  1. 6. Identification of dynamic errors-in-variables models

    University dissertation from Uppsala University

    Author : Kaushik Mahata; Uppsala universitet.; Uppsala universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

    Abstract : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. READ MORE

  2. 7. The complexity and variability of individuals' activity-travel patterns in Indonesia

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Dimas Bayu Endrayana Dharmowijoyo; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; day-to-day variability; needs-constraints interaction; non-instrumental variables; health condition; Transportvetenskap; Transport Science;

    Abstract : Considering an individual’s day-to-day variability of activity-travel patterns will provide a more complete description of how an individual behaves to adapt the changing constraints and resources on different days. Without this day-to-day variability understanding, the individual’s behaviour would not be fully grasped and any suggested policy, planning and development would not completely achieve their desired objectives.

  3. 8. On two methods for identifying dynamic errors-in-variables systems

    University dissertation from Uppsala University

    Author : Mei Hong; Uppsala universitet.; Uppsala universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : Identification of dynamic errors-in-variables systems, where both inputs and outputs are affected by errors (measurement noises), is a fundamental problem of great interest in many areas, such as process control, econometrics, astronomical data reduction, image processing, etc. This field has received increased attention within several decades.

  4. 9. Indirect System Identification for Unknown Input Problems With Applications to Ships

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Jonas Linder; Linköpings universitet.; Linköpings universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Model structure; Unknown inputs; Indirect input measurements; Physical models; Instrumental variable; Closed loop; Graybox model; Identifiability; Ship; Marine vessel; Operational safety; Inertial measurement unit;

    Abstract : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. READ MORE

  5. 10. Perinatal Complications: Associations with Postpartum depressive symptoms and Neuroticism

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Patricia Eckerdal; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antenatal depression; ceasarean section; delivery complications; Edinburgh postnatal depression scale; EPDS; epidural analgesia; gestational diabetes mellitus; instrumental delivery; neonatal complications; neuroticism; obstetric complications; personality; perinatal complications; postpartum depression; postpartum haemorrhage; pregnancy complications; vacuum extraction; vaginal delivery; Obstetrik och gynekologi; Obstetrics and Gynaecology; Psychiatry; Psykiatri;

    Abstract : Even though most pregnancies and deliveries are uncomplicated, still fifteen percent of all women in developed countries suffer pregnancy-related complications. The aim of this thesis was to explore the associations between perinatal complications and perinatal maternal health, with emphasis on postpartum depressive symptoms (PPDS) and neuroticism taking into account potential confounding or mediating factors such as history of depression, antenatal depressive symptoms and delivery experience.
