21. Experimental acceleration Measurements and Finite Elements Modeling
Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)Sammanfattning : Heavy crushing machines under their production shifts, creates various levels of vibration, noise and dynamic forces which can be transferred to other parts of the industrial unit. Such kind of factors applies continuous forces on machine parts which can cause gradual fatigue, creep and eventually failure of machine. LÄS MER
22. Online Secondary Path Modelling for Spatial Active Noise Control with Arbitrarily Spaced Arrays
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In this work we explore online secondary path modelling (SPM) in the context of spatial active noise control (ANC). Specifically, we are interested in the reduction of broadband noise over a three-dimensional region, without restrictions on microphone and loudspeaker array placement. LÄS MER
23. In vitro study of Biodegradation in Mg-alloys by Isothermal Calorimetry
Master-uppsats, Lunds universitet/Industriell ProduktionSammanfattning : Magnesium corrosion in an aqueous environment is a multi-layer, complex process. A literature survey shows significant gaps and the modelling work reported indicates a lack of clarity in understanding the corrosion process. LÄS MER
24. An Infrared Stellar Thermometer
Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Infrared (IR) spectroscopy has many advantages over optical, one of which is allowing us to see through intergalactic dust, letting us probe deeper into space and dust-dense regions such as galactic centers. However the investigating the IR spectral range is a relatively new field, owing to recent developments in detector technology, and stellar parameter determination in IR is not well researched.

25. Comparison of control strategies for manipulating a Hydrobatic Autonomous Underwater Vehicle
Master-uppsats, KTH/MekatronikSammanfattning : This master thesis project is focused on the development of an LQR controller and its comparison with other controllers (PID and MPC), in order to successfully control an Autonomous Underwater Vehicle manipulation system. The modelling of the manipulator was performed first in Matlab and later on in Simulink-Simscape. LÄS MER
