1. 1. Heuristic Clustering Methods for Solving Vehicle Routing Problems

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Georgios Nordqvist; Erik Forsberg; [2023]
   Nyckelord :optimization; vehicle routing problem; sweep clustering; k-means clustering; hierarchical clustering;

   Sammanfattning : Vehicle Routing Problems are optimization problems centered around determining optimal travel routes for a fleet of vehicles to visit a set of nodes. Optimality is evaluated with regard to some desired quality of the solution, such as time-minimizing or cost-minimizing. LÄS MER

3. 2. Robust Perception for Formula Student Driverless Racing

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Gustaf Broström; David Carpenfelt; [2021]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Building an autonomous system for race cars requires robust and highly accurate perception running in real time. This thesis proposes a novel ground removal strategy for 3D LiDAR perception, modelling the ground as several planes, and a novel clustering method for LiDARs that sweep the scene in a predefined pattern resulting in a 20-fold performance increase over clustering methods commonly used for this problem.

4. 3. LiDAR Pedestrian Detector and Semi-Automatic Annotation Tool for Labeling of 3D Data

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Roy Andersson; Erik Andersson; [2019]
   Nyckelord :LiDAR; Machine Learning; Pedestrian Detection; Annotation; DBSCAN; SVM; Technology and Engineering;

   Sammanfattning : The goal of this Master's Thesis is to successfully detect and classify humans in a LiDAR data stream. The focus of the Thesis is on the detection and classification, not on the LiDAR technology. To classify humans machine learning was used and to train the machine learning model we collected our own data and annotated it. LÄS MER

5. 4. Sensor-less Smart Waste Management System

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Rahul Sridhar Setty; [2019]
   Nyckelord :;

   Sammanfattning : In order to improve the municipal solid waste management efficiency, smart management approaches have been proposed such as wireless sensor network architecture solution which includes the use of sensors to detect the garbage bin fill levels and vehicle route optimization techniques. Experimental results show that we can save up to 35% of the operational cost by improving the efficiency of solid waste management. LÄS MER

7. 5. An Explorative Parameter Sweep: Spatial-temporal Data Mining in Stochastic Reaction-diffusion Simulations

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Fredrik Wrede; [2016]
   Nyckelord :Big data; feature extraction; clustering; stochastic reaction-diffusion simulation; spatial-temporal; data mining; cloud computing;

   Sammanfattning : Stochastic reaction-diffusion simulations has become an efficient approach for modelling spatial aspects of intracellular biochemical reaction networks. By accounting for intrinsic noise due to low copy number of chemical species, stochastic reaction-diffusion simulations have the ability to more accurately predict and model biological systems.
