2. 1. Dwell time delays for commuter trains : An analysis of the influence of passengers on dwell time delays

   Author : Ruben Kuipers; Trafik och väg; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dwell time; Passengers; Delays; Trains; Railway; Station; Automatic passenger count data;

   Abstract : The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. READ MORE

4. 2. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

   Author : Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time systems; Scheduling; Schedulability analysis; Preemptions; Preemption delays; Embedded Systems; Preemptive scheduling; Response-time analysis; Cache-related preemption delay; Timing analysis; Worst-case execution time analysis; Limited-preemptive scheduling; Fixed preemption points; Computer Science; datavetenskap;

   Abstract : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. READ MORE

5. 3. Quality of control and real-time scheduling : allowing for time-variations in computer control systems

   Author : Martin Sanfridson; KTH; []
   Keywords : real-time scheduling; sampled-data control. Performance measure; quality of control;

   Abstract : The majority of computers around us are embedded in productsand dedicated to perform certain tasks. A specific task is thecontrol of a dynamic system. The computers are ofteninterconnected by communication networks forming a distributedsystem. READ MORE

6. 4. No time to waste : Pre-hospital actions and time delays in patients with ST elevation myocardial infarction – temporal trends and prognostic impact on short- and long-term survival

   Author : Maria Ericsson; Ingela Thylén; Anna Strömberg; Sofia Sederholm Lawesson; Emil Hagström; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Background: In ST-elevation myocardial infarction (STEMI) patients, a rapid diagnosis is imperative to reduce total ischaemic time minimizing risk for heart failure, serious arrhythmias, or death. Prehospital context is complex, and the patient delay constitute major part of the pre-hospital phase. READ MORE

7. 5. Dynamic Programming and Time-Varying Delay Systems

   Author : Bo Lincoln; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; Automatiska system; robotteknik; reglerteknik; robotics; Automation; Stability analysis; Time-varying delays; Dynamic programming; Switched linear systems;

   Abstract : This thesis is divided into two separate parts. The first part is about Dynamic Programming for non-trivial optimal control problems. The second part introduces some useful tools for analysis of stability and performance of systems with time-varying delays. READ MORE
