1. 1. Direction of Arrival Estimation of Wideband Acoustic Wavefields in a Passive Sensing Environment

   Författare :George Mathai; Fredrik Gustafsson; David Lindgren; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Direction Of Arrival (DOA) estimation has been an active research area for many decades because of its usefulness in many fields, such as wireless communication, navigation, astronomy, surveillance, medicine etc. In DOA estimation, emitted wavefields from unknown sources are measured with the aid of an array of sensors, and this information is then processed to determine various parameters of the sources including the angle between each source and the array.

3. 2. The Core of Aerial Robotic Workers : Generalized Modeling, Estimation, and Control

   Författare :Emil Fresk; George Nikolakopoulos; Thomas Gustafsson; Ming Cao; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerial robotics; generalized modeling; generalized estimation; generalized control; Reglerteknik; Control Engineering;

   Sammanfattning : In this thesis we are going to explore what the operational core, both mathematically and algorithmically, of an Aerial Robotic Worker consists of, in order to estimate its egomotion and parameters, and adaptively control the aerial vehicle. Moreover, the aim of this thesis is to be a condensed reference for the corresponding areas of aerial robotics, in order to provide a stable and complete foundation on which one can continue research on.

4. 3. Human Postural Sway Modeling and Balance Impairment Detection

   Författare :Hedyeh Jafari; Thomas Gustafsson; George Nikolakopoulos; Fredrik Öhberg; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

   Sammanfattning : Falls, Fear of falling (FoF), and low balance confidence pose significant threats to health and independence among older people. This thesis aims to study humans’ postural and balance mechanisms, from analyzing the effect of multisensory inputs on balance performance and balance-related concerns to modeling the postural sway through physical dynamics and data-driven approaches.

5. 4. On Visual Area Coverage Using Micro Aerial Vehicles

   Författare :Sina Sharif Mansouri; George Nikolakopoulos; Thomas Gustafsson; Andreas Johansson; Pantelis Sopasakis; Jana Tumova; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : The aim of this Licentiate is to advance the field of cooperative visual coverage path planners for multiple Micro Aerial Vehicles (MAVs), while aiming for their real life adoption towards the tasks of aerial infrastructure inspection. The fields that will be addressed are focusing in: a) the collaborative perception of the environment, b) the collaborative visual inspection, and c) the optimization of the aerial missions based on the remaining flying battery, camera constraints, coverage constraints and other real life mission induced constraints.

   Sammanfattning : The thesis focuses on the organisation today known as the Swedish Federation for Lesbian, Gay, Bisexual and Transgender Rights (RFSL) and its activities from the founding year 1950 to around 1970. RFSL was the first Swedish organisation that worked for non-heterosexual persons. LÄS MER
