1. 1. Energy Use as a Consequence of Everyday Life

   Författare :Mattias Hellgren; Kajsa Ellegård; Tommy Svensson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Time use; time-geography; energy use; everyday life; sequence analysis; clustering; Tidsanvändning; tidsgeografi; energianvändning; vardagsliv; sekvensanalys; klusteranalys;

   Sammanfattning : Energy use is a part of everyday life and the use of energy is a part of the global climate change. Policy makers urge individuals to change their daily behaviour in order to mitigate climate change and care for our common environment.The dissertation regards daily behaviour as activities performed by individuals.

3. 2. Adaptive Real-time Anomaly Detection for Safeguarding Critical Networks

   Författare :Kalle Ring Burbeck; Simin Nadjm-Tehrani; Erland Jonsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intrusion detection; anomaly detection; real-time; clustering; adaptation; IP networks; Computer science; Datalogi;

   Sammanfattning : Critical networks require defence in depth incorporating many different security technologies including intrusion detection. One important intrusion detection approach is called anomaly detection where normal (good) behaviour of users of the protected system is modelled, often using machine learning or data mining techniques.

4. 3. On the Size and Shape of Polymers and Polymer Complexes : A Computational and Light Scattering Study

   Författare :Tomas Edvinsson; Terence Cosgrove; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Monte Carlo simulations; grafted polymers; shape description; folding complexity; clustering; percolation algorithm; light scattering; end-capped polymers; inclusion complexes; Fysik; Physics; Fysik; Physical Chemistry; Fysikalisk kemi;

   Sammanfattning : Detailed characterization of size and shape of polymers, and development of methods to elucidate the mechanisms behind shape transitions are central issues in this thesis. In particular we characterize grafted polymer chains under confinement in terms of the chain entanglement complexity and mean molecular size. LÄS MER

5. 4. Route Optimized Energy Management of Plug-in Hybrid Electric Vehicles

   Författare :Viktor Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Convex optimization; Pontryagin principle; Energy management; Dynamic Programming; Data clustering; Splines; Plug-in hybrid electric vehicles;

   Sammanfattning : Plug-in hybrid electric vehicles have the potential to significantly reducethe oil dependence within the transportation sector. However, there willalways be some trips that exceed the electric driving range, meaning thatboth electric energy and fuel must be used. LÄS MER

7. 5. Data Mining Approaches for Outlier Detection Analysis

   Författare :Shahrooz Abghari; Niklas Lavesson; Håkan Grahn; Veselka Boeva; Olga Fink; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; outlier detection; data modelling; machine learning; clustering analysis; data stream mining; Computer Science; Datavetenskap;

   Sammanfattning : Outlier detection is studied and applied in many domains. Outliers arise due to different reasons such as fraudulent activities, structural defects, health problems, and mechanical issues. The detection of outliers is a challenging task that can reveal system faults, fraud, and save people's lives. LÄS MER
