1. 21. Exploring the distribution of accessibility by public transport using spatial analysis : a case study for retail concentrations and public hospitals in Athens

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Evangelos Vafeiadis; [2019]
   Keywords : geography; GIS; spatial analysis; geographic weighted regression; spatial clustering; local indicators of spatial association; public transport; accessibility; Social Sciences; Earth and Environmental Sciences;

   Abstract : This thesis studies the distribution of accessibility by public transport to retail concentrations and public hospitals in Athens, using spatial autocorrelation analysis based on Local Indicators of Spatial Autocorrelation (LISA) method and Geographically Weighted Regression (GWR). For this reason, the study area was divided in a 300x300 meter square grid of points representing the location points of the study. READ MORE

3. 22. Safe Configurable Maps for Off-Road Sites : Proposed methods for safe and efficient map updates for autonomous trucks

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Joakim Christoffersson; [2019]
   Keywords : Maps; updates; autonomous;

   Abstract : Autonomous vehicle technology is advancing at a very high pace and self-driving trucks on control-tower operated work sites is already a reality. These autonomous trucks need a highly accurate map of the surroundings for operation and navigation, and it is of great importance to be able to update that map with the ever-changing off-road work site.

4. 23. Exploration Strategies for Robotic Vacuum Cleaners

   University essay from KTH/Mekatronik

   Author : Sofia Navarro Heredia; [2018]
   Keywords : grid maps; frontier-based exploration strategies; NBV; node graph; path planning algorithm; Rutnätskartor; front-baserade strategier för utforskning; nästa bästa utsiktspunkt; nod-graf; algoritm för banplanering;

   Abstract : In this thesis, an exploration mode for the PUREi9 robotic vacuum cleaner is implemented. This exploration would provide information for optimizing the cleaning path beforehand, and would allow the robot to relocalize itself or the charger more easily in case it gets lost. READ MORE

5. 24. Using Self-Organizing Maps to Identify Operational Risk

   University essay from Lunds universitet/Matematisk statistik

   Author : Lukas Ljungblom; Jonatan Berggren; [2018]
   Keywords : Self-organizing Map; Machine Learning; Neural Network; Clustering; Operational Risk; Audit Change; Mathematics and Statistics;

   Abstract : In recent years, the awareness and concern for operational risk in financial institutions have increased, and several disastrous events in the last two decades been caused by human error. With this, the regulatory demands have increased on the financial institutions to control operational risk. READ MORE

6. 25. Distribution Grid Fault Location : An Analysis of Methods for Fault Location in LV and MV Power Distribution Grids

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

   Author : Jonas von Euler-Chelpin; [2018]
   Keywords : Fault Location; Power Grid; Electricity; Cable fault; Power Distribution; Distribution Grid;

   Abstract : Outages and power interruptions are a common and unenviable part of power distribution system operations. Growing demands on reliability in distribution systems has opened up for new technological solutions for fault location at MV and LV level in distribution systems, previously reserved for transmission systems.
