2. 1. Functional modelling of the human timing mechanism

   Author : Guy Madison; Uppsala universitet; []
   Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Psychology; Brain mechanisms; Brownian motion; drift; dynamical systems; fractal; human; Gaussian noise; Hurst exponent; time; time series analysis; timing; Psykologi; Psychology; Psykologi; fysiologi; Physiology;

   Abstract : Behaviour occurs in time, and precise timing in the range of seconds and fractions of seconds is for most living organisms necessary for successful interaction with the environment. Our ability to time discrete actions and to predict events on the basis of prior events indicates the existence of an internal timing mechanism. READ MORE

4. 2. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

   Author : Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

   Abstract : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. READ MORE

5. 3. Rethinking Systems of Innovation : Towards an Actor Perspective on the System of Innovation Perspective

   Author : Alina Lidén; Blekinge Tekniska Högskola; []
   Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; systems of innovation; institutions; embeddedness; territorial; functional; Sweden; Ericsson;

   Abstract : In 1987 a book by Chris Freeman with the title “Technology policy and economic performance. Lessons from Japan” was published. This book turned out to be the birth certificate of the systems of innovation perspective which came to enjoy a tremendous popularity the next three decades. READ MORE

6. 4. Real-time Locating Systems for indoor applications : the methodological customization approach

   Author : Bartosz Jachimczyk; Wlodek Kulesza; Alfonso Bahillo Martínez; Blekinge Tekniska Högskola; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accuracy and Precision; Angle of Arrival; Fingerprinting Method; Indoor Localization; Indoor Positioning System; Multi-Sensor System; Neural Network; Radio Frequency Identification - RFID; Real Time Locating System; Received Signal Strength; RFID Network Planning; Scene Analysis; Sensors Arrangement; System Customization; Uncertainty; Uncertainty Map; User Driven Design;

   Abstract : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. READ MORE

7. 5. Brain networks in time : deriving and quantifying dynamic functional connectivity

   Author : William Hedley Thompson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

   Abstract : Studying the brain’s structure and function as a network has provided insight about the brain’s activity in health and disease. Networks in the brain are often averaged over trials, frequency and time and this is called functional connectivity. This thesis aims to extend the analyses beyond these assumptions and simplifiations. READ MORE
