1. 6. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

   Master-uppsats, KTH/Materialvetenskap

   Författare :Yang Yang; [2020]
   Nyckelord :Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

   Sammanfattning : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

3. 7. Dutch Business case study : Household’s electricity self-consumption maximisation through smart storage and energy

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :FRANCESCO MILANI; [2020]
   Nyckelord :;

   Sammanfattning : In this Master Thesis Project, the business case has been studied for solutions able to monitor the energy balance and maximise the electricity self-consumption of Dutch households, in preparation for the gradual phasing out of the net metering policy starting from 2023. In the initial market research, products investigated were batteries, home energy management systems and hybrid inverters. LÄS MER

4. 8. Acoustic Characterization of the Frequency-Dependent Attenuation Profile of Cellulose Stabilized Perfluorocarbon Droplets

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Lisa Saljén; [2020]
   Nyckelord :Ultrasound; Contrast Agent; Attenuation; Acoustic Characterization; Non Destructive Evaluation; Perfluorocarbon; Droplet; Cellulose; Oscillation; Acoustic Droplet Vaporization;

   Sammanfattning : The use of ultrasound contrast agents increases the information available for reconstruction during ultrasound imaging. Previously studied microbubbles, consisting of a gas core, are subject to limitations such as a short lifetime and a large size. LÄS MER

5. 9. Efficient 2D SLAM for a Mobile Robot with a Downwards Facing Camera

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Christian Colliander; [2018]
   Nyckelord :SLAM; 2D SLAM; Visual SLAM; Quadcopter; Drone; Camera; Downwards facing camera; Computer Vision; Image Analysis; ROS; Robotics; Mathematics and Statistics;

   Sammanfattning : As digital cameras become cheaper and better, computers more powerful, and robots more abundant the merging of these three techniques also becomes more common and capable. The combination of these techniques is often inspired by the human visual system and often strives to give machines the same capabilities that humans already have, such as object identification, navigation, limb coordination, and event detection.

7. 10. High cycle fatigue properties of extruded 6060-T6, 6063-T6 and 6082-T6 : Influence of die lines and microstructure on fatigue in flat extruded aluminum profiles

   Master-uppsats, KTH/Materialvetenskap

   Författare :Sundström Robert; [2018]
   Nyckelord :fatigue; die lines; microstructure; extruded; extrusion; aluminum; aluminium; Al; AlMgSi; Al-Mg-Si; Mg-Si; Si-Mg; flat profile; 6xxx; 6000; utmattning; mikrostruktur; aluminium; aluminum; Al; AlMgSi; Al-Mg-Si; Mg-Si; Si-Mg; extrusion; extruderat; platt profil; 6xxx; 6000;

   Sammanfattning : Aluminum alloys are of great importance in the automotive and truck industries due to the weight savings that they can help to achieve. However, the use of such alloys in applications where they are subjected to alternating stresses requires knowledge about their fatigue behavior. LÄS MER
