3. 2. Sparse Modeling Heuristics for Parameter Estimation - Applications in Statistical Signal Processing

   Författare :Stefan Ingi Adalbjörnsson; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parameter estimation; sparse models; convex optimization; fundamental frequency; inharmonicity; audio localization; symbolic periodicity; alternating directions method of multipliers; N-dimensional decaying sinusoids.;

   Sammanfattning : This thesis examines sparse statistical modeling on a range of applications in audio modeling, audio localizations, DNA sequencing, and spectroscopy. In the examined cases, the resulting estimation problems are computationally cumbersome, both as one often suffers from a lack of model order knowledge for this form of problems, but also due to the high dimensionality of the parameter spaces, which typically also yield optimization problems with numerous local minima.

4. 3. Combining Task and Motion Planning

   Författare :Fabien Lagriffoul; Alessandro Saffiotti; Lars Karlsson; Malik Ghallab; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

   Sammanfattning : This thesis addresses the problem of automatically computing, given a high-level goal description, a sequence of actions and motion paths for one or several robots to achieve that goal. Also referred to as CTAMP (Combining Task And Motion Planning), this problem may seem trivial at first glance, since efficient solutions have been found for its two underlying problems, namely task planning and motion planning.

5. 4. Processes of accountability. Experience from the operative level in swedish local government

   Författare :Hossein Pashang; Göteborgs universitet; []
   Nyckelord :;

   Sammanfattning : This study is about social and institutional practices of accountability. Firstly, the study develops a framework of accounts. Based on this framework it is argued that accountability arises from practices of using accounts in sequential format in order to influence other's evaluation. LÄS MER

7. 5. Data Abstraction and Pattern Identification in Time-series Data

   Författare :Prithiviraj Muthumanickam; Matthew Cooper; Katerina Vrotsou; Aida Nordman; Jimmy Johansson; Anders Ynnerman; Silvia Miksch; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Data sources such as simulations, sensor networks across many application domains generate large volumes of time-series data which exhibit characteristics that evolve over time. Visual data analysis methods can help us in exploring and understanding the underlying patterns present in time-series data but, due to their ever-increasing size, the visual data analysis process can become complex.
