1. 1. Sensor Position Optimization for Multiple LiDARs in Autonomous Vehicles

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Rohit Ravindranath Kini; [2020]
   Nyckelord :LiDAR Position Optimization; Point Cloud Density; Genetic Algorithm; PCL; CARLA.; LiDAR Position Optimization; Point Cloud Density; Genetisk Algoritm; PCL; CARLA.;

   Sammanfattning : 3D ranging sensor LiDAR, is an extensively used sensor in the autonomous vehicle industry, but LiDAR placement problem is not studied extensively. This thesis work proposes a framework in an open- source autonomous driving simulator (CARLA) that aims to solve LiDAR placement problem, based on the tasks that LiDAR is intended for in most of the autonomous vehicles.

3. 2. Dynamic First Match : Reducing Resource Consumption of First Match Queries in MySQL NDB Cluster

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Hara Kumar; [2020]
   Nyckelord :“Query Optimization”; “Distributed Databases”; “First Match Query”; Frågaoptimering; ”distribuerad databas”; “första match frågor”;

   Sammanfattning : Dynamic First Match is a learned heuristic that reduces the resource consumption of first match queries in a multi-threaded, distributed relational database, while having a minimal effect on latency. Traditional first match range scans occur in parallel across all data fragments simultaneously. This could potentially return many redundant results. LÄS MER

4. 3. Optimizing multi-robot localization with Extended Kalman Filter feedback and collaborative laser scan matching

   Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

   Författare :Fredrik Ginsberg; [2020]
   Nyckelord :;

   Sammanfattning : Localization is a critical aspect of robots and their industrial applications, with its major impact on navigation and planning. The goal of this thesis is to improve multi-robot localization by utilizing scan matching algorithms to calculate a corrected pose estimate using the robots' shared laser scan data. LÄS MER

5. 4. Material identification using X-ray diffraction

   Kandidat-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

   Författare :Linda Genetu Teggen; [2019]
   Nyckelord :XRD; XRF; incineration; wastemanagement; toxic elements; pollution detection; fly ash; ash; Bruker D2Phaser; DIFFRAC.EVA; chemical filter; scan file.;

   Sammanfattning : This study reviews the theoretical and experimental aspects of the X-ray diffraction (XRD) technique and evaluates its use in identifying toxic elements or compounds in waste that has been incinerated. Many industries incinerate materials that contain large significant amounts of toxic elements, and these elements should be identified and re-moved to reduce environmental pollution. LÄS MER

7. 5. Explaining change : Comparing network snapshots for vulnerability management

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datalogi och datorsystemteknik

   Författare :Andreas Persson; Lukas Landenstad; [2018]
   Nyckelord :Vulnerability management; comparing; vulnerability scan reports; cause of change; decision support system; Sårbarhetshantering; jämförelse; sårbarhetsskanning; sårbarhetsrapport; orsak till förändring;

   Sammanfattning : Background. Vulnerability management makes it easier for companies to find, manage and patch vulnerabilities in a network. This is done by scanning the network for known vulnerabilities. The amount of information collected during the scans can be large and prolong the analysis process of the findings. LÄS MER
