 9. Coordination and Analysis of Connected and Autonomous Vehicles in Freeway On-Ramp Merging Areas

   Författare :Jie Zhu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Operational efficiency; Safety impacts; Freeway on-ramp merging; Microscopic traffic simulation; Connected and autonomous vehicles; Coordinative merging strategy;

   Sammanfattning : Freeway on-ramps are typical bottlenecks in the freeway network, where the merging maneuvers of ramp vehicles impose frequent disturbances on the traffic flow and cause negative impacts on traffic safety and efficiency. The emerging Connected and Autonomous Vehicles (CAVs) hold the potential for regulating the behaviors of each individual vehicle and are expected to substantially improve the traffic operation at freeway on-ramps.

7. 10. Presenting complaint and mortality in non-surgical emergency medicine patients

   Författare :Urban Säfwenberg; Lars Lind; Andreas Terént; Maaret Castrén; Uppsala universitet; []
   Nyckelord :Medicine; Presenting complaint; Emergency Department; long-term mortality; Standardized Mortality Ratio; frequent attenders; Medicin;

   Sammanfattning : In 1995 and 2000 a total of 29 886 non surgical ED visits at Uppsala University Hospital were registered. Presenting complaint, admittance to a ward, length of stay, in-hospital mortality, discharge diagnoses, 30-day and long-term mortality were registered. The presenting complaints were sorted into 33 presenting complaint groups (PCGs). LÄS MER
