  4. 12. Requirements Engineering Challenges of Supporting Agile Teams in System Development

    Author : RASHIDA KASAULI; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Safety-critical System Development; Requirements Engineering; Scaled-Agile System Development; User Value;

    Abstract : Context: Agile methods have attracted many companies due to their reported benefits of short time-to-market and improved quality outputs. In the systems development context, additional constraints apply e.g. as a result of scale or parallel development of hardware and software. READ MORE

  5. 13. Dynamic Power System Load -Estimation of Parameters from Operational Data

    Author : Ines Romero; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; robotics; Automation; large disturbances; Load modeling; normal operation; voltage stability; dynamic load models; modeling and identification; normalization in reactive load models; Elektronik och elektroteknik; Electronics and Electrical technology; Automatiska system; robotteknik; reglerteknik; Electrical engineering; Elektroteknik;

    Abstract : The significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. READ MORE

  6. 14. Brain tumors in children - National population-based studies on classification, diagnostics and long-term follow-up

    Author : Elizabeth Schepke; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatric CNS tumors; population-based; DNA methylation; profiling; CNS-PNET; re-evaluation; incidence rate; long-term outcome; classification; Pediatric CNS tumors; Population-based; DNA methylation; Profiling; CNS-PNET; Re-evaluation; Incidence rate; Long-term outcome; Classification;

    Abstract : Although the prognosis for pediatric tumors of the central nervous system (CNS) has improved over time it is urgent to reduce mortality and improve long-term quality of life for survivors. With this aim, the first step is to identify the correct diagnosis in order to choose the right therapy and avoid unnecessary treatment. READ MORE

  7. 15. Runge-Kutta Solution of Initial Value Problems: Methods, Algorithms and Implementation

    Author : Hans Olsson; Institutionen för datavetenskap; []
